I think a fairly thick old automobile leaf spring under my shed might wake up in the morning to find a bit of its length missing in such a circumstance.  :dremel:

This is the alternative I'm considering after seeing a countersinking cutter on a Chinese tool website..... :dremel:

Thanks for the ideas guys... :thumbup:

John,

You may probably already have considered this but there's one more thing to bear in mind - If you are going to use the tool either hand driven or via a power tool rather than in a milling or drilling machine you need to set a stop (possibly on the shaft which goes through the valve guide) so that it not only limits the depth of cut but, particularly when using a single insert cutter, to prevent you ending up with a spiral valve seat with a step where the cutter stops.

Cheers.

Phil.
