Description
For Sale: All Nation’s Weaver Sprockets Replacement for Chain Drives PN#518AN
The original sprockets were 8 teeth on the top and 12 on the bottom. Now those can be changed if one wants a 1:1 ratio we include 12 tooth sprockets top and bottom or a 10 tooth sprocket for the top. Note that the diameter of the bottom drive shaft is larger than the top. Obviously, if one goes with different sprockets, the length of the chain will vary.
All 3D printed parts may come with printer plate build material and brims that will need to removed and any thread cleaned up with a file. With the right size triangle file, the teeth can even be burnished. The inside diameter of the holes on the sprockets are slightly under size so that they can be touched up with a file and hand fitted to the upper shaft with the knurl. The bottom shaft does not have a knurl, so one can force press it on, risking stress that may crack it. However, I recommend touching it up with the round file so that you have a tight press on and then applying a little CA with baking power around the joint. Always degrease before gluing.
Parts list:
3 Upper Drive Shaft Sprockets 8, 10 & 12 teeth
1 Bottom Drive Shaft Sprocket 12 teeth
