Toothed, Bead ,Chain Belting …oh MY !
Since our quest is to lower the cost and improve operation of our RepRaps I felt the need for an alternative belt to what’s currently being used.
Long ago on one of my parts quests I picked up some “Diamond Braided Rope” as a possible drive belt or maybe used in an emergency to fix a RepRap. My belief now is that it’s a very good replacement candidate. The numbers speak for them self. I recently ordered Tooth Belting @ $1.81 a foot, plus shipping, taxes etc. The Braided Rope I purchased cost only $1.00 for 10 feet of the stuff.
Further, this might be a superior product for RepRap as seen in the general specs.
¼” x 10'feet
Braided for Strength
100% polyester strands
Resists rot, mildew, oil, and gas
300lbs working capacity
On the minus side that Red & White is ugly and changes to a V type pulley system would need to be made. It’s made in China, so maybe a pure color is sold someplace.
One feature I really like is that the material is very RepRap like. Looking at the pic you can see that the manufacturer hot slices the material for packaging. This is very advantageous for us. Using a hot means we can melt the polyester to any part we might wish. If we wish a continuous belt I would just butt the two ends together and melt them. If looks or an added protection is needed, then put the seal inside some shrink tube and presto you have a dirt cheap continuous belt.
Another feature: This is round material and therefore makes it superior in looping compared to toothed belts.
Where to buy? I purchased these at Harbor Freight Tools Item number 96186. Also sure these are available at other locations.
