Bought the workbee 1510 bundle on fathers day weekend. Was assembling yesterday and only got to step 3 of the assembly video because i ran out of precision shims. The video shows to add a shim in between each large bearing and should be 1 extra for each wheel assembly. Theres 48 wheels and only 50 precision shims. Should be atleast 96 shims according to the assembly video. Parts list only shows 50 precision shims also. So which is wrong? The assembly video or the amount of shims included.
