They were narrow at the bottom and wider towards the lip of the nose cone.
The nose cone was way too tight. It took some sanding to take the ribs down for a good fit.
The tip of the nose cone had some flash and a dimple at the top.
Mentioned earlier, the fin die-cut was poor.
Die cut fins need to be gang sanded. The picture shows how much they are off before truing up.
The body tube seam was so thin that the primer filler could have filled it.
I still applied CWF to fill them.
After sanding there was a few gaps. The inset shows the second fill before sanding.
I have noticed that some of the BT-20 Estes nose cones have a bad taper to them, too small at the bottom, too large at the top. It's almost as if they were molded to be a cork rather than a nose cone.
ReplyDeleteHi Lonnie,
DeleteOccasionally I find ridiculously tight nose cones. I'd rather have them too tight and sand them down to size than use a tape wrap.
