 Think that would work in bolt holes in the prop hub?

  

 I used silicone seal to fill holes in the gear box.  Hesitated to use it on steel after some severe corrosion using it on a 4130 tail wheel strut.

That's good info Herb.



I used silicone to plug all the unused holes in my suzuki engine.  They were subject to the same mud plugs.

I would hesitate to use great stuff.  -once made a vehicle rust out twice as fast by injecting it into all the hollow panels.

Turns out it wicks moisture -and salt.  

For a temporary fix on the prop hub a patch of duct tape stays on fine.  Not very high tech looking.

I don't use the back up disk on my two blade warp hub so I found a rubber plug that fit the center hole perfectly

Sometimes it pays to save old stuff.

Try the auto parts store; look for 'sensor safe'. (meaning     non-corrosive)

 if you get the aluminum duct tape,,  available  at hvac (heating vent air conditioning) locations...  cut to fit, pull  the backing and it stays put well and looks good.

 Folks:

  

 Thanks for all the recommendations.

  

 I like Boyd's idea of aluminum duct tape.  It is light,  can die cut enough to cover the holes, and should not affect  balance.

  

 Darn mud daubers are a pain in the butt.  They have  several places around the cylinder bases on the crank case they love to build  homes.  On top of that, where they build their homes is difficult to access  and remove.

  

 Clear, sunny, and cold.  Still too cold to fly  comfortably, unless I get serious, get out the Chillie Vest and long  drawers.

John, If your hub has the small, 1" hole a plastic cap off a Blitz fuel can fits perfectly. It's been in the hole of my trike's Power Fin for almost three years now, weighs little and I always have a gas cap handy should I need it.

 Rick G/Gang:

  

 I have the large hole covered with a prop spinner.  It is  the unused bolt holes exposed on the forward side of the prop hub that need  plugging.

  

 I need to pull the prop and extension, clean everything up  good, then take care of plugg/covering to prevent the little rascals from  homesteading again.

  

 I also need to make a cover for the aft end of the  tailboom.  Probably out of hardware cloth or screen wire.  Something  that is easy to slip on and off.  Probably end up with something that is  two piece, protected with duct tape to prevent scuffing up the paint when  removed and installed each day I fly.

  

 After the rodents have gotten in and done their dirty deeds,  it is too late.  All it takes is one trip in and they can destroy seat  belts, shoulder harness, seat covers, wiring, and plastic brake  lines.

John,

 A lot of cold air and exhaust fumes blew up my tail boom,so I made a plug of 6" thick foam rubber, 7"in diameter with 4 slits cut for the cables at 12,6.10 and 2 o'clock approx,placed it about a foot up the pipe.Seems to work OK.  Cut it on a band saw.

 That may be a good idea.  No telling what is being blown  up the tailboom and into the cockpit.

  

 The important thing for me is to insure the rodents won't chew  through the foam to get into the cockpit.  

  

 I have to be careful.  I do not want to trap  condensation, rain water, etc., inside the tailboom (a very intergral part of  the aircraft).

  

 Need to do something positive though, before the rodents start  looking for new nesting areas.

John,

  

   Regarding rodents, etc.  Try putting a "mothball" puck (toilet bowl hanger) in

 vulnerable areas.  If you are concerned about the puck harming any surrounding airplane

 parts, make a little basket for it to sit on out of aluminum foil.

  

   Be sure to list them on your pre-flight inspection, to remove them and set aside 

 during flights.  I would think three ought to do it.  Your experience may vary.

  

   No self-respecting mud dauber, or mouse, rat, squirrel, chicken, etc, could stand 

 the fumes!  Guaranteed to last 90 days, depending on use....they say.

  

   Might be worth a try, supposedly works for deer in your garden, although I can't

 say if it's true or not.

  

   Awhile back, I was walking in my shop, when across the front of my eyes flew a

 small "wasp" looking insect.  It was really small, missed me by about 4".  I turned 

 my head to watch were it was headed.  It landed on the open fuel line to my GEO

 engine (which was disconnected so that I could remove the engine).  Then it proceeded 

 to walk inside the fuel line!!  Evidently, it had a nice nest going on inside the fuel line.

   I disconnected the fuel line completely, and removed it altogether!!!  I have since 

 replaced it with automotive high pressure rubber fuel hose....with a filter!!

 Mike W/Gang:

  

 I have done moth balls, rat traps,  mouse traps, DECON rat poison, etc.

  

 The best approach has been blocking  the aft end of the tailboom with scotch brite pads.  This year something  got in through the pads, took a couple nips out of the top edge of the right  seat back cover and the edge of one shoulder harness strap.  Everything is  still serviceable.  Could have been a lot worse.   Or it may have  gotten done the three months I was rocking and rolling in the wheel  chair.  I am not sure. 

  

 In the past I have had seat and  shoulder harnesses, wiring, and plastic brake lines cut.  They cut the  brake line completely through, hydraulic fluid and all.

  

 I think I will probably go with a  hardware cloth or sheet metal split cap of some sort to mechanically keep'em  out, or try to keep them out.

  

 Thanks for your  suggestion,

Better to use 1/4"

 Larry Cottrell has a herd of good  sized bull snakes around his place.  Should have brought a couple back to  Alabama with me.

  

 No one living in the old house out in  the pasture where I have my airstrip and hanger.  If they were, we'd have  some cats, as Robert L suggested, if those big rats did not kick the cat's  butt.

 Don't know about deer mice, but a normal/regular mouse can  probably do the same thing.

Good evening, once again I will be at the Sebring LSA expo air show in booths 105/106 and on display will be my made in the USA AeroLIFE Products. Check out my web site www.aerolifeindustries.com and talk about non corrosive sealants that's all I make as well as my FTS fuel tank sealant in one part or in two part. So, stop by and say hello the Show is from Jan 20 to the 23rd and we even give away free samples. Have a safe trip down, see you at the show.



Sincerely, 

John T. Schmidt, CFI
