Next up, external fin fillets and
glasswork. Finally you get to see me,
whoopee!
|
Yes, I admit it. I measure and mask my fin fillets. |
Then I use the catsup squeeze bottles to
apply epoxy that is made into paste consistency with a milled glass additive. |
Then I use the cutest little paint
roller to wet out the glass. |
After the wet out I trim & wait (…just like everybody else.) |

A G10 bulkhead came with the kit. I cut it down to fit here (picture on right)
in the forward end of the nosecone, instead of the aft end of the nosecone
shoulder. |
Nearly impossible to photograph, is the
hole in the center of the bulkhead.
Actually the bulkhead is tough to photograph too.
|
I’ll be using about 6 pounds of lead birdshot to move the center
of gravity forward enough for good stability. I’ll poor the shot into the space forward of the bulkhead,
through the invisible hole. The plug
is removable to adjust or remove the weight.
Once the weight was right, I filled the remaining space with plastic
beads to keep the lead shot at the forward end and stop it from moving
around. Besides
wanting to be able to remove the weight later, I consider 6 pounds of loose
birdshot to be slightly safer than a 6-pound solid lump. In the event that the bulkhead fails, a
shower small shot is nearly harmless, the lump is not. |

|
This was a handy way to hold the nose cone while I worked inside
it on the bulkhead. |
If you’ve never worked with this stuff, think about it! (I keep 2”, 3” & 4” on hand.) |
The painting begins (after a vigorous
final raw surface wet sanding.) |
