Anyone test strength of TBII Extend vs. regular TBII?

I'm done - no more banging my head on the wall. As I said before - you're clueless, and that's not likely to change.

Have a nice life, John Sellers

thank you for your concern.

Hey Dave, here's a serious answer.

Modern glue should have a strength of somewhere around 2,000 psi, or else it's not working. That's _strong_. Now any attempt to test this needs a test sample of a couple of square inches minimum (or else edge effects are troublesome) and that means big chunks of steel frame, hydraulic rams and a load cell / LVDT to measure things. Like a lot of people hereabouts who also do some metalworking, I've a bearing press that would allow such a thing to be scraped together with a day or two's effort. But without it, using techniques like "Hitting it with a hammer and seeing which breaks first" is a bit like measuring flammability by asking Johnny Knoxville to dip a dwarf in them and light it.

There's also a huge variation in glue strength, owing to surface prep, material properties, technique etc. Unless you can control this (unlikely) or you repeat enough experiments to average them out, then you're more likely to be measuring random effects of knotty timber or poor sanding on one piece than you are measuring real glue differences.

I hope you resolved the color mismatch by re-painting and NOT by swapping out your Powermatic gear! :)

Loved it! However, I fail to see some of the humour in the periodic table. I understand it's a parody, but what I don't get is why real elements like garlic, pasta, and zinfandel are included with the other obviously silly ones.

Would you do a "comparative" test of umbrellas by seeing which one made the best parachute?

[Bay Area Dave]

yes. That would indicate which one could hold up to near hurricane force winds. That would be a legitimate test, LAWRENCE!! Let's get you a job at Underwriters Lab.

My reading comprehension is just fine. Just thought you'd might like to learn how real engineers would test something - they use a valid testing protocol. Your test was not comparative, since no one in their right fricking mind would use a joint like that in any proper woodworking project.

You'd do well to take your own advice, Davy.

You could always go old school and use hide glue.

[Juergen Hannappel]

That is not really slow acting in a useful way: You have to cloamp for a long time but you cannot work it for more than a minute because as soon as it cools down it doest work any more.

[p_j]

You can use different bloom strengths, change the temp of the workshop or add urea and end up with long work times.

[Andy Dingley]

I rather like that. It gives a high initial tack on cooling. Although it's not enugh to avoid the need to clamp, it does help to stop things sliding around when you're putting the clamps on.

I find that a lot of hide glue glue-ups can be assembled on the bench, then a simple strap or rope clamp is enough to hold them overnight. White PVA would need each joint clamped individually.

or liquid hide glue. not QUITE so old school, but still has a long assembly time. couldn't find it at my local HD, but what else is new. I'll check around town. thanks.

Woodcraft and Rockler both carry Titebond liquid hide glue. I have found when glue-shopping at Rockler that it's wise to check the expiration date.

I _think_ I've seen it at Lowe's, but I could have hallucinated that.

Sears used to sell it, too (with their name on it). Not sure if they still do. Check dates there also.

Thanks, Doug. I'm 4 blocks from a Sears. Lowe's is over 30 miles until they get a new one built not far from me.

Late coming but we hope you'll remember it "before" the next bout.
