I like the video, but I need to add a comment about using marker pen as an indicator, it does not work, I tried it first as it is much cleaner way to go, but indicated a ring like yours and not much else, so I got out my tin of engineers blue and got mucky, just a little on the tip of my finger and wiped off to a very thin coat, and I straight away got a good all over clean contact over the entire Jacobs taper. VERY satisfactory result. Now about to try the heat treatment to get an interference fit, worry about getting it apart at a later date.

I agree, the marker pen only just gets the job done and you have to lay it on thick. It was enough for me though and 8 years later the chuck hasn't come off again yet :-)

@@Cnctrldotcom My chuck has been fitted on by freezing the arbour to -24C and refitting, I failed to heat up the chuck due to turning on the wrong kitchen oven (My wife was amused). But subsequent misuse of the pillar drill resulted in the Morse taper falling out, the Jacobs B6 held tight this time. I think my pillar drill may need an overhaul to fix the vibrations using big drills, it sounds like train at the best of times. I was trying to drill 25mm in 3mm steel sheet parts at first, I have settled for 18mm drilled hole to be opened up later to 27mm by boring in a four jaw chuck on mini lathe. Thank you for the advice re. heat induced interference fit.

Hey mate, by any chance would you know where I can find chuck removal wedges for B tapers? My keyless chuck has a B16 taper, all I can find are Jacobs Taper wedges.. Or is there a different tool and/or method when it comes to removing B Taper arbors/chucks?

Sorry, no idea. Mr Pete did a video where he made some wedges the other week (kzread.info/dash/bejne/c6iCr5pmhrjcoso.html). They were for a Jacobs taper but I'd imagine the technique should work for you as well. Can you not access the back of the taper and tap it through with a bar?

McMaster if you're in the states.

You could stone the high-spots on that taper if you have an Indian stone, creating better contact. A round india stone can clean up the ID taper. There's no way to 'cockeye' install a taper. Isopropyl 99% is a better cleaner than acetone because acetone boils away far too quickly, less than a second, leaving the oil in place on the part.

Is that an Optimum drill press?

It's from Axminster in the UK but I believe the same design is re-badged and by many tool sellers.

Now you mention it I can hear it. One side of my family is from the south of England, around London way, and I seem to have picked up roughly that accent. Photonicinduction is from London I believe.
