    That should have read without the guard.

    For a moment I thought you had fond a nice bar where a certain Japanese hobbie happened!

    oh er misses.

    Once upon a time, after watching forged in fire I had a crazy idea to make a knife, as you do !!!.

    There is a truck repair place near me so acquired two complete leaf springs, they are bloody enormous. !!!

    Several hours with the big 9" grinder and I only just managed to cut a bit off.

    Stick it in the forge and after much time it was hardly hot.

    Conclusion is that these things can be done but not with the sort of home made kit us amateurs have

    Sounds defeatist. The whole idea is for us amateurs to show the professionals just what can be done with artful bodging.

    I'm cranking up the forge which I never really got around to tweaking in and then building a bending jig for the flypress.

    It ain't called a burke bar for nothin'. :D

    part of the problem in the use of the coal forge was being an amateur.

    It wasn't until id had a lesson from a master @julianthegypsy that I realised that you have to break the big lumps of coal into smaller bits so they "work" better

    Coal, hammer, hammer, coal. Tommy Cooper? :laughing:

    I prefer "Limited resources and minimal budget". Artful bodging is so vintage these days.

    I remember reading an account of an old blacksmiths apprenticeship, he reckoned he spent his first year crushing coke for the forges with a huge steel plate on the end of a pole, and by the end of it had arm muscles bigger than the reigning heavyweight champion of the world!

    Re. Grinder guards, keep an eye out for a Bosch blue one. The one on mine is great, it's held on by a lever clamp and can be spun/secured in moments no fuss. Not a new machine so is pretty old hat by now but still great. The screw tighten ones are really pants.

    There was big round lump on a long fork handle here that never seemed to have a job, but it looks like I've now got a coal breaker.. :D

    Are you going to use the 4 candles to heat the steel? ;)

    :scared:

    I thought you had a band saw with lubricant pump, set her going and walk off to do something else, perfectly safe.

    It's currently set up with a table for vertical cuts in wood. Too much of a faff to swap it over and I wasn't sure how my metal blade would fare against this tough old spring. Once I had it up to temperature, I figure it would anneal it a bit but getting it to temp has proved problematic!

    True story: a mate popped over to play with some toys in the workshop recently, grabbed this very angle grinder and started cutting. Soon as he did I cut the power and told him off for using it guardless. If looks could kill...

    Anyhow as it happens I did nick a finger but it was with a brand new flap wheel. Having a guard wouldn't have helped because I caught it at the sharp end where it would have been exposed anyway and it went through the glove before I heard my own scream. On the other hand, if I did have a guard fitted, it might easily have jammed my finger right in between the disk and the guard. That would have been a whole lot less fun.

    Nothing is ever perfectly safe, at least not in my workshop. It's a question of magnitude and sometimes having a "safety feature" present can disguise a dangerous situation so that instead of a few minor accidents, you're just saving up for one big one.

    Any how, to the flypress!

    I went through a number of iterations of design to come up with a solution based around materials on hand. Those tractor pins I bough off here look promising.

    I can use the holes to my advantage in retaining the pins and setting parallel, distance etc.

    A quick hack setup last night and I think I might even be good to go.

    Obviously it will still need heat (and I am tempted to try the Tig as suggested above) but even stone cold, it does look like it's working.
