I made a saw machine
I designed and made six proto types before this one.
The semi final design uses a full sided jewellers saw frame and it has a stroke of 70 mm so it uses all of the blades teeth.
It is powered by a shaded pole fan motor, so it’s more quite than a flex shaft, except when you cutting.
About 250 strokes per minute.
Its got a magnifying glass for old fogies like myself. When you use the magnifying glass one can cut very precisely.
Also 2 saw blade holders.
A ten watt aliminium led spotlight on a goose neck.
390 mm (about 15 inches) high and 250 mm (10 inches) wide and 200 mm ( 8 inches) deep.
The best thickness of material to cut is from 0.5 mm to 3 mm mm.
Steel, gold, brass, whatever.
The hold down foot makes it that all you got to do is steer the material.
It is really easy to use and I have to replace the blades only when they get blunt, not when they break.
They do break though, and I suppose they could stick you, but hey, you buy a circular saw and that’s more dangerous.
Anyway blades from 1/0 to 8/0 work just fine.
I’ve broken plenty though, so when I ran out I bought a whole lot of different brands in small quantities so I could test them.(not mentioning brands)
The two switches on top are for stop/start and light on/off
The clear perspex circle is so it can be turned by hand, like a sewing machine.
The catch tray is removable.
Check the sexy saw holders on the side.
The Pesrpex round handle is much needed to advance it slowly, like when a blade needs changing.
Early design. I played around with MANY foot designs.
No 17 foot design is my favorite so far. The foot plate is easily removable so making a different design is no big deal.
