Weights on the spinner - this is done during a dynamic balance and does not
negate the weights on the sides of the hub. Weights on the hub itself can be
added on the large castellated nuts to static balance the prop and hub
regardless of whether there is a spinner on the airplane.

If you have a spinner, its put on the spinner back plate.

If truly original, they are titanium. They could also be stainless steel.

Subject: Yak-List: exhaust pipe TIG welding
Can anyone help me with what material the exhaust pipes might be on my Yak52
tricycle? They appear to be original Russian pipes, they are NOT magnetic, and
dark brown in color.
Inconel?
SST?
I need to cut the pipe, slide on a new nut, and TIG weld back together. Inconel
618 filler? SST 304/309?
Thank you

Doc,
Actually, tig welding is how you would weld titanium.
Probably not for the average welder.

had this happen to me at a airshow formation flight, turned out to be the prop
governor . Surged at all 70% and higher power settings but was barely noticeable
at lower power settings. i replaced it and my problem went away.

Most of the exhaust I have seen are stainless steel. My one 52 had a engine out
of a Yak 50 and they were titanium my other one was stainless. If you try to
weld titanium with a tig using a ss rod you will blow a hole in it. Out of the
9 planes I fly with only mine was titanium the rest were Stainless. So one
out of 9 and mine had a Yak 50 engine FWF installed according to the Russian Log.

| Subject: | Re: exhaust pipe TIG welding |
I'm lucky enough to have had a brother of a friend that works in a local aerospace
company that had a vacuum chamber that they used to repair my exhaust pipe
segment after it cracked. It had cracked along the top of the segment in the
bend off #9 cylinder. His advice was if a welder had tried to weld it in a regular
shop with out a gas purge they would have blown a hole in it. hence my ill
informed statement.
Thanks for correcting me.
