Domino 500 Additional Stops (Update)

[iamnothim]

[size=12pt]
BIG ERROR on my part.
I should have understood the Domino depth mechanism and made some measurements before starting this thread.
[scared]
The set of nine stops Only Adds Nine additional settings.
When I measured the bit depth with a stop inserted the Domino plunges the Exact Same Depth for each setting on the machine.  Thus with a stop, it doesn't matter what the depth is set to on the Domino, you will get the exact same depth for that stop.  I don't know why, but you do.

ORIGINAL POST:
I received a set of Woodpecker Domino Depth Stops today.  The stop goes on the Domino plunge shaft to limit the travel.
There are nine CNC stops in the set providing 45 additional depths to the five settings on the Domino 500.  (I did not do the math to see if there are redundant values.)
The minimum depth for a 5mm bit is 0.256"  6.5mm  (EDIT)

I'm waiting for the metric version to come out. [smile]

**UPDATE FINAL PRODUCT (September)**

From Woodpeckers...? (www.woodpeck.com). Where did you find out about these?  ???

I must confess Woodpecker's sent me a prototype.
I suspect they will go into production soon.

 

[copcarcollector]

You are so lucky!!!  

I will watch for their announcement.

Do they attach in any way to the Domino, or just slip onto the shaft snugly?

They are precisely CNC'd to glide loosely on the shaft.

forgive my ignorance i am not sure what the advantages and purpose of these are?

They would allow someone to plunge to a specific depth that is not one of the presets (such as making an 18mm plunge, as the closest preset stops are 15mm and 20mm).

The 9 CNC sleeves will give you 9 new depth settings, not 45. These depths come from the table in the Supplemental Manual. If these are prototypes and they are looking for feedback, you should tell them they printed the wrong numbers on the sleeves. Instead of saying 27/32, it should say "1/4", for example. The actual plunge depth is the inverse of the length of the sleeve.

Seems like those would be easy to make with dowels and holes drilled into them.  As I understand it, they don't really have to be 'snug' to the post as they are only spacers, correct?

OOPS - Rick posted while I was composing.  Even easier with PVC pipe!

Thanks Rick!

I had just corrected my error when you posted.

Tough cutting PVC to a 32nd.
I read the supplemental manual a month back and though CNC AL would be a more elegant solution and asked Woodpecker about it.
I haven't gotten my head around why the plunge depth is the same for each setting.  I'm not taking my 500 apart to find out.

Good advice

It doesn't need to be accurate to 1/32". That's just from the conversion of 28mm = 1-3/32"

[huh]
The table from the supplemental manual you posted has nine stops in increments of a 32nd.
Sure you could have other values, I was just following those.
Accurate is usually better.

[huh]

Well, if I incremented the depths by 1/16" there would only be 5 rows and they wouldn't fit so neatly into those 3 little "table-etts".  [tongue] [tongue]

No, seriously! That's why there are 9 entries. [big grin]

OK... I can't help myself... [tongue]

I like stuff that is well made, and accurately machined.
As such, I bought one of these.  Was I mistaken?

 

[NiteWalkerGR]

I'll be watching for these stops. I have some PVC I can use for now, but I like things that are finely machined as well.
They're less likely to be thrown away as a scrap of something.

I'd be concerned with metal stops scratching the tubes.  Delrin would be a better choice IMHO.

I asked Woodpecker about using Delrin and here is their response:

"Concerning Delrin. Like most plastics, it has a high coefficient of thermal expansion. In other words the length will change ever so slightly with different temperatures. For instance if the bushing starts at 1.000” long and is machined at 80 deg F and then used in a 50 degree shop, it would be about 1/64” shorter."

Hence CNC AL.  The machining is impeccable and I have no concerns with scratching.

Interesting... although the ±1/64" thing seems silly when you think that the depth of the mortise has to be measured in the middle due to an oscillating cutter and it is a bit deeper for glue relief.
