Here is my latest project, its a Scroll Saw and its powered by my Lathe.
The design is inspired (ok copied!) from this one by Corydoras, after a lot of hunting around, but I never found another powered by a lathe.
I wanted to take the drive for this from my lathe for several reasons, but mainly because its quiet!
Its mostly made from offcuts, the base is 60mm Beech Ply from my workbench build, the frame and arms are Ash and I used about an 1/8th of a sheet of 10mm Beech ply for the table and its support. The alignment bearings are mounted with Iroko and the lathe adaptor is an oak offcut. It has bearings in the rocker arms, drive link and lathe attachment, 14 in total (sounds excessive, but most are doubled up). The blade hangers are some old brackets I had which were modified with a hacksaw and a hammer to fit.
Blade changes are simple and require a few turns of a wing nut to complete. it will take standard length junior hacksaw blades or the larger scroll saw blades (fitted in the pictures). It runs on the lowest speed on my lathe and cuts brilliantly and is as quiet as I intended, probably because of the excessive amount of bearings! The lathe mount is the same as the one on the wall in the photos, which is my lathe mounted sander.
Total cost on this one was about £20, half on bearings and half on the 10mm beech ply. I haven’t done any sketchup drawings of it, but if anyone wants some I can do.
Here it is in motion:
