@clarkwerk Absolutely. Aluminum in the presence of most strong acids reacts to produce hydrogen gas and heat. In large enough quantity you get fire or explosions. (When I was in high school, we used to fill garbage bags with H2 gas by taking a plastic conainer of H2S04 or HCl, dumping in crumbled balls of aluminum foil, and throwing the bag over… Don’t ask what we did with floating bags of explosive gas!) In small quantity, the acids will cause pitting of the surface of the aluminum, which increases the surface area of the pitted part, which then reacts more rapidly… Causes pinholes then crumbling.
We passivate stainless by soaking in strong acid until the iron at the surface is eaten away, leaving a chrome and carbide surface (which is mostly non-reactive to the acids)
We have placed on long term loan a delta chop saw that was given to us by Michelle’s dad. It is new old stock. Practically new because it only saw really light work. Old enough that it didn’t come with a finger guard. Heavy enough that I had to brace the table.
i found very thin scraps of ply on in the Mt Paul industrial area where it is used in shipping. They were happy to have me take it away. There is also a gazebo/deck manufacturer that puts out tons of scrap–in this case non-ply, and they are also happy to have you take it away. Let me know if anyone wants to meet for me to show you these places.
Laser is back up - I bought and installed a new 12’ USB A-B and Kile and I installed it in such a way that it does not get beaten by users. Laser freely, brothers and Sisters.
And thank you to @Pierre who diagnosed the problem in 2.4 secs.
@pierre Not sure if it would suit, but there is an old drafting arm/rail system hanging up in the Design Lab - maybe the hardware would work for this? I cant see using it for its traditional use, and I am tired of packing it around!
@Vaughn it is heavy and bulky. It would need some serious maintenance and tune up. The new printer that is in the office is better but still not 100%. It has a dead spot where it does not fuse the ink on to paper.
If you think an inkjet printer would be useful in the design lab, I suggest we move the one in the office up there. That way we only maintain one printer (which is costly) and also save some valuable space. Alternatively (if you dont think there is enough room in design lab) we could leave the printer in the office and you can send your print jobs over the network. Either way, I think keeping one good printer would be best.
