The BT-4 body tube had no seams! At least none I could feel.
The launch lug is long and I could feel the seams with a thumbnail.
First up, rough the surface so the CWF will stick to it. 400 grit was used to take off some of the gloss.
The tapers in the nose cone will be interesting to sand.
After brushing on some CWF, pencil lines were drawn around the high and low spots. These will help as a sanding reference.
This tungsten carbide sanding block surface stops right down the side.
You can sand up to the edge without sanding down the adjoining angled surface.
Check the sanding dust on the block. It will show you if you are sanding the sides square.
Clever technique for sanding a multi-tapered cone...

Hi Bill -
ReplyDeleteFilling the grain on all the nose cone tapers was one of the more difficult steps in the build. I didn't want to sand into any adjoining surface.
