Facing the valves and grinding valve seats

[Jim-gsjo]

As far as valve seat grinders go, Hall-Toledo is hard to beat. I used them when I first got started in the business, and still use them occasionally today. The Hall-Toledo model EJ (like the one you use) is great for working on seats that are not perfectly level. They were originally designed to work on inline and V configured engines with the engine sitting in the chassis. If you can find a reprint of the original manual, it has a reference to adjusting the handle's angle and tension to get the best results on different V-8 and V-12 engines. For work that is easily leveled on the bench, I like my Hall-Toledo model VIP the best. The motor is inline with the pilot and easily grinds seats to half a thou' concentricity. A little over twenty years ago I bought a new Serdi, so my Hall-Toledo grinders don't get used very often. They still come in handy for working on things that don't fit the Serdi easily, like Flatheads and IOE's. (Intake Over Exhaust)
It's cool to see that you also use the same model KW valve refacer as I do. Thanks for taking the time to post this video. Many people don't know what is involved in this kind of work. Maybe some youngsters will get interested enough to pursue this as a career.

these Hall Toledo seat grinding machine are very good ones, the only drawback I see is that they hang on the pilot so it is very easy to produce an excentric seat.
very good video.

Where were you 2 years ago when I went looking for information to grind in my first valve seats?! I actually ended up making a video on it, too, since there wasn't anything out there. Nice video and very cool orbiting seat grinder, never seen or heard of that before.

Good video, but since the stones wear, I would recommend showing how to dress the stones.

Hi Randy, Very interesting process. Is what you did to the valve seats normal. I.E 3 angles or is it a Special for that engine ? I thought that car engines were just 1 angle, as I have watched videos of new seats being fitted and recut with a carbide cutter. Perhaps you should also cover up your toolboxes when doing this, I could see the dust going everywhere. Perhaps too if you get a chance with the next one, you could show what the grinding stones looked like and how you dress them to to get the angles flat. Did not see you number the valves either so they go back in the same hole you lapped them in. Thanks for showing us. Regards from Australia.
