Help with annealing A2
brian robertson replied to brian robertson's topic in Heat Treating Knives, Blades etc
I wish I could put my finger on what I did wrong with these 2 out of the 6. I didn't mark them so I don't know if these 2 are the first,last,middle or apart. What's weird is that the blade portions ground and polished exactly like the other 4. Not too hard, not soft. I suppose I could always epoxy them in their handles. -
Help with annealing A2
brian robertson replied to brian robertson's topic in Heat Treating Knives, Blades etc
I'm trying to do a salvage procedure if possible. The heat treat on the blade portion on these 2 are right on the money. I'm looking for a trick to anneal only the tangs. -
Help with annealing A2
brian robertson replied to brian robertson's topic in Heat Treating Knives, Blades etc
This A2 is an "air hardening only" steel in thin cross sections. These 2 tangs are so hard, they ate my 9/64th carbide bit and spit it back out,barely putting a mark on it. -
Recently forged 6 blades for hoof knives using 1/8"x3/4" A2. This is the third series of these blades over approx 5 yrs. The heat treat went well on 4 of the 6 blades. I don't think I did anything different from the past. On the other 2 blades the tangs are way to hard to drill for the pins. Any hope of spot annealing the tangs? Will this thin stock take a do over and perform well? Write it off as "the gods were angry"?

advice on air hammer please
brian robertson replied to r smith's topic in Power Hammers, Treadle Hammers, Olivers
If the dies aren't potmarked and the air cylinder/air lines aren't leaking and the guides aren't gone; there really isn't much that can be wrong with these hammers. Call Josh at Big Blu and ask about the new upgrade option. I did my 155 this fall and it's sweet. The additional airlines to/from the cylinder and the dual valves have really improved the performance and reduced some of the air consumption. It was worth the money for me.

Fake Candle Help ? Supplier
brian robertson replied to ironwolfforgeca's topic in Blacksmithing, General Discussion
I have used 1" white nylon dowel pins in place of candles in carriage lamps that are on display. These are available from industrrial supply houses. They look like the real deal. -
Freezing Propane Tanks. A Different Solution
brian robertson replied to maddog's topic in Gas Forges
I wasn't clear in my response. I know a frosting up tank is not a problem. The problems arise when everything between the tank and the burner is frosting up. -
Freezing Propane Tanks. A Different Solution
brian robertson replied to maddog's topic in Gas Forges
If you are "frosting up" everything every time you're running your gasser; you must have money to burn and are very,very lucky. Just because you have "gotten away" with this doesn't make it wise or safe. I've even seen horseshoers put their frosted up 20lb cylinder in front of a running gasser, because they pressure had dropped off. The frosting up occurs when you are pushing way more fuel than what your system was designed for. You can only burn so much propane in a enclosed space (your forge). If you excede that finite amount, the propane will them combust outside said enclosure; Your forge will Not heat your stock well but heat your work space and not very efficiently. Plus if you are frosting up, the excessive unburned propane will actually cause the temp inside your forge to drop off. The frosting up does damage to the rubber diaphragm and rubber hose and can initiate leaks at your fittings. Speak with any of the commercial forge manufacturers, any service worker in the propane industry or fire marshal. They'll all tell you it's a, bad thing -
Freezing Propane Tanks. A Different Solution
brian robertson replied to maddog's topic in Gas Forges
You are drawing too much propane at too high a pressure. The frosting is expensive in 2 ways: it damages the diaphragm in the regulator and it's a sign of too much unburned fuel. Dial back the psi until the forge get up to forging temp then only if you're going to be welding crank it up. Call Nc for recommended psi settings. -

Power Hammers and Wet Soils?
brian robertson replied to Crunch's topic in Power Hammers, Treadle Hammers, Olivers
First off, make something nice for each of your neighbors every so often; secondly don't run the hammer after 9pm or before 8am or on Sunday. I live on a 70ft deep clay layer (think of a bowl of jello), my former 50lb & 100lb Little Giants would rattle the dishes in the neighbors' china cabinets and the bases for those hammers were 2 & 4 yds concrete respectively. The 155 big blu hammer mounted on the 4yd base will also make the neighbors' dvd players skip. My engineer friend said the solution would be to drive pilings down to bedrock and set foundation on top of those. My solution: smooze your neighbors as best you can; it's alot cheaper. The litle old lady says, my forging makes her china sound like soft wind chimes and she likes it. The folks with the skipping dvd player said they shouldn't be waqtching so much tv anyway. So, it's all good... -
solid fuel experiments in a brake drum forge
brian robertson replied to pkrankow's topic in Solid Fuel Forges
L brand forge coke=no black nose boogers & gets big stock very HOT in a non oxidizing fire. -
I have found that brazing ring gears can be problematic. If allowed to heat or cool unevenly they will crack in new places. My successful repairs were preheated using an oven set at 450 f for atleast 1 hr, support the pieces in a bolt on frame to maintain proper alignment, laid on a 2" blanket of Kao wool, brazed, returned to the oven rewrapped in kao wool and slowly allowed to cool down over 3 to 6 hrs depending on thickness. I've brazed parts for pumps, steam engines, farm impliments and tractors this way no call backs to date.
