What Michael says - 18 DP, so not Drummond. If your Myford is pre-metric and has loose change gears they will be 20 DP. Might be interesting to check some of them to see how close they are to the theoretically correct diameter to produce exactly 20 DP.

Hi Guys,
I thought that I would post some pictures of the bits that had been in the citric acid bath.

First up the M&W callipers. I'm very happy with the way these came out ! They had two days, maybe 60 hours in a cold citric acid bath. I say cold because the workshop was only about 50F the whole time.

This 3 inch Bahco adjustable spanner cleaned up well too ! It was sized solid, so its been stripped and cleaned then lubricated. Just a pity about the pitting.

The scale came up quite well, its a good quality one as well. The callipers are a German brand, unfortunately the jaws have taken on some wear near the tips, but quite accurate between the body of the blades. The inside jaws don't seem to have had any use at all.

Last but not least is this item. Its been very well used. Non of the edges are sharp. All the teeth are worn as are the first 20 mm of the flutes. There are no visible markings on it to indicate what it is. Its 1/2" in diameter and 3" inches long. There is a hole in each end, but its not a centre as such since its flat bottomed.
Does anybody recognise this tool ?
Thanks Guys.Best Regards:

Mystery Tool bit.
Hi Guys,
I'm surprised that no one has commented about this item.

Hi Guys,
I've just discovered a bit more about this tool !
I decided to try and clean out the muck that was in the hole in the top and saw a hexagonal hole below. I couldn't figure out why there should be a hex hole there, so I stuffed an Allen key into it and discovered that there was a 10-24 UNC grub screw in there. I measured the threads on the grub screw, which was how I discovered that it was a 10-24 thread in the hole. It extends to about an inch deep.Best Regards:

Hi Ray,
Thanks for your post ! I think 1/2" diameter is probably a bit small for a blasting hole.
All the explosives that I've had my hands on have been sticks of gelignite about 1.5" inches in diameter and 8" inches long wrapped in waxed paper. You don't want to get the stuff on your skin either !
I'm guessing that the threaded hole is so that an extension rod can be screwed in to get extra length. I did wonder if it could be a counter bore of some kind.Best Regards:
Baron J.
