Here are the steps and the costs that I went through to build my studio.

Because of the way I setup the corner desk, I decided to fabricate my own hood. I just took some wood and made a triangle frame. I then laid some metal sheeting I cut to fit. I purhcased 3 sheets from HomeHardware. This part only took one sheet of metal. One sheet was 16"x36" and cost 8.49$. I then cut out the circle for my duct. I secured it to the wood by adding nails approx. every 4 inches.

After this image, I added the fan on the underside of the hole you see. It is mounted attaching it to two of the sides of the frame. My fan has a range of settings allowing me to alter the CFM/temperature if needed. 

Once the fan is added, I took the remaining two sheets and nailed them to the front.

I decided to go with the corner style setup. My shed was a good size, but small enough that I felt a corner setup would maximize my space. I found this desk on kijiji for about 40$. It has a second set of shelves that I am going to cut and use for extra storage, and as extra support for my ventilation hood and ducts.

Because of the wooden desk, I needed to fire proof it. I have purchased High heat enamel, used for barbecues and fireplaces. I was able to find some at Canadian Tire for about 20$. It can handle up to 900°C (which is a little over 1600°F).

My shed is metal, but it's pretty thin. Just to be safe, I also painted the corner wall with the same high heat enamel. 

The triangle frame is held there by four bolts through the wood frame and the shed wall. I drilled holes through the wood frame, and matching holes through the walls of the shed. I have one by each of the "front" corners, and one on either side of the "back" corner. 

For additional support, I have also added two rebar pieces underneath to help carry the weight. I had the rebar left over, so there was no cost associated with that. I drilled holes in the frame to support the top of the rebar. As well as holes in my frame on the floor to ensure stability.

Lastly, I tied rope in the center of the frame and attached it to the roof strut, for extra extra hold, and stability. 

This is the final product of my basic set up. I still need to add electrical and the torch. The desk I got came with additional shelving. I was able to take these and turn them sideways for easy-access storage. The shelves are only about 4" deep, but that's enough for tool small glass storageFew additional things: My floor has two thin rubber mats from Canadian Tire. They were 12$ each. I needed something to smooth out the spaces between my cement blocks. Also I was given an old hairdresser chair. It has wheels and is able to be adjusted height wise which is a plus.
