Quote:....I have a question about the cross support for the support posts.Why did they make it an X instead of 2 2"x8" boards going horizontally from the upper portion of the pole on the left of image to the other and then install a couple of 4x4 angled supports from the pole to the cross bracing?...

I love everything else on your build except for this. Your eye goes right to that X brace and is slightly distracting.
Quote:The X bracing is even stronger when the crossing pieces at the middle of the X are joined. It may not be pretty, but it is functionally excellent.

Quote:Yup - that looks exactly like the previous model of the Pier-Tech PT2. By looking at all of the models of the Linak lifting columns, the current Pier-Tech PT2 looks exactly like the Linak LP2.
You said you "found a cache of brand new Linak DL2s", which implies more than one. Where did you find them for sale?

Quote:...what prompted the split roof design? What advantage did you feel that offers over a single roof that would roll off to one direction? Was it the weight of a single roof? Some other factor?
Quote:Did keeping the weather out where the two halves join right over your precious equipment cause any concern?
