Another homemade milling machine
shipto:
Busy weekend not just with the mill but found time to get some things sorted I bored out the old bearing housing and added it as support for the bottom of the column also opened out the origional holes and tapped them to M10 so it should be secure enough. I have the handle for the screw located at the top for now which will be a pain in the backside to use but one of the first jobs once table is finished will be to make a couple of bevel gears with a 2.5:1 ratio to match the M20 screw. I am pleased to say however that it seems to work well with the screw inside the column sorry pic is a bit dark.
On the subject of the table I got a temporary end plate made so I can use it to start milling the bits for the table and in the meantime I need to find a local tin basher to make a tray.

Realised tonight while drilling holes for bed parts there is a bonus to having the screw inside the column :D I can rotate the knee and reach past the end of the table, not sure I will ever have a use for the capability but still.

I am really happy with it now, started to mill for the T slots and apart from a little mishap where I hadnt locked the rotation up it cuts lovely
shipto:
Have two of the three parts for the bed milled now, it did show up a problem for me to fix under the bed casting the nut is trapped and was held in place with a m4 grub screw which turned out not to be man enough for the job so it was replaced with two m6 grub screws one to hold and another to lock. I suspect that the X/Y table will not last too long guess I better put a axminster or similar one on my Christmas list.
shipto:
Table is together and hopefully tray is in hand very soon. Replaced the gib screws on the X axis from 4mm to 5mm and put a bit of scrap aluminium on it to test the squareness of the X to Y and I think it is slightly out but not too much that I cant fix when it becomes a problem.
