POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[Shiseiji]

yep, tried a heat gun. It's stuck . When it comes off the glue is left, and some paper. Naptha is the best I can do, but there's lot of scraping, and gouging. And still remnants. I also have some lexan, same deal, if the paper is not removed in a reasonable amount of time and its exposed to sun or other elements, it may not come off. The plexi came from a car guy and he was storing it under his cars.. so oil and sun.
The lexan came from the shop of a deceased guy, and his widow said he died like 20 years ago, and the lexan was stored near the windows.

Thanks, very good to know when looking for "deals."

yep, when looking for clear... it won't be. when just looking for plastic, well, it's a good deal.. sought of.
The price of plastic these days is off the charts. Been quite a few years.

Another sad plastics story> A few years ago, I bought some surplus 2 door storage cabinets (typically 18"x36"x78") from a major industrial manufacturer. I went to pick-up and was asked "Do you want these also?" More of the same type cabinets free, sure. When I was almost done loading the 20' box truck (full to the door) he says "Do you want a sheet of Plexiglas?" I say sure, where is it? It was a sheet of Lexan, 5/16" or 3/8" x about 5' x 10'. No way I can get it in the truck with out unloading 1/2 the cabinets and that's not going to happen. But wait, I have a cordless circular saw with me. Is it OK if I cut it in half? My escort goes to ask a guy operating a fork truck (like he's an expert ). My escort comes back to me and says no, because the swarf would be hazmat (we are outside on an asphalt paved storage yard). I had to leave the Lexan behind. Still hurts when I think about it.

It's always better to ask for forgiveness...!

Tried that.

Plastics place I worked at had a small shallow pan, made out of Sentra, with a lid. We would lay parts in and lay paper towels on top, pour goo gone over everything and cover the pan to prevent evaporation. The next day the old dried up glue and paper was fairly easy to roll off. We used it often enough to keep it full of GG!
Goo Gone is far superior to Goof Off, there is a difference.

I hear you. I had to be respectful. I didn't want to queer my relationship with the surplus coordinator. Remember, He gave me what I paid for PLUS about 2x additional.

In retrospect, I probably could have captured it between the lift gate and the box, even though it would have been a couple feet wider than the truck. I could have driven out of the facility and cut it on a side street. It was unused stock with the protective sheet still in place.

After having the blade welder for about two years, and having the cabinet done for at least 6 months, it's finally installed!!!

I needed the holes where they are because the screws are going into the edge of an opening in plywood subflooring. The edge strength of the plywood is much less than the steel. Believe me, I thought about it long and hard, still constrained by needing a solution that could be reasonably implemented. This has already consumed all the free time I had this week and then some, and even that is taking advantage of not having to travel this week.

If this doesn't work, and it may not, the next thing to try would be making a square steel frame that would sit down in the opening, to which these beams would be welded. But that's a lot of fabrication, and I'm trying to move the needle significantly as soon as possible.

And if that doesn't work, we'll need decorative metal grates custom fabricated, which will be exceedingly expensive.

Installed photos. The square tube supports the center of a wood AC vent in the side aisle of my church, and the 3/4” angles support the sides. The louvers on the vents are no longer depending on thin milled wood for support. We were having problems with foot traffic breaking out the louvers—we repaired the damage but the hope is these will prevent future damage.

Now you can see why I needed the holes so close to the end of the steel. The subfloor openings are variably cut—this one was one of the best. The finished floor supports the vent only by its perimeter, about a quarter inch. These braces bring primary support up from the subfloor.

For irrelevant reasons, I am making a vacuum tight chamber out of about 5.5"OD PVC pipe. To close off the end, I wanted to screw a cap on. That's also PVC, so I got out the Machinery's handbook and refreshed on thread computations. I was able to choose a pitch diameter, 5.243", and compute the internal bore of the pipe and the external diameter of the cap, given a 24 tpi thread. From the handbook, it was easy to figure the actual thread depth and be precise about this, because I have to make several of these pipes and caps that interchange. I also cut a seat for a Viton O-ring, and I have to say I was excessively pleased after making both ends, male and female, that they fit together perfectly, including the O-ring.

Two other "fixes" occur to me. Number one is to teach the congregation to not walk on the grates. How to do that? Place a compressed air orifice pointed straight up (1/8" diameter would be enough) and rigged to blast by 30 pounds on the grate. That would bring some life to the services and the women would learn quickly.
Alternatively, steel grates.
YMMV
