"Newbie" TIP: tracing kit parts
SuperDave Wed Sep 14, 2011 2:55 pm
When doing a kit it's very handy to make a pattern of the parts when they are removed from the balsa sheet that contains them. Patterning the balsa sheet gives a dimensionally smaller part from which to make a copy.
Should you ever need a spare part then you have an accurate pattern from which to make the part.
Ah, the wisdom of the aged!

BTW: This in no way will infringe on a patent unless to make a profit doing it. Then it's infringment time in court

Yes, beez, it is. I've done it more times that I care to remember.
I've done it with my new "Lil' Toot" bipe which now complety assembled and ready for finish largely due to the use of epoxy and medium CA+ cement.
Prior to assembly I lightly sanded and rounded the individual balsa and plywood parts test- fitting them as I sanded.
Having the aforementioned patterns available is an assurance that the plane will live a long and useful service life.

yep, its definitly helpful. what grade of sand paper do you use to sand it? 280?

it is a very good idea but if you have a guillows they include patterns of all parts on the plan as if they want you to build another model from it
i suppose it is incase you break a part from their brittle wood.

Or of those lacking in ambition. Guillow's also offer spare parts for their kits.

oh cool i didnt know that.
i have only built a few in my whole life and i only build from the plans without there instructions.
i find it easier my way.

For those with prior modeling experience that very often works well. HOWEVER I always "skim" the provided instructions first as "twists" may have been added.
with my current "Toot" there is a sheet descibing the differences between the current "laser-cut" version and the old, more than you might think. The use of CA+ cement is a good example.

beez:
I use six GRITS (not grades) ranging from 80 (course) to 400 (ultra-fine) depending on the task to be accomplished. Roughing out shapes is best done with course and finish work with fine with the intermediate grits used between them.
Visit a hardware store to see and feel tne actual differences.

great, pretty much have all the different grades of sanding paper in my workshop, one thing less
on the shopping list.

I very carefully extract pieces from lazer cut sheet,,just to save those patterns.
I recently used one cut pattern to create a test elevator,,for testing covering shrinkage and warp, paint reaction, color match, ect.

.
As I stated CZ, copying the balsa sheet gives a dimensionally smaller pattern from which to make a copy. Even if patternig the actual part, any excess material may be sanded way which is impossible in the scenario that you propose.
OR, how does one make an undersized part larger?

How wide is a lazer cut?? 1/2 millimeter??. It looks about that size I guess.
If you trace your pattern, then cut to the outside of your line,,it should be reeealy close. Just cutting to the outside of the pattern line should allow you to "sand in".

That much really should not make much difference on a sport model just try it and see.

'tall depends how how prescisely you wish new part to fit. Sloppy builders don't really care; I''n not a "sloppy builder".
Is that a psycological disorder like being anal retentive?

I am not a sloppy builder either just ask my flying buddies.
But 1/2 a millilimeter is about 1/80 of an inch and on a sport model will not make a noticable difference.

It went from tracing parts to anal retentive, lol.
