I need to rebuild T10 on a series II Lazair. I can only find 0.065" and 0.058" wall thickness in 1" tubing. I need 0.062" giving 0.875" ID. Does anyone on the list have a source for 1" 0.062 wall 6061-T6 in eastern Ontario.

Thanks,
Bill

Bill,

.065 is super close to .063. With only three thousands of an inch difference I would think that would be just fine. If not, you would use some sandpaper or something on the inside to take it down a bit. If you do that, don't forget to use some alodine or equivilant to protect the tubings surface.

I don't know what part you are building, but the reason they make the tubing .058 thickness is so it will slide together with a good fit. If it were a perfect fit it would never go together. On one of my previous UL the wing spars were sleeved tubing. They used .049 wall tubing, I can only assume it was to make the tubes slide together easier on a long length.

Bill,

My records show that my series 1 was supplied by Ultraflight with a
pair of 1" X .058" X 56.25" long, 6061-T6 T10 tubes. BTW, 0.062" (edited) is
not a standard wall tubing thickness for 1" aluminum tubing, it would
be .065". Airparts in Kansas City and (my favorite) The Dillsburg
Aeroplane Works, 114 Sawmill Rd. Dillsburg, PA 17019 717-432-4589
should have it in stock too.

Also, those wall thicknesses are nominal, and can and do vary
somewhat. As the dies used in the manufacturing of the tubing wear,
the wall gets thicker. If you can actually go to a supplier and take
your plugs along, they might let you rummage through their stock and
find the best fitting tubing.
