Dr Feickert Protractor

I modified my MFSL Geo-Disc after seeing a Feikert.  I added a straight edge ruler for better alignment to the pivot point of the arm.  I always hated the guess-a-mation when lining up the arm pivot point with the G-Disc.

What can I say I have one set metric one set SAE, plus one set small for my bike, plus one set metric Long 14 inches plus for certain radio equipment, plus a set on my guns tool bag, and also about 5 or 8 separates that came with furniture to build and such, I'm not a mechanic but work with computers go figure.
My feickert protractor is still new in the box I haven't had a chance to use it yet.

I just realized I have issues

@jjss49 not your problem. 

i am fearful for the guy who bought the protractor if he can't get the right allen key for the feickert how is he going to mess with cartridges!!!

There's a 2nd set screw found on the underside of the tower that holds it on the plate. Usually only requires unscrewing for shipping purposes.

Just curious....

I've owned and used the Feikert many years. When I purchased it, there wasn't a hex wrench with it. What is it used for? 

There are 2 adjustments for the jig via thumbscrew.

A guy with a protractor would also be a guy with a complete set of Allen wrenches, both SAE and metric.  Like me.

Thanks for your replies - there really helpful. 

Just checked my own. It's 2.5 (this obviously in metric)

Just buy a complete set from Harbor Freight.  They are inexpensive and your customer will find the one that fits.  BTW, I doubt one could even purchase just a single Allen key.
