Hi
I have for many years found hacksawing tiring and frustrating with some jobs coming up where I will have a lot of cutting up box section. I have decided to build a compact powered hacksaw that will fit on my bench top, equally I don’t intend to spend a lot of cash on it either so its being built out of whatever I have on hand.
The inspiration for the design comes from a You Tube video on a 3D printed power
So I have drafted out a model (images attached) which I am going to attempt with the material I have.
The whole saw 360mm long, 220mm wide and 180mm tall.
The vice has a capacity of 120mm should cope with sections 60mm thick.
The stroke has been sacrificed for compactness and is 60mm running at 60 strokes per minute.
The saw motor and cabinet is hinged at the rear and its own weight applies a load to the cut.
The basic design uses a 12Volt 2.2Amp motor.
The motor speed is reduced through a gear train which I intend to try 3D printed gears.
The saw is fabricated using rod which is held and guided by rollers on a fixed rail.
The colours in the model are not accidental:-
Blues are steel sheet or tube construction,
Orange are Aluminium stock,
Yellow are cast Aluminium
Gold 3D printed parts
Magenta bought or turned parts.
First up the gear train.
