[Boatanchors] Radio Shop Glues and Making Penetrating Epoxy

[BLIMPY]

Pentrating Epoxy

To thin epoxy - say to saturate wood, paper, or seal same- dilute with 
ACETONE.

Acetone is also the solvent of choice to get the crap off yourself  ( ditto 
super-glue when you glue yourself together)
Alcohol being a polar solvent.. won't do the job.

For example.. say  you want to make a cheap transmitter coil form from a 
toilet paper roll - or paper tape core.

Get some nice   2 part "liquid" epoxy at your local ACE hardware store.  Mix 
qty needed, then thin with actetone. Apply with cheap small brush and allow 
to soak in as needed,.  This will seal the material, and make it 
considerably stronger, not to mention moisture proof..
( try this on some really rotten wood to see how much stronger it makes 
things ! )


Barge Cement  - Multi-Purpose Glue for Porous Materials

A cheap multi-purpose glue which works well on Porous Meterials is Barge 
Cement.  This works on ceramic, paper, leather, and most plastics.
It is solvent based, and will eat into plastic.. so not for cosmetic 
repairs.  This is glorified rubber cement. But far better.
It will bond porous and non porous materials together...such as cloth to 
metal.

Bonding to Metal

Silicone rubber will attach almost all items...to metal chassis... except 
Teflon.

Say you want to re-cap a vintage radio using " Jap Cap" electrolytics - 
leaving the old cans in place .  Good practice often dictates that the new 
caps not be left hanging by thier leads alone.   A small dab of silicone 
rubber will attach the capacitor to the underside or side of the chassis 
securely.  Easily removeable without a trace.

Small relays, ceramic stand-offs and other items can also be added without 
drilling any holes.   Peel off, or use razor blade to remove.
Gravity wont defeat this stuff.  Cannot be removed from porous materials 
like wood, unglazed ceramic, cloth, rubber.

Making Custom Dial Belts.

Neoperene O-rings are available in any size at hardware and 
tractor/hydraulic parts stores.
You can make custom dial belts by cutting the O-ring to size ( slightly 
small for tension - they stretch) .
Cut with a sharp razor blade.
Cut Square !

End glue with Super Glue ( glue in place - no need to dissasemble ! )  and 
bingo !
This bond is as strong as the rest of the O-ring.  Use fingers or needle 
nose pliers as needed. Eyeball is good enough.

Even works in motorized Zeniths !

My guess is it would work on that damn gazillion dollar Hallicrafters RCVR.

Styrene Aircraft Model Cement

The model cement used on plastic car models... will also work on porous 
material... like the ferrite antenna.
Dries very quickly. Stinks.
