Yup, Lowes and Ace Hardware also
 
Jack I was chuckling when you posted the plastic blades.
I bought these with the same thought about gouging alum...but I never used them :D
Think they'll be used in the bathroom to remove old caulk in shower :s

I picked them up at Auto Zone.

I'm running 0.003 run out right on . Is this questionable for gear drivin timming ?

.003" was the old factory warranty spec for crank runout before the MoCo went off shore for cranks and changed that spec for the new cranks in 2007. That same .003" has been the general guideline for max TIR for gear drive cams. However, back in the day before the hydraulic tensioner setup I have installed gear drives on cranks with .004" runout with no issue and would say that .0045" would be the max but outside the generally recommended clearance parameters. An OS or US gear, or both may be required and they may be a bit more noisy once set up with proper clearance but will run without issues.

Having said that, faced with more than .003" TIR today, I would recommend the hydraulic tensioner setup over gear drives. JMHO.

Thanks Dolt .
When you set up gear drives on .004 cranks, did you use under sized gears ?
F.K.

No; the lash was a bit loose per Andrews specs and been a little noisier at idle but not noticeable unless you were listening for it.:coffee

Here's a link to S&S gear drive instructions:
http://www.sscycle.com/files/3013/7033/9860/51-10471.pdf

Page 4 recommended crank/pinion runout
Page 6 talks about gear backlash/clearance

1st you assemble standard gear set, then measure backlash to determine if you need a under or oversized crankshaft gear which will be a separate purchase.

Also note you will need a cam set for gear drive set up, "Gear driven rear cam rotates in opposite direction from chain driven cam."

I understand run out and how to check for it . how do you check for back lash .

Thanks F.K.
