Now that is COOL! Pretty clever, you taking the pics while your "willing" helper does the work. Incidentally, I like the anvil stand, that's also .

For a first holster effort that's pretty bloody good. Your ammo, however, isn't .45 Colt, it looks like it's 9mm.

I did that once - a snail was fast in comparison! An interesting experiment but not very practical. Bottom line here is the Kinedyne (Hightex) motor is doubtless a good motor but if I had one, which isn't likely given the cost, I would still fit a speed reducer. And I don't need all the other gimmicks fitted to it.

Yep, pass on it. Old machines like that are a) good for restorers, b) good for collectors or c) could be a useful machine for someone who knows what they're doing - IF the price is right. Which it isn't.

http://hightex-solution.com/blog/technology/2024/0425/315.html?1714026959 This is the Hightex site with info on the 750SH model, which I assume is what we're discussing here. There is a video at the end showing it in operation. It does appear to have reasonable torque at slow speed, but no better than running a cheap servo and speed reducer. For a factory maybe it's an advantage not to have to fit a speed reducer so paying a higher price for a servo may make sense? I said earlier though that for the hobbyist is it cost effective? Not for me, particularly with more than one servo, if a cheapy servo dies I'll simply replace it with another cheapy servo (and save $300+). Interestingly, the link shows a 9-coil motor. Gerry does raise a point about heat generation when running a motor very slow.

Its ONLY advantage over other servos is the claimed startup speed of 50 rpm. Just how practical that is in the real world of leather sewing I don't know. All I do know is that with my limited abilities I need to be able to sew slow and know that there is enough torque to punch through heavy leather - which means a speed reducer.

Mbnaegle has pretty well summed it up. A spray mister is not going to give you much control over the area being "sprayed" or allow any sort of detail work. The external mix airbrushes are the best option for what you want to do, they're simple to use, easy to clean and inexpensive. Where I live they often come up on Marketplace pretty cheap.

Gerry, my understanding is that it's simply a Hightex 750w servo with 12 coils to give it lower startup speed and low-end torque, nothing more (other than a higher price because of the extra coils). I still believe that unless someone goes down the path you have to obtain effective slow-speed control and torque then a speed reducer is needed with a servo used for leatherwork (particularly with the big harness stitchers).

Try dying a piece of the leather before you do anything to it, this will tell you if it's the vinegaroon or something you're doing to the leather (highly likely).

I presume the needle is hitting the needle plate? That will happen if you put sideways pressure on the workpiece, been there done that! You have to guide the piece not force it.

Sure looks a lot nicer than the original!

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".
