Topic tags/keywords: plywood face glue glue up glue time

Hello, I was just wondering if someone could tell me how long I should let 2 pieces of 3/4” Baltic birch ply that are face glued dry before I can run them through the TS and final dimension them? My concerns with not waiting at least overnight are: could cutting have too soon cause them to warp? Can glue that is still possibly tacky ruin my blade? Anyone have input? Thanks!

I think that the directions on the glue bottle will recommend how long to wait before “working” the joint. Usually about 8 hours, I think.
I don’t think that the glue will ruin your blade but you may have to clean it to keep from leaving burn marks on future cuts.

If you are using Titebond it depends how you use it later. If it is a stressed joint you should wait 24 hours. Non-stressed 30 min to 1 hour.

cag0331,

I am risk averse by nature. Therefore, I would wait until the glue is fully cured, based on curing time stated on the glue bottle. This way if something bad happens after making the cuts you do not have to wonder whether the problem could have been avoided had you let the glue cure a little longer.

If it’s PVA glue, then it dries pretty quick… Titebond recommends 30 minutes to an hour for an unstressed glue joint, which is pretty typical for other PVA glues as well. An hour or two should be more than enough. For other glue types, consult the manufacturers recommendations.

Cheers,
Brad
