Title: In primer
Post by: Doug Moon on April 29, 2008, 11:32:26 AM
Here is my plane in Primer.  Paint is next.

Off the stand with gear on and engine pads installed it weighs 36.5 oz.  Not the lightest I have done but should be pretty good.  All up weight I am thinking 62-64oz total.

Looks good, Doug. My Classic plane is in about the same shape. I jsut started sanding the primer. I layed it on a bit heavy and so sanding is taking awhile.

Thanks Randy.

The primer on this one is for dry sanding.  Like sitting in dust bowl after two full applications and sand off. 

This a Sherwin Williams automotive primer, in a rattle can but fills like you spray it from a rig.  At $9 per can it better.  Be ware it weighs a ton!  The cans are very heavy, tons of solids in there.

Eric V and Brad turned me onto it and it is very nice stuff.

Looking good, Doug.  Yeah, the *fun* starts now! LL~  Sand, sand, sand.......

What size is it and what power train?  I see a *touch* of Gieseke in it. ;D

I am really hoping to get back on my Hunt Mustang (like Danny Banjock's but converted to a *B* model) very, very soon.

Doug,

I've used automotive primer/surfacer lacquer with good success. Matrix and Duplicolor both work pretty well. My current plane is using my own custom supersecret formula for primer.   ;D

I noted elsewhere that I found a new (sorta) trick. I shot on a coat of primer and it was a bit thin so I thought I'd shoot a second coat. Unfortunately, I had to mix some more primer up and the second batch was quite a bit lighter in color than the first (the first coat was dark gray, the second light gray). Made sanding pretty easy because the lighter color stuck to the low spots and were very easy to see as I sanded. Made for a great visual cue.

Thanks for the comments guys. 

The plane has a Geo Bolt wing, 26% flat Stab/Ele.  My own style Fuse, similar to many others out there. 

Traditional constuction, maple beam motor mounts, lost foam wing.  The stab is sheeted foam using pro set epoxy and a vacuum bag.  I made a male mold of styrofoam for the cowl and then covered it in 2oz glass with pro set epoxy then hollowed out the foam.  I recommend this method it is comparable in weight to wood but has none of the fill required that wood has.  Plus it wont soak up any oil. 

I hope to get it painted here pretty soon.  Heading to English color today.  I am so affraid of the cost of the paint I need.   %^

I will post more as I go along.

Looking good, Doug!
Hey, worry not about the color cost - it takes some of the fun away from doing the graphics & design.  After you get it done, then throw away all your store slips and pretend you used cheap housepaint!  (I know it won't look like that, but it eases the mind!) n~ n~ n~ %^@ %^@ %^@ :o ::)
Blessings,
Will

This is pretty much what Pat Johnston does with his cowls. Here's a picture of his first Mustang.

Randy and others,

Here are some views of the cowl and its wood counterpart.

It is right along the same lines of how Pat does his cowls.

The wood lining I did on the glass one I trimmed it further back so it is now just a little lip that butts up against the plane.  I put Balsa inside the opening in the front to give it some thickness. The glass is paper thin and that little added balsa helps appearance and keeps the edge from chipping.
