It is a similar setup to that used on an automobile. Simply using a flange and pin setup does not allow this adjustment and the wheel would probably wobble as it rotated.

This is for both the Air-Camper and Sky Scout, one with a straight axle and the other with split axle. The plans call-out for 4 of the collars for the straight axle. Seems like you could use different thickness washers as shims to get the correct tightness. Skip - >This brings up a question.

Eye bolt ends are double nutted, lock nut over a regular nut used as a jam nut.

Tapered bearings must be drawn up tight against the race. The F&G Manual shows wheels with bushings. Some older aircraft wheels have straight bearings, but most modern wheels have tapered bearings. I don't know what motorcycle wheels have, or whether it differs from one to another.

But I opted to go with original design. walt 13 1/2 down out of 25 ----- Original Message ----- From: "John McNarry" Subject: RE: Pietenpol-List: Drag/Anti-Drag > --> Pietenpol-List message posted by: "John McNarry" > > The Christavia, a Canadian design, uses solid wires with threaded ends and > instead of forks uses motorcycle spoke nipples. > The nipples pass through the spar on the neutral axis and bear against > washers on angled blocks. > John > > -----Original Message----- > From: owner-pietenpol-list-server@matronics.com > [mailto:owner-pietenpol-list-server@matronics.com]On Behalf Of DJ Vegh > To: pietenpol-list@matronics.com > Subject: Re: Pietenpol-List: Drag/Anti-Drag > > > --> Pietenpol-List message posted by: "DJ Vegh" > > The GN-1 calls for solid wire for drag/anti drag.

This thing gets more complicated with each turn. Thanks for the great answers.
