<<Written while you where writing post number 2, but we came up with the same conclusion:>>
Info from Micro Jig:
SP-G-P3, Green, Standard width replacement splitters A & B, 8.95.
SP-Y-P3, Yellow, Thinkerf width replacement splitters A & B, 8.95.
Free shipping and handling on both.
Heck, a complete kit each is only $24.95... Combo kit with both sizes is $44.95. Looks like since they have a combo-kit, that they imply it works with either.
If you do the math- You have a left-tilt saw. When you have a .116" blade in and the splitter is .105", you have .005" on each side. You put in a splitter .025" thinner and use a .025" thinner blade... If used in the same insert, it would be better if they molded the pieces offset to the arbor flange side, so that they were directional and sided up to the arbor flange side as constant... but even if they didn't, being they are just plastic and have some flex, they will work.
But since you now found out that your thin kerf blade would work better with a pair of stabilizers and would have to make another insert to use your thin kerf blade with an offset caused by that... Isn't that leaning towards making another zero clearance insert for your thin kerf blade offset (offset right the thickness of one of the two stiffener halves) and then buying a thin kerf MJ Splitter kit for thin kerf blades, to install in that new thin kerf blade zero clearance insert?
The parts are not interchangeable, you need a ZC insert for each set up or an insert that can be reversed end for end and do two set-ups on the same ZC insert. The pins in the bottom of the the splitters are spaced differently, wonder why they did that, Ummmm
My insert fits but the keepers (I'm referring to the pin on one end of the insert and the adjustment screw at the other end) would have to be reversed, no big deal, but I have cut all of those holes in my insert to create better air flow for the DC so, in my case I'll just make the second insert.
I paid $39.95 and freight for the complete orange kit this morning, supposedly on sale.
That's for the Steel Pro Kit.
I'll need to go to Forrest and buy the second stiffener so that I can have one on each side of the blade and of course do that before cutting into the new ZC insert which wil be made of half inch MDF.
Did you speak to the R.O. of the arbor, if you did I must have missed it.
