Firefly Crankshaft issue 4434

[JasonBModerator @jasonb]

In the Text Frank says to put a 60deg chamfer into the open end of the 8.5mm hole but none is shown on the drawing.

He also states a fairly exact 16.2mm for the raised area wher the shaft meets the web, again no dia given on drawing.

Any comments Glenn?

Jason

View on Arrow B shows the 16.2mm Dia

Do you know a supplier that will do a short length of EN8 for the crankshaft

[JasonBModerator @jasonb]

Well spotted that man.

I bought a foot of 30mm from M-machine as it was cheaper than a foot of 1 1/8" but they will probably do you a shorter length if you ask.

I've just got to upload the last few photos and will then add the descriptions to my thread.

Thank you Jason.

I will order some this week.

Mike, if you have not got the HE15 for the conrod yet they also sell that by the inch.

Jason,

I finally looked at that M-Machine link – thanks for pointing me that way.

They have a good range and I've never had problems with them. They don't have full web shopping but I e-mail a list of what I want and ask them to phone for card details once the order is made up, which they do.
