there is 24x36x .250 aluminum plate priced not TOO bad, and if you found something else the seller had that you wanted for $25 to make it a $100 order the shipping is free. No affiliation I just searched Ebay for aluminum plate.
Have a great day today unless you have made other plans :-).

The rails worked great. Thanks.

A couple of weeks ago, I stopped at Bed, Bath & Beyond to look at cutting boards, since some people recommend them as a base for macrophotography.

They had a nice thick and heavy one for a about $40.

I cut my extra t-rail in half and mounted the pieces as on the previous mount.

The cutting board works great. It's heavy enough to be stable (after applying rubber feet to the bottom). I don't even need to clamp it to the table top.

Is that maybe UHMWPE ?? We use UHMWPE for a lot of stuff at work....they just refer to it as UHMW.....I love mass market found materials at retail that are way cheaper than buying in other ways :-).

Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), or high-performance polyethylene (HPPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu.[1] The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.[2]
UHMWPE is odorless, tasteless, and nontoxic.[3] It embodies all the characteristics of high-density polyethylene (HDPE) with the added traits of being resistant to concentrated acids and alkalis, as well as numerous organic solvents.[4] It is highly resistant to corrosive chemicals except oxidising acids; has extremely low moisture absorption and a very low coefficient of friction; is self-lubricating (see boundary lubrication); and is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel. Its coefficient of friction is significantly lower than that of nylon and acetal and is comparable to that of polytetrafluoroethylene (PTFE, Teflon), but UHMWPE has better abrasion resistance than PTFE.[5][6]

Nope, it appears to be good old fashioned wood. It certainly drills like wood.

I got the last of my gear for using a microscope objective on my camera today. I did a live view test with a 4x finite objective on the end of two sets of M42 extension tubes. For a subject I used a 148gr. .38 Special wadcutter round stood on its nose. The rim looked like the edge on view of a manhole cover.

You might find this interesting.
The stop can be re-purposed easily as a light mount.

That's more useful information. Thanks.

Here's a shot with the objective, the swiveling part of a cuff link:

So far, I've been very pleased with the cutting board as a base.

Still, living across the street from I-90, there are some vibration issues.

So, I got some thick sorbothane feet to replace the small rubber feet that it sits on now.

I'm back the serious macro mount project.

A guy on photomacrograpy.net has convinced me to go with an 18"x24"x5/8" mild steel plate as the base.

I'm going to mount 80/20 type aluminum extrusion(s) to the plate and the automated rail to the extrusion(s), so I'm only going to need to drill and tap a few holes in the plate.

I'm looking for a Cleveland area place that'll source the single plate for a reasonable price.

I've emailed the hardware store and am awaiting an answer, but am looking for other options, especially in the Cleveland area.

Thanks.

Most steel suppliers can provide steel plate sawed to size, so called blanchard ground plate will be really nice for what you want.

3/4" might be way more plentiful than 5/8"

This will give you an idea on $$..they have 24" x 24" listed.

Hot rolled is cheaper but not nearly as nice, it has mill scale on it.

The hot rolled you can order a custom cut size which would be your 18x24, and get 5/8" thick and it would be like 239 plus shipping.

Also a smaller local machine shop would be worth stopping in and asking, if they have steel delivered once a week or more it will save you paying a minimum charge at a steel supplier.

Do you want me to get you a quote on a pc. of 5/8'' A-36 plate cut 18.00" x 24.00"? I work at a fabrication shop in Twinsburg.

I'd a appreciate it. Do they also do drilling and tapping? I'm going to need at least one hole at one end. I might need more, but the forum where I get my technical advice appears to be down for the night, so I won't be able to ask any more questions until tomorrow at the earliest.

Thanks for your help.
