i built a wood model of the slide when i began building my splitter. this gave ma an idea of what it would look like, what problems i might run into and the exact size of eveything i needed.
i read some where at this site that some one once recommended putting a slight inward angle (maybe 7 degrees) on your push plate and a slight angle on your wedge. kinda like this: /______\
that way, it forces the wood to remain secure between the two. theoretically, it sounds like a good idea, unfortunately i didn't do it...and i wish i did.
I read about that also but after i had built mine. I take it i didn't miss out on much?
