'34 engine, grinding valve seats

[Carla]

Well, it turns out that I have to confess myself mistaken on one detail.......it turns out that the old style Halls seat grinder is indeed out of production, but the Hall Toledo company is still in business, and will rebuld them, or sell factory rebuilt units.

I just got off the phone with Andy Boesel of Halls, he told me that he could sell us an 'as new factory rebuilt' eccentric seat grinding rig for $1000. With the necessary pilots, stones, etc., the gross figure for a seat grinding setup suitable for the old Dodge/Ply engines would be around $1400-ish.

I don't think we'll be doing enough of these engines ourselves in near future to justify the investment, but should anyone here be thinking about rebuilding some number of these engines, that Halls seat rig would be an excellent investment. The Halls seat rig is just so much nicer to use than is the Sioux or Kwik Way equipment.

I was doing the valve seats of our '34's engine today, and thought I'd do some photos of the procedure.

(I thought that maybe a few of the newbies here haven't had occasion to do any of this work, so they might be interested in seeing how its done.)

Note that the seat stones are dressed to the 45 deg of the valve, 30 degrees for narrowing the seat from the top, and 60 deg for narrowing the seat from the inside. The idea is that the valve seat itself will be a little less than 1/16" wide, and located in the centre of the working face of the valve. This creates the so-called 'three-angle' valve seat.

(The better way to do this job would be to have one of the old 'Halls' eccentric seat grinders, which can be dressed for actual radiused seats, but those have been out of production for years and years, and are nearly impossible to find in serviceable condition. The 'Sioux' and 'Kwik-Way' hard seat grinding equipment, which are the only ones now available, are set up to dress the seat wheels to any desired angle, but not to a radius, so the 'three angles' are used to create the effective equivalent of a radiused seat.)

After the seats are ground, the valves are numbered, and hand-lapped into their specific seats.

Anyway, here are the photos.....I put them in the ebay photo area of our web-site.

You may need to do a 'cut and paste' for the internet addresses for the photos.
