You can never have enough work bench space.
I have been meaning to do this one for ages now, finally got around to doing this a few days ago ( just the right piece of scrap plywood happened to be in the shed at the time) the project took about 20 mins to do and is proving to be very useful indeed as it is at a perfect height to work at while standing thus making things easier for my bad back.
I am still able to use approx 1/2 of the lathe bed with the bench attached, this is usually more than enough to carryout most of my turning projects.
The bench is made from a piece of 3/4" plywood and is easily removed when the full lathe bed is needed.
3/4" plywood scraps approx 24" x 18"
3/4" plywood scraps
M6 coach bolts long enough to suit the lathe bed.
M6 wing nuts
I used power tools and a nail gun, but hand tools could also be used and it could be put together with wood screws.
Thanks for looking and i hope the idea inspires your own mods.
