    PID Controlled Tempering Ovens

    I wouldn't rely on standard oven temperature controllers. Tempering temperatures need to be held to much closer tolerances than conventional oven controllers offer. I converted an old pawn shop table top oven & added a general use, PID controller (plug&play) from Aubers...

    Electro etching machine recommendation

    Had I seen that Welch power supply I would have purchased it before the Personalizer. That power supply is totally adequate for etching, plus useful as a general AC/DC supply, with a meter. There's a used unit on Ebay for $50.

    Electro etching machine recommendation

    I've been using the Personalizer Plus for several years and it seems to work good. It doesn't seem to lack power to get sufficient etch depth. When my logo isn't of good quality I think it's due to poor cleaning/surface prep or a clogged stencil.

    Arctic Air Mass

    You might consider getting some Boeshield T9 for rust protection, and some Rust Free for rust removal. Works great.

    Arctic Air Mass

    We use propane for both the house and shop. The house uses in-floor heating, the shop has an overhead space heater. We set the house at 68 and last night it had a hard time keeping up. I have the shop set at min 55 and bump it to low 60's when I'm working. We're used to -20s for most winters...

    Aluminum Quench Blocks, Will This Work?

    It seems there are 2 approaches to quenching with aluminum - 1) apply little to no added pressure than the block weight, or 2) apply added pressure with some kind of clamping. In both methods compressed air helps the heat transfer. Tracy has a long video on quenching stainless blades in which...

    Aluminum Quench Blocks, Will This Work?

    I'm setting up to heat treat stainless steel. I dug around in my junk pile and found 2 blocks that seem like they would work for most of my knife sizes. Rather than building some kind of vice clamp arrangement, I'm thinking that the weight of the blocks should be adequate for heat transfer...
