Maudslay Subsidy Lorry

Good News with the Maudslay coming on the L2B.

 

It will a unique gathering.

A not to be missed event for those interested in WW1 Mechanical transport.

 

It would memorable if all the WW1 military trucks could be grouped for a photo.

 

I guess this could be arranged at Crystal Palace as there is space but might be a bit early in the morning considering the start times.

 

Does anyone know if the Foden is entered?

I don't think so

An appeal for funding has gone out in an attempt to get it completed in time for the 100th Anniversary of WW1 starting. £5000 is all that's needed. I wish the money I pay to Coventry City Council would fund this. In the general scheme of things £5k is a dip in the ocean ?

From talking to the gents at Leamington at the weekend, mechanically it was good to go, though they wanted the gent who had rebuilt the engine to attend and start it.

 

Otherwise all I could see is that it wants a body and some wings.

Yes, exciting times. They hope to start the engine in the next week or so. In the mean time, here are some more pics of some of the things we have done.

 

One of the lads has made up the fuel tank and soldered it up. It has been tested to 5psi.

I then took on the lamp brackets. These had been bent outwards to accept some bigger electric lamps but we want to fit some Lucas 742 oil lamps.

The first task was to straighten them using some heat and the vice.

It can also be seen that the prongs had been hacked about so I cut them off and turned up some new ones.

After milling the end square, I drilled a pilot hole using a simple jig to align it. The underside is drilled to the diameter of the prong.

Then they were simply silver soldered on.

At this point, it became obvious why the sides of the spigots had been filed off!

A final clean up and ready for painting. One more step in the right direction.

Yes, I did file them off again but not quite so brutally!

 

The engine was finally set up on Thursday and initial attempts were made to start it. It was, not unexpectedly, very stiff and despite having a number of people on the rope, it did not run. I went along yesterday after work and we had another go but it still won't start! Not even a 'chuff' which is very disappointing. It appears to be getting fuel OK but the spark is very weak. The magneto has been checked by a specialist and found to be OK but it is the electrical system which remains in doubt. We plan to try changing firstly, leads, then plugs and then to a known good magneto and see what happens. It will go eventually!

 

After all of that, the engine is noticeably freeing up and one person can swing it now but, gosh, do I ache this morning!

 

Steve :-)

 

Sorry. Forgot to take the camera.....

Is there any indication that it had an impulse coupling originally?

Or maybe a secondary ignition system (like Jez has)? I only see one set of plugs, though, so I assume not.

There is no indication of an impulse coupling and we have just a standard vernier type. I have gone through the Museum stores but with no luck. I have been looking for one for the Thornycroft for when the time comes but they are like hen's teeth, it seems. There are two plug holes in each cylinder but no signs of a distributor of any sort to enable trembler coils to be used.

 

Actually, the magneto arrangement is quite bizarre. One gets the impression that the engine was drawn up and the magneto forgotten entirely! As a result, it is on a bracket bolted to the chassis and chain driven from the front of the crank. Not sure what this is doing to the earthing but we have run a wire from the bracket to the block to try to help the spark a bit.

 

I went along yesterday and the lads were playing with the inlet manifold and the valve timing. They wanted to check that the manifold was sealed properly but unfortunately, broke a stud getting it off so there was something else to fix. They also reached the conclusion that the camshaft was one tooth out so they will have a go at that next week as well. We didn't get the opportunity to try to start it again.

 

The joys of old engines with no manual!

Sorry, no video yet but I have been sent this pic. It works!

It runs well, I understand but is suffering from an oil pressure of 165psi when it should be around the 20mark! The relief valve is due for investigation.

 

I went to the museum a fortnight ago with the magneto we have had rebuilt for the Thornycroft as I knew it's history. I started to fit it but thought I would have a look at the drive key position compared with the contact breaker to see if it needed re-timing or I could just fit it and this is what I found with the key straight up in both cases:

Much to my surprise, the contact breaker cams are in quite different positions and I don't understand why this should be so. The RH mag is my Simms SR4 (clockwise) and the LH is the Museum's Simms SR4LX (clockwise). Can anyone explain this to me? Does the SR4LX have an anti-clockwise cam ring fitted? I looked for alternative fixing holes for the cams themselves but none were evident so it is a bit of a puzzle. Something else I would like to ask is can anyone tell me the difference between an SR4, an SR4LX, an SR4LEo r an SRM4? I'm sure there is a difference but it must be quite subtle.

 

Once my mag had been fitted, the lorry gave a chuff, almost immediately but refused to run further. Since then, the lads have got it going but I won't hear the story until the Shuttleworth Old Warden show tomorrow. The weather is not looking good but I am sure we will find something to talk about! I will post some pics in due course.
