Reaming torsion bars

McInturff Racing · 1/10/12, 5:25 PM

Anyone have any good ideas for reaming out torsion bar bushings that doesn't involve buying a $180 reamer? My bars are just a bit too tight with the new bushings (nylon) and I have a couple ideas but having never done this before I don't want to screw anything up. Just because a small sanding drum or dremmel tool seems like a good idea to me doesn't mean it is and I would rather learn from other people's errors than make my own whenever possible.

You could use a small sanding drum, but use it in a cordless drill, not a hi-speed Dremel, and probably get it loosened up, I have reamers for that purpose, and they can be bought for a lot less than the number you put out, Enco, a machine tool co, with internet showrooms, will have what you need. I don't like nylon, for that reason, hard to hold any tollerance with it, but you don't really need to lube it much either, I used a lubed bushing, in the cars I built, the material was impregnated with the lube. Might try just slowly working the bar in, and turning it while you do, it may align itself, and for sure, will loosen up, in a few laps. Bob!

Or, you can take a sharp knife, and scrape them to size, that'd probably be the easiest, and safest!

We run sprint car and I use a 1 1/8 " spade bit and it does a good job remember loose is better than tight
