Tiger 1 late variant breech

[Vince Cutajar]

I have been following John's amazing build of the Tiger 1 breech (viewtopic.php?f=6&t=2922&start=435). I was always interested in 3D modelling the said breech but could never find enough information / dimensions to make a decent one. Recently on John's build, Chang posted an interesting link (http://metspra.ru/).

I have never seen this site before and was amazed at the useful information I could find there. Best of all it has a set of drawings regarding the breech and all the gun components. Unfortunately all the drawing are in 1/16 scale. Hence the reason why I am posting here and not in the Tiger 1 forum. I decided to start 3D drawing the various components in 1/16 scale. I can always upscale it to 1/6 scale when required.

I am not going to flood the forum with images. Instead if you follow this link (Link removed) it should take you to a web based 3D viewer and view the progress there. Hopefully it will work. One can view various components there. I will try to keep this link active during the drawing process.

Hi Vince,
I was able to open link and view your model. That is a neat feature in F360. I was able to rotate and explode the model. Nice work.
Best regards,
Bob

Thanks Bob for your comments. Yes, the web based viewer is a nifty function. I only got to know about it recently and have been testing it with Phil on his Faun build. It is better than sending images of the model. I only hope that it continues to work properly as the file gets bigger.

Hi Vince
It's is amazing what you can do in 3d

I've done all the parts pertaining to the breech body. One can use the same link to have a look.

Next to be drawn will be the recuperator and recoil components. Whilst looking at the drawings I noticed something strange. The attachment points of the two cylinders are actually bolted to the two sides of the breech body. I always thought these were welded. Internet search for images of Tiger 1 breech was done and some photos actually showed these attachment points being bolted.

So I guess there were two types of Tiger 1 breeches. Another difference I noticed was that some breech bodies had filleted edges whilst others had chamfered edges. Learned something new today.

Yesterday I finished the breech and cradle. Decided to add the barrel and muzzle brake. I used my own 3D model for the muzzle brake instead of remaking it.

Now I am thinking of adding the mantlet for completeness. I guess I am digging a deeper rabbit hole!!

Mantlet finished also. I am not going to add further bits and pieces so I am declaring that the model is complete. Enjoyed the challenge.

I will leave the link to the web-based 3D viewer active (give it some time to load as the file is big) for a few more days then I will replace it with a couple of images.

Made a simple animation of the breech block operation. It's a bit rough as holding camera with one hand and operating mouse with the other.

Well done Vince

I have disabled the link to the 3D web viewer and instead I am posting a few images.

Beautiful CAD model Vince. Your skills have come a long way! That gun looks great.

Thanks Bob. I guess practice makes perfect. As I am rarely going to the workshop I tend to spend a lot of time on CAD.
