  1. Mildew overnight is rather unusual. Chances are some specs of iron got onto the surface and reacted with the tannin in the leather to produce the black spots. As Sylvia says, use oxalic acid to bleach it out. About a teaspoon per pint of water is usually strong enough. In a pinch, use lemon juice. Iron and tannin is the process for using vinegaroon to dye vegtan leather black. You will find it interesting to look up and read about it. Lots of threads here on how to make and how to use. Tom
  2. Welcome to your new addiction. Let the cb sit for a couple days for the oil to be evenly absorbed. Always go light on the oil as too much makes it soggy! What town are you in? Tom
  3. Holding a hot branding iron on too long will burn right through the leather. The thinner the leather ... Easier to burn through. Also leather shrivels up and shrinks. Just touch the iron and remove. If not dark enough, reapply for another touch. They should do some practice on some cut offs from the same piece first. To be able to reapply in the same position takes some practice. May be worthwhile to make a template guide clamped in position. 1/4" tempered hardboard is easy to cut and work with, and won't catch fire easily. At least for the short time the hot iron needs to be against it. Tom
  4. The smaller piece is sewn or laced to one of the flaps on the cover, leaving a pocket to slip the memo/journal notebook front or back cover into the pocket. Tom
  5. Most covers have a slot where you slide the notepad back cover into it. Picture or diagram would help for those of us that don't have that kit. Tom
  6. Cowboy 227 and Techsew 2700/2800 are the same basic machine. I have a 2700. Works well for me. If you ever sew 8 oz, single layer hard temper or 2 layers, get the pulley reduction kit. Tom
  7. Have you looked at Al Stohlman's encyclopedia? https://www.leathercraftlibrary.com/p-1128-the-stohlman-encyclopedia-of-saddle-making-volume-1-by-al-and-ann-stohlman.aspx Three volumes. Also there are sites selling DVDs. Tom
  8. Do a search here. I recall seeing a post about sharpening bell skivers. After the initial sharpening, there is a stick used to take the burr off. The post was probably within the past 3 months. Tom
  9. Welcome to the forum. Let's see some photos, especially when you do horse carvings. Tom
  10. I think the <return> key not working is a problem with MS IE. Try holding down the <alt> key and typing "010" on the keypad. This is the code for a line feed (LF). "013" is the code for a carriage return (CR). You can try it too and see if one or the other works. This only works on PCs, not Apple products. Tom
  11. Brown paper bag works well for burnishing the thread too. Tom
  12. Look pretty nice. Tom
  13. By sized I'm supposing you mean cased. The leather should be properly cased before tracing your pattern, and thus still properly cased for all your swivel knife work and stamping. Tom
  14. Pretty fair job for doing new stuff. Two things stand out. Bevelling is choppy. Either was still too wet, or need more practice to get it smoothed out. Can run over it with a modelling spoon to smooth it out. Second item is the raw edges of the leather needs to be burnished. See http://leatherworker.net/forum/index.php?showtopic=18101 for a tutorial. Keep working at it. Practice makes perfect. And, welcome to the forum! Tom
  15. As the leather heats up, it gets hard, warps, and chars. As plastic heats up, it wrinkles and burns, not just char. In both cases, sample held in open air. If held against a table top, tests won't be as effective. Tom
  16. A certain BB phone in a tight case will lock up. Have to remove the battery to reset it. So, yes, be careful about how tight it is and whether the buttons are being held in. Tom
  17. Really depends on what you want to be visible. Some cases you may like the matte, in others you may want to see the shiny side. If you are gluing the shiny side to something, then rough it up well so the glue will adhere to the surface. Tom
  18. I'd heat it and buff the heck out of it to both work it into the leather and remove the excess from the surface. By the way, products that have been finished with a lacquer don't absorb oils and greases well. Same applies to woods finished with a lacquer. Oils sit on top and get sticky instead of being absorbed. Tom
  19. Clutch motors have been around for many years, very reliable. The inertia of the rotating mass helps punch through heavy or harder material. Just hard for us to get used to feathering the clutch and maintains control at low speeds. If you have a 3" pulley on your motor now, a 2" will reduce the top speed to 2/3 of what it is now, still quite fast, at least for me, but at least a little more manageable. Low cost servos are relatively new. Some cheap ones have had problems. Old clutch motor ... throw it away unless you know someone that needs one or can find another use for it. Tom
  20. Canadian source: Princess Auto has a 12 piece drive punch set for $16.00. Sizes from 1/8 to 3/4". Made in China. Knurled handle. Need sharpening, but what do you expect for the price? 3/4" on 8 oz leather, took around 20 hits with a 1# dead blow hammer versus 3 hits with a sharp arch punch. So for the beginner or for occasional use, I think it's a good deal. http://www.princessauto.com/pal/en/Sets/12-pc-Hollow-Punch-Set/2920169.p Tom
  21. Put a small 2 to 2.5" pulley on the motor whether you use the original clutch motor or a servo motor. If you want to run even slower with the clutch motor, then you put a pulley speed reducer set between the clutch motor and the machine pulley. For the light weight sewing you are doing, a servo with a 2.5" pulley should be fine. No additional speed reducer pulley needed. Rheostats or varac transformers can be used. There is a risk of overheating the motor. The motor has a cooling fan. If it is running too slow, it will not provide the required cooling. Running an induction motor (the kind on your clutch motor) slow also causes more internal heating in the motor. Don't expect the motor to be able to run at half speed. That is probably too slow to provide the cooling it requires. I have a digital servo on a Singer U20-33 (It is a high speed commercial sewing machine used for draperies and dress making originally, came with a clutch motor) that I use for wallet interiors and such. This is like my servo http://shop.raphaelsewing.com/index.php?main_page=product_info&cPath=2&products_id=293 This is a pulley speed reducer http://shop.raphaelsewing.com/index.php?main_page=product_info&products_id=354 You can build your own speed reducer if you are handy with tools and have a source for the hardware. See http://leatherworker.net/forum/index.php?showtopic=45336&hl=pulley#entry284770 post #11. You are probably further ahead time wise to buy the set already built. Tom
  22. White or yellow? Yellow glue is usually the woodworker's type. Dries stiff and cracks when bent. White glue usually dries flexible, so shouldn't crack. But, I suppose amongst all the manufacturers, there are sure to be disparities as to how their glue dries and behaves. As an aside, for those interested, diluted yellow glue can be used to stop water stains on your ceiling from showing through your new coat of paint. Tom
  23. You need a small pulley on the motor to reduce the machine speed, about 2". Then you may need a shorter belt. Changing from a 3" to a 2" pulley will reduce the belt length required by about 1". Your mounting bracket might have enough adjustment to accommodate the change without a new belt, needs to be able drop down 1". With clutch motors, you slip the clutch to run at slow speeds. Ever drive a car with a manual transmission? You slip the clutch to get started. It takes practice. Sometimes you may be able to adjust the clutch mechanism to make it easier to feather (or slip) the clutch. Pulley reducer set may be around $125. And you need to get 2 belts. You will have to measure to figure out the belt sizes. Servo motor is around the same price and up. Servo is easier to operate. Still need the small diameter motor pulley. Depending on mounting and range of adjustment, you may need a shorter belt. Tom
  24. The trucker set the pallet on the curb for me, I broke it down and brought in the table, head and boxes individually. Tom
