dalem9 ...

Item number 23 is the Cylinder Rod Packing Gland found on page 13 zone B1.
It's also the Cylinder sub assembly on page 16 zone B3, its mounted oo the Top Cylinder Head item 22.

You should download the Excel sheet... that is where all the Item Numbers, builders and other information.

Chuck,
The con rod big end is designed the same as full sized steam engines of that period.
the rod and keeper were steel and had a 2 part "brass" sandwiched between them.
This design allowed adjusting a worn bearing and would be a nice detail to have on
the model.
I think it best to propose any big changes to the team and see what the consensus is.
Small changes to simplify or embellish parts shouldn't be a problem but it's always
good to communicate. I'm thinking of a 6 spoke flywheel rather than the 8 spoke in
the drawings because the 8 spoke looks too thick and heavy, any comments?

Regards,
Maverick

dalem9 ...

The plans are : (see also thread #72)
http://homemodelenginemachinist.com/...anpdf-125.html

The Excel is here: (see also thread #84)
http://www.homemodelenginemachinist....8-details.xlsx

The spreadsheet has not been updated for assignments, I will update probably tomorrow. However, the item numbers etc are okay.

Chuck and Maverick ... I agree ... need to suggest changes before hand. I would like to keep that detail. However, if you want yours to be changed I don't see why not ... after all it is yours!
Silver solder ... I can do mine and others if necessary.

The flywheels ... 6 spokes will look great. << Edit

I must be missing something here but what gets silver soldered?
Also I was thinking of using stainless for the pistons ( would that be an issue?)

Chris,
Item 27 (Valve Stem) is silver soldered to item 29 (Valve Link Rod)
according to the note on page 14 zone B3 .
But it is not clear to me as to why ... since it is bolted. Maybe for additional mechanical strength.

Additionally there seems to be fit issue with those parts (.087 hole vs .093 pin). Looks like that area needs to be looked into for clarification.

Maybe someone would comment on that.


Instead of Brass for the Piston ... stainless would be the way to go.

Hi guys

sorry for the delay in getting back to you, I've been out of town since Monday.

I'm happy with page 12, leaving page 7 for Chuck.

Chuck, the whole purpose of a team build is not to have this stunning project in the end ( although is a bonus)
It's to challenge yourself ion parts that you can do and the challenge of having 10 guys in different parts of the world build pieces of something and being able to put it all together working. Also the making of new friends.

You will do just fine,
Chris
