i am just getting into wood working and i am having a tough time
cutting a stright line even with a straight edge.my question is this
...on a board that has been cut crooked...how do you straighten out
that edge?or say you have a board where all the edges are crooked,how
would you straighten out one edge?
the easiest thing of course is to already have a straight edge you can
count on to be accurate. then you can use it as a guide when making your
subsequent jigs and such. the factory edge of a sheet of quality plywood
is usually pretty good.
for some good reading material, start here:
1. Glue/tack a piece that has a straight edge to one side, realising
how much you are willing to waste [if seeing tack-holes] if necessary,
but also judging safety ...not *too* close to the edge. Run through
the Table saw cutting the other edge first. Then use that to make
your second cut. If the one side will be hidden in the finished
piece, don't worry about tack holes.
2. Clamp a Straight edge and use a router with a straight bit.
3. I've come reasonably close freehand with a skill-saw with great
care and caution. Close enough to get a decent edge to run against
the fence for a clean cut on the other edge.
Think safety first! I've been doing it for years, and now have a
small, but clearly visible L-shaped gouge in my forehead to remind me
I'm still a Learner.
To "force" a straight edge, place the board in question
on a "cariier". This "carrier" can be a piece of cheap
1/2" mdf but it needs to be slightly bigger than the
stock you are making straight.
Using screws, attach the board to the carrier leaving only
a small amount over the edge of the carrier. This will be
the part removed. Using the factory edge of the carrier,
run it through the table saw. You will then have a board
with "ONE" straight edge. Remove it from the carrier and
using the new edge, rip the board again.
