Just a thought but wouldn't it be better to take the scope to Chuck so he can fit the dew cap to the tube and y'all would not have to worry about something being mismeasured? Just sayin... patrick On 10 Nov 2011, at 17:30, Joe Bauman wrote:

Thanks, Mat, But Chuck has kindly offered to make one for me, if I just pay for the material -- he knows how -- and I'm overjoyed to accept his offer.
My pleasure Joe. Hey, in addition to your tube OD, can you send me a photo of the front of the scope? I need to know how far back the dewcap can be seated before it runs into an obstacle such as guidescope rings and such.
The drawer liner material is a good suggestion. I'm thinking of a thin polycarbonate core to prevent sagging if the foam itself is too thin.
