Control swivels or Ball joint linkage

Some cowl flaps have steel quick disconnect.   http://www.mcmaster.com/#control-swivels/=wvub79  Sometimes even LASAR needs a hand.

In things that bother me.   The Starboard ball linkage joint is still missing the retaining sleeve to hold the ball in. This is on the control rod that holds the cowl flap.  It was safety wire tied back together.  I could order the McMaster Carr replacement, but the linkage is coarse thread and the one on the plane if fine thread.  Then I would have part of the wrong part laying around and I only need the retaining sleeve and spring.  Some of you know how a lathe works some may not.   So here we go.  And I get a chance to use the older than me 9" South Bend Lathe.

 

First step is to face and center drill.   The center drill has no play in it so it is more accurate.

 

 

Next we step up the drill size not to final size of 31/64  But a random size.  The will let for a better final drill sizing with less wobble.

 

 

Final ID  Internal Dimension drilling operation.

 

 

Dimensioning the OD or Outside Diameter This lathe operation use the half nut on the feed screw.

 

 

Use a hacksaw to cut off the sleeve and file a bit to clean up the edges.

 

 

I think it has taken me longer to do this post than it was to make the piece.  I already created a spring out of safety wire.  The lathe and the plane are in two different cities so the final pics should be up later in the week.

The cowl link rods on Moonies are threaded 1/4"-28 NF. It seems that your link may be the wrong one. Other than that I admire your efforts to save &5.00.

and $18.00 shipping.   If I add in the depreciation cost of the lathe and tool bits, I am actually making money

I hate to buy something when I know I can make it myself and I hate to pay someone to fix something for me that I can fix myself  even if it costs more and takes longer.
