Hi all, I'm going to be making a server rack out of plywood by stacking CNC cut pieces together to form the profile. I like the aesthetic of this and it'll match my speakers. The process of the stacking takes quite a while, for the rack it'll take about a couple of hours and so I'm looking for advice on long term curing wood glues. I need to move the pieces around for the full two hours. When I did my speakers I stacked 12 sheets using Titebond III and unfortunately had to deal with some misalignment as the first sheets stuck together before I could finish the stack. I don't think PVA will last long enough. Anyone know what I should use/where to look? Thanks
Titebond III is the best there for wood. they do a a liquid version called hide glue which has around about an hour or so work time https://www.axminster.co.uk/titebond-liquid-hide-glue-ax22595 i dont think there is any alternatives perhaps maybe from 2-part epoxys with a long cure time but the mess/clean and some cases fumes means its not worth it going down that road. but from what you are saying you will be breaking/moving the contact points? if so the bond will be weak. might i ask what exactly are you building that would need some movement before fully curing?
Second Titebond III as very good wood glue. Had a good look and I think you are unlikely to find any glue that will give 2 hours to keep adjusting.
Titebond III a go-go. If anyone says otherwise, they're simply incorrect. Over-size and trim if you can't guarantee you'll get it right on first-set
Titebond is my go to for all wood related projects, as has been suggested finding a wood glue that has a 2hr+ working time isn't going to be easy, can you not pin the various layers together with thin gauge nails/pins or screws? the hole will be covered by the next layer leaving only the final one that needs to be aligned perfectly before clamping it? I made a table top (similar to the laminated ply tables you can buy from untothislast) a while ago using that method and it worked out fine, much easier than dealing with a massive glue-up.
Can you add holes for dowels at the CNC stage? It'll make alignment a breeze (perhaps, I don't have a complete mental picture of what you're doing). As an aside, I always use PVA. It smells of childhood and gets a plenty good bite. Also, dirt cheap.
If you're CNC-ing each piece could you include two holes accurately positioned on each layer for alignment/keying? That way to could have a vertical through piece/pin either for accurate alignment, either permanently or just for construction.
