Hi Yugant
I had the same things, just too much load to bring in/out. I contacted Altair on the same thing, they never replied. In practice sending something weighing ~80~10kg from UK is not ideal cost wise.
I had a local workshop make mine. I did up some drawings with CAD (I can send them to you, solid edge 2D drafting, although I can save as other formats) and had them cost & build, allowing them lots of latitude on parts (although I asked for a max dia pipe) and materials.
End product is great, although over budget by 30%...total cost $980 delivered. But it's a beast, ~ 200kg, way over designed but as solid as they come. Absolutely no ringing. I suspect you can change my design downsize materials and still be well within the deflection specs allowable (
> .5 arc sec deflection (caculated), lateral force ~22 newtons).
Bert spoke some good info on piers recently,
see here.
Just need to now put in the concrete bas and build a shed around it.
