THE MACHINIST

On my first crow hop the airspeed was inoperative so I took the hose off and blew it out from the inside out. (With gauge disconnected) didn't see anything bad come out but couldn't blow through it before with my mouth after using compressor on it then I could   

I didn't see a small hole in the second tube but I may have missed it.  I only see one line running from the wing into fuselage so it may be just for strength.   I posted a picture of the dash so you guys could see if you're running the same airspeed gauge.  I only saw one tube going into that as well so maybe the static port is just a hole in the back of the gauge.   I didn't think about it being too far rearward. That seems plausible as well. 

Thanks again for for all your thoughts

second flight of my c model last night trying to figure out why my airspeed is within 10% during climb out at 30 degree angle or more (verified on gps by flying a box). As soon as I lower the nose it is off 20-30%.   Not sure if a static port is plugged or....................?

joey said he only has a pitot tube on his wing not a second tube which I am assuming is static  and his is very accurate 

thanks for any input

I would be interested in the wheel penetration skis if you want to sell them separate 

Thanks again for the help jim

trying to get ahold of Lenni to go look at some parts for me

Any skis or floats or cargo bag available?

thanks

jamie 

Very cool

is the weight and balance calculator something you made or an online app?

My baggage area states 30lbs. What are you able to put in yours weight wise?

It says c76 on the side but I couldn't find a drain with that model Curtis was my guess as to maker but didn't see that model 

i will give cleaning a try

anyone know the correct size O ring  for the fuel drains? I'm assuming they can be replaced? Mine are seeping

thanks

jamie

Thanks someone sent me a link to that.  I elected to use slightly wider plywood and double it

Today I fit a new wider rib cap to give more area to re-glue my fabric 

Today I  used MEK and peeled back the tape then slit the fabric along the rib cap. 

i decided I couldn't to a good enough job with the wing on the plane so off it came. 

I had to cut the lower rib cap so I will put a wider one in to replace it so I have more area to tie the fabric back into  

in order to keep the tension on the trailing edge cable I needed to be able to run from the spar to the cable so I used one piece of plywood on the right side of the rib.  In order to replace the rib I had to slit it to the point of the cable then I put a short section on the left to tie in my splice.  I used scotch weld 2216 to bond it all together. 

Should be stronger than before  

thanks again Jim Chuk for the plywood  

When one looks up piss poor in the dictionary a picture of this repair would be its definition. 

Whatever glue was used never even made it to the tip their were no fasteners of any kind used and it was only a couple inches long.  I'm sure it was just a bandaid to sell it.   Grrrrrrrrrr. 

The up side is there was no rot and structurally all looks well aside from this isolated damage.

Does anyone have any info on how the repair is made in England using the aluminum sandwich.  

I guess I will order the hysol what size do you think I need to repair both sides with the counter balance (one on each wing) by sandwiching aluminum on both sides?

thanks

Jim

thanks

I called you back but it rang and rang

is there any substitute for hysol 9460 that I could buy at Home Depot or Lowes?   I can't find hysol locally and was hoping to do the repair this weekend. 

Thanks

jamie

My plan is to cut out the damaged wood and put in new wood and sandwich that with aluminum

jim

edmo is exactly right that is my plan 

Does anyone have a STOL wing open they could take measurements of the triangle to the tail of the flapperon so I can cut some aluminum to fit in and sand which my splice.  My plane is an hour away and was hoping to get the aluminum cut before I get there.    I think I will reinforce both sides where the counter balance is. 

Thanks

jamie

Edmo 

 think I will try to sandwich it as well.  How long ago did you do your repair and any issues since?  If I use a poly system solvent to peel back the tape can it cause any damage if it isn't a poly system product?

jack.  It moves smoothly throughout its range of travel.  All I can figure was hangar damage. Repaired poorly and maybe stressed by trailering. 

I hope it doesn't break again   One with rot caused a crash in the Midwest.  I think the guy ended up in a river I think   

Thanks guys

Unfortunately it is cracked through and moves

Sadly on my first pre-flight I found a broken flapperon mounting point above the anti flutter counter balance.  It looks to have been repaired before.  I have read of several ways to repair it my question is what fabric system system was being used or recommended by avid in 1990.  That is what the aircraft logbooks say they used what the factory manual recommended. 

Thanks in advance

Need to replace my gearbox oil. 

not finding the correct amount. 

I found this nice article as well as many others  but doesn't mention if the engine is mounted normal or inverted. 

http://www.rotax-owner.com/en/rotax-forum/1-2-stroke-technical-questions/4629-c-gearbox-oil-change

Mine is inverted 

Do any of them at least have a double o ring or room to machine a groove for a second one to be added?

That is not very comforting

i may look for one from a piper or something to rebuild and swap. 

Great info 

thanks

i will rebuild the old one for a backup

Great pictures.   Someday will make it happen.
