I'm building a workbench for hobby electronics. I have have my basic blue prints for the bench.
I want to install outlets(3-4) along the back of the bench, embedded into the workbench. I want to have two plugs from the workbench to my home outlets.
What cabling would I need? Can I cut up a power cable and tie it into the outlet box, and string the wire from one outlet to the other?
I like power strips similar to this for work areas. They are nice because they have an on/off switch, which if mounted in an easy to reach location could save life and limb.
Using a power strip like this should not be a problem, as long as you don't run too many tools at once. And it should conform to most codes, as it would be classified as an extension cord (I think).
I suggest doing exactly what TechShop does. They hang conduit in the ceiling, and above each expected workspace area is a 120/240V twist-lock power connector. From that, a cord drops down supplying power to the workbench. (In their case a 4-outlet box dangle on strain reliefs giving two 120V circuits in an MWBC configuration.) I have to believe that arrangement is code legal, since the facility is tip-top and generally a class act, and it leases space from Ford.
You say "warehouse type space" which means commercial rules may apply, mandating conduit not Romex. Be careful here, conduits can only hold 9 current-carrying conductors (hots or neutrals, except neutrals don't count in MWBCs) before you must derate amp capacity or use larger wire. That's because a stack of tightly packed wires at rating make a fair bit of heat. If I expect to be near limit, I'll hang 2 conduits instead of 1.

My suggestion is that you consider installing a ready made plug strip across the back of the work bench. These can be purchased from many suppliers and come with an already attached heavy duty power cord that you can attach to the home outlet. Here is an example of what I am suggesting:
Let me also make another suggestion (coming from an experienced electronics person myself) that you should consider the possibility to install the plug strip up under the upper shelf of your bench instead of at the rear as you have indicated. It is much better for real usage to be able to plug things in without having to reach behind all the junk that accumulates on a work bench.
Here is a picture showing the ideal location for the plug strip. Notice how it is not hidden behind all the equipment on the bench.
