Sounds like you're chickening out from trying it?

You did good!!! Opportunities like this don't come along too often. (P.s., I'm jealous).

I wonder where they got these things from in the olde days when they supposedly used chicken fat?

Excellent job. I particularly like the way you ended the pattern by extending it to the end of the belt, most just stop it at one of the "crosspoints".

Good luck on doing that!

Yep, me too. I got all excited about all the features on my new wiz-bang first servo and Wiz's comments on analog/brush servos with only a speed control knob had me thinking he needs to move with the times. It's only as I've gained more experience that I've realiised he was right all along. If I could get hold of one of those it would be no big deal to modify it to move the knob away from the motor and near the head unit. That would be an ideal setup. Meanwhile I'll stick with my el-cheapo servos and home-made speed reducers as the Kinedyne motor is not going to do anything better, in fact I suspect my setup is better for my needs as I will get more low-end torque with the reducer. Plus it gives me the ability to tweak the operation by changing the pulley sizes to give me even slower speeds with even more torque if needed.

Nice blogs regarding cutting/punching boards Bruce. Regarding glass, I have the top off a pair of bathroom scales, it's toughened glass and very smooth but only about 15" square. Still very handy for all sorts of things.

I was going to say nice and simple - until I saw the back! Nice job.

That was my point Gerry, I don't think the OP understood what he was agreeing to so no, no gearbox. A bit more searching confirms that Kinedyne is a brand of Hightex, so these are merely Hightex 12-coil servos, not something radically different and super-special. This merely confirms that it's a publicity exercise as anyone who thinks a company like Hightex is going to take notice of discussions about their motors on a forum and make changes to suit their wants is kidding themselves. The OP said it himself (herself?) they are made for the wider commercial market.

Rather than start a new thread I've tacked this on here. My daughter has a gym and some time ago when she moved locations she had a heap of rubber mats, the ones they use on the floor of gyms, left over so I grabbed a couple (I didn't have a use for them but....). Anyhow I've been using them to stand on in my shed when it suddenly occurred to me maybe they would be good as a punching mat? They're very dense rubber, so very heavy, and 15mm thick (3/4" for any heathens out there). Tried punching some leather, nope, just lots of rebound! Hmmm, a cutting mat maybe? Yep, that seems to work, has some "give" so hopefully won't blunt knives too easily and the leather doesn't slip on it. I guess time will tell.

Al, I understand what you're saying, I've spent $1000's since getting into shooting (primers and powder are ridiculously expensive now ) and once I got interested in leatherworking I sort of lost track of the expenditure BUT I also do my homework and there's nothing I've read to indicate replacing my existing motor/reducer setup with this "supermotor" is economically viable, nor do I think it will do anything better. Goods in Australia are more expensive than in the US so unfortunately I tend to get "wrapped up" in pricing (particularly since that Chinese Cough has stuffed up shipping costs!). I'm just genuinely confused about this motor and this thread, I think Cumberland Highpower probably picked it, the motor is already made, with the features in the first post, and this is essentially a publicity blitz.

A google search for Kinedyne was interesting, the company specialises in manufacturing cargo handling/securing products. They do not make motors they source them from Hightex, who I believe manufacture Cowboy sewing machines. So, who is Cowboy Outlaw working for? The posting makes it sound like Kinedyne, but that can't be the case because they don't manufacture motors but the OP is talking about seeking information for the next motor they're making. If it's Hightex then I doubt they would be very interested in what we say because by his own admission they make motors for large manufacturers who want features we don't. And you didn't answer my question - does it have a built-in gearbox, which you said it does in reply to GerryR? This is becoming confusing.

So your motor has an internal 5:1 gear reducer? That's what you just said, and if so that would explain the high cost. You say that an NPS is "necessary". Who says it's necessary, it's the considered opinion of some of the more experienced on this forum that it is not necessary. I think we need to clarify exactly what your intended market is, on the one hand you're emphasizing extreme slow speed control (without needing a speed reducer) for the likes of a 441-class machine and then you're talking about the necessity for NPS, jog dials, needle up/down position and 1/2 stitch adjustment (?). For a decent servo to run a 441 sewing heavy leather you only need to keep it simple, as has been pointed out - slow speed and easily adjusted variable speed, nothing more is needed. All the other "extras" are more suited to higher speed sewing.

That's commendable that you make your own motor, although if you had so much trouble with the original motors you supplied why not just change supplier? It would be interesting to know the failure rate of the motors used by other sellers - Cowboy, Techsew etc. In general modern electronics are pretty reliable but ANY circuit board can fail at ANY time, often for no discernible reason, although surges/spikes are often the main culprit. Wiz, interesting thought but I'd be surprised if they use optical sensors, everyone seems to have gone to Hall Effect sensors now.

Just did some checking, your current servo is available here (Australia) for Au$500 plus shipping, generic servos start at Au$ 140 shipped. Bit of a no-brainer really, even at $200 it leaves me a lot of money for other things.
