The is the notching tool I made so I can make a clean fish mouth in pipes
The shaft is a sigma strut
slide ( bearing ) from the strut
some bits laying about and machine the V block from bar stock
This uses a bimetal hole saw , can cut up to 100mm pipe .
units fits a stand up drill on slow speed with cuting oil .
