awsum55 ...... That last picture solves a problem I've been trying to solve for a few years, creating threads.
I used to use these "box threaders" in the past, but when I found out about the Beall Wood Threaders (Now sold by Lee Valley), I was converted. Excluding the router/trimmer required, the set cost quite a few shekels less than a full set of the "box" units. The old "box threaders" were reasonable dyes, and while I considered the Beall just margionally better, they required setup and configuring the router bit depth however, the Beall taps left the others for dead (my opinion)... Beall on top
The issue is the Beall 38.1mm diameter limit... unlimited with 3D, though you have to design yourself... though most 3D software have plugins nowadays... you just have to find one for your hardware/software inventory.
With the Beall I did manage this prototype in wood,
Alternatively you could try your hand at thread chasing... I got one of the tools, but not the nous or patience to learn.
RobsCastle ..... I will stick to shop bought ones though...
Which means you've already go the magnets... 3D printers can be built dirt cheap and with your techo ability, you'd probably earn a few shekels for your effort.
If your first cut is too short... Take the second cut from the longer end... LBD
