Routing advice

[Glen1]

Just after some advice. I currently have a sub using a Peerless XLS driver. I had the box built by a cabinet maker who had the driver hole recessed so the driver was recessed into the hole. I've decided to go for a Rythmik 12" sub and have to alter the driver hole as the Rythmik is a little bigger. Without a template and not doing it free hand how do I open up the driver hole but just a little. I have a router.

If it includes the rebate as well, the best is to create a new centre to swivel a circle jig (like the Jasper Jig... Soundlabs sells them or you can make one). Add a piece of MDF, glued or screwed behind the baffle, and drill a new perpendicular swivel hole on centre (see the pic).

If it's just the inner diameter then you can make a jig out of some MDF, clamp it on the box and use the router with a jig guide.

sorry to but in..... how did you get the not fully rounded hole

"have the jasper jigs btw!

[rabbitz]

Made up a jig from 6mm MDF using a jigsaw. Clamped the jig onto the box and used a jig guide on the router.

It was for a Peerless HDS drivers like the one in the pic. Not as bad as doing a Vifa D26NC.

That will be these suckers. I'll take some pics tomorrow of the jig and router jig guide.

yer they look nice my self would maybe like a different colour but still look good


yer i was thinking to get around the rebate bit was to cut the round hole "with jasper circle jig" and have the frame on the out side and then a 3m black perspex"plastic sheet" or something cut with the not fully round shapes so it would look rebate or what ever the proper term is

This is the jig and router jig guide that attaches to the router.

.... and how it's used.

so u have drew out a template in mdf then use a router black thing that then would leave enough for the rebate part
