I had about 34 bucks in the seal and bearings. The 6061 Aluminum was a drop. But I can buy 6061 for about 10 bucks a foot. I have a manual lathe so the Machineing is slow. So about 1/2 hr on mill so I come up with 60 buck total. I would need to make 5 or 6 of them to make it worth my time. So I guess if I could that some people that would take them for sure I would make them.
