So I want to build a pier. I wasn't going to rush into this but I have the chance to borrow a dingo digger for free, so I can't pass that up. I wasn't looking forward to digging a mega hole by hand
So on Saturday I'll be digging a 800mm deep by 600mm square hole for the pier. I plan to make a steel pier so I can unbolt it and take it with me as I think we'll be moving house in a year or two.
At the moment I have a HEQ5 mount and GSO 8" RC, so I'm imaging at 1800mm focal length.
Well today I went to a builders demolition yard and found these two beasts.
Post A is 150mm square and has a nice top plate already.
Post B has a great base with gussets and all but is only 120mm square.
Both are 6mm wall thickness.
So which one should I get? Either one is under $150 so the price is right.
I'm leaning towards Post A. Its a bit cleaner so won't require as much prep to paint. And the extra width is great and should mean I won't need to upgrade for ages or ever. the nice plate up the top can be the top plate or I could flip it and use it as the base plate. Also with my current gear I don't think I need to worry about gussets. Or I could cut a section out of the middle and weld it back together to use both top and bottom plates.
At the moment both are WAY too tall, I plan to have my pier about 1.5m high to the top plate so I'll be cutting which ever one I get down.
So basically I'm hoping I can finish off one of these posts for a total cost of $250 or so (add top plates and bolts etc). Welding isn't a problem.
So do you think, am I on the right track?
