Ok, just tried running the compressor for half an hour and it did not heat at all. Unscrewed the outlet quick connector and screwed a connector where the compressor sucks air.Then taped the inlet . 30 min was ok. Just was going to report here and it turned off. Waited 5 min tuned it on and it run again. It was almost cold to the touch but obviously something heated. But before i rip it apart and search for a termistor or something , i would like to see if it will work for the fixture or not.

Yeah, i read all the threads here and at the zone. However my conclusion is that i have better have fixture for each job or for the universal table, to have a mat for each job. That covers all unused holes and produces enough friction at the borders and may be inside the job too if needed. Some plain cheap mat will be perfect. Later will go on shopping.
