Originally I tried to align axle to axle in a similar way with straight edges and it wasn't successful. Also, I wanted some toe-in. I used a similar Lowes laser pointing straight ahead and straight behind from the axle. I drew a center line down the fuselage on the hangar floor and when the front beam was half inch closer than the rear from the center I locked it in. The laser immediately showed which wheel was way out of alignment even though eyeballing looked great. The true test is how it rolls. Ed Martin's here in my hangar rolls at the touch of the finger. Mine is good but not as good. Previously, the alignment was so bad, the plane would creap forward after I pushed it back in the hangar.
Paul, I aligned my axles with the tires off. It could be beginner's luck, but here's what I did.
I used this Sears level with the laser coming out one end. The other end I butted up against the inboard end of one axle. I rotated the fork/axle/laser (with the bolts finger tight) until the laser shot through the opposing axle. Then I did the same thing on the other axle. It took maybe two iterations of this, going left and right, then I tightened the bolts. Et voila. It steers and brakes straight and the tires wear in the middle.
