Hbm tooling

[lobust]

I would put a nice quality DRO at the top of the list. Way before changing the spindle taper.

My 6 HBM requirements were 1) built in rotary 2) DRO 3) 50 taper 4) one piece base 5) power clamping 6) tailstock

I would sure like a facing slide, but haven't found one for a good price yet.

I bought mine for what I thought was a good deal considering the rigging situation was pretty f'd. There was a 60' deep vertical X-ray pit between my machine and the door. Had to take it out a narrow alleyway door with some tricky rigging.

A couple years later I could have bought a premo condition Wotan CNC HBM about the same size with rotary and tooling for about 1/2 what I paid for my manual Kuraki. The Wotan was in a shallow pit for coolant containment though. I think it would have been a real tricky bit of rigging to get it out. It also did not have a tailstock.

Yeah, I skipped over a DRO I admit, pretty much goes without saying that's the number one upgrade. If you can get a 50 taper with power drawbar, then that's good. Otherwise though, the Capto is a huge timesaver over any other kind of manual release system. You could go all in and do hydraulic eject capto...

We used to have a big Staveley-Richards with a 50 taper power drawbar, but the mechanism was finnicky and had weird bayonet-cross pull studs.
It was a 2.3m cubed working envelope machine, pretty much the biggest table type borer I've come across. 1970's machine, lots of hydraulics and electromagnetic clutches, it was a maintenance nightmare. It went in a container to India when we'd had enough of it.

I could really use a cnc borer with around a 1.5m cube work envelope. Been on the lookout for the last few years but no bargains have presented themselves.

I have passed up on some super nice manuals that I would have loved to have on the floor, but the reality is that manual boring work is just way too much of a time sink.

after getting this taken apart and out of phils shop I have a whole new respect for riggers the heaviest piece was only 21000 but with all the power lines in the ally I was amazed a crane operator would load it. I can see why those huge ones on gsa are no bid or pennys on the actual worth.
they are going to have 10 of thousands in professional rigger fees
I looked at renting a landoll to get it like you have mentioned garwood but the nearest rental one was salt lake

I made a key by making a sliding angle with a screw that pulls the two angles together to lock the Morse Taper. Works well. I’ll try and get a picture.
