My ideal solution

Just a little update on my small contract. Not just a small contract but small bits as well. These were delivered from the company today.



There are a few more of the handwheels (60+). But the O-rings are miniscule, and not many spares, so I will have to make sure everywhere is kept clean and tidy.

So I have big machines to make tiny bits. Thank goodness I have just had new glasses.

And the shop still isn't ready. So it looks like a bit of give and take on that score.

I think your hand is way to big. That's why the parts look so small.  :D

They are tiny. This is were a Sherline lathe and mill would come in handy. Ah, I keep forgetting you don't have the room for more than a few machines. <grinning, running and ducking as Bog's throws a wrench at me>  :whip:  :hammer:

Darren:
Blimey, do you have to machine these, guess so, would love to see how you hold them in the lathe.... :dremel:

Bernd,

I have friends all over the world, any more comments like that just might get you a visit from people making offers you can't refuse. :whip:  :wack: ::) ::)


Darren,

Any large machine can be made to make very small bits. Most machine limitations are in the mind of the owner.

This is how you do it.


Make holding fixtures, and use VERY sharp tooling.
This was using the four jaw to get the offset crank pin, 1mm diameter. The dimple in the end is the layout centre pop mark.




This is the outcome, this was turned from a solid bar of silver steel (drill rod).




Then you can make engines this small.



And they do run

Never let large machine sizes put you off anything.
