Did a little bit on the forge today
I pulled out some of my smithing gear today and had a go at annealing some cheap files, I want to see how they will go as a plane makers float.
From what I have read they were made from old files by the plane makers sometimes.
After heating the files up quite bright I slid then into the bucket of saw shavings, and put a lid on it. 6 hours later they are still to hot to pick up with bare hands.
At about the 3.5 hour point I took one out and put a bit of water on it , it sizzeled away , I left in on the wooden bench for five minutes , then dipped it in some water, I did a test and hammered it on the face of the anvil, the metal deformed, which is a good sign , the non annealed files crack like glass .
When I held the end of the test file half an inch over the edge of the anvil and gave it a whack ,the half inch snapped off. Im hoping the tool will hold an edge in its annealed state, its not a fine edge like a woodwoking chisel at 25 degrees, with a guess its more like 35 degrees. and its pushed not hit. Any one have any opinions opinions ?
Apart from that ,I want to put the missing hood back on my forge one day . like the one in the drawing.
And the one to four blower set up with the gate is how I have been pumping the air to the fire .
I drag all this out of the shed when I want it , exept the forge lives under a sheet of tin out side on my favorite {messy}side of the house.

Hi DJ,
My forge has a hand cranked blower, that is what you are calling the other blower , I think ? , it's the one with the hand crank.
The one with the electric motor I put up high on a stand and made the air gate which gets connected to the original blower through a length of down pipe. the air just goes through the original without me touching it.

Thanks Rob, that explanation and pic clears it all up.
I've got a Dawn blower that I want to use for a forge when I get around to making a new one to replace my small home made one.Cheers

Thanks DJ ,I look forward to seeing it , I like the old gear .
How are you thinking of building your new forge, whats the fire going to sit in ?
I built one which I use at work once every few years. I made it from 150mm of the bottom of a 44 gal drum in which I used a type of cement used in fireplaces , cant remember the name of it. It works pretty good but it's a dam heavy thing to move around.
I have been thinking of another ,a light weight, powered by an Electrolux vacuum cleaner, same way I supplied the heavy one with air. unless there is a better way ??
I want to contain the vac underneath , covered, have the fire a bit higher up , wheels would be good as well.
I'm just enjoying dreaming it up ATM

Hi Rob
Heres the pics of the blower I have. Says 3B on the side of it.

And this is one of my homemade one which cobbled together from scrap. Blower is from a clothes dryer. I had a 8mm plate with holes drilled in it that sat on some 25mm RHS for the coke to sit on in the base of it.

Nice blower and forge DJ . thanks for showing them.
So is the new forge that you are going to build be a bigger permanent one ?

Thanks Rob.
That is the plan, something that I can just fire up when the need arises and fit in some bigger equipment, since I built the cobbled together one I have branched out to owning earthmoving equipment and a crane truck. So a bigger forge would also allow me to heat pins, bushes etc for pressing work and also tempering old truck springs for tools etc.Cheers

Old truck springs, where do they turn up ?
I will have to go have a look at a truck wrecking yard around Dandenong somewhere. I find leaf springs off trailers sometimes and have a stash . and a few coil springs but it's all to small
I have been working with some vintage wood working machinery and they sometimes need a special large spanner hanging off them to use on some big nut for holding the cutter head on, and I like the old style spanners, like in the pictures.
It would be a nice project cutting them out with the oxy then grinding and refining in the forge.

I can get some for you if you like, my truck mechanic is just down the road from me and I'm sure he has a few laying around.

Forge design
It is great to see forges being built and used! There are many ways of building a forge, some better than others! This site is very good in explaining the pros and cons of different forge/firepot designs, Beautiful Iron
It has the design for a side draught sheet metal chimmey that is very good.

DJ, it would be good to know the thickness [ I would need at least 1/2 inch I think or more?] and how much he wants for them, if you ask when you see him next , thanks.
anglesmith, Thanks, good link that one you put up. bit hard to find things on it though, this must be the forge ? or the hood, not had time to read it yet.
Steel s-draft drawing
I have a book somwhere ,that shows an English forge which blows from the side and the tuyere [ just spent 5 minutes looking for that word] is water cooled , it runs through a tank.
Any one used a forge like that and what is the benefit of having it set up that way ?
Rob
