Paul was most complementary, saying that it felt like a nice new car, with everything like brakes and steering working well.
The big problem that we had over the weekend was that the hybrid dry sump system we had fitted would take all the oil and not return it when the motor was running above 5500rpm. Anything less than that and it worked fine with no problems.
The other issue was that it was getting unsettled at the top of the rise of turn 3 and a couple of times Jay lost it when he backed offf on the throttle at that point, and it snapped into oversteer - scaring the crap out of him.
Nothing that can't be sorted, and both he and Paul think that it will develop into a nice beast once we tame it.

Thanks Wal. It was great to see the car there, and I really hope the field of NZ owned Can-Am cars continues to grow.

It is one of the things that he kept with him through all his moves, and he had it at his house at Hervey Bay. It was used in the building of most of his 18 cars.
I was very surprised when I was told that over in the U.K. gas fluxiing is no longer permitted.
I have used the gas flux and nicklel bronze (and Georges torch) on all the components I have had to remake.


Georges first fluxer was made from scrap steel tube with top and botom weled and bolted on ,one tube in nearly to the bottom, out let at the top. this was the norm untill the fm5 early 70s {based on my 6 years at working at the workshop.

It was a vapour flux that came through the acetylene hose. A cast bottle as the third bottle on the set. No need to dip rod into flux powder.

Rick Diehl built PDL Mustang 2 with a fluxing torch made out of an old truck remote mounted oil filter. You put the acetylene in one side and a pipe near to the bottom of the filter body, which was filled with the liquid you bought, mixed it all up as a gas and it came out the other side and burnt with a lovely green flame. I have brazed with one and it's like night and day, you can see the crap being washed away as you are heating the work. Not having to re dip into flux is a big help as well.

Any remote oil filter will do the trick, the acetylene just bubbles through the flux on its way to the torch and you can run the weld continuously. Best to have a dedicated acetylene set with this set up though because the hoses etc become contaminated with the flux and there will always be some residual. Pretty hard on hoses too if I recall correctly.

I cannot add a lot to the gas fluxer info other than agree to what has been posted. I was lucky enough to pick up this commercially made unit second hand in Christchurch several years ago. It has a bypass valve at the top but so much flux remains in the system for such a long time, that yes you really need a dedicated system.
A friend in Auckland made a 'fluxer' that is just a auxilary oil filter unit complete with oil filter cartridge that he 1/3 fills with flux, then passes the gas through the in and out fittings. The filter 'wicks up' enough fluid that the passing gas comes out 'fluxed'. The flux is highly corrosive, and the filter has to be changed often.
When I first went to England in the early 60's 'Gas Fluxing' was the way everybody built their tubular space frame chassis ((in Italy they seemed to electric weld - badly - at that time).
Wishbones - gas fluxed - were then Cadmium plated.
In England last year I was surprised that gas fluxing was not allowed. Cadmium Plating of course was banned many years ago, and I tend toward Nickel nowdays.

Good work Jerry

I texted Walter this morning with birthday greetings. You may be interested to learn your old pal Howden and I took Wal to lunch last Monday down in Invercargill - where the sun shone, as it had since we'd arrived four days earlier!

We were heading off to lunch and dropped in on David Brown. Howden is leaning on the recreation of 'Big Ed' that he and Wal built originally in the mid 60s!
