Hi Michael
 
I agree, one of my (former) hobbies was blacksmithing. It seems to me that many people spend a long time turning a big chunk of metal into a small chunk, when my immediate thought is to forge it. Cheaper, quicker, it would in many cases need finish machining to get the dimensions spot on, but not always.
 
regards

When I was in UK in 1984, stayed in Sheffield for a week or two, spent quite a bit of time at the museum at Kalam Island, the Blacksmith there was making pocket knives to order fo the visitors, and scalpels for the local vetrenarians. Ian S C

Any form of smokeless coal is fine with hand pumped bellows. You cant quite generate white heat for Damascus!
 
Makes me shudder when think of blacksmiths, anything will do.
Above forge was approx 3ft wide x 2ft deep floor standing, no one wanted to lite it and when someone did, all pop head round door and say "I'll have it after you."

Gunsmiths do this still alot. Very practical it is.

Like this Axelfilm

Stars off a forging then precisely filed up to within a thou then turned.

Thats a hand operated bellows made out of the sued/leather work apron we wouldnt wear.

I've done some very simple tasks; it isn';t as easy as it looks. Just about managed to forge an eye about 1/2" diameter on the end of a rod.

Hello everyone.

I thought you all might like to see some pictures of a set of full size boiler washout plug bridges that I forged a few years ago, for a 1925, 10 horse power Robey portable steam engine.

The bridges started out as 1 3/4" square steel.

Richard.

I have a small portable forge I made with firebricks on a workmate. The 4 side firebricks form a box which sits on a 3" thick firebrick base. The base sits on the workmate. Several long gear type hose clamps wrap around the bricks to hold the sides in place and steel brackets hold the sides down to the base. Fire area is roughly 6 x 10" and 4" deep. The bottom brick has a hole for a 1" pipe that acts like a tuyere. I use a steel mesh grate over it. Charcoal (lump, not briquet) is used as fuel. The air blast to the pipe is from an ex-dishwasher centrifugal blower in a metal housing, speed is controlled by a lamp dimmer. This forge is superb for small work, and I have since built a steel "stack" box over the bricks for work needing a deeper fire. Heat is not a problem - I had some 1/4 x 1 1/2" bar in last time I used it, and didn;t pay attention for a couple of minutes, with air blast full on. When I looked in, drips of molten iron were falling off the end.

Charcoal is plenty hot enough, cheap, available and quiet and has very little smoke and a pleasant smell. Works great for me for small forge work and for melting small amounts of aluminum and brass.

I have tried propane but found it noisy and expensive and not very hot. Have also used bituminous (blacksmith) coal and found it needed a lot of managing and was smoky and smelly when blast was off, but there was plenty of heat with the blast on, once the coal had coked for a while. Good bituminous coal is not easily available where I am and costs a small fortune.

Charcoal it is then.

Sounds like an MEW article would be very interesting about this, David?

Over here in Hungary it is Marcius tiszanort -Fifteenth March-(one of the two National public holidays) so all the old Magyar re-enactment mob were holding a ‘fair’ or a ‘fete’. One geezer was there dressed up in old Magyar togs. He was forging and selling miniature horse shoes.

He was hot forging these things. His forge was about the size of a phone book mounted on a folding table. It had three lumps of fire brick and was heated from below by bottled gas. It seemed to have coal in it but these were ceramic chips. The shoes were made of 3mm wire which was bent into a sort of horse shoe shape. These were piled on his forge. When one was red hot he chucked it onto an anvil and waked it with a large hammer and returned it to his hearth. The shoes were about 30mm across. Later on the now flattened bits were changed into horse shoe shapes with three taps of a smaller hammer job done 2000 Forints each ‘Uram (sir) –a fiver each-

Hello Stub Mandrel,

Thanks for the comment, it's appreciated,

Today I'm forging some pairs of blacksmiths tongs, I will put some pictures up later today,

I'll also put up a picture of the propane furnace that I made 15 years ago, that I've been using today to heat the steel to make the tongs.

Richard.

Here are the pictures of the blacksmiths tongs that I forged today, and also a picture of the propane furnace that I use.

Great stuff Richard, how about some articles on forging? I used to do a lot (not very well) when I had access to a small coke forge when we taught engineering metalwork in school. the kids loved the magic of shaping red hot steel (no wrought iron available by that time) as if it were plasticine.

A wonderful craft, largely disappearing, it needs passing on.

Best (impressed) regards

Terry
