That it is. I have never come across any other machine that can sew that close to the edge of a product. Only problem I have with it is that the needle goes in the other direction (long slot to the right) and so does the thread. Cant think how many times out of habit I have put the thread in from the left instead of the right. Makes stitching tall totes an easy job when you get it right though. . I have done a bit of a crappy video (more crappy that my usual stuff) on a tote bag stitch which I will put up soon only because there is so little to be seen out there on these machines in use.

Is that fob attached to the belt keeper? How is this so done? That to me is artistic

The machine for that job is a tall post. This is a couple of pictures of one I have here. It is a Cowboy CB 8365. I have not had time to do any videos yet but I will try and get some up soon.

Good Video @TomE and thanks for sharing. You may think about using a temperature controlled soldering iron as I have used for many years now. Here is a post I did showing how I made one up using a light dimmer switch Although I have used edge coat in that posting it does work well with wax coatings as well.

May be able to help. If you want send me a pm message with your phone number and I will give you a call or swap back my ph number.

Had me looking for a bit but I think this is the one you mention Matt

One on the left I am pretty sure is a sole stitch channeler. If it is the same as one of mine somewhere it has a curved blade that cuts an angled slice just in from the edge of the sole which gets pushed back when stitching the sole on and then gets glued down to hide and protect the stitch.

New Sewing Machine GA441 Sewing Machine
RockyAussie replied to Tim Schroeder's topic in Leather Sewing Machines
As long as Pats needle plate can move a little to the left when done up then you can adjust the feed dog as I show in this video - You could also file away some on the left inner edge of the needle plate if needed. -
@robygen There are a LOT of possible reasons that could cause this and to help narrow this down it would help to have some pictures or even better a video showing what is happening. Have you used the machine alright previously or not? Do you have both feet attached? When you say the presser foot does not move do you mean they will not lift? or will not move forward and back?

Could you load some pics of the thread path showing the top tension discs and down on the bottom around the thread return spring? The thread return spring may be getting too much travel but the spring pressure of it may be applying too much pressure as well. It can be adjusted to give more or less if needed. The thick thread you are using may be going through too many unnecessary paths as well. Pictures will help. Did you back out the bobbin race cover screws as Wiz suggested? Some newer machines can be a little too tight in this area and may need some sanding back to allow the race to move freely as it should in there. Ideally when the screws are out about 1 turn you can easily move the race in and out and the springs will keep things in place. In your videos the screws appear to be wound in tight.

Presser foot for cowboy harness machines
RockyAussie replied to milkman's topic in Leather Sewing Machines

As Wiz said above there is a possibility that the feed dog could be loose or needs some sideways adjustment. This video I made although done for mounting the narrow needle plate set would hold true for the standard set as well -

Presser foot for cowboy harness machines
RockyAussie replied to milkman's topic in Leather Sewing Machines
That setup will be fine for doing the bag gussets though you may want to get an open toe center foot for better vision. We make a narrow needle plate set for the cb3200 if that helps and you can read some stuff about it in this post if you like If you would like a set pm me here and I will get back with a price delivered. I would need to know what country you are are in to work out the postage cost part. -
There are a whole lot of varying factors that may need to be considered such as the thread take up spring pressure etc but ...to simplify this tension question, if the leather is thin or soft you would normally run light spring pressure on both the top and bottom tensions. If the tension is too tight it will gather the leather together. If you were doing firm leather then you would run a tighter pressure top and bottom. As a very rough guide on most machines you would start off by having your top tension adjustment so that the the screw adjustment was close to half way in. If you had say 9 full turns of adjustment untill you could screw in the top tension no tighter then the starting point ideally would be about 4 and 1/2 turns out. This then means that you have the most adjustment possible tighter or looser on the top tension. Once that is set you then set your bobbin tension so that it can be pulled out by hand reasonably easily to start with then test stitch and adjust until the bobbin spring pressure balances the knot consistently. This should give you a setting that for most leather only requires adjusting the top tension. The top tension is then way easier to adjust on the run if needed which is something I do when the thickness or stiffness changes on jobs as it does sometimes. Foot pressure is also important to adjust on the run sometimes etc. In this video I start with some fabric and the tension is tighter than it should be but not shown is where I tighten the top tension several times as I go up into the thicker stiff leather -

Help with machines, leather and rubber sole.
RockyAussie replied to Kovant's topic in How Do I Do That?
Rubber soles need fairly rough sandpaper to cut away well and that means the grinders you show above lack the horsepower to do the job. A 1 horsepower would be a better choice. The https://www.justwood.com/buy/75mm-sleeveless-drum-sander_34.htm link is reasonably useful up to a point and I have used it for sanding edges of leather when making belts etc. This link shows a video where I have used a couple of 1/3hp motors and similar sanding drums to sand belt edges if that helps - What rpm is ideal will depend on the diameter of the sanding drum as the surface contact area is what is what counts. The smaller the drum the slower the contact speed. On a 6" drum 3000 rpm will be too fast. I would think about running a transfer pulley set up to allow for changing speeds to what ever you find works best. As a rough guide I would expect a rpm of around 1500 would be a good starting point for most applications as long as the motor has sufficient horsepower. The pvc pipes do work well for the dust extraction and they are attached to a 2 hp extractor unit. -
Mastrotto Adria Double Dollaro Leathers $2 per foot

Darn that is some nice looking stuff. Wish that pond was not so large, for that price . I got no plans for overseas travel but if I ever get over there I am gonna visit for sure. -
Sanding Edges of Shoes
RockyAussie replied to TomBanwell's topic in Shoes, Boots, Sandals and Moccassins
Yes I believe that rpm speed is way over ideal. You can get a crepe rubber stick for cleaning the sandpaper up which can help but overall a finishing machine would be the best bet really. They generally are good at removing most of the dust as you sand at that is more important for your health. -
Manufacturer's Supply Company Bell Skiver Project
RockyAussie replied to mcguyver42's topic in Leather Machinery
That is what I was afraid I might see. Without picking up another head somewhere I think it will be pretty hard to get going but that said ...the vacuum part and table of it could be worth an easy $200+. If here in OZ I would pay that and more. IF you could work in close with one of the dealers and if one is close by then you may be able to find some compatible parts.- 20 replies

Manufacturer's Supply Company Bell Skiver Project
RockyAussie replied to mcguyver42's topic in Leather Machinery
It has some similarities to a Fortuna skiver but I can not see from your pictures how the sharpening stone can be driven. Normally there is a belt that feeds inside through the machine and that hooks over the back right pulley set up. Some other machines run off a clutch that is on the right front pulley but I see no front control knob to actuate it. Otherwise I see a fair bit to do but the part that worries me most is that there is no cover over the back gearbox that transfers the motion to the feed roller. If you turn the back right pulley clockwise by hand does the feed stone revolve alright? The bell looks to have plenty of metal left so that's good. The left cover that is missing should not matter to start with. I will try and load up a pdf file that may be to large as that may help a little. Best of luck.Fortuna 50 p ag.pdf- 20 replies

Help! Rolled edges: Made a thing, not happy.
RockyAussie replied to YinTx's topic in How Do I Do That?
I would be doing a binder edge either fabric tape or leather if you prefer. I am not sure but you may have come in a little too far from the edge when connecting the gusset to the front section. 1/8" in would be my guess would work best which I think would make the gusset area not stick out so much. NOT to bad overall though.. -
Sometimes I use a vinyl and sometimes along with backing with stiffeners but having some cheap real leather is the best way to go. If you know that you are only using it for pattern work prototyping you can normally pick up crappy leather that nobody wants to buy for a giveaway price. If he is close enough call @nstarleather or email him as I think he may be able to help nstarleather@shtc.net

when you have it set up and working and you are familiar with how to get it to print let me know if you need some help. I would be happy to do that for you. Show me the type of product you want to do and any ideas of the pouch design and I will do my best. The customer is very pleased which is always a +. The tabs I have not done before but for doing a lot in a day it was the best I could think of and so far it works well. For those into 3D printing ....the tabs are solid and done in 2 parts then glued together. This is to give the best strength to the pressure pull on the tab. The other parts are 2mm walls including top and bottom with a 30% fill. All up this one chewed up about 700 grams. Took longer to print than it took me to design.

This video shows how I have made up a 3D printed mould with retaining clips for wet moulding a pliers pouch. The customer for this job wants to cast up to 28 pouches in a day which will require a few moulds to allow some drying time in between castings. This is also why I designed the retaining clips to allow for a quick clamping method which would not require any extra hardware to be used between castings. This is my first prototype version at the moment and I will try and do up a finished pouch by Christmas. If you do any pouches on a repetitive basis and would like to know more contact me. Follow my channel if you want to see more on how it is made.

Doubt it will help by other comments on this page but I have to say that like a lot of stuff these days the whole world just seems to be going nowhere very quickly. https://www.facebook.com/theupsstore/
