A candlrstick i made years ago

I've turned the above so far on a faceplate. I was planing to then mount it on an expanding jaw on my Vicmarc 100 chuck using the hollowed rings on the underside. The largest hole is 93mm diameter / 7mm deep but not dovetailed. The second inner ring is 74mm diam / 18mm deep. There is a 22mm hole drilled right through. I only have a 47mm jaw! It is gnarly oak so I need some grip. I could buy a 72mm jaw (at a cost) but the hole is still not dovetailed (It is essentially reverse dovetaield to grip a lid which currenlty fits very nicely!). I'm looking for better and cheaper suggestions.
I could lighlty grip it on my 47mm jaw and turn a tenon and then part that off when finished (it will shorten the end result)?
Any ideas welcome
The club has been approached with the offer of various polishing materials (there also stains and waxes not included in the photo). Asking £18 but may negotiate.
They are locarted in Clun. If interested contact Eleanor Smith ele@elandjsmith.plus.com
I'm looking to purchase a bandsaw for about £300 and I have narrowed it down to 3 possible contenders.
Record BS250 10"
Rutland
Charnwood BS250 10" inc stand
I would appreciate any feedback , positive or negative, on which one to choose from all your years of experience between you.
Many thanks.
Ian,
I got a second-hand Charnwood 350 a few months ago - seems exaclty the same as the 250, just a bit bigger. All good so far: solid build and easy to set up, adjust etc. The Rise & Fall guard was stuck when I got it. Easy to remove and clean out. There is some back&forth movement on the blade, which I think is due to the 2 wheels not being exactly aligned. Charnwood tech support is fantastic. Following a quick call to discuss the issue they sent some instructions on how to adjust and fix it(which I will do when I get time). Interestingly the brand for the instructions is Rikon. I think it is exaclty the same bandsaw and maybe another brand worth looking at? Probably all made in China by the same manufacturer.
Hi Paul, I think I probably meant a jam Mount, not friction. Made an oak “male” ” to tightly fit into the hole. Not a flat plate for friction. Was turning it this morning. All held tight and done 👍🏻
