I got a fairly large blasting reservoir unit that is probably around 20 gals or so. It's ok if I can't blast the whole side of the sub at once, I'll just go at the pace the unit can handle. I've got this really hard slag in places where they formed the hemispheres, from the heat. It's as hard as diamond ! If I hit is with a slag hammer it pops of, but in very small sections. I tried grinding it and all it did was polish ! It'll come off but slowly. I'm going to experiment with the blaster tomorrow. I might try and rig a scuba facemask for back in the battery compartment later.<BR><BR>Brian <BR><BR><BR><BR>--- <A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A> wrote:<BR><BR>From: hank pronk via Personal_Submersibles <<A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A>><BR>To: Personal Submersibles General Discussion <<A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A>><BR>Subject: Re: [PSUBS-MAILIST] Zinc coating<BR>Date: Fri, 1 May 2015 17:38:29 -0700<BR><BR><BR>Brian,<BR>What size compressor did you buy? Sand blasting is a dirty job, but I love it, I find it relaxing. Get yourself a good hood that has an air feed. I did not know that silica sand is dangerous, that is all I use but I wear heavy coveralls and gloves. My system is 80 cfm at 80 psi and that seems plenty. I never reuse my sand because it looses bite and like Alec says, it will plug your tip, but not until you have crawled inside a tight space and got comfortable :-)<BR>Hank--------------------------------------------<BR>On Fri, 5/1/15, Brian Cox via Personal_Submersibles <<A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A>> wrote:<BR><BR> Subject: Re: [PSUBS-MAILIST] Zinc coating<BR> To: "Personal Submersibles General Discussion" <<A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A>><BR> Received: Friday, May 1, 2015, 7:55 PM<BR> <BR> I<BR> guess I should blast my viewports as well.
