Pier Time .

Recommended Posts

I’m constructing a pier for a Mesu200 Mount ..   but wondered how many bolts should I use for the top levelling plate ..  3 or 4 , and what size studding should I use .. ? 
 

Your thoughts would be much appreciated.. 
 

cheers Brian

Personal choice would be 4 bolts/ rods and M12.   On my last pier which was for an EQ6 I used M14 rods but everything became more expensive because at this size it is outside of “normal” high street stockist size ranges.  

M12 should be plenty strong enough...but then I have no experience with a Mesu200.

Not done a pier myself (yet) but previous work history (scaffolder many years ago) suggests that 4 fixed legs are more stable than 3 and share the load better.

Imagine a round coffee table. Which one is least likely to tip over under a heavy load of coffee cups, therefore ruining your carpet?

Thanks for the replies ..just for clarity  ..it’s not the bolts to hold the pier down .. there will be 4 of those 👍 , these are for the levelling plate on the top of the mount..

Hi Brian

The pier adapter plate for the old Mesu uses 6 bolts.  https://www.modernastronomy.com/shop/accessories/mesu-mount-accessories/mesu-pier-adapter-plate/

I am sure M12 x 6 would be plenty.

If in doubt use more.

The cost of studs/bolts/nuts compared to the mount and the pier materials is negligible.
