    Cutting G10

    I use vertical metal bandsaw using Lenox variable pitch 14-18 TPI, bimetal blade Chomps right through G10, scales / liners, no problem.

    TUS Stencil Cracks & finger nail polish?

    Huh, ... and I thought phone books were used by knife makers as a convenient source of paper for testing edge sharpness. The last pay phone I saw in Montana was in Cooke City and it had instructions on how to insert coins and push the buttons! Thanks for the tip - I'll begin storing my...

    TUS Stencil Cracks & finger nail polish?

    Nick: Perhaps my problem is not using the neutralizer solution that came with the power supply. I've been using Windex instead. Interestingly, the guy from TUS said that shouldn't make any difference, and that my issue was simply bending the stencil too much.

    TUS Stencil Cracks & finger nail polish?

    Thanks Ed, great comments. As you suggested, I have been "degassing" the stencil process by placing the etch pad 3-5 seconds on the stencil and then lifting. I have varied the number of pad applications from 10 to 30 during the etching process to see how much depth is achieved in the image...

    TUS Stencil Cracks & finger nail polish?

    After less than a dozen applications my stencils from TUS are developing hair line cracks aground the image. Those cracks show up on the steel as small spider web lines around the image. I'm using a Personalizer Plus typically set at 3.5-4 and do a 2 step cycle, first etching then marking. I...

    Chemistry help - Acid Etching

    Ah, indeed, I did ask a dumb question - I didn't realize that you're etching damascus. That makes sense.

    Chemistry help - Acid Etching

    Not that I know anything about etching stainless.... but, why 18%. Wouldn't 36% etch perhaps twice as fast? And... pardon me for the dumb question, why are you etching the stainless steel?

    Ever need 3 hands?

    Duh! Why didn't I think of that? Great tip.

    Metal Progression - What's Next After 1084?

    Help me understand this. I assume the upper piece is the 80CrV2. Are you saying that you were able to get better grain structure (smaller grain) in the 80CrV2 because you used an oven to HT that sample -- and that because the 1075 was HT'd in a forge it resulted in larger grain structure?

    Metal Progression - What's Next After 1084?

    Kevin, thank you for such a thorough answer, very helpful. Could you elablorate on what to look for in a "proper" HT grain structure? I've heat treated some 1084 sample pieces and bent them until they broke. I saw the difference in the bending angle before the samples fractured. But, as I...

    Metal Progression - What's Next After 1084?

    I got a dumb follow-on question (one of many). I've now heat treated a bunch of 1084 and have made some tooling with O1. It all seems to harden adequately - but, how do I know that I've got the process optimized? For instance, I follow all the necessary steips for heat treating 1084 - I...

    KMG 3 speed or variable

    For years I held off getting VFDs for my equipment. Finally I tried a KBAC drive on my lathe and within a year I added 2 more, 1 ea to my mill and drill press. And I now have my 4th KBAC unit on my 2x72 grinder. I say all that to reinforce how much value i get using (high quality) variable...

    Epoxies and unheated shops

    I've found using a red colored heat lamp lets the epoxy set up nicely, though I'm careful not to get it too hot - just warm to the touch. Also, BTW, in the winter I never let my shop get below 50, and I'm usually comfortable working in the mid 60s. I feel that high temperature swings can lead...

    Metal Progression - What's Next After 1084?

    As a beginner knife maker, I've been using 1084 steel. I think I've got the heat treatment figured out, thanks to Kevin Cashen's DVD and the amazing information on this forum. I'm now interested in exploring other high carbon steel alloys. I want to stay with high carbon steel since I don't...

    Hello From Montana

    What a hoot! You guys are funny. I must say, this the warmest welcome I've ever had on any forum. You sound like a bunch of really nice guys... the sort I'd like to get ro know over a few beers. Beyond knife making, I sense there are a lot of stories to be told. Bob

    G/Flex Expoxy Bond

    What great information, thanks. But, oh my, sorry for stirring up such controversy on my first posting on this forum. I feel like I kicked the hornets nest. I had no idea that gluing on handles is this sensitive. However, thanks to you'all I've learned a LOT, particularly about AcraGlas...
