Underslung toilet cassette holder - has anyone 'designed' one?

[MisterB]

Fiamma used to do a 'Porta Kassette Toilet Tank Container' which screwed up under the floor and cost around £160, without the spare cassette. Unfortunately they appear to have been discontinued and, although a couple of sellers still list them, they have no stock and no idea if or when they might be available.

ive just watched a youtube of someone fitting the 'container' and it looks quite over engineered, for what is basically a box.

has anyone actually made their own underslung carrier or am i off to the land of self design .... LOL
as we dont need or want to carry it at all times, i am a bit loath to take up locker space, but carrying it underneath might mean we carry it with us at all times, with little inconvenience (pun intended)

i am thinking a waterproof material bag (to protect the seals etc, not to stop spills) and a couple of brackets to hold a tray under the chassis could work and the cassette secured on four sides, with one side 'removable' ... i suppose a plastic container secured to stop if falling off the try might also be an option. Of course access to the tray would need to be reasonable, but i dont see it being used that often, that it becomes a hindrance. A sliding drawer/tray fixed through the side skirt would be brilliant but not sure how achievable ..

though if anyone has actually designed their own and is happy to share, even better ......

I made a spare cassette carrier that is fitted under our van Dave.

The base of the tray the cassette sits on is made from 2mm chequer plate. I used chequer plate as the process of stamping in the 3 bar chequer raised sections work hardens the aluminium making it stronger than standard aluminium of the same thickness and it's cheaper. The aluminium angle to locate the loo cassette is just riveted to the chequer plate.
I used existing holes in the chassis rail to rivnut and bolt a length of 50mm x 50mm x 5mm aluminium angle to the chassis rail and on the other side I bonded and screwed a length of 150mm x 6mm aluminium plate to the inner of the vans side skirting. I cut out a lot of the aluminium plate to reduce weight, as it was only each end that was being used to locate the front and rear rods.
I put the cassette in a black dustbin liner to keep the road muck off it.

Thats perfect Paul ..... just what i needed - especially as i am sat here waiting for the stitches on my head to dissolve, I'm banned from actually doing much fettling at the moment as ive banged my head twice already not being careful and nearly opened the cut up first time i did it !!

is it easy to bend the checker plate if i went for 1.5 mm thickness and then i could dispose of the additional L brackets along the sides and ends, by bending it into a box type tray? i was thinking about making it 100mm bigger than needed, which will give me a 50mm upstand on each side and end

I was just thinking, access for the empty cassette is one thing but putting a full one underneath in it’s place, another thing altogether. Two on Tour ‘s hinged solution is ideal.

You could bend 1.5mm checker plate, but how cleaner bend you would get without a bench mounted folder is a different matter, but to be honest, I think it would be more hassle than riveting L brackets which you would have great control of accurate positioning to hold the cassette in position.

A full cassette weighs around 20Kg, but the cassette wheels help to get it onto the tray.
As I get older and weaker, I will probably add a length of aluminium tube to the tray as an extension to get more leverage when lift a full cassette into the travelling position.

This is the initial plan, it doesn't have to be pretty lol !!

Make sure that you buy at least a couple of extra sheet of checker plate, as it will take probably a couple goes to get your cassette holder right or to give up and go my route, but I hope that you prove me wrong.

I spent 6 years as a sheet metal fitter-welder, making power station control consoles and switch gear cabinets and I have a bench folder, but opted for the easy option of riveting on the L brackets.

i am sure anything i do won't be as good as you could do with your background, but im happy to have a go. perhaps you should start making the trays using your equipment and selling them as the fiamma ones dont seem to be available anymore .....

im even tempted just to use flat aluminium as i really dont need the strength of checker plate as im sure the folding might add sufficient strength - even potentially rivetting the corners would add strength......

as you can probably tell, im throwing ideas out there for comment before i start ordering - its going to be after christmas before i start.

I made mine out of a big oblong washing up bowl.It's held up by clips on a short lanyard one end, and a ratchet strap the other.
On the slightly lower end I drilled a couple of drainage holes.A piece of softening around the emptying neck where it pulls up against the underside of the floor, and alls well. I don't even take it off between trips now, and it's not visible behind the skirt unless you get down on your hands and knees. I made similar on the other side of the van that houses mud mats, and some timber baulks.
I'll pop a couple of photos up,but it's dark out side now.

I think that you should get good results by clamping sides of your tray between two pieces of timber like CLS, which will give you a radius on your bend, plus help it round with a lead shot loaded soft plastic mallet. When you have bent two sides, you will then need to cut the timber to the width between the two bent sides to be able to bend the remaining two side.

Ho no!
Another project to contemplate with better weather in spring.

yes, but im sat here bored to death, so inventing projects that i dont actually need to do is killing the time until i can start some of the jobs that dont involve me banging my head and opening my cut up !!

Paul, ive had a rough estimate of £65 inc delivery and VAT for a tray to be fabricated out of 1.5mm checker plate .... it seems like a fair price to be honest, any thoughts?

if anyone else is interested and the 'design' works out, i can always pass his details on .....

That seems very reasonable to me Dave, considering hourly rate and tooling setups for forming the bends.

Any solution that works is a good solution.

What about using something like the wind up system of the spare tyre that can go under the van to pull up the cassette ?

Then something like a couple of hammock straps connected to the wind up mechanism

And before anyone offers him one because you have a spare one hanging about ................. I m looking for that exact one on advertised for a ducato !

I'm hoping to pop over to let him take some measurements and potentially for him to offer some advice or a better solution. I did think the price was reasonable to be honest and as you stated, any solution that works is a good solution...
