Need some machining - August 15, 2013, 08:13 AM

I'd like to get stainless steel copies made of the aluminum chain adjuster blocks for my KX. They are very simple, basically like the pic below but without the recessed section around the axle holes. Before I hit up a local machine shop can anyone here help me out? I could probably make sturdier ones myself out of some really hard wood (lignum vitae) but probably should stick to metal.

I would like to help but I am super busy right now. Also you do know that using stainless will cause corrosion on the swing arm due to dissimilar metals. I have done this for others and without proper care the block can cause the swingarm to get ugly.

Why do you want stainless?

I'm with dodge on this, Al would be a better choice. Is there something wrong with the ones you have?

I have 3 sets: 1 chewed up set that came on the bike; 1 chewed up set that came with a replacement axle I bought off ebay (original axle was messed up where it mated with the bearings); and a new set I just bought, now chewed up. I thought I was being careful when I put the wheel on last time, I cleaned up the axle, checked it over good, greased it, etc. When I went to pull it off I turned the nut and it spun easily enough. Then I realized the whole axle was spinning. So, now I chewed one up myself.

There's a slight gap between the axle flange and the block. Maybe if the flange fit more tightly against the block it would keep the axle from spinning. Or maybe if the block mated with the flange on both sides, like this one:

Sounds like OP isn't happy with the quality of the AL ones, but since I don't know shit, I'll just agree with Dodge because what he said makes sense to me.

EDIT: well OP beat me to it..

yep, 2 flanges and they should be a tighter fit.

Sounds like all you need to to have a tighter tolerance on your next set of blocks, which means you should be able to stick with aluminum.

Yeah, if it was a tighter fit AL would be fine, particularly if it was held on 2 sides. Shoot, I could probably make one out of AL using my woodworking stuff (carbide). I understand that makes a LOT of chips though.

There is an ebay seller in Glen Burnie (I think) that sells all different kinds of AL up to like 6" thick.

I'll check out those sources for raw AL. Thanks!

Check out the Ride Engineering blocks, they are much better than factory.

Yeah, unfortunately everything that's out now is for the 03+ bikes with the 25mm axles. The earlier bikes all the way back to at least the 94 (mine is a 00) were 20mm. Pro Circuit still has them listed on their website but as "back ordered". I sent them an email asking if they're really back ordered or if they'll ever produce them again. I bet not. It is a simple thing to make if you're not trying to make them all pretty. I could make a set out of wood in 10 minutes.
