i think that 4 foot across the center would work fine.......but would be a little more tricky towards the sides as the roof curve begins to get more radical. I know plexi-glass can easily be bent into extreme shapes by applying heat. A 110,000 btu salamander heater and a pair of welding gloves work great.......i'm not sure how the mirror surface would react to that treatment however.

You might be able to bend the mirror enough just using screws (not heat). I'm not sure.

I need to paint my bus, maybe I could come by and help you with you new bus in exchange for some help painting mine. The school bus "yellow" has to go, but one solid color never seems to look good on a bus. You can see my bus on the skoolie gallery on the last page.

I was thinking of painting it like the General lee from the dukes of hazard. Kinda thought that would be funny, paint one of the slowest vehicles on the road like a fast car famous for doing crazy jumps.

where are you from?

I"m all about helping people....especially the crazy skoolie type

I'd be more than happy to give you instructions in how to do the prep work, and all the masking. I hate masking! uggggggg. If you get her all prepped, I'll paint the bus for ya. Obviously you need to purchase all the supplies

I live near detroit michigan.

I live in Grand Rapids, MI

I have no problem prepping my bus, but then it becomes undriveable, so I think I'd have to do it at my house. I just need some help and/or pointers on how to paint it. I also have no problem buying all the needed stuff to do it. I have an air compressor and I can borrow a spray gun. So I'm half way there right?

I've had my bus for over a year, and I worked on it last summer a lot but this past winter/spring I havent done much at all. Since I found this sight last week I'm motivated to work on it again. I couldnt get to sleep lastnight becasue I was thinking about everything I want to do to it now. In fact I just got back from menards and spent about $70 on stuff for it. Why couldnt I have found this sight last year? I also think it helps to have a camping trip planed to get you motivated to work on it.

Anyway back to your bus: how is your new bus comming along? do you have any pic's of your latest progress?

So far, the bus project has been moving ahead at lightning speed which seems good.......but it's actually rather dull and boring. Until now, this bus is nearly identical to the old bus with the exception to hole for the jacuzzi in the roof rather the wall.

Today i was at the junk yard looking at hydraulic cylinders to open the new roof flap, but the only cylinders i could find were off of a garbage truck and they were just way to huge in stroke and bore. Probably 4" bore and at least 48" stroke. The junk yard guy misunderstood what i was trying to do. He looked at me like i was crazy and said "you want to raise the entire hot tub up through the roof?" I said no, i'm just looking to open the ceiling above the......Wow! What an incredible idea, having the entire jacuzzi raise up through the roof? BRILLIANT!!! Why didnt' i think of that?

He said if i pull the cylinders myself i can have them for $25 each. I only need two plus a good amount of steel to make it work, but it's cheaper to just go ahead and buy all four cylinders and put one at each corner of the jacuzzi. The boittom of the cylinders will extend through the floor about 24" and attach to the frame. The other end will attach to a special platform that the jacuzzi rests on. Doesn't sound complicated at all, does it?

Still have to figure out the hydraulic pump/valves. I might steal those from the donor truck while i'm at the scrap yard. I don't want to use air for this application because air is much more unpredictable.

I would go ahead and study a good quality vehicle hoist to accomplish the task of lifting a heavy object that height. I think it could be done very well and safely too. our 12000 auto hoist only uses one cylinder under one of the ramps to lift a vehicle or truck the height you'd need. You need to be sure that it will lift evenly and lower evenly to prevent heavy side loading. The vehicle hoists use mechanical catches ( air released ) to hold the vehicle in place after its lifted for safety. It can be done ! If you have the hydraulics anyways you could also build a hydraulic leg setup too, for stability.

Sounds like a plan! ...and your blueprints look like they are done by the same draftsman that I use...

On second thought..... I have a 12 volt electric pump that does power up, gravity down, but it would be really really slow since the cylinders have such a large bore.
The high pressure hydraulic hoses are really expensive too

I think i'm going to use air over hydraulic with about 100 to 150 psi. That doesn't sound like a lot of pressure, but a 4" bore will have 12.56 pounds of force for every pound of pressure on the input side. In other words 100 psi going in will yield about 1,250 pounds of lifting force on the working end for each cylinder.



A 4" bore with a 48" stroke would require two gallons of fluid for full extention. I'll use small diameter tubing and fittings so that in the event of a broken hose, it would take several seconds for all the fluid to be forced from the cylinders adding a measure of safety. I'd like to make the jacuzzi rise to full extention in 7 to 10 seconds.

A safety lockout mechanism is also important. I'll go take a look at the ones used on automitive hoists.

I also need a good source of air.....since this bus has hydraulic brakes.

holy crap this is getting compliated, but it would be awsome when finished. Are you going to build a deck on the roof and have the hot tub rise up through a hole in the deck? That would be awsome.

Two words: DRY ICE!

With your lighting skills, and the jacuzzi rising through the roof, you need some spooky dry ice fog boiling out of the place...and the theme from 2001 A Space Odessy (Thus Spake Zarathrustra is the title of the piece, I think)
