    What did you do in the shop today?

    Ben, that has to be the prettiest hammer I've seen. I think using it will only make it more beautiful

    My first set

    Scotty your OP did not ask for advice ore invite comment on your work. As has been pointed out to me in the past, with so many viewers, we can't count on them all being as smart as you. the old timers feel obligated to point out things that are dangerous, if not for your benefit, for others. I like to show respect to the craft by doing it as safely as I can. Do you seek critique of your work?
  3. Glenn perhaps you've had better luck with them than me. early in my research, I used their online info forms seeking info. basically saying that their specs were not clear in the cartridge applications and asking which offered protection from metal fume poisioning specifically that from welding corrigated steel. after a week I got no answer so asked again. to date, no response. my research continued and I'm now satisfied that P100 will do the trick. my specific application was to repair some galvanized antenna tower, so concentrations would not have been high anyway, but I wanted to be safe. I recall my dad having been dosed when I was a kid and I don't want it. MBForge. sure looks like rust to me.

    A buddy collects hammers. Not a smith though. has an antique 16 pound sledge that he has hanging on a bunch of deck screws. had to add more as the weight bent the originals. I knocked out a hammer hanger for him.
  6. the respirators won't help with co2 build up. Did you mean CO? they won't help with that either. I think it is a good practice to not forge things that produce metal fume hazards. Zinc on galvanized being the one I have heard of quite a lot. My understanding is that the P100 standard is that it will stop 99.7% of particulate that is .3 microns or larger. I am not an expert but have read on the subject. Galvanized zinc coatings vaporize at forging and welding temps when it does, it immediately combines with oxygen and makes zinc oxide which is a white powder. breathing it gives you metal fume poisoning that you don't want. From my study all the particulate from this process is in the 5 micron range and NIOSH rates p100 possibly others to be used to prevent MFP. Don't know that respirator, but most of the good ones have some sort of end of life indicator. the ones that don't rely on some chemical reaction do do their job are really filters that are good until they get plugged.

    New to Forging

    sections here gas forges 101 and burners 101. In the FB page Blacksmithing for beginners is a files section that has a scholarly build of a gas forge that is pretty good except for a couple things we could discuss after you read it. If you are up for the build, I'd say you can build a better forge than typically comes from most makers for far less. I think I have about 240 in mine. good luck. Good to post your location in your profile.

    thanks Jen. that is useful info. I was planning on epoxying them in, but I might drill them through and do the traditional install. I have enough tang to draw it out enough to do that.

    I like that logo.

    made some handles for a draw knife I'm making. and I learned that 36 grit belts will take off a knuckle like it's not even there!
