Lynx II, hull # 4225

[Peter Duggan]

Alex,

Thanks for another great picture. It certainly looks the part, however the only time I've seen the Ad Hoc welded flat bar storage on the sides were on Dingoes.

Regardless, it's an iconic picture. The struggle with mechanical problems and the challenges faced with the weather were part of the grind that all the troops had to overcome.

I'll share another of my favorites. While it's not a Lynx the look on the troopers faces speaks volumes.

Guys,

Andy fabricated the last of the storage bins for the rear fenders. His usual great work. Now to have them sand blasted and epoxy primed.

Now one of the new front wheel brake cylinders decided to spring a leak, now to find out why. Usual two forward, one back.

Peter, NOS or modern equivalent on the wheel cylinder?

Chris,

I used new replacement parts when I did the brakes. I don't think the parts are the issue. I suspect my workmanship and some sloppy copper washers. I've got the proper sized copper washers coming and I'm hoping that with a good cleanup and assembly that the leak will disappear.

Thanks, Peter

Just keep turning the bolt in tighter and tighter and tighter until it snaps off. Then you know for next time to stop just before that point.

I started a thread way back about copper washers, and in fact on the lynx here at the museum. I went with DOT5 (silicone) brake fluid, and was having a real hard time getting the copper gaskets to seal. There just didn't seem to be an appropriate torque. I think Barry Churcher related that he would not use the new ones, but rather the old ones worked well.

I tired tighter, new washers, mil-spec washers, and even tried to anneal them. In the end, I cheated by applying a thin thin smear of silicone RTV to the copper washers. It worked. But I am not suggesting that to anybody, as it is not an approved method of sealing. And it might only work with DOT5...I cannot say what DOT3 or 4 would do to RTV.

Copper work hardens to the point where it can crack. They should be annealed before use, unless they look fresh. The old washers (in good cond.) will work fine if annealed. (heated up to red hot)

Jordan if you stop at the "easy feeling" and back it off a bit, maybe no one will find out???
