I'm using the Behlen (sp?) version at about 254 gram weight and it gels up real quick...like 15-20 seconds. I need to use some heat to extend the working time and a tiny bit more water. It works like a charm, though.

JJ, Here's what mario had said a couple of months ago about the 260g, found it back in my files, you had replied to it saying he could probably do it in his sleep , remember? now it seems, that my 269g is more likely 160g which is more gel time than needed, grab a newspaper and read the whole classified adds before glueing, you'll have enuff time!

The first hide glue I used was the LV stuff. They said it was 260 gram then, too. I then purchased a barrel(you know I -am- serious, right?) of 192 gram, high clarity from M&H, which should last half my career.... I also tried their pearl glue; stank to no end, was weaker than flour mixed with milk(LMI white???!?) and even tasted bad <bg>

The LV granular stuff was a lower gram than the 192 M&H, I am certain. They must just buy a barrel of whatever is cheapest, and break it down into one pound bags and sell it. Never mind their "tech" sheet, and never mind what they say it is. I'd guess it is more likely a 160 gram glue.

It was still plenty strong, and had a slightly longer open time than the 192. It was fine. In fact, it was easier to work with than the 192...

Minutes is wrong. You have seconds <bg> 30 seconds is about right, but stop and stare at a clock for 30 seconds, and you'll see that it is a long time. I can get anything clamped in that time frame..... And if you miss, and don't get it clamped, pull it apart right then and there, wipe off the gelled glue, and start over. No big deal, it is very forgiving...

Thanks for the clarification, Serge. I'm not planning on changing from the 192 gram but was interested in the higher gram stuff and how others were doing tops and backs with an even shorter open time.

JJ, since i seem to have 160g instead of 260g, i'm now in your camp and would like to know more about the stronger one too. If anyone knows where to get the stronger stuff and how to work with it, pleas share your input!

Thanks

Higher gram numbers don't really mean stronger bonds. The gram strength is simply a unit of a known size object being pushed through a know thickness sample of gelled glue. Very similar to how they test burst strength on paper.

Read up on the stuff....

Mario, If i understand you well, it is just a testing unit, meaning that we probably just have to play with the desired thicknesss or viscosity to obtain full stength?
