    seeking advice on my burner

    Without seeing it, and given that I'm really a forced air guy, I'm betting that the orifice is too large, and/or, you don't have enough gas pressure. We see this a lot, someone will come and say "I built this and it's just like X, except that I changed all of these things. Why doesn't it work?" Venturi burners are a bit fussy, and tiny things can cause them to not function. It's a hard thing to do with scrounged pieces. Once you get it running it will be stable, but it's going to pretty hard to diagnose via the internet. It also looks to me that your injector is not dead straight into the throat, and that might cause issues. Perhaps one of the more experienced Venturi guy will weigh in. Geoff

    Good inexpensive wood rasp set?

    Good and inexpensive......hmmmmm.........you can have good or you can have inexpensive, but the two together, that is a unicorn. I like a "four-in-hand", but I had a cheap one that I had to throw away, none of the faces would cut. I have a cheap set of HF rasps and I think they are way to aggressive for the way I want to use them. They just gouge holes in things. My advice is to pay a little more to get a known brand rather than buy a bunch of cheap ones, struggle with them, thrown them away, and buy the better ones later on. Often paying a bit more for good quality is the cheapest route. g

    Axe question.

    Be sure to block up the ends of the forge, it will heat faster. You need an exit out each end (venturis are fussy about back pressure) so you need to balance flow through and access against holding the heat. A pile of fire brick works just fine. Breaking down big stock is a chore by hand. I try to think of ways to do that without using all of my strength for the day. Yes, I have a hammer and press, but I still think that way. Keep us informed as to your progress. g

    Help with Kris hilt design

    There is a ton of variation that I'm seeing. Many of them have a separate steel/iron guard/spacer, some of which seem to be held on by silver/copper/bronze "straps". There also seems to be a feature which might be a stylized garuda Geoff

    Help with Kris hilt design

    This is a form that has invaded my design head space, if that makes any sense. Does anyone here have images of Kris (as a generic term) with the hilt parts dismounted? You can see from this one that the blade and hilt are 2 pieces, held together with a pair of "straps". Any insight into the notches and such would also be helpful. Thanks Geoff

    Axe question.

    I realize the you already have steel, and perhaps the practice of welding the bit is part of why you are doing this, but..... Why not just start with a piece of hardenable steel 1 inch square? 5160, 1080, 4140, would all be good choices. You could also forge a nice thrower from a small sledge hammer, which saves you the trouble of forging an eye. As for your round stock. Slice a round and forge this Just some thoughts for you. Geoff

    heat treating ulu's made from saw blades

    Did you do a trad single sided grind, that will amplify the tendency to warp. You could try grinding them after you HT them. You might also try binding several of them into a stack and HT'ing the whole thing, the extra mass may help, or you could clamp them between two pieces of mild and then doing the HT. g

    I think this is called a cricket, this is a foot powered version

    New power hammer design/possible WIP

    They make for better drawing hammers because there is only one place in the stroke where the dies are parallel. It looks like the bottom one uses a piece of RR track as the helve. It always gives me a sad smile to see the JYH vid. Neither Jack or Grant are with us any more. Geoff

    I needs some grinder help

    Ebay has tons of motors, and so do these guys. You don't say what HP you're looking for. If there are motor shops in your area, places where they service and rebuilt motors, that might be a good place to start. You don't need an old motor, but you may have to change up the mounts. g
