To take the variability out of the laser beam you have to "shoot" through cross-hairs mounted on both sides of each wheel pant. The laser pens are horribly inaccurate from a "beam alignment to case" standpoint, but the beam by itself will always be perfect. I made cross-hair templates and taped them to both sides of each wheel pant. Then taped white thread onto the cross-hair marks. I then shot through both cross-hairs on the first pant across to the far pant. Remember to put the wheel pants on dollies so that they can move as the weight is added. My camber alignment was 8" out on one side and 3" on the other at 1250# gross weight. Yikes! This makes the laser very accessible and easily adjustable. To align the hole, the outer cross-hair template is re-positioned until the beam shoots through to the inner cross-hair of the far pant perfectly. If anyone needs to discuss the procedure a little more to understand, call me at (303)977-3758 days, (303)688-6099 eves. It works and is not at all difficult to do. ~T~ -----Original Message-----

Subject: Re: [Q-LIST] Axle locations I have to agree with Mike on the laser being more trouble than it is worth. I am redrilling my wheelpants after remounting the right one and finding the left one lining up on the leading edge of the opposite wheelpant right under the canard when eyeballed (and lasered) through the axle. I turned down a couple of aluminum bushings to fit finger tight in the axle and found some phenolic tubing with 3/8" outside and 1/8"inside dia. that fits inside the aluminum bushings. This assembly dials out at less than .001 on the lathe, yet when installed I can move the beam at least five inches in all directions at the opposite wheelpant. Inserting a brass tube with a 1/16" bore gets it down to about three inches which is still unacceptable. I'm going to sight it first and then use a string for final checking.

After 15 years the canard creeped enough to be about 3 degrees camber - see http://www.geocities.com/CapeCanaveral/Hall/1653/r2.html could still fly and land but it was touchier. holes.
