How to use a Router?

[lostdaytomorrow]

Hey guys, my dad gave me a Ryobi router for Christmas. The one with big black handles on each side in a big blue plastic case. I don't have bits for it or anything yet though. He also got me a really nice Dremel, the nicest one Home Depot sells at least. And I got about 500 attachments for the Dremel.

Can I use the router to make MDF baffles for my front components that will be mounted in the door?

Will a route cut out 3/4" MDF or do I need a jigsaw or something?

Thanks for the help. I've never used anything except a circular saw and I don't have a big shop or anything.

When using a router on 3/4" MDF, do multiple passes.

For single baffle, I hear 2 passes @ 3/8" works, 3 passes for double baffle.

A good bit to use is a spiral upcut, or a double fluted straight cut.

A Jasper jig would help a great deal to make perfect circles.

Use a circle jig to make circle cuts (obviously). I've used the Jasper but I usually just make my own jig from 1/4" MDF. I would do 3 passes for 3/4" and 5 passes for double layer. I've snapped bits trying to do double passes.

Good bits to have are straight cut (either spiral up cut or double fluted), roundover (I use 1/4", 3/8", and 1/2"), flush-trim (double fluted with ballbearing), and a mortise bit (for flush mounting).

Route slowly and be sure to have very good dust and eye protection.

So, what exactly makes it where I'm not free-handing it and it actually makes a circle? Is there a compass type thing that will make it pivot or what?

Search for "Jasper Jig". It screws to the bottom of your router and has many predrilled holes where you can attach a pivot pin. The pivot pin allows you route a circle without freehanding it.
