Re: brass nut alignment?

Re: Screwless vise
I mounted my non tilting version on a flat base that is wider than the vise. This allows the use of standard T-slot clamps to secure it anywhere needed. Often the clamps will be where you need to

Re: Who to install hand wheel bearings?
I installed a pair of 8mm x 22mm bearings on my handwheel shaft. Unlike most others, I put both bearings in front, with nothing in the rear. This has worked very well for me. See my post at:
