Cozy MK IV Serial #1537 N724CZ

This is my supplemental builders blog for a Cozy Mark IV which is a 4-seat, single engine, homebuilt light aircraft designed by Nat Puffer, with parts and plans supplied by Aircraft Spruce & Specialty Co. The aircraft is built from plans using basic raw materials. It is not a kit aircraft, though many small parts are available prefabricated. The Cozy is similar in design and construction to the 2-seat Rutan Long-EZ, from which it is derived, with approval from Burt Rutan.

Chapter 25 - Finishing - tools/results

I'd spread some left over MGS epoxy/micro onto the gear leg fairings and it had set for about three months so was cured and hard and messy. MGS micro is notoriously hard to sand. Fortunately I found some new Flexisander tools that appear to be superior to the flat boards and the 3M sanding board. I used the electric sander and cleaned up this mess in about 30 seconds. The tools are expensive, but I'm not dreading the finishing process like I had been previously. LuAnn used to help her dad in his autobody shop and encouraged me to get these tools when she saw videos of them being used. These have vacuum ports and there was very little residue from sanding.

Flexisander D Starter package includes two sanding boards, a fairing knife and an electric sander. The sanding boards use 4.5" paper and the electric uses 70 mm paper.
