Thread: drop spindles on straight axle

Tweet

Have some pics of this project up in my journal over to Hotrodders.com.

Strange post bone.

Not so strange if your curious about what the title says. Take a look at the journal.

That was just a quick reply. Here's whats happening.
Building a 25 dodge bucket from parts and pieces I have left from other projects. Using the front half of a 25 Dodge phaeton and grafting it to a 32 Lasalle cowl for body.That is to make room for my size 13s. Cowl was sectioned and body widened 5 " to fit. Will probably end up as a RPU. Overall height at 44" with 8 " clearance.
Most all other parts are 61 pontiac on a fabbed 2x3 frame with 100" wheel base.
I adapted the 61 steering knuckles to a 47 Ford axle so I can use the 8 lugs on the front. See pics. See journal at Hotrodders for for process. In spite of all the static I got on the hamb, the job is done and I believe it is going to work well. Will use 61 pont centerlink power steering. Don't think it needs power but that's what I got. Suspension will be 4 link on torsion bars. 52 Buick lever action shocks control everything. Pics coming when further along.
Rad shroud is also 61 Pont. Been turned, sectioned and grafted. Took pieces from 2 cars. May modify to use the 61 headlights and bezels instead of the king bees.

Still need driver quality hood brow trim to finish.

Motor is 61 tripower 389 348 hp backed up with a cast iron t10. Drives a 3.70 posi.
Out back, a pair of 61 Bonneville lights turned on end will do the warning duties.
Go juice supplied from a 1950 Olympia 15 1/2 gal. keg

Gotta say, you are definitely coloring outside the lines. Nice metal work on the spindles, but I wonder what the safety guys are gonna say about them.

What I meant was, when someone wants you to look at something, they normally provide a link.....like this.....

This spindle adaptation isn't all that much different than the one I did on the T, using '75 Lincoln spindles, changed from rear steer to front steer for use with a MII R&P. Looks like nice work to me.

Puts the tire out a long way, your "Scrub" is going to be out of whack. Not as important as many engineers think, but something to consider.

Tech
You have to remember I have a computer conundrum. My daughter posts pics for me. If you want a link, I can get one from a 6" chain i have for you I can run a slide rule
(remember those?) but computers kick mine on a regular basis.

Mr. Pope
The scrub was of some concern when I started this. Mockup showed about 7/8" but reality came in at 1 1/16" which I feel is acceptable. In light of the fact that the 2500 lb car will have power steering, any adverse steering action that may cause should be negated. I remember driving some of the 70s vans that had huge offsets, some so bad it took the wheel bearings out on a regular basis. We're talking scrub radiuses of 4-5". They didn't have steering traits that were attributle to that, mostly roll center problems.

looks like 7 or 8 inches on my moniter

Hope this doesn't hijack the thread... but i have to ask... (my ignorance is showing) What do you mean by "scrub" and what does it affect?

Scrub, or steering offset is the difference measured at the ground between a line drawn vertically through the center of the wheel/tire and a line drawn through the king pin axis with the vehicle viewed from the front or rear. If the wheel/tire centerline is outboard of the line drawn through the king pin axis, as bone has done here, positive offset is achieved. If the wheel/tire centerline is inboard of the line drawn through the king pin axis, negative offset is achieved. Ideally these lines will intersect at the ground under the center of the tire as viewed from the front or rear of the car.

Excellent description, I was able to get an image in my mind of what you are saying. Thanks, I learned something today.

not me. I may need a picture to fully comprehend the technical aspect of SCRUB.

well without a picture--can you visualize the king pin intersecting the cl of the tire wheel at the middle of the contact patch?
