Step 9: Glue on and Finish the Fins.

If I had to redo this project, I would choose a different method than what I'm about to describe:

Taking my fitted fins, I carefully, one-at-a-time, glued each fin onto the rocket body, using CA glue. Aligning and straightening the fins proved difficult and unwieldy, and I was never quite sure when the glue would decide to cure. Also, until I got three of the fins attached, it had difficulty balancing. After I attached the fins, I coated them with a thin layer of super glue to get them to match the aesthetic of the redheart cap.

Instead, I would recommend cutting a slot in the bottom of the rocket body, and placing tabbed fin cutouts into the slots at the bottom of the rocket. It makes alignment, shaping, and glue-up way easier. If you do this method, I would recommend finishing the fins before you attach them, using a quick polyurethane coat to avoid cloudiness that can be associated with super glue finishes that aren't applied in a thin coat.

<p>Nice build! According to my experience, you may get a clear aspect to the acrylic without using super glue, just by sanding to a higher grit.</p><p>I do this for acrylic pen blanks. I use micromesh sanding pads, going up to 12.000 (slightly wet the pads to avoid super fine dust).</p><p>I guarantee your acrylic window would look clear again with grits above 1.000 :)</p>
<p>That's a great tip! Our shop very rarely has sandpaper over 400 grit since we're an academic makerspace and students rarely have the patience for that much sanding, so I don't have a lot of experience with crazy fine grits. Maybe we should invest in some. Thanks!</p>
<p>now give it a flip top &amp; put a shot glass inside; you're welcome. &quot;Rocket shot&quot;<br><br>ADD or give it a flip top &amp; put a 50ml bottle inside</p>
<p>Very Cool, Thanks for sharing.</p>
<p>As the recipient of the original, I can confirm that it's a pretty awesome gift! At some point I think I'll make a little light-up stand for it or something.</p>
<p>How about an LED that shines up through the bottom of the acrylic rod and illumiates the windows?</p>
The acrylic is inserted from the side so I'd need to drill up through the bottom in order to do that. Although I'm sure I could make it work I'd rather not modify the rocket itself.
<p>This turned out really well! It's adorable :)</p>
<p>I love lathe puns!</p>
Really nice! Voted
<p>Thank you so much!</p>
<p>That is wonderful, definitely going to have to try this project out. Thanks for sharing!</p>
<p>Thanks! It was a pretty quick project - like 2 days of work - especially if you do the fins more efficiently than I did, haha.</p>
<p>Absolutely beautiful!</p>
