Introduction: 3D Printed Power Hacksaw

This is a power hacksaw that will cut mostly anything. From wood to plastic to steel. I have also tested this with stainless steel. The videos below show it in action as well as show the component arrangement.

Step 1: Bill of Materials (BOM)

Bill of materials

BOM 6x – 608 Roller skate bearings 2x -100mm 8mm all thread rod. 5x - M8 bolts. 1x - 40mm M8 bolt 2x – 6mm ID. 15mm OD bearing (had these laying around) find what you can, modify the files as necessary. 1x - 60mm shaft (matches the bearings) 12x - wood screws 1x plank of wood. Approx. 300mm x 450m 3x Spacer wood 2x4 is what I used. ~ 50mmx100mm 1x – Geared Globe Motors Model number 409A502 1x – 19v PSU 1x – 5A switch 1x – Ikea $7 table leg, or 50mmx50mmx400mm chunk of wood. BOM Standard size. For standard size, I still use metric bearings. 6x – 608 Roller skate bearings 2x - 5/16 all thread rod. 5x - 5/16 bolts. 1x – 2inch 5/16 bolt 2x – 6mm ID. 15mm OD bearing (had these laying around) find what you can, modify the files as necessary. 1x - 60mm shaft 6mm diameter (matches the bearings) 12x - wood screws 1x plank of wood. Approx. 12inch x 16inch 3x Spacer wood 2x4 is what I used. 1x – Geared Globe Motors Model number 409A502 1x – 19v PSU 1x – 5A switch 1x – Ikea $7 table leg, or 2x2x16 chunk of wood.

3D Printing Instructions.

Settings.

.3mm layer height. ABS highly recommended.

The Rod and crank should be printed at 100% infill for strength.

The Remaining parts need 30% infill.

Step 3: Assembly Instructions.

When assembling the hack saw the bearings should be pressed into the plastic. This is the reason I recomended ABS as it does have some flex.

You should also debur all plastic parts before assembly. The rest of the parts can be seen. Use common sense.

If you can, reverse the rotation, most saws of this type have a stroke count between 60- 80 S.P.M., and the cam or Pittman arm turns anti- clockwise. This may improve overall performance, but all in all an excellent build, fav'd and voted up.

Thank you.

I have been enjoying reading through instructables nearly daily for more than a year. time to give back eh?
