    What to do when the number of knives exceeds quench capacity?

    I'm heat treating a number of knives using AEB-L with Alpha Knife Supply's HT recommendations. I want to do them (4 or 5 large blades) as one batch in the oven. Do any of you have experience extending the duration of the last heating hold point of 1975F? AKS recommends holding this last...

    Welding (cheap) Machines

    The interweb has a bunch of welder machine recommendations. One of my favorite guys is Jody Collier that has a ton of high quality videos on weldingtipandtricks.com. His advise addresses MIG /Stick and TIG. It boils down to how much you want to spend for the type of welding you'll do. More...

    Adding Argon to AEB-L HT Pouch

    I'll have go get my WD40 out of the boat. The only thing it'sgood for is spraying on fishing lures... and it works good for that! But I'll give the HT idea a try, that may be the second thing it's good for.

    Adding Argon to AEB-L HT Pouch

    Good questions. I've never had much decarb on AEB-L. But, depending on whether I used a paper insert (or how much paper), I would get varying degrees of black surface coating. That discoloration would grind off. The Argon gas seems to have eliminated the dark discoloration and added a...

    Adding Argon to AEB-L HT Pouch

    Using inert gas (Argon mostly) is a common feature with many HT ovens. The benefit is a reduction or elimination of surface scaling. I opted to not add that feature when I got a Paragon oven because filling the entire chamber with gas is costly and, in my opinion, doesn't make sense for my low...

    Lathe Drive Belt Replacement - Pt. 2 Details

    As requested, this posting describes the details of my initial posting outlining replacement of the flat drive belt on my lathe.

    Lathe Drive Belt Replacement - Pt. 1 General

    I finally replaced a very very old worn out drive belt on my lathe. There are a bunch of YouTube videos that describe disassembly of the lathe headstock and drive pulley to install a new belt. Another approach to replacing a belt is the use of connecting staples to join the ends, or lacing the...

    Mini Lathe - Good deal?

    Sean, here are some brief comments: Pluses: Seems to be in reasonable shape, relatively clean The Aloris style (OxA brand) quick change tool holder is helpful, has multiple attachments The four jaw scroll chuck looks good, Harlingen is a known brand The four jaw independent chuck can come in...

    opinions wanted.

    Here's my opinion: - fit and finish look good, - overall blade design reflects a more modernistic shape, which is an interesting style, - I like the rounded champher on the handle, However: - the handle extends out over the toe of the blade above the bottom of the plunge line, crearing...

    Mini Lathe - Good deal?

    Sean, just as a follow-up comment - that size and style lathe is mostly suitable for cutting softer material like brass, aluminum, wood, and small steel pieces, without much repeatable precision. There just isn't enough strength in the lathe bed (ways) to handle heavier material. However, for...

    Carbon chrome?

    I would guess it's just a casual way of saying it is some kind of stainless, perhaps used as marketing jargon. Any of the many variations of stainless steels will have some percentage of carbon and chrome in it. In general stainless steel will have a chrome content over 12%, or so. The term...

    Any simple way to guess steel type?

    My best advice is to search YT(or just a general internet search) on how to identify steel with a spark test. You'll find plenty of ways to test the steel for composition and hardness. But, unless you submit it for a formal composition analysis, you can only guess. What you bought is called...
