Step 8: Worm Gear Carriage Part 1
For this step you will be using the 15-5/8" length of 3/4" schedule 40 PVC Pipe.
There are two ways to layout the pipe for cutting. The easy way would be to print both pages of the the WormGearTemplate PDF document at full size and follow the
If you can't print the template document correctly, View the WormGearCarriageDetail PDF document. It contains all the details and measurements needed to build the Carriage.
If you are using the template (recomended) , make sure to drill the holes before using the cutting disc.
If you are not using the template, drill the holes last.
Use a dremel tool with a cutting disc to cut the pipe.
After the holes are drilled and the pipe cut out, Countersink the 3 1/8" holes from the
inside surface for #6 flat head screws. Countersink the 2 1/16" holes from the outside surface for #4 flat head screws.
