Thread: Nova Cole Jaw Set - rubber stoppers

Only problem is that it did not come with the 8 rubber stoppers nor associated screws.

After a quick online check yesterday they do not appear to be sold separately so I assume that replacements could be made. Any ideas on whether I can actually make these?

Jane I guess you mean this set try contacting Trend Timbers


Failing that McJings have buttons also.

Your local engineering supplies should be able to help with the machine screws.

I have used, successfully!, door stoppers. Get your machine screws to suit the depth of the door stopper. There are different stoppers, some harder than others. I use some white ones which are quite soft and use them for holding the bowl when finishing so they don't mark the surface.

Thanks for the replies. I now also realise they are called "buffers". It helps when you know the search words to use! You then get some hits

It does help knowing the terminology. With my set of Cole jaws I use the ones that came with then and I picked up a few more thinner ones that allows me a little more flexibility.

The machine screws are a standard metric thread, can't remember the size off hand. I bought longer screws so that I can lift the buffers up a bit (using nuts to lock them at the right height) to allow me to hold convex shaped bowls too.

I bought a set of Cole Jaws second hand. No screws or buffers were with them. The threaded holes are 6mm bolts size and for buffers I used some 6mm neoprene fuel line. We have a bearing and bolt shop and both items were easily found.

Cut some wooden dowel and drill a hole through it fix with the correct sized screw for added protection some plastic pipe pushed over the dowel. Or is you can find them a Robert Sorby supplier who can get some as the make cole jaws

LovesToRide and I just ordered a set of Carbatec: https://www.carbatec.com.au/woodturn...jaw-buffer-kit

I was grabbing some 6" DC pipe anyway, so it was easy to tack on. Grabbed a set for myself too Ill now be able to turn to foot off my bowls a bit better. The standard rubbers are OK, but not as good as this kit

Thanks for the help chaps.

I've used white rubber "corks" with holes; bought at home brewing supply shops. Several sizes available.

Cheers,
Joe

Most bolt suppliers can supply the hex socket head machine screws for the buffers, however Nova / Teknatool machine cap screws used on the jaws are not standard and are quite difficult to find as non OEM.

While these are Vicmarc Cole Jaws, the principle is the same. Literally changed my rubbers last week after a rummage around in Clarke Rubber. About $18.00 for the 8 of them.

I'm not in Aus so I don't know what's available there, but I just bought a packet of machine screws and nuts from the local hardware. They fit in the rubbers exactly the same way that the original ones do, but are a bit longer. If I'm not mistaken they're called pan-head machine screws. Mine have a slot for a flat screwdriver, but you do get them with Philips or Pozidriv heads too.

The heads on the screws used in the standard jawsets have a larger diameter than normally stocked. So far I have not been able to locate a non OEM supplier for them. Screws for the rubber stops only need to match the stop.

Sorry, my bad, I didn't read your post properly and assumed that you were talking about the screws the hold the rubber buffers on. I see now though that you were actually talking about the screws that hold the jaws themselves onto the chuck.
