I also have removed the NPS from my servo - useless at slow speed (for me). Safe the money and buy a flip down edge guide instead - or thread or needles

Hmmm in reference to your post copied below.  I want a cylinder arm because it seems most convenient. The 227r is only a short arm and I'd like a long arm machine so that I can make computer bags later but right now all I'm doing is a few layers of 5oz leather. Also I like the "Roy Rogers" stitch with Tiger thread for the heavy duty wallets I'm making now. This is the kind of thread shoe cobblers apparently used and almost looks hand made on the Highlead except that the stitching is perfect :) Can the 227r give you that same stitch ?I'd rather go more heavy duty but not if it is going to give me problems when only sewing 1/8 to 2/8 thick leather. Just as a side note I did try the highlead in the store and it worked fantastic during the short time I tried it. Unfortunately I don't think there are any roadshows near Washington state where I can try out different machines to see for myself which Cowboy would work best.

"If you are only sewing up to a quarter inch, or so, the lighter duty, 10" arm CB227R is fully capable of handling your work. This is basically a clone of the Consew 227R machine. It has triple (compound) feed, uses standard walking foot needles and handles #138 thread with ease. A knowledgeable dealer may be able to tweak the clearance of the hook/needle/opener to allow the machine to sew with #207 on top. But, this was not what it was made to sew with."

 

Thanks for the quick response! It is 1 to 3 layers of 4.5 to 5 ounce leather (each layer is that weight). I'm actually lining the wallet with a very thin layer of leather on top of that. Altogether it is about 1/4 inch thick. Right now I'm doing the "Roy Rogers" stitch by hand with Tiger thread and like the look of it so I'm trying to figure out how to do that with a machine.

Sidona to stay inline with your project description the machines really cannot be compared in price completing your capability needs, so being me, hope this helps. The CB4500 compares in work capability with GA2688-1 and this is for a 16" cylinder arm and these are a XHD class machine this also is available in other brands talked about on here as you may know.  If at all considering a short arm version machine then to be fair all other Highlead cylinder machines to my knowledge are all in the thread size 138 and lighter as the GC2268 this has a comparison from several companies, keeping the thread size restrictions in mind as this is most important. I'm trying to keep in mind if thread size wont run in the bobbin I'm not saying it.

To bump the XHD class machines we can change thread colors to tone down the looks if needed but its a serious choice that cannot be changed with smaller thread size in short order.

If leather 1/4 thick sewing 50% of the time then a reducer should be standard purchased item in my op.

have a great day

Thank you everyone for all of your feedback. Just to make sure I'm clear, can a 3500 or 4500 cowboy or the Highlead GC 2268 do 1/4 inch thick and lighter leather (single layer and then up to 3 layers of 4.5-5 ounce leather) regularly or am I better off getting a lighter machine (as some mentioned)? Does anyone know of leather roadshows that take place in washington state where I could try multiple machines out?

These machines "can" sew light weight leathers if you adjust them properly. This means reducing all spring tensions for lighter thread, possibly removing the feed dog and using a flat slotted throat plate (rendering it into a dual feed machine), getting small size needles (not available in leather point below #23) and backing off the top pressure screw.

In my opinion, unless you intend to sew with #207 or thicker thread, the medium duty walking foot machines are a better match for work that is mostly below 1/4 inch thickness. And, if you sew thin leather, the lighter duty parts are less likely to eat it. These machines readily handle #138 bonded thread, which has 22 pounds tensile strength, per stitch.

The 441 clones are designed for very slow sewing of dense and thick leather and cloth, using very large thread (up to #415). They are not built for light duty sewing and need to be dumbed down to do so. If you will be routinely sewing at and above a quarter inch, these machines are your better choice. They can lay a line of #277 thread inside the layers, which has 44 pounds strength per stitch.
