You are right the steering system has separate circuit after flow divider:


If I ever decide to use the main pump I will use hydraulic solenoid valve for isolation that will open only when energized. Also I guess I will open/close slideouts only when bus is parked.

I do understand the last thing you want to have is a lost steering assistant when you drive this 40 feet monster....

I am still thinking what way to go. I might go mechanical way: chains or cables or rack and pinion...

Use a single electrohydraulic pack and ram, and then a heavy duty chain to balance the pull to the left and right side. Use some large threaded rod and nut adjusters to ensure the pull is even on both sides?

Idunno - I've never built a big huge camper slide, just a few hook loaders and rollback chain flatbeds.

I'm guessing you'd want a double acting ram and valving setup, so something like these bits:

Hydraulics get expensive quickly.

Linear actuators are pretty cheap in comparison.

You might check with "Ol' Trunt"/Jack and the thread about his '35 Chevy. He built a slideout for it that is now operational appears to be quite functional.

I'd go with something like the second link provided by Aaronsb. 48" linear actuator, no hydraulic fluid to futz with. Seems simple, lightweight, relatively inexpensive and easy.

I can hear my dad's voice saying "safety first" when you talk about splicing into the power steering.

Regardless of what you use, I'm sure it will turn out fine. You do good work. Just my $0.02.

I would not tap into the power steering if it was my bus.

A little electric powered hydraulic pump like that used on pickup and trailer dump boxes would take care of your hydraulic needs if you decided you wanted to go with a fluid hydraulic system.

If you have air brakes why not tap into the the auxiliary air tank to power air hydraulic cylinders? If one leaks you won't have a mess to clean up.

Finally I finished living room slide out box.... Here are some pictures:

Just one window temporary put in. There will be 4 in the front wall and one on each side.... (my wife likes light....)


From inside:


The roof from inside:


Tomorrow I will start working on sliding mechanism.

Outstanding work!

That looks a lot more stout than any S&S slide out I have seen.

With as much strength built in you will have very little issue with racking while going in and out.

Thank everyone for good words. This is one of the reasons people share their projects. Sometimes you get stuck and the bigger the project the harder to find motivation to keep going. At the end everybody wins......;););)

Slide out mechanism.... fun begins...

One of the reasons I stooped building slide out mechanism was simply I got lost I couldn't decide what way to go.

Here are some options:

1. buy prebuilt kit.... saves time but.... to much money 6k+ shipping

2. use hydraulic cylinders.

3. use cables

4. use chains

5. some combination of #2-#4

6. hamster wheel... (somebody's idea....)


Today I spent some time thinking/searching and decided to go the easiest way (at least I see it this way)

I will use 1 hydraulic cylinder per slide out.... right in the middle. The frame I am building is really massive 2.5"x2.5"x 1/4" square tubing all welded. Also this frame will be attached to pretty solid slide out box.

Here are few pictures from today.

I cut 3" opening to have a steel square welded at tubes intersection to make it stronger:


This is an inside tube with bearings installed:


Another picture:


The same tube from side. The bearing stick out just 1/16" above tube surface:


Here are both inside and outside tubes. The green square is where reinforcement will be added:


Tomorrow I want to finish the other side and weld it all together...

Here is my progress. I welded slideout frame (living room side), some details:
2 reinforcements added one on each side:



In slide in position:




From top: (sorry about mess)




Both sides:




Before I started welding I had to make sure I had all clearances. It is not easy to set tube inside another tube. I tried metal shims but as soon as I started inserting one tube inside another shims fell out. I tried making shims from few plies of duct tape. Here is what I ended up:






Duct tape trick worked surprisingly well. I had to play with number of plies,but that was easy.

After welding all bits and pieces I tried moving slideout frame in and out. It slides very easy and straight. I even tried to push it on angle but it moves very square.

Floor joists.

I have to have a floor before I install slideout box inside the bus.
Just like always I was thinking couple of hours and floor is done. The steel bus floor is not straight. Some areas are higher, some lower. It is not critical when you have seats but in my case (slideouts) I have to make it perfect. I had 2 options:

1. use a bunch of shims
2. screw 2x2 down and straighten them after by cutting to right hight.

I decided to go with #2.

I build a "poor man CNC router table":







Finally straight "joists":



And finally plywood floors are in:

Front:


Rear:


Fuel tank access:



Now I am waiting for my friends to come and help me to lift slideout. In the main time I will keep working on insulation... lots of fun... ;)

Outstanding engineering and workmanship. Hope you get enough helpers that nobody busts a gut and we can see it soon.

Amazing job. I'm so glad you took the leap forward with the roof raise and slides. Too many people on here are fearful of what they do not understand.

I just can't express how big my smile was when I saw the pics of the slides. My smile got even bigger when I saw the pics of the slide mechanism your building. I'm so glad the link I posted of Rocky's slide system turned out to be useful. When I was in the planning stages of my build, that system was the best I found on the net.

Now that I have internet here at the coffee shop, I will be eagerly watching for updates.

Finally the box is in!!!!

Yesterday me and my friend finally put the slideout box inside!!! The box was under 200 lb, not too heavy for 2 russian bears but very awkward. The centre of gravity is much closer to outside wall because there is no inside wall.
This is the first time I can see whole bus from its side with aluminium side panels:







The box is in out position. Pulled it by hand to take some pictures:







Inside the bus. There is no floor yet and second slideout but already it looks spacious:





With slideout inside:





Now I need inside side rollers and some bits and pieces here and there.

Fantastic job друг, it's really coming together.

You and I have a very similar bus and the esthetics of the entrance door bugs me a little bit. Look at the left side and you'll note the slope down from the front of the nose towards the wheel well. on the right side, it's squared off (and lower) to accommodate the entrance door. I'm planning on shaving the body to be the same angle on both sides, with a slightly smaller (by a few inches) door.

The approach angle on the vehicle will be slightly better too.

What are your thoughts on door mods like that?
