The first task on receiving this is to get it mounted. I had a bench grinder pedestal made with a bigger/thicker upright and bolted it to concrete with 8mm thread dynabolts. Then had to drill the top plate to fit - its not mounted squarely, but that's ok. Bent my first tube. All good. I am working my way up to 1” tube (at 7/8” now). You get a mark on the tube at the tube retainer. I have tried to put shim steel in to buffer the tube, it still marked, but not as deep. I have some 3mm leather to try, but will have to swap the retainer off the next size up die, and with 1” tube I wont have a next size. The only features I would like would be a carry case (i have seen other vendors with a case, but it doubles the price) and an angle pointer for repeatability when bending more tubes the same. My best suggestion is get extra tubing and practice before making your final parts.
