What adjustment is necessary to correct a convex cut when edge jointing a
board? Also does anyone know of a site that tell what adjustments are
required to correct for different types of cuts, concave, convex, tapered
ect.? Thanks, Kevin
Jointer adjustments are really simple in theory, but can be had to execute
the first few times. The blades should all be of equal height, the blades
should be dead even with the outfeed table, and the outfeed and infeed
tables should be in the same plane for the total length of the tables. If
any of these items are out of line you will not get an even cut.
I don't know of a website the gives the error messages that you are looking
for. If you are cutting a taper the blades are too high.
A big problem that some people have with jointers is putting too much
pressure down onto the board. There should just be enough pressure to stop
the board from chattering and never put pressure at the end of the board as
it goes over the knives.
I hope this helps, and I expect that others will hop in with their
The cut you are getting is convex when you start with reasonably straight?
Normally outfeed too high.
Cut is convex on an edge which began as convex? Join the middle first,
starting and stopping short of the ends.
