Станок комбинированный металлорежущий СМ1720

Nice video. Makes me want to finally finish my cnc conversion I have a Shoptask Eldorado few years newer than yours

I have to give you proper recognition for making something akin to a silk purse out of a sow's ear. Well done, sir! Arduinos, no less !?! I foolishly (?) bought a 1720 XMTC GOLD in 1998. Even welded up a heavily triangulated 2 x 2 x 14 ga. steel stand fitted with expensive 5" industrial castors, independant leveling screws and pads, and 2 layer .70" cabinet grade thick plywood top with epoxy on the end grain, and covered with 1/8" aluminum plate. Designed cart/ stand to be fitted with ball bearing slide drawers and all, but never finished that part. Wanted steel for drawers, but only have wood working equipment. Fortunately, I scored basically several almost new top and bottom tool chests when a company I worked for closed their East cost operations, so all accessories had a good home with easy access. Anyway, don't know if I got lemon or such is just the nature of the beast, but the lathe ways are not even close to parallel. The tail stock gibs were adjusted for a nice sliding fit at the tail stock end, but was loose to the point of clunking as it was moved towards the lathe chuck. Same story for the carriage; adjust gibs near headstock and watch it lock up when moved towards the tail. Basically, it was pretty useless as delivered. If I had a large surface plate and a 60 degree precision straight edge, I might try scraping it in, but I do not possess the cool toys. Not worth sending out for a regrind, so not sure whether to MacGuyver something to tune it up or just sell it for whatever I can get and focus on dedicated 13 or 14 x 40 lathe and a large RF 45 type bench mill. Only problem there is space.....and money. I did replace the stock bearings with Timkens' on both lathe and mill spindles and that smoothed out that aspect, but without good ways, it is basically a glorified drill press and lathe with maybe 3" useful Z range. What to do, what to do? . Open to suggestions, constructive ones anyway. Too heavy to toss off a bridge.

Question So I have acquired shoptask 1720 and was trying to figure out how to reduce distance between the spindle and vice what is the type of tool holder you are using?
