127mm f/9.4 OTA Construction - OTA Main Tube Cleaning (removing residue)

 

To remove the aluminum dust and residue, Goo-Gone was used to wipe off its surface... (Click for enlarged view)

 

With the main tube sanded and buffed to a satin finish, it was time to thoroughly remove the residual aluminum dust and debris from its outside and inside surfaces. This step is critical in that you want the surface to be as clean as possible to aid the primer and paint to adhere as good as it can. To clean the tube, I used a product called GOO GONE XtremeŽ remover. It is an acetone based product that removes all signs of particulate matter, as well as grease and grime, leaving your tube in the cleanest condition possible for painting. You can also use straight acetone like many do, or even mineral spirits. In either case, PLEASE DO NOT SMOKE, CAUSE A SPARK, WORK WITH THIS AND ANY OTHER SIMILAR PRODUCT AROUND HOT AREAS WITHOUT PROPER VENTILATION - READ, FOLLOW, AND UNDERSTAND ALL WARNINGS AND INSTRUCTIONS ON THE CONTAINERS. But before we begin painting of the main tube, we have to make the baffles.
