    Very nice, Dave. There are a lot of people out there who simply cannot grasp how these can possibly be better than normal screw/gear adjusting hose clamps.

    I suspect most of them would appreciate these after making and using them a few times.

    I started putting together a torch cooler for my newly-acquired TIG welder, and realised I was going to have trouble making space for Jubilee (worm-drive) hose clamps and would need a lot of 'em, saw the ClampTite wire tool and though "I can make one of those" - it worked out pretty easily, a few holes drilled in some aluminium tube (clearance bore for 8mm all-threadalike) and a pair of slots angle-grindered, I DID have to buy a wingnut, though...

    Here it is in all its inglory, alongside the cooler's pressure-pulsation damper (I'm using a diaphragm pump)



    The business end - a piece of M12 all-threadalike Loctited in the drilled and tapped end of the tube, then the lot spun in a drill against the bench grinder, finally slitted with a 1mm cutting disc in the angle grinder:



    And... the end result, 0.8mm / 0.032" stainless lockwire on a clear PVC tube over an 8mm (5/16") hose barb,



    Crude, but very effective and I put it together in 15 minutes - delivery if I'd bought one would have been a few days!

    The company below is reproducing the SB grinding fixture with capacity to 1/2" square.
    Should help get a tool that cuts right the first time!

    the first project in the book "the shop wisdom of D. E. Johnson " is one of those grinding jigs. if you want to roll you own.

    I did have a thread talking about my issues with Nichrome wire, initally. I did not know about "surface load" at the time.

    I got a lot of my info from this guy's blog post, including my brick layout as I found the same bricks from a local pizza oven supply.

    http://dcknives.blogspot.ca/p/electric-forge.html

    I could do a bigger post with more pictures if it was wanted. My coil would greatly benefit from 2x the groove length so I could stretch it out longer, but by the time I was learning that I'd need kanthal and not nichrome, and that the surface load was way too high, there wasn't much I could do as the oven was glued together already.

    Another vote for a build thread on that, and especially a section on the controller. I've been wanting to build one like this myself, nice work!

    It wasn't too bad. About $100 for the brick, $60 for the flat bar and sheet metal, $30 for the heater wire, $30 for the timer unit, $12 for the big LED lamps, $15 for the power meter module. The rest of the stuff was in my junk bins and scraps from work.

    Nice. Good job you don't live near me! "You know your heat-treat oven..."!
    Everyone needs a surface grinder....and the space to put it *sigh* Pretty sure I'd need a divorce lawyer too if I tried to buy one anyway!

    I finished up my heat treating oven today. Learned some stuff partway through and had to rejigger it a bit, but it works, so far. Got it up to 950 C and it was still climbing, not sure just how far it can go.

    I hope to use it for case hardening mild steels and for through hardening and tempering tool steels.

    Seems like I'll be needing a surface grinder soon.
