That barrow has come up a treat.
Nope. Just for the drill. I wouldn't use a mitre saw in the workshop if my life depended upon it.

They're the untidiest of machines which resist any & all attempts at dust/chip collection, IMO. I don't use woodworking powertools in the workshop unless I must, due to dust extraction/collection requirements. There's a fine layer of wood dust on everything just from using hand tools recently in there, so it'd be a dive if I'd been using power tools.

I rarely clamp anything on the drill, so the supports are just there to make it easier when holding longer pieces in place by hand. For example, this weekend I had to drill some holes in a uPVC infill panel, (so that I could cut some vent holes for louvre vents with the jigsaw). At over two feet long, it would have been awkward without the supports.
Before anyone mentions any danger from doing that, (holding things by hand on the drill),

the pillar drill has a round leather belt driving it, set with minimal necessary tension. I can readily make the belt slip via hand pressure alone.
