Pappy:
I use 50 1000  thick band saw blades to make mine.I just put slots at the bottom.I wouldn't
mind drilling the holes to attach it but it is hard to drill because of the temper in the blade.These are about 150 grains but you can fool around with the size just a little and get the weight up or down to what ever you want fairly easy. :)

I use the 7 1/4" saw blades for these.  I heat them up bright red to take the temper out for drilling the holes and bevel the edges, then heat terat and temper them back to about RC 50 - 55.  The bigger the holes, the more likely they will bend.

Auggie:
What do you qwench them in,what kind of oil?

madcrow:
I heat treat to about 1500 degrees F, quench in cooking oil and temper at around 550 for 1 hour.  After I quench, I wipe the metal down with paper towels, otherwise, while they are in they oven, the layer of oil turns black and is very sticky.  It is a pain to get off.

Auggie:
My grandfather used to keep a bucket of old oil and put all his filings into it,said it helped the metal in the process of heat treat.Always wondered about that.
