Well it finally got here. First heat is empty run up to 1500 degrees and hold for 10 minutes. I've programmed 4 different recipes for different steels. Now I'll be able to do more than 1 at a time. This will be a game changer.
Max temp is 2400 degrees. It could cook 1 slice is seconds. I've got to say it is insulated VERY good. Yesterday when it was at 1500 degrees the top you could hold your hand on, the sides were hotter as the heating coils are on the sides.
I heat treated my first batch of knives today. Since there is a learning curve I did 4 mini hunters made from 1095, with the price of stainless I didn't want to take a chance of messing that up. Got to say this heat treat oven is pretty slick. I can monitor it from my phone, I can also program a delay start. Load it up the night before set the timer to start an hour before I get up and presto. It even has a function to tell me the cost of the latest heat treat, I enter my electric cost and it does the rest. There is even more but I haven't dug that far into it yet. A couple of stainless blades will be next.
Here's a set that was picked up today. A guy I use to work with had them made for his son & grandson who is 13. The grandson shot his first bear this year. The handles are made from the bears leg bone & have a shot gun shell embedded in the end. The display was made to hold both knives and when the grandson gets his own place it can be cut in half for his knife. That was made from a piece of Carl's, black birch and a piece of leg bone.
This old root burl has been laying in the yard for many years. The wife finally said it had to go, so knife handles here I come. I think its a maple root burl, whatever it is, it's hard. My compound saw didn't go all the way through so the hand saw was dug out to finish it. After looking it over to get the most from it i made a few cuts. The wife has already claimed the first knife handle from it. There was no sanding done after I cut it open. I just sprayed some mineral spirits on to get the grain to pop. Going to make a pretty nice handle. But it's more then likely going to be over a month before I get back to it.
I'm assuming your talking about the voids in the burl. I have several different options that I use, depending on the size. They ranges from something as simple as a CA glue & activator (either spray or ultra violet), small epoxy mix and most complicated stabilize the entire piece with heat curable resin and vacuum tank. I just finished an oak burl handle that has several small holes. CA & activator sand smooth and you would never know they were there. The stuff I use is medical/industrial grade. I figure if it will hold a filling in a tooth or a cap on a tooth it's good enough for a knife handle.
^^^ Fun story on the wood for those scales. I had cut, dried, and split wood to make a couple of self bows. They didn't turn out how I wanted so I cut them up and made door pulls out of them, and sent the rest to tooln. He made great use of the opportunity and crafted some beautiful knives! The dude is a natural born knife maker!
Tooln message me your shipping address I’ll ship u some hedge and other scale wood I have laying around some will likely be interesting stuff is 3/4 thick material thick enough for you to split a set of scales out of?
