You did a good job of nesting those blanks, but as Dr. McCoy would say, "Dammit, man, get yourself a portaband saw!!!"

Only after heat treatment. Before, you want to see as little sparks as possible. That's a sign you have annealed your steel properly.

I'm so glad I'm not the only one drilling holes and bashing things about!

One tip... although i have to say i dont think it is faster... it is less of a material waste... is a tip i got from a knifemaker Bertie Rietveld. He suggests grinding with a angle grinder the rear half or two thirds off most of your bimetal hacksaw blade... use cutting fluid and voila! A metal coping saw... i cut these out this morning... i have two blades a normal and reduced width one to save the reduced blade on the long straight sections... a sturdy hacksaw is a must though... two hacksaws would be better
I frequently leave only about 2mm between patterns and do 1/2" radii fairly easily... just saw as if using a coping saw or jewelers saw around a curve... slower progress plus side pressure and you have a curve... blades last quite long if you are somewhat mechanically sympathetic...

This mornings batch... and a cut out blade... obviously not one continuous cut, but not 20 small ones either... ready to finalise on the grinder... dont have pics of the sawblade though... think about 4mm blade except for the inch next to the blade eyes... and a gradual taper to do bit of stress relief...

Btw i looked at your photos again and i am not sure you would have gained much using this technique except avoide some drilling and swopped quite a bit of grinding for some sawing that is not that slow...
