    Good idea about the ER collet shanks. I made a brushless spindle recently from a 100mm ER20 straight shank. I guess i could get a really beefy ones like ER32. The thing will be getting the tension on the material?

    I used HTD 5M belts on the cnc build so happy to use them again, even have some spare idlers.
