Can you guess what this will do when finished?

[J E C]

I've been busy the last couple of days making this. It isn't finished yet. I still have a few components to make and I'm waiting on some bearings I ordered.

Can you guess what it is for?

Here are a few pics of the setups that I used to make some of its components.



More pictures and commentary to follow, as I make progress and us it!

I'm trying to formulate some crude guesses. So far, fascinated.

Truss Rod route jig?

That's one thing I was thinking. But now I'm thoroughly convinced it's one of those puzzles where you have a ball or something stuck inside and you have to figure out how to remove it without using a sawzall.

Is this the JECsteen jig?

It looks a little bit like a flux capacitance routing converter.

What sort of wood is that? Did you laminate all those plies?

Some good guesses there and some were actually correct. It is a fixture for routing the fingerboard radius. This will do a single radius or a compound/conical radius on a guitar neck. I will be setting it up to do a conical radius with a 10" at the nut and an 18" at the bridge on 25.5" scale. The radius at the 24th fret will be 16".
I had originally designed a totally different design that would be possible to do up to a 24+ fret 35" scale bass neck. It would have been more flexible and adjustable but much bigger than this design, and I don't have much room. After Kramersteen asked me to draw up a design to help explain a fixture he had seen for scalloping a fingerboard, it got the wheels a spinning. This is a bit different than the one I outlined in a post not long ago. It isn't as versatile, but it should do exactly what I need it to do with ease.
I will keep you updated as I move forward with this and put it to use. John

I wasn't able to work on it Friday due to a service call. I worked on it today and got it to a point were I could make it go through the motions...........and that is when I realize it can not be used to cut a compound/conical radius! ARG!!!! It will work just fine for cutting a single radius, but that is not what I want.
So I am going to make the other design. It is essentially an upside down pendulum. The carriage swings on two heim joints. This will allow it to swing in a different arc at each end, which the other design would not allow. I have just about all the materials I need except for enough plywood.
I am a bit bummed about this, but not to bad. It is very rare that something I design and build dos not work as intended. Some time failures give new incite and spawn new creativity. I hope this is one of those times.
Thanks for checking it out. I will keep you updated on the next Radius Machine build. Cheers, John

Damn, well its only mach 1. Mach 2 will be better,
