You're going to have to stop showing pictures of that chest, as I keep eyeing up a piece of boxwood and a new Skelton handsaw to cut the veneer.There would have been no point in the outside of the chest being decorative.
How was it used?It's a sash scribing gouge for scribing the moulded parts of window sashes.
Interesting link. Have a feeling that very specialised tools were not that commonly used, firstly because there's not many of them about but mainly because the work can be done without them, and probably was, by and large. Semi specialised tools - varieties of moulding plane are very common and rebate planes probably most common of all old woodies still kicking around.Very old school and went out of use quite a while ago.
You're probably right.
There's loads of theories thought up by quasi academic types, who have never held a hand tool, let alone used one on any live project.
Take the sash scribing plane in that article. It's a git to use unless you rack up a good quantity of bars in a clamp and do them all at once before they are moulded. If you don't do that the moulding gets trashed, no matter how sharp it is.
How was the scribing gouge I have used ? I don't know.
What's the purpose of the wooden sheath ? It might be a depth stop that gets shortened as the gouge wears, but I don't know that either.
The best way to find out is by getting hold of the tools and putting them to use.
Yes butLet's turn the light on.
A few years my pal Richard Arnold made a short video of a sash scribing gouge in action. Take a look on his Instagram page.Yes but
The most complicated work in making the sash
box is cutting out the sash pocket in the pulley
stiles, through which the weights are reached. It is
necessary to make both transverse and
longitudinal cuts in a position that cannot be
reached with general tools. A special chisel – the
sash pocket chisel – was developed for this job,
though the exact way it was intended to be used is
still a matter of speculation.
She's wrong about the most common method being complicated - it's easy I've done hundreds - and she says the use of the sash "pocket" chisel is a matter of speculation - in other words she doesn't know. Best explanation was JobandKnock's I thought Best vintage Chisels
Looking at the mystery scribing chisels above, I winder if they were designed to slide in one of the various other accessories, "sticking boards" or some sort of guide of its own? It'd account for the very precise and consistent shape of the handle - it looks designed to fit something.
Right! Seems to be the answer. Had to watch it a couple of times to see what he was doing. The woodwork behind the blade stops it going through and breaking out so you have to cut it from both sides for a clean cut.
A very good option when something is too hard to pare accurately. Great for plane beds and adjusting anything end grain, even back into the grain (sometimes difficult to pare).All this and we haven't even started to talk about the blunt chisel and the technique of using it.
