Hi Piet,

Check out the attachment on the email I sent you...I can't link it here

Page 385 of the book. "A Maunual of Marine Engineering" by Seaton
Charles Griffin and Company

The air pump volume of an engine driven air pump should be LP volume /21 to a LP Volume /25

I found another reference by Seaton and it gives a similar ratio of .04 x LP volume or LP volume /25 (Page 159 of the book linked below)

http://www.archive.org/stream/apocketbookmari00roungoog#page/n185/mode/1up

This is consistent with designs by Whitney as published in Mitchels "Steamboats"

It's also consistent with my pump which comes in around LP Volume /19...I am betting my pump is not as efficient and that the air leaks are larger than full size practice.......time will tell

Again....thanks, Dave and Barts.
But my engine is an compound 1,5+3X3,5.
Iám reading everywere that its better to run an compound whit an airpomp. So, if I get you guys, try it firts without an pomp?
I was thinking about an Jabsco pomp, the one whit the rubber impellor, connected to the propellorshaft. But it is only working in one direction. So that can be an probleme.

Piet,

Sent an email, but apparently it bounced, acording to my security software.

Did you get the google book via email from me?

For big file transfer, I just upload them to wikiupload, then send the recipient a link to it. They allow files up to a few gig seem to recall.

Hi Detroit,
I went to that site and my spyware went nuts....did not like it and it wanted me to log in with an address other than my country......

Seems like a scam I am afraid.......Piet....I'll have to try something else.

This site?

http://www.wikiupload.com/

I have a McAfee suite up to date and run malwarebytes plus Superantispyware, and I go to it, no trouble at all.

You must have went to some mirror site??

Some of this protection software is getting bad about being too careful with false positives. That is a very popular and trusted site.

Dave, That is really weird, I go to it no trouble at all, and no I don't even live in Zimbabwe Smile

Some of the sites in the UK posted on the forum here I can't get to as well. Malwarebytes just stops the browser???
