Thread: Vickers Bl 8 inch Howitzer cannon of 1917
04/06/2022 10:15:32

Hello all, managed to thread the breech plug last couple nights which all wen't well up up to the point of trying the breech ring on, the breech ring didn't want to go on first couple of attempts so bit of shaping here and there with some needle files and it screwed into place,the plug and breech are in scale with the Howitzer except the o/d of the breech ring which is about 25mm smaller,next is to get the plug to swing into the breech all good practice before I make a steel one which will take a lot longer, couple pics on how it turned out.

Thanks Malimg20220525221250.jpgimg20220525221313.jpgimg20220603123641.jpgimg20220603123649.jpgimg20220604094041.jpg

Hi all, managed to broach out the shape for the plug the last couple of nights, next will be the threads and to see if the breech and plug will fit together, a couple of pics on the plug before I start with the threads.

Thanks, Mal.

HI, well cut the threads as Dave describes a couple of posts ago and all was going well in till I forgot the depth then things started to go wrong, so too many spring cuts were taken to clean it up so I think the threads are out of pitch, will carry on with the plug to see what comes of it.

thanks Mal .

Hello all, well the second attempt at the breech block is underway, all this is practice and to see if I can do it so decided to have a go at the breech in aluminium before cutting metal to save cutting time if things go wrong, this attempt will be in scale with the Howitzer that I am trying to build, managed to broach out the blank in the lathe now for some threads couple pics to see how it looks.

Thanks, Mal.

Hello

Not a very good picture here but you can see some of the undercuts or relief cuts to allow for the plug to swing in.

Hello all.

Richard that is a fantastic looking model of the PAK 40 very impressive and detailed nicely, good size as well at 17" thanks for sharing.

Peter couple of pictures on here when you start the build would be very interesting.

Mick thanks for the offer but will keep it as a model.

Dave that is pretty much how I went about it, although the cut outs in the breech would never work with a swing-away plug. So I have been trolling the internet for a good few days now and am about to start my second attempt, Ady1 it sure would make it easier to have a sliding plug.

Thanks, Mal.

Forgot to mention this was not in scale with the Howitzer in size or the number of threads just a practice run at trying to figure it out , lots of lessons learned by trying so will see how the second attempt will go.

Thanks Mal.

Hi all ,well no room for the Howitzer in the shed at the moment so thought I would have a go at the breach threads which went all wrong towards the end, not realising that the dividing head had slipped and managed to brake of the tip of the cutting tool with out realising that it had so this being a total fail but second attempt will be started soon, thought I would put up some pics as not posted in a while even if its a failsmileyimg20220510204145.jpgimg20220511142429.jpg

Hello everyone, I have been working on moving the shed about and making it bigger ,haven't done any progress on the Howitzer since the last post but will start up again as soon as thing's are sorted. David may be next year when the build is a bit more together.

Thanks Mal.

Hello all

Thanks for the comments and interest in the Howitzer build ,Richard the pak40 would make a very nice model what sort of scale are you thinking of building it in .

Well small update on the Howitzer build not really got much more done than the last post not down to shed time but everything I have made lately I've managed to mess up on by silly mistakes and the part ends up in the scrap bin, what I did manage to make is the carriage bearing and bolt so it fastens from the underside and started on some of the tin work to cover the carriage, couple of pictures below of my very slow progress .

Thanks Mal

Hello all ,small update on the Howitzer build, I have been busy making the carriage frame which supports the barrel on the cannon , this has been made out of 16mm box section cut into various shapes and welded together [fighting the dam heat distortion ]. Next on frame will be to plate over with some sheet steel an rivet on but first I'll try and finish some fixtures on the trail, couple of pictures below on how it's looking.

Thanks Mal.img_20201022_194858.jpgimg_20201025_163503.jpgimg_20201025_165230.jpgimg_20201025_170603.jpgimg_20201025_170427.jpg

Hello all small update on the Howitzer build , now that I have finished the elevating gearbox I thought the barrel carriage would be next so the fixtures to the trail can be riveted in place ,decided to make a jig to suspend the top bearing were they need to be and the distance to the gearbox for the elevating cog ,going to make the carriage around these parts with 16mm box then form plate over and rivet on, made the bearing carriers last couple of days which toe in about 6 degrees against horizontal bar they still need a bit of fettling with to finish them off, couple of pics below on how things are looking.

Thanks Mal.

One more from last postsmileyimg_20200809_001500.jpg

Well managed to get that lump of bar stock to look something like the Howitzer elevating gear box, loads of filing and fettling and now I think it looks about right for an early version design, as I found out on the internet through pictures there are a few with slight differences ,couple of pictures below on how it turned out and how it will look on the trail.

Thanks Mal.img_20200808_233347.jpgimg_20200809_001147.jpgimg_20200809_001208.jpgimg_20200809_001251.jpgimg_20200809_001300.jpg
