Looks like we are missing a part drawing.
I couldn't find anything that holds the Piston Rod to the Beam Links. On page 17 zone A2, "Cylinder Rod End Bushing " is shown that would make that connection, but can't find a drawing for it. The "Cross Head Link Bushing" (actually our item #33) (note that names are different on page 17 vs the rest of the pages) is what we need except shorter. I would suggest that each builder make their own. Same as #33 except instead the length of .808", it would have a length of .510" or more then face off the excess so that there is just a little overhang when assembling.

Comments?

Worked for about 3 1/2 hours getting the rockers cut but when I was done I notice something was wrong. Something must have changed when I flipped them over to cut the pockets. Looks like I have some new parts to make.

Dave,

Could you enlarge the pockets a bit to even the sides out? Might be worth a shot to save remaking them (it is just a cosmetic feature you're dealing with)

I was thinking about trying to open up the pocket. I have 2 extra pieces to try.

I am using the smooth stepper in the box to allow the use of the laptop along with mach3. Ron ginger could answer questions on the control box. I went to the cnc build in Ann Arbor mi to build the mill

I think I saved the Rockers. I opened up the pockets by .010 and recut them and looks much better.

I also got the bases mostly done with a little cleanup on them.

Dave:

Nice save! If you had not mentioned it, none of use would have noticed....
bases look good, too.

I'm still waiting for material to arrive. Patiently. Really, patiently.

Dave,

You're too keen - all done already! What are you going to do for the next 3 months while the rest of us get our butts in gear?

I need to go get more material. I've had a change in plans on how I'm making the eccentric strap and need some more material. Thank goodness its only steel and is about as cheap as it gets....the other stuff I bought will just go into the pile of stock material for use whenever. I didn't have any known good steel anyways.

Plus an excuse to visit the metal store is always nice (but costly)!

Mike

I have 70 more parts to do. 30 pins for the rods. 30 center pins and 10 pivot pins. I have to wait on material for them as we'll. I got lucky on the rockers I fixed it the way I should have done it in the first place. Like I said in an earlier post in still on the uphill on the learning curve of cnc.
