Grotty Found Object To Useful Gadget.

While walking down our High Street, my eye was caught by a discarded lighter in the crack of the pavement. Remembering something from ‘Cheap Thrills In The Workshop’, by Charles Lewton-Brain, I brought it home to cut out the flint wheel, discarding the die-cast thumb wheels on either side.

Drilling out the softer steel axle was easy enough, done in two stages with some lubricant, to accommodate the screw of a screw mandrel.

The result mounted, is a rotary file for flex-shaft, which can be used for trimming round and oval holes to a scribed line and other jobs, where a file won’t go, or simply because you prefer rotary tools. Dennis.

You're too clever Dennis. Way too clever; I can't work it out at all.

Clever idea Dennis but why bother when you can buy sets of diamond burs like these from Cookson;
http://www.cooksongold.com/Jewellery...rcode-999-6389 all for £12.
Or there are cheaper versions from Amazon;

Sorry Cookson but £5 for 30 different shaped diamond burs can't be bad.

I tend to be relatively careful (c.f. "overcautious" maybe!) with my diamond tooling - the carbide burrs (including a couple of lighter wheels), while brittle, get used more for hogging out material and are usually less susceptible to clogging with softer metals.

??? Dennis.


James, You're right, I like new things too, but in this instance it's satisfaction from getting something for free, re-cycling waste, and lastly because the cheap sets have 3.0mm shanks, which won't fit my micromotor handpiece.

These wheels also give a superior bright cut- try it for fun, Dennis.

Dennis I often thought the C Lewton-Brain was for quacks until I made a diamond fly wheel, but those were the days when time was in abundant. Why don't you make a collet for the handpiece or better still get a 'jacobs' handpiece for around £15.00, although big and chunky they're great for holding the>3.00mm shanks. If you could free some mind power do you have any solutions for a cheap wax injector, I have two on the go with different casting waxes in but need a third for injecting green carving wax for small quantity waxing, any ideas??

You've seen this article I presume?

Ever since I read this thread I have had the tune for Steptoe and Son in my head :0)

Lopez, you probably know that with all but the most expensive micromotors, the handpiece is fixed and cannot be exchanged. The best I can do is to use a mandrel with interchangeable collets, but for most purposes that makes the tools too long to be useful and liable to bend suddenly.

Fischer advise in their catalogue, that you first experiment with their practice flywheel, before using the diamond one. I certainly don't have the confidence to set my own as a tool.

You have given us a lot of interesting and valuable posts in quite a short time, but I am wondering whether you could fill us in a little about yourself. I could only find two women Lopez jewellers online and I doubt either is you? Dennis.

You have to clack your tongue for the hooves as well.
