make it what ever size ya want and cut nylon bushings for it.
k. use brass then... your rig...
Pat uses DOM. 120 wall. The only stress on the tube is going to be where it mounts to the frame or tube frame. I haven't seen any break with .120 wall so .188 should be good. Never can go wrong with over building it.
OK, To continue on....I could source some Nylon...But i HAVE some fm brass...Maybee a better mouse trap? But really only a thought at this point.
This is what i was looking for..Thanks. Now someone tell me why using brass for the end bushings is a bad idea. Im mainly concerned with it getting wallowed out/oblong or making noise.
There's no reason you couldn't drill and tap the brass for a zirk fitting. Hell, you probably could even machine into the brass a little ring all the way around the inside to allow grease to 'flow', giving an even distribution. Should be pretty easy to do with a lathe.I would think the brass would wear away. With the nylon inserts you can add a little grease and it'll damn near last for ever.
