Working with Weld-On 16 ?

[Funky_Fish14]

Please do not use Weldon 16 as a gap-filler. Basically, all weld-on 16 is, is a syrupy version of weldon 3/4. 3 and 4 only have a slight difference in set-times. If you are good with 3/4, its probably better to go with those for the seams. You can pull it off with 16 but as you said, it makes assembly more difficult. I use 16 if the joint is crappy (which is also going to be something not holding a lot of weight). I mean it works for filling minute little gaps, but dont rely on it to fill visible cracks. If you want to strengthen joints from the outside or fill gaps, use weld-on 40.

Cheers,

I spent some time in the shop last night messing with all this. First, I'm now pretty sure that I can't assemble the 5 pieces of the box quickly and accurately enough for weld-on 16.

Also, I took some scrap and bonded it with weld-on 16 and got a feel for how it sets-up. frankly, I found the Weld-on 3 made a better-looking joint (fewer voids in the joint).

Fortunately, I've got a good table saw with a fence and a blade that cuts plastics well so making fairly smooth edges isn't a problem.

I'll post some pictures when I'm done.
