Raising the Roof w/ jack Post

[Intalleyvision]

So I'm curious if you secure either end to the ceiling/floor if 2/4 of these would work in raising the roof?

They're probably very safe in terms of not having the roof come crashing straight down on you. But the flanges won't provide a great deal of resistance to sideways forces like wind, so it would be wise to supplement with something on an angle in two directions to prevent a sideways shift and collapse.

Have a look in your local classifieds... I bet the same $170 will get you a good set of used scaffolding and part of a set of screw jacks for it. Though if you have some other project in mind to use the jack post after this one is done, I can see why you'd go with the jack posts instead.

I agree with family wagon.

Scaffold would be a far better choice, and is great for the rest of the bus conversion.

I have one of those jack posts in a corner in my basement. It's not identical but it looks really close. The previous homeowner left it there after a renovation. FYI, the top plate on mine has a lot of play in it.

No I'll do the scaffolding method. After all the research and talking with Nat (who's been super helpful) I think it's the safest and best bet.

I"m looking for some scaffolding myself and finding the good stuff to be expensive.
I may just end up building something out of scrap tubing and or angle. Same principal though.

Check out wmkbailey's build and how he did his roof raise.

2nd, I followed his example & very well documented, I even used his sheetmetal lift when I did my skinning

I really enjoyed his build.

I like the system he used and copied.

However, it still lacks a safety, in case one of the nuts or the threads on the rod fail.

Scaffold does provide that safety. Even if the roof got blown sideways, the roof can't crush you.

The safety factor, and availability is why I used scaffold. You can get it anywhere for cheap, or rent.

If renting, a few days max is all you would need the scaffold.

Wasn't sure what they were looking for for their roof raise Nat, but yes- Safety is paramount.

Does anyone know of a good video showing the scaffolding method in detail? Link? Thanks!!!!

[family wagon]

I don't know of any video showing that method, but nat_ster posted pictures of it there. I can see in a couple of the pictures that he's got a 2x4 runner spanning 3 or 4 of the roof ribs with the scaffold frame placed roughly in the middle of the board, and an extra pair of 2x4 braced on an angle to prevent the whole affair from toppling to the front or rear.

When I used this method I used a set of screw-style leveling feet under the scaffold. They didn't turn real easy; some grease or even a thrust bearing would help.
