Cutting Fiberglas: How?
Hi,
I noticed that during idling, my engine vibrates enough to constantly hit the water pump on the fiberglass engine foundation. The last two or three big jumps the diesel does when stopped bang the water pump into the fiberglass really hard. So about about half an inch of the engine foundation has to go. What is the best tool to cut really solid fiberglass, and how do I do this? Any advice is appreciated. Thanks a lot, Chris |

How to get at it sounds like a bigger concern. Terry K |

How to get at it sounds like a bigger concern. Terry K I assume you have checked the engine mounts and that there is not a problem. Any cutting tool will do fiberglass. Depending on access I would tend to use a hacksaw. If using power tools try to run a shop vac near the cut to remove as much dust as possible. Wear a mask and glasses. After cutting out the chunk you will need to reglass the cutout since you are probably exposing the ends of the glass fibers. |

Whatever you use, fibreglass will dull the blake really fast. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

I would look at the engine mountings first....but.... Depends on access. You could use a diamond wheel (may clog) or an abrasive blade on a grinder. To prevent clogging, one way is to wax the wheel. I bought a huge block of wax from the local abrasives supply place just foe the purpose. Quite cheap too. You can use candles etc. The idea is that the wax melts, and frees up the stuff to fly away, I am told. Makes sense. If it's a hands only job, then get the hacksaw blade with the carbide grit edge. I find that normal hacksaw blades disappear pretty fast with glass. You can also get grit blades for jigsaws. Make sure the blade does not pull back back into the glass any stage of its stroke, or you risk bending/breaking the blade. Hacksaw and jigsaw will generate a lot less dust. As everybody else said, suck out diust as fast as possible. Wear a mask at least. Probably get a disposable suit and do dispose of it. Are you sensitive to Glass dust? You will pay if so. Some ideas are to cover yourself with lanolin cream etc, then _wash_ it off afterward. Use sticky tape to pull the foibres out etc etc Whatever, do not scrub at glass itch.

Whatever you can make work. Sawzall, jigsaw (carbid grit blades preferred),
Dremel, or 4" grinder might do the job. My favorites are twist drills, hole saws and the Fein Multi-Master. "Chris" wrote in message oups.com...

Before you do any cutting of fiberglass check for the cause.
I do not know what type of boat you have and how old is your engine. First you I would investigate more and try to minimize the vibration. The vibration could be caused by all kind of things, engine tuning, mounts, head casket, valves adjustment, air lock etc. If it does vibrates excessively while turning the propeller your shaft alignment may be the cause.

Any of the tools mentioned will work, but I'd try to find out what
caused the problem--unless you're sure this is a design flaw. you may weaken the engine stringers, or if you may have bad engine mounts as mentioned above, which may also be affecting your alignment. At any rate, the one thing I wanted to add is, if you are using a power tool, esp. if you are grinding, wear a tyvec-type overalls. You may sweat a bit, but it sure beats the glass-itch. If you get glass itch, alternate very hot and very cold water in the shower. It won't get rid of it, but the scalding sensation will make you forget about it for a spell. good luck. mickey |
