Interior Observatory North

Hello good morning, I want to ask you how you put the platform to put the edge HD on the cement pedestal I am making one but I do not know how to do it, I also have an equatorial wedge and a cpc edge hd 9.25 I would like to know what screws I should get and what base for the wedge, if you have photos of that process that you can share with me, it would be a great deal.
