The Cowboy CB4500,3500 and 3200 narrow needle plate and feed dog set. Why was it developed? A few years back I decided that I wanted a cylinder machine that could handle a wide range of threads (particularly thick) with a large bobbin that could hold a lot. Smaller machines I have could do thread up to 138 (20m) but with that size thread in the bobbin I may only get 1 or 2 belts done before the bobbin needed loading again. Also the thickness of the job would often be more than desirable for the machine to handle. I managed to get a Cowboy CB4500 from our local dealer at the time and found the machine could do large jobs like tool pouches and such with no trouble but..........when I thought I could do smaller weight projects like wallets I was sadly mistaken. The large needle plate hole and wide feed dog allowed the job to be pushed down into the hole if I wanted to get closer to the edge than about 5mm and it would make a mess of any edging that was done prior to be stitched. I was approached by the local correctional centre about this time to make up for them an improved stronger personal alarm pouch and the numbers were pretty significant. I went ahead and designed a good pattern and proceeded to put it into production. Here is a picture of the finished article – Everything went well up until the stitching stage. The best way to do the job was to get all of the edging done first before the stitching and that is what I did. I knew when I was doing it that the job was going up and down a lot and was very difficult to control but I did not take enough notice of the edging at the time.. This picture below was by no means the worst one but just an average one after the stitching. “Golly” I said (perhaps something stronger and shorter to be honest) This was going to take a lotta fixin On a close inspection I found the reason. This belt strip shows that at the start of the strip as the needle enters the job all looks good. Then as the needle goes back with the dog foot and the dog foot descends the belt strip lowers down into the hole as well. The sharp edge of the needle plate was tearing up the edging every time the dog foot went down as it got to the back of the hole. This set me onto a path to find some way to get this machine to behave the way I wanted. After a year or more later and a good deal of development time with the new Cowboy sewing machine dealers here in Australia (Good people) this is what we came up with. A narrow needle plate which has a narrower hole in it than the original and also been reshaped to improve tighter curve stitching like gussets. The narrow feed dog gives the advantage of assisting the needle to be guided at all times through its motion whilst the feet are down. This means the stitches are less likely to miss and revering is now more accurate at lining up the stitches. Previously a narrow slotted needle plate was provided but that involved having to take out the dog foot altogether and at the cost of an unreliable stitch length at times, especially in reverse. This shows the original needle plate hole width in metric (8.75mm) and the next in English (.344 of an inch) This next picture shows the new needle plate hole in metric (5.54mm) and following that the English size (.218 of an inch) Due to file size limits on loading here I will follow this up a bit later with a link to a couple of video's I have done showing off the improved capability given with this new set as well as some practical use pictures I have taken whilst making some of our products.

I have a like new cowboy cb-3500 it's only been used a handful of times I bought it from Bob at Toledo early this year. I've found that this is more machine than I need and prefer to hand stitch. It comes with everything you see. 1#white 277 1#brown 277 1# ea white brown black 207 1# ea white brown black 138 8oz red 207 8oz red 138 2 packs schmetz sz 23 needles And a half a pack of sz 25 Can meet within 50 miles of 41046 inkdbulldog@gmail.com 8593608990 Can send pics upon request 2000$ obo

My issue I need help with: I keep seeing the bottom thread pull to the top. basically flush with the top surface. Equipment specs: CB3200 Thread - 138 & 207 (I explain why the two) Needle 19/120 or 23/160 Leather thickness: I'm needing to use on oil tanned leather that at a minimum is about 7oz. thick. I've tried tightening the bobbin tension to almost the max and have loosened the top to see if the bottom will help pull it down further. The two needle sizes and thread sizes are what I'm having issues with since I'm trying to sew thinner leather. The 277 thread and 25/200 needle which corresponds to the thicker leather my machine can do is no problem. Is what I'm trying to sew just too thin for this machine? I notice on 10-18oz thick it does fine and pulls center within the leather. Thanks in advance

Below is my latest creation made with exceptional bling from RaySouth and the outstanding stitching of my CB3500 from none other than CowboyBob! Thanks much, gentlemen, for your guidance and superior merchandise.
