Hi Bit of time spent making the pick&handle brackets, the shovel base support and the "oil can" holder. Don't think that anyone has ever worked out if it is for an oil can or something else. Machining the shovel support Hope to fit these next week Cheers Richard

Hi C13 ATU's are less common than others, many were destroyed before they reached the surplus market as the lettering on the main indicator markings behind the glass has been thickly painted with radium paint, and is considerably "hotter" than many other ATU's etc of the same period. Don't even think about opening it up. If you do send it to someone, make sure that the front of the ATU is very well protected and use plenty of bubble wrap for the main body. Cheers Richard

Tomas Jones had had that up for sale for over two years and no takers, in my oppinion it is vastly overpriced, I would say that £500-600 is closer to the mark for a complete fully working installation Cheers Richard

Very nice (probably way outside my budget) Have you got some photos of the interior ? as it would be good to know how it is fitted out Cheers Richard

Hi Jim The engine may be the same for both an MW and OY. The engine performance characteristics required for them are different primarily due to the difference in weight. The performance will also alter depending on the air intake system and exhaust system. I have it on good authority that the correct MW carb will improve the performance of my MWC (which currently has an OY carb fitted) The main way of adjusting the performance for a given engine is the carburettor. Carburettor design is complex, there is a Solex publication that goes into the basics of how to size a carburettor (see link to pdf file) Having done some more research, there is a subtle difference between the OY and MW carbs. The jet sizes are all the same, but the emulsion tube is different (I don’t know what the difference is, but it is different, and hence Solex gave them different part number). Tuning/adjusting the emulsion tube will remove engine "flat spots". Cheers Richard Link to Solex publication http://oacdp.org/pdfs/solex.pdf

Thanks Wally I have done some further digging and have found a 1940 OY parts list, this calls for Solex 35RZFAI/C559 From the Air Ministry publication AP2222 (Book Number 10I/BD3A) 7th ed 1944 which covers MW,OX&OY. The jet sizes etc are 29mm choke. 185 main jet 165 correction jet 60 slow running jet 200 starter jet 150 slow running jet air bleed 85 pump jet (this is on the 35RZFAIP model, P denotes pump) Needle valve 2mm Looking at the 1947 MW parts list, The carb was changed at engine number 12811 From Solex 35RZFAI/C559 to 35RZFAIP/C581, and the jet sizes changed (the C559 is the same as that in the 1940 OY parts list). [Note the P is for the additional pump] The main jet changed size from size 165 to 135 (which is different to what the manual states, but 165 is specified for the 35RZFAI/C559) The naming of the jets also varies, so I am getting a bit confused A later OY parts list that calls for 35RZFAIP/C583 should clarify things, will see if anyone has one of these Cheers Richard

Hi Pete Looking good, did you have much trouble finding a new bearing or are they still made? I use a leather hide hammer and a scalpel to cut round the edges, this ensures that no damage is done to the castings, a ball pein hammer may chip the edge of a casting. Cheers Richard

Hi What is the difference between a Bedford MW and OY carburettor The MW carb is a Solex 35RZFAIP/C581 and theOY carb is a Solex 35RZFAIP/C583 Are the jet sizes different? I think the choke actuator is at different angle Any data on the OY carb jet sizes would be most useful (I have the info for the MW one) Cheers Richard

Hi Is any restoring or has a WW2 RAF Fuel bowser, this may be for you.... I purchased this a little while ago, think that the fittings would be suitable for the power pump on my MWC, but they are too big Hose is 10ft long 2.1/2" hose with 2.1/2" BSP fittings, good condition, no visible damage Appologies for the quality of photos... Dated 18/12/44 What I believe is an Air Ministry Number 4K/2013 (but could not find an Air Ministry stamp) There is another number on it which is probably the manufactureres part number The hose manufacturer is Hall&Hall Ltd the type of hose is Petrolite Open to offers (just trying to cover the purchase cost), can ship to UK at cost, but collection prefered as it is pretty heavy Cheers Richard

Hi Mike In the UK you can easily get imperial tube and rod. Virtually all the angle iron is metric and nearly all sheet is metric. You can also get some imperial bar, but this is generally in short lengths. You can get most brass items in imperial or metric, I think that this is because a lot of model engineers work in imperial units Cheers Richard

Hi First attempt at making the dataplate for the power pump and made the bracket etc. for it Cheers Richard

Hi Finally? finished re-building the power pump (just a few cosmetic bits to finish) I can see why a monopump was preferable, much easier and quicker IMG_7193.MOV Cheers Richard

Hi Mike No problem, feel free to ask questions... The original ones were cast, but mine is made in two parts, firstly the main barrel of the piston is machined with a cutouts Then a blank is made to slot into the gap The blank is then machined with the slot for the lever The two parts are then soldered together and then machined round I use FreeCad to do all my drawings, I will e-mail you the CAD files for you to play with (these files are for reference, I did make some adjustments to make machining easier) Cheers Richard

Hi John I will be there, but I don't think the MWC will be all finished by then, still have plenty to do, but I am in the home stretch and the end is in sight 🤞 Cheers Richard

Hi Sadly no, but a friend of mine did make some good overall drawings for me, I used these and the sectional drawing from the manual. I used thes to make better drawings like this so I could machine it. I have made the wall thicknesses a bit bigger than the originals as the original pistons did suffer fromfrost damage as shown in the photo below. (note the crack in the piston body) The differences in walll thickness will have little difference on the pumping capacity of the hand pump. I can see why they would prefer to use the power pump. Cheers Richard

Hi - I have ony just recently been able to get to my truck, but in the mean time I have been busy making bits. The most difficult bits to find for an MWC are the pumps and filters. In the first lockdown I made some replica filters, in the second lockdown I decided to make the hand pumps. Today I gave one of them a test.... They are made as close as I could to the original specification. I had originally made the barrels out of aluminium, but brass and aluminium and water don't go well together. The aluminium ones look the part but aren't function and will find good homes in due course Trial fitted on my MWC These are the aluminium ones The pistons are the most difficult bit to make as they have internal valves Yesterday I tested the first one at home... IMG_7178.MOV Worked well Cheers Richard

Hi You may be able to find a "modern" one, what thread is it ? Cheers Richard

All looking every good.... at least you didn't use the dishwasher 🙂 Cheers Richard

Beat me too it......... My local glass merchants cut new laminated glass for my closed cab MW, the glass merchants should also be able to "chamfer" the edges Cheers Richard

All The HMS Collingwood Heritage Collection/Museum has closed after nearly 70 years of existence. The Collection and its archive is to be moved off site to a new, as yet, unspecified location. At its future location(s) it will come under the management of the National Museum of the Royal Navy. The collection is being moved so that the space it occupies becomes “… a Centre of Excellence, which will be used by trainees and trainers alike working closely with the training provider[ Fisher Training Ltd]…” http://www.rnmuseumradarandcommunications2006.org.uk/ Sad to see another museum going - I have helped out there for the last 8 years Cheers Richard

Very interesting - thanks for sharing Cheers Richard

Hi Keith Thanks for posting those... They have confirmed a couple design assumptions about early Bedford MW's and MWC's Cheers

Hi The Oil Can holder looks correct I think that the oil can is commercial post war?, think it should look like Item 37 Cheers Richard

Hi I have one and it is a nice set and works well, covers 2m,4m & 6m in the amateur bands, the only manual I could ever find is AESP 5820-F-299-201 , which you now have. I use it standalone and have never found the harness that it can fit into, think I have a spare stubby antenna for it somewhere (there is a nice label on it stating stand 0.2m away due radiation hazard) Like some of the other recent military radios they will be virtually impossible to repair. Cheers Richard

Hi As you probably know Phil Bashall is retiring and is selling up all(?) his stock, this is being done by sealed bid auction see https://auction.dunsfold.com/ Cheers Richard
