If you are on that side of the pond, lucky you, Abbey England is nearby. Lots of hand sewing thread to be had from them, decent prices too. YinTx

Outstanding work! Impeccable tiny tooling. Welcome to the forum, look forward to seeing more of your work! YinTx

I'm beginning to think this is the best option. And that drawer is just there to cause jambs. And to make the mfr's feel like they did something to catch the leather for you. There just simply doesn't seem to be much out there, so anything that helps clear the mud or adds another way to do things can only help. I've seen one or two of your videos and had no problem understanding what you say, so just be fearless, yah? I haven't had time to mess with the thing this week, but have been trying to keep up with the info posted here, so thanks much to everyone participating, great info showing up so far! YinTx

Welcome! And be sure to share some of your works here, show it off or put it in the critique my work section, you are sure to get a lot of constructive feedback. YinTx

@jimi those are some fantastic photos. Some similarities and differences, at least I can see how the thing might be put together. Thanks for the links, definitely helpful. Took the video with an old Samsung SIII phone, and have a MacBook... barely compatible with each other lol. I'll fart around this week and see if I can get some of the videos I took today to upload... Yep, I have two of them already, don't want a third. Hoping I can get the other two functional with some simple parts, like a bushing, but the suppliers won't quote me a part. Going to have to have them made it looks like. The world we live in. YinTx

I'll do what I can, but in past I have not had luck uploading videos. Takes hours, and u-tube says too much data for a 3 minute video. I am not sure how folks upload 1.5 hours of 1080p video - they know something I don't! Better photos than I will get are above! Seems like this thread may be helping more folks than just myself.. Thank you all that are providing assistance! Yep, the 6 pager. Purty lame. yeah, I think I saw that video. Had the bell set way back too if I recall. I kinda trusted other videos more, didn't really follow anything from that one. You do. Lots of experience speaks volumes. I'm trying to listen and learn here.

Ed the "BearMan," thank you for gracing us with your presence and works again. I always enjoy studying your tooling to see where I can improve mine. It will take many many years of practice to get anywhere near your level. Just phenomenal. YinTx

I had seen this video, and pretty much followed it. Thanks for posting it, others may find it useful. I didn't have the issue he had with skipped sections, but the angle of the grind was off due to the bell being so far back initially. Mr. Bane was freaking me out feeding that leather through one handed with his fingers right above the bell business end. If that had bit into the leather there, he would have had red accents on the black. I keep my fingers clear of that thing at all costs. YinTx

yeah, I would have engineered it that way too. I know a company that makes metal wire scrapers, I may replace it with one. This one is frustrating. It pulls the pieces in right away as they are getting cut. Defeats the purpose a bit, I'd think. Probably better than trapping leather trimmings! But I'll try to get a photo later this week if I can. Kinda hard to get the phone up in there and all... I think so. I imagine it has a lot to do with the fact that the spinning bell lifts the leather towards the operator and thus the scraper, causing it to fall down. It seems to do it's job ok, the other scraper tho leaves a lot to be desired. I'll look closer, when I was looking at it last night I noted it was on a spring, but didn't seem to actually touch the stone. Perhaps it is somewhere that I can't really see, like the backside, closer to the operator. I don't hear any rubbing or anything while in operation tho...I'm just glad I am willing and able to troubleshoot this thing. Otherwise I'd be one unhappy camper! YinTx

Thanks @RockyAussie for more pointers, I've bookmarked the goods. However, perhaps the plot thickens. Here is what I came across this evening. I noted that the feedroller was constantly pulling up leather fuzz and feeding it to the bell, as I was running it with no leather. So I peered up underneath, and lo, jammed up under the feedroller was this nice little ball of skived leather. I worked it out, and it promptly trapped another. I am assuming this is not normal behavior. How do I remedy it? Do I need to just scrap this scraper? Entirely possible, I've tried to make sure there isn't one, but this bell thing is new to me and I'm learnin... I also have proof the good leather sensor is functional on this unit. Ran a lot of scrap in there, it skived beautifully, went to skive the good stuff, and viola, shredded. Picked up a piece of scrap without changing a thing, skived it perfectly. Sensor functioning. YinTx

I have no idea, but the back is inked "Horween" it was sold to me as Essex, and it rubs off everywhere. I did a small sample strip with Tankote, and the cotton pad with the Tankote turned black too. YinTx

I have a side of black Horween Essex leather that I am working with, and I am finding that it is leaving black dye on my hands and such as I work with it. I am concerned it will transfer to clothes etc. if I use it for a customer. Anyone have this issue, and how do you remedy it? Will TanKote do the trick, or will it just streak and make the leather look plasticky? YinTx

Pretty cool. What does the back look like? YinTx

I've seen a lot of round hole stitching going around, and wondered how well the patterns would look with standard chisel stitching. I must say you did it justice! Fantastic look. YinTx

Awesome! I've tried three of these things and have failed each time, so kudos! YinTx

Yes, there is a scrap ejector. The plugging was clearly operator error, the jicky little bin under it was full and that stuff had no where to go but up. I removed the bin and let er fall to the floor. The ejector has a better chance of doing it's job for now... The first day I had it, the bell was about 1/2" back from the presser foot, and when I moved it forward, the stone beveled an angle that was no where near the cutting edge, so it had to get re-profiled. I tried to follow up with a really light touch, but it has always had that pattern on the bevel. I thought maybe that was the way it should be since I've never seen one up close until this one. I felt it was a bit harsh myself, but kinda didn't know for sure. Even the light touch with the stone leaves these marks. Do I need to find a different stone? It seems to grab on to whatever leather I am using like glue right away. I'll get a brass brush and see if it'll clean up.. but if it keeps up past performance, it'll get gummed up fast. Do I need to replace it with something that won't? my hunches confirmed again. I think this thing can be spun around for a less pointed approach, I'll give it a try. I'll give this a whirl. I can't wait to get this thing dialed in and my skill up on it, I think it'll open a whole new world for me... YinTx

I've noted that as well. In the case of the photo, it was all jammed up in there. Yep, vacuum excavator is next in the works I suppose. I had no idea. And I don't really know which one is set with more tension that which, so next time I get back to it I'll check for sure. I'll have to print out these tips and put them with the machine until I get em all memorized! YinTx

Spent some time with it last night, shredded a box of crappy leather until it was running smooth. Put in a nice piece of leather and the "good leather" sensor activated, allowing it to cut too deep right away. Gah. anyhow, 90% improvement in my success using the machine. I took a look around without making any adjustments, and noted that the bell was jammed up with leather bits. I cleared it out, removed the jicky catch bin, and allowed the leather bits to fall unceremoniously on my feet as I worked. Per @RockyAussie's comment regarding clearing the machine of leather cuttings. I think this had the single most impactful result improving my outcomes. View of leather build up: I also ran a sharpie again, and just touched the wheel to the stone. It evenly removed the marker as shown, so unless someone thinks this is not what I should be seeing, I imagine it is not the issue... sharpie... Post sharpie and stone: Clearance Settings views: Thanks for all the help and tips so far. Please let me know if there is another view that would assist in troubleshooting how I have things set up or how I am using the machine. YinTx

This is what I used to set it up originally, as it was all out of whack. I'll go through your other tips to see if I can get any improvements also, thank you for those. Presser feet look shiny, but I don't have anything to reference. Was looking for a roller foot earlier, hoping that would help things a bit...used a sharpie to run the bevel just before these photos were taken, and used the rod stone to lose the burr on the inside at the end of the run. Seemed ok... More leather shredding in my future this evening I think... YinTx Meant to mention the truth behind this. It is clear my sewing machines both have one. scrap runs fine, and the real deal skips stitches, pulls up knots, runs crooked lines, etc. YinTx

@Starwind0 I thought it was a Chinese made knife? Anyhow, it took an edge really well, I have been using it just fine, so if it doesn't sell, no problem, I'll keep using it. Thankfully, I don't have 100 of them! Just this one. The hand stitched sleeve I made for it might be worth as much as the knife lol. The second is sold, definitely a nicer knife. YinTx

So, I have a new (to me) Cobra NP-4 skiving machine. Been skiving up miles of leather, followed proper (as far as I know) settings and sharpening procedures, but it seems I am still doing something wrong or I have something set up incorrectly. I am skiving some black 5 oz Horween Essex leather. It seems to go fine when I am dialing things in on scrap bits, then when I put iny s the leather that matters, I screw it up. Any pointers would be greatly appreciated! Not sure if you can tell from the photos, but it will skive just fine, then all of a sudden dig in and skive to the thickness of a plastic bag, if not punch a hole all the way through. And this without changing any settings. You can see at the top, bad skiving - super thin, and cut through. On the right, a decent 0.9mm skive. Here is a closeup of the bad skive: And finally, good skive on the bottom progressing to bad, then wreck my leather skive on the top.

If you are referring to mine, yes, I believe it was a backgrounder. YinTx

Fantastic! sadly mine is still in cogitation phase... Yours is inspiring! YinTx

Nicely done. The coaster I did for the swap, I used the bear template from the Wildlife set as well. It was a bear for me. I had a difficult time with the shaggy fur on the backs of the legs. And the eye is deceptively difficult. YinTx

Interesting design. Can you show it with some cards and cash? I'm curious how it all comes together. YinTx
