I perhaps fed too fast, did not take the time to center drill or something - dunno, but most frustrating. Any hints or pitfalls to avoid when drilling in HDPE? My bit was sharp and I was holding everything very square. It is tricky stuff to deal with I find.
I cleaned the pipe rails last night and once the Z axis nuts are dealt with I will assemble the gantry. I forgot the 1/2" bearings and ordered them last night. This should come together in the next 2 weeks as all the difficult stuff is done. |
