thanks Rick, the housing is 2 years old and has been in water many times. drilling small holes at the end of the cracks is not really an option for me. but i can take the fittings out and apply the adhesive if this might release the stress and help solve the problem. what do you think ?

Thanks a lot But I guess the epoxy is not water thin so it won't penetrate the crack area. I think I'll try the super glue first. What about the stress crack ? Are they going to stop?

any suggestions ?

Hi i am reposting this question in the polymer section with some updates. i have a clear polycarbonate camera housing ( the one you put a professional camera in it and take it deep underwater. its rated to 60m depth ). i found 3 tiny surface cracks each of 2-3 mm long around one of the control...

Thanks, i don't know much about bonding material or chemicals, so i still have some questions to ask. is using cyanoacrylate ( super glue ) better than using Methylene Chloride ? is it going to penetrate the crack and weld it permanently without turning it to white color or cause more stress to...

Hi i have a bit of unusual question. i have a clear polycarbonate camera housing ( the one you put a professional camera in it and take it deep underwater ). i found 3 tiny surface cracks each of 2-3 mm long around one of the control glands penetrating the housing wall. i know its surface...

what are the machinery required for a MS flat bars production line ?

Hi i am planning to build a steel flat bar production line of capacity 20 Tons/day. the plant uses scrap steel as raw material to produce flat bars of different sizes. what are the suitable machinery and process stages for such line ?

Hi does any one have this book ? i am thinking of buying it but i need to know your review first. Electric Motor Repair by Robert Rosenberg & August Hand http://www.amazon.com/Electric-Motor-Repair-Robert-Rosenberg/dp/0030595843

Does the IEC states that lighting in metal rooms or enclosures should be 24 V not 220 VAC for safety reasons?

fr=0.4 to 0.5 Hz depends on load rotor current = 600 A rotor voltage = 1820 V

thanks if the scope is not available, what can be done ? and if i used the clamp anyway, what would be the error in measuring?

how can I measure rotor current in running slip ring AC motor ? I know that usual clampmeters can not measure low frequency current ?

what is the recommended tests that should be performed on MV slipring motors?

What is the recommended ground resistance for a lightning protection system? i have a system consisting of 3 lightning rods connected to network of 4 earth rods and the earth resistance measured is 1.2 ohm. where is that from the standard?

this temperature is on ONAN. IEC states that ambient temp -25 to +40 while not exceeding +30 on hottest month for air cooled trafo. the trafo suppose to have maximum efficiency around 50% loading but the oil/wdg temp is 60/62 and the maximum is 90/95. What will be the temp in case of 80%...

i have a two secondary’s transformer 132/6.3/6.3 kV 60/55MVA ONAF/ONAN at 50% loading on both secondaries, the top oil temperature is 60 C, winding 62 C, ambient 27 C. is this considered high temperature? IEC standard says that temperature rise is 60K, 65K
