I'm also looking for a scroll saw...
So I'll put my hand up too.
However,
I can't figure out from the photos how this one works. The bow appears to be a solid casting and part of the base. How is the top of the blade held tight and move with the eccenter at the bottom (or whatever makes the blade move)?Cheers, Joe

I had a quick look at the pics Joe, and my take on it is similar . I think the overarm is solid and stationary, and the cylinder on top includes a vertical slide, a piston or bellows to provide air for the puffer, and a substantial spring to keep the blade tensioned. The crankshaft at the bottom operates a pushrod to a vertical slide mechanism and lower blade mount, ensuring that the blade motion is purely vertical.
I'm just not sure that it would qualify as a scroll saw while fitted with section of hacksaw blade as shown, as I suspect that the minimum cut radius would be quite large.I used to be an engineer, I'm not an engineer any more, but on the really good days I can remember when I was.

Hi,
The "scroll" saw is still available.
However, it's (and me) are in the Hills District now. Pick up is welcome. Can be posted I guess.
TWIS, I thought it was a scroll saw but I could be wrong (often).

Joe,
FWIW many years ago (1949?) my father wanted a power saw, and settled on a heavy duty scroll saw type of saw as the cheapest alternative. He bought a kit consisting of a similar upper fitting to the one in the scroll saw photo as described above by malb, and an unmachined bronze eccentric strap casting. The kit was designed to be used with 1 1/2" pipe and fittings for a frame, and the upper fitting was clamped into a 1 1/2" pipe tee with a 3/8 brass bolt. The square spring-tensioned plunger in the upper fitting was split to accept the blade and had a 3/16W screw which went through the blade, and when tightened clamped the blade firmly between the two sides of the split. Machining the eccentric strap and making the eccentric was an early project for the near new Brackenbury and Austin lathe.
From memory the upper fitting was about 175 mm long, and its position in the pipe tee could be varied to adjust the spring tension or to accommodate blades of various lengths. I remember we used to use bits of band saw blade or hacksaw blade with the ends annealed and drilled for the 3/16 clamp screw. For fine work we did use fret saw blades with the pins removed, but can't remember how we clamped them in place.
For years this was our only power saw, and cut a lot of timber, and occasionally brass plate and sections. Mounted on the brick workshop wall it ran completely trouble free for many years powered by an old 1/4 HP ex-washing motor.
Frank.

So this could well be the "up-market" version of the DIY version your dad built.
I'm pleased to learn that it could be used for any kind of blade - and re-register my interest in this machine...Cheers, Joe
