I built this 22 years ago with just hand power tools but it has held up beyond my expectations. Hesitated to upload here, but I like to show it off and some may get inspiration from it.

Over the years I have put countless feet of wood through this saw, even cutting small firewood and the only thing I have ever had to do to it is change the occasional dull blade. I now have a large 20” General but still prefer this one for small work.

Old as it is, I don’t have build documentation. The design is loosely based on a plan I saw in an old Popular Mechanics magazine and is a relatively simple construction. For the main frame I cut a template out of cardboard and used it to trace out and cut 5 laminations of 3/4” plywood, some with additions depending on where it was situated in the frame. The laminations were then glued and screwed to each other producing a very solid frame that will withstand much higher pressures than this saw will ever be subjected to.

The motor is a 1/2 hp sealed Leeson motor. It is housed in the sheet metal base, the two wood grills allow cooling air movement.

The adjustment handles are all discarded valve handles, except for the blade tension handle and screw which is from a scrapped X Y vise.

I didn’t have a shop when this saw was built so the tension and tracking weldment and blade guide weldments were welded up in the shop at work.

The table tilts 45* on solid laminated plywood trunnions, clamped between the middle frame lamination and two steel plates bolted to the frame.

The upper and lower ball bearing blade guides. All are adjustable in oval mounting slots.

Lower blade guide.

Upper blade guide and guard.

I have it on casters to move around the shop and it has a efficient dust collection port.

I am very envious of your tool building prowess.

Very nicely built saw, Looks much stronger and better built than most of the ones that are being built today. Most likely is quite quiet too being wood construction. I have an old metal one that I restored and it is quite noisy.

Thank you bushmaster. Yes it’s certainly quieter than my big General, the bearing guides make some noise, composite or wood guides are quieter but can generate alot of heat if not adjusted correctly. The trend seems to be towards many dimension size pieces to build the glued up frames. I still think full frame plywood pieces properly laminated is stronger and will produce less movement than dimension wood. The weak spot in gluing up many pieces is going to be the one bad joint you overlooked. Just my opinion, there are many very nice saws being built out there.

I took too pride when I have collected the tape saw and listened to her singing…... LOL….. it isn’t clear to me how you regulate a gap between bearings and a saw (cloth)??

- Sasha

A couple of strips of standard weight writing paper is easy and generally acceptable clearance. The problem arises when changing the hight of the guide arm. Not so much of a problem on a closely fitted manufactured saw but on a home built the clearance can change with height requiring resetting of the guides. Less of a problem with bearings than solid guides.
