TAILWHEEL INSTALLATION
 

I am having a problem installing the tailwheel assy on my Tiger 60. I bought the Carl Goldberg tailwheel assy and the instructions seem to be verystraightforward. Except Icannot make it work. The instructions say to "thread the second 6-32 x 3in threaded rod halfway into the top of the brass tailwheel hub". My problemis that it will not thread all the way thru.from either direction, it only threads in to the middle of the hub, and then stops.
Am I doing something wrong? Or should I maybe just tap the huball the way thru. It acts like it is not tapped all the way. This being my first tailwheel install,I am not sure I am reading the instructions correctly. Any help would be appreciated. The link I am providing is to my build thread.

can you actually see all the way through or is the shaft for the wheel in the way? there could be a "set screw" for both sides of that wheel collar.

Whew.  For a second there I thought I was gonna have to retire and only fly ARFs.  I read your posting and ran to my shop to check.  Its been awhile since I last looked so I couldnt remember.  Thankfully the answer is yes, I can see all the way thru and there are no set screws.  As far as I can tell it is threaded all the way thru.  I can turn it in from both sides, but only about halfway.  I cannot see any obstructions.

Have you tried running a tap through it?

Not yet Chip.  I have been thinking that is the answer.  Just wanted to check with everyone to see if I was doing something wrong.

I would also run a tap through to clean the threads.

It cost me $19.95 for a cheap quality tap and die set at Lowes, but IT WORKED.  Thanks for the input fellas.  I will continue this in the Tiger build thread.  What a relief.  And it was really very simple once I just accepted that The piece I recieved in the package needed a little cleanup.
Thanks again guys.

Well I am back to confused.  The springs that attach the threaded rod in the rudder to the rod in the wheel hub are 4 inches in length.  The actual gap between the horn brackets that the spring attaches to is less than 2 inches.  I feel like such a dunce.  I just dont see the relationship between the two.  Why would Goldberg give a spring that is more than double the required length? 
The rudder rod is installed "near the bottom of the rudder, 3/4 in back from the hinge line". 
The tailwheel bracket is located "so that the top bend is close to the hinge line". 
This does'nt leave alot of room for interpretation.  Right about here the cursing begins.  For those of you who missed it, this is the Carl Goldberg medium tailwheel assembly.

Good gawd man your doing way, way, way to much thinking here. Cut the springs to the proper length. Goldberg has no clue what application is going to be used. Just be glad they gave you enough. Sounds like you might even be able to cut one in half and put the other in your parts drawer for use with something else.

You are right Mike.  I never even considered Goldberg didnt know it was going on a Tiger 60.   I just did not think that 3/4 in from the hinge line is obviously differant from one model to the next. 
I just didnt want to destroy something and then have to buy new because of my inexperiance in installing one of these things.  Thats why I asked the question.  Now that I think of it, a simple statment like "some parts may need to be trimmed to fit" in the install directions may have did the trick.  I just assumed they would all fit nice and close.  And ya , I know what assume means.  I still do it almost everyday.

Well, it looks like I wasnt overthinking this at all.  Goldberg sent me a pic of a model with this tailwheel installed.  The 4 in spring has been cut down to approx 1/4 in.  And it was possibly the ugliest instal I have seen.  Nevertheless, I went ahead and did as Goldberg demonstrated.    The stainless steel spring does not twist around the horn easily at all.  I even used my safety wire pliers.  I have safety wired more hardware than anyone could count over the years.  So I would put my proficiancy with that tool against anyone.  So, I have 1/4 in twisted wire, 1/4 in actual spring, and 1/4 in twisted wire.  It is ugly.  No other way to put it. 
I never thought a tailwheel would be such a pain.  I am going to search for another alternative to this particuler tailwheel as noone seems to have any experiance to share that will make this one acceptable.  
I will say that Goldbergs customer service has been just fine.  They guy on the phone returned the call like he said he would and did the research he also said he would.  He agreed with me the pic he was emailing me wasnt pretty.   At least he tried.

Hope this isn't too late to be of any help, but i thought i'd post pics of my cg tailwheel installation. This is the same tailwheel on a fourstar 60. (the bracket looks different because i made an aluminum one to lighten tail) First of all, it looks like you may need to move threaded rod in the rudder as close to the hinge line and as low as possible. The threaded rods were trimed to about 1 3/4" and i found some slightly stiffer springs at the hardware store, the supplied ones seemed way too weak. I then trimmed them to length and bent the end coil on the spring 90 degrees &amp; simply used that to hook onto the eyelets on the horns. you should have some tension there but alot isn't necessary. Hope this helps &amp; good luck on your tiger build.

Now that looks like a good solution.  I think the differant springs make all the differance.  I have already changed tailwheel assy's.  I wound up using the Sullivan tailwheel and it works just fine.  But at least now I know I can probably use the Goldberg on my next taildragger by using your method.  Much appreciated.
