  1. Nobody's doubting the science, but speaking for myself I would rather have science and opinion presented at a respectable distance from one another.
  2. I'd love to read the peer reviewed studies on the difference in performance between optimally HT'd 1080 and 52100 in the application for which you used them. Or are your statements perhaps more opinion based?
  3. I will second this. It is a meme that I believe originated on Kevin Cashen's site, and is repeated continually, often almost verbatim across the internet. Give a novice 1080 and it is very possible or even likely that they will produce a knife with enlarged grain structure. I've seen that many times. It can also be prone to warping. O1, on the other hand, is ubiquitous for a reason, and except through utterly egregious mishandling it is very easy to produce a hard knife with fine grain that is relatively stable in the quench. It is the Ron Jeremy of steels.

    Ever thought about selling blade blanks?

    I know what you mean about not enjoying handling knives, but the more you do it, the better and faster you get, and the better and faster you get, the more you enjoy it. I don't know how far along you are on your knifemaking career, but I think it's worth putting the hours in making and fitting handles, and indeed practicing and honing your skills in all aspects of the trade, until you have a sound reason to do otherwise.

    nickel carbon stop

    I would be very eager to hear any further thoughts you might have on the matter Jerrod. There are notions floating about in the knife making world whose origins I sometimes wonder about.

    nickel carbon stop

    In the instances I'm thinking of, the use of pure nickel was stated, but my fairly loosely held belief that carbon migration happened is circumstantial, if that is the right turn of phrase. I have also not used nickel for this purpose myself, so my authority on the subject is nonexistent, except that I am quite familiar with what carbon migration/diffusion looks like. I figured, like everything, given time and temperature the carbon will find a way to a state of entropy, and that to whatever degree nickel is effective, it is not absolutely effective.

    nickel carbon stop

    Thanks Alan. I have read the same, and yet I see many pictures (mostly on instagram) where nickel has been used and where the characteristic shadow of carbon migration can be seen. Perhaps it is something else? Nickel migration? Ha ha.
  8. I read that a layer of nickel placed between the cladding and core of a laminated knife acts as a stop to carbon migration. Can anyone tell me to what extent is this true? I ask because I see lots of pictures of sanmai with a layer of nickel, almost all of which display, to a greater or lesser extent, the "shadow" that carbon migration throws on both sides of the weld.

    Forge & cottage available, UK

    I hope it's okay to post this here; Having been the resident smith for the last 7 years, I am relinquishing the lease of the old forge in the village of Didbrook, GL54, and the landlord is very interested in maintaining the property as a forge. The lease is for the forge, the adjoining 3 bedroom cottage, a sizeable shed (bigger than the forge, but no electricity or water), some small outbuildings, including a pig house, and approximately 2 acres of orchard/garden. It is located on the Stanway Estate, in a very charming part of the north Cotswolds, 5 minutes outside Winchcombe in northern Gloucestershire. The property is quite large, and would suit someone who is interested in perhaps keeping a few sheep, or a horse, or a small holding of some kind. If this might be of interest to you or anyone you know, please contact me to discuss and/or I can put you in touch with the landlord, or feel free to contact him directly yourself. Please contact me at; didbrookforge@gmail.com Or contact the landlord, Lord Wemyss, directly; http://www.stanwayfountain.co.uk (there is a phone number)

    A Sword Fit For a King

    There are photos showing the rough ground and etched blade toward the end of the thread I linked. To my knowledge it was the first and perhaps the only successful attempt to recreate the pattern (or at least a "proof of concept" for the most significant elements) since the original was forged in the 8th century. Jesus' effort was a different method of construction to the original. I don't believe he was going for a strict reconstruction. Edit; Patrick Barta has also recreated the Vehmaa sword. If you aren't familiar with his work, he is, in my opinion, one of the foremost smiths recreating these kinds of swords.

    Today's lesson

    Today's lesson; Do not arc weld when you have anti-scale compound all over your hands. Especially if you are one of those idiots who welds without gloves. The graphite it contains works as a wonderful conductor for electricity. Bzzzzzzt!
  12. Welded on bolsters? That's hardcore! *begins slow clap*
  13. Your bearings would presumably be mounted on the body of your machine or on their own pillow blocks. Whether the bearings are mounted on the spindle or on your contact wheel I guess depends on whether you want your contact wheel to be your drive wheel (as with the ones you have, I guess).

    Sharpening the scandi grind

    Perhaps, but as long as we can disagree in a civil manner my (many and various) personality flaws shouldn't really matter too much.
