when I realized that the first pistons had been stucked in the wrong position, I decided to remove them. So I used high pressure air but I didn't use any wood betweem them (my third mistake 
). They poped violently and hited one on the other breaking the edge a litle more....
... and after, I stucked them again this time in the right position:
and a litle more done:
and once more, not having a piece of wood between them, resulted in this....
Nothing too serious....

in July 2008 I decided to get a new machine to clean the underside of the bus. But before geting that machine I first bought a 100L air compressor. It wasn't a big air compressor but it was enough for what I had to do.
The person who sold me the compressor told me that I could carry on its side .... bad advice :evil: !
During the journey of 300 km's between Lisbon and Viseu, much of the lubrication came out and spread throughout my car.
.. but after reading the instructions I found wich kind of lubrification was needed and so, I filled it up again:
.... and once at work, it has come fairly quickly to its limit:
... and a small sand blaster that a friend lent me:
After some minor air leaks solved, I was ready to try it... but it was too late so I waited for the next day.
.... but I was afraid that the sand used could scratch my paint job so I decided to cover the bus completely:

next day, early in the morning, I brought outside all I needed to start cleaning the bus:
but first some protection:
and...
Sand ricochets and bounces everywhere.... and the glasses I was using weren't the best choice
I used some cardboards to try and reuse some sand
but even with this very small sandblaster, I realized it could work...

finally this suport was ready to be used.... but I would only use it inside the garage:
Before I started using the new sandblaster I decided to laydown a large piece of canvas so I can reuse the sand a few times before it turns only dust:
and after I pushed the bus over it:
... I then put the new compressor outside and conected it to the sandblaster.... I was ready to start cleaning it :mrgreen:
this time I decided to sift the sand before using it and every time I reused it again:
some security equipment... :mrgreen:
... and nothing happened 8) . I lost a few hours before getting all the taps in their right positions

but when the sandblaster started working properly, the plastic visor that came with the machine quickly became scratched...
... and so, I had to make a new one, this time using glass:
cuting the corners to prevent some accident...
... but this kind of job was working and the bus was being cleaned :mrgreen:

the job was made while lying underneath the bus. Not the best position because all the sand used was falling over me...
... and to prevent being cuted if the glass broke while using it, I add some more protection. Security first 8)
-"Hello! I came in peace!" :mrgreen:
... and so, every time the sand from the tank finished, I had to pull the bus from the canvas to reuse it...
untill by the 4/5 time of reusing the same sand, it was only dust:
... so time to get new sand:
The sand rebound was so violent that quickly the glass got scratched, so I had to cut a lot more:

I love your persistance Joaonar, and you have a lot of good ideas too - bit of an engineer maybe?
Nice job on the sandblasting too.
Now marine clean, metal ready & POR15 the sh** out of it :mrgreen:

Im really enjoying this thread 8) , your pictures of every detail is refreshing and brilliant.
Great job on the calipers, and i was going to buy a blaster for home use but wanted to see what others ideas were on them. No need now after seeing your results

how long did it take to do underneath?
yes, stuif! It's a very good machine and the result is excellentstuif said:
Thanks T2-Nate. Engineer? no... Graphic Designer :mrgreen:T2-Nate said:
Is there any feedback on POR15 products? I got some and I intend to use them... just hope they are as good as I think they are (and as good as they were expensive) :roll:
Thanks, johnny. I've got a lot more pictures to show and experiences to tell about this machine :mrgreen:johnny said:
Thanks again, gninnam.gninnam said:
Yes, it does....
Thanks easy!easy said:

johnny, it took me about 15 days.... maybe a few more. But there was some mishap along the way ....
I really believe that with a larger air compressor (about 200L or 300L) or 2 air compressor with 100L each but with a larger and more powerfull engine (instead of 2 HP, at least 3 ou 4HP each one), I could make it in half that time...
The sandblaster needs pressure of 8 to 6 BAR for an optimal performance.. and of course, new ceramic ferrules, because when they are too used, the performance drops a litle.
And don't forget that I had already spent some days scraping the anti-stoneship (anti-gravel) because if you try to remove it with the sand blaster, then you'll need 8 BAR, a completely new ceramic ferrule and proper sand for the job (with a lot of silica)...
and, if you use one of these machines: Body Roller the job will become much more easier because you will always see where the sand is hiting...
Doing this kind of work lying under the bus, is not the best choice, because the dust and sand will fall over your mask and will not let you see easily where you're cleaning and besides, there isn't much light either even if you use a lamp like I did (pictures to come :mrgreen: ).....
I hope I have made myself understood with my rusty English
