This is my new work bench. My old one was not robust enough for the work I wanted to do on it and I came across a lot of 50mm thick beech plywood that was going in a skip. Its really heavy stuff, it has something like 30 layers in it, each the same quality as the outer layer. Its assembled using M12 bolts for strength and to make it easiy to dismantle.
Its my take on a Roubo bench with a leg vice and a wagon vice. I intend to add a bench hook later.
It needed to be high enough to work on without getting back ache, solid enough to plane hardwoods without moving and also portable, albiet dismantled.
I did try and make my own wood screws for the vices, however I got as far as making the female threads before I decided that my time would be better spent finishing the bench and getting some other projects out of the way rather than battling with wooden threads, they will come later. In the mean time I’m using threaded rod for the screws on the vices, which work really well.
The Leg Vice opens to about 12 inches, there is no parallel bar on this as it can move the full length of the bench. I’m using chocks to keep the leg parallel. The thread is M12 threaded bar. The holding power in it is massive. Nothing moves in it at all. Its also easily removeable.
The wagon vice has two dog holes and runs on an M10 threaded bar and wooden runners. I made the dog from oak, however I need to modify the design to get them to hold properly as there is no reverse edge in them to hold the work yet. Perfectly parallel dogs don’t hold that well!
The parallel leg is removeable and can also be positioned at any point along the bench the same as the leg vice. The dog holes in it match the ones the ones in the leg vice.
All that remains to do is put some dog holes in the face and maybe some sort of protective finish, although I don’t know what yet!
Total costs? a whopping £20! (in nuts bolts and threaded bar)
