Hi brianw
the QCTP is Multifix from PeWe tools in Germany after the hassle of keeping to change tool bit and having to centre every time it makes life so much easier I wouldn’t be without it now , I had to make a couple of bits to mount it and a riser plate with my Pultra being 70mm centre height, I had a Derbyshire Magnus before but this Pultra is so much better.
I am in the process of making a milling attachment for it at the moment because I can’t find a genuine one.
