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.

Mmmm, ok, this is primarily a hobbyist forum and our needs/wants will be different to those of a large manufacturer of leather goods. WE want controllable slow speed and torque out of a servo but to a manufacturer slow speed = lost time so I doubt they would be interested. Your potential market is harness makers, saddlers and those who make goods using heavy leather but it is not exactly a huge market, in fact I would say it's a very specialised market, with probably very limited sales possibilities. The obvious market is to convince those Chinese manufacturers of leather stitching machines to use your motors with their machines but that's probably unlikely as they will be dictated by cost and the cheaper generic motors work well enough for them. You're not appealing to the hobby market as your motors are in the upper price bracket, so I'm not sure where that leaves you. To get back to your original post, so far it's not looking good for your "options", other than a good variable speed control. If your Swedish/Italian people need them then it shows that their needs are different to ours as hobbyists. So who are you going to cater for?

If you consider Ho Hsing and Efka as your competitors then you've come to the wrong place to promote your servo as very few on here buy those motors (other than as used units that come with a second-hand machine). You can't compete with what most of us buy, generic Made-in-China servos off ebay (or from a dealer, selling those same generic servos). You're response came in while I was typing, you're missing my point, I can buy a generic servo and a speed reducer for less than your motor and it will achieve the same results. For me it's even cheaper because I make my own speed reducers. At one point I had a machine that could do one stitch every 3 seconds, it's not that difficult to achieve.

When I bought my first servo I was fascinated by all the settings in the menus, over time I realised that for the most part they were irrelevant as once I had it running to suit me I didn't need to change anything again. Like KGG once I have it set to an optimum speed (for my needs), including a speed reducer as the generic servos need one, then I don't need to change anything. Your Kinedyne is apparently a superior servo compared to the array of generic servos available but the price reflects that and while I would love one as a hobbyist spending that sort of money isn't justified when the cheaper option is working fine. Plus I have more than one machine! I'm not sure which part of the market you're aiming for, the vast majority on here are hobbyists and like me can't justify the expenditure for a Kinedyne so you're unlikely to achieve much in the way of sales and if you're aiming for the commercial market you've come to the wrong place.

I guess it depends what market the OP is aiming for. I think it's fair to say that most don't want fancy options that they will never use, once one is set up for leather sewing it's doubtful they will fiddle around with the options in most servos - other than speed control. Yes, I know some like an NPS but once you have your machine setup for sewing leather, which generally means slow-speed, then an NPS isn't necessary. Having fiddled around with several different generic servos/speed reducers my optimum for sewing leather would be very low speed startup, lots of torque and variable speed using a knob placed near the machine. Having converted my lathe to a VFD I can use a knob to vary the speed at will, it is a much better system that anything else. And make it affordable!!!!! The OP has a "high-torque" motor currently available and it is apparently pretty good but at 2-3 times the price of generic servos I won't be buying one.

As Sark9 said because it's a treadle machine there's no easy way to fit a foot pedal to lift the foot. Adapting a knee lifter is the only practical option that I can see.

A couple more photos would be nice but it does look very well done.

Whilst I do have the actual ammunition for what I've made so far I made up a set of dummy rounds in .38, .44-40 and 12ga, makes it much easier to make belt loops. I also have an assortment of empty rifle calibre cases if I ever need them. I'm guessing you couldn't have them either?

I've had that happen (hook piercing the thread) with a spool of braided thread that I have. In general my machines don't like it and I can't get them to sew consistently, which is a pity as it's nice thread otherwise. It's a very "limp" thread which is the problem I think. Adjusting the hook too close the the scarf in the needle can be risky as it only takes the slightest deflection of the needle to cause a crash.

One of the joys of buying old(er) machines, you never know what may have been changed. Calidora, looks like you've got it sorted and could be a handy machine to have.

Once you mentioned holsters that immediately puts you into the heavy sewing machine category i.e. the 441 class. Trying with anything less will be a failure, don't even think about it.

Lots of youtube videos to watch and learn more about leatherwork.

Indeed! If you join a car or motorbike forum I can guarantee there will be a thread titled "what is the best oil to use?" and there will be endless discussion/argument about the subject.
