Members DieselTech Posted December 6, 2023 Members Report Posted December 6, 2023 Guys & gals I think I have settled on purchasing a Cobra Class 4 Premium package. Is there any optional aftermarket accessories I need to purchase? What do you professionals recommend purchasing for supplies & maintenance care? I'm wanting to purchase everything I might need when I'm ordering. I like to use 207-346 thread when i saddle stitch by hand, so I'm planning on having the machine set up with 277 thread. Should i get some supplies for 138 thread for lighter projects? Also why does most people run a lighter thread on the bobbin side or bottom side of the machine? Is it due to thread capacity on the bobbins? Thanks. Any & all help will be greatly appreciated. Quote

Good needles, good thread, good bobbins and oil. 2 hours ago, DieselTech said: Also why does most people run a lighter thread on the bobbin side or bottom side of the machine? In my opinion, the only validate reasons to use a different size of top thread then whats in the bobbin are: i) Top side thread appearance. Doing this results in the strength of the seam being reduced to that of the smaller sized thread in the bobbin. ii) Using a thread that exceeds the max thread rating of the machine. If you have to use a smaller thread in the bobbin because of bobbin head space clearances you are using the wrong class of machine to do the work. 2 hours ago, DieselTech said: Is it due to thread capacity on the bobbins? No. Yes, you will get more of the smaller size thread on the bobbin but the amount difference is going to be small. Remember these machines are heavy and have a tendency of tipping the nose forward. The head alone is going to be about 120 lbs so getting it placed on the stand and bolts in place really needs at least two people and make sure the wheels are locked / blocked so the stand doesn't move away from you. kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver
Members bladegrinder Posted December 6, 2023 Members Report Posted December 6, 2023 I have the Cowboy 4500 version I bought from Bob at Toledo industrial a while back and I'm loving it. I would recommend the narrow plate for one thing, that's about all I've added to my machine. As for threads, all I've run so far is 277 but Pretty much all I make so far is knife sheaths and holsters. I keep it oiled up good and wipe the feet and needle area before running it. the bobbin holds a lot of thread, no worries there. I don't know if you have experience with sewing machines, I never touched one before I got mine so there was quite a learning curve but I feel comfortable running it now. I just glued up a LOT of scrap leather and got to it. I put 3/4" of glued up leather under this thing and it stitched it right up. Probably the thing I kept messing up most was not double checking the forward-reverse lever position before I got to stitching, but thinking about it now I normally start and finish both in reverse so I don't have a problem there anymore but I make sure to look first anyway! that and turning corners before the bobbin thread was picked up. now I go really slow turning or even use the hand wheel at that point. Speaking of the hand wheel...my machine came with a brake, looks like a Kia brake pad inside the motor, when you step on the pedal it releases the brake, a little more pressure and the motor starts running. I took the brake pad out, it's easy, otherwise you can't turn the hand wheel with out stepping on the pedal. you can do a search here for 441 machines and find a ton of info. I wish I'd have bought mine years ago I hand stitched thick leather for over 30 years, I recently retired, moved to the woods,,built a new shop and decided it was time for a machine. Quote

I appreciate your time & knowledge. Yes I'm going to have a couple friends help with assembly. Who makes the best needles or what brand do you reccomend getting? I'll get extra bobbins as well when ordering. I'm sure I'll forget something & have to place another order. Quote

Thanks for the info. I appreciate your time. So is a narrow throat plate offered for the Cobra Class 4? If so who do I order it from? I have used clothing type sewing machines, but it was years ago. I've been watching some videos on the Cobra Class 4 machine & it seems to be a nice machine, watching the guys using it. Quote
Members Handstitched Posted December 6, 2023 Members Report Posted December 6, 2023 All I ever use on my 441 clone is 277 M10 thread top and bottom, sometimes mixing colours top or bottom and thats it. I use Schmetz #24 180 needles. The less time used changing threads etc. the better. This set up suits my application nicely . So far, I've never had the need to use different thread sizes . 2 hours ago, bladegrinder said: Probably the thing I kept messing up most was not double checking the forward-reverse lever position before I got to stitching, but thinking about it now I normally start and finish both in reverse Yeh same here , When I was learning, I put a large F & R label on the lever in the early days to remind myself where the lever is, lol . All good these days. But, I do keep my fingers well away from the ' business end' .

I personally only use Schmetz needles in any of my machines. I've never had any issues with that brand. kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver
Members DieselTech Posted December 6, 2023 Author Members Report Posted December 6, 2023 Where & who sells a narrow throat plate, feed dog, & presser foot for the Cobra Class 4? I would like to be able to sew thinner materials when the time comes. I would like to be able to sew canvas & soft leathers with the Cobra Class 4. Thanks. Any & all help will be greatly appreciated.

Any & all help will be greatly appreciated. @RockyAussie and @Patrick1 sell narrow feed dogs and plates for the 441 type machines. Patrick also has narrow foot sets for sewing close to edges and raised features. You can message them here or contact through their websites, Wild Harry and Hennigan Precision Engineering, respectively. These accessories are handy for extending the range of the 441 to lighter weight leathers. The narrow dog/plate from Brian (RockyAussie) is my every day set up for sewing tack. It feels more stable to me than the stock plate. The even narrower plates and feet from Patrick are great for sewing next to raised leather features and they do a nice job climbing over increasing thickness, for example the turn at the end of a strap that wraps around hardware. I prefer using #207 thread or smaller with the dog/plate set up that I purchased from Patrick - he has several widths - to have good clearance around the needle. I don't have experience sewing canvas on a 441. That would be a reason to purchase some #138 thread. Quote

What differences or features does these plates & feet have over each other. What's the differences from RockyAussie accessories versus Patrick1 accessories? What does 1 offer over the other? If any? I'm new to machines & trying to figure out what I all need to purchase for the projects that might come up. I'm willing to buy both them guys/manufacturers accessories if both are needed. Thanks for the help. Quote
