Cup washer press

[Maker]

I mentioned before about needing to make a couple of cup washers for a Blake water pump. Well we ordered some 4mm leather so I got cracking:

The body is 2" x 4" x 4" steel, bored out to 1 15/32", 7/16" deep. The brass plug is 1 5/32", approximately 8 mm less than the hole, to compensate for the thickness of the leather. There is a 10mm threaded hole in the bottom for the bolt to screw into.

To use it, you cut out an over sized leather circle with a hole in the middle, soften it in water and tighten it between the plug and the hole. With it in the press, trim the excess leather and leave it a few days to harden. Then take it out and hopefully it will be a nice tight fit in the cylinder of the pump.
That's the theory anyway, I'm yet to test it, fingers crossed.

There's no reason to make it from thick steel, MDF would work just as well.

I'll take some disassembled pictures tomorrow.

Not the only one that uses both imperial and metric on the same job then. Can I have a 12mm bolt 2" long please?!

I made a similar thing to press shallow cups into a piece of sheet steel. MDF for the female bit worked well as you say. Yours looks like much more fun to make though !

Chipmaster working well I see☺

MDF doesn't like to get wet though, it expands and goes soft, horrible stuff really.

Yes, working very well. Best £600 I've ever spent.

Use a bit of plastic chopping board instead(other sources of dirt cheap polymer sheet are available).

Maker , I can't view your picture as I don't do Faceache etc. Any chance of putting the picture in to the thread please ?

Sorry about that, I've been sending them to myself from my phone then copying and pasting them here.
Is this showing?

If so then could a mod please put it in my first post?
Here's the washer it made:

I don't think it's deep enough but I'm not sure.

what came off?, the ones I remember were quite a deep cup

Done

It's from a Blake but the originals were long gone. I made the hole the same depth as the things that fit inside the washer but I didn't add 4mm for the thickness of the leather.

try it... whats the worst that can happen?

I've got to make another bolt, brass washer and a couple of great big end cap type things and then it can be tested. It's a big lump so once it's working I think he's going to sell it
