Progress on the Ruston & Hornsby 1ZHR

[mike90045]

such tiny tires for a heavy load ??

[listerdiesel]

Hi Mike:

The trailer all-up weight is 3500kg, the max tyre load is 4380kg, 730kg each, so we have a bit in hand.

Tyres are 175R13C, load rating 97, Hankook RA08 light van.

The bare chassis as in the pictures weighs dead on 800kg.

Things have moved along quite nicely:

Update from Monday:

Lots of things happening today, I arranged for another brake cable to be here for the morning, that should enable things to be finalised on the brakes.

(The issue was the anchor point of the cables. If behind the pivot point on the drawbar, ie on the swivelling part of the axle, the tension on the cable will vary with the bending of the joint in the drawbar, that was what was niggling me the other night)

The windows turned up, so they went in pretty quickly, no big problems and they are nice quality. Fairly heavy, but so was the whopping great lumps of GRP/Ply that we jigsawed out.







Makes the interior much more comfortable and every window is ventilated with a top 'hopper' vent, so I haven't got to rush to fit the roof vents now



Also you'll note the white box alongside the loo/shower window, that is the external power inlet box and socket.

All wired in but can't find an extension lead here for the mains! :embarrassed:

Update from 06/06/2011:

A few pictures that I took this morning after it stopped raining:

Drawbar Parking


Internal Electrics


Winch & Batteries


Finished Bulkhead


There is an external power inlet to go onto the trailing blue cable, we just hooked it up to give the batteries a charge.

I just have to ask.

You guys that do this perfect work also usually get a lot of it done.  Did I just stay home and watch too much daytime TV as a kid or was your finger painting also post-impressionist with subtle overtones of cubism?

Too bad NASA didn't get you to do the shuttles.  They'd still be ready for another 25 years service.

Bravo Mr. listerdiesel.

That is a thing of beauty! Looks like a million bucks!

Here are a few images of the beast parked outside the factory the day before we left for Holland and the Nuenen engine show:









Here is one of the rather nice and rare engines at the show, a Thomassen gas engine:



Have been to Holland and back, no trailer issues at all, and the Ruston 1ZHR ran for two full days without a stop.

Concepts are great, and can take a lot of time, but if you think that is bad, actually producing something like this is a whole lot worse!

There are about 30 separate drawings for the various bits and pieces, and some of those run to 6 or 7 issues. It didn't happen quickly and there were many compromises along the way. The cooker, shower, toilet and fridge still remain to be fitted, plus the Autogas refillable LPG tank and piping. We are very pleased that it has turned out OK and that it tows very well, better than expected.

We also need to take some weight out of the trolley that the Ruston sits on, we have to trim 1/4 ton somewhere.

What a great job Peter, engine and trailer !!

[Apogee]

Stunning Peter!

I would like to order a 40' version.  Would you mind tossing in a big screen TV and hot tub?  Also, would you be available to deliver it here in the US?

In all seriousness, beautiful work!!!!

Are the sides one continuous piece of the foam material or does it come in smaller sheets (it's hard to see seams if they are there in the pics)?  Also, what is the roof made of?  Again, one continuous piece?

Lastly, I love the folding hitch idea as it cuts down on the overall length nicely!

Just a fantastic job!  Can't wait to see the finished pics of the inside as well.

WOW!

Best regards,

Steve  ;-)

Steve:

The sides are sheets of 14mm GRP/Ply/GRP sandwich, the honeycomb was used for the flooring and the bulkhead between the living quarters and the engine.

The side sheets come as one piece, and even after we had cut them down to size and cut out the wheel arches etc., it still took 4 of us to pick them up and put them in place.

The roof comes on a continuous roll of 1.3mm GRP. It is riveted to the cant rails all round at 220mm centres, and stuck to the roof bars with double-sided tape.

Bit more work done over the past week or so, we made up the false wall that the cassette toilet sits on and got that fitted into place, 120mm forward of the actual wall/divider.

We have a huge amount of GRP/ply and honeycomb left over, so it's just a case of picking a piece that's near enough in size and trimming it up. Two bits of 3/4" angle were used to fasten it to the outside wall on one side and the new kitchen side wall the other.








There is a 'hook plate' that the toilet sits onto, and there are three screws farther down which are going to be fun to get in. The whole assembly sits on a styrofoam padded base, and we have raised it up by 15mm so the outside cassette access door will clear the side rave extrusion.

There is a path under the shower tray edge, under the toilet left-hand side and through both walls for the hot and cold water hoses and anything else we want to run from front to back.

Pictures are a bit wishy-washy, didn't take them until after dark.

We have the covering extrusion for that big join in the divider, and are planning to fit that tomorrow evening. The screw heads will be this side of the wall!

Peter

Edit:

Got the extrusion fitted over the bulkhead gap, and reversed the screws so that the smooth heads are the bathroom side.

 The H and corner extrusions arrived today, not particularly cheap but exactly what we need. The supplier has a minimum order charge so we just added more extrusion to make up the price.

Cut that tonight and had a trial fit of the panels, looks OK but we have a 1mm panel width difference between the channel and the panel, so will need to address that.

 Went through the cassette toilet templates again, had to do a bit of patching up of old tears etc, but we have now made some sense out of it all and expect to cut the aperture on the weekend.

Edit 2:

Spoke to Thetford again about the new templates for the toilet, they say they will be here on the 27th. The set we have don't match the outer door, and I'm leery about cutting a big hole in the side without knowing it's going to be OK!

Are the sides one continuous piece of the foam material or does it come in smaller sheets (it's hard to see seams if they are there in the pics)?

Here are a couple  of the pictures of the sides as we were cutting them down:





The second shot is the 8ft X 8ft panel for the front.

Part of the current work is to lose about 600 lbs weight from the engine, as the trailer is slightly overweight.

The 6-wheel trolley that is under it now has to go, and we are making up new axles with wheels from a 1940 Bren gun carrier (Universal carrier) made by Ford Motor Company of Canada.

Here's a few pictures of what we have been making up recently:

Carrier wheels after being fired to remove rust and the remnants of the moulded-on tyres (molded-on tires)



Axle beams and stub axles:



Stubs about to be welded into the tubes, each one is 2" diameter steel, with an 1-7/16" hole drilled up the centre to save weight:



Axles almost finished, turntable disc and pivot bolt to go on one of them:



Disc welded on, just waiting for the M30 bolt:



Painting the wheels after shot blasting and Zinc spraying:



Glueing the tyre strips on:



Tyres all stuck down, just need trimming and wheel bearings fitting:



Tonight's efforts, chamfering the tyres and fitting the wheel bearings:
