Dang it man! I keep seeing what looks like a AA battery above and to the left of your flap disc in these pictures. At first glance, I keep thinking that it's a hand gun bullet! LOL


I think what your looking for might be in this drawer.

When at the hardwear store looking for a better flap disk and found this to try.

It dose leave a better cut but even after blocking finding low spots made from that last flap disk.

So back to chasing a white rabbit.

I even went to marking the low spots so I dont hit them.

Even more hours later I starting to get mad and strated to get even more aggressive.

I have even been trying some weight on the tile when blocking.

At the end of todays quest, I am still left with a low spot in the fire ring.

Well

Either keep at it.

Or

Find an automotive machine shop with a head grinder. Most shops will have a head miller and won't do IDI's because of the inconnel precups. A shop with a grinder won't have an issue with that.

It might be possible to go to a regular machine shop with a big enough surface grinder and see if they'll give it a go.

Path has been set, so need to keep at it till done. The milk is already spilt, so cant got back and choose another path. Could had tryed to borrow the money to get it done instead of wasting oil over the given time that has past, but is now that I see the folly in my decision. So Im just going to grumble about it and hope I learned my lession, hopefully I chose a better path better next time.

Played around with it some yesterday trying to get a even cut.


You must be registered for see images attach




Was still not really getting anywhere so got agressive and took the flap disk to areas inside the fire ring to make a low area, along with cutting hard - on the cups with the sanding disk.

Then back to alternating between blocking and sanding with the grinder.

Today was mostly blocking since for the most part got a full cut.

Some hours latter found that yes its true end to end, but between intake and exhast its a bit happy. So went to running the block end to end.

After some hours some progress was made but when I got to this point it slowed back down

So took the snading disk to the cups and added waight, this did not get me very far and after a hour gave up for the day. This is turning into a wast of time to even try anymore, dont thing can do any better without making a mess of it. So going to the block to see if better progress can be made on that deck. Will have to think about it but think the only choice is to send the heads to get done.

Some times depending on the metal alloy you need to use a slow speed grinder ( <500 rpm) and more pressure to prevent localized work hardening of the metal surface. I found this out when I had to hand grind a titanium shim for a aircraft part I was installing years ago when I used to work in the aircraft industry. When I first started out I used a 3000 rpm air die grinder with 80 grit disks and the titanium would very quickly harden up and stop grinding no matter how much pressure I put on the grinder. So I went to the tool crib and got a slow speed 500 rpm drill motor and started grinding with it and the titanium would not work harden. It was slow going but we got the work done. That was how we did the job until the company installed a new 5-axis CNC mill that could machine the shims properly.

Interesting thought, I am thinking that a 10 to 12 in wide belt sander would be nice right now.

I may be wrong here (if I am, some one please correct me), but since it appears that all of your low places are within the fire rings. If they are, then I wouldn't worry about them since the head gasket doesn't seal here anyway.

If so I would be happy but running the block from exhast to intake side made a low accros the valve line. As it is with a straight edge the thinnest feeler gauge barly fits under it at a cross, between intake and exhaust side shows slightly more wiggle room. From end to end tho its straght, so no issue there. I drew a green line across the area the low can be found and red dot is another Im worred about.

Took the 80 grit disk and went at a few spot that I dont think could mess up, tryed to stay away from the ports so dont round them off.

Tryed it twice and this is what I got after a short time blocking both times. Seems more like it just polished and not much in the way of scratching the surface.

I don't know what the spec is without looking it up. .005 sounds like quite a bit to me. .003 may work, but again, I'm not sure on that one.

Ended up back at that ma and pa store to get a hose made, so picked up a lot of cheap paper.

Since the intake side rail is a low, went with block like this pulling end to end. I used a large waight today in an attempt to make a cut.

Some hours later with many, many, many brakes. I got the last lows to this point.

-red dot is almost mia
-intake rail is mostly down to .003
-right and center are less than .003 except these points that are .003

The amount of pressure that was exerted, I think was bowing the tile because I got a low here now or something was up with the paper. It seems the lows are moving around on me.
