Volute by Makita

[TimS]

I have been thinking through this jig for a while and have nearly solved the process. I thought you may have some interest so here are the images. I have yet to complete the volute on a finished neck with this jig but I have 90% iron out all the bugs save the angle for the volute cheeks which seems to be just a smidgen less than 45 degrees. I nthink I have this one ion the bag if I put angled foot of about 3-4 degrees on the bottom.

Please note that you would need to do two passes: one with the straight cutter and then the v cutter.

Really interesting solution that you've come up with Tim.

When you say that you need to put a angle on the foot, is this the plywood sled that is sitting over the head stock that the laminate trimmer is riding on, or the base plate on the router it self?

Hi Allen,

A foot on the base of the router to enable the router to lean over a litttle more. Your will notice that the top of the volute in the image was not machined by the cutter. Of course putting a foot on the router will swing the bottom of the cutter out a little however as the cutter crosses the centreline this should not be a problem.

Very interesting Tim, thanks for taking the time to post this it looks simple and effective and they are the two most important properties required of any jig.

Cheers
