How to grind tappet heads.

Photo says it all.

I do have a small high speed drilling machine, Dermel equivalent and angle grinders.

Suggestions please, as all eight need doing.

The Warden kit is mocking me, so time to pull finger.

Geoff - Overhaul the SU carb next.

I would hold them in the lathe and use your dremel in the toolpost to gently remove the dimple.

Have you checked your cam followers they are a bit more of an interesting challenge to re-grind to the correct radius.

Collet chuck on the lathe and turn with carbide then polish up. Or send them to me and I can grind them.

The tappet screws can be done with a tipped tool, for the cam followers I made this, goes in place of the rest.

This should show it better

Thanks for the responses.

Cam followers appear fine, BUT will check for uneven contact with trial assembly.

Thanks for the offer Chris, and I will take you up on it if my grinding proves less than satisfactory, after I put the camshaft, block and valve gear back together and rotate the cam to check followers/lobe contact.

Grinding done, using the high speed drilling machine as per photo, and in a typical Heath Robinson fashion by sliding the vice around the table.

A quick lick on X-fine diamond card and result as seen.

Easier than I expected.

Geoff - SU carb, that will replace the original, stripped for cleaning and refurbishing.
