The past weekend I had planned to do some welding, sanding and cleaning of the chassis. I startet out just fine, but of course after not having the bottle of inert gas replaced on my welding unit in years I ran out of gas on Saturday, so no more welding that weekend..   

The air ducts from the engine compartment was both cracked under the trunk, my guess is that it is due to vibrations over the years. I did get it repaired on one side (before I ran out of inert gas), and I welded in a piece to reduce future vibration movement.

I hope to be done with the welding, sanding and cleaning of the chassis by next weekend, so that I can get started on priming and coating.  At that point my garage will need a thorough clean up from all the dust! before I start the assembling.     

Best regards Frederik

Hello

Thank you, Anders  Grin

I am finally done with the sanding and cleaning of the chassis (for now..), and I have got the areas with raw metal primed.

I should have spend some time wrapping some of my shelfs and other stuff in the garage with plastic.. It is quite the work getting it all clean again  Undecided

I have also startet on coating the engine crank case and brake calipers. The car is orange, so I choose a fluid and heat resistant two component epoxy top coat in Orange for the crank case (like some old Volvos..), but this paint has been very hard to work with, I have applied 3 coats, and it still seems to need a 4 coat  Shocked I have used this paint in red once before 10 year ago, without this issue.. So I was not that keen on getting startet on painting the brake calipers (with the same paint in red). But for some reason it turns out that the red paint is much, much better, it almost gets perfect coverage in first layer. Know I feel like the engine crank case should have been red too, that would have been so much easier, but I am almost done with it, so orange it is.

I have also got my aluminum parts back from glas blasting, and then back from surface treatment. The parts looked great after glas blasting, but of cause this surface is completely open. After surface treatment the parts has become grey, I had been told that the colour would depend on the surface and the quality af the aluminum, it looks all right, but I would have liked it to turn out in a lighter shade. And the surface still seems very open, which is not what I expected.
All in all I was very pleased with the result of the bolts and metal parts, but next time I will not have the aluminum parts surface treated like this, just glass blasted and treated with Alodine.  

Yesterday I recived two brand new gears for my gearbox, the were not cheap to come by, but it is going to be great with these and new synchromesh rings  Cheesy

The colors on the pictures does not seem "true", but you get the idea  Wink

Regards Frederik

Hi Frederik

It's all really looking good. Like REALLY REALLY good!! I like the idea of the orange engine block. In the picture it looks perfect, but knowing you and by this time, I suspect you've already given it it's fourth coat. The red looks good too, though Smiley

Cleaning up is part of the fun, I guess  Roll Eyes

Are the parts in the box blasted and treated in the same way as the differential housing you're showing? It does look quite grey indeed, and perhaps not "open", but certainly porous.

Congrats on your new gears!

Best

Hello

Thank you again, Anders :-)

I have been working some more on the car the last weeks, and it is for most parts going along just fine.

On the bright side I have a little ekstra time on my hands these days  Undecided

I have run into a problem; I knew that glas blasting and surface treatment of the gearbox housing would be a bit of a gamble, because I did not know, if the treatment would remove material. The guy who glas blasted the gearbox housing covered up the inside and bearing seats, but yesterday I was preparing to assemble the gearbox, and after getting the new bearings on the high gear axle, I tried to place the axle in the housing, and it just slided in (which it was not suppose too  Cry )   It seems the surface treatment has removed some surface material, and now the fit is not correct.

As stated I knew it was a gamble, and it is not a big issue, I have two more gearbox housings, but this time I will just give it a good scrub down with paint remover, before assembling it.

Besides from the little ekstra gearbox work things a turning out just fine  Smiley  

I have bought a type of epoxy 2K primer which I have not been using before. It is made for boats and come in a light or regular version. It is from the manufacturer Hempel. The light primer which I bought is in my objective not light at all..  Cheesy  It is like soft-ice, but when thinned down it is surprisingly easy to work with (with a brush), no bubbles, good cover on edges, very nice finish. I don not know about the durability yet, but so far a am very pleased with it! I apply two coats, first one quiet thin, and the second a bit thicker.

Best regards Frederik
