Received the Domino set today. Had a bunch of edge glue-ups to do. We decided that we wanted to have 5 tenons that would start and end approximately 2" from the ends. We wanted to mark the first tenon and then set the cross stop so that the last tenon would end up about 2" from the end. We finally came up with a formula that we think will work no matter what size tenon, length of board or how many tenons we want installed.
My question:
Is there a formula for determining what to set the cross stop to? I tried to find one but couldn't. I'd like to see if we came close or are way off.
Here's what we came up with:
1 - Mark where the first tenon goes
2 - Determine how many mm from the center of the first tenon to the center of where you want the last tenon
3 - Determine how many total tenons you want then minus 1
4 - Divide that by 2 then multiply by the tenon width
5 - Subtract from the total mm from step 2
6 - Divide that by (the total tenons minus 1)
Example:
2 - 26" converted to 660mm
3 - we wanted 5 total tenons so 5-1=4
4 - (5mm tenon is 19mm) so 4/2=2 then 2x19=38
5 - 660-38=622
6 - 662/4=155.5
We set the cross stop to 156mm and ended up 1/16th of an inch off which was probably due to rounding.
So what do you think? Sound right?
BTW, everything was dead on (or at least close enough) right out of the systainer. Used the exact width setting on all the holes and everything lined up.
Always thought Festool was way too expensive until I finally used them for the first time 2 months ago. Now I've got a bunch of green in the shop and a whole lot less green in the bank. Maybe that's why their tools are green.
