These Piers have an 8mm thick laser cut base 500mm wide, 4mm thick laser cut gussets, 5mm thick tube with a laser cut 10mm thick top.
The bases have 4 x17mm diameter fixing holes and 4 x 12mm threaded pier levelling holes.
The bottom plate has a 130mm hole underneath and an additional cable outlet hole at the bottom of the tube opposite the "birds nest"
The top is drilledand threaded (no nuts required) to the Meade 6 x 8mm pattern (fit Pulsar adapter plates)
This also has a generous centre hole and 4 x 10mm holes (for JTW adapter plates)
If that is not enoughit also has 2 x 10mm threaded holes for the azimuth
stop for SkywatcherEQ 5 and EQ 6 mounts (and compatible).
(should also fit ASToptics pier adaptors)
In fact because of the wide base and flexible design,
you could even purchase your own 12mm threaded,
locking castor wheels (x 4) and make a fully mobile pier!
The choice is yours.
If your base is not perfectly level, or flat, you can use the 12mm threaded holes at the base of each gusset
to "trim" the pier level. Simply choose your orientation, mark the fixing bolt positions(a chalk outline helps too)
Insert 4 x 12mm bolts and adjust till level. Tip over pier, drill holes for fixings (and fit?depending on what is used)
use a gap filler under base to take up any gap(if required), slow set resin or sand/cement mix, coat the protruding threads
with grease and/or plastic film (cling film ideal). Tip back pier and bolt down just enough to seat pier onto the levelling bolts.
When filler has fully set, levelling bolts can be removed (to prevent tripping) and pier fixings tightened.
The supplied cone washer (if requested) fits under the large centre hole so that the cone fitsinto this and reduces the hole to better fit the mount fixing bolt.
This helps to better centralize the mount when an adapter or puck is not used.
