    Probably a bit of both!

    Bit different this one, another one of those ideas that has rattled around in my head for years. A wind powered stone polishing tumbler. Living remote north of Scotland, not many trees and constant sea breeze seemed like a good project. No disrespect to disabled badge holders, just happened to be the perfect rudder and it was on the skip! Made up from scrap bits, bike head tube/ bearings, bike hub, printer rollers, sign, bit of garage door arm, cutting of 8" drainage pipe & stop ends. Think i did pay for the stop ends, all else off the skip. Oh and made the propeller blad

    Nice stick midnight. I bet that thumb made the eyes water when you did it!

    Made up a couple of more pointy ones for detailed work. Thanks for the comments guys, sorry to disappoint you, not quite a Leonardo Da Vinci but they do work! Might try something a bit more 3d when i am not on my lunch break.

    Thanks guys, comments appreciated, makes it worthwhile posting it up if others enjoy it.

    Thanks kanny. It has been fun documenting my experiment and posting the info up. Hopefully others will have a go at making a DIY Sam Mai and can benefit from my trial & error thread. Midnight and others have been helpful in sharing info that has helped me in the process. Best way to learn is from others experience.

    Cheers midnight, i am quite pleased how it turned out especially as it was made up as i went along, but then again most stuff i make is! Just need to get round to making a sheath for it, like the look of those wet form ones, need to read up on that.

    Well finally got this one finished! Tried the acid dip, was a bit warm still when i dipped it as as you rightly said midnight in left a ridge, only in 10miniutes but worked faster than i expected! As there is not a lot of carbon in sight, by the time i got it honed up there wasn't much contrast showing so i decided i preferred the polished look. End capped wit a silver American Buffalo Nickle

    Fancied trying a bit of stone carving so made these tools up from a coil spring. Not tried tried them yet but it was fun making them.

    Yes it's his little sister wearing it but it is still really too big to be practical. More just an exercise to prove he could design a piece on paper then develop the idea and finally follow through with making it. He got an A for it anyway, think the teacher was a bit gob smacked, expected cardboard, string & sellotape ! But then like i said he more or less has lived in a shed full of tools since he was a nipper.

    Yeh can't keep him out of the shed, would happily live in there, chip off the old block, i was the same at that age, just comes in for food!

    Good idea that Gaff, you can make jewelry out of all sorts of stuff that is just scrap bits lying about. My boy just made this up for his nat 5 art assessment, mainly bits old hot water cylinder and heavy copper earth wire.

    Delayed again getting this finished. Actually the main reason was i couldn't decide to go with no guard on put a guard on. I preferred the look without a guard but it didn't feel right in my hand, sharp on the back corner of the blade. I played about with ideas but couldn't come up with anything i was happy with, so put it aside to let the old cogs in the back of my mind work on it for a while, eventually a light-bulb came on and i set to again yesterday. Came up with something that looks good and feels right. Forged up a bit of 6mm A4 stainless rod. Shaped it up Welded i

    Looks good gaff.

    Aye a Danforth would hold.

    That's my kind of anchor, made from recycled spring steel, far better than any mild stock you can buy, cracking idea Bogdan.
  17. GruffaloGriff
    Nice Job as always. Bargain price, tempted but too many knives as it is. Snap em up while you have the chance lads!
  18. GruffaloGriff
    Don't think mild will harden. Weld a web in.

    Nice job T.C real talent there.

    Cheers Midnight, bit more polishing yet but it is coming up nice. Got the acid now for the etch it says warm it up for faster results-assume a stainless pan would be ok and a plastic tray for doing the etch? "You have done your home work on this one !!" Not like me at all, usually just jump in with both feet Spent too much time on this one to muck it up now. "Iv never used hss so will follow your reading on it" Pm me your postal address midnight and i will send you a blank to play with next time i get the forge fired up, would be interesting to see what a pro makes of my DIY San Mai.

    Cheers sussex. Wouldn't have it standing in my sitting room but it will keep it going for a few more years in the boys fort until they grow out of it.......saying that at 42 i still haven't grown out of burning things yet!!!

    Tempering information for M2 HSS taken from here http://www.westyorkssteel.com/tool-steel/high-speed-steel/m2/ full PDDF data sheet top rh corner of page. Hardening Pre heat the steel in two steps; 450-500°C then 850-900°C. Then continue heating to the final hardening temperature of 1200-1250°C and ensure that the component is heated through. Care must be taken not to allow the component to remain too long at the hardening temperature. Quench in warm oil or brine. If quenching in brine allow the tools to equalize, then complete the quench in air. If quenching in oil remove the component fr

    Got a bit sidetracked with other things as you do but got back on to this today. Blade having 3 x non magnetic treated, now heated light cherry red. and quenched in Lydl's finest cooking oil Double tempered to bronze (held it for 10 miniutes before air cooling) then tried an edge but too hard to take a decent edge Tried a light blue temper and it takes and holds an edge unbelievably well. Carved up a chunk of 2" x 2" and it will still slice a piece of paper edge on held between finger & thumb.

    No baffles in the flue, just welded straight on to bottle. Do have a flap on a pivot in the bottom to control air flow. Felt a bit guilty about letting it rot so pulled it out yesterday and gave it a blast with the wire cup brush and welded a new hinge on as it had frozen up and broken, brass this time so should be fine outside, heated up and lashed on a coat of waste oil, firs fire will burn the excess off.
