I am having a print through problem on a laminate that only shows itself when it is warmed by the sun. The laminate was post-cured to about 170* and has been taken up to that same temp on a regular basis by the sun but still shows print-through above about 120*.
The epoxy laminate is hand-laid...
Hi
I am trying to get a 'feel' for how much a beam (rectangle tube steel) is weakened by drilling holes in it and have been looking for free software on the web that might show me this with no luck. I do not wish to solve complex problems but just want to get some idea if I drill a beam to run...
I recently had a custom part cast for me by a small company. I am fairly pleased with the result but while polishing it I have noticed a number of small pinholes in the casting that will be detrimental to my planned high quality polished finish. I have tried to sand them out but with no luck...
I am looking to cover a wooden object covered with epoxy with chrome paint. Does anyone have experience with these coatings and can give me advice on the best one to use? The object will be out in the weather and fairly strong winds.

Hi
I hope this is not a stupid question. I am looking to cover a shaped piece of styrofoam, (Dow Cornings 'Foamular'), with epoxy and am wondering if it will crack the epoxy with changes in temp. of about 30degreesF. From about 40F to 70F. Foam is approx. bathtub size and similar shape.
Thanks...

I am trying to find a chassis of certain measurements and characteristics.
Is there a database of general info such as wheelbase dimensions and suspension type or would I have to track down each vaguely promising car and search their details seperately?
Possibly an American car/truck of the...
I am trying to find out what would be an adequate hand lay-up of a car body. A company making replicas told me they use three layers of 2oz mat with vinylester resin. This seemed a little weak to me.
Would you agree this was stiff enough for a non-stressed panel? Or does it depend on the...
Can anyone tell me what would be the acceptable voltage drop per day or week on a battery in a car that wasn't being used? If car is new, has factory radio/alarm/etc.
Is there a standard that companies use on how long their car can sit unused before it fails to start?
I vaguely remember reading that in a cold start situation with 2 available batteries you get more power if you heat one battery using the other then start the engine with the warm one rather than simply connecting them together.
Is this true and what would be the best method of heating?
Thanks...
I am looking for the best way to stiffen I-joists to stop floor vibration. I have to use the minimum depth allowable by code for height reasons but realize the floor might feel too 'soft'.
Does anyone have any experience with this problem?
I am trying to find an anti-fouling product that will work on surface-piercing props (Bronze). Everything we have used so far washes off quickly.
Does anyone have experience with a product called 'Propspeed'? (I've seen the website but didn't see any surface-piercing props there.) Or can...
I recently installed a device on top of an aluminum sailboat mast at the request of the owner. It's about a foot long, made of stainless steel and looks like a wire brush with hundreds of fine wires coming out of it in a spiral pattern.
The manufacturers claim that it dissipates the ions or...
