Making
"Homemade" Tools for your hobby workshop - Ain't Hard!
Whether its a simple sanding block, or something a bit more
complicated. You may
already have most of what's required to make the item, amid your scrap parts -
maybe. for example.
If not, check out - Flea Markets, Electronics' Parts Suppliers and local - Auctions & Sales, for reduced
priced - used tools and old parts and items, or even Craft Stores = for example. You'd be surprised
what
you'll find for pennies on the dollar, that can be converted or abused &
heavily used - battery powered - toys.

The
Hot Wire - Foam Cutter
Tap Drawing To
Enlarge
This thing, easily cuts all types of Styrofoam ( Blocks & Sheets
) into any shape or form desired.
I designed my system to have 2 - Wands, meaning a "Large Bow" = for
cutting large foam hulls, plus a smaller
"Hand Wand" for smaller cutting tasks. Like - for example, carving
a stern - tunnel into the foam core of a models hull. (( WARNING
.... This Is Not A Toy! )) DANGEROUS TO OPERATE!! The Hot Wire
gets - RED HOT and can easily - Burn You .... So
be careful using this device and be sure any helpers - assisting
you, are aware of the dangers too!
HOT WIRE .... Parts List -
#1 ... Ac or Dc - Model Train Transformer
( 12 to 18 volts output at 2 - 4 Amps. ) Most any train
transformer will do, including similar Power Transformers with variable Ac or
Dc - outputs. Purchased or Scrapped from your parts, that meet required Voltage & Amps.
#2 ... Dowel Wood - Rods = ( Handle
& Bow ) making parts of 1/4" & 3/4" Dia.. Rods
NOTE ... Make the Bow and Hand Wand to the widths you require,
to cut any size foam. Usually a
ni-chrome wire stretched between
the bow - ends, that's 2 1/2 feet wide - at most. Works fine for most any
job you'll use this system for.
As for the
Hand Wand, it should be a U-shaped - short piece of nichrome wire, about 4
inches in length = between the forks of the wand. Then before
use, shape the wire to desired shapes for carving jobs, then turn the power - On
and gently start carving.
#3 ... Nichrome Wire Sources = Hobby Shops or
Hobby Suppliers = A resistor wire that heats up, to cut or melt
Styrofoam.
#4 ... Two Scrap pieces of Brass Tubing, used
to make - heat insulators to avoid the wood dowel rods from being burned by the
nichrome wire.
INSTRUCTIONS
FOR USE ....... Set your Transformers - voltage settings, at the lowest voltage setting - First.
Then turn the system - On. Slowly increase the voltage until the
"Nichrome Wire" starts to smoke and heat up. Testing
the heat settings on a piece of scrap foam - First, before you start cutting
anything, adjusting the voltage setting accordingly. WARNING
.... Never set the voltage higher than is needed to cut your
foam, Slow & Smoothly. The wire can be easily - Burn Out
and will break apart and easily injure you or someone else!

Homemade
"Paint Bottle - Shaker!
Powered by 9
volt or AA = Battery Pack, or Small DC Power Supply
Tap Drawing To
Enlarge
This Sucker - Works! Its
cheap and easily mixes small bottles of paint.
Just open the bottle and add a few drops of the proper - Paint
Thinner. Then, tighten the lid and drop the bottle ( Upside
Down ), into the shaker. Then - Flip the Switch and wait a few minuets
for the paint to re-mix and its ready to use again! If you use a deeper - Tin Can,
when making your "Paint
Shaker, it will stir - Two
Bottles ... At Once. Just wait a few extra minuets for all paints
to become - well shaken, before their used on a project and check the paints - consistency
too. And by the way, make sure the
Tin Can - used to build your - shaker, is large enough to fit - ALL
SIZES" of paint bottles, which you prefer using, or will use ...... "OK!"
The Battery needs - a long
very flexible wire to allow it to be mounted elsewhere on the table, so make the
wires length - doesn;t effect the shaker or stiffen its
motions. So make the wires as long as you need, to be lounted
elsewhere on your bench. And the "Washer", is attached to
the motors - drive shaft, so it wobbles ( drill an Offset Hole into it ), so it
shakes the whole thing..... "The more it wobbles, the better it shakes the
Paint!"
Use CA - Super Glue, to mount the motor = to the bottom of the can, or make a
metal strap to clamp the motor to the can, if you wish, but its gotta be
=TIGHT! And you'll need a couple of small ( 4 ) "Wood Eye
Screws" to mount the can and battery on your
workbench. And then just hang the cans = two rubber
bands, on two of the eye screws and the battery and wire on the othere, so the
can hangs loose - by itself. Then add the bottles of
paint - to be mixed and throw the switch and watcher - Sh-Sh-Sh-A-a-a-a-k!
Paint Shaker - Parts List
#1 ... (4) AA Batteries, or a 9
Volt Battery, or use a Junked Out = Small DC - Power Supply = 6 to 12 volt
output. And wire the power supply into the switch, in place of
the battery system!
#2 ... AA Battery Pack = ( Radio Shack )
plastic Pack - made to hold 4 - AA Batteries.
#3 ... Mini On/Off - Toggle Switch.
#4 ... ( 3 feet ) of small insulated - Twin
Lead - stranded = Speaker Wire.
#5 ... Small 12 Volt DC Motor. ( Radio
Shack )
#6 ... ( 1 ) Old FLAT - WASHER, to make the
Vibrator. Drill an Off-set
Hole in the washer = Way Off Center, but the same diameter as the motors - drive
shaft diameter is.
Then use a couple of drops of CA Glue to mountit on the shaft of the motor -
firmly Just make sure the washer spins freely and doesn't
bump the can as it spins around on the motor's drive shaft.
That will insure a good vibration effect is provided to the can and the paints
inside it, as their mixed or remixed.
#7 ... ( 1 ) Tin Can ( Small - But Long
Enough ) to fit two bottles of paint - inside the can = One On Top of the Other.
(
NOTE ... I used an old Hair Spray Can - for mine! )
#8 ... ( 2 ) Heavy Duty -
Rubber Bands. Used to mount the shaker on your workbench
#9 ... ( 4 ) Wood
Eye Screws - Small ones, to screw into the bench, to hang the paint shaker - On.
Plus the Battery Pack too, in a nearby location.

Build
A Model - Transport & Launcher
This idea, is mainly for
"Older
& Disabled" Modelers - like myself, needing
assistance in getting models from the vehicle to the pond and then = launched. And
this idea builds - fairly easy, and works great for anyone that needs to save
their backs, from a lot of aches & pains! NOTE ....
A common Two Wheel - Cargo Dolly, may be a bit heavy, but can work also, if
provide a couple of helpful additions. Like for example, a
wooden platform to widen its base to fit the models - hauled on
it. Straps of added arms, to support or hang the tool box -
similar the drawings shown below - shows as an example.
Remember, you have a radio ( 's ), plus tools and support equipment to carry
too, besides the boat & barges!
Tap Drawing To Enlarge
Built from PVC Plastic Pipe (
Dia. of PVC Pipe - Is Your Choice ), but I'd suggest at least 3/4" diameter
pipe for the smallest diameter of pipe - used. Along with a pair of Old Lawnmower
wheels and a threaded rod for their axles, with a couple of nuts to hold them.
And this could also be remodeled or fashioned out of an old metal Two - Wheel
"Hand Dolly" too. And should "Break- Down" to
fit inside your vehicle. Some builders may want to use a small
pair of soft wheels ( air inflated tires ) , to soften
the ride on their models, which is also - a fine idea too. When transporting
boats - long distances, from a vehicle to the lake or at events, you'll be glad
you built one of these = They sure save
your back!
Note the "Handle Bars" are
adjustable in height, and also how their mounted ( IN Either Direction ) on
top of the two vertical back supports of the launcher. They
can be positioned either way, to assist in balancing a model, when its being
launched into the water or just hauled on the transport/launcher.
Just remember
to remove your - Tool Box, prior to launching the model, unless ya like Soggy
Tools!
Parts List -
#1 ... Several lengths of
1" - 1 1/2" to 2" Diameter - PVC Pipe ( Requires 2 Sizes of pipe
- One Fitting into The Other - for the adjustable - handles ), plus Elbows, T's and End Caps.
#2 ... 30" Length of
"Threaded Rod"
for the Axle, plus ( 6 ) Nuts and ( 6 ) Washers for wheel spacers
#3 ... ( 2 ) Old Lawn Mower -
Wheels ...... Option = "Small
Air Inflated Tires" to soften bumps!
#4 ... Several Large
- Cotter
Pins, plus a short length of Rope, to tie the Cotter Pins - to the frame to avoid loosing
them, when launching boats.
#5 ... Short Piece of Carpet
... Glue around frame area of Legs on the Launcher.
Avoids damage to models, as their
launched, transported and retrieved.
#6 ... ADDED
OPTION = Tool Box,
a small plastic tool box to hold r/c radios, batteries, parts and tools.

Building
A Dry-dock
Display / Carrier
Designed to
work with the above - Transport / Launcher
Tap Drawing To Enlarge
The Dry-Dock & Display /
Carrier, Is
designed to be used with the Above - Boat Launcher Cart. Very simple to make
from solid 1 inch thick - Pine Lumber, cut to Lengths & Widths to suit the models size. This even
handles Deep- V
hulls, as well as Flat Bottom Boats, when slight changes are made to adjusted it
to suit any type of boat, by using wedge fittings for V-
hulls. These are pegged
into the bottom plate of the carrier / dry-dock, and removable if needed.
Makes a great display too, when a few fancy fittings are included to make it
look realistic. For average sized boats - such
as 10 to 35 inches in length - for example, I use 1 by 4 sides and 1 by 6 - or 1
by 10 or 12 boards for the bottom plate, sealed and stained or painted.
Cheap, easy to make and lasts a long time, this is a great looking model transport /
carrier & display
for any model. And best of all, it also provides
some side-hull protection against damage and could even be used to carry and haul
a number of barges - stacked one atop the another.... "Hey, how do ya think
I haul all my barges - around!"
I'll Add More - Later, so check back Often!
