--> Tailwind-List message posted by: "Robert Ardis" <ardis_rb@hotmail.com>
I talked to Bob many times about the plane and observed as he prepared the
wings before bolting them on the fuselage. He told me that the wings were
purchased in California. I understand that they were never opened and
inspected internally because they appeared to be 'well built'-- certainly a
caveat for all homebuilders.

| Subject: | oil/air separator |
Be careful not to route the breather pipe uphill too much. I tried to
route an oil breather pipe to behind the back wheel of an old
motorcycle. The moisture from the combustion products that normally
escape through the breather, condensed in the pipe, ran back into the
crankcase, built up and turned the oil into mayonaise. A bearing on the
bevel drive shaft to the cam broke up, completely spoiling my day.
Mike Mears.

Jim C or any one--What works good for an oil breather/separator.
Mine had that cheap one the ACS sells for 38 bucks and it didn't do
anything. I Built the one that Tony Bingelis shows on page 93 of his
book on engines. Its about 80% better. but still not enough. I even
considered putting 2 of them in . Go from to the other. Any suggestions?

Gordon, I don't use one. Fasten the breather tube outlet so it
dumps on a exhaust pipe. Jim C

There was a message posted on this list or the forum that had photos of front wing
attachment fittings that appeared to be extensions of the main spar carry
through rather than welded on to the fuselage as per plans. Can someone tell
me who posted those? I need to ask just how that was done. Thanks, Jim Berry

After a nice visit in Baraboo today, lunch in Reedsburg and gas in
Winona MN. I took a second look at the sweatshirt I had on only to find
that It was missing the Wausau flying Service logo. I'm thinking that I
picked up the wrong shirt at Jim's hangar. The good news is that it was
clean and it fit very nice. If anyone knows the where abouts of the
Wausau flying Service sweatshirt let me know and we can trade back.

Most of my tailwind was welded together with ER70s-2. I found I was
able to work with it although it required cleaning the tip due to
spatter very often. I could however control it and make a good weld.
Strength is said to be 70,000 PSI. Friday I went to a different welding
shop and found they stocked Linde #7 rods or equivalent, they are said
to be 50,000 PSI. I have to say they flow and handle much nicer with a
torch than the ER70s-2 rods and I am going back to them. What ever
works I guess. Dave Conrad

Dave,
ER 70 rod is not recommended for gas . The ER stands for Electric Rod .
RG -45 that ACS sells is for gas ( RG -rod gas ) I hope this helps . I like
Linde #7 the best .

Earl, I've found that most shops are selling the ER70 for gas welding.
Right or wrong a lot of planes are being welded together with them.
structurally I'm satisfied with the performance but the linde #7 works
much better. Dave Conrad

Dave, I will check the hanger tomorrow. The one you ended up with can't be
one of mine, they are dirty and usually full of paint. Jim
