using 700 size dominos with 500 size 10mm cutter

[chuckbucktail]

Hey all

I'm working on a large storage system and thought I had it all figured out, then things keeeept oooon chaaanging. So when I was doing some test I realized that I was severely compromising the integrity of my existing domino joints by putting another domino though perpendicularly to attach the shelf panels.

I will attach a sketch of the project but here's what I am attempting to do. I will make a 28mm mortise in brackets on either side of shelf panel and a mortise straight through the shelf panel itself. I'll then trim 10x24x80 XL 700 size dominos to 74mm. 28+28+18(baltic birch ply). The brackets will sandwich the shelf panel and with a good glue joint should be pretty strong.

The original idea was to use through bolts but now I own a df500 so I'd like to make it work with no hardware.

Anyone use these larger tenons for the 500? Don't see why there would be an issue but I'm new to the tool so figured I'd ask for some second opinions.

Thanks for any input.

Curiosity question, why not just use these?

Since you’re planning to cut tenons to length anyhow.

Snip.

You'll encounter no issues with using the longer tenons. I did it twice, first time using the longer ones intended for the XL, and the second time making my own.

Local shop is out. Apparently they're having a hard time with lots of Festool stocks.

Thanks Chuck. Good to know there will be no issues.

Considering building 42 of those square assemblies, plus then attaching the shelves, that will be a lot of repetitive domino practice, but not much variation!  Did you pick this design for any particular reason?

It will work fine. I have done it several times. I've done it with shop made and  the Festool sticks.

Ha! Well, are you trying to say its boring?! The design was originally going to be a flat pack, hence the through bolts that I am now replacing with tenons. That combined with a healthy dose of inexperience scaling up like this and a knack for making things difficult this is where I’ve landed. 42 squares are assembled so no backing out now!
I also think it will look cool. The square assemblies are walnut and will be shaped after mortising for a more organic/live edge feel, and the shelves will get a similar treatment after being faced with 1/4” walnut.

Plan is to use th middle “overwidth” setting on the 500 for the plywood so there is some tolerance.

The only thought I have looking at the mock up is being tippy. 14" is not a wide base, I know it has the L-shape which will add some stability but I would want some stretchers near the top so it can be anchored at least on one side or the other to a wall. Not really any diagonal bracing in the design so being tied to a wall will stiffen the whole unit up a lot. I guess if you don't intend for much weight on it you might be ok without, but if I were quoting that for a customer I would refuse to build it without some sort of diagonal bracing or stretchers to tie it to a wall since otherwise I am not sure I would trust it to take much weight over time. Maybe that is part of the plan that you just didn't put into the sketchup. Front to back you get rigidity from the squares but side to side you are relying completely on the joint between the two racks, weight on higher shelves will amplify that leverage with very little in the design to fight it.

Besides that I have used the bigger dominos with the cutter on the 500 without issue.

on an additional note, I do like the look of it and like the idea of the wood choices

Thank you. I believe it will be pretty handsome in the end.

Well, my elegant solution to reduce any side to side movement would be toggle bolts and some brackets to secure to the wall. This will hold vinyl LPs so there will be a considerable amount of weight.

You will be boring for a while!  [smile]

Post pics of the final outcome- you’ve got my interest with your wood choices
