    Thumbs up More Christmas Goodies !

    Hi Guys,

    I've spent a little time cleaning, de-rusting and examining some of the tools and bits that I was given...

    30-12-2019-001.jpg
    This is the box of goodies that I was given. As you can see quite a varied collection of bit and pieces.

    30-12-2019-002.jpg 30-12-2019-010.JPG
    These are some of the items that are about to receive the citric acid treatment ! The picture on the right is a "Moore & Wright" divider. Its sized up solid. I hope that I can resurrect it.

    30-12-2019-003.jpg
    There is quite a selection of slitting saws, some are only 20 thou thick, the ones at the bottom of that pile are 3/16" inch thick. I also found two 3/16" inch thick broaches, neither have been used.

    30-12-2019-006.JPG 30-12-2019-004.jpg Carbide Drills.jpg
    There is a full packet of Dormer 1/4" inch 0101 series drills, several carbide countersinks and a couple of carbide drills. These surprised me somewhat, I've never seen a drill calibrated to two decimal places before, one is 3.63 mm and the other is 5.68 mm. Obviously specially made precision drills. Both are split point six facet ones made in Birmingham UK, as are the other carbide tools.

    30-12-2019-008.JPG
    Now this Item has me stumped ! Its HSS and appears to be a drill of some kind. The point produces a 1" diameter countersink, but the four stepped edges have me baffled. If you used this to drill a hole up to the last step, the hole would be 2" inches in diameter and have a flat ring around the edge. There is no makers name or other identifying marks other than those you can see in this picture. Its also 1/2" thick and 2.375 wide.

    30-12-2019-009.jpg 30-12-2019-007.JPG
    There is a set of carbide lathe tools and these three lathe Change Wheels and a pair of chuck jaws for a 100 mm Bernard chuck, based on a comparison with the jaws on my Myford. The Change Wheels however are far too big to fit my lathe, even though the bore is the correct size. The teeth are probably 14.5 PA and won't mesh with any of my gears. Knowing that the origin of these bits had Drummond lathes in the factory, these gears could be for those lathes.

    A nice present with some useful bits and pieces.

    The serrated one that had you stumped looks like some sort of threading bit.

    Where did you get this awesome stash of goodies?

    It is a HSS Spade Drill, similar to a Madison.

    Hello from Ol Steamer.
    I think the spade drill is E.S.C. brand.

    If you can, remove the spring from the dividers before treatment.
    Spring steel sometimes doesn't survive rust treatment. I wonder if micro cracks could be the problem, but I've heard several stories of spring disintegration.

    Correct.
    The English Steel Corporation of Sheffield manufactured High Speed Steel tools from the 1930's until( I think)
    the 1990's. Noted for their Butt-Welded HSS Turning and Planing Tools.

    Looking at the gears they would probably be either 14 diametral pitch (DP) or 16 DP. Drummond lathes and their clones used relatively uncommon 14 diametral pitch gears with a 5/8" bore, while many other small lathes used the more common 16 DP gears. If you want to check the DP of the ones you have to establish whether or not they are likely to be Drummond gears the formula is: DP = N+2 divided by the OD where N is the number of gear teeth and OD is the outside diameter of the gear in inches.

    Thanks for that bit of info, I hadn't realised that was a brand mark ! I did try to find a patent based on the number without any luck. I is a bit of a beast though.

    Happy New Year all.

    A bit late now its been in citric acid for a couple of days ! I'm going to take it out later today and give it a scrub. If I recall correctly the "M&W" tools had some kind of coating put on them to stop them staining from sweaty fingers.

    Happy New Year All.

    Thank you ! I knew nothing of this company. At least I now have some concrete info to use to search on. Its sad that most if not all UK engineering manufacturing has gone and we are becoming dependant on other countries for machines and tooling.

    Happy New Year All.

    I used citric acid in combination with a small electroplating unit to remove rust from a pile of old spanners. After cleaning them up I sprayed them with Wurth Silicon spray. Years on they still show no sign of rust.

    Happy New Year to ALL also. Nice haul on the goodies too,
    Eventually it'll be like the automobile, there'll be one car maker that has the monopoly on it at, pay my price or walk!!!!!
    If we look at China, it was basically a third world country, have a look at the progress that they're now making, freeways through mountain ranges, over seas to man made islands as stepping stones.

    Hi Frank,

    Thankyou for your post.

    Here is a picture of two of the three gears, there are two 32 tooth ones. I've only photographed two of them. I've written the size, measured across the gear outside the teeth. I measured them in mm. They are 5/8" inch bore and 3/8" inches thick.

    01-01-2020-007.jpg
    Using your formula the 32 tooth plus 2 = 34/((47.96/25.4)=1.9") ie 34/1.9" inches gives 17.9 DP for one.

    For the other, 40 + 2 = 42/((60/25.4)=2.36") ie 42/2.36" inches, gives 17.8 DP.

    Sorry but non of these DP numbers make any sense to me unless I round them up or down. ie 16.5 or 18.

    Thanks:

    The numbers never come out exactly (round off error, manufacturing tolerance, measuring error). I'd call those 18DP myself.
