Hi,

Long time lurker, first time poster. I've got a Mitchcraft bay boat that needs a new floor.

I had a chance to work on the boat this weekend and managed to get the floor out of the boat.

I couldn't find the charger for my circular saw so I bought a new tool.

If you're looking at these but haven't pulled the trigger yet this is a great little tool. There are just a couple of things to talk about. The first thing I'll mention is although the literature says it will cut 3/4" plywood I'll agree yes it will cut 3/4" ply as long as your cut is a short cut. Cutting 1/2" ply with with a layer of fiberglass approx 1/8" thick burned out the bushings. My fault. I shouldn't have tried to cut the floor out in one day. I worked it to hard. I advise getting the extended warranty. I did and I got a new one. The blades don't have teeth rather they have a rough carbide edge and at 20,000 rpm they gum up epoxy fast. I went though two blades at $20 each. The last thing I'll mention is the depth adjustment is a basic cam operation. The cam lock can't handle the vibration the saw sets up while operating. I noticed dust on the garage floor when I pulled the floor out.

Apparently the depth cam lever vibrated loose and I plunged right though the hull. Any thought as what I should do to fix this is most appreciated. There are actually two cuts both are clean and approx. 1/16" wide and 6" long. My first though is place a piece of tape on the outside and pour epoxy in the cuts and back with fiberglass.

Take care,

Ed L.

hi, welcome to iboats....

sorry that the saw didnt work out.

slices thru the hull happen all the time.....

i would not use epoxy, i would just use thickened poly resin to repair it....then glass the inside and out.

do a search on here....there are tons of threads about slicing your hull

Thanks for the welcome.

I'm a tin boat guy and this is my first fiberglass boat. May I ask what weight fiberglass should I use and why poly resin rather than epoxy?

Re: A little progress on the a floor replacement...and a question..

Your boat is made from Poly, and the Poly is coated with Gelcoat. Gelcoat sticks to Poly but not to Epoxy. Thus you should use Poly. You can use Epoxy but then you would have to paint instead of gelcoating and epoxy has no UV protection and must be coated with something. The weight of the cloth to use depends on what you are doing. With poly you always use Chopped strand mat CSM first and then follow with either Woven Roving or Biaxial Cloth. Again the weight of the cloth depends on the application.
