Drywall screws to hold strip planking
Has anyone ever used drywall screws (the black ones for screwing
plasterboard - I think you call it sheetrock in the US- onto metal studs and plastering over) for holding the strips in the right alignment, instead of wooden dowels and/or plywood cleats, or is it a really dumb idea? I mean just for those annoying bits where the new strip won't quite line up over the one in place. The screws don't rust as far as I know and as the whole lot is encapsulated in epoxy afterwards I doubt if they ever would. I've used them for fixing things into wood for years and never noticed any detrimental effect, so I doubt that they would cause an damage to the wood, assuming a pilot hole was drilled first. It's just that they are so cheap and are so easy and quick to screw in. Another Pete |

I used 10 pounds of drywall screws on my cedar strips but made sure to
remove them all. Took 3 days to unscrew them all and another day sweeping the hull with a metal detector to make sure I got them all. Given time they WILL rust. Even under epoxy. peter wrote: Has anyone ever used drywall screws (the black ones for screwing plasterboard - I think you call it sheetrock in the US- onto metal studs and plastering over) for holding the strips in the right alignment, instead of wooden dowels and/or plywood cleats, or is it a really dumb idea?

Drywall screws are real handy around the house ... but ... I would not use
them around the boat ... they do "rust" ... and quickly. peter wrote in message ...

Have probably used at least 100 lbs of deck screws (coarse thread). Built the male mold, and endless numbers of jigs, templates, etc. All of these items would be classed as temporary construction. Even used them to build the bulkheads which consisted of two sheets of 1/2", 4 ply, CDX plywood glued and screwed together with deck screws and then glassed over on each side with 2 layers of 24 oz double bias glass and epoxy. Those deck screws are buried inside all that glass and resin. It was easier to grind them flush than to unscrew them and then plug the holes. They may rust, but I doubt it, and if they do, it's NBD, since they are strictly now little more than core material. For your application, I'd probably remove them where possible.

Isn't it just as easy to use a staple gun and long staples, driven in over
small pieces of heavy plastic to make location and removal easy later? "Wayne.B" wrote in message ...

Depends on the size of the project. Staples are OK for a canoe or
dinghy but my strips were 1.125" thick. Staples would not have worked. auerbach wrote: Isn't it just as easy to use a staple gun and long staples, driven in over small pieces of heavy plastic to make location and removal easy later?

The long answer is still "NO". I've used the staple trick you describe /w/ a pneumatic staple gun, several times, just not here. -- Lew S/A: Challenge, The Bullet Proof Boat, (Under Construction in the Southland) Visit: http://home.earthlink.net/~lewhodgett for Pictures |

The galvanizing is not hot-dip but electroplated, so it's of no practical
added value in a marine environment.
