Nice..this could come in handy for me as well...got any pics of your plating setup?
I will, once it's setup and ready to go.
A little bit of downer news today.
The machinist didn't have a bore-bar small enough to do a 2.5" cylinder...
I talked to him for about an hour about other steps to take, and how to do this... he said, because I'm removing less than .5 of a mm on once cylinder, and less than .2 of a mm on the other, that a hone-block with coarse stones will be fine.
The steps he gave me were to:
1- Take initial measurements of the bore.
2- Fit the piston (if possible) and use a feeler gage to get a starting point.
3- Mic the hone so that it's square top to bottom (80 grit stones).
4- Use lots of cutting oil, and don't exceed 600rpm on the tool.
5- Hone a small section of the bottom of the cylinder to gage how fast it will cut under medium pressure.
6- Hone the cylinder top to bottom, not allowing the stones to come out of either end.
7- Stop frequently, clean the bore, re-measure.
8- Once you're close to spec, swap out to finer grit stones (320), re-square the hone.
9- Medium pressure, full strokes for a few seconds.
10- Final pass needs to be slow speed, fast-pulls, dry, medium pressure to cut in the 45 degree hone.
Should be a fun time.
