[AT] Haywagon update

[Cecil Bearden]

Spencer:

It really doesn't need to be welded continuously.  I would suggest a 
1inch long weld every 6 inches or so.   Hopefully the groove is on the 
bottom so water will drain...........
Always think of things like that after they are done..   If you want to 
keep the groove apart while welding, I would insert he inner tube, and 
then drive a welding rod in the groove.  or, a strip of 1/8 or 3/16 HRMS 
would hold it open and then you would only have to weld on each side.   
I would try to NOT push the strip down to where it was touching the 
inner tube.  Twist the inner tube to be sure that it has plenty of 
clearance.  If the groove is where  water will run into it, and you 
don't want to weld continuously, Silicone sealant will seal it.  If you 
do weld continuously, only weld about 2 inches at a time, then go to the 
other end.  and after about 6 welds I would let it cool completely.   It 
will curl due to the weld shrinkage in a heartbeat..    A mixture of 
Never seize and grease would also help the inner tube to stay free.  If 
there is any way you could replace that outer tube, it would probably 
save time.  Around here we  use 2-3/8 and 2-7/8 oil patch tubing to make 
sliding pipes.....

Just my $0.02.   In my earlier years, I did a lot of "thawing" frozen 
parts.   Without my Dad around to help, and my joint problems, I don't 
get a lot done any more.  It takes all my time just to take care of my 
cows and keep my hay equipment running.

Even with penetrant soaking for a few days after cutting a groove in the tube, a bobcat could not pull  that thing apart.  So I tried twisting by picking up one front tire with the bobcat bucket and it did create a twist. So I set it back down and pushed to twist it back. Try pulling again and it still wouldn't separate.   So I picked up  the other front tire and got it to twist. Set it back down. This time it pulled apart ever so slowly but it finally came.
