Sizes of Dominoes?

[jonny round boy]

I'm currently designing some furniture which I'll be making once we move to the new house (3 weeks tomorrow, can't wait!!!).

I haven't got a domino yet, but it'll probably be the first tool I get once we're in there so I'm designing the furniture to use them.

Can anyone let me know what the widths are of the various sizes? I know the lengths, and the thicknesses, but not the width of the domino or the width of the slot (I do know that the medium setting is +6mm, and that the wide setting is +10mm).

Also, I saw this in the 'extended' user's manual:

The distance between the locating pin and the center of the mortise slot is 37mm (1-7/16 inch).

Is that from the centre of the pin to the centre of the mortice, or from the inside edge of the pin to the centre of the mortice?

Thanks in advance!

if ive understood your question the cross section of the dominos are as follows

5mm domino      5x19
6mm                6x20
8mm                8x22
10mm              10x24

the cross section information is not avaliable from the UK festool catalogue

this comes from the hafele catalogue (its a german company and when the germans measure something it tends to be correct)

 

[dirtydeeds]

your correct

the measurement from the inside edges of both pins is 74mm

so the nearside of one pin to the centre of the mortice is 37mm

ps good luck with the move

and are you going to design your furniture with lots of parsons mitres

just to make your very first domino project just that extra bit taxing  :

Cheers, DD.

Go on then, I'll bite....

What is a parson's mitre? Not come across that one before...

 

[dirtydeeds]

its a three way mitre, youd get a three way mitre at the junction of a table corner

specifically the two rails and the leg. all three are mitred then reinforced by 3 tennons

whats difficult about it is that it has to go together absolutly perfect first time because you cant get it apart. if you have 4 to do on a table you increase your chance of one failing

youll find it in the extended domino catalogue, i havent tried it yet. I think the catalog is in the festool USA site and i has appeared on the austrailian ubeaut forum

 

[jonny round boy]

Ah, yes,I saw that. Didn't know it was called that though!

 

[dirtydeeds]

my understanding is it comes from the shape of a priests hat (a mitre) which has 3 vertical creases

hence a parsons mitre

Tezzer perfected this joint using two dominos. Do a search on Tezzer here or on Lignum at UBeaut. Great joint and not that hard using his technique.

While on Dominos, you dont have to use the ones you buy. Making them is easy and you can make any size you want. I recently made a 10 x 50 x 50 for a table pedestal. Use any timber you want.

Regards,

Rob

Gonna have to break out my digital calipers and check my tenon sizes again. If you're correct I'm 1mm off on all the widths on this one page summary

Oh - that Parson's Joint - a Triple Mitered Corner is a more descriptive name - and the Chinese use it a LOT - and with a tenon or two coming out of the top to go into mortises on the underside of the table top.

Complicated joint to do - by hand.  Not nearly as difficult - with the DOMINO
