I'm installing 1 3/4 t&g osb for a basment floor on 2x4 sleepers. This
is my first subfloor project.

How do I get the tongue of one 4x8 sheet to mesh with the groove in the
adjoining one? Pushing doesn't seem to do it (although I found out
that construction glue is really, really sticky), and hammering just
smashes the hammered side. Kicking it didn't work.

I'm wishing for something like a come-along that would PULL the two
sheets together, but I have no idea if such a thing exists.

I'm doing this myself, so I'm wondering if the normal method is to have
several beefy guys just lean into each sheet to make it snap in. If
so, the damn book neglected to mention that in the "needed tools" list!

Maybe use a hydraulic jack to push, & a 6' 2x4 along the edge?



I will bet that you mean 1-1/4" as I have never heard of
1-3/4". But to get back to your question, lay a 2x4 along the
free edge, then tap the sheet into the groove with a sledge
hammer. Doesn't take much effort.

For future installations, I always use the tongue as a leading
edge and tap the groove onto it. It is easier to install that
way.
