    Bulldog 3 Ton Arbor Press

    Anyone have experience preventing de-carb during HT?

    It's 1.75kW, 120V and it takes approximately 30 minute to come up to 900C. Torin...

    Anyone have experience preventing de-carb during HT?

    50' of Precision Brand 321 Too Wrap Foil was received yesterday. I also have some 641 and 304 on the way now, due to arrive Friday. The sales guy said 641 has a greater temperature range and suggested it, over the 304, for use with O1 but couldn't explain to me why. Now I have both to try out...

    Anyone have experience preventing de-carb during HT?

    I'm looking into ATP-304. Supposedly ATP-641 is for stainless and ATP-304 is for tool steel. Based on your statement above, they're probably all the same. But I have to find a Canadian supplier for ATP-304, so working on that too. Torin...

    Anyone have experience preventing de-carb during HT?

    Acquired an electric muffle furnace for heat-treating and looking to shoot the breeze with anyone who has experience keeping A2 and O1 parts from de-carbing during the HT process. I just bought 50' of 321 stainless foil (arrives next week) but am also thinking enveloping in clay with a sprinkle...

    Sine Plate Roll Pin Enagement

    Thanks - it was too good to pass up, even if it ended up in worse condition, it would still be worth $60. I was quite fortunate. Something is going on in Windsor... perhaps a major manufacturer closed, or something, because suddenly Kijiji is filled with all sorts of precision tools. I've got...

    Sine Plate Roll Pin Enagement

    Janger, it didn't take very long at all to draft those up. 20 ~ 30 minutes, so nothing lost. I don't know how many cad designs I've come up with only to abandon them because the design wasn't viable, moved on to other projects... if I had a nickel for every cad drawing... The grinder is, I...

    Sine Plate Roll Pin Enagement

    I'm so ashamed... after all this talk of making my own sine plate, investigating different designs, drawing up CAD models, and even pricing out metal, I saw this on Facebook: Facebook Find Yes, indeed, that is a Suburban 6x6 "SineSet" sine plate. He asked $60 for both the sine plate and...

    Atlas 618 "Armature Lathe"

    I said .075 (which I'm sure is what you meant to type), and it was aluminum. He dialed it down to .06" (.03 per side) and the lathe was able to maintain the cut without stalling.
