Great machine, I whish I could think of a use for one because they can normally be picked up pretty cheap.(though making one operate with no experience could be "tricky")

Surely someone who can find a use for not one, but two colposcopes should have no trouble finding a use for an automatic lathe?

The comment about inexperienced operation probably applies to both devices!

Thanks for the info.
These people were very advanced for the time.
Its just a wonderful thing to view mechanical equipment like this, in operation.

For those interested enough. The Bolex factory movie is worth watching again.

lol. Well I guess I could find a use for it.... its finding the space for it thats the problem. The Zeiss is sitting right next to me and the other one is in the spare room, so that saves some room in the shed. She may just think a lathe inside is going over some line or other

Stuart

And I've wondered how you've justified the purchase of not one but two colposcopes.

Hi BT,
That's easy...... the first one cost me $70ish, so I couldn't let the ziess go for less than that. Though its really Rays fault because if I wasn't going halfway there to pick up some wax to try his machinable wax I might not have bought it(at least thats what I told her).

She is very good to me.

So, I can buy the Zeiss from you for 70 bucks! Hold on, I'll go and get my wallet.

No, but it does let you know how much you'll have to bid on the next one that comes along I must say I'm amazed how often I do use it.
