I got a quote for the four inch long by 1/4 shaft extension for the fuel  selector valve from Glasair. They wanted $49.00. So I showed the shaft to a  friend that operates a machine shop. He took a piece of raw stock, cut it to  size, drilled and tapped one end then filed in the flat spot and drilled a 1/16  keeper hole in the other end. It took less than fifteen minutes to do and when  he was through, he said it was so little and to forget it. I  asked him what the cost would be if the part was mass produced, he  replied; less than a buck.

This being experimental aviation, you can fabricate any part you desire.

However, most of us don't have access to a buddy with a machine shop. If you

took that part to a commercial shop and said "make one", I'm sure your bill

would be more than 49 dollars. Wait until you need something big, like a

motor mount or a gear leg. Then you'll be glad Glasair Aviation is there and

will pay whatever they charge. And in order to stay there they have to make

a profit on what they sell. So, do I consider a $49 sell price on a part you

say costs a couple of bucks to make - NO.

That fuel valve  selector shaft comes off a selector valve for  home builts that only costs "$23 bucks for the whole Assembly." So I doubt if  the manufacture of that valve pays $49 just for the shaft! And as far as  your landing gear legs, when my original gear legs snapped off landing on a  grass strip and I ordered a new pair from Glasair, one leg was so soft the  left wing almost  touched the ground. When I complained to Glasair, they  replied that I "didn't wrap it properly." So I said to Glasair, you wrap  it. When I installed the replacement the wing still sagged. When I measured  the legs I found the right leg was nearly a quarter inch thicker than the  other. I decided, the heck with it I just live with it and toed in the axles so  that when the plane rolls the legs pull together. I wished I had ordered the  after market Whitman aluminum legs that were less expensive and far easier to  install.
