I tried to build a 45 degree zero-clearance insert (ZCI) today for my zipcode saw. I used 1/2" MDF, used a flush-trimming bit and it fit perfectly. Since my full sized blade wouldn't fit, I used my 8" dado blade to start the slot, and then I ran into trouble.
I cannot get my 10" blade and the ZCI on simultaneously, even with the slot started. I did some looking earlier and found this thread:
http://www.sawmillcreek.org/showthre...earance+insert
but that dealt with getting the slot started. I experimented with the suggestion in the thread to cut a recess using a router, but at 45 degrees, a 10" blade is about at the height of the table with the arbor all the way down. It is physically impossible to fit the throat plate on -- the blade gets in the way. Maybe it is my saw -- I don't know.
So, for those of you with ZCI's for 45*, how do you get a full sized blade on?
Cheers,
Chris
If I were to rout out a recess deep enough, well, I would have to cut all the way through, thereby defeating the purpose.
