Here we need to get the pants 1.5″ from the axle as the split point. We need the nose and the tail the same height above the floor at there respective waterlines, previously marked. Finally if we measure the nose and tail mid point to that bit of cotton on the floor then chances are we will be inline. We still have the 3/8″ pad on the top of the tire so that clearance is good too.
You got all that? I hope the pics help. I found my pants sat at 7.5″ off the ground to the center line and about 5″ out from that parallel cotton line. The other pant was a bit further out, hmmmm.
As the pant cut out is still tight on the tire I found I didn’t need the jigs at all. I could say just drop the nose a .1″ and it would stay there. I found I could move the left to right of the pants to get them straighter and they would sit nicely.
After a LOT of checking I got my hammer out and hit the pants in a ‘controlled manner’. After that was done, I set it all up for the other side pants.
Strangely I found the floor to middle height 7.75″ on the second pants so a .25″ difference. Remember my nose is up 1.7 degrees and I noticed it is not exactly perfect on the jack, just slightly to one side. It could also be that my padding is thicker one side or the wheel in is a touch different. OR maybe I have the axles drill .25″ lower on one side. I’ll let you know if I can’t taxi straight in a year or so… Meanwhile I decided the air doesn’t care about the differences that much and pressed on.
I guess my chances of a perfect show plane went out the window a while ago anyway.
Cotton line 24″ from the center line, it was just an arbitrary amount. As long as front and back are all 24″ there is about 5″ left to measure which seemed fine.
Distance from the center parallel offset line and measuring up to the center pint of the pant to get height.
Height and distance check at the back. If front and back match and the cotton lines are true, you’d think the pant was straight and matching parallel heights front and back. The plane is already 1.7 degrees up so we are in line with the airflow in cruise? I’m going with that.
