340 damage dilemma

LOL. I don't know what takes you so long. It ain't that hard. And I don't include the hone and surface in the cost of setting a sleeve.Why wouldn't you include them? You perform those operations don't you? I don't know anyone who billed setting sleeves like that. I've never been asked to install a sleeve and not finish hone it to size or leave it sticking out of the deck either.





Don't know how you do it, but I can get the block in the machine and have the first hole in and ready to go in about 10 minutes. If I have a rigid machine and carbide tooling you can cut the bore in one pass. Otherwise it's two cuts. Big deal. Most use a 3/32" wall sleeve which is about .095" to cut. No conventional automotive boring bar or boring mill can take almost .100" in one cut much less two. My Winona Van Norman boring mill cannot cut more than about .025" per pass without issues. This means it takes a total of 5 passes including a light finish pass and it takes 8 1/2" minutes to travel about 5.5"'s. This alone is 42.5 minutes and I haven't squared the bottom or driven in the sleeve or topped the sleeve and then it is two passes to rough bore the sleeve for finish honing. It also takes longer for the first cylinder with the the initial set up.

Square off the bottom and install the sleeve. That's maybe half an hour. Maybe. So my $125.00 is $250.00 an hour. Good for you, I'll send some blocks to you.

Then you repeat. I top all the sleeves at one time and flip the block and do it again.

How you do it, I can't say. Again, it ain't hard.

And of course, you have to finish bore the sleeve(s) and hone them to size and then surface the block. Yes this is factored in to my price--why isn't included in yours?

Again, it ain't hard and it don't take that long. Never said it was hard, just a lengthy operation that requires far more precision than you are leading many to believe.
