    I won't be able to make it this year....


    But I should be able to next!

    to much family stuff going on.


    ...next thing you'll tell me is your appendix is trying to kill you,  you or something...




    wish you were going to be there, bud.

  2. Wow, Justin - I'm honored that you'd select THAT photo, and even more wish I'd nailed that shot better! Alan, or whoever is going to do the editing for the addition of the flames, if you'd prefer a full size render of that, or even a different format, I've got the original in RAW, so it can be anything and any size you wish, of it will make it easier.



    Great meeting all of you, gang - and great catching up with some old friends, too. Sorry I was so out of sorts, but life has a way...




    Saturday was one of the most humbling and enjoyable days in my memory, ever. Between this and then being approached by Kevin and being asked if I would be willing to put together a demonstration / talk about deconstructing and reconstructing wolf-tooth pattern from historic examples as a potential talk/demo for a future Ashokan seminar I think I spent saturday night and all day sunday with a ginormous smile on my face and a dazed look in my eyes. I certainly dont feel worthy to present at such an auspicious event, but whenever Kevin and Tim want me to do so, I would be honored to bring my whole collection of spear artifacts, dig out the pile of failed experiments and put together a lot of info and a demo.


    I never did post the 20 or so attempts at a historically matching wolfs-tooth that failed utterly or just looked wrong, I think some of them still exist in a pile in the back of my shop. Emilliano was at my shop helping the day I finally got the pattern to match, and in the end it was so simple that it felt like it should have just been obvious.


    I have no photo editing software on my computer Alan, but Matt Gregory just sent me this photo he took of me over the weekend at Ashokan.



  3. Despite my desire to capture great photos of everyone, I fear my head wasn't in the game this weekend, as I got some bad news just before heading to the event. Regardless, here's a few quick shots which weren't horrible:



    Tom Walter and Mike Pulack






    Ric Furrer with his Ulfberht





    Tristan Zukowski and Mike Edelson






    AWESOME Tom Ward photobomb







    Mace and Deker. Knuckle sandwich.



  4. I haven't swung a hammer to make a knife in many, many moons, but I can't stay away from Ashokan any longer. There are just too many folks I've missed for far too long, and recent events have pointed out just how important making time - especially for things like this - is.


    I'm going to do my best to capture the spirit of the event through photographs of the presenters and attendees. It will be great to see old friends, and with any luck, make some new ones.


    See all of you in a few days.

  5. There's been a handful of these kits that have made their way to folks, at this point, and a couple tidbits that were beyond my ability to observe have been pointed out.


    Although I mentioned it in the original announcement post in this thread, it seems to have been overlooked, and this is critical : THE KIT REQUIRES THAT YOU HAVE A 56C FACE MOUNT motor. The motor bolts to the adapter, and without the face mount, it ain't gonna work.


    Also, guys have said that they had to cut the length of some of their tool arms down, as the adapter bracket won't allow a tool arm to stick past it. I didn't notice this on my own grinder, because I added the additional tool arm slot, which lets the tool arms clear the bracket in the top slot, AND I made almost all my own arms and cut them at 18". I couldn't see any advantage to making them any longer, and I could get four tool arms out of a six foot long bar. Things to keep in mind if you decide you want one of these.


    Feedback has been beyond positive. Improved tracking, elimination of vibration, and gobs more torque due to the elimination of belt slip. For most, also, an increase in speed when the VFD output frequency is doubled.


    Figured I ought to pass all this along for people that may want one in the future.

  6. What size gas shock did you buy and where did you get it?


    Josh, most of my mod ideas stemmed from a thread on Bladeforums which David Sharp began on his mods. Not sure if cross-forum posting is allowed, but here's how I guess I'll find out!




    He used a 20 pound strut, I think. Mine is 40. I may, in the future, try a stiffer one, but so far this works great!

  7. One word of note - this kit only bolts to the upright holes where the pulleys were mounted. If you're planning on making your grinder vertical/horizontal, you will likely need to drill and tap another couple holes in this as well as the baseplate for your grinder. I have no intention of doing that mod, so we didn't engineer it into the equation. Shouldn't be a big deal for you to do it, though...

  8. Hi Wayne,

    This bracket is intended for those of us with motors that DON'T have mounting brackets. The only mounting option I've got to mount my motor is C face. Otherwise, I certainly would have just done it the way you're describing. I'm not certain I understand where you feel this mounting system would have any more vibration than using a motor with a foot mount, but I assure you it doesn't.

  9. My KMG has been a source of angst for me since I got it. The pulley system is noisy, causes a shitload of vibration, and tons of power loss. My skinny ass could stall it, and that just shouldn't happen. It tracked poorly, and I spent WAY too much time dialing things in, checking for runout, lining things up... Some things made differences, but it was never right. So, I called in a friend and we looked into what it would take to make it direct drive. The idea was to make this an EASY conversion, should anyone else want to do this. It assumes you have a 56C face mount motor. Mine is 1725RPM, 2hp, with a KBAC-27 vfd which I run in 2x mode (speed doubled). The adapter plate and motor bracket use the existing pillow block mount holes to bolt to the KMG body.

    My machinist friend Joe made this prototype.


    Other than being easy to do, it also means you aren't permanently modifying the grinder, so should you choose to return it to stock, it's simple.

    One of the issues had to do with the length of the factory pulley shaft - it's quite a bit longer than a 56C face motor's output shaft. We could have just had the drive wheel sticking off the shaft a bit, but that's icky. Joe elected to make a custom drive wheel. This one is 5.5" in diameter, with an offset to compensate for the difference in shaft length:



    With everything mounted and ready to roll, you end up with this:



    As you can tell, I've also added an additional tool slot. That sucks up a lot of real estate, so along with moving the drive pulley back AND increasing the drive wheel diameter, you can quickly run out of belt length. My 12" wheel just barely fits. Nonetheless, every one of my attachments works, including my Bader double billy roll, which eats up belt length like there's no tomorrow. The flat platen and contact wheels are a custom rig I made, with a 2" wheel on top and a 3" on bottom. That's one thing my old Wilton got right. Should be a pinch smaller up top (1-1/2" would be dandy), but I had the wheel, so there it is.

    While I'm at it, here's a couple shots of the gas strut tensioner and the monster custom ape-hanger tensioning arm:



    Here's a quick vid of the grinder running wide open with the 12" wheel - previous to this modification, that belt would shift as much as 1/8", and it could NEVER have been run at this speed. The vibration was unbearable. Even the noise is reduced dramatically!

  10. Not sure if this is a faux pas, resurrecting a thread this old or not, but my questions pertain directly to this modification...


    Through a series of truly unique circumstances, I find myself in possession on an almost unused KMG, and I can't tell you how jazzed I am to be able to finally free myself of the infernal Wilton Square Wheel which I've had hanging about my neck like that proverbial sailor's albatross. I need to make a heap of alterations to get it how I want it, including adding a C-face mount to the base plate to use my current motor and vfd setup. Seeing the add-on socket here, this is a huge no-brainer. Thanks for sharing the idea - already have steel on the way to do it!!!


    My question really pertains to your home-made arms, though. Did you just drill a .750" hole and run with it for the tool posts, or did you drill undersize and use a chucking reamer to get the holes truly round? Also, did you just cut the relief slots out with a saw and clean up with files, or did you mill them in? Seems like this isn't too much work to do, especially because I need to acquire a heap tool arms for all the wheels and attachments I've got. Why not make them, right? The material is certainly inexpensive enough, and even if I have to order a couple of purpose-specific bits, it'll be worth it in the long run to invest this way, I'd think.


    Sorry again for resurrecting this, but thanks for any advice you can offer!!

  11. Ai-yai-yai.....

    Somehow for me Jackson's is worse for the total sell-out aspect. Having all the tools at his disposal to do a great job, and coming up with such crap(sorry).

    I thought the second last year might be better but I won't even watch the third.


    Agreed. What Jackson did was heinous, and defiles what may be arguably one of the most important works of fiction of the twentieth century.



    This lil' video is horrible, but it WAS 1966, after all, and LSD was probably more readily accessible then... ; )

  12. We hit Denver, Colorado Springs, Vail, Aspen, Eagle, Avon, Rifle, Mesa, Estes Park, Grand Junction, and a handful of others along the way...


    ; )


    Up here around Buffalo, we have temperature variation from below zero to one hundred on the hottest of days, and intensely humid summers - however, once it gets near a temperature, it tends to stay there for a while. One of the best parts of my area of the world is the wonderfully different seasons. Colorado, however, was a beautiful place to visit. I couldn't handle living in your haunts, though - the heat is the bane of my existence. I could handily live above ten thousand feet, though - give me snow and twenty degrees and I'm thrilled!


    Thanks for all the kind words, gang.

  13. For this year's vacation, my wife and I went to Colorado. Tried to cover the entire state, or as much as we could in seven days. Over one thousand three hundred miles on the rental truck, thirty-five or so miles of hiking at elevation, witnessed a wildfire at night, sleep deprivation, awesome food, got sunburned and frostnipped within twenty-four hours of one another...


    Good times!


    Anyhow, here's some of my favorite shots from the trip:































    Hope you enjoy looking at them, and the shots bring you to a good place, like capturing them did for me!
