Title: ED Bee Con Rod
Post by: Allen Smithee on July 30, 2018, 04:02:32 PM
A friend of mine has come by an ED Bee which he'd quite like to use in a suitable radio-assist vintage model. The engine seems to be in pretty good nick except that it has a broken con rod. My normal sources have drawn a blank on this (including Alan Greenfield), so I wondered if anyone here had a spare one they don't need? The engine is a mk2 Bee, so it has the Aluminium rod rather than the case-hardened steel one. As far as I know the ED Cadet rod was probably the same as well. SO if anyone has one could they possibly get in touch?

Failing that - given that he wants to use it as a runner rather than a museum piece, and a basic rod for a small, low-power diesel isn't exactly the most complex job in the world, does anyone have a drawing or even just the principle dimensions? I guess I could probably get by with the big/little-end bore sizes, the distance between centres and the thickness...

TIA,

AS

Is the broken con rod mangled beyond taking measurements from it?

No, but half of it is missing!

Ask on Adrian's blog http://adriansmodelaeroengines.com/wordpress/ to see if someone knows the correct length and then it should be easy enough to make as it is only a simple steel rod

I had the notion to ask Ron Chernich before he died about collecting such data for future repairs .... maybe Adrian would be interested.

I do have a number of in-complete production engines where pistons an rods are missing, so beside rod length, it would be nice to have piston height and pin position (distance from crown). I have made an excel file on all my engines and do fill in as I get info - or disassemble one of the complete ones.

- But I do not have any info on the ED Bee - sorry.

The original was forged aluminium, but I suspect one made from bar-stock dural will be adequate. But yes, it's not a hard thing to make.

Many thanks to Eric, and others for the help. My friend is now happy, and sent me this to prove it:
