105mm HE dimensions


#1

Hello,

Does anyone have a drawing of a 105mm HE shell with dimensions? I’ve not been able to find anything online. The one that did look promising was a mislabeled 122mm.

Thanks,
Darren

Darren, you are talking of a howitzer projectile or something else?

Here the M1 HE for the howitzer:

Howitzer - perfect. Thank you.

I have an empty case and it is extremely unlikely that I will find a real projectile for it. So, I will print one.


#5

3D model done. I will print it in four pieces and they will all screw together.

That’s a quick modelling job! Please share the end result too.

Thanks tennsats,

The modelling part is the easy part. I draw one half of the projectile and fuse, add in the break points and then rotate the drawing 360° around the centre line. Add a few chamfers and threads and all done.

Printing, sanding and painting will be what takes the time.

I am curious how the result will look. Please show us later.

The fuze you may want to replicate is the M48. Maybe you can adjust the details to fit this one:

As for the paint job there shall be plenty of reference images in the web.

Thanks EOD, I’ll revise my drawing.

Throwing the paint on won’t be difficult but I will need to think about how I do the stencilling.


#10

Updated model with the M48 fuse as suggested by EOD. Also did a render of what it may look like once finished (minus the markings).


#11

Looks good! Maybe you can look at the coloring or the shells in the internet images. They are more olive green (dull or silky).


#12

Thanks EOD - I’m limited to the ‘stock’ colours and textures in the software and I cannot be bothered making my own just for rendering the model. I’m going to paint it OD green once it is printed. However, I have a batch of other prints in the que.


#13

No worries.
Anything ammo related would be great to see once you have it done. Just for curiosity.

Just to have it said, when you have access to someone with a lathe you may get the driving band turned as a ring and omitt the space in your print and then install it so the projectile will look like an original - just much lighter.


#14

I’ll definitely post some pics once it is done.

Fortunately, I have a lathe and a mill and had thought about turning up a drive band, as I have done these for 20mm - 30mm rounds. However, a friend of mine found some copper paint which not only looks good but tarnishes with age. I’ve always been a bit sceptical of ‘metal’ paints but I was really surprised with the results. They are graffiti paints made by Montana Colors.

In fact, I had initially thought about machining up a projectile using heavy walled tube but it is simply too much effort. Large projectiles are hard to find here and expensive when you do, so depending on interest, I may print up more and sell them. There are a lot of empty 105mm Howitzer cases sitting in houses…

I’ll have to look into flexible filament, so I can print wrap-around stencils.
