billyO Posted June 27, 2015 Share Posted June 27, 2015 Hello all, hope the summer isn't causing any body parts to melt.....Too hot to fire up the forge, so thought I'd do a bit of grinding/filing/sanding. This is a replacement blade for an Opinel with a broken tip I've had for years. And, being impatient (although I justfy this step as an aid in looking for flaws...)Starting billet: 11 old sawzall blades (with teeth ground off). Folded 3 times (88 layers), twisted, flattened and grooves cut diagonally across the billet opposite to the twist. Quenched in hot oil, tempered at 450 for 1 1/2 hours.Hope I remember to finish this... as alwayspeace and lovebillyO Quote Link to comment Share on other sites More sharing options...
jmccustomknives Posted June 28, 2015 Share Posted June 28, 2015 Dang cuz, your up in the great NW. You want hot, come visit my shop. 98F, with a gas forge going and swinging a 10lb sledge. How long would you last? lol. Turned out pretty good on the pattern. I'm really surprised it welded up, it's been my experience that many band saw type blade will not weld together.

Michael Cochran Posted June 28, 2015 Share Posted June 28, 2015 I've welded up a couple billets from old sawzall blades. It just takes a little prep work like anythin else. In fact that was the first stuff i welded up in the fire and I find it easier than mild steel. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 29, 2015 Share Posted June 29, 2015 BSB likes to have some plain steel in between them---like pallet strapping---then they weld up a treat! Quote Link to comment Share on other sites More sharing options...
billyO Posted June 30, 2015 Author Share Posted June 30, 2015 How long would you last? lol. not very....or I move VERY slowly.... And as I think back, this billet may have been a combination of sawzall blades and various circular saw blades cut up to match. Quote Link to comment Share on other sites More sharing options...
Dodge Posted June 30, 2015 Share Posted June 30, 2015 I second what Mr Powers said about bsb. Also, alternating with pallet strapping, it will yield more contrast with the acid etch. I've thought about trying other blends, but (for me) bsb and banding is so, abundant, I would rather hone my patterning technique with something I have had good welding results with. Then when I am comfortable with what the layers will do under a give manipulation, I will try more exotic metals. YMMVScott Quote Link to comment Share on other sites More sharing options...
norrin_radd Posted June 30, 2015 Share Posted June 30, 2015 (edited) Great pattern on that blade.Does the same thing apply to band sawmill blades? Edited June 30, 2015 by norrin_radd Quote Link to comment Share on other sites More sharing options...
