  1. Well, I finally decided to get back to sanding this fuller. It's a bit wonky, but will have to do. It's not bad for a first go at a forged fuller. The balde survived the quench just fine. No warping at all which surprised me. Here is a pic right after the first temper cycle: Next I evened up the shoulders a bit since they were still as forged, and started fitting the wax version of the guard. Investment casting has been on my to-do list for over 30 years. I've dabbled a couple of times, but never really did it right. KITH is giving me a chance to give it a good honest attempt.
  2. That's turning out nicely. Good job keeping the core steel centered!
  3. Almost all of the power tool brands are now owned by just a few conglomerates. Yard equipment is the same way. At one time I was quite the DeWalt and Porter Cable fanboy. No longer...
  4. Cool! Now you just need a strapping young lad to pretend he is a motor and move it up and down for you like that That hammer has come along quickly. I'm excited to see it run.
  5. Well now, that approach to shaping the guard is quite clever. That's definitely going in the rolodex of techniques...
  6. once a wizard gives it to a hobbit... Edit: I really should have added that is a really nice start on a blade no matter what you call it. @Bjorn Gylfason
  7. That pile of lama fuzz makes me sweat just looking at it. It was in the low 90s here today... I got this one heat treated today. It is 304 over W2. The W2 wouldn't harden in my 11 sec oil, so I did an interupted brine into oil quench. Somehow, it came out straight and in one piece!
  8. That's a lot of yarn! I'm certainly not complaining, just reflecting on the strange things I decide to do to amuse myself.
  9. Bladesmiths are weird people. I spend all that time and energy to weld twenty some odd pieces of steel together in a nice long bar just to cut it back up into twenty some of pieces again. I'm still not happy with it so I'm going to weld them all back together again. Do you know that scene in Cool Hand Luke where Luke keeps finding out his dirt is in the wrong place?
  10. Presses like that may be rated for 50 tons, but they are not intended to carry the dynamic loads that a forging press sees. You will be very dissatisfied with that as your base. I was able to get a local steel fabricator to make all of the heavy steel elements of mine for about $500. You might find a small shop that is willing to help out with the design. It cost me another $750 to buy all of the hydraulic components new.
  11. Yeah, the G1015 is the one I meant. I didn't catch that you were talking $AUD. You can get the G1015 for $500US or less when they run sales. I almost bought one for $475 about 4 years ago, but decided to save for something better. There are a number of DIY 2x72 plans out there if you can get the parts fabricated.
  12. At $500 you are within spitting distance of the Grizzly grinder which is probably going to serve you better. This is a rare time when I'll push back on Alan a bit. Most of the load for knife making will come from the 2" belt width times however much length in contact with the work. The rest of the belt isn't really adding that much load. I think a 2x36 running at 600W would feel just as weak as a 2x72 running that sized motor.
  13. A 3rd arm is just what you need to hold your pan-galactic gargle blaster while forging! Of course, you really need a 2nd head to do it right.
  14. I find it is easier to do the plunges without a chicken on my foot
  15. I'm not a pro machinist, but sometimes I act like one. Flatter angled drills, or slightly duller drills seems to help. Slow drill speed, and frequent pecking also help. Copper and lead are two materials I do not enjoy drilling.
  16. Thanks Niels. You're awesome!
  17. As long as you can adjust the tracking wheel enough to get the belt nearly centered either direction, I would just leave it alone. I wouldn't be very motivated to do much modification for reversing direction. Especially if your primary reverse use is slow speed.
  18. Sorry for the cliffhanger guys. Spinning my organization back up post Covid is taking up my personal time. Way too many details to get everyone back to work... This isn't perfect, but it is much better than any of my other attempts. I'll take it! Now I just need to remember which way to orient the parts in a 4-way weld for the explosion pattern...
  19. I don't have any experience with running my grinder in reverse, but I would expect to have to adjust the tracking if I did change directions. Tracking adjustments are basically trimming out all of the little bias forces at work in making the belt go around. Those forces are going to be different when running the other way.
  20. Looking good! I understand the slip-joint thing. I've been exploring that rabbit hole for about a year now. I'm curious about the construction of your slip-joints with the bone and wood bolsters. It looks like you made brass or bronze bushings to peen the pivot pin into. Do those go all the way through to the liner, or are they more like washers?
