Very glad I popped in here and read about turning a 114mm into a Dob! What a great idea! My 114mm sits doing nothing as our 6" gets far more use and has a much better mount. The 114 was our first 'scope, and making a Dob base would mean it would be easy to put in the car when we go camping and stuff!
And grantspants - keep on gazing - your efforts will be rewarded!
