Sanding Laser Cut Fin Edges (2011-12-12)These are the fins from the Quest Tomahawk kit. This laser burn was dark because the fin stock was a very stiff balsa. To the right is the fin sheet facing up as it was cut. The black burnt lines ... [Read More]
TIP: Small Padded Sanding (2012-10-14)The Centuri Satellite 62SL is pretty small. I could have simply folded up a piece of sandpaper to get in the tight spots. Sometimes the sharp crease in the sandpaper cuts "ruts" into the finish. ... [Read More]
New Sanding Block! (2012-11-13)Oh Boy! A new tool! This was picked up for $9.95 at my local hobby store. I've had my eye on this one for a while. Midwest makes some great building accessories and I have high hopes for this ... [Read More]

Wet Sanding Thoughts (2013-02-14)I've read a few forum posts where new builders talked about wet sanding. That piece of 400 grit (wet/dry) sandpaper in the glass of water is only about 2" X 4" in size. That one piece should be ... [Read More]
Touch-Ups after Sanding TIP (2014-08-02)Did you ever sand off an edge of a white undercoat? This Little Green Man prototype had a glue blob on one of the toes. After sanding it down, the white cover paint was removed. I didn't want to ... [Read More]

Wet Sanding Part 2 (2015-02-05)When wet sanding, you don't have to go all the way down to the wood surface. Just "knock down" the surface imperfections. Take the sandpaper out of the water and shake off the excess. Keep a paper ... [Read More]
Wet Sanding Part 3 (2015-02-06)These new paint formulations can drive you nuts! Currently I'm using Rustoleum 2X painter's Touch. It's got a LOT of pigment in it and can cover with fewer coats. That thicker pigment can clog up ... [Read More]
TIP: Sanding In A Tight Angle (2015-11-18)Normally I would sand a rounded fillet area with sandpaper over a Q-tip for a cushion. If you have a very tight angle to sand, the Q-tip might be too wide. Here's how to get sandpaper into a tight ... [Read More]
Spot Sand and Polish TIP (2016-03-04)Sometimes after the paint dries you'll find a raised speck of dust or a small blob of paint. Sure, you could sand it all down and shoot it a second time, but you run the risk of it happening again. ... [Read More]

Tools - The Essentials, Sanding Blocks Part 3 (2019-10-31)After some sanding you should check for build-up on the sandpaper. These little nubs of filler/primer can get large enough to scar your balsa when sanding! On the right is a soft brass wire brush ... [Read More]
Tools - The Essentials, New Cheaper Sandpaper Roll! (2019-11-15)I mentioned earlier how much I use the OOP Great Planes Easy Sander sanding block. The sandpaper is sticky, no clamping! A problem - Great Planes sandpaper rolls are expensive and aren't available ... [Read More]
