Saw this on New Yankee Workshop--?

I was watching Norm this morning on NYW making an antique maple wash basin table. He was gluing up some pieces for the top and lower shelf using biscuits. He applied glue only to the biscuit grooves and not along the entire edge as I would do. Norm then proceeded to clamp the pieces together and I did not see any glue squeeze out along the joint. It would seem that the joint would not be as strong as it would be if glue had been applied the entire length of the pieces. Have I been over-gluing? Or was some TV editing been over used? A new procedure? I need an opinion from the experts.

Dwight

I suspect that it was over zealous editing.

I THOUGHT he rolled glue on the edge, as he applied glue to the slots?

I did knot see it, but even Norm could have made a mistake. It makes no sense to me knot to glue the whole joint.

The norm for Norm as I recall is for him to roll on the glue then go back with his fancy pre-measure bottle and do the biscuit slots.

I did not see the same program you saw today... he was making some trays on our PBS channel.

Dwight- it is very hard to over-glue a joint. Any joint can be "under-clamped" thus not squeezing out the excess glue giving a poor joint that is only as strong a a piece of dry, hardened, glue.

After obtaining reasonably fresh glue, there are three major parts of making a good glue joint:
1) A tight fitting smooth (preferably knife cut) pair of mating faces,
2) Adequate glue to penetrate the cells and lumens of the wood,
3) Adequate clamping pressure for an appropriate time for the glue to penetrate and firm up.

You can have excessive squeeze-out from using excessive glue, but if that can be removed, there is no problem. On the other hand, to little glue or glue starvation, this yields a joint that lacks both in physical and molecular joint connection - a poor joint. A rule of thumb is strive for 20% of surface squeeze-out

If Norm didn't put glue on the edges of the joint - only on the biscuits - he had a very poor joint/connection.

I watched Norm briefly today as he was making a doughbox out of reclaimed pine. He used a roller to apply glue to the edges and had a bottle that deposited glue right into the biscuit slots.

Frankly, I thought that some of his table saw working methods were a little scary. He doesn't use a guard, and sometimes it looked as if his hands were rather close to the blade. He squared off one end of a board on a sled, and then turned it around and used the narrow edge against the fence to cut off and square the other end. With the slightest bind, the blade could be caught on the unguarded blade and be thrown off into space - or into your face.

Norm also cut a "dutchman" repair patch using a hand held router and templates. That was OK. However, he then freed the patch friom the wide board by running it edgewise, in a manner similar to resawing on the table saw, with the blade extending about 3" above the table. No feather guard was used, and the blade was trapped in the board. Personally, I would have used the bandsaw - much safer!

I've noticed how Norms confort zone is MUCH smaller than mine.

I'm okay with being a wimp...

My 2 cents, The times I've seen no glue used is on dust skirts to allow for wood expansion of the case, but it is usually stated to do it that way. I watch alot of NYW episodes, and it seems to me that Norm likes glue.

Hi,

I found I have that show on tape and maybe you were distracted for a brief second when they showed the glue being rolled on but it is there. On my tape is at 5:49 into the show...

I like to tape the shows because I'm often nodding off while watching just after lunch and missing stuff. Somehow the sounds of woodworking relax me and I often wake listen to the credits at the end of the show...

The proof is in the pudding--seeing Ed taped the show would strongly suggest I need my eyes checked. Thanks to all for the info. I'll keep gluing like I have been.
