I decided to try a new painter's tape.  Its called Frog Tape.  What is it?  Hmmm, its green.  

I have been using blue painter's tape and it is ok, but if I run flood coolant it sometimes picks up.  The green Frog Tape is supposed to not allow bleeds of paint under the edge like the blue tape can sometimes.  I thought, hey maybe it will work with coolant too.  If its reacting with the liquid at the edge to form a seal maybe it will do the same thing with flood coolant.  Water and SC520.  

I make a type of part fairly often called a divider plate.  Its used in minnow molds to create a hook slot.  It usually has a couple holes drilled in it for placement pins or screws.  In the past I've used the blue painter's tape and super glue trick.  Then I'd drill the holes first, drill a hole below in the backer plate, and tap that, then shoot screws in.  The screws would keep the divider plates from moving while the profile is cut.  

I'm doing the same thing with 20 divider plates right now using the green Frog Tape.  I left 3 plates unsecured.  They are cut out and all three unsecured plates are still in location.

Here.  Clean up pass done. 

I'll probably still use the screws when I can, but its nice to know it held.

I did not put in or take out all those screw by hand.  I used a cut off hex key in a cordless drill with a screw driver clutch.

McMaster sells the hex drive hex keys. I just bought a 6mm for my metric vise jaws.

'Good to know about the Frog brand tape, Bob.  I have both the blue and 'Frog'.  Now I have a new use for it, besides just painting!

And what Gary said... I have two whole sets of hex keys with 1/4" hex-head drivers.  I couldn't live without them.

I have several of sets of hex drivers.  1/4 hex and socket drive, but they are the short ones.  I don't like using them in extensions.  I buy 1/8, 5/32, 3/16 and 1/4 hex 'L' wrenches by the 100ct box from Copperstate Bolt Co. to include with molds that need them when I ship them out.  Its nothing for me to chop the arm off one and have a driver.  I also put a slight bevel on the end with the belt grinder so they drop into the screw head easier.  No big deal for one screw, but for 34 of them the time savings is noticeable.

I used a piece of stainless rod to burnish the Frog tap in place.  It stuck really well.  In removing the divider plates with a putty knife the tape failed at the super glue bond for all but 2 or 3 plates.  Its hard to tell, but it seemed like the surface of the tape failed.  Not the glue. 

I only gave it ten minutes or so to set, but I did spray mist some water on one side to activate it faster.  I had to use a finger nail to peel the tape off the plates.  It did peeled off nicely once started.  I used my putty knife as a scraper on the backer plate and it came off about the same. 

I was careful with prep.  Backer and stock were lightly sanded, cleaned, and wiped with acetone before applying tape.  Backer was flycut for flatness first 

Fly cut a thousandth off the backer and its ready for another batch.  Might not even need to do that.  I had the depth set perfect so that it cut into the tape, but didn't touch the backer plate.

Bob,
I have a handful of 'short' Allen wrench bits on 1/4" hex shanks, but most of the ones I have possess 'bit' portions at least 4" long, so I don't have to use them on extensions.

Pretty-much all the tool suppliers sell them.  IIRC, I got mine from McMaster-Carr.

The one I got from MMC is a ball end style which I needed and I like those better most of the time. The ball end actually seems to do less fastener damage on stainless where cam out seems to happen easily.

Maybe your hex driver is superior in every way, but even including my time to lop it off I don't think I can have a driver suited for the job any cheaper.  I literally have hundreds of them.  LOL.
