Help? Blade grips too snug

[jabull]

Ok, so after 4 tries of assembling and dissembling.. i suppose it's time to ask the team why my blade grips are too tight? pulling out the set of the outer most spacers seems like about the clearance i need to allow the grips to move freely.  I have verified that the bearing races are seated etc.  any tips would be a great help.

Do you mean that when you tighten the spindle shaft screws the blade grips feel ratchety as you turn them?

[jabull]

not really ratchety like the bearings have issues as much as way to snug with too little clearance and not smooth.

Perhaps the innermost thrust bearing race may not be seated all the way in.  Sometimes they require heat from a butane torch to seat all the way in.

We can all rest easy now  turns out that even after multiple tries, the problem was that I mistook inner and outer races and had a pair of inner races on one side of the grips and a pair of outer on the other. Using the spindle to validate that I had the races with the narrowest center diameters to the outside and largest inside diameters to the inside solved the problem.  Thanks for the help, and hopefully this will help anyone else with a similar problem.

John,


Lets be perfectly clear.  The issue was a builder oversight not an issue with the thickness of the bearing races... A common builder mistake though.

Alan, your correct.. and I've updated my reply above to reflect that.  The issue certainly was mine not quality control. In fact, it's a testimony to how close the tolerances are that a little slip like this made the difference.
Thanks,
Jeff

Sorry Jeff.  Called you John.  Sorry John


Believe you me I have done that one myself!  So let's get that puppy flying!
