I have a couple of questions on my parts on sheet 7.
1. Connecting rod at A3. The flat piece on the left end is .o62 thick?

2. Con rod bearing shown at A2. Drawing states drill & ream .250 as a pair. Should I do this as one piece and slit after reaming? Same detail, what is the meaning of the symbol between 0.089 and 0.750 on call out for hole for hex head screw?

3. I don't see an overall length for rod clevis at 1B.

Could one of the more experienced folks clarify these for me, please?

Chuck

Chuck,

Glad you asked I just finished making drawings in Solidworks so I should be able to help.

1. If you are referring to Keeper Plate item 11 (zone 1A) then yes .062 or 1/16" will do.

2.That symbol denotes the depth of the hole. In this case all the way through. The .75 is an error. The drilling and reaming needs to be done as a single piece after the slitting. If slitting is not done before ... the hole will not be concentric or the correct diameter.

3.The missing length (left of the .282) is not critical. So what I did is measured it (on the drawing) and scaled it up, I came up with .3 . So the overall length is: .3 + .282 +.125 (radius given from the hole to the edge) = .707 . Note that .707 is not the important dimension the individual ones are with the .3 least important.

Just as a note I found a lot of missing measurements ... and scaling up was the way I got the answer and most were not critical .. kinda left up to the builder.

Except one on the frames ... which I will go into later.


Hope this helps,

Pat H

Dave, I'm not fussy on base color. What ever is easy. I think this engine will look good on what ever you come up with!

I will be good with whatever I get for the base.

I have got one piston and shaft done.
The shaft is on spec .157 +- .003
( my lathe has a few thou taper unfortunately )
The piston I did .490 hope that is ok Dale ?
The oring will be a snug fit into .500 bore
