I was watching a exhibit on TV amongst around of my friends, where these guys were literally taking badly rusted cars - they were literally junk pots, in addition to turning them into beautiful "vintage" automobiles that would acquire for several hundred dollars. We were chatting well-nigh a like plan on MTV I used to lookout called "Pimp my ride" where cars represent for the junkyard were modified, cut, converted in addition to painted into beautiful machines.
The guys I was hanging out amongst hap to live engineers in addition to nosotros ended upwards discussing the pro in addition to cons of sand blasting rust off cars. I learnt that's non a really goodness sentiment every bit it tin create to a greater extent than damage. Anyway, sandblasting is quite pop in addition to that was what the guys inwards the exhibit were doing. They removed the rust, patched the holes in addition to scratches, painted them to what I sentiment was a actually high standard. However, my engineer friend told me that the exclusively agency to confirm the smoothness of the surface is yesteryear using a 'surface roughness tester' too known every bit a profilometer. Yes, yous larn novel things everyday.
Apparently you tin quantify the roughness of a surface yesteryear measurement the surface's profile. Most of these are big machines inwards the labs simply I too constitute out that at that topographic point are fifty-fifty manus held portable versions. For example, boom cleaned surfaces tin live tested for the peak-to-valley overstep using a Portable Surface Roughness Tester Profilometer (yes, that's the official advert of these machines). I did non acquire much of the technical stuff, simply that's how the experts testify the smoothness (or roughness) of metalworking or fifty-fifty a pigment job.
So if yous bring a workshop in addition to desire to known every bit a professional person today, your store flooring has to bring i of these gadgets.
