Hi Dave,

I can't help thinking if you eBayed the rest of the old Tek scopes and other stuff in the background, you would not need the new 'offline' storage area.  Now if only I some practiced some more of what I preach... My mission for week, add one new eBay auction per day.

BTW Are we going to get a guided tour of the new storage area :-)

its always easy to go over someone elses house and ask "why do u have all of this shit?? you should get rid of most of this" but its a completely different story when its YOUR shit.

Lab camera now back up and running, and at 06:54 there is nobody around. How Dave manages to walk around there barefoot I will never know.

Does anyone know if the bench surface Dave uses (laminated pine [or whatever wood type is locally abundant] in approx. those dimensions) is readily available in the United States at a place like Home Depot or Lowe's? Looking online I can't seem to find anything like it... the closest is if I search for a butcher block slab but those seem to be more expensive and don't seem to have the nice depth that Dave's benches have (two or three feet deep just isn't enough to have analog oscilloscope with enough work area in front of it).

Solid core wood doors (without any pre-drilled knob holes) are available at Home Depot and Lowes and make good bench tops.

solid core with door know holes drilled are often available at construction sites for free. plugging a hole or 2 isint hard. ive got a few work benches like this around.

daves says his top is 900mm, which is about 35 1/2", which is less than 3'

Actually the door knob holes make a convenient place to run cords through to the floor.

Don't be ashamed, nothing wrong with role-playing Bevo!

Walking barefoot in a lab is easy with surface mount components. DIP's and TO3's are fun, the trick is to keep your toes low.

When I saw the "infinite bench" illusion plan, I got an idea. Make the mat slightly too long put it up against the wall. This should give a bigger span of useful angles for creating this illusion "perfectly". Of course, assuming good lighting conditions so there are no shadows.
Whoa! How the hell did Dave know that Bob is my uncle? Amazing!

They were installing the new fibre link in the building, so the net was down overnight.
I should be able to upgrade to an even faster plan now.

It's carpet, so rather comfortable until you bang your toe or step on something. The good outweighs the bad.

I just use plain 22mm or 19mm shutterply, or go hunt up an old kitchen counter top. You can use doors ( they are under $20 new for hollow core ones) and they work well. I made a few worktops using melamine counter tops with a bull nose on one side, and as they are 50mm thick they can be quite sturdy. They are hard to cut as my skil saw only goes 48mm deep, but a 2 pass cut is fine in most cases before assembly, and leaves a smooth edge as well.

Only 3/4 inch but should be ok. both 4 ft by 8 ft, so I can make two 8 feet long by 2 feet deep:

$23.98

$32.25

Melamine is crap. I would never build anything with it.

MDF is ok for some things. It can work for a benchtop if there is good structural support beneath it. It would not work well in the design Dave used in his video.  It needs to be sealed with a good polyurethane or equivalent.

I did an OIL rub into my MDF bench tops as shown in this eevblog thread and it works fine.  Makes the MDF much stronger once it cures, and makes it a little smoother and nicer feeling as well. Of course we all use esd rubber mat on our benches anyway. :)

The bench top was then oiled. I just use any new unwanted engine oil I have around place – in this case, Castrol GTX. The oil is applied with a brush, left for 15 minutes to sink in, then any surplus is wiped off with a cloth. The resulting surface is dry to the touch, doesn’t show oil stains(!), and can be easily touched-up should it be scratched.

Ikea have good countertops.  I have two birch tops in my work area.  They are not as deep as Dave's, but that was because I don't have the space.  I think Ikea does sell two widths.

OMG...that is funny.

Just for the record if of of "you younger guys" is reading this... DO NOT use motor oil.  Use this or something similar that you will find in the paint/stain section of your hardware store.  You will not find this type of oil at the auto parts store.

Reminds me I must re oil my table, I use furniture oil to do this on the unvarnished cherry wood. Gives a matt finish which has the added bonus of being insect proof. A good thing to have here in the borer belt. A coat every 6 months and it has a nice deep matt finish.
