Yes, finally heading down the pier path... (also taking inspiration from Meru's pier build
http://www.iceinspace.com.au/forum/s...d.php?t=114718)
I have a pier with the following dimensions
250mm round top plate, 250mm square bottom plate (both with pre-drilled holes)
100x100mm square, 900mm high and 6mm thick steel.
I plan to mount my EQ6 head on it.
I have the following questions for experience pier builders out there:
1. Do I need to weld a heavier bottom plate to my existing bottom plate? I was thinking of a 350mm square plate of 10mm thick.
2. Gusseting: I plan to put two gussets on each side. The pier will then be secured with four bolts between the two gussets and then four more at the outer corners of the new base plate (see my sketch). The bolts will be poured into the concrete base (450x450x600 (d) with reo)
3. Top plate. I am thinking of a new 250mm round top plate 6mm thick (same dimension as my existing) and attach the two via 4 thick threaded rods (is that a "rat cage"?) and then make an EQ6 adapter.
Any comments on my proposal is very much appreciated.
