Valve seat cutting

[Amblejo1]

Many thanks for posting the drawing of the seat cutting tool George.

That will help me a great deal.

It will probably take me much longer to make the tool than it will to cut the valve seats, but there is great satisfaction to gained from doing a job well isn't there?

I just have to reply to this. I haven't made George's valve seating tool but I do plan to, using Dave's 5 tooth design. Brian I have to say this forum would be much different today had you taken up tap dancing. I do have a friend who can heat treat stuff for me but it has to be S7 to not send up red flags.

Here's mine, a simple guided D bit (with an odd number of cutters - 1  )





Stay well,

Here is a tool I made for re-cutting the valve seats on my Austin Seven engine, it based on an R8 collet blank.
The actual cutter is made from a broken 1/4" screwed shank end mill.



I also opened out the throats with a boring head to get better gas flow.
