I'll guess most everyone has seen one of these vids, but this one has a lot that could be applicable to model railroading.

Ok, some of these are cool and very useful, like the stripped screw, whereas others make no sense. Some of these 'hacks' are in fact questionable as well. I would not recommend sticking metal or anything for that matter in an electrical outlet.

I can smell the chemical reaction through my screen. I hope they are doing this in a well-ventilated area because this stuff burns one's eyes and nostrils like crazy.

A few of these could be applicable to model railroading and for that reason, thanks for sharing.

The spray accelerators use something called "Amines" which are derivatives of Ammonia. Both Baking Soda and Ammonia are alkaline, meaning they are highly reactive to acids.

Based on this, I would assume that Lye would also work, but I wouldn't test it without proper precautions. The fumes from these types of chemical reactions can be dangerous.

Never saw it before. I can see using it for some applications. Pretty cool. As for the electeical outlet, yea it would have been easier to change the end.
I thought the same thing: easier to change the plug. And…aren’t prongs of electrical plugs supposed to be metal to… you know… conduct electricity and provide grounding?

I have repaired cracked shells (and filled some holes) with CA and baking soda, which I learned about in another forum. It essentially turns it into plastic and is paintable. Make sure to mask around it and also to form the baking soda into shape as much as possible before adding the CA, though. Filing it down can be a chore.

I can see use for some of that. I never saw that before.
The T-man might have a need for that too. The way he molds stuff up. (y)

Though with todays prices glue is not that cheap, that guy must buy by the case.

Looks like he is cutting lines of cocaine in the one. lol

Never saw any such thing. Thanks for showing it. There's a few procedures I'll keep in the back of my mind.

I agree with Big Ed...those were som straight "lines" he was cutting there! LOL

Actually, this video (or one like it I saw earlier) solved a minor mystery for me: in several of his excellent series of videos, Luke Towan uses a sprinkle of baking soda on the CA that secures items he glued together, and it always puzzled me why he did so. Now I know . . . :)(y)

Mmm, I think both reactions are chemical in nature (I think the plaster of paris setting up is just rehydrating baked gypsum, if memory serves), so I suspect that might not work. OTOH, one video I saw earlier successfully used cigarette ash as the "filler", so it might do just fine. Worth a try, I guess, especially if you've run out of old baking soda from your fridge! ;)

I just thought I would report on my personal experience after reading this thread and watching the video. This repair procedure works very well.

I was custom painting a train car. After I applied the last clear coat, I dropped it and chipped off a tiny corner. I could not find the broken piece and did this CA trick. It worked great.

Broken shell.

Glued on two pieces of styrene plastic covered with painters tape. Glued on with rubber contact cement so they would remove easy. This kept the baking soda and CA glue in place.

A little light sanding and a new sharp hobby knife to re make the groove and then repainted. I still have to put a new clear coat on to even everything out. But I think it came out ok.
