Here you go. ------------- I have not failed. I've just found 10,000 ways that won't work.

thanks, ive read that post and was going to do that, but our router doesnt have the eye holes to put a threaded rod through. I was thinking about taking a 1/4" board and cutting it the same shape as the base and maybe 16 to 17 inches long from the bit and drilling holes in increments of 1/4 inches -------------

If you are going to make a custom guide/template and you project requires accuracy, make sure that template is accurate as well

Holes 1/4 inch apart will give you only 1/2 inch intervals. The thing I posted a link to gives choices in 1/4 inch intervals. Plexiglass will last much longer than any wood.
