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....
