Those look like Ph Horn. Adaptors occasionally come up for a realistic price.Had these mini boring bars a while. Making a holder, need a longer 2.5mm slotdrill

Had to use a 1mm carbide cutter to machine the little badge for a classic speedboat. Made from 316 and I bought 5 cutters as I reckoned I would snap quite a few, one did the job. Mind you if I had only bought one I reckon it would have snapped at the first ramp in

I had to make a new flame pipe for a large gas bbq, which meant drilling 300 holes in a length of 3/4" gun barrel pipe. I bought a box of 10 1/8" drill bits, thinking I'd need a few. One bit drilled all the holes, leaving me plenty of spares.

Had some issues trying to mill steel parting tool holder, and even fly cutting aluminium. One of my chinese SWT endmills is finally blunt and saddle lock needed adjusting
A bigger tool holder is more useful than a smaller tool, 14 opened to 16mm. Parting tool is 19mm so will take 3mm from that too.

What's the capacity of one of those when filled?

Tried milling the parting holder. New carbide endmill, took ages to remove just 1mm
So toolholder back in vice and took 2mm off the screw side. Now 18mm capacity instead of 14mm.
Milled a 100x100x40 alu lump square - will put a 40mm hole for mounting die grinder/vdi40 milling chuck. And a 120x60x30 lump of steel, it'll either become a cross slide mount or a toolholder.

I need to change my milling setup for less overhang. I will loose 25mm travel as the vice wont be able to drop below the cross slide/saddle and another 10-15mm if I use a mounting plate.
Option 1, drill two extra mounting holes in cross slide.
Option 2. Can move it even futher back if it doesnt cause bendyness and chatter.

Had hoped to finish the Panther gearbox repair on the big cnc by standing it on end,clocking one journal down and then using a boring head to finish machine the insert. Wasn’t to be as big cnc busy and I need to be in Singapore by Friday. So, onto the old cnc mill. Made the mother of all adjustable boring bars, 60mm diameter 800mm long. Angle head on the spindle, connected via chain coupling. Couple of 140mm Od x60mm Id guide bushes. Worked a charm...

I love how you make it sound so easy; "Mill was busy so I just whipped up a quick boring bar".
I don't suppose you want to take on an engineering student for an industrial placement...
I would love to,but unfortunately at the moment there are three people ahead of you in the queue
