I have a Bridgeport, and I like this system. Only thing is, I have about 60 original KOWA valve seat cutters and the pilots/reamers/guide installation tools. They weren't cheap nor easy to find and I only work on Honda motorcycle ATV/ATC heads anyway. I may sell these cutters someday and switch to a more adjustable system like this. You eed this system for the new motors with bucket shimmed valves and harder valve seat material. Great video showing how this all works!
I was a machinist / model maker for 40 years. I'm very impressed with your careful set up. Nice job! My only other comment is please, please wear safety glasses, you are done if you damage your eyes.
Well that brought back memories. 25 years retired from working in a famous British bike shop in London where I would do the valve work on triumphs. Back then just about everything was available engine wise but we made a lot of bodywork parts in house. PS hated triumph heads as the seats quickly recessed too far after a couple of valve guide changes.
@@stuntr1 considering that I don’t have to use lapping compound to check the contact or lap the valves, I’m going to assume it’s less than .001”. Angle plate came from eBay.
@@classicbritishspares Just have found that sometimes you can end up with a pretty sunken seat by the time you get all trued up and all three angles in there.
@@drrjim exactly why I don’t do three angles. Most of the time I cut a 45, and I do the bottom angle. Other than that I leave it. Not gonna make much of a difference anyways. If the valve seat is concentric to the guide, and insert, it’s better and then you can do a three angle
I've spent well over 1000$ on KOWA cutters, but I take on sidework so I don't worry about the initial investment. Of course it's hard for the average guy, but even if you had your own head to do, you are looking at 600$ worth of cutters. Or, you can pay people to do it for you, and I hate giving my money to other people.

How is it this young guy has all this OLD Dude knowledge.....keep up the good work

Outstanding! Lots I can replicate here.
I love these videos. Keep them coming!!!
Thanks!
Thanks for the great demonstration.
Thank you very much for offering great tools!

Well done young man...
Thank you
Have you ever used a runout gauge and see what u get ? Interested in your runout figures. Also, where did you get your adjustable angle plate?

Nice job
Can you itemize all the components you used of the Goodson "3D Fast Cut" system ?
Maybe in a next video, thanks
Great work, nice setup. Safety glasses?
Thanks - no glasses needed
Nice job. Just curious how you handle that big hammered wide 45 on the exh?
Cut the bottom angle, and cut the top angle. Not really necessary

@@classicbritishspares Yes, often they are not concentric to the guide. Thanks for your communication. And again, good job !
@@drrjim thank you !
I wish you weren't 1000 of miles away, I've got a 650 head which needs work!
If you would like us to perform a valve job, send us photos of your cylinder head to sales@classicbritishspares.com
Why not use 3 angle cutter and cut in one process? This is a real question not confronting you on your process.
Not enough seat to do it to be honest. Enough for a 45 and a bottom angle
using tools nobody but you will ever have, kinda makes it abit out of touch.
Not really, most of the tools I have many folks have in the industry or as a home machinist. Thanks for watching
