Hot cut hand shear hardy?

Recommended Posts

Thank you tp.   I’m glad to see it’s a usable scrap and I didn’t haul it home in my work car for nothing.  Hoping to get started tomorrow on the build after I put a block heater in the tractor

Well I got it put together.   Had trouble with the 1/8 leaf springs but 3/8 round bar was no trouble at all.  Leaf spring just cools to fast.   Made it so it can cut pulling down or lifting up. 

Bent the handle a bit trying 1/2” rebar but I knew I was pushing my luck with that stuff

It’s 3/4x3/4”.   Bent using a cheater pipe on it to see if I could cut the 1/2” with more force

Next one you build; try it with the bolt hole deeper into the body of the piece---it will help reduce it from springing out.  Also are you using a grade 8 bolt?

Yes it’s grade 8.   It works well for small stuff but your right. It tends to want to spread on heavier stuff. I’ll keep this in mind on the next build.  

With the 3/8 bar it was faster than hardy hot cut.  I’m thinking next one should be 1/2” bolt and like you said deeper so it holds its self straight with more support.   

You must be getting to know me well assuming I’m planning to build another.  This is just version 1.0.  

The blade holds up good just keeping the angle the blade was worn at.  I’m wondering if there is a edge angle I should be looking for. I’d like to be able to cut the leaf spring easily and faster than hot cut cause really if it’s not faster than it’s a waste of time

I'm sure that there is a "preferred angle" but that may have a bit to do with the alloy of the cutter as well.  I don't know where to check for that though---perhaps the old time machinist books or Practical Blacksmithing.   (Or chek what is used on Edward shears...)

Blacksmithing is an iterative process; both in forging things to finished shape and in making your own tools!   Please let us know when you get to the one that works so well you have to brag about it!
