Thread: New Spray Booth for The Shed

Hi. Can you clarify what you'll be spraying in this - i mean what product you'll be using ?

Arron

Could be an interesting work in progress to follow.

Regarding the type of spray painting will be a mix of automotive acrylic , epoxy resins, nitrocellulose, enamel. Now each of these require various types of respirators or air supplied respirators, they each require different levels of safety. The other precautions to be taken is regarding use and storage of the relevant solvents used when using a specific type of finish. The filters for the spray booth and the respirator filter have to match the type of finish being used. When these items are matched correctly they are stable and safe products to use.
The main purpose for building the spray booth is that it will allow me to paint my wife's car which if I had to pay a crash repairer to paint my wife's car it would cost me at least $5000.00 to get a decent job done. This is partly due to the fact that today crash repairer's use 2 pack paint in conjunction with a heated spray booth. Now obviously I won't be using 2 pack paints as they are isocyanate based , this means that the safety precautions that have to be taken cannot be done in your shed at home.
Hence forth the reason why I will be using acrylic based paint for painting my wife's car; the nitrocellulose finish is used for the finishing coats of acoustic and electric guitars.
A good percentage of the skills and safety precautions to be rigidly follow I learnt as a spray booth operator in the automotive components industry.
Getting back to the progress I've just started the building of the 6 remaining rings that makeup the bell mouth housing. When they have been made I'll post the next installment of the spray booth.

Ok thanks. I'll be pulling up a chair for this one. Perhaps you could clarify how much space you are using. Are you converting the entire shed ? What size would it be if you wantwd the minimum practical just to do small furniture items?
Cheers

Just a quick note for the moderators, my apologies regarding some of the images that I posted in the initial thread. I didn't think that I had infringed on copy right laws.

Just pulled up a chair, looking forward to more updates and pics D

Quick update, finally glued all of the bell mouth housing sections together just have to wait for the glue to dry.

In order to install the filter & bell mouth housing I've had to do some re-arranging.

In the right-hand side of the picture behind the curtains was the storage rack for steel, well that has been relocated along with other stuff. So once again time to build another shelf unit. Many thanks to Brad as he had some offcuts of melamine particle board which worked out to be just enough for this shelving unit.

Now you can see the shelving unit was made to fit around the air-con unit. Yes that is a air-con unit there, I was very fortunate several months ago when one of my guitar customer's was renovating their kitchen and in the renovating the air-con was replaced with a ducted system and he gave me the air-con unit. This shelving unit is used for storing timber for turning and the whetstone sharpener.
For the next installment will be the shaping of the bell mouth housing and the making of the temporary frames which will be covered in heavy duty plastic which will any over spray inside the booth area to be extracted to the outside of the shed.
Cheers till next time.

Hi Arron, my shed is 4.8m(16ft) wide by 9.1m(30ft) long and 2.4m(8ft) ceiling height. The spray booth will consist of a modular frame construction with each section lined with clear heavy duty plastic, which will allow to come through.
The area for the spray booth will be 3.6m(12ft) wide by 6.1m(20ft) long by 2.4m(8ft) high. The filters, bell mouth housing, fan and motor will be fixed to the sliding door and supported by wheels to take the load so that there is no extra weight being taken by the sliding door.
The sliding door will have a hole to match the fan to allow fumes, dust etc to be vented to the outside of the shed. On the external side of that door there will be a flap that hinges so that a 90 degree elbow chute can be attached to allow fumes, dust etc are directed to the ground.
The modular sections will consist of 2 walls and 1 ceiling covered with clear heavy duty plastic; each section will be 1m(3ft3in) in length. So this means that there will be 6 sections that are bolted together.
So obviously prior to erecting this spray booth all storage units and work benches are to be compacted in thew opposite end of the shed.

Due to the modular construction method it means that I will be able to make the spray booth as long as the project deems. Other uses of the extraction system will be for fume extraction with the paint filters removed whilst oxy-lpg, arc, mig and tig welding. When I am wood turning it will act as a dust extraction unit with the appropriate filters installed .
So as you can see Arron it will be more than just a spray booth because of the adaptability in size due to the size of the item being sprayed and the different types of filters that can be used.
Cheers Alby

All clear. Thanks for the response.

look forward to following your build.

I missed what you posted to start, I thought copyright still let you post copies of stuff so long as it iwas only a portion but I dont really know - maybe that is just an urban myth

Hi folks time to catch up with progress, along the way there was a microwave shelf had to be finished; so here it is. Shelf 2.jpg Shelf 5.jpg

Now back to the spray booth, with making the bell mouth housing I needed to level the sections for the bell mouth. Henceforth a makeshift router sled made to get the job done; next it will be mounting them onto the lathe for the final shape and of course that will require a outboard tool rest for that job and that will be in the next post.

Well there we have it for the time being, hopefully I'll have an update in the next couple of weeks. Cheers Alby

I'll be watching

Interesting microwave stand. I am guessing it had to match the existing kitchen.

Hi Christos, yes it did have to match the kitchen.

Once the splash back has been installed and the microwave shelf put in the corner I'll post some more images of the kitchen completed.
