No, I was referring to the 40/40, which 80/20 Inc. (the company) sells. I was looking at it on their website last night. If that's interchangeable, it makes the Wemacro mount much more attractive.

This might work, these items look similar. They don't show anything that looks like the heavy extruded right angle braces though.

Thanks for the information.

I was on the site last night and looked at the various extrusions. The Wemacro post appears to be solid rather than the type with the hollow sections which you referenced. Would you get the solid or the lightweight type?

It's different and has hollow sections, but the one I mentioned should work.

This brace might work, but nowhere as sturdy as the brace on the WeMacro Stand which is much larger and has the M8 holes 40mm from the face, so the holes in the stand base won't line up with this brace.....you'll need to use the WeMacro braces here where the 40mm bar attaches to the base.

Here's even a simpler way to convert the Wemacro Vertical Stand to Horizontal use, and allow easy switching from V to H and back.

The 40mm square bar is tapped with a 5/16-18 tap on the end, no need to drill as the center hole is proper size for 5/16-18 thread. A 60mm ARCA clamp is securely attached to the bar end with a 5/16-18 3/4" bolt.

A 100~160mm ARCA plate sides in the ARCA clamp and another (40mm) ARCA clamp slides onto the top of the plate. This clamp holds the subject fixture as shown.

Very simple, small, inexpensive and somewhat sturdy horizontal stand is easily adapted from the Wemacro Vertical Stand without any drilling nor machining (I don't count tapping a already proper size hole machining).

Best,

Wemacro now has this horizontal mode as an option on their affordable Vertical Stand.

In my modification of the vertical stand, I added height by installing a long Arca rail rather than lengthening the vertical post. I considered the longer post as well, but the long rail gave enough extra distance for my purposes. The stand has since gone onto another forum member who hopefully will post his experiences with it...

Ray,

Agree a longer post/bar is desirable, that's why I've ordered a 600mm 40X40 bar from Misumi USA. It was only $13.44.

I have been planing for some time now on upgrading my ThorLabs based 95mm horizontal system to include a verticle stage. A couple weeks ago I finalized the design and the parts arrived Monday. I got a 95mm 600mm long bar, this is a massive extrusion, much heavier (and more $) than the standard extrusions. So my expectations are for a really stable Vertical and Horizontal ThorLabs based platform, something I can compare other platforms with and also mainly to use for some of my upcoming high precision chip images.

Best,

Yeah, I noticed that too. Mayhaps I have to contact them directly and ask for certain parts I need, but that'll happen later.

Ray,

Just got home from work and had a package from Misumi waiting. It had a 700mm long 40mm by 40mm bar with a bunch of other stuff, this fits and works nicely with the Wemacro Vertical Stand in either the Vertical or Horizontal mode. I just need to drill a few 1/4-20 holes for the ARCA clamp mount.

The bar is from Misumi HFSB8-4040-X, where X is the length in millimeters. Works fine, the only issue is that the 40 by 40 bar used by Wemacro has a smaller 8mm slot for the T nuts, while the Misumi is 10mm. This causes the T Nuts with the kit to be a little loose, but you can order standard M8 T nuts from Misumi with the longer bar that have the proper flange width (10mm) for their rails, they are only $0.64 each. Their shipping was quite reasonably also.

So folks can get a longer bar if they wish and not have to pay a fortune in shipping costs from overseas (if they have access to Misumi) for the longer bar.

Hope this helps,

Best

I have purchased similar long bars from eBay fairly cheaply as well. There is a seller ("8020inc" I believe) which has a very wide variety of these extruded bars and accessories, for reasonable cost.

Ray,

Yes 80/20 is another source (see my much earlier post). I initially looked to them for the 40mm square bar but decided on Misumi because they were lower cost and have a heavier bar. The Misumi bar I referenced is designed for the M8 T-Nut with a 10mm nut flange, not the 8mm flange.

The Misumi bar should be even more rigid than the Wemacro supplied bar which is quite heavy & good, but because of the extra length wanted to go with the most rigid approach.

Misumi is the extrusion OEM, while 80/20 is just a distributer.

Here's a picture showing the 40mm square cross sections, the Misumi is on the bottom, the Wemacro supplied bar on the top. Note the Wemacro bar is already a heavier more rigid bar than most, but the Misumi is even better.

Best,
