car boot tragedy

[Paul BarterParticipant @paulbarter66156]

Hello all, I thought I had a stroke of luck at a car boot near me, found a nice clean, unrusted Dormer adjustable reamer. However when I got it home I found a chip on one of the blades. My question is, are spare blades available?or is a chip on only one of the bladesof no consequence?Thanks to anyone who responds.

Try it and see

Roy is right, you could try it on a scrapper and see what happens, if your lucky the chip will not matter if it only means it doesnt make full contact on part of the material. If the chip is on the start of the taper it might make it harder to cut to begin with.

Hello Roy

Thanks for responding, I am a bit concerned that the chip will produce a ridge which may not be removed by the other blades.I will try it on a trial bore.As a new,albeit not Dormer, djustable reamer seems to be available for £15 or so I wondered if replacement blades were available, along the lines of those fitted to portable electric planers

I would have thought it a good idea to round off the sharp corners of the chip first to prevent possible scoring.

I can't see that a chip on one blade will be a problem, I doubt if spare blades are available but I stand to be corrected.

If its along one edge rather than near the end, you should be OK. Might be worth stoning teh chipped area in case it has a raised burr.

…Back when I was a very poor young man I made a couple of blades for some old adjustable reeamers….still got them somewhere… I used some 'ground steel stock' , what they now call 'gauge plate' in the right thickness and after careful hardening in the forge on a shovel and tempering in the ash they worked fine……..If I recall, I made the head stock for a amall lathe with them.

I don't think I would worry too much, I have some reamers that only have cutting flutes on about 240degrees of the circumference – they cut OK.
