You should attempt to mechanically trap the sleeve in the bore. You can leave a shoulder at the bottom of the bore - press the sleeve into the bore - and then machine the top of the sleeve flush with the block.
or you can mill/bore a counter bore at the top of the block - turn the sleeve to leave a shoulder at the top outside of the sleeve - press the sleeve into the bore and machine the top of the sleeve flush. You will then have the sleeve trapped between the block and the head. I would bore the block with boring bar and leave a shoulder at the bottom of the bore. just my thoughts Stuart On Tue, Aug 1, 2017 at 2:43 PM, Ed <ate...@mwt.net> wrote: > > Oops. >> Here is my website: >> >>> http://wallacecompany.com/machine_shop/index.html >>> >> >> The likely mill would be the Shizuoka: >> >>> http://www.wallacecompany.com/machine_shop/Shizuoka/ >>> >> >> My Zubal might swing it, but it's not CNC yet: >> >>> http://www.wallacecompany.com/cnc_lathe/ >>> >> >> >> A lathe is the most stable, a mill is easier to set up.
