Is that measured as Dave Calkins suggests with a straight edge on bottom of SPARS at wing root??? (not on bottom of RIB or wing attach fittings). I'm asking because I also have a Riblett wing I want...

It's like the difference between a Newhouse and Victor #1 longspring trap. The Victor is cheaper, the pan is loose and floppy, and it's all stamped out, no precision to be found. The Newhouse, by...

What knot do you use instead??

I have not tried beading the 6al-4v Ti yet. It is very tough and requires a large bend radius for bending (10t I believe) so I would like to hear how you make out if you give it a try.

I was told years ago that the Piper airframes that are sometimes called "aluminized" were actually cadmium plated. Anyone that has worked on a few Pipers has probably seen one. Mostly ag models and...

I found a 3'x3' piece of 6al-4v .016 Ti on E-Bay for $80.00 plus shipping.

I have replaced LOTS of rear doorposts exactly like that, which is why I asked. I don't even bother removing the channel to look, just cut it out. The bottom end of the front doorpost by the...

Level as per cubunltd's suggestion, then use plumb bob to determine where to drill new hole.

P.S. That rear doorpost looks gnarly at the top end where the channel was removed. How's the bottom end...

I have never replaced those bushings, but heat would be a last resort for me. The dimensions will change if heated to red hot, and would probably be hard to restore.

In general my thinking is that replacing the broken tube/bracket/tab/etc is better than a patch/splice repair. they add weight, lower resale value and are usually not pretty. Make it so you can't...

Anyone with thin aluminum welding experience should not have a problem since it is likely a small crack. A major repair is another matter... takes more than just welding skill.

Hi Levi,
Great to see another stretched Pacer in the works. Very interesting about a slotted Riblett wing. I have not been able to get any feedback on AOI and stab trim, and those are key to a good...

My B&C S701-1 solenoid tops out at 126 F at room temp.

The Univair catalog has a picture of the O-360 mount for their STC if that helps.

While some people claim that tube reduces the possibility of leg/foot injury in a crash, I maintain the best strategy is to avoid impact with solid objects. There is no paperwork or testing for that...

You can build a set of Schneider clone wheel penetration skiis from a single 4x8 sheet of 1/8" aluminum. All welded, and they work great.

Remember his original airframe was a Maule. Is that what you are referring to?

If I have an airframe to repair the angle of the wing attach fittings is what you have to use as a reference to the drawing. Angle of incidence(AOI) is a theoretical relationship between wing chord...

The increase of the front fitting height to 2.875" from 1.6875" will increase the angle between attach fittings by 2.2 degrees. That should increase the AOI by the same number. I'll leave it for you...

The numbers I gave are according to Piper drawings, however that will vary in the real world. What your "range of acceptability" is will vary as well. Airframes while appearing to be very rigid, in...

If you do the math, 31" between fittings and 2.5" vertical difference (per the drawing), you get about 4.6 degrees angle from horizontal. Sounds like you are in the ballpark in that respect. The...

DC Inverter, 120volt, fewer knobs the better, any color, with hand throttle will work fine. Use 1/16" gas lens collet bodies (2 series, air cooled). CK Worldwide makes my favorite torch and slider...

What is the favored hose for the wing root connections since mil-6000 is no longer recommended?

Unfortunately the vertical tube does not replace the clamp-in tubes required by type certificate. However, like I said above, most people don't know it's required and you may be able to get away...
