|Thread: Vickers Bl 8 inch Howitzer cannon of 1917|
Hi all, bit more done on the Howitzer cannon removed the ugly welds holding the wedges in place cleaned up around the trail, drilled some holes and now one side can be bolted on, used 4BA bolts for this thought they looked a bit out of scale at first but placed the wheel on and I think they look about right what do you guy's think.
Thanks for your interest Mal.
Hi all ,another small update milled the second axle wedge and the wheels all measure up good and straight to the trail , this was my main concern because if the trail was out of alinement this would show up in the wheels not being square to each other and the trail looking off centre, so next is to grind and clean weld marks get some bolts in them and the trail will be sitting on it's own wheels.
Hello all, sorry to those following this build for the lack of progress on the Howitzer cannon but it;s because of work commitments which are taking up all of my shed time ,anyway managed a couple of evenings in the shed last couple of nights and thought i would tackle the part in the first photo, it's like a wedge which goes in between the stub axle and the trail so that the wheels line up straight , so tack welded a 6mm plate to the trail and set it up in the mill ,the welds will be taken of and replaced by bolts ,couple of pics below on how i got along.
Thanks Dave, but after looking at the pictures I think the depth on the hubs looks about right but the diameter is still slightly to big so Will take another mm of and see how that looks

Hello all, small update on the Howitzer build after a couple of attempts making the wheel pulling ring and cap to about the right size I settled with the one pictured below, next to drill a hole through the cap and fit a pin to hold it all together. I think next on the build will be the wheel braking bands.
Hello all, small update on the Howitzer not much done as work and garden has been sucking up all my shed time, managed to finish the basic pair of stub axles plenty more to do on them yet like holes drilled and cut to length etc, next will be the trail wheel pulling rings and hub caps.
Thanks for the interest Mal
Thanks for all the input and thoughts guy's .Dave after reading your info on the history of Howitzer cannons I think your right, the cannons were probably updated from the first one that seen action, so to build a true replica of the Vickers MKVI Howitzer would be impossible so on that note its fair to say that what i'am trying to build is a representation of an early U.K version of the cannon based on the web ,photos and small bits of video to the best of my ability,so Dave,Neil your right and I will stick with the axle that i'am building.Simon,Mick now that would be something. Niloch very interesting watch thanks for sharing.
Hello all ,next part on the Howitzer build are the stub axles ,now started on the first one going on the drawings in picture 2 and all was looking good to me, until I looked at a couple of pictures where I noticed the hubs look a different size, maybe it's because the one in the picture is a later model made in the U.S and the one in the drawing is an early model made in the U.K ,what do you think go with the one i've made or back to the drawing board and have another go with different sizes to match the stub axle in the picture.
Very interesting read Clive thanks for sharing, learning more about this subject than I ever thought .
Hi all, interesting reading guy's. DaveD the Howitzer mk VI had a range of 10,745y ,,9,825m and a barrel length of 14.7 calibres 117.7 inches [which is the one i'am trying to build ], now the mk VII and VIII had a range of 12,300y but the barrel length of 17.3 calibres 138.4 inches . I think Mick has this right and its just down to the barrel. Managed to get some more work done on the wheels last couple of days, hubs in place and rivets on the wheels finished next a bronze bearing in the hubs ,couple of picture below to see how things look .....
Hi all thanks for the info and import on the Howitzer cannon, Dave the cannon in the picture is a howitzer mk I to mk V and weighed in at a heavy 13.5 tons [first two pictures below] ,Niloch the howitzer cannons were moved around with tractors with the caterpillar design,traction engines [last picture] horses [the pulling ring on the outer part of the hub was used for] ,I think the soldiers at that time would use any means to their disposal. The Howitzer that i'am trying to build is a mk VI to VII [bottom two pictures] which was a lighter cannon and weighed in at just under 9 tons, first gun rolled of the assembly line 1 march 1916 still moved around by the same means earlier on in WW1 ,when compared to the earlier versions it had a better recoil system but still needed ramps under its wheels to control the rest of its considerable recoil, i'am no expert on these cannons its just what I have read up on them before starting the build so i could be wrong.
Thanks for the interest guy's ,after pulling the traction engine out and placing it together on the bench with the Howitzer it makes think how much there's to do, all good fun though. George there are a few parts on this cannon that's going to be a first for me the breach block being one of them so looking forward myself to having a go at it.
Hello all ,well got up at the crack of dawn today and in the shed well before 7am and managed to get one set of spokes done on one wheel except the outer rim rivets and the outer parts of the hubs,after getting the spokes on the one wheel sorted and placing it together with the trail to see if every thing looks about right I decided to dig out some parts of the 2" minnie traction engine out that i'am in the middle of building .And that's when I got a bit carried away and placed the traction engine together with the howitzer which is about 2" scale and also got carried away with taking pictures, but what the hell here they are .....
Hi all ,still on the wheels been busy milling the spokes for the last few days did think about getting these laser cut but where is the fun in that ,so all 32 spokes done and milled the slots in the hubs, now to put all parts together and make a wheel, couple pics below on how i got along .

Thanks for the interest guy's , mill some slots in the hubs and make some spokes is the next step on the Howitzer build.
Hello all, small update on the Howitzer build finally finished the wheel rims which seem to take an age to complete, I found it a little more difficult than the 2" rear minne traction engine wheels as the strakes have a rivet head on both sides on the full size gun and not hammered flat into a countersunk hole like the traction engine wheels,every eighth strake has a larger hole with the rivet missing for a bar to be inserted for leverage to aid movement of the traversing movement when on the firing platform, here are couple pictures to see how its looking.
Sorry tried to but a link to the video but nut sure how, the video is ,,Armaments Manufacture R3/3 220740-04 Footage Farm . AdrianR good point could well be down to that.

Thanks Dave, Maurice thanks for your input and your right I have looked at many pictures before I started building the wheels to see which way the strakes are angled and each picture has them different on the vickers Bl 8 inch mkVI , think i have just about seen every picture the webb can offer, but I came across this youtube video which has a short part of the gun on the factory floor, so I based the direction of the strakes on this, here is a link its at 8.59 on the video.

Thanks for the interest everyone .Maurice on the wheels the manual reads that the slats or strakes are for grip on soft ground, but looking on the way the slats are angled would bush the wheel inwards to the chassis on firing rather than trying to force them outwards, I mite be wrong but if anyone knows different be nice here.
