Nice job Sarah!

I like the fit: very tight, good radii

Thanks

Brian

Hi Guys,

I've done a bit more on my Panzer III, with the armoured cover and securing caps for the inertia starter. Took a while to do, but it's come out quite well, though I did 'practice' :wink: on some earlier securing caps.

Next job is to make some smaller cone nuts for the bottom of the rear hull panel.


Regards,

Sarah

Sarah - real quality machining and you've got the open end right. I'm envious. Your Pz III will be a treat to see.

I hope you have a better idea about completion dates than I do with mine. I'm conscious that Gill and Mark have already decided on the next tank to follow the Comet and that mine will arrive in September or so. My Pz III is giving so much good stuff to do that it might take years to complete. I suppose for some of us, that's the attraction?

Regards

Stephen

Hi Stephen and David,

Thanks for your comments about the cover, I'm quite pleased with how it's turned out.

I don't think I'm any better with estimating completion dates than you are Stephen, as I had expected to have it finished before my Tiger turned up! I am enjoying making and modifying bits for my Panzer III a lot more than I thought I would. It will be nice to finish it, but I do really enjoy the research side and then working out how I am going to make the different bits and pieces. it's a good challenge :D


Regards,

Sarah

Hi Sarah,

I'm impressed with your ability to meet the challenges presented.

Cheers...

Hi Guys,

More progress on the Panzer :D

I've finished everything on the Rear Plate, which includes turning down some brass screws to make three smaller cone nuts, adding Steve's cone nuts, a couple of hex bolts and the cover for where the stater handle goes.

Image

I've also finished the domed cover for the fan belt access. I might try and make some smaller castle nuts for it. It's made in one piece by cutting at the surface at various angles, then using a file and abrasive paper to finish rounding it off.

Image

Image

The sketch shows the four angles which were cut into the domed cover blank and measurements across the cut, to show how far to go. As can be seen on the far right hand sketch, there wasn't a lot of material to take off with a file.

More soon...


Regards,

Sarah

Hi Sarah, I am really impressed with your machining and drafting skills, you make it look so easy, when I made my domed cover,it never occurred to me to machine it from he solid, I just domed a flat sheet and silver soldered it to the back plate
regards
Jeff

Hi Sarah,

Amazing work.
Time for you to get a lathe since you are obviously a serious modeler.

Cheers...

Great looking rear deck Sarah.

I find it very interesting that all the people who have attempted the domed cover have gone about it in different ways :D

Hello Sarah,
I'm keenly interested in milling machine set up procedures. From one who has had no formal machine shop classes and not even a machinist mentor I think set up is one of the most important keys to success. Could you tell us how you hold the part at the various angles and what did you use to get the rotation during the cuts?
Thanks

Hi Guys,

Thanks for your comments about my machining work. I am quite pleased with how things have gone so far :D

I did make the domed cover on a lathe, I should have taken some photographs as I went along, I will do next time. I have done some CAD images to show how it's done though.

I hope this makes it a bit clearer.


Regards,

Sarah

Same here. Don't ask me why but I always put metalwork into the too hard basket and chose woodwork instead. 40 years later I am finding it is simply a matter of applying oneself, not that I am suggesting skill/craftsmanship doesn't play a significant part.

Hi Sarah,

As you can see I know nothing about using a metal lathe. I wasn't aware you couldn't "freehand" metal with acceptable accuracy the way you might with wood. I have never used a wooden lathe either, btw.
