  1. a friend has several machines for making rings, some hand operated and some hand, its not hard.

    3 rollers, the middle one moves and at least 2 of them driven by a chain drive, adjust the middle roller with a small bottle jack, you can roll a 20 foot length is about 2 mins by hand easily.

     

    I have thicker stuff done on an old lathe sometimes

     

    if just bending them round a former by hand it is easier to do it cold and the scale flakes off

  2. doing work with you hands will always have value, other jobs come and go, at the moment we are undervalued but when their are problems we can sort them out.

     

    in the long term things will always need to be made or repaired, most things are made to last less and less but some people will always value quality

  3. the glass like stuff is clinker, you get that when you burn metal, when you heat the metal and it is giving off little sparks that shows it is too hot and you have burnt it, it is the cause of the holes you have.

     

    you need to remove any clinker as it will make a mess of your work.

     

    in your forge there are different zones, assuming it is a bottom blast, close to the bottom the fire is mostly oxidizing ( more air than fuel ) here metal will burn away easily, above that the fire is more neutral and near the top it is more carburising ( more fuel than air ).

    you should be using the upper parts of the fire more and watch for the metal getting too hot

  4. was part of a team working on restoring an orangery, had hundreds of steel screws in cast iron, others tried and got 1 in 10, destroying the rest, I got about 98% out with no problems.

    placed an 8mm  ( 5/16 ) not on the screw head or top of the tread if the head had gone and filled it with the mig, kept a spanner ready to turn the nut whilst it was still glowing, back and forth a few times and then out

  5. yes they work fine on the forges I sell, I also often have the blowers in stock.

    the better blowers we use are called side channel blowers and are quieter and made to run forever, chinese plastic bouncy castles blowers will not last long with everyday use

  6. here are some of the ones I supply, from 5" od to 11" aprox

    I also have a couple of big shallow ones IIRC 17" dia and 11/2" deep made from 1" thick stainless, the hole in the middle has been ground now where a fitting was welded in place, 1/2" thick at the edge and 1" at the middle

  7. was going to use a footswitch but as so much of the things I suddenly need to make another batch of are the same 2 items and each will need x seconds to heat being able to switch it to a fixed time may be useful, sort of press footswitch and release for x seconds but also be able to press and hold for other stuff.

     

    the design im building has virtually no controls on it and uses a phase locked loop.

     

    yes I will make it easy to change coils

  8. the unit i am looking at was aimed at 70khz but turned out to be 66khz, as most of my work is the 1/2" i would make coils that are best for that size but I would have bigger for other stuff.

     

    in the shop at the moment we have 14 coke forges so im not short of something for bigger jobs ;) 

    one reason for 3kw is this is what we get from a normal  wall socket here in the uk, in the shop we have bigger including a lot of 415v 3 phase at 32a per phase but if it plugs into the normal domestic sockets it can be used anywhere.

    looking for sources of the components now, have all the major ones sorted.
