Alt/azth clamps for dobs?

Hi all,

A recent star party at a school brought the notion of some type of clamping system for the altitude & azimuth axis. Well balanced dobs are a pleasure to use, however they are very easily pushed out of direction by less experienced people, .

Does anyone know of some clamping system, DIY prefered, to offer some resistance to accidental push & pull?

This may be the last design element needed before I start on remodelling my big dob. What ever clamp systems are mentioned can be easily incorporated into the final design. This is in no way to 'take up slack' in an unbalanced system, though may come in handy if some over sized EP were to be used, .

Thanks in advance,

Mental.
