gluing Domino's

[ajcoholic]

Applying glue to the Domino mortises is always a bit of a pain with a regular glue bottle.  Recently I had added a Lamello LK-5 glue pot to my shop, and today I had the chance to try the 8mm dowel tip when gluing a pile of 8x50 Dominos.  With the dowel tip you can quickly apply glue to the entire wall of the mortise, by squeezing the trigger while moving the head back and forth a few times while pulling it up out of the hole.







I was putting together 4 bar stool/chair seats.  I cut the components out on my CNC router (and also the mortises in the arms and seat) and use the Domino machine to do the ends of the slats.

With the Lamello system, since the tips are threaded on - and I have a small machine shop within my woodworking business, I have the idea to make up some custom heads to do the more popular sizes of Domino I use (8 and 10mm) in one shot.  Im going to machine the tip to fit into the mortise with 0.5mm clearance, and a series of holes around the tip.  Inserting it into the mortise, squeezing the trigger and with drawing the tip should give a fast, uniform coating of glue to the entire interior of the mortise.

Ill post back my results.  But this should very much speed up the gluing process.

To apply glue to the 28 mortices on each seat, took less than a minute (no kidding).  No mess and much more even glue application than my old way with a bottle.

Thats some serious gluing!!!

Two questions:

1. How is the pot pressurized?  Air compressor or pump?

2. How long can you expect  a gallon of TBIII to be fresh in the pot with less than daily use?

Expensive, but could be pretty helpful if using a LOT of dominos.

Cheers,

cool system.  for the trades or even for diy with regular large projects.
looks like a bicycle pump connection but perhaps you can adapt it for other air fittings.
you're not dumping the glue in the pot.  it stays in its own bottle and the pressure just squeezes the glue container for constant flow.  so it would last as long as any other bottle of glue, as long as you cap it tight afterward.
my question to the persons that have used it would be:  how easy is it to clean the hose of glue afterward?  would you just run some hot water through it?  the fittings look like they would clean very easily using the dunk baskets shown.

Back 10 years ago when I was assembling cabinet we had a guy who took a old pressure bot and did the same thing. Was way faster and cleaner than a bottle but for some reason I can't remember why we didn't keep it going once he left the company.

Hi Andrew

I love the look of those stools that you are making. My father made some similar but smaller stools, one for each of my children, so they could join us at the dining table when they were smaller. They were nowhere near as good as yours. Do you have any drawings that you are prepared to share please?

Four weeks ago we had just two (2 year old) grandsons, we now have 4 (latest arrived yesterday) and the final one of this "clutch" is due in about 3 weeks. When they come to visit, when they are old enough, I would like them to sit in something that approaches the quality of your design.

Many thanks - oh the gluing is very nifty.

LOL! [big grin]  You'll only need ONE chair, because there's no way on earth you'll get FIVE toddlers to sit for more than 10-seconds! [eek]

Good luck with that! [popcorn]

I go through a gallon of glue pretty quickly so it wont be an issue.  I usually buy my adhesive in 20 litre/5 gallon pails but with this system it is easier to get gallons and drop one into the pot VS pouring it into the liner.

Air pressurizing is done via the Schrader valve (standard like on a car tire) to a max pressure of around 70 PSI/4.5 Bar.  You can leave the glue in, pressurized and ready to use.  The tips are cleaned by placing on a special adapter that goes on the sink facet in my shop, and you just twist it on and run some water through them.

As far as the chair goes - sure, if you want the "drawings" I can send them in the form of a generic .DXF file for the outline of the seat, and the Domino locations as well as the sections that make up the arm (6 pcs).  I drew it up in Vectric's Aspire CAD/CAM, which is what I use to run my router.  If you have that, then you can also cut the 3D saddle shape in the seat.  Otherwise youd have to do it by hand.

The seat is 21" wide and 18" deep at the extremes.  Just shoot me an email if you want the drawings at ajcoholic@icloud.com

The seat is 1 3/4" thick, and the arm sections 1 1/4" thick.  The slats are angled at 10 degrees and are 8 1/2" high in the vertical plane.  An 8x50 Domino is set into the center of each slat and of course into the seat and underside of the arm assembly.

Hi Andrew

Many thanks - I have sent an email.

I have Vectric's V-Carve Pro and am putting myself through the tutorials as and when I have time. What do you think of Aspire?

Pretty slick setup...like a pressure pot for spray painting. The different glue applicators really lay down a nice even layer of adhesive.

Curious as to how often you have to clean the delivery/supply line? That's the one thing I hated about spray painting with a pressure pot.

Aspire is very powerful for quickly creating 3D objects from 2 dimensional drawings.  For instance, a shaped chair seat I can create the file from scratch in a few minutes.  You can draw profiles and extrude them into 3D shapes quickly.  It is still difficult to learn and get very good at (I am still learning after 3+ years) but it is easy enough to get started, especially if you follow along with the training tutorials.  Think of it like a souped up V Carve pro.

As far as I am aware, the glue will not set up in the hose any more than it will in a bottle.  As long as the glue is completely within the hose up to the nozzle, there is no air other than the compressed air in the tank which pushes the glue out. 

Regardless, if need be the hose is easily detached and you can run water though it.

I spray with two, 2.8 gallon pressure pots (using post catalyzed lacquers, solvent based) and yes, you need to flush the lines each and every time they are used or you will be in trouble.  And I regularly replace my fluid hose.  But if you want everything to work well, you need to do the maintenance.

I have had the LK3 system for only about 6 months and I have never cleaned anything but the tips. I clean them the same way Andrew does. I can easily go 4-6 weeks without using the system, I just make sure to not let the pot completely de-pressurize, eliminating any chance of air entering the system. This may not be necessary but I was told by the supplier to do this.
