Overall, the video was very helpful.
I did have to keep in mind the numerous errors in dimensions. Fortunately, most of them had some post edit corrections in the form of text to point out those errors. The parts that I kept saying to myself, "What?! What won't work, or just why?", was when Rob and Luther would mutter amongst themselves, or give knowing glances, but not explain to the audience why they decides not to do something or to change something. An explanation for the audience would have been nice in order to prevent us from perhaps making the same mistake. For instance, when Rob started to build the trestles around the form he made, he rotated the form several times and told Luther, "We'll, sometimes things just go wrong." What was the issue?
Anyway, I will proceed with building my workbench as soon as the weather gets a little nicer. I did submit just one or two questions I thought were important, one in response to an email from Rob, the other through you "Contact Us" email. Didn't get a reply to either.

I purchased the video materials after watching the YouTube content about the Cosman Workbench, as I had some unanswered questions. Faced with two options—either figuring things out myself or spending hours searching the internet—I decided to invest in Rob’s video.

It turned out to be an excellent decision for several reasons:

Comprehensive Instructions – The workbench construction process is explained in detail, with no steps skipped. This significantly reduces the chances of making mistakes.
Additional Woodworking Techniques – Beyond the step-by-step guide, Rob and Luther share many valuable woodworking techniques that can be applied to other projects. Given Rob’s expertise, these tips are of exceptional quality.
A Rare Look at Rob Using Power Tools – The video provides a unique opportunity to see Rob Cosman working with power tools, which is not something you often come across.
The final workbench turned out exactly as promised—sturdy, versatile, and aesthetically pleasing. And the bench vise? Definitely worth the price.

Suggested Improvements:
Metric Measurements – Providing a cutting list and drawings with metric dimensions would be very helpful. As someone based in the Netherlands, I had to manually convert everything to metric.
Adjustable Height – Since changing the table height only requires adjusting a few cuts, it might be useful to introduce this flexibility into the cutting list, making the project even more adaptable.
Overall, this video was well worth the investment, and I highly recommend it to anyone considering building the Cosman Workbench.

I’d looked at a few designs and this was so well thought through to make it easy for a relative novice to build a workbench that was good enough to do very good work on.

After watching a lot of videos and shopping for benches, I made the decision to order these plans and build the Cosman bench myself.
The bench is solid and well designed. The video and drawings kept me out of the weeds during the project. It is rewarding to have done it and, as a newer woodworker, it did not take long.
I also purchased the aluminum sofas and casters, which really make this so much more enjoyable.
10 out of 10, I would recommend it to anyone.

I feel as tho Rob's style changed a lot, and there has been a couple mods after the initial video. I think he should do an extra part, revealing after the fact things, tips and tricks, or just showing off new mods. (wheels, hydro mdf, storage, etc...) Thank you
