Dennis Savarese" Subject: Re: Yak-List: V530 prop balance 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.

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?

Probably not for the average welder. http://www.millerwelds.com/resources/articles/TIG-gtaw-titanium-welding Laterrrrrr John Fischer On 5/4/2013 9:01 PM, Roger Kemp M.D. wrote: > Titanium.

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.

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.
