I want to put a foil on one side of my steering paddle. Even if it doesn't make it scull any better, at least it will look more like the real thing instead of a cricket bat or some sort of fraternity initiation weapon.
But test runs on pieces of cheap plywood aren't coming out the way I hoped - which was for a reasonably smooth surface.
Instead, the router bit's depth seems tb varying by about a half mm for no apparent reason as in http://tinyurl.com/7ly82xj
The jig is no prize: http://tinyurl.com/7bdr36n
The unevenesses in the jig pic just referred to are exaggerated. Things got better when I bought a longer router bit which permits doing away with the padding under the work and the rails on either side.... but the first pic shows that it's still a problem, albeit less of one.
Before I spend a lot of time trying to make the jig more precise - or wimp out and just sand the flawed result to shape; I would like to find out if maybe there's some basic error in my logic - as in a flat router plate riding on a curved jig.....
I can't replicate the height diffs by rocking the router though... it's more when I move the jig fore or aft or work up against the fore end vs the aft end... but I still can't replicate...
Has anybody been here?
Maybe some typical noob mistake?
