  1. My tips for a "machine" look with Saddle Stitch

    Sometimes it is nice to be able to have a hand stitch mimic a machine when there are specific areas on a piece that you can't do on the machine but want to match.
  2. 3D print for patterns

    Most of the models you might 3D print for leather working really don't require a very in depth knowledge of CAD. Start off by making yourself some cutting templates. These are really just 2D models with the only 3D aspect being thickness. To make a cutting template you begin with a sketch of what you want and then make it 3D using whatever the extrude feature in your program is called. My favorite program is SolidWorks but there are a bunch out there and they all basically do the same thing. Once your model is complete save it as a .stl file. The .stl file is the file type the printer reads. You can either use the software that came with your printer or an after market program to prepare the .stl file for printing. I use a program called Simplify 3D. It is easy to use and is fast. If anyone would like some basic instruction on how the process works, send me a sketch of what you want to make and I will lead you through it.
  3. 3D print for patterns

    I have been printing 2D and 3D guides and molds for my leather work for 4 years now. I rarely make something anymore without making cutting and stitching templates and male and female mold patterns first.
  4. Oops...

    First use a syringe to inject some medium viscosity super glue into the slit and then press it with a roller after that make your decision.
  5. Ordering leather online..

    Horween Bighorn Latigo is by far the best I have used.
  6. I've been making similar plates using 3D printing.
  7. Cast Iron Tippmann Boss For Sale

    The cast iron Boss is located in Moscow, Idaho. I will ship to anywhere in the US for actual shipping charges via UPS ground.
  8. Cast Iron Tippmann Boss For Sale

    I have an original cast iron Tippman Boss for sale. The machine works perfectly and includes some machine upgrades as well as a selection of spare parts, accessories and supplies. Included with the machine are a material guide, stirrup plate, left, standard and center presser feet, needles and extra bobbins. Don't let anyone mislead you, these machines are neither junk or boat anchors. Set up properly they make a nice top and backside stitch as evidenced by pictures posted on this site by people who have taken the time to learn how to use them. I have posted front and back pictures of a multi tool sheath that I stitched with this machine as an indication of what it will do when properly set up and used. Price: $1000.00
  9. Does My Bottom Stitch Look Right?

    What weight of leather and size of thread and needle are represented in the photographs? What kind of needle point are you using? At first glance it looks like the thread and needle size are too big for the thickness of leather being sewn. It is difficult to keep the needle from tearing out the back but I think most machines can be set up to do better than what yours is doing. I am no expert but there are others here who are and can probably tell you exactly what you need to change.
  10. I do all of my pattern and mold work in SolidWorks, a 3D CAD program and then I 3D print cutting templates and molds. The cutting templates are typically 0.1" thick whith a little handle on top to hold on to them. A typical cutting template costs maybe twenty five cents to print and a three or four piece mold set maybe five dollars. I find that a lot of errors can be caught and fixed in the modeling process and the 3D printed parts are a good way to improve accuracy and speed up production. These days I almost never cut without using a plastic template to guide the knife and for molded things like sheaths and holsters I always print a mold set. If I have something I am going to make a lot of I may have as many as ten 3D printed parts, a combination of cutting templates, molds and alignment jigs. When I am designing my templates and molds I include the pattern for any design or stitch lines in the part. The 3D printer will print a raised line on the part as narrow as 0.4mm so when you lightly press the template on the leather piece to cut it out the raised part will leave a light impression that can be used as a guide. If you want to sink your stitches into the leather you just print the raised part a little higher and press it a little harder into the leather. This takes some practice but eventually with one press you can make a groove for the stitches and a guide for sewing at the same time. The beauty of this process is that using a CAD program you can make your designs and patterns perfectly symmetrical; all of your arcs are tangent and lines are straight.
  11. Campbell Lockstitch Machine For Sale

    I am interested in purchasing the machine. Can you email me so we can set up the deal?
  12. Campbell Randall Harness Stictcher

    I've looked at the Union machines but they just aren't very well suited to what I do. Don't need the speed so unless I could get one really cheap (~$2000) I would rather spend an extra $1500 and get a Campbell-Randall.
  13. Union Lockstitch Heavy Duty Stitcher

    Seems like it would be difficult to wear the paint off it in 50 hours. Is that 50 hours since you have had it or 50 since being rebuilt or what?
  14. I should set the square so that it is along one long strap side and the bottoms of the two legs of the punch? Yes. Make sure the amount of punch overlap is the same on both sides of the strap. I use a drill press to push the punch instead of a hammer.
