I have to grind the valves in on the Cub after fitting new guides and cutting the seats.
Last time I did this it was painful; twisting the suction cup tool backwards and forwards with my poor old hands (I suffer from arthritis)
I've heard of people using drills for this but I was always taught that backwards and forwards gave a better result.

So;
Took the suction cups off the stick and rounded over one end.
Turned up a wooden block with a dimple in to accept the rounded off end of the stick.
Made a simple bow with a bit of dowel and string.
I can now hold the valve down on the seat and saw back and forth with the bow.
Works a treat and doesn't hurt the hands.

Nice one Pete, Similar to creating fire without matches.. Scouting stuff..

Good example of problem and solution.. I also don't like the drill method as too easy to to go off square or over do it..

Plus i was taught to lift the valve and turn through 90 degrees every so often and oil the stem...

I hat sounds like a great low-tec solution Pete.

Apologies for predictive text.Sometimes I think an enigma machine would be MRE straightforward.

Grr!

That's a great tip! I wish I'd known it before I found one of those Eezilap tools at a local car boot for 50p! REgards, Mark

A rechargeable screw driver with a forward reverse switch seems a possibility to take the "grind" out of the job.
