Back again with the last post for this evening.

While I was waiting for the epoxy to go off in the cowl mounting holes I thought that I would take a look at the detail level of the Dzus fastners.
The spats have had a coat or two of primer and black paint as they are very susceptible to hangar rash and grass rash at the field.

My fear is that we would lose the Dzus fasteners under the next coat of paint. Shame with all the work that went into the 28 or so that were made.

 

These two are out of the way and have not had a slather of paints put over them. They are still acceptable to my eye.


I reckon that the next coat of primer and black paint will see this one and it fellows nearby vanish.


I  made a mask out of litho to protect the surrounds and set to with a small wire brush to try and clean the fastener.


Not much use ... on any of the 4 to be cleaned.

I then tried using a small stiff brush dipped in paint thinners ... with and without the mask. free hand and no mask gave the best results. It took a while on each Dzus, mark you.




The surrounds will easily be flattened off with a bit of 400 to 600 wet later and we should get definition back?

Paint will fill the holey rivets. 

Good night , All, nice to have had your company again. 

Ken

Ken,
Paint thinner alone dissolved the paint?
I would have thought paint remover/stripper would have done it.
You must have some pretty strong thinner there...

I think, Martin that paint stripper would have been too aggressive. Any spillage would mean a bunch of work that I do not need. And in my hands there would have been spillage ! 

The standard paint thinners worked gently as it was brushed on again and again cleaning in between applications. Because the surrounding paint was not "scrubbed" it was a lot slower to soften. What's left in the surrounds can now be easy fixed.

I had intended to use Acetone which I know eats into automotive acrylic like crazy. I took the slow boat to China.

Just a thought, choke servo very close proximity to hot engine. Servos do not like heat and the risk here is that it may start to hunt back and forth, I had a model do just that with a little hitec 422 servo.

cheers
Peter

back to lurking and being confined to home with nothing but netflix

Peter,
After 12 years it probably is safe where it is.
As a precaution though, Ken may want to
put in a fresh servo.

Shes coming along nicely, soon you'll have a brand new Lysander (well almost)
