Possible Solution For Tracked Equiptment

[scalelover]

As I don't yet have any completed tracked equipment myself I'm not positive on the wear levels they actually produce to the tracks themselves. I'm noticing that quite a few of you guys seem to be worried about some aluminum being to soft for them, is changing from 6061 to 7075 going to be that much of a gain in the expected life span of the tracks? I know tensile strength is increased pretty well but if its from the edges of the gears digging in I'm not sure how much more it would help?

Only reason I'm asking is because price difference in materials will add up quickly from 6061 to 7075 or even 2024. If 6061 would work fine I have enough loose pieces I could probably make a few full sets for prototype testing

Could you guys fill me in on the life span expectancy as well as some ideas of the actual wear you see on your current tracks.

I agree, if doing aluminum 6061 is probably best bet. Depending on cost, I would probably opt for hard anodizing to get some wear resistance at least for the track pads. Not sure how my anodizer would like that many tiny parts if doing the links though.

Now if went carbon steel it should be pretty good for wear on the pads, and pretty easy to black oxide all the pieces for a good look.

If you get your design finalized and want a couple more prices ask Dan and I for quotes.

One thing I notice in the pic you posted of your design so far. I see a thicknees bump out in the links around the pad bolt holes. That will add to machining costs, more so than just making the whole link thicker. Same for what looks like a raised boss around where the pins go through, but it may be e-clips, hard to see for sure.
