I am interested in cutting arches, like arches over a doorway, curved
railing on a deck (top rail is simply 5/4 x 6 cedar, no fancy detail), and
other similar projects using straight flat stock (or multiple pieces as
needed) turning into curved flat stock. I looked around the web a bit, and
can't find much in the way of here's what you need to make/cut/shape an
arch, and here's how to do it.
I'd like to know what tools are best/recommended for this, and one of the
projects involves 2" thick mahogany, so I have to be able to accommodate
that. Also, any suggestions/tips on how to get the smoothest/most accurate
arches would be greatly appreciated.
Each project brings on a totally differant set of circumstance and differant
methods of procedure.
Do you have some plans, or sketchs that you can e-mail to me and I could
then give you some guidence
All I want to start with is making a flat board, say 5/4 cedar x whatever,
into an arch, say, 3' wide with a cord of 4". For tools, cutting the arch,
I am guessing a bandsaw would be best, and for smoothing the arch, I am
guessing a shaper (or a router table with a straight bit). Any other
suggestions are welcome.
Routing against a pattern gives the best cut and the pattern is reusable.
There are router bits up to 2" long, so you can cut something quite thick by
going from both sides.
Rough cutting with a sabre saw will save wear on the router bit.
Dawn breaks over marble head! I couldn't figure out how the pattern would
help...but...if my router bit has a bearing on it, I can ride the bearing on
the pattern! Duh! That would work great! I'm not sure a shaper would be
able to do the inside arc...so my router table (which I do have a 2 1/4 hp
router) without the fence etc. would work perfectly!
Would I be best using the largest straight bearing bit I can get?
I still believe I need a bandsaw, instead of trying to cut 30 pieces of
mahogany on two sides with my jig saw...that would get tiring... Any
suggestions on bandsaws would be appreciated!
on BS's: the new Powermatic 14" is GREAT! It's got a work light, high
table like the Delta's, compressed air for blowing the cut line clean
(runs when the motor is running), and great workmanship. Runs smoothly
like a sewing machine. Just got mine last week after given up the
shaking Delta 28-299A. To be fair, the newer Delta, the X-5 seems much
smoother than the 299-A, but not quite as nice as the the new
Powermatic. Carter guides, quick tension release lever. It ended up
being a bit cheaper than the Delta also, as it comes with a nice fence.
Miter gauge is included too. Just used mine a few minutes ago to make
some precise cuts (notches). The don't look rough like a typical BS cut
because the thing runs so darn smoothly. and that's with the included

I forgot 2 other details: there is a brush riding against the lower
wheel to help remove sawdust, and there is a 4" port in the cast iron
lower housing, just below the table. The port actually captures most of
the sawdust; it's much more efficient than the pre X-5 Delta's. I've
seen the X-5 run, but it wasn't hooked up to a DC so I don't know if
their newer port design is any better than previous models.
