I just wrote this all out and lost it! Damn!

This is a Very Accurate Balancer and I was able to balance my wheel to within 1 gram or perfect. The computer spin balancers only get down to 5 grams. It will cost less than $100 and is collapsable for easy storage & transport. All the parts were bought on ebay except the hardware. (Ace or Home Depot)

Okay, here it goes again:

You will need:

4 - ABEC 7 or 9 Ceramic Skateboard bearings
1 - 2" angle Aluminum
1 - 4" Aluminum C Channel
8 - 1 1/4" long 5/16" bolts
16- 5/16" flat washers
4 - 5/16" locknuts
4 - 5/16" wingnuts.

First cut the angle & C channel to 16 inches each using a chopsaw withmetal cutting blade. You can use a compound miter saw also. Make sure all your cut angles are 90 degrees/ square.

Measure & mark all your holes and use a center punch and small pilot drill bit to start them. I measured 1" from the edges to center the holes on the angle and drilled them 1 1/2 inches apart. I made about 6-8 holes on each side of each angle so I can balance different width wheels; front &rear.Drill only one angle and use it as a template to drill the other one by clamping them together.

You don't have to notch the C channel for the axle because it will sit on top of the bearings anyway; just make sure to place the bearings so the axle will slear the top. Place the bearings about 1mm apart max. Drill only one side of the Cchannel & angle and use it to drill the other side. Use a drill press to keep theholes at 90 degrees.

Use flat washers on each side of the bearings with the rounded edge of the washers facing against the bearings. Use the locknuts to bolt the bearings tight. Put it all together and try it out using your bikes axle as the roll pin.

More pics. I plan to make a woodenstorage box for my balancer soon.

You will use the bikes axle as the balancing bar. I feel it is more accurate than the cones because it keeps the center wheel spacer perfectly lined up/ centered.

The wingnuts make it easy to disassemble and it folds on itself if you remove one of the legs.

Why the bearings to support the axle?

 

Because these ceramic bearings are very low friction and the heaviest part of the wheelrolls to the bottom. The stock wheel bearings have a lot of drag especially with the grease/ dustseals.
