JHCC Posted January 28, 2018 Share Posted January 28, 2018 14 minutes ago, Gergely said: though I think when you welded the long seam holding together the angle iron and the base plate you either welded it too fast or with too low amperage. Also a bit more surface cleaning can help a lot. Travel speed too fast, actually; the amps were actually all the way up. I ground down to bare metal before welding, but only where the seams were to be. Definitely worth the time. Quote Link to comment Share on other sites More sharing options...

I've seen it and thought: how on earth got it a crack there?! But it's actually coming from the bending not from some cracking force. - Thank you!! And yes of course it has to go.

jlpservicesinc Posted January 28, 2018 Share Posted January 28, 2018 That is one of the most likely places to get a crack.. One of things that took me a lot of years to learn is. " Cracks happen in many places while forging, 90's, bosses, shoulders, etc, etc.. Difference between a good piece and a bad one is watching out for these kinds of things.. You'd be surprised just how many forgings have forging cracks or cold shuts.. Quote Link to comment Share on other sites More sharing options...

Hans Richter Posted January 29, 2018 Share Posted January 29, 2018 Finished the vice stand and give both (stand & vice) a paint job. Looking for a strategic position now to attach him to the concrete floor. Spoil all the moving parts of the vice with grease for a smooth functioning. Spend again a lot of time on deburring/slightly bevel all the parts before welding. What’s your opinion regarding deburring on all the parts you working on? The metal stockpile behind the vice will become a decent welding table this week. Cheers, Hans Quote Link to comment Share on other sites More sharing options...
ausfire Posted January 29, 2018 Share Posted January 29, 2018 Made a leaf-handle fire poker. I'm never totally confident with the fire weld after folding back the point. Sometimes takes and sometimes it's a bit dodgy. I've melted the short spike a couple of times. Seems to me that when the piece is deep in a charcoal fire you have to guess when it reaches welding temp - and it's a very fine line between hot enough and burnt. Anyway, I'll keep trying. Also made a shifty lizard. I like the tail on this one, because it's made from a piece of very heavily weathered rebar. Usually, tapering the tail from round bar is a bit onerous, but this one was already tapered for me. Nature lending a helping hand! Quote Link to comment Share on other sites More sharing options...

They always look perfect, so is it not the same process? Quote Link to comment Share on other sites More sharing options...

I used to fire weld the bull heads, but burned a lot of horns. I don't fire weld them any more, as with 12mm steel there is plenty of thickness in the fold. You just have to be a bit careful forging the flats for the eyes that you don't skew the head sideways. I my be wrong but I reckon it would be easier to fire weld in a propane forge where you can see the piece and remove it at the critical time.

JustAnotherViking Posted January 29, 2018 Share Posted January 29, 2018 Ah ok, thanks for clearing that up. Yeah, i'm also in the burned horn vs not properly welded camp (using coke forge). I need to make a new gas one so I can use it for welding as my current one is just soft fire bricks.. works great for normal forging, but eats through the bricks at welding temperature (also a complete waste of gas bringing up to and maintaining temp... not as efficient/heat reflective as castable refractory + coating) As well as the visibility, there is the added benefit of temperature control: the piece can only get as hot as the forge... keep the pressure/air mix at the right level for the task at hand, it stays constant... you're less likely to burn something if you forget to lift it out for a few minutes.

bubba682 Posted January 29, 2018 Share Posted January 29, 2018 I like the poker ausfire i got an order for 4 sets of of tools and stands anyway the poker pt is being difficult as well so im thinkin of sneakin some tig in at the fold or splittin the point and curlin it.My forge doesn't like flux so untill the spring when i get my shop extension done and new coal forge built i think im goin to cheat with some tig lol.

John in Oly, WA Posted January 29, 2018 Share Posted January 29, 2018 I worked on relining my forge this weekend. First go 'round, I had 1" kaowool and 2" of kastolite, and the kaowool got compressed putting in the kastolite. So I chipped it out, put in 2" of kaowool, rigidized it (something else I didn't do the first time 'round), and put in 1/2" of kastolite. Cast in a nozzle for the burner this time also. Looks pretty much the same, but expecting it to perform a bit better. The one pic I missed taking was the rigidized kaowool in the forge shell. You can kind of see it in the third pic as we're tamping in the kastolite between the kaowool and the mold plug. Quote Link to comment Share on other sites More sharing options...

Daswulf Posted January 30, 2018 Share Posted January 30, 2018 Hans, I believe that's called a cat pillow, not a Pekinese. Got a little time in the shop tonite. Toyed around with a few forge welds for fun. One will end up a fire poker. I have to say that over time these almost just seem to happen when I remember struggling severely and failing. ( must be all the reading up on here )thanks for that. also a leaf keychain and a goofed up ( but still sellable) horseshoe horse head heart( say that 5 times fast) to sell at work, since they have been bugging me to bring stuff in.

Stitch Posted January 30, 2018 Share Posted January 30, 2018 Beautiful work Das! Nice poker too, I really like your weld!! I was bored last night so I made a pallet buster for a friend of mine. He heats his shop with old pallets and I thought he would like a hand. That's my mini weld table in the post vise. Quote Link to comment Share on other sites More sharing options...
