Flutes are cool little grooves that run parallel to a turned object's long axis. Lots of people do em by hand, or have specialized machines/jigs to help them do them.

I made a quick jig to run flutes along some cool little muddlers I had turned. 

Step 1: Build the Sliding Base

The lathe at techshop has a handy gap that runs along its bed for the tool rest to slide along. I used this gap to put a guide on and keep my jig from tipping over. 

One piece of wood, cut exactly the width of the gap (2.5") and 6 inches wide forms the guide. Another piece, slightly larger (3"), goes underneath the bed and keeps the jig from tipping over or sliding out.

The gap was 1.5" deep, so I made another piece 2.5" wide, and slid it in between the two. However, it needed some sanding down to keep the slide flush with the top of the lathe bed. 

Two pieces of threaded rod slid through all three pieces are for tightening your jig down. (with a nut on the backside or glued to the 3 pieces)

This whole slab slides up underneath the lathe bed and fastens to your jig
It is, the shopbot just didnt cut all the way through and i had to chisel out a small fragment hanging on. The picture shows before I went through and cleaned out that slot. <br> <br>Either way, it's still waaayyy more adjustability than I ended up needing anyways, as I always use the router the exact same height as the lathe turning axis.
umm if u look at the slot of thre picture on the left one of the slots isnt like the other
Such a great idea - I dont think ive ever used a lathe as part of a jig before! Smart!
