Yep. The dividing line start's right here Gent's! I'm not offering to make it....NO access to a lathe these days, so dont ask. Dont get me wrong...I would LOVE to knock up half a dozen of these baby's & flog em' off because I'm currently unemployed. I'm just offering....for the guy's that have the inclination, the time & the required tool's to build this mount. If I was in a position to make them, I wouldn't have dared put the plan's up on here for all to see now would I !?? And it's not like Iv'e got a patent on it or anything, lol..I'm here to help you guy's out...FREE...GRATIS.
Don't winge about not having an EQ mount big enough to swing your 8" right up to a 12.5" reflector, & therefore your committed to buying a dob..

Because you have option's! If you dont wanna make it yourself (or can't) down-load the plans and take em' to an engineer & see what he reckon's.
Have a good evening, Gentlemen!
