Re: Tube clamp (46C) - Wemacro

Here's a short video on how to model a tube clamp. There is one small mistake in the video: I dimensioned the length of the bottom flat instead of its distance from the center point.

Thorlabs has downloadable models of their tube clamps.

Re: Tube clamp (46C) - Wemacro

I'll be happy to show you how to model one. I don't have all of the specifications for the WeMacro version. It would be best if you requested those directly from WeMacro.

Re: Features for a motorized stage (focus stacking)

It's reasonable, but you should first define your tolerances for each of those fields. Hi elf, Can you explain, why should I first define my tolerances for each of those fields for the StackShot, before that someone mention the values for those fields for the Stackshot? Regards, jac If you don't kn...

Re: Phase contrast annulus, 3D printing

I would have a hard time 3d printing those threads accurately with my FDM printer. An SLA printer would be a better choice. There are several available now for around $200US.

Re: Would you recommend a tripod or monopod for macro in the field?

Actually, a device like that would be rather simple to make. Just mount a Stackshot on a pistol grip :-k

Somewhere in the archives is a post by LordV showing how he uses a pole or walking stick to stabilize the camera. He also has a Flickr account showing it.

Re: Forum upgrade completed

The new format is fine with just one tiny niggling little issue. Firefox doesn't show an icon on the tab. I assume you're talking about the tab in the browser tab bar. As far as I know, nothing at photomacrography.net or photomacrography1.net has ever displayed a site-specific tab icon. If you have...

If the virus can only survive for 3 hours on cardboard and 72 hours on plastic, why would you not reuse a mask after 72 hours?

You might consider an Olympus which does in camera focus stacking. I don't know if Canon has this feature.

p.s. Renting a camera and testing various lens would be beneficial.
