I have looked all over that thing, but I have not been able to located the RPM anywhere.
I dont know if it will help, but it is only 2 years old and it is the plastic case $99 model sold at LOWES.
I just cut out another blade out of a saw blade with a dremel tool. That is the only part of knifemaking that I really dont like. Is it any easier to cut a blade out of annealed 1080 stock?
I dont anneal the whole saw blade before I cut one out. I cut out the blade and then anneal, bevel,shape and then re harden.
I hope to build a knife from some stock from a knife supplier one day. I have used up 2 1/2 saw blades so far. I have 2 1/2 more to go before I am out of circular saw blades. I need the practice before I buy some 1080 from a supplier.
However, I still will use any saw blade I can get my hands on. I get a trip out of making a knife out of an old saw blade and old black walnut that I have from a 80 year old barn that was torn down.
Its nice to see rusty tarnished metal and weathered wood that was considered junk to become something pleasing to the eye.
