DF700 for tables: legs and stretchers
« on: July 31, 2022, 11:37 AM »
Hey FOG! Two questions for you this morning about the DF700.

I’m making a version of the table featured in the (delightful) Woodpecker episode 194.  .

I’ve got the DF500 and managed somehow to convince myself this project would be the start of a beautiful thing and I needed the DF700 as well. There are two techniques I can’t quite figure out.

First: the stretchers used to brace near the bottoms of the legs. Since I’m putting two 12x100 dominos in each leg, I need to figure out how to accurately space both mortises in the middle of the leg. I know there must be an easier way to do this, but I can’t quite figure it out myself or get the phrasing right to find a video that shows the technique. Thoughts?

Second: placing dominos perpendicular to each other at the top of each leg. The issue here is that the mortises for attaching the legs to the apron/stretcher (?) intersect in the middle of the leg. As far as I can tell, Alain puts in one set of dominos, lets it dry, then cuts the second set — through part of the now-glued dominos. My questions are (1) is that the technique here, and (2) if so, is it a recommended technique, and (3) are there other ways to do this?

My material for the base assembly is some gorgeous 4x4 Maine cedar from a nearby mill, milled up to 3-3/8” x 3-3/8”.

Curious to hear the thoughts from the group. Thank you for the help!

First of all, that is a great looking table and an excellent video.   Second of all, I couldn’t imagine tackling this project without the DF700.   

I have both the DF500 and DF700.   I sold my 500 after getting the 700, then realized I missed the 500 and bought another one.    They are both amazing tools !

Good luck with the table build.

Forget the DF700 - I want a full-time helper in my shop!  [big grin]
No serious, I own/like the DF700, but the way this base is way-over-constructed you can might even get away with shallower/narrower dominos.

1) Mortising for the stretchers. I assume you're talking about what he's marking at 1:14 in the video. In which case, isn't that self-explanatory? Maybe I'm missing something.

2) Not sure what you're talking about. Maybe provide a timecode for the video or do a screen capture??



Not that you care about my opinion, but I personally dislike seeing the apron endgrain, visible along the long side of the table, as I've highlighted here:


This is easily fixed with a small modification of the design: Have the apron run between the legs (like the stretchers do). The legs then run all the way up to the bottom of the tabletop and then there's no apron endgrain to be seen anywhere. Besides eliminating the apron endgrain, I think visually the table will look better with the legs looking like they directly support the tabletop.

I cannot see why the diagonal supports are required. Seems like over kill.

Snip., but the way this base is way-over-constructed you can might even get away with shallower/narrower dominos. Snip.

The DF700 is sure a good fit for this project, but I agree that the smaller dominoes (8 x 50) with the DF500 can handle the demand of the table as well given the material (3-3/8") and aprons/stretcher construction, provided twin and double dominoes are used:



I also don't think the diagonal structure necessary unless the table is meant to be pushed or rocked around in use for some reason, or some extreme load is expected on the table top.

Could be an aesthetic choice as they add visual weight which is somewhat of a common theme with farmhouse tables.

Thanks all! Couple of things.

First, the table is ridiculously overbuilt and that’s partly what I love about it. It’s also the first table I’ll have ever built so I’m much happier with more than less.

And speaking of that… I’m well aware that it’s possible to do this sort of project either with the DF500 or even no domino at all! If I had either more skill or patience, or maybe a bit less lust for new tools, I’d be a different man.  [wink]

@smorgasbord great tip on the legs! Appreciated. On the stretchers, I’m sure I’m using the wrong word. I’ve circled the areas I’m talking about. It’s basically the mid-board joints I can’t quite figure out.

Mortise and tenon most likely
There are no mistakes....just new designs.

Here's a screen grab from the video:


Seems pretty self-explanatory. Dry fit, mark both pieces (and do it on both sides), then cut at the marks using the same fence height setting.

Good catch! That part I could guess at, but the issue for me is sighting for the DF700.

As you can see from the photos it's less than intuitive versus the DF500. I see the side of the fence where I can sight from but it just seemed to me like there might be a more clever way to do it.

Tilt the fence to 90 degrees and use the fence height to control the offset for both cuts from the co-planer surface. As long as the fence height is not changed all the mortises will be the same distance from the outside surfaces and thus line up perfectly (assuming the stock is all the same thickness).

Just to be uber-clear, here's one of the legs with the mark:


Here's the Domino lined up with the mark (ignore parallax):


Here's the Domino at the end of the stretcher, also aligned with the mark:


And here's a close up:

I couldn't possibly  add  anything to the suggestions/advice. However, I  don't think "overbuilt"  is a term which best describes  this table. I believe the table is designed the way it is because it looks great to the original maker. The diagonals aren't there for strength although I suppose they add a lot of strength. They are a design choice. Not all components of any piece are just for strength or stability. Some are included just because they look good as part of the finished product. I wish I was better at that part of making furniture. About the best I can do is take a design and make some modifications to better suit my tastes.
