I have completed making enough of the tools for the people who expressed
interest earlier.  The cost for one fluted #8 Bristol wrench is $9.50.  That
includes 1st class mail postage with delivery confirmation and no insurance.
Without insurance the mailing will be at your risk.  If you want it to be
insured the post office wants $1.70 more for insurance from $0 - $50.  With
insurance (your choice, but without is your risk) is $11.20 per tool.

 

A couple of people wanted three.  The cost of postage will change.  The cost
of three with postage is 31.20 and includes the $1.70 for insurance.  The
insurance fee does not change from one to three wrenches.

 

If you still want the wrenches let me know again.  I would prefer a money
order.  My address is correct on QRZ.com, or I can provide it individually.
When the money order clears the bank I will mail the tools via 1st class
mail.  Any of the other common options for mailing are available, but cost
considerably more, and will increase the cost of your shipment.  [Richard

Upon request I can send you a picture of the first nine tools I made.

 

This tool is strong and does not have as flexible a bit as some commercial
tools which can be problematic working with some of the clamps on the gears.
The bit is very hard and will not wear down as fast as some of the other
tool variants.  This tool does have some flexibility in the tip to give you
some indication the spline is tight before snapping, stripping the head, or
breaking the clamp.  The two inch long bit will flex slightly.  This tool
also allows you to twirl it in your fingertips when aligning the RF deck.  I
enjoy this tool and originally made it for myself.  

 

Again if you wish to make you own I will tell you how I made them.  There is
no magic in it, just having the right materials and tools.
