Several things illegal under Oregon State law with this post due to the dangerous conditions created, please do not duplicate this information.
see 210.21, 404.3, 404.14.

edited 404.21 to the correct requirement of 404.14

After reviewing the cited sections, I have to agree, you are correct. Thank you.

210.21, to be in compliance I would need to add the proper supplementary protection at my ''power strip'', or simply exchange the 30 amp panel breaker for a 20 amp panel breaker since all of the receptacles are rated for 20 amps, Table 210.21(B)(3). The total connected load is well within the Table 210.21(B)(2) ratings.

404.3 seems to be in compliance.

404.14 (B)(1) and (B) (2) seem to apply and are in compliance.

404.14 (E) may not be in compliance, at least using the connected hardware since it's rated for tungsten lighting loads, however a Nichrome load is electrically nearly identical, having a lower inrush.

404.14 (F) does not seem to apply because the switch is downstream of the receptacle.

However, I would submit that all of the hardware downstream of the receptacle is in fact a portable heating appliance and thus Section 404 does not apply at all. If this were installed as a permanent installation then it would absolutely be out of compliance.

I'll edit my original post to reflect this.

Today i had to do some emergency car repairs in the big garage. I was hopping to get number plates for the little niva so i'll have time to fix my 605 at a slower pace but stuff happends. Anyway i had to fix the front suspension, in the summer i got airborne with it and completely destroyed my electric front shock absorbers both anti roll bar links and one bull joint, as always i had spares in my garage so i got on with it, only suprase was the bump stops they got destroyed beyond recognition, and rust had formed in the top head bearings, i bought new bearing, bump stops and dust boots, this took me almost an entire day, well i also clean the inside, did an oil change, and swapped to winter tires. Spring compressors, ball joints, this kind of work is hard on the human body, thankfully i don't do it every day. Before you ask, here is a video how the electric suspension works, keep in mind this is a car from 1992, Ah hope you practice your french. :

The piece on the right started out looking like the piece on the left. 20 hrs of 2 amp electrolysis and a skim with the face mill and I'm off to the races. My original prewar compound was run into the work by prior owners enough to undermine support from the tool post, costing me a teensy bit of precious rigidity. I hope the extra metal up front makes a difference!

Nothing terrifically exciting, just one more indicator holder aka trav-a-dial. This one is for the x-axis on the MF horizontal miller.

I could have used a magnetic base and skipped a bunch of steps, but as much as I like magnets they can be a tad annoying sometimes. And besides, there was a perfect T-slot on the front of the table just begging to be used.

The basic form was derived from a piece of aluminum angle in the scrap box, and a bit of whittling and filing fleshed out the details. I made a double T-nut not because it needs to be so heavy duty but so that the indicator stays lined up when changing positions. Not that that’s so hard to, but it was an easy workaround so I did it. Shapers are great for making T-nuts. There was already a 1/4-20 tapped hole conveniently located on the front edge of the cross slide (for what I don’t know) so I took advantage of that for locating a small tab for the device to bear against.

All in all in works pretty good and does what I want it to. No batteries, no cables, no wires, and it slides off with two turns of the wrist if I need the space for something else.

Thanks for looking!

Great idea, analog all the way!
You know, if you set studs in the T-nut and made some oversize knurled nuts to fit the studs, it'd be tool-free (I never seem to have the right hex wrench hand).

Thanks Mike -

It's a 4-post lift; these GMC motorhomes have only two lift points and a 2-post lift doesn't extend far enough to reach both. Something in the motorhome design about the longitudinal frame members being in compression and trying to pick them up just anywhere on the frame is a no-no.

It has to be raised only at the front crossmember and the rear pivot point between the bogie axles. My original thought was to get a two post hoist but those more knowledgeable about GMCs convinced me to get a 4-post. I also got a 'rolling jack' accessory to be able to lift one end or the other for suspension and tire and wheel work. In for a penny, in for a pound.

Spent my day rassling with heavy steel parts. It's about half assembled. Time for a soak in the hot tub. Aaaah

I've watched those old GMC's forever, almost bought one several years ago & I've regretted walking away ever since, they're still ahead of the time.
The 4 post lift will be useful forever, if setting it up doesn't kill you! I've got an old 2 post & sometimes it just "feels" a little unstable, I've wished it had 2 more legs more than a few times.

Well, so far, so good. I'm awaiting the delivery of a 3/4" masonry bit to drill holes for the anchor bolts but anchoring is not really necessary to use the lift as gravity has a pretty good hold on the whole megillah.

Photo shows the lift and GMC, eventually there will be a 30' x 40' building over the top but what's there is good enough for the present.

Would you like to tell us how you got airborne?

Oh my goodness, it's the EM50 Urban Assault Vehicle!

BMW X5 going way too fast causes a pile up accident right in front of me, i turned left to avoid it and ended up crossing the medium and up the embankment in the opposite lane which was empty and under construction, braking on grass wasn't effective i had enough speed to get all 4 wheels in the air but not enough to lend it level, i ended up nose first in a pail of gravel and scraped up blacktop. That soften the impact but still it was a hard lending, if my airbags wore enabled i'm sure they would have blown, the driver of the bmw got 6 mounts jail and was out in one, the insurance did not pay anything but at the end of the day i was fine and my car drove away from the accident. Oh yeah, my front bumper resembles a background from a horror movie i broke a fog lamp and i'm pretty sure i have couple of broken motor mounts, which are next to address just as i finish the exam i have tomorrow.

Durn! Glad you were able to survive the experience ... and drive away!
