Scratchbuilding U-joints ?

[southside johnnie]

Hello, all...I am new to this forum.I have recently returned to the hobby after an absence of about 25 years.
I was wondering if any of you out there have any experience\ideas to share concerning the scratchbuilding of universal joints in 1\24 scale, or have any info regarding where aftermarket u-joints might be found?
I appreciate any input.

Unfortunately, if people are unable to answer your question, they are unlikely to post, it is the way a forum works.

I am certain you'd find it equally frustrating to come here and see 10 or 20 posts saying 'I don't know' too.

Sorry that we're unable to answer this question for you.

Check www.scaleracecars.com for u-joints. I am sure I have seen them there, but I'm not sure if they were 1:24 or 1:43. Scratchbuilding would be straightforward, but difficult because of the very small size. I don't know if metal or plastic would be better in the long run, but I would make them from plastic because I am more familiar with it (and have no idea how to do metal). I would use some styrene rod of the appropriate size (I'd probably eyeball it, but you might be better off measuring and doin' up right). I'd cut two lengths of the rod a little larger than the diameter of the u-joint. One length I would cut in half so it was two half lengths. Then I would have styrene tube the size of the knuckle, and I would cut it in half so I had some half-circles. I would then carve it to a pie shape like the knuckle of the 1:1, and drill a hole through the tips (make two). Then I would guide one length of rod through one of the knuckles, then, tape it down. I would tape the other knuckle in place right next to it, and in the correct position. I would carefully thread the half lengths through the holes in the knuckle to the whole length that goes through the first, and glue it in place. This would be very delicate, but very exact and poseable. I know that is confusing, so here is a picture:



Note: I've never done that, it's just conjecture. You could just as well go scrounge some u-joints off of an old kit with a separate molded driveshaft.

I am about to start machining the U-Joints for our drag racing drivetrain parts but I don't know if you could use them or not. Our driveshaft will be customizable; separate U-Joint assemblies and driveshaft.

PSF hobbies has them. They are made by R&D unique who also has a web site, but I have done business with PSF for years and have always been treated vey well. They also have a big selection of other parts as well.
Here's a link to the page. The u-joints are cast in white metal as I remember.
