If you can stretch to it then get a variable speed one, as mine is fixed - if you put a large cutter in there it spins too fast and burns it out.
I made a pillar drill mount, used a bench mounted pillar drill, cut the top bit off and welded on a lump of channel, job done. Trying to work out how to put some pics up!
Pics would be great - just click "upload file" under the post box and navigate to the picture on your pc - then choose thumbnail or full size - pretty simple really no need to resize etc thats all done automatically for you here
Found one on my phone
