I can only find PG 440C and ats 34.If you dont have a Surface Grinder, what is everyone using for their folder blades ? I would buy better steel if I could get it in PG. I currently use 440C for its price and PG.

PG is a good head start but you do have to grind on it to clean it up after heat treat and so on. It's not quite as PG after that.

Which means that if you start with something not PG that is close to the required size you can learn to grind it to the size you want on your belt sander and get pretty close that way, with practice.

Another way is to grind as little as possible to clean up the steel and make your blade. Now you have a finished blade of some oddball thickness. What I used to do at that point is adjust the thickness of my washers and/or the thickness of my back spacer to accomodate whatever thickness the blade turned out to be....

Yeah that was my issue. My first couple of tries I used non PG and it was way off of spec. I didnt have a grizzly then and it was a chore to get it close to the size of my back spacers. Somone mentioned using only PG and told me what SS PG back spacers he used so I started using those and the 440 PG.I need a few more under my belt I think before I start getting fancy steel. 440C is decent stuff.
thanks

Dave, sometimes I use two thin brass spacers on both sides of my regular back spacer to make up for a thicker blade. By varying the thickness of the pivot washers, the brass spacers, and the steel back spacer, there's usually a combination that works.

The thin brass shims on each side of the back spacer look neat and add interest.:gossip:

Dave,

Crucible is now selling PG CPM154 and S30V, thru their Arlington, Tx location. I just purchased three feet of each, 1/8" thk and picked them up myself.

You may want to check with them.

You said that you have a Grizzly I am assuming that you are talking mill. If so you can use a Cone rock from MSC get the 58 rockwell to do surfacing with or without a magnetic chuck. granted without will take you longer and you may loose some of the metal but it works very well, just take 2 to 3 thousands at a time the heat build up is minimal and even less with a little dawn mixed at 25% with water for a coolant. You'll find over time that you can get within 5 ten thousands on the surfacing.

Grizzly is my grinder.WISHHHHH I had a mill if you see a homeless one you can send him to Plano :)
