OT when it rains it pours..literally OT

[Plymouthy Adams]

as a few folks who  participate in the chat knows I have been putting together a sandblasting building..well it is all together, totally under pinned and set up with scavenger exhaust etc.  Well it failed the acid test today..it rained like a double bladdered cow on a flat rock..I had a number of leaks in the roof...seems they are all at the screws..so I will be pulling these and installing new plastic washers and add a tad of caulk at the same time...I should have tdone this before it rained..we had to move the roof in one piece...we also had to lift it over a 6 foot high priacy fence to get it out of the prior owners yard..to say it shifted a bit would be an understatement

Better to find out now, Tim, instead of later. Sorry to hear of the problem but I know you will have it fixed in no time. Looking forward to pics of sandblasted items!

[Plymouthy Adams]

so am I Robert...just a minor setback I hope..if it is not pouring tomorrow..the guys will be here with a co-cart engine for me to look at...get them help me put up my huge stepladders and walkboard so to reach the screws without fear of leaning on the roof panels

Tim.......................check out home depot for a rubber washered screw. I built an out building for my oil tank that heats my shop and it has a fiberglass roof . I used these screw to seal and attach the roof to the studs.

I had a flashback when I saw the pictures of the building because I had one just like it when we lived in Staten Island.   We got good use from ours and I'm sure this one will give good service as well.

I put one of those together brand new from Home Depot at an old house to store all my lawn and garden tools and supplies.  I imagine it wasn't easy to disassemble and move, lord knows that putting mine up by myself took half a day.

Tim,

 

That's a nice looking shed!  I've cobbled-together a few sheds in my short life but usually they consisted of used plywood of whatever dimensions I could scrape together and dirt floors so please don't think I'm being critical of how you've put that one together.  I do have a few questions why you did things a certain way, though, and I'll pose those now:

 

     First, the exhaust system seems backwards to me.  It looks as though you plan to suck the air (and sand and dust) upwards and have fresh air come in the vents at the bottom.  That would work fine for just the dust, I guess, but you'll still need to suck sand off the floor with a separate sucking unit.  Why not put the exhaust fan at the floor level?  Using two inlets from the shed means the moving air will use the inlet with the least resistance and (by-and-large) ignore the other and neither of them will lift sand, so why didn't you put the suction pipe opposite of the doors (which will probably leak some anyway) and down on the floor?

 

     Second, since the snow load in your area is traditionally minimal I would think an opaque plastic roof would be preferable to metal for the light it would let in.  I know that type of roof material isn't free and you already have a perfectly good metal roof that won't leak by the time you read this, but I have a small shed in my backyard with a shingled roof and no lights that cries desperately for a source of light.

 

Again let me say that I'm not being critical of your shed in any way; you have never struck me as the sort of chap who would do something without giving it some good thought first and I'm simply curious as to where my reasoning is in error, if at all.

Randy..I will try to explain my concerns and I think you will see the reason for the way I did the builidng.  FIrst off I do not intend to be inside the building while sandblasting.  I plan to stand on the stoop (not in the pictures yet) and stay away from the dust and other fallout that occurs with blasting.  The position of the exhasut vents inside and at the top is to get rid of the silica dust and provide a positive air flow from outside the building to the inside and along with the blasting air movement in that direction..keep the media again, inside the building and moving away from me.  The lighter weight dust will be sucked from the top and that part is not reuseable if reclaimed thus get it gone and let the heavy particulates fall to the floor where I will recycle it till it is as they say Gone With the Wind.

 

The vents at the bottom are noting move than to provide ventilation and thus protect against mold and mildew from beneath the building.  I underpinned the building for certain  if I did not, armadillas would be burrowing there almost immediately...also keep out pregnant cats out and litters of kitties.  The floor got painted green because Don Coatney embarrassed me into it.. granted he was not here to help with the rolling of the top coat...where is he when there is work to be done????

 

I have a full face respiator..(bearded such As I am).,,complete with combo chemical/HEPA filtration..I have special perscription glass that is used with the respirator.  I have my ear muff for hearing protection and my gloves and sandblasting hood..

 

You about right about the sealed roof as I read this..I need an extra hand with about 8 bolts and then the roof is hopefully sealed....Lighting is not that bad..what I have in there is what I had about the house laying in the way...I also just found about 20 commercial light fixtures yesterday at a recycle business uptown.  I plan to get about 8 of those units.

 

Not shown in the pictures is yet another layer of 3/4 Avantex wood that will be my sacrafical floor when sandblasting....I needed to have the building somewhat dry inside as I plan to store the items needing blasting there till actual time I do the blasting..if all goes well I should be able to do my limited hobby blasting of the parts larger than my 5 foot wide blasting cabinet can hold and be in a protective enviroment and try to keep myself safe at the same time.

Tim,

 

Thanks for a concise and detailed reply.  Not being inside while blasting changes pretty much everything and answers all of my questions; the doors being open negates the lighting issue (especially when the supplemental lights were so cheap), and mildew\animal protection isn't something we need to deal with around here so it didn't cross my mind.

 

I didn't realize under-coatney came in a green flavor, but I guess that's a story I'll have to wait for.  If you painted the stoop the same color and named it after him ("The Don Coatney Memorial Stoop", or some such foolishness) think it might shame him into coming down and bending an elbow when the time comes?

Hotay..the roof is sealed..my items to be blasted soonest is stored within..the stoop I just finished a short bit ago and christned  "St. John's Stoop"

 

I did not get a picture but I had my 12 foot step ladders set up an used them as walkboard support..I used 4,    2  x 6 x 18's two wide and two thick and lay across these to reach all the screws on the ever so light steel roof.  I am finished for the day...

Tim,

 

With muted humility shall the name be accepted.

Are those pavers set in sand? 4 seat mini bike? Have a blast!

[Plymouthy Adams]

recycling Don...framed the 'pavers' in pressure treated deck wood left over from the moving of the building..the pavers are the firebrick from when I removed the chimney from the house when adding the upstairs and yes we recycled some blasting sand with these.....the mini bike is mine for use at swap meet coming up and the four seats bolt onto a Mini-Moke

[Don Coatney]

Do you have a trailer to pull behind the mini bike?

[Plymouthy Adams]

no..but I do have a luggage rack and custom 'cycle' trunk to attach
