To use this mount for my 10" Newtonian, I need additional counterweight, cca 15kg in total..

So I decided to make my own.

The start was the round plastic 4 litres cake box ($2.50 at local shop) to be used as a mould and 1/2 bag of premix concrete, leftover from pier slab ($3.00?).

A friend machined for me the plastic tube with 18mm internal diameter (for counterweight rod), which I center-placed into the plastic mould (cake box).
I also added some reinforcement for the second half (actually, additional 5-7kg, as right now I already have 10kg).
Then the concrete was poured in.. now I am waiting for it to set and then to proceed with the rest (it was cold last night so the setting process is slow...).
