Members kyleatherworker Posted October 15, 2018 Members Report Posted October 15, 2018 Hello, I just bought myself a very nice Cowboy 3200. Man, do I love this machine. Such a difference after working on a Tippman Boss. However, I'm experiencing some issues in regards to the feed foot and presser foot impressions. The samples that came from Cowboy didn't really show this. But, I did swap the double foot for the left walking foot right away. The attached photo shows the impressions being made, specifically with the main walking foot inside the radius at the bottom of the trigger guard area. NOTE: this appears worse than it really is due to the glare. But, it's still worse than I'd like. I've loosened the top pressure knob for the walking foot. Again, I can live with the impression it is giving. But, I'm uncertain what do on the main walking foot. The instructions state about how to raise or lower the main walking foot. My question....will this correct this? If so, what is the consequences of this when going to lighter material? The holster is Herman Oak 7-8oz. 2 pcs. I want to also to sew 3 layers of 3-4oz. (so, about 1/2). BTW, I sewed some pocket knife sheaths from two layers of 5-6oz. and didn't really notice this as much. Thanks for any and all help! Quote
Members SolarLeatherMachines Posted October 15, 2018 Members Report Posted October 15, 2018 top of the machine, left hand side, theres a large black screw that adjusts the foot pressure. If you are pre-glueing the holster together, then you can unscrew that large screw and reduce the foot pressure QUITE a bit. NOTE: when you take the double toe off, and replace it with the single toe, the pressure on the single toe is DOUBLED to resist the spring. Quote Alexander
Members kyleatherworker Posted October 15, 2018 Author Members Report Posted October 15, 2018 Thanks for the reply. I was wondering if the force was increased on the single toe. Any thoughts on whether raising the foot higher will also reduce the amount of force? Of course, will this also lesson the pressure to the point of slippage? Quote
Moderator Wizcrafts Posted October 15, 2018 Moderator Report Posted October 15, 2018 Back off the foot pressure screw on top until the leather just begins to lift with the ascending needle, then add some pressure to keep the leather down. If that doesn't fix the problem, let the leather fully dry before you sew it. You can also lower the lift of the feet via the crank arm protruding out the back of the machine and fitting to a curved slot on the lift mechanism. One direction lowers the lift and the other increases it.

Members kyleatherworker Posted October 16, 2018 Author Members Report Posted October 16, 2018 Thanks Wiz. You know, the weather has changed here with some colder temps and rain. And, although I did let the finish dry for 16 hours, it might have needed a tad bit longer. This may be reason the samples pieces that came with the machine didn't show as much. I just didn't think about this. Time to do a better test now. Thanks! Quote

Build a "dry box" Just a basic wood box with a 100w lightbulb in it. The bulb will quickly heat the box to a very warm, dry temp, and greatly increase your drying speed. Quote Alexander
Members kyleatherworker Posted October 18, 2018 Author Members Report Posted October 18, 2018 Hi Alexander, Thanks for the suggestion. I may need to do this. I've done more testing on the 3200 with lighter weights leather (2-5/6oz. & 2-3/4oz.) both were in regular dry form from the supplier. All harness leather and natural Herman Oak. In both cases, the walking and presser foot are still leaving more than desired impressions. I've adjusted the presser foot tension until the adjustment knob jumped out. Luckily, I was anticipating this. So, I think I may try a small adjustment on the foot height linkage arm. But, will this move both the walking foot and the presser up or down with the single adjustment? Craig Quote
Contributing Member JLSleather Posted October 18, 2018 Contributing Member Report Posted October 18, 2018 Where's the picture of the marks on dry leather? If your machine is making the marks in your picture on dry leather, I would assume your machine has the WRONG SPRING. Quote "Observation is 9/10 of the law."

Members kyleatherworker Posted October 19, 2018 Author Members Report Posted October 19, 2018 Here's a few pics showing two layers of 7-8oz from belt blanks. And, two layers of 3-4oz. Both leathers are dry and untouched. Don't mind the thread/needle size on the 7-8oz. I didn't bother changing it from working on wallets. Also, check out the backside. It's pushing hard enough to leave a reverse impressing from the cylinder arm plate You can see the walking foot impressions are deeper than the presser foot. The presser foot adjustment is as loose as it will go. So, will adjusting the foot arm on the back of the machine move the entire foot assemble up, including the presser foot? Quote
Members dikman Posted October 19, 2018 Members Report Posted October 19, 2018 Best thing to do is try it. If it doesn't work just move it back. Quote Machines wot I have - Singer 51W59; Singer 331K4; Seiko STH-8BLD; Pfaff 335; CB4500. Chinese shoe patcher; Singer 201K (old hand crank)
Members chrisash Posted October 19, 2018 Members Report Posted October 19, 2018 Make a mark on anything you want to move so you know where you started maybe a sharpie or scratch, saves hours of geting lost and screwing up everything rather than just one thing Quote Mi omputer is ot ood at speeling , it's not me

No,it won't because you'll still have the same amount of pressure.Your marking with this type of leather would be less with a lighter pressure foot spring.I also know a lot of people just rub the marks out w/a spoon or bone.

DonInReno Posted October 20, 2018 Report Posted October 20, 2018 Roughly I’m guessing a lighter spring is less than $10? Quote
