For years I have used a Dremel tool both AC and battery powered with a small rotary file or diamond grit bit for fine detailed cutting it is very fast and easily controlled. I finish the edges with the drum sander. Speed, it's not that critical.

I have had mt PW 300 for three months and just started it yesterday. I am cleaning up the wing tubes with a brake cylinder hone and it is working well, not fast but I will not have egg shaped tubes. BME 50 is mounted and all hinging is with Robart hinges glued with Gorilla Glue. I am replacing the tail wheel with a CB leaf spring type. Futaba 9CAP for guidance. I have many pages of notes from this site and these have been a great help in making some decisions. While the plane may not be perfect I thing it is a good value. I have never built a plane in over 30 years of modeling that I did not modify or re-engineer.

Thanks to all for your input
