I have only had an interest in collecting braces and brace tools for about 10 years, and have had to stay focused to not deviate off the chosen path. I have deliberately stayed away from the Marples Ultimatum for the same reason as Andy "too spendy" but they have come down in price massively in the last few years. The only wooden brace I have is this Robert Sorby & Sons which I bought in NZ about nine years ago.
It was the first beech brace I'd seen, and was pretty impressed as was my older brother who encouraged me to purchase it. It cost me about NZ$600 which I now realise was faaar too much but a lesson learnt and no use crying over spilt milk.
I try to research patents and am always interested in others observations, for instance, I had no idea that Q.Backus may have produced the Tom & Jerry cartoons which of course opens up another facet of this otherwise Boring fellow, thanks AK for the heads-up.
Some of you will know of my fixation with Sheffield brace and plane maker James A. Chapman whose braces are FF here in Aus' though information about him seems to be thin on the ground. He made a brace, No32, which incorporates the ratchet patented by Albert Goodell (of Goodell - Pratt) in the USA in 1892. (No 488691)
Here the two together GP upper and JC lower
Tentatively I have dated No 32 at about 1911.
My obsession with Mr Chapman is that it appears that he embraced the American steel brace when other British makers were continuing to make wooden and scotch braces with their button and lever latches and yet up until the mid 1800's the Americans had been forced to buy their bits from England and Germany because their steel technology was not up to the required standard.
I'll leave it there because you've all nodded off.
Cheers,
Geoff.
