If the wing and rudder glue joints are going to be tight and clean the laser cut 'wedges lines will have to be squared up.
On the left you can see the center alignment line burned into the main wing piece.
I found in interesting that the Estes instructions showed the Great Planes Easy Touch sanding block in their illustrations. This is the only sanding block I use.
The inset picture shows another reason for cleaning up the laser cut balsa. Sometimes you find a rough or uneven edge as if the laser were "chattering" down the cut line. Personally, I think glue joints might be weaker on burnt wood.
Not terribly shocked about the Great Planes sanding block - Great Planes and Estes are both Hobbico companies.
ReplyDeleteGood point Chris!
DeleteMaybe they should suggest that sanding block in their instructions. It's that good of a tool.
Man, remember the days when we sat down with a new #11 blade and cut all of those parts out one at a time? Remember the Guillows kits with numerous tiny little parts that wanted to split along the grain (and some of the hardest balsa)? We thought we had it made when kits came die-crunched.
ReplyDeleteNow we have laser cutting and even complicated shapes 3D printed. Such luxury!
Hi Tim,
DeleteI remember cutting out all the balsa for the Estes Orbital Transport. Even the Guillow's kits have laser cut parts now!
New modeler's don't know how easy they have it. I've seen forum posts where somebody posts a picture of a ARTF rocket and says: "Look what I just made!"
I noticed the illustrations feature the Great Planes sanding tool also, which I think works well only if you are familiar with that product. Is it available overseas? I wonder?
ReplyDeleteHi Anonymous,
DeleteThe sanding block is available from Tower Hobbies, they have a currency converter so I'd assume they ship overseas: http://www3.towerhobbies.com/cgi-bin/wti0095p?FVSEARCH=easy+sander
