    Default Recessing control knobs

    Hi.

    I have recessed control knobs using a router bit in my drill press.....and then I thought "why not use a ROUTER & plunge it going a little deeper each time".

    Then I thought "there must be issues with this else no one woud use a drill press"...

    so what issues might there be using a plunge router to do the recessing?

    I've just used the drill press as its easier and I can see clearly without having try look through the router base.

    Tomorrow I'll be doing this, I'll take pics and post them in the tassy blackwood thread.

    I drill the hole the size of the bearing that is at the the of the bit, which is just a curved router but. The bearing fits snug into the hole so the router bit doesn't bounce around.

    Luckily the pots I use are the same size hole, but if I'm recessing a larger switch I'll then re drill the hole after the router bit step.

    In my latest carve tops I've had to recess my mini toggle switches a couple milimeters and I did that with a forstner bit.

    On the topic of forester bits, my set was blunt as butter knives, I replaced them with saw tooth bits, I am very impressed by them! Although the smaller sizes in the set are still classic forstner bits.

    I use the router with a bottom clearing bit (rounded corner) with a router bush and large round template hot melt glued to the top. This produces a dished recess.

    there are several ways to do this..but first

    Most forstner and saw tooth bits are far from sharp out of the box, they are easy enough to sharpen with a small mill file.

    By far the easiest way to sink knobs or do almost any recess is to cut the large hole first then the small one.

    If you are using a forstner, saw tooth or a hinge sinking bit.....best to cut the recess as deep as required then use the centre point mark to drill the shaft hole.

    If ya want to do it with a router, by far the best option is with a template.

    clamp the template on and it matters little which order you do the holes......you can change the size of the hole you are cutting by changing the bit or the guide or a combination of both...and they will align perficely

    cheers
