Low profile clamps

Ned Ludd:
Call me psychic (as opposed to psychotic)  :D

I bought my set of casting from Kirk about two years ago at the Midlands show, but have yet to finish them, only got the base parts done so far up to the part you had clamped to the table.
Some questions for you;
How are you getting on making the jig, what difficulties have you come across?
Did Kirk ask you to do a write up too?
Why did you choose the "Potts" version over the "Duplex" one?

kwackers:
I haven't machined anything on it yet in fact it was whilst staring at the castings and trying to figure out how I was going to machine that I decided to make the clamps.

I think I probably bought it at the same time/show as you! I've a number of other Hemingway kits - both finished and unfinished. The Potts jig was bought to use with my cutter grinder (another from Kirks), I'm not sure what the difference between the Potts and Duplex versions are (other than there are apparently some mods mentioned in the notes).

I'll be up at the exhibition again in a couple of weeks although I'm under strict orders from my brain not to buy anything that requires any machining at all! I don't get much time in my workshop and at this rate I'll have nothing but tools to show, be nice if I get round to some non-tool projects  (once I've finished all the tool projects currently staring accusingly at me from under the workbench...)
Ned Ludd:
Why bother even thinking about making anything other than tools, there are never too many to have. Toy steam engines are all very well, but tools actually do something useful. (Very much said with tongue firmly embedded in cheek.)

The Duplex jig is made from standard stock materials (barstock) and therefore much cheaper to make, plus there are step by step instructions (ME late 1951).

I believe I'm going to have to make another "to do list", these are great and look to be a solution every machinist runs into on a regular basis.  Thanks so much for the clear and lucid design and demonstration on making them.  Kudos for the ingenuity :bow: :bow: :jaw: mad jack
