Well here's what I ended up building. The vertical pieces plug in to the bases so if you need more height you can drop a shim into the base for the vertical to sit on - if you need less height you can cut the vertical, and the top portion can pivot to match the angle of the underside of the wing. Theoretically, when we put the struts back on we can pre-set the washout angle at the top of the stand, and get the wings in the ballpark, checking it and making fine tune adjustments using a digital protractor.
I think that if you could get several sets to do at one time (ultra-sound) the cost would be cheaper. At least that is one of the local guys told me.
Replacing one set of struts at a time reminds me of the story of old Porky. I'll have to tell that one when me and Curly get to have that beer together (Foster's of course).
This place is being pretty reasonable. $125 to do the Ultrasonic AD on the struts, and $75 to do the AD for on the forks. They say I'll get a printout showing exactly how thick the metal is. I had a couple hundred hours left on the forks but figured what the heck, it hadn't been done since the early 90s so for $75 let's just reset the clock.
Just got the email, my struts are done. The AD says: "A measurement of 0.024-inch or less shall require replacement of the strut prior to further flight." The report on my struts says nothing less than 0.035. No cracks in the forks either. Total cost, $200. I'm sure doesn't make the sales team at Univair happy, but it does me!
Now that it's time to put the struts back on, I've purchased a gallon of Linseed Oil and am looking for ideas on what kind of apparatus to use to inject 1 quart of the stuff into each strut through the small hole at the top that takes the sheet metal screw to hold on the strut cuff. What do you guys use for this?
You can buy big syringes like Tony suggested at farm and ranch supplies. I remove the strut fork and oil it from there and then slosh it around, coating the inside of the strut and then drain it all back out.
