I am thinking about building a tongue box for my atv trailer out of some OSB scraps
my only experience with advantech was garbage. I have built many custom homes and the worst subfloor weathering I ever saw was done with advantech. I would not recommend it for anything! But for a trailer box I would recommend 3/8 CDx or scrapped packing crate ply (1/4-5/16 even). pmf will make a solid part with the added skin strength and the small size will make it a strong unit in the first place. I know people like to overbuild but I see no need; remember the strength of the whole unit is greater than the sum of its parts!MtnDon wrote:Advatech is great stuff for house sub floors. Thinnest is 19/32... most common is 3/4 or thicker. Sort of more than is needed for a box, IMO
having worked with osb a lot (scraps from my house builds) I would say it is perfectly doable. Like others have noted it does have water issues when left to soak it up, and certain glues are watery enough to set it off. It does glue well though, but I have only seen clamped gluing with it; not open faced surface treatment like this scenario. A decent exterior primer (zinsser bullseye) applied on it then canvas applied and primer again on top with a final coat of exterior should hold fine from my experience with the materials and others with pmf in general. As for using scrap osb see John heisz' osb stool...martymcfly wrote:I am thinking about building a tongue box for my atv trailer out of some OSB scraps that are left from putting a new roof on my buddies moms house. I am thinking about trying PMF over OSB. Will the TB2 stick to OSB? Is OSB smooth enough to PMF?
