80/20 frame Material Questions

[DonRotolo]

We also cut Item (a competitor of 80/20) with a miter saw, it works fine with a carbide blade and some care.

80/20 is perfect for places that might need adjustability, but awful for places subject to shock loads. For example, our entire frame was made of 80/20 (Item really, but for the sake of discussion they are the same), the top parts that held the shooter, conveyor and ball basket were great, we could move members around to tweak things. Our lower frame, however, was a problem with it constantly shifting and loosening, even with bumpers, because of the beating we took (and gave) on defense.

I would think that a kitbot frame below with 80/20 everywhere else would be a good choice. Just remember that 80/20 is heavy - not heavy for its strength, but the strength may be far in excess of what is needed for some applications. In other words, don't be afraid to use some angle or U channel where it makes sense.

If you guys are interested in 80/20, I STRONGLY advise you to call the local 80/20 rep, have him come in and talk about it. These guys are experts, and can really help a lot - and they are very happy to do so. I know the guy for up here in bergen county, so if you need help finding the guy for your area, PM me.
