Hi Bruce
You can do it with a table saw but it can be tricky and not to safe.
You can do it on the router table with a quick jig and it will come out clean and true.
Use a slot cutter and the jig.
see a snapshot of the jig below.
To make the spines clean and true use a T & G set and remove the bearing from the center of the bit set and put in some small OD washers (5/16" ID and 3/8" OD) that add up to 1/4" thick spacer, or made one with some 1/4" thick plastic.
Make a pass then take it to the table saw and cut off the spline strips.
The spines will be about 3/4" wide and a true 1/4" thick.
Note*** make a test cut b/4 you make the splines you may need to add a washer to the spacer because the carb tips hang down just a bit.
Bruce, have a look see at the jigs below for a 45deg. spline
You can use a slot cutter to do this job also.
You can do one at a time or as a pair, the pair way is the best ,it will line up both parts at the same time for the spline.
The 4th, snapshot is for a standard bit (1/4" or 3/8" the norm.)
