Using the same material I was able to do 36 feet solo. Wasn't easy. Once I got to about 24 feet, I would slack off one or two of the guys and then add another section and push up repeating the process several times until I reached the 36 foot mark. You really have to time all your movements and have pretty calm conditions. The center ( base) would vary as I did this but was  the best way to accomplish this. Once at full length It was a matter  of trial and error to center it all up but it worked out without help.  

....kinda like buying a yacht and using kite string for the anchor. If you want to have a repeater on the cheap you will have a cheap repeater.  Sorry,

 My guess would be that it doesnt like the antenna. .
       Try to key up at minimum power and see if it will remain operating. If so increase the power until it kicks off, then you will know that you are at least  operational until you can fix the cause.

Found this perhaps you can find more info in the book authored by Bill Orr

My first antenna was a MulTee constructed from the W6SAI Handbook back in the early 70s. The antenna was attached to the side of the house and used the house plumbing to a ground. Believe it or not it had a good match on both 80 and 40 meters. I built it with thrown out television twinlead that I found on one of my alley pickin' journeys."

 I believe you are saying that you already own this tower and are looking for a means to fold it over without lowering it. My thoughts would  lead me to think that this would be rather difficult as the tower would  not be designed at the joints or section overlaps to accomodate the stress generated by the force of being tilted during raising and lowering. Thus the reason for crank ups being a completely different animal than tilt overs.
   Perhaps you could give ua a make and model number?

 I would disconnect what you can and not worry about it.
     Remember "You dont hear the one that gets ya'"

   I once bolted about 20 feet of fiberglass "painters pole" type mast to my 4 ' vent pipe. I guyed it appropriately to hooks lag bolted to the roof joists through the shingles and had my 2m Yagi and rotator on top. Used it for maybe 2 years until I went to a ground mounted mast. Granted not sure how long your dipole is so its drag may negate this idea.
       Good luck

 The best I have  seen is one with diagrams indicating dimensions as wave lengths applicable to the frequency of interests.

So you have to do the math yourself I guess.

Most dipoles are half wave so you really only need 260 feet or so of wire , half on each side the feed point.

  50 -40 feet of this stuff will be  heavy and will need much physical help in getting it upright. Bad thing is if it starts to bow while raising you are done as it will never straighten out.

All antennas "work" but how well depends on:

  1.Feed: End, centered, off centered or loop?

  2.Intended bands?

  3.Power?

  4.20 feet not too good in any scenario .

   

 Have you asked Texas Towers?  Quite often the vendors have product information readily available and at the very least would probably be very willing to resarch such a query if it might lead to a sale.
   

You best use insulated wire, mine runs over under and through the canopy in my yard with only about 75 out of the 270 feet in the clear. It remains my best antenna.

 The alpha delta people seemed to only suggest the use of coax.

 No reason for it to not work, you're sure you have a clean coax to element connection , this can be tough with galvanized wire.
