I did some playing around today on the DIY lathe. It was all about what was required to do a particular operation and get it done quickly. In all it took about 6 hours. Just bare not even scuffed for finish. You can’t do this on a router crafter, Legacy or a Laguna but You can do it on your lathe at home! Takes some time and some thinking.
I took about an hour to cut the template and turn the basic shape.
Took an hour to get the tooling change and get the offset on the router and template. Then I cut the first two sets of grooves. The rod rides against a pillar to keep the cutter 90 deg to the surface.
I needed a small diameter so I used a piece of pipe on the tail stock center for tracking the cable. I drilled a hole through the pipe so the cable would bite and not slip. I disconnected the longitudinal feed wheel so the longitudinal feed would move with the least amount of effort and turned the work this advanced the longitudinal feed at a set rate like threading on a metal lathe. I had both of the cables running side by side so when I wanted to change the direction of the spiral I just hooked up on the other cable. ! hour there
For these it was back to hand cranking.
Everything in the bag of tricks for today! Swivel router mount. Perpendicularity post. Template and follower.
