:s11798: Might as well have some fireworks as well. Getting close to Fourth of July

I did some research on propylene glycol. I have no knowledge on di-propylene glycol. Propylene glycol is unsed in topical and internal medications. According to chemical literature propylene glycol boils at 371 degrees F and poses no inhalation hazard. From what I can tell from the...

Thanks for the information Peter.

I love it!

If I can make an excellent quenchant for less than half what I would have to pay for one that would be a win for me. Besides that it gives me a chance to use the chemistry I learned. I think the first one I will try will be some propylene glycol 50:50 with water to heat treat some W-2. I am...

Kevin, have you tried any of these quenchants that were listed on the links you posted?

Well I don't know. I have never heated it that hot. I will do some research and find out about it's stability in high heat.

Really nice knife and sheath Wade. They just keep getting better and better.

I am a pharmaceutical chemist. Not to be confused with the pharmacist that just counts and pours medication. We compound medications for patients with specific needs. I was making some medication and got to thinking about things that could possibly be used as a quenchant. Propylene...

Thanks guys. Stag handled knives are real popular here.

Did you differentially heat treat the blade? Put clay on the spine or heat the spine after heat treat? You are not going to get much flex without a differential heat treat I don't think. Maybe some of the experts can comment on this.

I use O-1 a lot. I have found that you can't skip any grits. If you do you will get those scratches. If scratches show up I drop back one level say from 400 back to 320 grit. Then work forward again. When I am hand sanding I use Mobil One oil. It works. You can do a search and see more...

Awesome work Calvin

Three antler handled knives I just finished. Steel is 1/8" O-1 Tool Steel. Guards and Butt Caps are Brass.

I get the DuraCoat from Brownells http://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/paint-finishes/air-cure-non-aerosol-paints/duracoat-paints-prod44374.aspx Item # 100-007-936WB. You mix the paint with the activator and a small amount of their thinner. I spray it with an...

Really nice!!!

Knives are made from 1/4" O-1 tool steel. Blades are flat ground with a distal taper. Blades are differentially heat treated. Blades are painted with DuraCoat flat black. Scales are carved black on black micarta. Spec Ops sheath. I know, there is only one sheath. One of the guys has a sheath.

I like everything about it. Really nice!

Awesome as always Nick. I love your work

Awesome!!!!!!
