Thread: Boiler and Metal Theft. |
23/05/2012 13:49:11 |
Don't think they'll have much chance of retrieving these items,earlier this year £15000 worth of copper cable was taken in Paisley, last year thieves stole a 1 1/2 ton cast iron bell scrap value £5000 from Johnstone/Paisley, gone without a trace and nobody saw it being taken. Scrap dealers must know this stuff is nicked. So its about time they came down really hard on dealers that accept stolen scrap, a few heavy jail sentences and confiscation of property against proceeds of crime this would soon change the dealer’s attitudes to this sort of crime. .

Thread: mercury or quicksilver........Barometer? |
14/04/2012 20:07:11 |
Mercury is very toxic, implement in conditions such as ALS. As boys we played with mercury and it does, if dropped, separates into miniscal droplets, it is also absorbed through the skin and as a vapour it is just as bad, the reason that many dentists are against removing amalgam fillings. Nowadays we have a much better understanding of what effects such things as mercury, asbestos and lead as well as vapours from soldering, welding and burning have on the human body. Most are cumulative and the effects can become suddenly debilitating even leading to death. So proper precautions, eye protection, masks and gloves with plenty of ventilation should be the norm nowadays. Believe me when I say that someone dying from ALS in a very short period of time from being very fit is not very pleasant. |

Thread: Grinding on the side of the wheel |
12/01/2012 22:58:17 |
I have a small book ' Handbook on Tool Room Grinding' printed by Norton Abrasives of America. 1938
Its quite a comphrenensive hand book on grinding, from it
"Side Grinding"
Grinding on the flat sides of straight wheels is often hazardous and should not be allowed on such operations when the sides of the wheel are appreciably worn thereby or when any considerable or sudden pressure is brought to bear against the sides.

I guess the problem with long web address hasn't been resolved, I've changed it so that it doesn't mess up the web page.

Thread: Preventing Rusting in Garage |
21/10/2011 23:26:30 |
If covering with any form of material, cotton sheets, old blankets remember that after a couple of days they will themselves become damp and need airing, I have seen what covering a lathe with blankets can do if left for any length time.
I cover my machines with bubble wrap but only in large sheets drapped loosely over them, some ventilation is necessary and I try and leave the door or window open as often as possiblethrough the day.
Making sure you have a good ventilation system helps. |

just cheap vinegar, cleans rust and scale off after a couple of days soaking, light rub over with steel scouring pad.
This works as well
Once worked in a boatyard engineering shop, did a lot of work on naval boats and ferrys, they bought in a company to blast the hulls, water jets and grit, the hulls were cleaned down to bare metal and then quickly coated as the metal would begin to rust straight away, the water jets would cut through a 4 inch staging plank like butter.
Be a bit drastic in the shed though ![]() |

Thread: My Big mistake with spraying |
21/07/2011 01:00:09 |
worked for a guy once who sprayed cellulose laquers in his workshop with a wood burning stove going, no mask or ventilation. He is still with us, well into his seventies! Never seemed to affect him. |
