Dowels pulling out11/16
We are using pre-glued dowels and having boxes pull apart at install. The dowels are staying in from the insertion machine, but the manual joint is letting loose. We've tried varying the glue and the glue type. Any suggestions?
When I used them getting the correct amount of water in the hole was an issue. Seems like they need some kind of atomizer that would spray sideways applying the moisture to the side of the hole. Liquid water just ran out the hole. I finally gave up and just used a schneeberger glue applicator with glue.
Not familiar with schneeburger but we use a pizzi applicator on the face side and it puts the glue out from the side of the injector which coats the entire hole. If the entire hole is not coated we experienced the same problem as the glue just sits at the bottom of the hole and doesn't really make contact with the side surfaces.
We fight that as well. A couple pocket screws help when you can hide them, or we do as the other's have said. Yellow glue were it needs to count
Coating the hole with glue is a must. Try another brand of dowels. We use excel dowels 8mm fluted and have for years without problems. We use water in the edges and franklin doweling glue for the face side. Even driving the dowels in the edge with just water we usually find the dowels break before we can get them out and that is immediately after driving them in.
Matt had same problem keep using water
Just use your Tenso connectors! Haha!
I was mesmerized by the Lamello glue guy. The music really puts you in the mood to watch a highly skilled craftsman at work.
I have been glueing with a brush, finger, roller or stick my entire career. I want a Lamello gluer, but I know I will never be able to afford it.
We had similar issues. We found the depth of the hole in the face and how much the dowel protrudes from the side are critical. We have a 2mm air gap at the bottom. We the use Jolly Colla glue guns to put a specific amount of glue. Our goal is to have enough glue in the hole that it pushes its way up. We determined what that amount was and created a glue gage which is hundreds of specific depth 8mm holes in MDF. To set the glue gun you fill the hole. It enables consistency. We do not attempt to shoot glue in the sides of the holes.
