    What did you do in the shop today?

    I made the dragon head into a key rack I can screw to the wall. Also started making a small wooden box with dovetail joinery today.

    Das, those are some great roses. I like the leaf details too. Frosty, do you have a photo of your vise rest? I'm not picturing it, but it sounds handy. I used mine today to make my first dragon head, and you're right about it slipping in the vise and scarring the shaft:

    Wow, that's a great fireplace screen. I made this crazy-looking jig today. It's roughly copied from one I saw in a Black Bear Forge video about forging a dragon head. It allows the head to be supported in the vise and be supported from below (at an angle) while chiseling the facial features. Hopefully it works, may have to reinforce the top lip. I used random stuff around the shop instead of buying the proper materials, but it was fun to practice welding.

    jewelers chasing/repousse hammer

    Thanks, horse. I already gave it away so I don't have a good size reference. The final face diameter is about 1 1/4" after grinding. It's on the large side for a chasing hammer, but not too bad.

    jewelers chasing/repousse hammer

    Thanks. It's hard to tell in the photos, but the face does have a slight crown. If I were making it for planishing or other body work, I would leave it harder.
  6. I made this jewelers chasing/repousse hammer for my Father's xmas gift. It started as a 1" diameter bar. I tapered one side to 3/4", then upset the other end to make a ~1.5" rivet-style head. I then punched and drifted the eye. Everything else was ground to shape, as it's very tricky to forge in the delicate fullers on a small hammer like this. It is heat treated, but tempered back to be fairly soft on the face to allow for better gripping of the chasing tool shanks. I turned the handle from apple wood, the wedges are jatoba. Shellac and renaissance wax finish.

    What did you do in the shop today?

    My neighbor stopped by with a 5' section of railroad track today. After he helped move it onto my property, he asked for a knife in exchange... couldn't really refuse, so I made a this quick spike knife. It has a piece of an old file forge-welded on for the cutting edge. Etched to show the transition from spike to file.
  8. I recently finished this pattern-welded integral bolster chef knife, can't wait to start using it. I started with 8 layers of 1080 and 15n20 steel, forge welded them together, twisted the whole mess as much as I could, then forged to a knife-ish shape before grinding. I did the heat treatment in the forge, quenching in preheated canola oil and tempering in my kitchen oven. My logo is electro-etched on there and then gold plated to look fancy. The handle is cocobolo with a mosaic pin and copper spacer.

    366 Hooks

    I got to see a lot of these in person a couple weeks back, very nice work. Matt is a great demonstrator too.

    Guillotine tool

    Hah, love the railroad spikes. Looks like it will work fine.

    What did you do in the shop today?

    My kanna blade made from cable and an old file is coming along. The pattern is showing up post-quench:

    Show me your Bottle Openers!

    I love the tentacle. Could you share more information about how it was forged?

    What did you do in the shop today?

    Making a small wood plane blade from several pieces of cable and an old file. Here is the scarf before the final forge weld:

    What did you do in the shop today?

    I used the punch dies in my guillotine tool for the first time yesterday, they work great. I made a handled hammer eye punch (punches making punches, kind of redundant). Also made an eye drift, forge-welded a hammer together (mild body with high carbon faces), and tried making another eye punch out of a RR spike but it kind of failed. This punch is made from flea market mystery steel, so who knows how well it will hold up. From previous forgings with it, I think it's maybe a lower or mid carbon steel. It does seem to harden in water, but not oil. Tooling I've made with it before has been a bit soft, so we'll see.

    Damascus with only hand hammers?

    I've done a few pattern welds, and I only have hand hammers. It can be done, but is an absolute bear to draw out when over 1" diameter... I would keep it 3/4 and below in the cross section. I like bandsaw/strapping damascus, I do it by first grinding the set off the teeth and grinding the black coating off the strapping. I did a fluxless weld on it with my latest billet and it worked well.
