Thread: Vickers Bl 8 inch Howitzer cannon of 1917
22/04/2019 21:04:41

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 .....

Thanks Mal.

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 Mal.

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.

Thanks Mal.

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 .....

Thanks Mal.

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 Mal.

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.

Thanks Mal.

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 Mal

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.

Hi all small update on the Bl 8inch Howitzer ,one outer rim complete does not sound much but this took me some time to get done 32 strakes 124 rivets later and I think it looks about right , now to get other one done couple of pictures below on how it looks.

Thanks Mal.

Hi everyone ,bit more on the Howitzer build thought I would make the wheel hubs before starting on the strakes and all that riviting , so started with a 60mm dia steel bar bored out to the size I was looking for then turned the outer hub ends x4 with a round insert tool,and for the outer edge used a end mill with lathe in reverse to give me the nice round edge, after that it was the hub centres which were just parting off tool stuff.After working out measurements and placing parts together I think its looking about wright ,mill the slots for the spokes next and they are done ,,couple of pictures how it all went .

Thanks for the interest Mal...

Hi all,small update on the Howitzer ,first off thanks Mick for the complement but magnificent,i'am not even in the same ball park as the builders on this forum i'am just having fun in the shed. Welded the T rings into the rims and a bit of grinding and clean up with a flap disc the result looks good to me, then into the lathe to divide up and mark the 32 strakes and 16 spokes on each wheel, plenty of riviting in the next couple weeks for me here are a couple pictures how it went .

Thanks for your interest Mal.

Hi all, that will look good when its done Rich will be nice to see a picture , bit more progress on the Howitzer build sorted the middle cross member and cut the radius trail parts to the wright length [ the corner parts not sure what their called } , next part to be made on the trial are the stub axles but before i have a go making them i thought it would be better to make the wheels first ,so rolled some 4mm plate for the rims and welded them up then into the lathe to trim them up ,milled the T rings out of the same plate and tried them together now to grind an edge on the t rings and weld them in, couple of pictures below.

Thank for your interest Mal.img_20190225_211446.jpgimg_20190301_182617.jpgimg_20190301_182726.jpgimg_20190302_184624.jpgimg_20190302_172806.jpgimg_20190302_190333.jpgimg_20190302_190727.jpg

Nice shell. Here's a 12.5 inch RML paperweight I have been making.

Regards Rich

Hi Rich, looks like you got the shape to that bang on nice work , just had a little read up on this and as you know and i think it is a 800 pound shrapnel shell fired from a 38t gun the howitzer was a 200 pound shell obviously a hole lot smaller,are you going to but the brass coloured plugs in it that pick up the rifling.

Thanks for the interest Mal.

Nice shell - how did you fit the driving band?

Hi Mick ,the bottom of the shell is all brass with a steel collar press on to give the impression of a brass band.

Thanks Mal.

25/02/2019 14:07:47

Thanks for the interest and comments guy's. just had a quick read up on the shell and in 1917 or around that time it reads in the manual. The common steel shell had an ogival head struck with a radius of four calibres , so will have another go at getting it wright.

Thanks Mal.

Well bit more done on the Howitzer trail {chassis},made the other inner side with corners riveted in so not many more big fabrication parts to be made on the trail it's self , quiet a few holes to be drilled and rivets to be done but I think the trail is starting to take shape and a bit of weight to it now ,there's a lot of parts that attach to the trail so I won't seal the trail up in till all parts are made and line up ,couple of pics how the I went about making the inner part of the trail nothing special just some bending of some plate.

Thanks for the interest Mal.img_20190223_160913.jpgimg_20190223_164319.jpgimg_20190223_170844.jpgimg_20190223_175508.jpgimg_20190223_180244.jpgimg_20190223_202516.jpgimg_20190223_211659.jpgimg_20190223_213226.jpg
