All the open ends of the body tubes got a strengthening coat of CA.Lately I've been setting a drop of CA on a scrap piece of cardstock. A Q-Tip is dipped in the CA. While it's still wet, the CA is rolled around the end of the body tube.
This is a cleaner, easier way of putting an even coat of CA around a tube end, as opposed to applying it right out of the bottle.
Less CA is used and there's no chance of drips running down the inside of the tube. You do use a few Q-Tips on a model like this with a lot of body tubes.
The clear plastic fins were stacked and gang sanded with 150 grit sandpaper on a block.220 grit followed, then 400 grit.
A little plastic had rolled over the sides. I didn't want to sand that off and run the risk of marring the clear side. I used the side of my X-Acto knife to lightly scrape and remove the "flash" from the edges.
One thing I did for a long time on my scratch built crayon rockets was place 2 inch wide packing tape on each side on the clear polycarbonate fins. Done carefully you can not see the seams at a distance and it kept the fins pretty scratch free. When the tape was scraped up, I peeled it off and place a new layer. Those fins look small enough they might fit across one two inch piece of tape making a clean covering of it.
ReplyDeleteHi Jeff,
ReplyDeleteThat is a great idea! It's a little like a screen protector on a cell phone screen. Thanks for the tip.
