Canadair CL70 CFR 58-91588

[Robin Craig]

So, not much activity over the winter so far, the corn harvest dragged on and thankfully we did not endure DON issues as those in SW Ontario did. I have others in parts foreign looking for action on their stuff as well, must get on that again.

The engine donated by Paul Singleton, while not moving has some progress in store, I have struck a deal between a great friend, who while absent from these pages is known to many, Nick Tilgner has agreed to rebuild the engine in a complex horse trade deal that will see him get something in exchange apart from money. We will both win. He is quite a VW fan and has done and is doing another VW engine for himself currently. I like the idea that it keeps things with the circle of friends. More on that elsewhere on this forum.

The tires have truly been a stumbling block for this project, both their availability period, the colour of them, and the cost and the money to fund that.

I went straight from corn harvest to my winter side job of snow plowing on nights and as many will realise, it has been a good winter for those of us who do that and don't announce airshows.

I have had a bunch of crazy quotes for tyres with the wrong tread pattern and the wrong colour, grey being available in droves it seems.

Finally my local KAL tire shop unexpectedly blew all the others out of the water by a large percentage. Initially they only had stock of 10 in their system but now have scared up the other 10 and I expect them to arrive in about a week with the tubes. They are a 10 ply rating which gave them concern but when I explained they are going on a split rim they said I should have no problems.

It seems these tires are used in the mining industry and hence the ply rating, I am thinking I don't need a spare but the voice in my head says no.

Lastly, while I had considered chemical stripping, another local new resource appeared at the metal supply shop this week and I got a favourable quote that makes it silly not to engage on.

I am going to start with the rear car tub and see what we can get done on that, and then feed them the front car engine cover and the front car later as money is around.

I will get the chassis frame jig back down to the shop in the next couple of weeks and finish that up and then get going on cutting metal.

So, all in all a good outlook from here to spring. There is a reasonable prospect that the rear car could get back together by this summer and make it out to a show perhaps.

While our garage is still not finished it did lurch forward with the roof trusses going on and getting strapped.

more later.

A bit of movement.

I now have all 20 tires and tubes on hand and in black no less, very happy.

The source of the small sidelights at the front and the rear single red light has I think been solved, they were a very popular GMC and allied brand product used in the late 1940s and quite readily available in both original and repro format.

The rear car body was dropped off for media blasting recently, I have decided against stripping it myself, a better job can be done faster by others. I hope to pick it up this coming weekend.

My mate Nick Tilgner has delved into the original engine and the one Paul Singleton supplied.

He says they are different engines despite appearance. The original one has
lots of surface rust under the valve covers , and its clear from the spark plug removal, that water has entered the top ends. The crank case looks pretty good so far.

What he may do is use the cylinders and heads from the donor motor to rebuild the original engine. He will make that decision based on condition as he goes deeper.

The rear car came back yesterday, nearly all the material gone, the damaged areas highlighted now they out in the open.

I am quite happy with the work done by Last Chance Auto in Yarker, I was very hesitant at leaving it but I am quite happy with the result.

I brought the car over to my neighbour a few houses over, as he is rebuilding a plane in his shop and is very helpful and talented. We looked at the damaged sections and he came up with a much better way to remove the damaged pieces and he will shear me up some material for replacements. He also gave me a method for forming the rolled edge after the holes are cut.

I have an offer from a mate to HVLP paint it, so I will get the damaged pieces out next.

All good.

I have plotted and schemed on most of this project and either found solutions or found money to pay for solutions. However I am stumped with the data plate removed from the rear car.

It is a typical plate with likely silk screened areas and stamped in data in the appropriate places. Regrettably it has some rather clumsy and thick paint that has been splodged on top.

I have tried pushing it off with my finger nail, some success but not much. I put the plate in the freezer to make the paint more brittle but it didn't do much. I am reluctant to take any kind of tool to it, even though the slodges are thick and should just spall and fly if enough sideways pressure is applied.

Does anyone have any earthly clue as to how to clean it without damage? It is the part that is most impossible to replace.

My partner Jan found this page from Popular Science published in 1959 that is wonderful if you enlarge it. Jan is also a wonderfully tolerant lady on top of her research skills!

Re. post 81, try brake fluid. Do a test on a area (like what would be covered by a screw head) first to see if it is safe at lifting the paint and not the silk screened art.

Futher to what James has suggested.... Get a similar plate and try a heat gun.

Patiently....very patiently

I have a bowl of dot3 brake fluid which I use at work for that purpose. I put the whole data plate in the fluid and let it sit overnight. The brake fluid doesn't seem to effect whatever the ink is they use on the data plates.

Afterword, I lightly scrub the plate with 0000 steel wool to bring up the shine of the aluminum, then a coat of wax to retain the luster.

Oh my goodness Rob, I don't know if I would be able to sleep doing what you suggest, I will have to think about that for a while. All great suggestions from you all by the way. Fear is disabling in its own right.

Hi Robin,
I read somewhere about putting the data plate in a slow cooker with water and leaving it overnight to loosen the paint. I haven’t tried it myself, but at least you wouldn’t be using any harsh chemicals. I don’t know if the hot water would damage the silk screening though.

I just did all the data plates (and there were a lot of them) from the M62 wrecker at work in the last few months. Some were original to the vehicle, while some were added later (heater data plates). None suffered whatsoever from the brake fluid.


If overnight scares you, then try for just an hour. Or grab a data plate of something you don't worry about like a heater or an Iltis and give the brake fluid a test run. I think you will be happy.
