Just received 4 5-pin coils from Antique Electronics.  Price was $5.50 each.
These do not look like NOS.  The body is a hard plastic (not bakelite).
The pins are epoxed into a thin phenolic base, which is also epoxed to the
body.  I've seen better.  Ocean Side Electronics also sells forms.  Made
my own out of PVC, fiberglass, and brass tubing using hand tools.

Helm,

Would you please send a more detailed description on how you made your
coil forms.  A picture to my mail box would be great. It is good that folks
are building the HBR reviver.

I agree.  The base doesn't look very sturdy.  It would be interesting to
find out the quality of the forms sold by Oceanside in FL.

I have 3 here from Oceanside, the form is paper and the pins are weak.
After changes in the HBR they will be loose.

I used PVC tubing I found that was 1 5/16 OD.  The base is fiberglass
sheeting similar to PC material but without the copperclad.  The pins are
1/8 OD and 5/32 OD brass tubing obtained at a Hobby/model shop.  The most
time consuming part was laying out the pin spacing.  Careful measuring is
importent if one wants the form to fit the socket.  Pins and fiberglass
base was then epoxyed together.  Tools used were hack saw. files, metal
shears and drill bits, and some ingenuity.  Plan on taking some pictures
and such when I get my scanner and other computer going.
Also I do seem to remember on Kees web page or notes there was someone who
described how he made his forms that looked really good. He used a lathe
to turn the parts.  I have two lathes but hand made mine.  By the time one
sets the tooling up I could make several forms by hand.

Message-ID: <3DC94A8D.FEA50654@3-cities.com>

Hi,  I think the Ocean State forms are high quality,  based on my
impression that they are the ones made by Jim Fred.  I bought quite a
few of the SW-3 coil forms directly from him,  more or less the same
price,  depending on how many you buy.  The description in OS catalog
makes me think they are the same quality.  His are overkill,  because
they are canvas reinforced phenolic thoughout with staked-in pins.  I
resorted to his because for the SW-3,  they have the small recessed
channel at the bottom for the tickler coil and it's difficult to find
the unusual 6 pin type that the SW-3 uses,  non-uniform pin spacing.
Dan.

Jeff,  were these the CF 4 type at $6.90 each?  Or did you get some lesser type from
Ocean State (not Oceanside?),  Dan

I use a variation of Helmut's technique.   I mount the socket in a vice 
or chassis hole.  I put the pins into the socket -- they should be cut 
to stick up maybe 1/2" to 5/8" or so.   The holes in the base piece 
(fiberglass, etc.) are laid out not quite so carefully and drilled with 
clearance so they'll go on -- minor adjustments can be made if  
necessary with a file.   I use this base to press a piece of wax paper 
over the pins and down to the socket, then drip parafin wax from a 
candle to cover the wax paper.   Then put the base piece on top of 
the wax while it's still soft; ideally the wax does not come up into the 
holes but does seal them.   

The wax paper keeps the wax out of your socket; the parafin *really* 
seals things so no epoxy runs down there.

Now I pour epoxy onto the base piece, securing the pins and forming 
a permanent plug assembly.   You can do this with the form in place 
too -- that's the strongest.  Or just fasten the pins to the base and 
attach the form in a separate step.   I try to wind up with 1/4" or more 
of epoxy above the base; have never had a plug made by this 
technique give a problem.

Variation:  Forget the base piece altogether and just use 3/8" of 
epoxy above the parafin.   In this case I'd put the form on at the same 
time and alignment of the form with the socket will have to be 
maintained while the epoxy sets.   The wax will do that, if you use 
enough of it.

I always sand all the surfaces the epoxy will bond to with coarse 
sandpaper first.

Yes. the forms were  CF-5 that I got.  Apparently that is the best offer.
Walt that is a good idea. Ill try  your coil form build idea on the next set

Here is an idea:

To transfer the 5 pin base outline for the coil forms, to make a base for
your new coil forms. Take a unused or a
plug that has all the pin holes open. Old 807 tube base with the innards
removed will do fine. Hold  the plug steady  with pins down, on the material
that you want to mark. Using a pin vise with a number 40 or so drill bit in
the vise, transfer the pin outline thru the pins to the material and turn
the pin vise a few times to mark the pattern outline. Do this to all 5 pins
without moving the 5 pin base. Drill out the marked holes to the desired
size.
If you are lucky to have a set of transfer punches that is better.
Works for me.

I picked up three input and two output 175 khz IF NOS transformers at a

it be to sharp for AM reception?

I have never found a type K Helm. When I built my 56 Novice special, I had
to home-brew a type K with a unknown mfg.dial, two 1/4"bushings and rubber
grommet. A 1/4" shaft with a tight fitting grommet rides on the perimeter of
the dial. Has been working great without slipping since I built the rcvr in
the 90s.

Hi Scott
I love my Novice Special. Sure it works fine on CW, SSB and has speaker
volume. Regens are a skill like sailing - don't give up. For two tubes, RF
and AF, it's incredible what you can receive. My first SWL/Novice receiver
was a Explorair regen kit.

Hi Bob,  Great photo's of your Novice Special.  I recently bought a "M"
dial, which is just like the "K", but a 5" diameter instead of 3 1/2", for
the purpose of building that receiver.    How is the performance of the
receiver?  Do you use it on cw?  Could you
:^)   I guess it comes down to "was it worth building"?

Hi Helm,
Let me look what I have. I am never going to use all the stuff I have salted
away. (corrosion free salt)
Yes - lets push Kees to get some simpler designs on the page. Mine is a very
close replica of the June 1956 QST article and was the staple for the ARRL
"How to Become a Radio Amateur" publication for many years.

Ok. I've lower my sights, does someone have just the 3 1/2in. dial?
Manufacturer unimportant.  Please state price, condx, etc.

Nice pair of regens you guys built.  Me too, mine's in the chassis stage
and still looking for a part or two.  HBR on hold again.  Interesting,
mention some type of vernier drive mechanism and the next thing that pops
up is regenerative radios.

I wonder if Kee's would publish some pics on his web page?  They are
homebrew receivers (HBR 1's or 2's?).  Some people who want to build the
HBR-16 ask if there's something they could build since they don't have any
experence.  A simple regen could be good.

As an added thought about my dial.  Could some mike out the thickness of
their dial.  As a last resort I'd cut and etch one
up in my lathe.

Helm.  WB2ADT

Helm,

I think I have just the dial dart of a Type K dial. I will have to dig 
through some boxes to find it, though. It was in good condition but missing 
the pinch drive part. 

Also have lots of other stuff for the "Novice Special" - tubes, sockets, 
power supply stuff, small parts like disc ceramics and variable caps, bases 
from old tubes for coil forms, etc.  

Will let you know what I find in the "dial box".

Hello Lorne
The original design was in QST June 1956.
It was run in ARRL's "How to Become a Radio Amateur" from 1958 through my
1967 printing and maybe longer.
The design was also used in RCA Ham Tips Feb., 1959. The only changes were
adding a volume control and band coil sources.

Bob, I am impressed with your novice special RX.
I have built several regens but have had poor results.
I guess after having built  two HBR's and working on the third
my expectations may have been too high.
I have built  one with a single 6SN7 and also a couple solid
state ones. I was especially disappointed in the SS types.
I have tried finding the circuit diagram for the 56 novice
special and am unable to do so. I do not have the QST issue and
none of the handbooks I have in that area show it.
Is there any where that I might get a diagram off the internet?

Tnx es 73

The article was by Don Mix, W1TS (SK) who was quite a guy. (See "Ivory Tower 
Confessions" and "Last Voyage of the Bowdoin", among other QST stories). 
Longtime ARRL Hq staffer, veteran of Arctic expeditions from spark days 
(Sleepless Wonder of 1TS) and quintessential Yankee. Though I never met or 
worked him, I consider him one of my Elmers due to his writings' influence on 
both my amateur and professional careers.

In researching the "Novice Special", he found that (for him, anyway) the 
small "hot" RF pentodes were poor performers but a big audio tube like the 
6AQ5 did a great job.

There was also a followup article about a 6BA7 converter to go in front of 
the Novice Special, thereby creating a three tube Regenerodyne (though the 
term was not used in any of the articles). Also a 25 watt 80 meter 
transmitter using a 6DQ6. All working from a single power supply. I wonder if 
anyone actually duplicated the entire setup.

The ARRL "How to Become a Radio Amateur" 1967 shows a companion one tube
crystal-controlled converter (6AN8A) for covering 20-15-10m for the Novice
Special Receiver. There is also a companion one tube (6DQ6A) transmitter.
RCA Ham Tips 2/59 mates the rcvr design with a 6AU6vfo/5763pa transmitter
for the portable "Weekend Special". I have one - works great.

There was also a followup article about a 6BA7 converter to go in front of
the Novice Special, thereby creating a three tube Regenerodyne (though the
term was not used in any of the articles). Also a 25 watt 80 meter
transmitter using a 6DQ6. All working from a single power supply. I wonder
if
anyone actually duplicated the entire setup.

Lorne,

Fine on starting your third HBR. I am thinking to start to build my second.
What are you using for the IF transformers?
Three HBR's, what are you going to do with them?
Did you get the SSB xmtr finished and working?
Jeff

I believe they would be just about right for communications type AM. I
recently converted a HBR-11 for AM use using a 2762 Kc first IF and 262 Kc
second IF. It was too wide for use in anything but a sparsely occupied band.

Thanks Darrell,
I guess if I wanted to tighten it up, I could add some sort of a
q-multiplier circuit for cw.

Hello Helm,
Have you found a dial?
I searched but had not luck. I am still unpacking. I have another area
to look in
Can you really etch a number scale on metal?. I need to replicate a
dial that has raised numbers and increments. Would you use copper
and resist decals?

Ok. I've lower my sights, does someone have just the 3 1/2in. dial?
Manufacturer unimportant.  Please state price, condx, etc.

Nice pair of regens you guys built.  Me too, mine's in the chassis stage
and still looking for a part or two.  HBR on hold again.  Interesting,
mention some type of vernier drive mechanism and the next thing that pops
up is regenerative radios.

I wonder if Kee's would publish some pics on his web page?  They are
homebrew receivers (HBR 1's or 2's?).  Some people who want to build the
HBR-16 ask if there's something they could build since they don't have any
experence.  A simple regen could be good.

As an added thought about my dial.  Could some mike out the thickness of
their dial.  As a last resort I'd cut and etch one
up in my lathe.

Regards,
Helm.  WB2ADT

The way I have made up graduated metal dials is with a lathe.
In a nutshell what one does is chuck up the stock and cut the dial to
size.  Then bore a 1/4 inch hole dead center.  I then re-chuck it into the
spindle bore of the lathe.  Using the tool holder with a screw cutting
tool held perpendicular to the piece I lower in into place at a depth of
about .01 inch.  I then move the tool holder out towards the perimeter of
the dial and there you have a beautifully cut "etching".  One then
continues around the dial until its finished.  Of course one also need to
calibrate the spindle in degrees and some sort of clamp has to be devised
to lock the dial in place as the tool is drawn thru.  Or if you got the
bucks or knowhow to made a degree wheel that is the easiest and most
accurate.  Small number dies are used for markings.  I then fill the
marking in with of all things, crayons.  Rub into the etching and then
wipe off excess.  I've used all sorts of paints and application techniques
but so far this is the nicest I've seen.  Try it on an old knob some
time.
There is a bit more to than that but that's the basics.  It's actually
quite easy.  Most machine work is unless one's a real duffer.  It can be
quit fun.  Why with a good engine lathe and some welding equipment you
could build just about anything.

Sounds like you can make very handsome dials. I would love to see one. You
must use quite heavy metal to not get warp distortions when using small
number dies for markings? I assume the numbers are stamped?

The first three I make 20 years ago or so were crap.  I finally got the
procedure down after several trys.  The stock I use is usually .015 thick.
Not too big not to small.  Stay away from stainless and coffee can tins.
Metals are very mallable, moreso than one would think.  The dies must be
sharp and the impression is transfered with the piece over a hard flat
surface.   I use a granite surface plate but have used cast iron also.
One taps the impression in lightly(one straight tap).  This is not lop
hammer stuff.  I have a varity of hammers in the shop and the one I use the most for
everything is a 3 oz. ballpeen. We're not making I-beams or horseshoes
here. The last dial I made is sitting on a regen receiver I made for my
brother last Christmas.  Unless I get up enough energy, I probably won't
be doing to much machine work.  Right now I'm finishing off the wiring on
a one tube blooper.  Hope to have some pics and the silly story behind it
at the end of the week.
