What is the best method of cutting 3/4" thick MDF to produce circular/elliptical speaker plates ?

Question

Jigsaw or router, or is there another alternative?

Answer 1

Router by far!

I have built probably over 100 boxes and I will tell ya.... After the router came along that jig saw crap is for the birds.... If you get a router to do your cuts... The jasper jig on partsexpress.com is seriously that best $26.00 I have ever spent on car audio!

Answer 2

Use a jigsaw with a blade for cutting metal, which will give You a smoother cut. You could use a router, but You'd have to use a jigsaw to cut the rings which guide the router.

Answer 3

plunge router or a band saw or cut the edges on the inside of the line with a hole saw and then cut with a japanese pull saw or a coping saw ,, and then sand or router to make circles drive a nail inside the circle attach a string to a pen then measure the string to half the total size of the circle now hold the string on the pen or tape it then turn the perfect size circle

Answer 4

The easiest way to cut plywood is with a rotozip saw. If you don't have one maybe a friend does. there is a attachment for them designed to cut circles that works great. otherwise use a jig saw with a fine or plywood blade.

Answer 5

Plunger router with a flush trim bit and this jig;

Answer 6

Either one, but create a compus using spare wood. One end secured at the center and the other secured at the tool.

An elliptical shape will require a string and two points at the middle as foci. (see math books.....)

Answer 7

Circular - Just use a circular saw in a drill.

Router's the best for elipses
