Changing tools and setting up the correct height with a conventional tool post is just a hell of a job. That's why I made this quick change tool post. You can download the drawing as Adobe PDF-file for your own use.
Mr. Ishimura, thanks for the design and making procedure on your website!
Making of the holders.
I machined the dovetail in a 400 mm long bar, then cut it to pieces and finished the holders.
A finished set of holders.
From left to right:
toolholder for threading insert
toolholder for circlip grooving insert
toolholder for lefhand turning
toolholder for right hand turning
toolholder -empty-
toolholder for boring bar
Finished parts for a cut-off toolholder.
The bracket for the height adjustment is already blackened because I made several of those in advance some time ago. The holder itself and the clamping bar still have to be blackened.
See the picture below to get an indication of the cutting tools needed to machine these parts.
These are the cutting tools I needed to machine the parts for the cut-off holder:
45 degree homemade chamfering mill
15 degree end mill
20mm roughing cutter
30mm homemade fly-cutter
60 degree dovetail cutter
2mm t-slot cutter
10mm 4-flute end mill
6mm centering drill
2mm drill
5.5mm drill
4.2mm drill
M5 tap
And this is the fully assembled cut-off holder.
Blackened and with the cut-off blade installed.
