Thought I'd give a quick update and thoughts on my Paulk workbench build, which is now complete.
Really enjoyed the process, and the almost architectural aesthetic gives it great presence and is very pleasing. It's hugely useable, easy to set up, and the leg assembly is very forgiving on slightly uneven floor surfaces such as my suspended wooden board floor.
I don't have a router or the 2 large holesaws the plans call for, so I decided to do all the big cuts freehand with a jigsaw. Consequently they're not as uniform, but this is just a cosmetic issue and really only noticeable up very close.
The dog holes on top are well worth the effort. I did mine freehand with a combination of auger and forstner bits. Took a while and quite a few battery charges.
12mm ply is perfectly adequate.
I didn't add the router table, and will retro fit the table saw fixture (without the additional mitre tracks). However, rather than use just the bare poles suggested by Ron, I will be building a more universal plywood box 'cradle' that will sit on the poles. My table saw will then sit inside the cradle, making it easy to accommodate any future change to my table saw.
In summary, it's a very intelligent design and well worth the effort. $10 for the plans is a bargain, and Ron has even produced a series of videos of an actual build that make the whole process very do-able.
