Jaegers 6" f/10 "GJD" OTA Construction - The Dew Shield (cut to proper length 12.5" inches)
 

Dew Shield being cut to proper size - 7. (Click to see an enlarged image.)

 
The Dew Shield has now been cut to proper size with my hacksaw. It is the section of aluminum tubing to the right and is 8" OD x 12.5" L x .083" WT in dimension. I know I had to put in a lot of work and time to get my tube cut accurately, but if you do not have better tools, this method works perfectly and is well worth the effort. All you need is the desire to do a good job and a great deal of patience.
