FlisKits Space Raider Build, Part 2, Making A Nose Block

I didn't have a BT-20 sized nose block handy so I hit the spare parts drawer.

I found a 20/50 balsa adapter. I tend to hang on to spare parts. You never know when they might come in handy.

The narrow upper end was used as a diameter guide.

The lower wide end was shaved down stopping before getting to the BT-20 diameter.

The rough sides were sanded down and evened up using 220 grit on a block.

The final fitting was done by sliding the block into the tube. If the block stopped, I knew there was more sanding to fit. 

Here's the final nose block, much longer than needed.

I'll cut it down to size when I figure out how long it needs to be later on in the build.
