a Steel Box Section Build with SBR20 & Ballscrews Plus a few questions

[grain_r]

Hey Rob

Thanks very much for that. I will have a look for brick acid. I haven't heard of that before I guess it is for cleaning mortar from bricks so I will have a look at the builders for it ? I saw a video recently that Ron covell uses some acid to do that too. I did look for the weld nuts in a larger size for the CNC feet but I think I will use the acid instead.

Thank you very much.

Vicious stuff, keep it away from your skin.

That's Cat piss for brick acid it's only 5% active our Chip shop Vinagar is stronger than that. . . . . . Good Hydrochrolic brick Acid is 28% now that will make your tongue curl.!!

Oh and fumes from Hydro Acid are just bad if not worse than those from Galv so be careful.!!

Wow It all sounds like an outside job then. and if I ever don't want fingerprints there's the stuff.

Def outside job with mask plus eye protection. The fumes from Acid are just has bad the stuff it's self so be careful.

Oh and You wan't Sulphuric acid to get rid of Finger prints! . . I can let you have some if you like. .

I hope I never upset you, If you offered me a drink i'd certainly think twice i'm trying to work out if you have a workshop or and evil genius lab.

Yes Jazz - I know all this and more (chemistry at Uni), thats why I recommended the Wickes stuff. It will get the zinc off in about 15 to 20 minutes and is not as dangerous as more concentrated hydrochloric or sulphuric acid. I am not so sure about chip shop vinegar, acetic anhydride would do the job, but I certainly wouldn't want to inhale the vapours of that stuff.
I have been told that in Barnsley, the pigeons fly backwards to avoid getting the shit in their eyes. Is this true Dean ?

Happy Holiday.
