JM, good guess .... its a good design as you can alter both table (cranked handle) and the head (Wheel), speed change is by gear wheels in the top of the head, and normal drilling done by use of the handle on the side (out of view in pic) to extend the spindle, only downside is the spindle is only (AFAIK) catered for the jacobs chuck, and not MT drills, but I can use MT drills in the Milling machine vertical head so not too worried.
It was only by accident I found it, I was at the time looking for screw cutting change wheels for my lathe.....but for £45 who could resist, didn't have the space ready for it at the time thats why the pic looks like its been abandoned as I had to hastily get in the workshop as I was back at work the next day and didn't want to leave it in the back of the van for a week..... When I think about it maybe thats the cause or start of my bad back ?
