I'm in the process of building a mobile base for my PM3520A lathe. I've got somebody to do the welding. My job is to drill the 4 holes in the u-channel (3/16" thick), to bolt onto the feet of the 3520.
1) What would be the best type drill bit to use?
2) I need your fool proof ways to layout the holes in order for them to line up with the holes in the lathes feet after all is done? In order for my face not to look like this...
3) Oh, and would you drill the holes before the stretchers are welded to the u-channel, or afterward? I think it would be easier for me to drill afterward, so as to get the holes in the correct location, but it would be heavier to try to drill on the drillpress. So that's why I'm counting on your ideas! Thanks,
W.C.
