    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Ordered me some Neway cutters to do my own valve jobs today

My engine is apart and I'm reading all this Greek ! :confused:

What have I gotten into here ??
Where is that 'Sky is Falling' emoticon......:D:D:D

Intakes are mostly done. I need to exchange the 75 degree cutter I bought for a smaller one so that's holding me up some.

Neway sells different blades for cutting "hard seats", which the exhaust side Suzuki seats definetly are. Wish I knew this going in but the regular cutters are getting the job done, it just takes quite a bit of pressure to make the cuts.

Narrowing the seat is the challange, particularly when making the top 15 degree cut since there is a lot of material to remove because the seat is so wide on top. The photos below show basically a finished intake seat, but the exhausts haven't been narrowed yet. Photos also show some of the corrosion damage that occured on this head. I don't think the pitting will cause any problems...hopefully.

Good fun.:)

Looking good Ed. Fun stuff, huh?!! I did my first valve jobs with grinding stones before moving on to Neway stuff back when I was learning. The time involved with 16 vlaves versus 8 is what made me go Serdi. Ray.
 
Hey Ed,

That does look like fun. Thanks for the lesson. Keep 'em coming.


Thank you for your indulgence,

BassCliff

Thanks Ray.:) Yup, takes a LOT of time using these hand-turn cutters. If the seats were softer it would be much easier.

For the last (confirmation) cut on the 45, I colored the seat with a sharpie and then took the cutter and turn it lightly with my fingers, so there is no side load at all - the cutter just kisses the surface and skims off the sharpie mark.:D

The other cutter should be here Monday or Tuesday so I can finish up then. After that I'm going to get this thing surfaced and call it done.:-\\\
 
Ed, go buy a can of Dykem (machinists dye). Either blue or red. It will make it much easier & quicker for you than a Sharpie. Ray.

I have some but it's gummy, sharpie works better. Maybe it's too old - must be 10-15 years old.:eek:
