Default 4th Axis

I must say this looks like it would have potential. I could imagine it would be easier to make things like gun stocks etc , as instead of turning around and indexing the part ,the axis just turns it .
Kinda neat .

They show it around 2:35


I donít always insulate , but when I do .
Ok ,I never insulate

Rigidity can be an issue with things like gun stocks on a rotary axis. Sometimes fixtures and multiple operations are a better choice.

When I built our machine I allowed space in the enclosure for the extra driver for a rotary axis, thinking I would add it within the first year. That didn't happen but I still want one. I think it would be better for cutting guitar necks if the neck blank could be rotated. Oh, well, one day maybe...

Again, rigidity can be an issue. I have a friend that has a business making acoustic necks, and they are all done on fixtures.

Does he have a website or YouTube channel, Gerry? I'd like to see what he does unless it's proprietary.

It really depends on the design of the item to be cut. if the intricate design goes completely around the item then the only way to make it is on a rotary axis or true 5 axis machine. If the detail wraps from the side and over the top or bottom then the rotary axis is the best way to go for the hobbyist. If the intricate detail is all on the sides of the object like a wildlife scene on the side of a gunstock then it can be done as a 2 sided project. You can also do a 4 sided project if there are separate top and side elements but it can be problematic if the same design element wraps around.
