Thanks for sharing this. I'm very impressed with what you managed to do with aquarium hose and curtain brackets. You gave me the inspiration to do my own double belt conversion on my old treadle although it is quite a bit different from yours. Also i have a suggestion, mount the double pulley as close to the table as practical. If the belts are a bit shorter then there will be less arcing up. Another source of silicone hose is from automotive stores in the form of silicone vacuum hose. The side wall is thicker for a given diameter and is less prone to kinking and often comes in black. Since the secondary belt has three times the force on it something a bit heavier would make sense for that belt. Not only are you creative in sewing you are also creative in engineering. Keep up the good work.
Ty for your response and encouragement. Here is what I have learned: The Double Pulleys cannot be moved closer, because then I would not be able to tilt the machine back. Also, I did try thicker belts from the 2” Pulley to the Handwheel. However, they made the Motor work harder, therefore, it get a lot warmer. I also did not get a nice slow start. So, I am finding that I need to use the thinnest yet strongest belt to achieve the best results. I plan on ordering the 6 mm silicone belt from Amazon. It has 1 mm thick walls. I may do another follow-up video after I have it installed.
