Page Twenty-Two - Body Panels, Baby!


Page 22 in 2022, kind of a symmetry to it, huh?  It's starting to resemble a car!

A year ago, I ordered eight replacement body panels from Classic Sunbeam, front quarter panels, rocker panels, front rear wing panels, and rear wing lower panels all around, eleven months ahead of when I needed them.  In my defense, there’s a lot of fitting and head scratching that happens before you drag out the welders.  It’s good to be ahead of the game, but I made mistakes…

Rocker Panel:  Let’s start with something I got right.  The rocker fit and welded into place easily.  The front edge where the rocker meets the front wing panel will require some thinking and massaging, haven’t go to that yet.  The rear of the rocker mated with the rear, front patch panel nicely.  Ah, if the other panels had gone so well.

The rocker has one problem -
This joint will need some work.

Big Mistake:  Look back at the September 2020 post called “Winging It”.  You will remember that I had to rebuild the inner wings on each side.  I was very proud of the work but… Mind you, I built the inner wings before I fitted the Organ Donor’s snoz to Alphie, meaning the measurements were “preliminary,” aka, wrong.  That bill has come due.

The yellow arrow points to where I ground down the inner panel from the outside.  The blue arrow shows where the inner panel is still pushing the wing out and creating a high spot.  The wise man (not me) would have checked that before pulling the fender into place at the bottom pinch weld.  


From inside the wheel well

So how to fix it.  I started by cutting through the wing and grinding down the inner panel and welding it back together, figuring I would have to do body work to fix it anyway.  It fixed it, but it’s very sloppy and just not good craftsmanship.  And it didn’t fix it as completely as I thought, the upper part of the inner wing is still pushing out the wing.  This time I cut the inner wing from inside the wheel well and messaged the high spot down.  I will have to close the gap between the inner wing and the wing with body sealer, but I was going to do that for other areas of the inner wing anyway.  I won’t make the same mistake on the passenger side.  It’s not that I’m not above screwing up again, but I like to challenge myself with new lack-of-foresight mistakes.

Front, Rear Wing Panel:  Confused?  The one behind the door at the leading edge of the rear wheel well.  Look at the pics.  I had an issue there, partly my fault, partly the panel’s fault. 


Front, Rear Wing Panel -
fixed but too much welding
Front, Rear Wing Panel -
a strip added to cose the gap




















The panel was too short to meet the edge of the door, not sure why, but “their” fault.  It forced me to cut a slit where the edge of the panel could be slotted into Alphie’s quarter panel, which I cut in the wrong place, leaving a large gap between the quarter panel and the patch panel.  My fault, and my second big mistake.

To fix the gaping wound, I scrounged my supply of Lowes sheet metal.  I made a quick file folder template, transferred it to the metal, cut it out and got to MIGging.  A solid fix, but the type of excessive metal splicing I prefer to avoid.

Wing Lips:  First challenge on both the front and rear wing patch panels is the wheel well lips.  Get the shape of the wing lip wrong, and it will scream “patch panel” for miles.  The weld along the panel is easily hidden but screw up the shape of the lip, and it’s as obvious as a turd in a punch bowl.


A lot of rust means I needed a patch panel for the patch panel

Confusing isn't it?


Not there yet, but the lip is shaping up

Get you some of these!
Lip shape became my focus.  I would hedge a little in other areas if needed to get the lip edges right.  The wing lip must run smooth and true from every angle.  I did a lot of staring and checking stuff with straight edges and contour gauges.  Also, plastic filler on the wing lip is a bad idea because it will chip easily and, because the filled areas are so small, the filler can come loose.  I filled the lips themselves and the curved area above them by building up welding rod and carefully grinding the welds to shape.  I filled the pock marks and grinding scratches with JB Weld because it is more tenacious and tougher than body filler.

Body Solder vs Plastic Filler:  I spent some time studying this question.  I said earlier in this blog, that I was going to body solder the patch panel welds because it was “structural” while goop isn’t.  Many interwebbers pointed out that welding is the most “structural” of any fix – the previous bloke fixed Alphie’s left rear wing’s lower cheek by pop riveting in some flimsy sheet metal and slathering on enough goop to sculpt out the shape.  Other webbers argued that goop has come a long way and that fiber glass reinforced filler is a strong and more flexible that body solder was back in the day.  Others argued that body solder requires experience, and that insufficient prep can lead to weak solder adhesion and insufficiently cleaned tinning acid to rust from beneath the solder.  Many webbers warned that the heat of tinning the metal can easily warp the panel.  You can quickly put too much heat into the panel before you know it.  That was the concern that got my attention.

Fiber glass reinforced gooped.  Pic doesnt show it, but the lip shape is very close

Here’s the deal, plastic filler and I go way back.  I know what it can and cannot do, what it looks like when it is right and when it is wrong.  From long experience, I can read it as I sand it, so I’m comfortable with the goop.  But I am using the good stuff, money spent on quality filler is not wasted, and I put fiber glass reinforced stuff directly on top of the welds.  As one of the webbers put it, the only reason the old timers used body solder, is because they didn’t have goop.

Oh, I got a Harbor Freight Dent Repair Stud Welder too.  It’s awesome, more on than later.

Worth it!

Door Fitment:  I gutted the driver’s door and reinstalled it to see how bad the gaps were.  Not horrendous, but not good either.  The gaps are a problem (see below) but not the only problem. 

The door hangs about 90% correctly.  The front edge mates up smoothly, but the rear edge is higher than the body.  A curious problem because I had already fiddled with the hinges, moving them in and out to not only mitigate the gaps but to fit the door itself smoothly in line with the body surfaces.  Shimming the hinges may fix the rear edge but would mess up the front edge.  I turned my attention to the body just behind the rear door edge.  There was a dent where someone (I surmise) had slammed the hard top on to the body.

So, I fired in a stud from my handy stud welder and pulled out the dent.  With some minor hammer and dolly work on the rear edge of the door, the matchup is significantly better.  The weight of the window regulator and other assorted window apparatus will probably bring everything into line.  At least, that’s what I’m telling myself.

The door is slightly higher,
 but close enough for now

Body panel gaps:  The gap between the bottom of the door and the rocker, good.  The gap between the rear of the door and rear wing, meh.  The gap grows at the top of the door, but that will be easily fixed by welding in a strip of sheet metal (maybe two) and smoothing out the welds.  But the gap between the front of the door and the front wing, we’ll generously say “ragged.”  The gap is too tight at the bottom where I welded in the patch panel, but it becomes a crevice at the top curve of the door.

Front Wing/Door Gap:  With the door reinstalled, the front wing/door gap doesn’t match the curve of the door.  I maneuvered the door on its hinges until I got the fitment as close as I could everywhere but the front gap, leaving it last.  Clearly, I had to add metal to match the curve and fix the excessive gap.

Red - too wide, Yellow - too tight
I cut a file folder template to the shape of the door curve, measured the gap at what appeared to be the correct gap, compared the measurement to other gaps around the door, and taped the template to the front wing top.  Now I have an idea of how much metal to add.

Next, I made a file folder template of the shape where the metal would need to go and cut a piece of the thickest sheet metal I had.  Beat, filed, and cut the metal to shape and MIGed away.

With the first filler piece welded in, you can see that I need some more to close the gap completely.  The weld joint where I welded the wing to Alphie will get gooped where the Rootes folk body soldered it back in 1964.

Page Twenty-One: Mending Shite

 

Mostly pictures this time, some examples of small rust-through mends.

First up, the forward, driver's side corner of the trunk.  Water leaks either through the soft top or under the hard top, down into the trunk and puddles at the corners.  In short, rust-throughs.

Witness the rust-through from rear driver's side fender well




First - cut out the cancer

Next - size a new chunk of tissue

Next - tack-weld it in place. (I trimmed the donor tissue to fit before welding.)

Finish - several things: completed welding, ground the welds and shot on some self-etch primer

The last pic doesn't show it, but the weld shows some.  I may smooth it out with some JB Weld or I may not worry about it because it will rarely be seen under the car.  (I'll probably smooth it out because it will bug me that my mending will show to the discriminating eye.)  Also, you'll notice in the last pic that I found another rust-through.  It was a rust bubble that I started picking at with the spike of my body hammer. It will get a patch too.  Mend one, find one more - it's the way...

The tumor after removal
Next up, a really manky piece of trunk floor inside the bodgy butt-cheek.

The first pic shows the tumor after removal.  It's too rusty to weld, and I'm not putting anything this nasty back in Alphie.

Not shown in the pics: I made a paper template from the tumor and approximately fitted it to its spot.  I cut out a piece of 20 gauge sheet metal and fitted it more precisely to the spot.  "Fitted" implies hundreds clamps into place followed by scrutinze along with trips to the vise for filing, grinding, welding, hammering, more grinding and filing, more fiddling!  It's not a quick fix!

Flanges are boxed in with a small piece to close up a gap in the frame rail

Tacked in place to check fitment

The pics don't show how much time it took to fit the piece to the space and get the pitch of what will be the pinch weld around the boot pan and into the rear wing pinch weld.

Glued!

The welds are a bit messy right now, and you will notice some burn-through where the fender well meets the new piece, and some gaps where I'll need to replace some more rusty trunk floor pan.  I will cover the ugly welds with either JB Weld or seam sealer, eventually.  I know, it's under the car, but still...

The rear-wing patch panel is not welded in yet as I have some more fiddling to fit it perfectly.  I'll show you how I fitted the patch panel soon.

Before and After

It occurred to me that a good way to show how much Alphie has healed is to show a before and after shot of the photo used as the masthead to this blog page:
Before (2019) - when I first dug into the rust!

After (2021) - the same spot, post tissue grafts!

Two More Before and Afters

After (2021) - same spot after lots-o-mending

Page Twenty: Bodgy Boot Cheeks

 


The next skirmish in the battle against demon rust, brings us to the left crumbly, ragged rear quarter panel.

Like all Alpines, water trickles through gaps where Alphie’s roof meets body, down the inner wings, finally spreading out along the boot floor, feeding demon rust.  You may recall that the petrol tanks (again, remember that Series IV Alpines have two tanks in each rear wing), which sweat (and possibly leak) into the boot as well.  In short, a lush lair for rust!

Our cadaver studies provide a pattern – we have two cadavers to consult for Operation Bodgy Boot Cheeks, the Organ Donor and Bob’s Butt.  (You remember Bob’s Butt, the arse-end of a Sunbeam Tiger that Bob, my Sunbeam buddy gave to me?)  Bob’s Butt donated some flesh for transplanting as well.

Like everything else on Alphie, the rust goes farther than I expected, even though my rust expectations are quite high.  Cutting away the manky left rear boot cheek revealed rotten inner fenders, cancerous sections of boot floor, random rust-throughs, and a bent and rusty rear jack point, which was also surrounded by more flaky sheet metal.  Peruse the pics.

Loads of Flaky Rot

Cut away view - LOTS cut away!

Cancerous inner-fender well

With Bob’s Butt as a guide, I decided that the most effective fix for Alphie’s jack point, was to amputate the one from Bob’s Butt.  Sounds simple enough, but to get the grinders (it took two sizes) and the Sawzall in there, meant that I had to cut up the jack point enough to require a “repair” before it could be transplanted. 

Usage Note:  One jacks an Alpine using a rickety design where one inserts the jack’s square tube appendage into a square hole below the bumper.  The hole is a length of square tubing, slightly larger than the jack’s appendage, which is welded to the frame at the rear quarter.  Confused?  The pics may help you visualize.

Using Bob's Butt to demonstrate,
this is how an Alpine is jacked.















Cut away showing how
the jack point works

I had to cut through a portion of the square tubing to rend the jack point from Bob’s Butt, meaning I would have to weld on a replacement length of square tubing to the excised jack point.  Turns out, Lowes doesn’t sell 1” square stock in a beefy enough gauge to handle being a jack point.  But they sell angle iron that can not-so-conveniently be welded to create square stock.  A small pain but it didn’t take too much time.

Once I had cut back the sheet metal to cancer-free areas, I saw that when someone jacked Alphie at some point, he/she/it either were on uneven footing or the jack teetered with the car in the air – whatever the case, the jack point, the sheet metal surrounding it and, not surprisingly, the frame rail itself were bent.  With careful application of grinders and Sawzall, I ripped the old jack point out, and with contortions worthy of a circus act, beat the frame rail back into shape with hammer and dolly, and judiciously scrubbed off the rust.  The patient is prepped for her transplant.

Amputated jack point and its prosthetics

I clamped the donated jack point from Bob’s Butt onto Alphie’s frame and marked cut lines onto Alphie’s butt pan.  Next, I cut at the lines, and test fitted the new jack point.  After some filling and other adjustments, fit was better than I expected.  So, I welded the jack point to the frame rail first so that I had a solid, final placement.  Some body-hammering and fitting lined up the jack point with Alphie’s butt pan, and some quick spot welds connected Bob’s skin to Alphie’s.  The rotisserie mount obstructs finish welding, but I can get to it when Alphie comes off the rotisserie.

Cleaned and ready for transplant

Skin graft - this will need finish welding and grinding

With the jack point secured, I turn my attention to fitting the lower boot cheek patch panel.  For now, it’s vice-gripped in place while I measure both the right and left fender lowers.  I need to be sure that I have the patch panel in the correct spot, not too high or low.  To get a fix on it, I’m measuring from the boot floor to the bottom of the right fender tip at the base of the wheel well using a framing level to get a precise and consistent placement on each side.

Test fitting the patch panel - needs tons of scrutiny and fitting

At this post, I’m hesitant to cut the rear wing anymore until I’m satisfied that I have the correct placement.  As it is, I will need to add patches above the patch panel because I had to cut more fender flesh to get to the rusty inner fender.  I’ll update this post as I perfect the patch panel’s fit.

Page Nineteen - Floorboardin'

 

Ready for the mean streets of Bedrock

Besides fenders and grills, the most endangered part of a “vintage” car (alright, old piece of sh*@#) are the floorboards.  Of course, if you park a convertible in the weather for 30ish years, everything is endangered.  Alphie spent her coma years mostly undercover, but her floorboards endured much rustage, like something cruising the mean streets of Bedrock.

I had already chewed into her floorboards when I was working on the center X frame, but I got down to business to fit the replacement skins I bought from David Lamerant up Canada way.  Mr. Lamerant punches out metal panels with all the molded strengthening reliefs as the original, but he doesn’t cut them to size or bend them to fit the curves of the interior.  (Honestly, he can’t because everyone’s Alpine/Tiger suffers different rustage configurations.)  But he gives you plenty of extra metal around the edges to cover any situation.

After much grinding, cutting, sawzalling, cussing and a little bleeding, I wrested the old floorboard from the area where the Lamerant panel will sit.  I cleaned all the undercoating from the X member since it was easily accessible and slathered on a coat of POR 15 to stop rust.  Crackin’!  The job took four hours, but it was the easy part.

The hole to fill

Fitting the patch panel took a day, not welding, just fitting.  First, file folders.  I masking-taped a flotilla of file folders to make a template to fit Alphie’s bod.  Before Alphie, I laid the template on the Lamerant panel and marked the strengthening reliefs so that I could match the original placements as best I could.  Next, I threw it down on Alphie’s invisible floor and penciled around the edges, allowing some space for screwing up.  Attack the template with scissors and toss it back in to check the fit.  Pencil in the areas that don’t fit, attack with scissors, check the fit, pencil the errors, attack with scissors, cut too much, fix with tape and file folder scraps, check the fit, pencil, scissors, yada yada… Eventually, I achieved “close enough” status.

File folders at "close enough"
Before I cut any sheet metal, I knew that I needed a down turned lip on the back edge of the panel where it will attach to the X member’s extension, the one crossing under the center of the seats.  With a chunk of angle iron on the edge of the table, I measured and bent a 10mm 90° angle at the back edge of the Lamerant panel.  With the paper template fitted back to the strengthening reliefs on the Lamerant panel, I Sharpied around the edge of the template with a half inch of extra space for screwing up.  (Always plan on screwing up - fabrication 101.)

Oh, I did something that turned out to be prescient (SAT word, look it up): I marked on the X member extension where the strengthening relief bump sits in front of the driver side seat bracket, thinking it would help me line up the strengthening reliefs more accurately.  By damn, it helped!  Yeah, I was surprised too.




The template on the Lamerant panel
with the 90° lip at the back edge
Armed with two angle grinders, one with a cutting wheel, the other with a grinding wheel, I hacked into the Lamerant panel like I knew what I was doing.  I’m always a little nervous about cutting into a perfectly good chunk of metal, especially one for which I paid a decent chunk of change.  Damn the torpedoes…

I gave the first a generous margin for error, and I knew it wouldn’t fit.  By comparing it against the passenger’s side panel, I check the placement of the strengthening reliefs.  They were close and my goal was to get them even closer.  Like the back edge, the edge of the Lamerant panel against the lower driver’s door sill needed an up-turned 90° angle for welding.  I measured from the passenger side outside seat bracket to the passenger’s side lower door sill and compared it to my mark on the driver’s side and used the measurement to determine where to make the 90° lip.  I, of course, gave room for screwing up because it would be easy to adjust to take up some slack but a royal pain to add some.  Whaddaya know, later I had to take up a bit of slack to get the strengthening reliefs where I wanted them.  Who woulda thunk?

Hacking underway with room for screwing up

As with the template, the sheet metal went in and out of Alphie many times on its way to “fit”.  The trick is to GO SLOW!  When the panel was in Alphie, I would mark where it was striking the perimeter, against the transmission tunnel, the area under the pedals, the door sill side and so on.  I would grind down the marked areas and toss it back in the mark striking edges again.  Mark, grind, mark, grind as I slowly got the fit tighter.  At one point, I had to grind some areas inside Alphie, but it slowly took shape.

Menacing Edge - just looking can make you bleed

As you can tell in the pics, the “final” fit isn’t really final.  I will have some more precise fitting to do when I eventually weld in the panel.  I will also have some fabrication to cover some rust throughs and areas where the Lamerant panel and Alphie don’t quite meet.

Early in the fitting

That’s one of four floorboard panels…  Now, I just repeat the same procedure three more times.  Smashing!
