To Squish or not to Squish?


You might be forgive for wondering what this:

















...little block of oak is for?  It has a square hole going through the length and a 6mm groove on the underside.  The answer is that the hole fits my Chalco stamp...















...so that when it's fitted into said orifice it:















...pokes out thus.  If you've ever tried to use on of these stamps, they're notoriously difficult to use properly by 'tapping' with a maul...it's either too hard, or too soft and very difficult to find the right 'Goldilocks' sweet-spot (which also depends on the hardness of different timbers) and of course, once struck it can't be re-tapped 'cos it won't line up!

So what happens to the slot?...said slot then fits over a:

















...sash cramp bar, so that when the test piece (rosewood here) is  squarely supported:

















...I found a half-turn on the tommy-bar was enough to make a very satisfactory:

















...makers mark.  Something softer like a piece of mahogany took a quarter turn...and turning a cantankerous, awkward little job like this into something with a little control is quite satisfying.

I thank you....

  1. Sorry I forgot to get back to you Rob with a pic of my Jig, glad you liked my idea, its a much simpler version and therefore better than mine! Simple is always better. I have found that the stop can tilt and give an uneven stamp sometimes - there are 2 ways round this I have found, counter angled pieces that slip over said stop / physically clamping down the piece being stamped. Hae you found this to be an issue yet? All the best, Berin.

  2. Does that mean it is now a squish rather than a stamp?
