Whats the best way to cut
1 Attachment(s)
Intricate designs in 3/4" plywood?
I got a 9" Ryobi bandsaw and I swear the thing will be lucky if it can cut a circle smaller than a coffee can. :wall: Something like this. |
if you don't have a bosch jigsaw find someone who does...they make a blade that cuts on the up stroke and down...its mabe 3/16 at most wide and will cut a quarter size hole smooth as silk.

thanks, I'll track down a jigsaw
|
That's not going to hold flowerpots is it?
|
the boat is victorian Lol

Depending on the size of those cut outs, can't you do the round with a hole saw or forstener bit and just use the band saw to open them up?

Thats what I tried the hole saw and the band saw but it won't even trac strait enough to follow the slightest of lines. the blade just wonders. I can do better with a sawzall but thats not that acurate either.
Salty I need one here anyways, so If I can borrow it for the winter sure:hee: Thats the support that holds the gunnels up plus rod storage. |
Mike seems to me that you need to tune that band saw up.
|
not only that does the blade moves about without a definite destination or purpose too. :angel: Just wondering
|
Not sure if the pic is exact but on the round portions if they are supposed to be circular I would use a hole saw on those portions to keep a nice symmetrical edge and then take the jig saw to take out the Straight shots to the holes.
just a thought.. |
If you are trying to make a bunch the same, I'd use a router with a pattern bit. Make the pattern out of 1/4" material.
What i mean by a pattern bit is http://woodworker.com/cgi-bin/FULLPR...%20Trim%20Bits It's easier to get the pattern right if you make it out of thin material. Drill a hole for the round end. You only need to make one pattern, you can move it to make three rod grooves. Just make it big enough to clamp on the piece. |
Template with a holesaw, jigsaw, then router
|
Norm Abrams has a tool that will cut all three notches in a single pass :hihi:

hey freak i have the same saw as you and i got to tell you the trick.
you are using the blade that came with it are you not? well if you are you need to scrap it and go get a fine cut blade for it and all your problems will be solved trust me. i went threw the same problems and many i know have had the same problem we all made the switch and all is good now. |
My boss has a jigsaw. he's going to bring it in monday.

drift
All bandsaws have something called drift. you have to account for the drift when cutting with a bandsaw. Go Very slow. use a template and then use a router to clean it up.

otherwise, your holesaw can get you started then maybe connect it up by cutting the rest with a handsaw, do you own a handsaw? nobody seems to use handtools anymore, they work well, plenty of control and simple. It's not hard to follow a line with a good sharp handsaw, the kind your grandfather used to use. If not maybe start it with a circular saw and connect to the hole the rest of the way with the handsaw or jigsaw. What you are doing there, you should own a Bosch jigsaw anyway, I have 3 of them. good luck Mike that is about the simplest part of your rebuild |
