Boatyard Safety -- DIY accidents that happened to you or that you witnessed

Angle grinders are one of my least favorite tools to use. They're right up there with chainsaws for being able to do a lot of damage fast. By the time you can say "oops" it's already likely to need a trip to the hospital.

Routers could do frightening damage since the cutter can spin at 30,000 RPM.

"high-performance woodworking machines ... Routers with variable-speed motors run between 8,000 and 26,000 rpm."

After many years of 'not reading MSDS ' , I was surprised that the use of Hemmpel's Aluextra did effect me. A-fouling in plenty of breeze , about 5 hrs exposure ,body covered but no footware , no mask . Disposable gloves failed ,some fumes .Hands and feet exposed. Result next day - dizziness and loss of balance. After (4) weeks it is clearing but did I learn a lesson !!

On another forum (YBW) some of the "experts" were suggesting MEKP as a liquid suitable for removing Kwik Grip (contact cement). I was aghast and tried to warn them but was kicked off the forum before I could.

MEKP is extremely dangerous.
"MEKP is listed as a highly toxic substance and is categorized into United Nations Hazard class 5.2. [3]. Its colorless nature and minimal odor"

Kiwi Grip is a coating, not something applied with contact cement. Maybe they were talking about Treadmaster or similar?



I sure hope they meant MEK. Otherwise, not at all smart.

I was trying to do a good job on the shower/toilet on the yacht I was building. I had taken note from several forumites who emphasized the need for soundproofing. I had fitted an exhaust fan (130 cu ft/min) which was quite noisy when in use (I thought that was good). I lined the bulkhead with wet area paneling.

When it came to the door I figured there should be no gaps and the door edge should close onto a foam rubber strip for further sound proofing. Finally I made up a fiberglass (divinycell cored) door.

Then I entered the toilet and attempted to fit the door into a fiberglass door frame but (not surprisingly) it was a little too "proud" in a couple of areas. After carefully sanding the door it finally fitted.


Then I tried to get the door out of the frame . Not to worry I'll get a screwdriver and lever it out I thought. But (in semi darkness) I could find absolutely NOTHING that could be used.


Eventually I found a small 1/2" screw which I hand-screwed into the gap between the door and the door frame and after about X5 attempts I was able to remove the door. PHEW!!

KWIK grip

Yeah, the only way I've managed to remove dried contact cement is with a sander.
Usual precautions, of course
