hi,

here is (finally) the copy of the letter from the Rennes prefecture (35) regarding the possibility for people holding a D license (TCP) to drive a VASP (modified coach): http://img63.imageshack.us/img63/9944/permisd1gy.jpg

re it seems to me that now the 'technical inspection' for HGVs (and so coaches) is done in the private sector. do you have any info on this? do you know a 'welcoming' center in the Paris region? (send me a private message) does anyone know where I can find steering ball joints for an S45/53 from 1974? hey debetwin, it's great to see you ravers :) maybe on the 1st of May... patrick26 what's this all about:

driving your bus while it's being converted is a hassle! indeed, if it's missing the seats, it no longer complies with its bus designation, and six months of modifications pass quickly, so you won't be able to get it through the technical inspection (especially not, because those jerks can put a big S -safety- mark on it that gets it taken off the road).

does that also apply between technical inspections if they're too far apart? my coach waited 2 years before being officially approved as VASP... (2002)

Me too, I have my S53, but:

No insurance company will cover it since I don't have a Category D license. Fleet insurance companies will cover vehicles as long as you have 3 years of driving experience with a license in that vehicle category.

That said, insurance companies like AXA asked me for a claims record (issued by your insurer, which lists any claims and bonuses, etc.). So I sent my Category B license from 1999, a claims record, the Category D license of the person who will transport the bus for me (thanks Benhurd), and their claims record. AXA replied "yes, but your friend has a claims record for a car, so I can't do anything about it, especially since you have nothing with us—we'd need some history with us." Sure, I'd be happy to move my Twingo to AXA, but that wouldn't give me more history with them.

My insurer, which is very good and inexpensive—MACIF—doesn't cover heavy vehicles. They have a subsidiary but won't cover a coach unless I have a transport company... anyway...

It's either/or: I either start a transport company and buy buses... or I don't insure my bus.

I could get it transported by the company I bought it from, but once it's here, on public roads or private land, what if something goes wrong...? And for transport to the DRIRE, etc.—is that X times 50 in daily temporary insurance...?

I'm looking for advice on this.

Anyway, for everyone else:

VASP Driving with Category D License

I doubt the letter from the Rennes prefecture would be valid with the cops—it doesn't cite the relevant road-code article(s).

Technical Inspection

Email quoted exactly as I received it from Autovision PL:

Following up on your email of January 24, 2006, I'm sending you the requested information:

Price of inspection for a TCP 96: €31; for a motor vehicle: €83.68. These rates are the same for professionals and private individuals. As for inspection frequency: TCP every 6 months, and for motor vehicles or trailers every year.

To reclassify your vehicle, before the technical inspection you must go to the DRIRE with a vehicle reclassification file and request a receipt defining the new characteristics. The vehicle definition is on your registration card under "Type." The vehicle will be presented in accordance with the characteristics defined by the DRIRE.

Next, request a SIREN number on a case-by-case basis to book an appointment online.

That said, if the inspections are spaced too far apart, it's no problem if you can show a document proving you have an appointment at the nearest DRIRE to your garage, but verify with them anyway (as long as you come back before the inspection validity date expires, and if you don't plan to drive the bus for 2 or 3 months, over 5 to 10 years you can gain an extra year). You also have a month to drive the coach after the validity date expires, so you can save €83.68 every 12 years. It adds up.

Emergency Exit Question

Is an emergency exit required in a bathroom? Benhurd has a windowless bathroom—he sealed the window and only the roof vent is usable. But it opens onto the salon, and in case of a bathtub fire he can escape either through the bedroom or out the front of the coach.

Layout Ideas

Partitions: I'm not entirely sure how to do it, but my basic idea was marine plywood 22 mm thick (shuttering boards for those unfamiliar), since I work in construction I can get large offcuts, even some new boards. Otherwise, another option: 10 mm boards assembled in pairs sandwich-style with stiffeners in the middle (maybe not needed since plywood is already glued in a staggered pattern) and between those stiffeners I'd slip in foam for thermal and acoustic insulation, especially between bedroom and salon, and between salon and cab.

Another issue: with movement, materials shift, so you have to install the partitions with clearance. I thought of a rail system, or fixing with joints, etc., but I doubt it would be easy to implement.

For the 3 doors (salon cabin, salon-bathroom, and salon-bedroom) I'm thinking of SNCF toilet doors (not the Corail ones with pivot hinges, but like TER ones)—anyway, I'm going to check with the SNCF to get toilet doors and partitions from decommissioned trains, as it's good material.

For the bathroom, there are ready-made cabins available, but is it better to build it yourself?

And that's where I'm looking for advice on all of this.

Thanks to anyone who can shed light on this.

Hey there! We've got our S53 at the end of school holidays—we'll see you anyway on May 1st. We're hoping to get our license by then from Chazot (thanks Patrick!!!!!!). There was a cancellation for the dates we needed, and if that doesn't work out we'll need a driver for the trip!! (what a mess). Plus, we're going to start an association for people like us here who have converted buses, and why not organize a gathering soon? You've got the motorcyclists, the CRS, so why not buses😉

Association: madmax? magikbus? we'll see... what do you think??!

I'd really like to get involved in a tekos as soon as I have my motorhome, but my vibe would be more like cartoon-style music or disco rock—like what I saw at 2 or 3 booths (out of over 200) at the Chambley teknival in 2003.

What do you think?

Hi, I'm looking for fairly large water tanks around 300–400 liters, but my searches haven't turned up anything... where should I look? Or can someone advise me? thanks
SP Sputnick Regular ·
For water tanks, we've already covered this: there are RV shops but they're expensive. You can salvage big PVC pipes and caps to put on the roof rack, or get commercial vehicle tanks from auto wreckers and set them up yourself with baffles. No more than 100L without baffles. You handle it by welding sheet metal, but that's reserved for welding pros. Indeed, it's the hardest thing to weld...
CA Cateludo ·
There's also this solution, which is easier if you live by the sea - boat-building yards are used to making custom tanks for boats. I've already tested it successfully😎

Can someone respond to my request from the 25th (the long post on page 22)? I need insurance that covers people without a license when a friend with a class D license is the main driver.

Hi, and thanks in advance

Hi François.

I managed to get insured at Mascotte even with less than 3 years!

Don't give up, call collective insurance companies but tell them as little as possible about your vehicle. The less they know, the better...

Hi there, I’ve sent about ten emails to SNCF to get the contact details of companies that take used equipment, but they haven’t responded. If any of you have a contact, I’d be interested in those details. Thanks!

Hi there, well why not: "impose your style"... you know a lot of techno music borrows tunes from cartoons! I think you might find what you're looking for! Great combo, right?

Hi there,

For your tanks, a cheap solution is to use heavy-duty diesel tanks (some are partitioned) and clean them with special diesel detergents—like the ones tank repairers use to weld without blowing things up.

You can get a 500-liter tank with mountings for 50 € (just secure it in the storage compartment), plus the swan neck for filling and the threaded connection at the bottom (normally used for draining).

No rust issues since they’re stainless steel—yes, there’s water in diesel, just a little, but it’s always there, which is why there’s a sedimenter.

Pick one with an immersed diesel pump (don’t use it for your water system), so you’ll have an inspection hatch!

Then, to fill up, just open your storage compartment.

Same goes for wastewater.

Hi Patrick, hi everyone. It’s finally happening—the project to remove the seats and other unnecessary accessories started today. Aluminum/polyethylene sandwich panels are arriving Monday to start boarding up the windows. 😇 I’m over the moon!!! Have a great weekend, everyone, Ludo. 😉
DE DebetdimFE ·
Hey there! A little tip for water storage—we’re going with 1000-liter food-grade tanks (white, with a grid around them). It might be a bit tricky to fit them if you’ve got small storage compartments, but we’ve got an advantage with our bus: the engine’s on the right side, so we’ve got space to slide them in at the back by removing the step where the rear bench rests. Classy! There you go. 😎
DE DebetdimFE ·
It's me again! I forgot a small detail—you can find them everywhere, like in factories or other places that are closing down and getting rid of them, or more simply in classified ads for a lower price. Seriously, happy hunting!

I'm looking for a 10-meter-long coach that doesn’t consume much fuel, is easy to homologate, and isn’t too expensive to buy or maintain... If you could recommend models to look for or avoid, that’d be great... I saw a Magirus Deutz R80, but apparently it consumes 30L/100km, and right now I’m looking at an Iveco by Heuliez, an H80 with only 18L/100km fuel consumption. It’s a Fiat engine with just 40,000 km, but the body has 380,000 km... If you could share your thoughts on these two vehicles too, that’d be awesome... And if you have any tips, don’t hesitate—thanks everyone!...........

Watch out, debetdim!

These tanks aren't partitioned!

Your vehicle won't be approved for roadworthiness inspections!

The tanks must be partitioned into segments of 100 liters max (baffles).

HEY CATELUDO

Why aluminum sandwich panels? How do you plan to install them? (welding, replacing the windows, etc.)

Watch out for expansion! This product we use a lot in trade-show stands has a high expansion coefficient and can't be used to replace windows or glued and riveted onto a sheet-metal body. Dibond or Alucobond (the sandwich panel) has an expansion coefficient over 1.25, meaning if the temperature changes by 40 degrees, a 1-meter panel measured at 0°C will measure 1 meter and 2.5 millimeters at 40°C. So if you replace a 2-meter-long window, your sealant, glue, and rivets need to allow for 5 mm of play!

Impossible!

You need to use sheet metal and reinforce it with frames if you want to fit it into the joints, or weld crossbars into the bays and attach the sheet metal from the outside if you want to weld.

If you want to chat more about it, call me at the number in the third post of this discussion space.

Hi Patrick,

According to this site: http://www.alucobond.com/french/produkte/alucobond-spezifik.htm (ALCAN),

Alucobond has an expansion rate of 2.4 mm/m per 100°C temperature difference. So for a delta of 40°C, that’s just 0.4 * 2.4 = 0.96 mm, or about 1 mm for a 1-meter panel. It’s safe to say that on the diagonal of the panel, you’d need to account for 1.4 mm of expansion.

What would worry me most about using this material for the window frames of a bus is the "bimetallic strip" issue. The external and internal temperatures of the bus won’t be the same—at least, I hope not—and so the two sandwich panels, separated by 3, 4, or 6 mm depending on the model, won’t expand the same way. This could cause deformation inward in winter and outward in summer. Though, a bus with variable geometry could be fun ;)
