[Boatanchors] Wish List (temp name: Dayton List) ... *LONG*

[Michael]

I know this is late but 
 *sigh* 
 personal issues

 

All you folks going to Dayton, I have a shopping list however won’t be able
to cover anything until 1 June when the eagle does his thing with my VA
pension.  If nothing comes by this, I shant be all upset and stuff[1] but
rather will just keep my beg list (which is what this really is) going until
it’s all fulfilled.  Sooo 
 to preserve order in the universe and to keep
from seeing this aperiodically but frequently, which is probably more
important, it would be kind of cool if at least one or two items would be
able to be removed.  That way I’ll get all happy and won’t remember to post
it for a while.  All would be a fantasy come true but not one I could
afford.

 

This list is items needed for the assorted ARC displays.  A separate one
later down the road will cover other projects and whatever I missed on here.
Unless otherwise noted, quantity is one each.  Used (and experienced)
condition is fine with occasional additional notes.

Notes:

[1] Not true.  I’ll likely go out and have a good hearty pout followed by a
sulk at length.  

 

[2] What’s needed here is a decent dynamotor assembly to go with the primary
SCR-274-N rig and a scrungy BC-456 to go with the shop-assembled
Jeep-mounted SCR-274-N from the 1943 photograph I’ve posted a few times.
The modulator can be dinged & dented but otherwise sufficiently intact so
that it can look right although “experienced” and work more or less
properly.

 

[3] These items should be restorable to more or less original cosmetic
condition as well as full function.  For the grey or black wrinkle items,
holes can be allowed since they can be patched and wrinkle paint can hide a
lot of “sins.”

 

[4] This I don’t seriously expect to happen at any sort of affordable amount
but I thought it was good for a laugh.

 

[5] These ARA/ATA & AN/ARC-5 components are interchangeable for my purposes.


 

[6] I have a push-button C-30/ARC-5 that I can use if one of the other
control heads doesn’t appear.

 

[7] Only one coil set is needed.  It will go with my 47141 Tx coil for 40m
operation.

 

[8] These are interchangeable so I really only need one version or the
other.  I still need three total though.

 

[9] This can be anything from two of each to four of one or the other since
I can file down the keys for the “wrong” ones.

 

[10] I only need the actual rod itself.  I have the base and a broken rod.

 

[11] These can be single needle VOR/ILS indicators without glide slope
indication.  I don’t know the ID for them.  Sorry.

 

[12] This is the wire used in civilian aircraft through the 50s and into the
60s before it was phased out for new installations.  I’ll be using it for
the majority of the ARC Type 12, Type 15 and later equipment.  For my Type
11 and Type 15(A), I want to use the earlier woven fabric over rubber wiring
that was still in use in the early 50s for new installations.  (That is
fairly easy to find via auto restoration supply houses.)  I can probably get
away with #22 in place of the #20 for most wiring not carrying primary
current since the current is low and the wires relatively short.

 

[13] I need to make single screw tie strips for the SCR-A*-183/-283 and
GF/RU junction boxes.  These will be 3/4” wide and 3/8”-1/2” thick black
phenolic or something I can pass off as black phenolic.  Each one will be
5-1/2” long to accommodate five connections and two mounting screws.  Each
system needs four such strips for a total of twelve plus a spare or two
“just in case.”

 

[14] For the primary SCR-274-N and assorted Type 12 & Type 15 displays, I
need 15 tuning cables about a foot long and four 3-4’ long.  In addition the
roughly 3’ long cable with the MK-427()/ARC test equipment is only the
housing with no inner cable.  That’s 20 cables totaling 30-34’ and requiring
40 ends for both cable and housing.  Add in 3-4’ of cable and a few ends for
the “oops” factor.  I have available two 6’ or so lengths with good ends
along with one of unknown length with one good end and one end with no
fittings and the outer casing unraveling.  The shortfall is obvious and
needs to be covered.  Mike Hanz has the drawings to machine all except the
spline adaptors and I’ll make what I can however there is still a shortfall
of cable & adaptors and I’m not sure I can make all of the cable and/or
housing ends in a timely fashion.  (I’m also not sure my lathes are up to
the challenge.  My Taig vs. his Harding?  Ain’t gonna happen!)  

 

[15] One set each of these goes to my CM-10 VHF Communicator and MK-427(
)/ARC test set.  Civilian RS-38 type mics and HS-33 type phones with rubber
cushions will go to the other civilian systems.

 

[16] Four of these are for the wire antennas on top of the display setup and
two for the marker beacon antennas underneath.  Two of the wire antennas are
for military HF use and two of the wires & both of the marker beacon
antennas are for the civilian side.  Two are to cover the “oops” factor.
The civilian ones can probably be toward the small end of the range with the
two military ones somewhat heavier.

 

[17] Two pairs of these are for home made VOR/ILS antennas (Thank you, EAA!)
and two singletons are for home made VHF antennas.  In both cases, the
antenna rods replace the usual feedthru screw thingie.  Two of the
insulators are to cover breakage or other mess ups.  

 

[18] These are for the end supports for the military wire antennas.  I may
be able to get a local wood working club to make these for me.  I hope.

 

[19] All of the civilian ARC equipment uses coax and BNCs for everything
carrying RF including leads to wire antennas.  Many of the leads are short,
going from unit to unit in a given system.  The rest go to antennas and the
length will vary.  I lost count of the total number of RF leads I need but
an upper limit of two dozen seems about right.

What was the greatest thing before sliced bread?
