Doyle Rotary: Machining the Cylinder Retainers

This is a really great picture.

With your permission, I'd blow this up and hang it on the wall in my office. I looked at them all.

Following with interest - thanks - keep 'em coming.

The following picture shows how we plan to hold each cylinder sleeve for honing.

The retainer on top of the sleeve is just like the parts being fabricated on the machine right now. The retainer on the bottom has the two handles to hold while honing.

The reason that we have to rig the sleeves up like this for honing is that we need to simulate the compression forces that the sleeves will be under when installed. The handle retainer simulates the cylinder block that the sleeve will eventually bottom-out in and the retainer on top is attached with bolts torqued the same as they will be in the engine.

So after we hone the sleeve in this rig and then torque the sleeve into the block, the sleeve will be perfectly round.

lynlynch: You can definitely print out a large copy of that picture or any others (that pic is actually the background on my phone right now ). A while back we used our plotter to make a blown up image of the wire frame Solidworks model of the crankshaft. It is now hanging in the office at the shop and looks like a cool poster.

JohnDG: We are glad that this is interesting to more than just us . Have you made any progress on bridging the computer to machine gap?
