DIY Epoxy composite gantry frame milling machine

Hi Lee
Would imagine for a peg spanner to align the cams prior to locking.

John ..
Your work is the best I have ever seen in small mills in 16 years from 5bears on up.

Hi All

Firstly I am remiss for not posting an update for a while. I am working on the gantry saddle and Z axis. I will post some photos soon.

The small holes are indeed for a pin spanner. very little pressure is needed as the friction on the CSK machine screw tends to push the cam against the rail base. If you study the photo you can see they are not in line although the bolt holes are.

The rollers are to allow the chip guard curtain, made from aluminium slat curtain or alternatively a piece of rubber, high temperature rubber to roll down at the front and back of he machine. You can see the curtain in place on the cad drawing on the first page of this post.

Regards
John

Hi All

Some good progress. The saddle and Z Axis has been cast and machined.
