Hi All



I am about to assemble my tail plane torque tube for the first time and

need some advice.  This is from an approximately 1999 vintage Trigear XS

kit if that affects the answer.



I have pictures showing the torque tube assembled on a bench by a previous

owner so I know the parts fit together.



The parts such as TP12 and TP9 are an extremely tight fit over the tube TP4.



During summer I managed to partially install TP12 on the end of TP4.  This

was after the parts had been sitting in the car and they were quite warm.

This makes me think heat may be part of the answer.  I don't know the

temperature they reached but it could have been up to 35 degrees C from the

car but more likely about 25.



Now when I try to remove TP12 it won't budge.



I'd appreciate any suggestions or advice from those who have done it before.

Thanks

Graeme

Hi Graeme,

 

My kit around 2000 I had the same problem.   I spent a long time trying to lap the outer parts for the tailplanes to the tube.   I think that is possible but I gave up and got a replacement tube from Europa.   I believe that kit was No 517 or thereabouts.

Thanks Alasdair



My kit is American but the original British paperwork has the serial numbers 467 and 450 on it and is dated March 98 and March 99 so it is a very similar vintage.

With the problems some have had with movement around the tube I don't mind having a snug fitting tube.  The 230 pounds for a replacement and freight half way around the world are also a strong motivator for finding a solution using the existing parts. 

I might try heating a room to 35 degrees C and putting the parts in there for an hour or two to see if that loosens them up.  Another option which I will follow anyway for enlarging the holes to take a 3/8" pin is to find someone who is an expert with metalwork and get them to do the job.  Even if I have to pay someone it will be cheaper than buying a new tube and I'll know the job has been done properly.

Graeme…when I initially thought about enlarging for the 3/8” pins, I assumed I’d just use my trusty drill press…FORTUNATELY, before doing so, wiser heads prevailed and I took the assembly to a machine shop where the work was expertly done.



Given that this assembly is a critical component for safe flight, caution and care are called for to avoid a sloppy fit.

Thanks Fred. I don't have a drill press I trust so I will definitely engage a professional. I also have a spot of welding for them to do.

     If you had been across the ditch on the great West Island I may have     had some contacts for the machining job. I had mine reamed out a     long time ago.

Thanks Lance.  I plan to ask my mechanic for a contact to do the machining.  I believe it should be a pretty simple job for someone with the experience and the gear.



I managed to get the parts to come apart by soaking them in a bucket of hot water.  A smear of chainsaw oil all over the tube made my next attempt at assembly and disassembly much easier.
