    all your thermo/hygros are calibrated I pray?

    also see how the fan has to hit the lights? should hit just below on the round part of the bulbs to send the heat front...

    this is one of my reg coolers

    I have two of the ones you posted about in the last post..how do you calibrate those? I also have two indoor outdoor..three reptile ones with probes..one that came with a Dickies incubator...a fake egg thermometer and a spot check. Half of these I can't put in water. I have no clue how to calibrate those or if you even can

    160watts reached 95 degrees. How big are the air vents?

    As for calibration, What really matters is at 99.5 degrees how far off are the temperatures reading. If one is a degree low mark it as a degree low so you take that into account when reading the temperatures.

    You defiantly have not failed at this project. Most of us who have built these incubators have had to fine tune the design before use. Sometimes that means tape and cardboard to see what works and what doesn't (later replaced with proper materials). My record so far is a 8 degree hot spot in the bottom of a incubator on a first test (they say heat rises....lol) so don't feel bad im sure yours couldn't be that bad.

    If you could post your original picture with the temps added ( Microsoft paint ) then we may be able to give better advice once we see where the hot and cold spots are.

    I don't have Microsoft paint..but the hot spots are at the top and colder the the bottom..my vents are 3/4" closed off almost all the way. Only two of my thermometers are the same when checked against my spot check and a medical thermo. I went to the store after work and picked up two repot heat bulbs. I just put them in so I'll check it in a while. It boggles the mind as to what I could be doing wrong here. I do appreciate the help and fingers crossed I can get this thing rolling! This is what I'm using as a thermostat.ive used it on another bator so I know it works [​IMG]

    sounds like the fan is not circulating the air. You said in the original post that the incubator has a 4" false back. I presume that you have a air intake at the bottom and a fan at the top. If you take tissue paper how does it move in the air flow. Does it look like air is being drawn into the intake.

    You may need a small mixer fan (pc fan running slow) to push the air down.

    I just did what you said with the tissue..I put one little strip under each level and one right in front of the bottom intake..all of them are wiggling from the air movement. The bottom one is being sucked in..my fan may be just to big! I think I'm stuck with it tho [​IMG] the fan is 8" from metal to metal so??? It's an in line duct fan

    what if you put a small tin baffle in front of the lightbulbs? to push the air out the sides from the lights and then down into the bator. I dont think its the fan, the cabinet bators have bigger fans than the duct fans I believe, you dont know the ratin on the fan and google compair with a cabinet bator fan? that will tell you for sure
