Thanks Bill, did a bit more to the bench. I fancied one of the dovetailed mounting plates for bench pegs and other fixtures. They tend to be pricey, aimed at the jewellery trade, and since I haven't 3D printed anything daft in a while....
Another adHoc build, I made the standoffs too long. I modelled the printed plate on the commercial ones for holes centres, just in case. Test fit of the parts on the bench and work out positioning, at this point I made a hash of drilling the holes in my pallet scrounged timber, the drill bit developed a mind of its own. The idea of mounting the plate just on the standoffs was abandoned as they would just sink into the wood. I pulled out some really scabby alloy plate, cut and drilled then tarted it up with some emery cloth wrapped in beer can, in the chuck on the drill press. It looks a lot better than what I started with.
I thought long and hard (about 10 seconds) on my mounting bolts. On hand were M10 high tensile bolts and flanged nuts, will they really handle the load of needle filing and detailed work ??? Slap some glue on the off cut of oak floor used for the backing plate, she'll be right....
I made the mistake of sitting back to admire my work, when the Boss arrived and appropriated the bench... The glue hasn't even dried yet !!!!
Now I commented about needing maybe one extra saw stand, maybe I should bulk buy. The plate will take a bench peg and also a Dremel or Foredom tool, that way the tool is stationary and you move the work about. Custom fixtures can be 3D printed or laser cut for delicate work at the bench. Maybe I will get back to the little engine when the Boss has finished.
