Small boring and facing heads seem to be hard to come by as well. I think the 25 rt originally came with a 13" boring and facing head. The only boring and facing heads I have seen come up on eBay are either huge or ridiculously expensive. I guess this fall I need to get serious about finding one for my machine. If anyone knows the whereabouts of a small boring and facing head, in the 13" range, please let me know.

    I was going to do that for one of mine but traded machines instead. What I had in mind was about a 16" extension that bolts on, has the 40 taper machined in, and a drawbar with bevel gears.

    I think it would also be pretty feasible to make or buy something that uses quick change tooling to a MT5 spindle. I bought some MT5 emuge quick change tooling for that machine but never got around to trying it out. Saving it for a future radial arm drill.

    Boring & facing heads do seem to bring pretty big money. I havent needed one yet.

    I have wished I had one multiple times but have gotten by just manually adjusting the cutting tool with a dial indicator.

    A Wohlhaupter for under 12" bores, and a Bullard made the most sense to me.

    Better image for size.

    For whatever reason, the Autometric is a holy grail machine for me.

    I’ve always wanted a DeVlieg, my grandfather ran on for a time and spoke the world of them. Holding tenths or hogging.

    So I went to an auction to buy one. There were several. The 2B-36 with air lift table went for $4k, storage, rigging, and install at my shop another $1500.

    The 4B-72 with retrofit CNC control sold for $400.

    Both were running and shown at the auction.

    Shame,probably won’t have that opportunity again.
