This comes up as I've been fiddling with my domino 500, 4mm tennons, and half inch ply. I've come to the conclusion that these tennons are really only good for alignment and really don't offer much in terms of strength not that I was expecting much. However, I'm curious as to what depth you could drill for 5mm dowels as I believe more penetration , in the case of a joint for a frame, would actually add some muscle to the joint....for what strength there is in half inch ply...

I suppose in theory you could drill 2 40mm holes and use 2 5mm dowel rods and cut them to just under 80mm giving a glue surface area of 250mm. Not sure what the surface area of a domino is, but the greater the glue are The stronger the joint
oh ya lots of ways to do it, I'm just kinda comparing the usefulness of the DD40 vs the domino 500. For the projects ive used my domino on thus far I have to say I'm disappointed with it. I'm sure it will be more useful to me with thicker materials and different joint applications but over all it's a bit of a let down. I don't like the ergonomics on it, I find the accessories cheaply made and unreliable and I have plastic bits falling off it all the time that i have to search my shop floor for. This tool is meant to be handled very delicately in order to produce accurate results a little bit to delicately for the pace of work I want to do. More than once ive had to plug misaligned mortises and replunge, despite concentrated efforts to ensure everything is lined up. I suppose im still getting used to the machine but what i was expecting to achieve with it is not what I'm getting thus far. Again perhaps its just not being used for the right application yet.

Yeah more is better in gluing area but if you put to many dowels in or domino's in there will be a tipping point when you start to weaken the ply too much, but can't say what the point is exactly. I'm not clever enough to work out the mathematics to that. Properly 32mm is close enough. I do know that a clued joint is structurally stronger than a joint mechanical fixed as it has a larger surface area where a mechanical joint ie with screws has a high pressure point in that place, but they are much hard to get constantly right and the gluing has to be just right or it will fail. Where screws the application is much easier. A lot of people when they glue up a joint will slap the glue on thinking it's going to improve the strength of the joint where in fact it will weaken the joint. What happens is the glue set around the outside but in the middle it never fully sets causing the glue to be weak as glue needs air to set and it can't as there is film of glue preventing the air from setting the middle of the glue use full nonsense
The Domino (DF500) does seem a bit fidgety and the plastic accessories don't seem up to par with the rest of the tool. I added Seneca's Domiplate pretty early on and that made a huge improvement in ease of use. I seem to get way better registration, plus you don't have to use their plastic "base support" (it's horrid) when machining the cap side mortises.
P1cc with Tilting Base, KSS80Ec/370, MT55cc, F160, F110 and AeroFix Guide Rails
That base support is the biggest joke about the tool, that and I find the placement of the dust extraction hose to be a real bother. The more I use it the better I am with it but I was expecting more from such a highly regarded tool. Should have stuck with Ferrari red as opposed to Gremlin green in this case.
abdon: I stand corrected , the angle fence is only attaches with F -Tracks , what confused me was , that the Timberwolf site mentioned it will work with the NFU machine, yes it will work but only I guess when you use the Ftrack , with other tracks Like the KSS L.

glynnco: Did you order from GereedschapPro? I see them as in stock but I'm located in the US and am not sure if they ship here. I sent them an email asking about shipping but it was returned undeliverable...

jonathan: I've purchased a lot of stuff from our neighbours @ GereedschapPro.nl As far as I know they are one of the larger Mafell dealers in the EU. I can recommend them, they usually respond quickly.

lasse: Thanks for the tip! I have own a mafell rail which is 160 cm and one that is 80 cm. Will it work just as well or will I need to buy rail that is 110 cm?
