I made these quite a few years ago. They work okay but can be a little fussy. Three point adjustability to correct for notoriously uneven concrete floor is handy and I used to have bigger Nylatron rollers but I scavenged them for reuse already so the brass tubes are a half-baked substitute. Although not clearly shown in the photo, the vertical columns are biased about five degrees toward the long leg so they’re not quite as tippy as they look.
Vertical height adjustment on the column in increments of about half an inch using staggered holes and hitch pins. The wire basket is nice for catching off cuts if I’m doing a lot of multiples but in reality doesn’t get used much. I think I’ll phase these out and go with a ballasted monolithic base but for now they still do the job and nest into a fairly small footprint when not in use.
