Damb, that's a sounding rocket if I've ever seen one. What's it do on a N1000?

N-1000 wont fit. Only a 44" booster.

Fins are now beveled and one is tacking in place currently. 3 more to go this afternoon, then onto internals.

RE: fin bevel... what tool(s) did you use to do the job?

Once the nose cone avionics tube gets in, we will be darn close to done. The 54 tube and coupler will house a Kate transmitter.

Ran out of daylight, 2K clear will have to wait for another day...

Seriously! Rattle can paint for something that size! I'm very impressed!! How many cans of dupliColor does the first coat take?

 

[ThePlmbr]

Now it looks even better!

2 cans of primer, 2 cans of blue, half a can of red, and a full can of white. It'll take 2 cans of 2K clear as well.

@Theory, conical nose cones seems to be rather photogenic.

That's the vent hole for the nose cone and upper airframe. When you drill the hole on the seam, your shear pin holes line up exactly where they should each and every time.

Absolutely love how well that Aeropack fits on there!

Great job

Using HPR Tools @PosTart fin guides and tube marking guides.

I 3D design and print my own tube drill and marking guides when needed.

I'm curious as to how you slotted the tube.

It was not elegant... Drilled a hole at the top on the intended slot location and one at the bottom. Enlarged those holes slightly larger/wider than the 3/16" fin stock. Using aluminum angle iron, scribed two lines connecting the outer edges of the holes, then used a dremel moto-tool with flex shaft and heavy duty cut off wheels to cut out the rest of the material. Then heavy scuff inside and outside of the tube. Sorry I didn't get pics of this step as its rather messy and didn't have enough hands.
