I went to the Dunstable Downs amateur radio car boot sale today.
As usual I was looking for TE but came back with mostly mechanical engineering bits.
Find of the day was a Pultra precision lathe. I think it's a 1750 but have to check. Certainly 50mm center height. These are small machines, I can pick it up with one hand. It is in fair condition and came with a lever action tailstock, 3 and 4 jaw chucks. No tool rest or slides though. The slides are probably the easiest parts for me to make myself. I have some miniature linear rail bearings that would be ideal. The same donor unit that hs the bearings, an optical scanner, also has some leadscrews. I will have to check them out. Not sure when I’ll get a chance to investigate the further, got a couple of busy weeks coming up. Other purchases included a unknown high speed precision PCB drill press. It is older and very well made. Direct drive from a universal (brushed) motor with the whole assembly sliding in a plain bearing about 2” in diameter. Needs a clean but looks OK. I’ve wanted a drill of this type for years. The universal motor will make it easy to add variable speed control.
Small items were a small Verdict lever DTI in the case with fittings, M&W depth micrometer and a small V block.
Cost was minimal, £40 for the Pultra, £10 for the drill and £4 for the smalls. smiley
I did get a few items of test equipment too. A Telequipment C3 'scope calibrator £1, an Advance OFS 2B off-air frequency standard from TGGZZ (need to check if this is 198kHz or 200), a mechanism digital force gauge, 10GHz Doppler speed detector (vintage and free) and a couple of bits from a friend.
