10-01-2003, 11:21 PM
Got another question relating to tramming, read somewhere about using a brake rotor...good enough, but the only one that I have been able to aquire so far is an 11 inch jobby, and I can't true it on my 9 inch SB, soooooo, is there an automobile that uses smaller rotors, or what about something off of a murdersickle http://bbs.homeshopmachinist.net//biggrin.gif huh?

Jim, see if you can find one from a VW Gulf. I turned two for my uncle on my 9" S.M.

The rear rotor on my Passat is 9.5", so I imagine some of the smaller Japanese cars would have a rotor in the size you need.
I just did my brakes and replaced the rotors, if you want them, they're yours for shipping costs. You would have grind down to 9" or you could use your mill if you have a rotary table and bring them down to size for your lathe.

Tramming??? What are you building? I would use a grider to cut off the excess and then true it up. Wear a mask hoever, alot of dust to take off 1"

Maybe Geo Metro,or Ford festiva?
Did my in laws brakes on an 89 toyota Tercel...smallest car brakes I've ever seen.
If you are going to tram with them you should at least get new or cut the hubs out of some used ones and have them ground.
Edit#1: Duh...4 bright yellow smiley faces and I still didn't notice that you had already got your disks. Maybe you could get them surface ground at a vocational school...if you don't have access to a surface grinder.

Go for it Jim, I would love to open one of the magazines and find an artical by Jim Swanson. http://bbs.homeshopmachinist.net//cool.gif
May I suggest that if you are going to do that you may want to check with Neil before you post photos along that line on this forum. Awhile back Neil wrote in one of his editorials something about letting the cat out of the bag before the magazines came out. I will look for it in my back issues and get back to you.
