I am trying to figure out the purpose of the vertical blue sheet. The bottom one is to trap waste I assumed, but I can't think of a use for the vertical one.
I think they are to keep his leadscrews/guides clear of chaff. mine get fowled easily.
yep - those sheets roll and unroll. We used car seat belt mechanisms to do it. I will be taking parts down for painting today and will take few pics of them and post them tonight.
The mill is designed to work with water cooling and as the linear guides (and screws) are not stainless they get rust easily. Also hate to clean constantly debris from the mechanisma (as I had to do on my previous mill)- sooo we decided to close everything.
I am proud to show you the finished mill ... well almost - the spindle is missing - it is in the process of making. Everything else is ready. I've almost finished the electronics but the school is coming soo progress will be slow from now on.
Patric - here is the assembly of the belt rollers. Nothing special - just two seatbealt mechanisms, halfway cut and fixed inside a PVC pipe - but you have to make sure that one is from the driver's side and one is from passenger's side because that way you can use both in the opposite ends of the tube (they are "mirrored" - I used from Fiat Tipo)
it is the winter break now and it is time to get back on the project First things first we've got the spindle finished. It has dual tapered roller bearings with a tightening nut (to adjust the "backlash" of the spindle).
It is forced oil cooled/lubricated. Here are the pics and the CAD model.
Have in mind that all the parts are made from scratch (except the gear wheel and oil connectors).
Please excuse the bad quality - I only had cell phone on hand.
