    what am I doing wrong? Is it a gas or wire speed issue ???

     

    Hi

    A couple of observations / comments...

    As you are welding old steel to new steel, the old steel may well have rust and other impurities that will stop a good flow

    Also when welding  old to new steel. The old steel needs to be really really clean, clear of any rust and thoroughly de-greased (likewise for the new steel). If you don't do this then  rust will soon bubble through. (Learnt through experience)

    Also good idea to give welded items a light coat of paint to prevent surface rust, especially important as it damp at the moment. Any small unseen voids can also be sealed with seam sealant.

    Hope this helps

    Thanks for the reply, I think pilot shaft, gearbox bearing, fuel chang over tap, and as you say Radiator cap all for Bedford.

    Hi

    The bearing is from a Bedford Gear Box  - equivalent to an SKF 6307

  3. Hi

    A bit of a long shot, but I am looking to reproduce a data plate for my MWC. The plate relates to priming the power pump before use.

    I was thinking about getting one etched, but I think the etching depth won't be enough. The size of the plate is 2.5" x 2.5"

    Does anyone have one of these I could borrow to make a copy or better still does anyone have one for sale?

    Cheers

    And just to add insult to injury my wife sticks her head out the window, smiles and utters those words “ is it broken “  As you can imagine the reply can’t be posted on this blog 😬

     

     

    Not broken... just re-positioned and re-shaped 🙂

  5. Hi

    This is the connector for the R216 reciever

    IMG_6989.thumb.JPG.6c7c413c538d214ae51fa4b15910539b.JPG

    For the SUR45 power supply you need a free plug of the same type

    The pinout looking at the reciever are

    this is from

    https://www.radiomuseum.co.uk/R216.html

    this web site also has details of a "home brew" main power supply.  I doubt if you will find a SUR45 which has a DC input (think it is 24V), or a No. 24 power supply which is a mains supply one, in either case the the output socket is a plessey Mk 4 12 pin fine thread

    Cheers

  6. Hi

    Been doing a bit of tinkering in the "shed"

    Gun Mounts coming along nicely

    does help having a A0 wiring diagram to hand

  7. Hi

    Not posted for a few weeks, but I have been busy

    I have spent some time making bits for the power pump, the one that I acquired was for an early MWC (see notes in previous posts) and needed some some modifications. The outlet of the pump did not well under the tank and also it did not have a third port for the pressure releif valve, so new top made

    This is the original output (the "Y" is the output ports)

    IMG_6748.thumb.JPG.3b696b61a35a31141e452e5897d6f877.JPG

    and this is the newly manufactured one fitted to the pump (it is not an exact copy but it will do what an original one does (thanks to Tomas Higgins for some additional photos of the power pump)

    Thanks to Pete Ashby for take the measurement of the pressure relief valve, ny truck need three of these , one on the power pump and one on each of hand pumps (still looking for these)

    IMG_6780.thumb.JPG.b5c38d63feef4b658a591d3411db8234.JPG

    I had already made the front pump support,  the rear was proving a bit more difficult as the reat of the pump is 3" in diameter and the clamp width is about 1". On eBay I happened to come across a sanitary/kitchen pipe clamp which was advertsed as a 3" pipe clamp (just perfect I thought), the clamp is american made but made for a 3"BSP pipe. So I turned up an Aluminium split shell to fill the gap between the pump and the clamp.

    IMG_6790.thumb.JPG.7f1875a82de6d8a600a54d4a0d77fa57.JPG

    Welded up a support backet that sits on the chassis cross member, the clamp bolts though into this (3/8" UNC bolts, these are what came with the clamp) nett resut

    IMG_6794.thumb.JPG.63a14719dde9e07654e5f6b52c1e6325.JPG

    Next job is to convert the drive mechanism to a chain driven one. This will unfortunately means cutting the drive shaft as it is a bit too long. The modification I will be doing will mean that it can be returned to its original state at a later date.

    IMG_6799.thumb.JPG.c09711e264bdc38e9e129e8d8f1a71f9.JPG

    Due to the rotational direcion of the pump, all the threads on the end will be left hand ones. The chain is the same as the timong chain that used on a Bedford 28HP (looking for a scrap one of these)

    Next update in a couple of weeks

    Cheers

  8. Hi

    Not much progress this week, limited time at the "shed", but did manage to get the hand pump supports brackets partially made

    IMG_6742.thumb.JPG.6fa30e6d20b4c9dbed4390c229952973.JPG

    Thanks to Pete Ashby for supplying me with pattern for the supports (and some useful photos), hopefully will be cutting the back in the next couple of days and welding them up next week, this is what the should look like

    Next on my list is to attemt to make the facy valves that goes at the bottom of the pump (unless anyone has any of these that they wish to sell),

    this is specially for MWC's as other bowsers have a different arrangement for selecting hand pumping or power pumping. When the power pump is used, the water flows though the hand pump to the filters

    Cheers

    I've had it apart, hoping there would be seals that could be replaced or something, but the main gubbins inside fits metal to metal, and too much of it has worn away over the years.

    Don't know what the internals are like, I assume there is a piston that goes to and frow. Would it be possibe to re-sleeve it and/or make seal on piston ?

    Would be interesting to know what the internals look like

    Cheers
