    Re: sharpening

    I measured the motor pulley and it is 6 inches in diameter. That puts its circumfrunce at just over 18 inches. At 1725 RPM, the belt travels approximately 2700 feet per minute. That's about 30 miles per hour.
    It is certainly manageable but I'm glad its not any faster.
    Has anyone tried using an electronic speed control on something like this? I'm sure it would reduce the torque but that wouldn't be a problem.

    Re: sharpening

    I think my earlier post wasn't clear. The Ultimate Sharpener (Dennis Moor's unit from Chipping Away) does NOT run at 3400 rpm. It runs at 1725 rpm. I'll calculate the FPM and let you know since that is more relevant.
    The machine that I referred to that does run at 3400 rpm is a home built motor/wheel unit made by an individual to suit his personal preference.
    I'm sorry if I confused anyone. I like my Ultimate Sharpener and wouldn't want to mislead anyone.

    I would have the same reservations as Kenny on the 3400 rpm speed of a grinding wheel. Would probably be ok for smoothing a weld on a 10' steel girder but not on my carving tools.

    Re: sharpening

    Isn't 3400 RPM a little fast for sharpining or stropping a knife or tools. I would think a lower RPM would be best on the tool and the Carver. May ne wrong on this but at 3400 RPMs, one would have to be awlfull carefull in not burning the blade.
    Gues one could step it down in RPMs by rewiring it or adding a bigger wheel(pullies).
    I am not talking the product down just questioning the higher RPMs.

    Re: sharpening

    Hello there, sorry for the intrusion. I was looking for a woodcarvers forum for my brother-in-law ,when I seen this discussion on sharpeners.
    Earlier in this discussion there was mention of a 2 roller sharpener. I have one ,and love it . It is known as a knife belt grinder. It is widely used for grinding out knife blades. Mine is a Grizzly brand and works upright or pivots to horizontal . It has a 72'' x 2'' belt. There are also 48'' belt grinders out there. A search on a search engine for knife grinders should bring results. Grizzly Tools is located in Springfield MO and has a neat feature. If someone in your area has purchaced a tool you are interested in and gives permission they will tell you who has it . I drove a short ways to see a grinder and liked it and met a nice fella in the process. Good luck, I'll recomend my brother-in-law take a look at your site. He has carved for many years. Mike

    Not sure if this is what you're talking about, but...Roger S. reviewed the Koch sharpening system for the next issue of WCI. It's a thermal reactive paste system that promises not to burn your knife or leave a burr...Roger rated it very highly!!

    Re: sharpening

    Al & Dave -- you know you're talking to a mechanical dummy (a dummy mechanic ?). I have a Delta 1' vertical sander and Longo's sharpener is nothing at all like it. My Delta's belt runs on a 3-point circuit (is that the right description?) and it runs the wrong direction for sharpening and it's 'way too fast.
    Longo's has a Ba???? motor that runs the reverse direction at 1100 rpm (I think) and it has a 2-point turn instead of 3.
    Did I make ANY sense at all? I gotta' get some photos. :-[

    Re: sharpening

    My bandsaw has a platen that I can attach and use 1/2' sanding belts on, but it turns the wrong way for any serious sharpening. Pretty useless piece of equipment, actually.

    Re: sharpening

    nancy. that sharpener/sander you are describing sounds like my Delta 1 inch vertical belt sander and it has a 6 inch disc sander on the side....I believe you can get leather belts for it too.

    Re: sharpening

    Looking forward to your visit Al !!
    I wish everyone could see the machine Al Longo has -- it looks like a vertical belt sander and the belt is backed up by a piece of metal so you have a firm, flat surface. The metal is just half-way up the belt so there is a 'soft' area if that's needed.
    And it has leather belts, all sorts of sanding belts but they're not 'normal' sand paper .... they're micro-fine. Maybe I can get him to send me some photos.
    I'm mighty tempted to buy one -- but it too requires that light touch that I seem to lack. Maybe I'M the metal melting monster and it's not the Stephan.
    Anyhow Al - hurry on down .... I have the coffee on and the cats have some things they want to talk to you about.

    Re: sharpening

    I could have used something Saturday! Spent 'the day' sharpening a set of 12 new tools, 'Henry Taylor' set of relief carving micro tools. Finished at 11:30 at night.

    Though factory sharpened and ready for final honeing, most had to be re-shaped, and some serious time was necessary on some tools. Two are being a pain in the ***, still not happy with the results, but the rest are a dream to use. Love the new shaped handles, fit right into your palm and with the bottoms flat, they allow you to get really nice and close to your surface.

    Water Stones may not be fast, but what an edge they will put on! You just need patience.

    They did allow me to finish a relief carving that has been awaiting their attention for months, and I'm happy with the results.
