Thread: Followed Me Home II

After getting the wheels painted, which is, by the way a most humbling experience, I've decided a "process improvement" is needed on the spray booth that will accomplish two things. First, the I found that with the fan louvers tending to push the exhausted paint laden air downward and the filters located beneath the garage doors on either side in addition to dust in the air my air filters are catching a lot of paint dust. Here's a filter after about an hour of spraying, all in.

I had initially thought that I would convert the screen door in that folding wall into a "filter door", but then I realized that I can very easily simply cut down my existing filter banks to fit inside the folding wall sections, staple the plastic to the frame and cut away the plastic over the filter area. That way the fan will be sucking air through the barn, which will tend to drop out ambient dust & spores, and exhaust on the other side. The other bigger benefit is that I won't have to horse around the filter banks and seal around the openings any more. Not as good as a down draft, but good enough for a temporary spray booth!!

Here's the wheels done, shot indoors which puts a darker caste on them...

and here's one outside in the sunshine.

Not perfect by any means, but they'll do for now. Got 'em out baking in the sunshine today, so they'll be ready to accept some tires in the coming week.

I lost too much of my Saturday going to the new house under construction for one of my boys and his bride, so the differential still awaits it's new color. The new gears are all bolted in, and it's a good thing I changed them out because the 3.00's were pretty badly surface rusted from sitting in an unheated garage for five years, and my buddy tells me that the minor imperfections caused by surface rust will become stress concentrations in use, and lead to premature failure. I never knew that tidbit before!

Wheels came out real nice Roger. I like the color, big difference in the sunlight!

Great color choice Roger

Nice color choice on the wheels Roger, and nice painting setup!

i like the colour as well-any progress is still progress!!

Just stopped by and scanned through the build photos. Thanks for sharing. How close are you to being on the road or are you already? Never mind I saw it in one of the recent bad weekend photos...

I've been a bit hesitant to post much, as the atmosphere around here hasn't been the best lately, but I took a step today that might help someone else who's scratching their head about fitment. When Mike (34_40) was here last week we set the new Rootleib hood in place and the fit sucked. With the cowl to grill distance set and fixed the hood simply did not fit at all. We had a significant gap at the cowl, top tight, bottom out by over an inch which points to the grill being too high.

This one shows that the gap is nominal 1.25"

I sent a couple of pictures to Don (DA34GUY), as he's probably fit more deuce hoods than just about anyone around here, and he agreed with my assessment. The radiator and grill shell both seem to be OK, so the only thing to do is drop the mounts on the frame. The firewall to radiator braces, with their upward arc, also point to a problem with the radiator being high.

Here's the mounting tabs.

So I cut off the tabs, clamped some angle iron pieces to the frame to support the radiator, and started the drop. It's looking like the radiator is going to end up right at 1.25" lower in order to have the hood aligned. One key point is to look at the alignment of the body side molding to the hood side molding, and that they are in a nice, straight line.

Tomorrow I will be back, fine tuning the location of the radiator mounting tabs to try to get the placement perfect for hood alignment, then weld them back in place and move on to steering u-joints.

The other thing that Mike and I discussed was that with the R&P the angles get bad fast between the rack shaft and the steering column. Mike mentioned that he had opted for a double u-joint at the mid-point, and I assured him that I thought my single would work, but after some measuring and rough in the center joint is more than a 35 degree angle, so I've ordered a double U, too. Thanks a lot, Mike!!

Glad to have helped in any way.. one other thing on the double joint. You'll probably find the steering "speeds up" / "slows down" as you turn the steering wheel, don't forget the "phasing" and you'll maybe decide to double up the double u-joint to help that condition.

I don't find the condition offensive and only rarely notice it. But it is there.

Looks like ya got it figured out now Roger, yer on the right track.

Nice fix Roger. Your making some major progress. Keep posting, we will filter out and un-needed advice!

Roger, it's nice to see you posting progress on this one. Nice work repairing your hood. I think I'll have to step up to some double u joint joints for my steering shaft because I want to set my engine lower in the chassis. They sure aren't cheap. Oh wait, what is?

Heck, that was a large gap to fill when you first started but you have managed to pull it all into a nice line. I was going to suggest packing the front of the body a wee bit so that the grille / radiaator didn't have to go down too much but you have gained the space you needed without doing that.
Mike, I'm not fimaliar with " speeding up, slowing down "of the steering when two flex joints are used, can you please explain the why and what fors behind that and how noticeable it can be ? I know the on some builds one can't avoid not using universals in the steering but honestly didn't realize that doing so can effect the steer " feel " of the car.

Whip, have you seen any of the threads regarding u-joints in driveshafts? Are you familiar with "phasing"?

If you have a joint out of phase the shafts have to "speed up" / "slow down" as they rotate, steering gear or driveshaft no matter, you can actually feel it in the car.

When you add a double joint into the mix you must be very careful with the phase cycle...

If you google U-Joint phasing, there are many good videos and write-ups..

This is one of the best graphic representations of the speed up/slow down issue with driveline u-joints - https://www.youtube.com/watch?v=DDmz0tibVGM

I can see that it applies to steering u-joints too, but I believe that the impact of it is not really much of an issue in the steering geometry since the speed up/slow down would only be seen in a rapid multi-turn maneuver. It's a real problem with your driveline.
