So the Delrin experiment went well! My parts were so thin and Delrin so soft that the pieces got deformed by the vice, but over-all it worked as expected. Time to graduate to Aluminium!
What do you know? A beauty, isn’t it?
Unfortunately, the tolerances were off and the bearing didn’t fit the first time, but that was an easy fix.
Also, I milled two pieces, but learned about peck drilling the hard way. If you try to drill a 2.5mm hole 25mm deep in one go you break your drill…. So now I know. For those who do not know, peck drilling means that you drill a few mm at the time and then pull the drill out to clear out all of the removed material and reapply alchohol mist for lubrication before going down again.
