[Henry James the 47th]

By the end of the day, I had both outer rockers tacked in place and was feeling pretty exhausted. I hope to have the LHD firewall into place tomorrow, along with the inner rockers (which will be a pain to fit into place) and fingers are crossed that this will come out the way I am intending. There are a lot of unknowns as far as the effects of shrinkage and possible warping that make me a little nervous about the result. You can see the end of the rocker where it joins to the door post at the front wanting to twist a little outwards in the photo below, and i don't think it is a significant issue at this point.

very nice work.

very nice work.

Thanks Mike - I wouldn't have even attempted this if it weren't seeing other people doing the same thing here on the forum in various build threads.

 

[DanS HJ-45]

Beautiful indeed. You are flying through that bodywork.

What kind of primer are you using there? Rattle can, or something more elaborate?

Dan

 

[Henry James the 47th]

Ah yes the primer...so far I've been using rattle can Pro Form etching primer and primer surfacer. For the sheet metal, this is more or less just to protect bare metal from rust - it's convenient and quick. My plan is to use PPG 2-part epoxy primer on alll of the sheet metal when I'm done with the patching work.

Then I'll do the underside of the cab and fenders, cab footwell, and the underside of the bonnet with spray-on bed liner, either SEM or PPG brand. The Stutz gun for spraying bed liner/undercoat is only about $30, so this seems worth doing myself, though I was considering having it Line-X'ed at one point.

I've been pondering the primer situation with mine... I want to paint it myself (lookout!), but not real sure how to get from the working on it in bits and pieces stage to a fully primered vehicle. I was planning on setting up a little tent inside the shop to do the primer/paint, but that's a bit cumbersome and I would only want to have that erected for a week or two.

I'm almost tempted to rattle can it for protection, and then to clean it all back down to bare metal just ot put the final (good) goat of primer on. Am I overthinking this? Or should I just use the good primer the first time and call it good? Are you going to remove the rattle can primer, or just put the good stuff on top of it?

Well I'm far from an expert in anything auto-related, but I was thinking that since etching primer bonded really well with the bare metal, that I could apply the epoxy primer to it directly (assuming it is clean), and call it good. I imagine bare metal is best of course, though I'm not worried about putting epoxy primer on top of etching primer. So long as they bond well to each other, that's the main thing.

A long day on the truck today, and made some good progress. Started with the inner rocker on the passenger side, which was not the most fun piece of cut out.

 

[Henry James the 47th]

It took a while to hack out the remnant of the firewall door pillar, then, after tacking the inner rocker in place, I decided to take a look at how the LHD firewall would fit. I was getting nervous about metal warp at that point. As you can see, the firewall stiffeners are not in identical alignment for LHD/RHD firewalls

 

[Henry James the 47th]

I marked the location of the stiffeners, removed the firewall and drilled some holes for spot welds

 

[Henry James the 47th]

Then I chopped out the inner driver's side rocker, but chose not to tack it into place quite yet. I put the LHD firewall back on, and then used a little persuasion to adjust the outer passenger rocker panel into plane with the door pillar. Then I started fabricating the lower ends of the door pillars, doing the detail slightly differently than factory by bending little tabs onto the bottom which I will weld to the floor pan.

 

[Henry James the 47th]

Welded up the ends of the door pillar lower sections, did a couple more trial fits of the firewall and made the necessary adjustments to get everything where it should be. The bolt holes from my jig lined up perfectly with the new firewall!

 

[Henry James the 47th]

and at that point, the moment had come: I welded in the firewall and Henry James is now LHD

I have lots of welding still to do on the cab, not to mention the upper cab window and one of the doors, but it felt like a milestone in this project to finally have the cab converted.

I'll be taking tomorrow off.

Fantastic sir! And here I was thinking that you were saving the firewall swap for the weekend. Impressive to the max!

Dan

 

[Henry James the 47th]

I'm grateful for your comments Dan. I wasn't sure if I'd get the firewall in place today, and I'm sure glad I could make it happen. From now on out, when I stare at the cab I see a cab I will one day sit in and drive, not a cab that needs to have its firewall chopped off. That's sweet.

doing a great job on your 45 especially with the bodywork, i cant believe how fast its coming along! cant wait for more pics

Henry,
check out Color Your World for the 2 part primer, down by the credit union. A friend of mine used it on his 85 GMC rstoration and had very good results. It was cheaper and is an industrial application, tough as nails when set up! Should be compatible with other brands for when you do the top coat. It maybe just a little easier on the pocket book without a decrease in quality.
If you see the truck out and about it is a Viper blue diesel short box 4x4, guys name is Blair. I am sure he would give you a very honest and properevaluation of the primer.

Thanks for the tip Bob - I'll check that product out.

Well, thanks! I think I've got a long way to go on the body work, and have to go over some of my earlier welds and repair numerous small burn-through holes. That situation is getting better though as I get the hang of welding 16g. sheet. I stopped using the copper backing plate. I found it worked well for a single spot here and there, but if you did too many spots on the same plate, it would become a bit of a heat sink and make burn through more likely. Probably the biggest lesson so far in welding has been not to try and do too much too fast. Now that i can see better with the auto helmet, and my technique has improved, I think, and I've found that I can increase the heat and wire feed without problems. Before I was welding at heat setting 2 (on a scale to 6), with a feed speed of about 20~25; now I weld sheet at heat setting 3, and use a feed speed of 30. I'm thinking i could bump the feed speed up a little further. I'm still learning.

It would be nice to have finely variable heat settings on a welder, as it seems like a setting of 2.5 or so, in this case, would be about perfect. I guess when you buy the expensive welders, thats the sort of stuff you pay for. I'm feeling really fortunate in this case that John at E4 has been willing to let me borrow his small Mig welder. The cruiser has sucked up so much cash that I really couldn't afford to buy one, and if not for the current fortuitous arrangement, I would be waiting a while before i could get the welding moved along.

Once you can weld, you start looking at metal in a whole different light

Started my work on the truck today by heading to the wrecking yard, where I obtained a set of mini-truck knuckles, aisin hub selectors, a 60 series steering column, and a pile of nuts and bolts, plugs, and a couple of electrical parts.

Got back to the truck and set about slicing the knuckles apart for the last 1" to produce a ring with the disc brake tabs. Then I ground them somewhat flat along the cut line and media blasted them.

Then I went to see how they might fit to the axle flanges, and it was a bit discouraging. The backside of the flange has a raised lip on it that is larger than the diameter of the knuckle section, so I would have to get them machined, and I know already that the diameter of that inner raised lip is 4.75" and that it sticks out from the back of the flange about 3/16ths. The bolt circles are different in diameter as well, and after machining a rebate into the knuckle section, there wouldn't be much meat left. Back to the drawing board...

While i had the blaster going, i cleaned off the brake line mounts on an 60 series front axle I had, and then chopped them off. Then I cut the mounts for the lines off my 47 front axle and welded the 60 series bits into place.
