I finally finished all the mods to my OBS. Well I still need a shroud around the fan but no problem.What t I did was modify the wiring so that if the rocker switch is pushed to the right I have both heating elements engaged. If I push it to the center position all heat is off for cold smoking. Pushing it to the left sets the OBS at factory defaults. That is that the slider works. The only difference is that the power indicator is just that that everything has power. Now the neon light to the left if the switch dims when you slider to a low temp. I also added a switch for the fan. Everything is is wired after the HI temp cut off so at about 270 or so everything 0s down

I used bolts to make a frame work to hold the fan motor because I have never had much luck bending metal accurately with out the proper tools. This way I can adjust the nuts to achieve perfect alignment. I think this is the best way to mount the motor and I recommend it highly. It's just to hard to correctly to bend metal with out the right tools.

Only thing left to do is to buy a PID unless someone figures out a way to gold plate their OBS the it starts all over again. This free OBS have very expensive but it has been a fun ride and I am sure I will enjoy to for years to come. THANK YOU FORUM for all the information. With out your help I would not have been able to spend $500 on a free rescued smoker (2 probe PID soon come). I hate you all >:( :) :) :) :) Just kidding
Great job!

Nice job!

Great job. I like the switch for the fan. Is it wired directly to the fan and the fan to a power outlet? Or is it wired to the OBS plug in back of the cabinet? The reason I ask, if you do get a PID, it controls temp by cycling the power to the cabinet on and off which would cause the fan to go on and off.
Excellent work with those mods
Nice job!
nice job
Nice job on the smoker and I like the heat sinc on the back ...... good idea.

Yes it will cycle with the PID. I thought this would be a better way to go since I dont need to blow any heat if its off, but then again what do I know.
Any thoughts?
Hey DS,
After the cost of your free smoker, any $$ left to buy somethin' to put in it? Just wonderin'. ::) ::) ;D
Seriously though, it's all about the challenge and the victory. Well done Gladiator!

Well my fan is wired to run independently from the PID heater output and my results have been good. Will be curious to hear your results with the fan cycling on and off so much. There is a lot of cycling of the element once the PID reaches setpoint. So much that the fan might not make it to full speed. The PID will compensate for that after you run the auto-tune for your setup.
My fans are runnin full speed the whole time
Hot or cold smokin
Just sayin ;D
Detroit, what fan did you use and where did you get it? Thanks!

i run my fan full time, Partly because there is still heat in the element after the pid turns off, not much but some and helps to keep an even box temp , top to bottom and front to back
Funny thing I was just thought of that very thing and was just about to post it. The back will always be hotter weather on or off. I thought it would be best also to keep the box temp even leave it on. I will use the switch to shut if off when I open the door only. Don't want all the smoke blowing in my face every time the door is opened.

For the inside I used a 3 1/2 inch fan. It is rather large but is not "windy". The blades are very close to the back wall so it cant get a good bite on the air. I did have to cut the V tray to make it fit. I also put it just low enough so I can still use the bottom rack

For the motor cooling fan I used

You will need a motor with a long shaft. My inside fan just fit after bending the blades away a bit from the back wall
