Building a Sea Chest

[mbmcdermott18]

Well I decided to put a couple coats of polyeurethane to try and seal it up. We will see how it goes. Ringleader over on classic mako seems to have good success just waxing the mdf.

I am interested in removing these parts. How much force is usually required to separate the mold from the part?

After thinking about it I believe my plan of attack will be to drill a hole in the bottom of the mold through the mdf that will allow the air to get into the mold which will have holes drilled in it to allow the air to get in between the outside of the mold and the part.

Then I am going to thread a quick connect into the hole and hook up an air hose into it. Starting at 75 psi I will work the wedge around the flange and see how it goes. If she doesn't pop at 75 I will increase @ 25 psi increments.

If it becomes obvious that the part won't pop I will just unscrew the sheet of mdf from the mold and take it apart from the inside.

Thanks to everyone who has offered their opinions and advice.

Hope everyone has a Merry Christmas

Mike
