Is that line of drill holes curved on purpose or is that an accident or an illusion?

Looks like he drew a box around the area he needs to clean out, then used the drill to remove a large portion of the material. My guess is a rasp and/or sandpaper is being used to do the final touches.

So, the fact that they're not straight doesn't matter.

I think you are right - the slot he posted later looks normal. At first I thought it was an illusion or that he was intentionally curving the slot to add some spin to help with stability.

I see ya'all got that worked out among'st yourselves. :grin:

Material removal for the fin slots completed.

And of course some thru the boattail fins are needed to fill the slotted boattail.

More body work is still needed.

That is a thing of beauty....

I'm glad you like it! :grin:

Yup, yet another impeccable build. Can't wait until she's painted.

The leading edges of the fins were rounded off and the body work is done. Construction of the logo rocket is completed.

Looking very sharp! Great job. Those thick fins really make it look scale appropriate.

You sir, have a keen eye for detail. Glad to have your commendation.

Don't have a paint booth, and the paint booth I don't have dosen't have a carousel.

I wrap masking tape around the end of a PVC pipe until it fits snugly in the motor tube, then rotate the the piece being primerd with one hand and spray paint with the other. This is done outside with all the neighborhood bugs in attendance.

After painting, the piece has to be left untouched while drying. The PVC pipe is placed into a plastic milk jug with several pounds of gravel on the bottom of the jug, preventing everything from tipping over.

Same thing is done for the nose cone 'cept a BT-60 with a wrap of newspaper is used instead of PVC pipe.

Also, a wide mouth 1 gallon glass jar is use inplace of a milk jug.

The grainy texture of the grey primer was wet sanded until smooth.

That is fantastic. Very clean build and perfect scale from my view.

How much do you think it will weigh?

Wow, very smooth! I'm going to have to try wet sanding one of these days.

Wet Sand? I just need to sand period. Then maybe wet sand. What is the key to wetsanding?

The key? I'd say it's key to stop sanding before you sand thru the coat of paint your smoothing out. :grin:

LOL. That is funny, but guilty at times.

Thanks. All the seprate pieces weigh'd in at 6.3 oz.

I'd guess the final weight to be half to three quarters of a pound or so. But I'm concernd about looks, not weight.

I agree; painting is hard, but stuffing a bigger motor in it is easy!
Good job on the build, it looks great! To be honest, I would not be surprised to see you win the contest.

I forget... how is the contenst to be judged? A poll of eligible entries? Or the Admin/mods?

There's a thread with a post explaining it in 'The Watering Hole'.

In the past I've had trouble getting a clean change of color paint line around the top of the fin and were the body tube meet.

So I gave this idea a try...

First, to get the masking to do what I wanted it to do, the top of the fin was drawn to scale.

Then the drawing was coverd with clear tape.

A piece of the masking material was placed over the drawing and cut with an x-acto.

The mask can be peeled of the clear tape and transfered to the rocket.

These are the tools used to place, adjust and rub the edges of the mask down.

Pretty clever. I've used a hole punch to put a half hole in the edge of masking tape, but it's not as exact as your method.
