Some things just don't go the way you want them to.

Trying to remove the engine from this Gilbert C/L airplane I stripped the shallow cut straight slot machine screws head which was imbedded deep into the under fuselage. So, I ground off the bitter (other) end flat with the mount and tried to drill it out. (mount is threaded) No way I could center punch it and the bit walked drilling off center.

One thing led to another and before long I had a mess.  Well, I have several Gilbert .11 engines but only one airframe so I opted to save it rather than the engine and just drilled the thing.  But instead of tossing the engine I thought of JB Weld.  Old JB has saved me many times on different projects. So, I bushed it with brass tubing and applied the JB.

Not threaded like the other side, but still very secure sitting in the cradle designed into the model.

Fuel tank is interesting. Held tight by guides molded into the fuselage sections. The fuel pickup though is some sort of ferrous metal that just rusted away. I replaced with Dubro tubing that actually works better.

I like the repaired engine. The repair looks great, and the thought of how you did it is amazing, and something I never would have thought of.

Yeah but, I sure mangled that one.  I could not use one of my better bits, had to use the longer hex headed bit to clear the cylinder.  Set it up on the drill press, aligned everything and the long bit just travelled.  So, I got out the hand drill and................ Sad

That's the offending machine screw in the engine compartment just above the cylinder head. (Picture above) Used my best screwdriver and it still destroyed the shallow slot.

I put the second Gilbert "SkyFlash" together this morning.  Still have to adjust the landing gear, secure the "Pilots", and wait for the Testors cement to dry.  Something tells me I should have washed the broken pieces at the same time as I did the fuselage.  Later.  This one shows more sun damage than the first.  Howard's wax will bring out more of the red.

The outside elevator hinge is broken. Got to figure out a fix for that.

I have used it for years, mostly on gun stocks.  Like model airplanes and engines, I bought the worst examples I could find.  You would not believe the condition of the Commission rifles that came out of Columbia, or the Ishapore #1's than came from India.  Nasty, moldy stocks that had been improperly stored for years.  

Vintage collectors like "Patina."  An application of Howard wax followed immediately by wiping would remove most if not all of the crud leaving the effect that collectors like.  A second application left on for 20 minutes then wiped off finished the job.  

Same for model airplanes.  Works well on both plastic models and planked wood models.  Doesn't work a darn on tissue though.  Smile

Used it years ago on this vintage planked T-28 that was a mess when I got it.  Took off the crud and left the patina.  Not happy with the 9 and Navy decals.  They just peel off.  Still looking for something more authentic.

On wood I follow directions.  Leave on for 20 minutes then wipe off and polish.

For plastic I leave on for around ten minutes then wipe and polish.

Edit add:

BTW I'm all caught up on projects and looking for something to do (it's ten degrees outside) I thought of this:

A little beyond the Howard wax fix I think.

yeah...that one looks like a overnight soak in brake fluid in a plastic bag. Thanks for the info on Howards, I'll find some and give it a try.
Another one of your "Rags to Riches" restorations...look here recently SOLD:
