Yeah, you have to logged in to see the file. I got the same message then I logged in. Message shouldbe changed to : you have to be logged in to see this file. Very crappy programming. :-)

Hey there!Seems the link doesnt work for me - error 404 - "That file isn’t here anymore". Best regards, Phil.

I don't think you need to get too worried about this issue. Sure, leaving HCl fumes around steel or machinery is a bad thing but if you take a few sensible precautions you shouldn't have a problem.

This link hopefully will show my tank which has lasted five years so far. It is a jug intended to fit in the door of a refrigerator. It's fairly slim so keeping the amount of etching liquid needed to

It generally took me about 2-4 days to make a PC board. The first day was spent in cleaning the boards and printing the toner transfer paper, and also in transferring the toner to the paper. The

I would suggest the original HCl bottle (or something like it) inside a 5-gallon bucket with a lid, and put a container with some large surface area inside the bucket as well. Any HCl vapour will get

I just put a slab of polystyrene over the container. If it's a bit warped, put a bit of wood on top of that. I've had the same setup and *same* etchant in my lab over 5+ years, topped up with a bit

Diptrace is 500 holes 2 sides free for Non-profit use only. Which is a pretty good start for me to learn it.

I have worked in steel mills and manufacturing and soda companies and had a deep purchasing ethic drilled into me at a very young age. So when I went to OSHPARK and on their ABOUT US web page

Yeah on the cap seals. I think I have a pretty good idea as I have a large yard (2.6 acres). I will put the muriatc acid and/or the etchant mix in a 5 gallon plastic bucket with a lid. I will did a

Yikes! So my 5 gallon bucket with a lid on it won't be the answer. Drat!? What kind of plastic bin do you use outside? I have a dog so I need to be safe there too. Buy like you say, the chems are

Main problem with some enclosures is that the caps or seals are attacked by the HCL. Rubbermaid cereal containers (inexpensive, but while the bodies withstand the HCL, the seals don't).

At $5.00/sq inch you had a 12 sq inch board, so roughly 4 x 3 inches. Yep, exactly how it works. The Chinese board houses do the same kind of combine and send off. Difference is in the volume. what

Dave, I did just that. Plastic container liquid tight. Inside a 6/7 gallon pool bucket. Still rusted. I now keep the chems outside in a plastic bin. no more inside shop where metal resides. On

Yes, on my 3D printer there is a "disable steppers" switch in the control panel to avoid damage when leveling the bed and manually moving it. I think I will leave my 9x29 mill manual only.

Good info Sam. I have a large steel building workshop and would hate to see the panels rusting because of a stupid mistake. I guess if I stored my etchant in a plastic bottle like the muriatic acid

In a one gallon glass or plastic bottle like the one the muriatic acid is sold in.
