Reading a drawing - Radius

Was there from the conception of the site and the reason it started as a protest from HMEM. Enough dummy spitting on this site without joining another although there are " a few good men " over there.

"Closed shop" plan section doesn't help the "Helping" theory.

Regards Ian.

I know its bad form to quote from my own earlier reply, but now that the dust has settled on the original purpose of the thread I am still curious about the oil hole drilled through the edge of the part.

Maybe I have misread the drawing but drilling into the edge of a 2mm thick plate seems a bit odd.

There is a bronze bearing that is pressed into the hole which I think is why it is suggested to drill after assembly so the hole goes through both parts.

Agree it does weaken the thin frame though I doubt its under much strain. If the bearing were soldered in that would be stronger.

As the bush is 5mm O/A length with 2mm in the hole & 3mm projecting I think I would be tempted to put the oil hole into just the bearing set back 1.5mm from the edge.

I think I'm right in saying that several of Julius' designs are just that designs on the comp[uter and have not been made, its only when people start to make them that the practicalities come into play.

Ian if you look at Bruce's other thread you will see what the finished engine should look like
