  1. In his day and age getting a machine for $200 that works and that can handle 10-12 oz leather is as scarce as hens teeth. The amazon machines, Chinese Patchers, I call them the "Tinkers Delight", which for most are going to be a waste of money but are great frustration generators. If you moved your budget up to the $1000 mark you could probably get a good used upholstery class machine depending on where you live or a new manual class 441 like a Tippmann Boss. kgg
  2. The torque of a brushless is greater then one with brushes. However the brushless have a higher startup speed then the brushed servo motors. Personally I prefer the brushed servo motor over the brushless due to it's simple design. No electronics to add another layer of possible problems. But then again I don't need / want the needle positioning feature and the one that came with my TSC-441 clone is filed in the "special" drawer. That said most of the world except for North America are using the brushless and they are becoming more popular here as they are all being import from places like China. If I had to choose I would personally go with the Consew 550 watt that @Wizcrafts recommended. The next option would be the Reliable 6000SM. kgg
  3. To narrow down the noise what I would suggest: Remove the Belt from the speed reducer to the sewing machine and run the motor. i) If the noise is still there then it is coming from either the speed reducer or the servo motor. Then remove the belt from the servo motor to the speed reducer. If the noise is gone then it is probably either a misalignment of the belt to the servo motor from the speed reducer or the the bearing in the speed reducer is dry and needs a drop of oil or a bad belt with a lump where it ends are joined. Then check the alignment of the belt from the servo motor with the large pulley on the speed reducer. ii) If the noise is gone then it is either coming from the speed reducer, bad belt, misaligned belt or the main bearing in the sewing machine. Make sure the alignment from the small pulley on the speed reducer is properly aligned with the sewing machine pulley. kgg
  4. What I would do first is install a servo motor and dump the clutch motor. I then would install a servo motor either a brush type or a brushless, 550 or 750 watt. I would install the servo motor first without the 10 to 1 reducer you have as it probably is going to provide way to much speed reduction as the typical reduction is 3 to 1. If you go with a brushless I would suggest going with the 12 coil Reliable 6000sm ( https://reliablecorporation.ca/products/sewquiet-6000sm-servomotor ) 550 watt or if you want to go with a less expensive option or another speed reducer contact Chris at Japan Sewing Machine ( (905) 764-0100 ). Those companies are down in the Toronto area. kgg
  5. Basically you have two main choices i) Brush type servo motor ii) Brushless servo motor Brush type servo motor have No electronic controller components. The typical size is 550 watt, use a simple dial for setting the motor speed and have typical startup speeds in the 200 rpm range. Brushless servo motors have a electronic motor control. The typical size is 750 watt, set the speed of the motor on control panel, have a typical startup speed of 500 rpms and have the built in ability of a needle positioner. The number of internal coils typically are 6 while the better ones have 12 coils. More coils the better the motor. Some of these motors with a needle positioners will not work properly if a speed reducer is added. Needle positioning feature some people love them while others not so much. Cost wise a basic brush servo motor is about $150 CAD while a 12 coil brushless servo motor is about $250 CAD. A 550 watt brush type servo motor should handle the torque needs of the Juki LU 563 without the need for a speed reducer while a brushless servo motor may require one due to the typical startup speed of the motor. kgg
  6. The Techsew 2750 is the poor cousin of the Juki LS-341. Here is the Juki manuals: kgg Juki LS-341N Instruction Manual-1.pdf Juki LS-341N, LS-341N-7.pdf Juki_LS-341N_Engineers_Manual.pdf
  7. When I compared the three machines I was going to order the Outlaw but decided against purchasing one in the end. I purchased a TSC-441 clone instead. My reasons were: i) After much thought I figured I couldn't see myself pulling the lever over and over to create a stitch. Then the machine wouldn't get used as often so it would just gather dust or I'd end up selling it. I guess I'm the "lets getter done type". ii) Greater availability of accessories and parts from a lot of different suppliers both domestically and from overseas. iii) All of the machines have a small usable throat space of something like 8 to 10 inches. All that said these machines do have there place but neither were the right machine for my needs / wants / desires. kgg
  8. The Juki LS-1341 and clone cylinder arm machines have the same top load bobbin system as the 1508. Where are you located?? Maybe there is member close to you who could suggest a dealer in your general area. kgg
  9. The problem I found is that if you are a little tired, have a little leg jerk or otherwise slip a little bit you stand the chance of royally screwing up the piece you are working on. The servo motor provides much better control right out of the box. The price of $195 for a servo motor installed is a decent price. Definitely worth the investment. I assumed the table was larger as you said it could be cut 8 feet (8'). Yes the standard is approximately 48" x 20". Unless you are really limited in the space you have I wouldn't bother. kgg
  10. Yes and rightly so. The worst for trespassing in my rural area are the snowmobile users then the citi-idiots during bird / deer hunting season then the ones cutting down tree's without permission (tree poachers) then the truffle hunters then the garbage tippers then the illegal grow op's and of course the deer poachers. The only ones that I give permission too travel my land are the wolf/coyote hunter group, a trapper and the owners of the adjoining farms. kgg
  11. Chances are a lot of those are coming from places like China. Try Aliexpress. Example Link: https://www.aliexpress.com/w/wholesale-Horse-hair-brush.html?g=y&SearchText=Horse+hair+brush On the left side are the option for Delivery / Shippining Country / etc. kgg
  12. Both the 1541 and 1508 should handle the thickest you want to sew in webbing. It's the leather where you say "Possibly thicker". If I'm not mistaken both machines have rated sewing thickness of 3/8" (9.5mm). Since you do want the "unicorn" I am going to suggest you consider a cylinder bed machine with a table top attachment. You will then get the advantage of a cylinder bed with the capabilities of a flatbed something like a Juki LS-1341 or clone. Why are you planning on using a top thread different then the bobbin thread? The strength of the stitch will be that of the smallest thread and probably harder to adjust top thread and bobbin tensions. Thread info: i) Tkt 40 is equal to V69 with a typical breaking strength of ~5 kg (11 lbs) ii) Tkt 20 is equal to V138 with a typical breaking strength of ~10 kg (22 lbs) A good cross reference chart for the thread and needle size can be found at https://www.tolindsewmach.com/thread-chart.html kgg
  13. Whats your minimum and maximum thickness going to be for the webbing and the leather going to be, including any seams and the thread size you want to use. My experience with the Juki 1541, great machine, is it hates thin items particularly fabric so I can imagine the 1508 would act in a similar manner. I added a Juki 1181n to take care of the smaller stuff so I wouldn't have to make time consuming adjustments when going back and forth from thin to thick. kgg
  14. The warranty and delivery at $750 is a decent price. Needles determine what size of thread you are going to use. Typical would be V92 and V138 thread so you would need needle sizes from #20 to #24 depending on thread and thickness being sewn. For Fabric you would need system 135x17 and for leather system 135x16 needles. A good needle reference chart for thread size can be found at https://www.tolindsewmach.com/thread-chart.html My suggestions: i) Since this machine has a non standard size table I would ask them to swap that table for a normal size industrial sewing machine table. That table does suggest that the machine was used in production environment. ii) I would venture to guess this machine has a clutch motor so ask them what the cost of a 550 watt servo motor would be?? The retail price for a servo motor would be somewhere around $200 CAD. If their price is too high then I would strongly suggest buying one and installing it yourself. The learning curve of using a clutch motor can be steep and they are always running whereas a servo motor will give you the control that you need as well as being almost silent when running while you are sewing. I think @MtlBiker may know of un-used 550 watt servo motor. iii) Get them to go over the machines operating the basics of threading the machine, winding a bobbin, installing the bobbin, oiling etc. kgg
  15. The Relsew if I'm not mistake was sold by Reliable out of Toronto many years ago before they had their own line of clones. The Relsew is a drop feed sewing machine made for fabric and has a clutch motor. The Juki 5600N is also a drop feed machine made for thicker fabrics. I would suggest seriously looking at the Juki 563 and maybe post some pictures of the machine prior to purchasing. kgg
  16. It is always nice to see how members modify equipment to suit their needs. I did look at the desktop style hydraulic press but I choose to go with the more conventional bottle jack and floor style. What I did like about the one you are look at is the head can be moved from side to side. kgg
  17. Do the math again including the total running length of the holes. Including the holes and depending on whether the holes are punched or perched that may put you very close or over the 1.5 ton rating. Yes you should be able to emboss quite easily. kgg
  18. To help you decide I used the following formula when calculating my tonnage needs for a clicker press. F (pressing force needed) = S (shear strength of leather / 2) x L cutting (running) length of die X T (thickness) of leather in inches X Sf safety factor Example for 10 oz leather with a 3 inch square die. S (shear strength of 10 oz leather) = 2900 psi L cutting (running) length of die = 12 inches T (thickness) of 10 oz leather in inches = 0.156 inches Sf safety factor = 2 F = 1450 x 12 x 0.156 x 2 => 5428.8 pounds (pressing force) So the question is the manual clicker press rated in Imperial tons or US tons? Also what is the price of the manual clicker press. 5428.8 pounds = 2.42 tons Imperial tons, 2.71 US tons So the question is the manual clicker press rated in Imperial tons or US tons? The reason being 1.5 US tons equals 3000 pounds while a 1.5 Imperial ton is 3360 pounds. Whether or not the manual clicker press will work is going to depend on both the bed size of the manual clicker press and the thickness of the leather. I decided not go the manual clicker press route even though a 5 ton probably would have done for the main reason, Money. A 5 ton would have cost north of $3000 Canadian and would have been a one trick pony. That cost versus converting a 20 ton hydraulic shop for about $700 Canadian total including cost of the shop press when I'm finished. Hum. I'm at about the 75 percent completion mark. kgg
  19. I have to disagree. The Reliable Barracuda is just another clone of the Sailrite LSZ and made probably in China with poorer quality internal components then the Sailrite's. The OP indicates she wants to sew up 12 oz leather. The thickness of 12 oz leather is approximately 1/4" and the portable walking foot sewing machines can only handle about 1/8" thickness with a max thread size of V92. Also as the thickness of the item being sewn increase the stitch length will decrease so it can be difficult to maintain a constant stitch. These little machines were intended for sewing sail fabric. Besides using a Singer Class 15 bobbin another problem is the presser foot and feet dog are very aggressive and will imprint the leather. Since this is going to be your main machine you will need to increase your budget even for a used one in most locations. As far as space goes most industrial sewing machine tables take up a space about 2' x 3'-6" and noise isn't a consideration as with a servo motor they are almost silent. kgg
  20. The Omgea WF22ZZ is a Sailrite LSZ clone from more then likely China. The Omega 307 is a domestic drop feed with zig zag. I personally think you will not be pleased due to their limitations as neither are industrial machines. With your budget I would suggest dropping into a industrial sewing machine repair / service center and see what they have available in a used industrial sewing machine. There should be quite a number of them in Montreal. If you find a machine and aren't sure of it's abilities just ask on the list before purchasing. kgg
  21. Nicely done and nice selection on the servo motor. kgg
  22. Sorry to say not up here in Canada. Your property, your liability even if the client / visitor is the negligent one. Even giving someone permission or unknowingly someone travels your land for hunting, etc it is a liability to the land owner. It's to the point you can't even help someone who gets stuck in the snow or drove off the road. If you use your tractor to pull them free chances are you will be accused of causing the damage to the vehicle even though it was caused by the driver and windup paying for the damages. Happen to a farmer neighbor a few years back. Gone are the days of being neighborly. kgg
  23. Some machines can be very particular in the way you install the bobbin so it unwinds counter clockwise or vise versa. I would suggest installing the bobbin in the bobbin case the opposite way and see what happens. This maybe as simple as the bobbins are not to spec as in too small, center hole to big, not balanced, out of round. I would suggest replacing with a Juki spec bobbin. A couple of photo's of the threading path from the spool of thread to the needle maybe also helpful. kgg
