Old School Model Works RAVEN Construction Manual page 3

• T-Pins
• Waxed paper
• Building board
• 2-part epoxy (15 or 30 minute), brushes and mixing sticks
• Wood adhesives of your choice. We use medium viscosity CA
(cyanoacrylate) , but aliphatic resin and/or carpenter's glues (used
correctly) will work just as well and give longer working time.
• Thin CA for attaching the included hinges
• A spray bottle of glass cleaner (with ammonia)
We advise the following:
Closely inspect the supplied laser cut parts for damage. If you fi nd any
damaged or missing parts, contact us (not your dealer) immediately.
When removing the laser cut parts from their sheets, you'll notice
the parts are held in place by several small "tabs". These tabs
are uncut pieces of wood and can sometimes make it diffi cult to
remove a part. Rather than breaking and/or splintering the wood
by forcing out the part, we recommend removing any laser cut
parts from their sheets by using a hobby knife with a sharp blade.
A quick cut of the tab will allow the piece to be removed with no
damage. Sand any tab remainders fl ush with the part so there will
be no problem aligning them later.
It's best to not remove parts from their sheets until they are needed.
Refer to Appendix A of this manual as a reference to what all the
laser cut parts look like and are called.
You'll notice a check box next to each step. Check these off as you
go along so you don't miss a step. Some steps (building the wing)
have two boxes - this means the step will be done twice - once now
and once later (when told to repeat) for each wing half, for instance.
There could be a step or two which leaves you a bit puzzled. If this
happens, step back and study the photo(s) for that step - both in
this manual and online.
All photos shown in this manual are of different Raven prototypes.
Several pieces may have changed slightly with improvements
we've made so parts may look a little different in some steps.
Online Supplementary Photos
We realize that the smaller black-and-
white photos in this manual might not
show some of the steps as clearly as you
might want. So we've anticipated this
and made these photos available on our

InstaCAddy
Throughout this manual, you'll see
photos with our InstaCAddy on the
bench. This is a unique collection of
Bob Smith C/A glues, accelerator,
and pipettes. What makes this
special is the box, as it has cutouts
that make it the perfect tool to hold
everything in one spot - and the
glue won't spill! If you're needing C/A, consider our InstaCAddy!
Construction Manual
IF YOU READ NOTHING ELSE
IN THIS MANUAL, PLEASE
READ THESE FIVE POINTS.
#1 - We've done everything we can to make the Raven a
fun and easy to assemble kit. That being said, THIS IS NOT
A BEGINNER KIT. If you've never built this type of balsa
kit before, you will probably experience many challenges
along the way. This manual is not written for beginners - it is
assumed that the builder has the skills and techniques needed
for these steps.
#2 - PLYWOOD HAS SLIGHT BOWS IN IT 93.48% OF THE
TIME. We don't like it, but that's the way plywood is. Because
of this, we engineered the Raven to eliminate these warps
whenever possible - we'll make recommendations on how to
overcome them as we go along.
#3 - BALSA HAS SLIGHT BOWS IN IT 81.53% OF THE TIME.
We don't like it, but that's the way balsa is. We'll make
recommendations on how to overcome them as we go along.
#4 - It is very important that you assemble the Raven in
the order described. Skipping forward in the steps could
leave you without the proper lengths of wood to fi nish
the kit. We've included enough wood to easily complete
this kit, but you must take care to properly measure and
not waste wood when cutting.
5 - Save ALL of the scrap wood as you build - the ends of
sticks, the left over sheets, etc. You will use some of this
in assembly, and can maybe use pieces if you need repairs.
If you take your time, take the time to understand steps,
and make the effort to do good work, it will certainly show
Whether you're hinging,
mounting, gluing, sanding,
soldering
chances are we've got a
video tip to make the task
easier.
OSMW has created a series
of videos to help you not
only build your aircraft, but build
it better. These Bright Idea videos
can come in handy for some of the
following steps.
