Tablesaw Splitter Jig
Description
The start of a jig for installing "splitters" in custom-built table saw blade insert plates. This was modeled from a picture in a catalog, I don't own a commercial jig. This jig will screw to a thin sheet of ply/MDF positioned square with the fence, fence adjusted so the blade centers in the rectangular groove. Four holes then drilled with a 7/64" drill locate the position of a splitter. The actual splitter part will insert into those holes. The six mounting holes are sized for a #12 screw. **NOTE** I don't know if this will work, if the splitter part will be strong enough to not just snap off in use. The commercial products use plastic-coated splitters with metal cores. **Update - 2019-10-02** Two splitter versions are available: a regular and a reinforced ("cored") version. The splitter body is 1/64" under the standard 1/8" kerf width. The regular version is plastic only. Maybe it is strong enough, maybe not. Print another one if it breaks. The reinforced ("cored") version is modeled such that a standard-sized 1.25" 17 gauge (0.055" diameter) finishing nail (with point and head removed, length cut to 30 mm) can be inserted into the centers of each pin. This should give the splitter some extra lateral strength. I needed to open up the pin-center nail holes with a #53 drill bit, then I secured the nails with some CA glue. Finishing nails (e.g.) - https://www.mcmaster.com/97828a637 Print the splitter pins-up. I printed at 80%, brimmed.
