I don't understand why we have to pay $35 for a flange for the cheap ballnuts. I see this come up frequently in the forums. They won't even fit into my small design, therefore, I was forced to buy the 15/16"-16tpi tap. Ok, so now I am going to tap 3 holes and there it sits doing nothing while others thrash around trying to save a buck. This isn't a business proposition and I am sure a rent-a-tap idea won't work, but as a member of this community, I would like to help others take advantage of the cheap ballscrew scenario. I think I could make plain round aluminum flanges with a threaded hole for maybe $10? If I do it in steel, the tap won't last long. The ballnut has to be pinned anyway, so who cares! Mr. Moderator, it's up to you.
