"Low Profile Vise"
Photo shows the Rocking Corner Test, now that I have the finish I was looking for.
Passed the Fingernail Test also.
The Low Profile Vise is a winner !

Tom,
WOW! I never knew that.
Thank you!

Larry,
Google "Anodizing Aluminum Kits." You can do it yourself at home.

Hi Larry,
no ignorance at all.
The "red" is anodized aluminum and is part of the vise from the
manufacturer.

Photos show various set ups.
Object is to test the new vise.
Block is 1 1/2" by 2" by 4 1/4".
Block was rough cut in my Proxxon Chop Saw.

just to display my absolute ignorance - to you and the group - where do you get the red metal (aluminum)?

Photo shows an improved set up to check for square.
Square is a L.S. Starrett # 20 4 1/2" .
Hope my work turns out as well.

Glad to know that you did not misunderstand me. Please let me know how it goes.
I enjoyed making the SG-8 work. I checked its frequency accuracy with my FT-950 and it worked "as specified". LOL. (Heath Company never gave any calibration accuracy or stability in their specs, so you get whatever it gives). I had soldered a small piece of 6" long wire to the center of the crappy audio connector that is used at the RF output point. I got sufficiently strong signal that kicked S9 + 40dB on my FT-950.
I do not remember using my SG-8 ever after restoring because I never really needed it. I restored it for the fun of doing it.

Thanks Prasad -
Even though I am familiar with tube equipment and high voltages, the warning is appreciated and always safe to give someone a reminder even if you think they do already know.
I'm planning on replacing the electrolytics and thanks for the idea about those diodes too - I'll check them.
My main reason in asking the question was to learn the proper ways to couple the signal generator into equipment.
I know there are various things you can do with a VFO that will distort or cut-off it's signal, etc.
I didn't know if there were similar circumstances for a signal generator, by which if I unknowingly connected it in a certain way, it would not work right, or the signal would not be injected properly into the equipment.

Tim,
One word of caution, SG-8 signal generator has high DC voltage inside about 150 Volts. Please take abundant care as this voltage can be dangerous or even lethal if you make any accidental contact. I am assuming that you are not familiar with tube apparatus. My apologies if I am wrong in making this assumption.

Tim,
I would download manuals or at least circuit diagram. Google the model and you will quickly find them on the Internet. Then check for voltages to match them as given in the manual. If I see any missing voltage I would then look for the culprit. These signal generators are very simple. If you have access to a scope you would localize the fault quickly.
I own a SG-8. My first action was replace all electrolytic capacitors. There are not too many of them. I think I also replaced the rectifier diode(s) - type IN4007. SG-8 worked fine when I turned it ON after the replacements of electrolytics and diodes. I had applied a small drop of switch cleaning oil from Radio Shack. SG-8 has an audio oscillator which is used to modulate the RF signal.

Hi everyone -
I obtained a couple of Heathkit signal generators, which appear not to work, even after some DeOxit.
One is an IG-102, the other is an SG-8
Right now, I'm just looking for some basic guidance on workable methods to test.
I know I should be able to receive them using a local receiver, but I wasn't sure exactly how to couple them to a receiver, etc

Make sure that you turn on the audio modulation when trying to receive
the signal generator on a radio.
If you have audio modulation off all you'll hear is a "Dead" spot on the
frequency of the generator. With
the audio modulation on you should hear a 400-600Hz tone.
Most of these signal generators are pretty solid simple circuits. I was
just looking into my old HK SG
yesterday and there are 3 Electrolytic capacitors. While these are
probably good I'll probably go ahead and
replace them soon since they are the most likely failure items in these
units.
The SG8 does have a selenium rectifier that is an accident waiting to
happen. It can be replaced with a
1N4001 type diode and a ~50 Ohm, 5 watt resistor in series to match the
loss of the selenium unit.
Search for a web site called Boat Anchor Manual Archive on the web and
you can download the manual
from them for free.
