Sounds like you had a bad day, yesterday. We all have them and throw things against the wall and quit for a day or two..But I have to believe that the exciting project and work that is being accomplished with you and Achim, will fire you up again,as soon as you get over those "Blues." I almost feel guilty for not answering you sooner-but you have to remember that you only posted a request for radiator info only yesterday.. I was involved with frustrating paperwork and trips back and forth to my accountant for tax work for the past three days. Probably the LAST thing I WANTED to do-but these unpleasant things must be attended to.
I've sent you a private email with contact information for my best three potential sources for the radiator information that you seek. And that is not even including whatever Dan-San might come up with (also some potential, there). Hope Achim's next progress report, or finsihed part or system re-invigorates your enthusiasm. Don't be too hard on us lazy forumites..
Wullfo; I was just thinking about the contacts that I suggested in my off-line email to you. NONE of those people EVER read this forum and NONE of those people use the Internet or email or computers.
Pretty amazing.. But they have spent decades building and reseaching D. VIIs and other WWI aircraft. When you are dealing or interested in history, most people don't realize that the field is filled with a lot of old-timers who prefer to work and produce and research and build on their own efforts of past decades rather than seek info on the Internet or do emails. Even the editor of WWI AERO magazine NEVER reads this forum & never emails etc. I'd say that half of the people I do business with, trade, with, correspond with NEVER email or use the Internet. Of those, most are set in their old ways of doing things (which has been very successful and fulfilling to them) and some are intimidated by the assumed complexities of computer use and usefullness.
I remember for MANY many years telling customers who bought my instruments and parts-and were building replicas-"How can you be in such a complex project and NOT subscribe to WWI AERO magazine with all the contact information and sources and research available there?" STILL probably half of them preferred to go it alone and not even LOOK at that great source of help. Today I STILL ask them that question, but I ALSO ask, "Hopw can you not get a computer and see what is readily available to help you on the Internet or theaerodrome.com forum?" But still there are MANY of the best builders who don't wan't to get caught up in the distractions, and feel they have enough info and sources to remain singularly focused on their own project, in a world of their own and very happy and satisfied with that..
35-40 years ago, I wondered the same thing when trying to contact people who could only be reached by mail! How could people do without a telephone!!!!??? But some of them had INCREDIBLE accomplishments and collections.. Don't be soured by lack of immediate Internet response. I used to be calm about Intenational correspondence to include some needed photos which would take a week to get back the photo-a week to email to Europe- a week or more to get a response- a week to make my reply etc. (cost probaly ten dollars or so with film & psotage)
Now I take a digital photo, get it to a party in Europe (or the other side of the world where it isn't even the same calendar day!) in seconds (sometimes)-get a reply in seconds-reply again all within a minute or two. at a couple of pennies cost! Perspective, my good friend..
