Domino 500 joining question

[JINRO]

]Hi, quick question on Domino 500 for joining two different thickness woods together.
The thicker wood is 2x4. I am trying to make hole on 2 inch surface.
Domino plate height can be adjusted I can only go so much it allows.
Is there anyway I can increase plate height? Or is there any other way I can approach this task?

*I've included picture for better understanding.

Thanks!

You reference the machine off the outside of the joint. So set it to roughly half of your thinner material then make your plunges.

There is a solution to this, but it takes some "outside the box" thinking".
You need to make an "adapter block" that is cut at 45 degrees and double-stick tape it to the fence of the Domino. This will allow you to register the Domino from the long point of the miter instead of the short point.

I would not use Dominos. I would use a spline. I told the saw blade to 45 degrees, cut a slot through each end, insert a glued spline. I use this technique for boxes. It makes a very strong joint.

It does. That works just fine, there is the issue of seeing the spline, if that is a problem?

I either overlay a very thin strip of the same wood over the top to hide the spline or use a contrasting wood for the spline as an accent feature. I prefer the latter.

I almost tried this but bit seemed to get far away from the wood too, making it shallow hole. I'll try this method and see. Thanks!

I find that the thicker the mitered/beveled shim is, the better the registration it offers against the work (on the face side), and the more accurate the machine is held at 90* to the beveled edge. I made mine out of scrap about 20mm thick.

This is brilliant. I am going to try this too! Thanks!

That is exactly what I was talking about, but didn't have a pic to show it. Thanks ChuckS

guybo posted a similar photo well ahead of me. I just wanted to point out the thickness of the shim being a factor.  [big grin]

 

[Crazyraceguy]

Indeed he did, I must have scrolled to fast and missed it.

Every time this comes up, I think "just use the fence attachment and work off of the long point".  It takes me a while to remember that the Zeta is the one with the fence face plate that has a 45-degree detent for working off of the long point, not the Domino...  [doh]

The other difficulty with dominos on the long edge of the miter are twofold:

1) plunge depth.  For this, I have some custom plastic clips a friend 3d printed for me that clip on one of the domino shafts.  They are of varying thicknesses so I can plunge to shallow depths.  Doing so will keep you from plunging all the way through your material.

2) cut dominos.  Short, custom domino lengths are easy with a miter box and Japanese hand saw.  Great for dominos in thinner stock as well.  You don't get much in the way of long-grain glue strength but the alignment assist more than makes up for it.

I love Chuck's shim... great idea!

[member=68884]fraz[/member] can you provide more details and maybe a photo of those clips? I think I understand, but not certain. Would love the files as well.

 

[ChuckM]

Yes, a photo or two about those clips would be nice.

I have no access to any complimentary CNC service, and use the Traxxas pre-load spacers (TRA 3769) from RCBoyz.com as clips instead of pvc tubes.

A pack of 2 (16 spacers) is about $12 Cdn these days:https://www.bigboyswithcooltoys.ca/products/tra3769-spring-pre-load-spacers-1mm-4-2mm-2-4mm-2-8mm-2

Same idea as r/c shock collars (I'm lifelong r/c racer so I prolly have all kinds of that stuff in. box somewhere).  In r/c you use clips like this for a lot of adjustments such as caster and wheelbase (smaller clips).  Ironically the toy-grade cars use clip on collars like this while the race cars are all threaded shock shafts for fine-tuning ride height.  My buddy CADed some up and 3d printed from ABS filament.  Shafts are 14mm diameter and my go-to thickness stack is 3.63mm, 3.12mm, 4.67mm, 4.15mm, 4.15mm, so roughy 19.67mm for using 5mm dominos in 12mm.  Works killer.  I will say that while other clips may work perfectly... the fit and "snap" of these are amazing.  He is a professional machinist and mold maker for a living so he gets tolerances spot on.
