Is the distance between the axle hole and the peg hole a standard stud
distance?
|
Good question! It “arguably” doesn’t matter as much as some distances
though, unless you plan to mount something between them. In many
applications you just have the main rod and or connecting rod to deal with
and the eccentricity they have is only a factor in considering how much
connecting rod and piston rod throw you’re going to have to deal with.
Still it would be nice to know. Personally I hope it’s rather short.

Well, I know how pointless it would be to “argue” with Lar (grin), but it
would seem silly to not have this be a standard distance.
|
Ya I agree. I was only saying that in the universe of design decisions, some
matter more than others and this one matters less. But Ben’s design does indeed
use a standard distance...

imagine using a Technic cam or 1x3 liftarm on a wheel. (John frantically
searching for FTX reference for displaying LDraw images and not finding

I look for that reference a lot too. I find it this way, via a trick I learned a
while back, maybe it will help you too. The “more” link on the side of the post
box when posting in FTX mode leads you here:
http://www.lugnet.com/publish/ftx/guide/ftx-refcard-600x525.html
delete the html part so all you have left is this: (this is the key thing to
remember):
http://www.lugnet.com/publish/ftx/guide/
and that’s your guide. Midway down the page is the info on inserting LDraw
parts, which takes you here
http://www.lugnet.com/publish/ftx/guide/ldrawparts
so the cam you want is
Hope that helps!
And oh by the way, I got my wish, Ben’s throw IS rather short, just one stud.
Some freight engines have higher eccentricity but I think short throw is a good
compromise.
