It's a contact closure in 'Auto' mode.? The whole GRIT Magswitch is inside the Felder. The power to the switch comes from mains on the RL160. Two other control wires run from the switch to two terminals in the RL160:  You can also see the toroid that goes around one of the power wires going to the blower motor. When the switch gets a signal from the GRIT Hub, it closes that circuit. The 'latching' functionality in the switch keeps the circuit closed until the RL160 is told to shut down. The toroid monitors the current in the circuit. In other machines (like the AD941), the current sensing tells GRIT the machine is running. I have no idea how other versions of the RL160 would be wired, so your machine could be different. John Kee helped me through this years ago, and there seem to be other threads how to make this work. When John guided me through the installation of iVac Pro switch, it was a little more complicated. The iVac Pro switch fed power to a 120 V fan relay (https://www.amazon.com/gp/product/B0071NAYUU/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 ). This closed the circuit and turned on the RL160. Both worked well, but the iVac Pro got wonky every now and then. I have no experience with the durability of the Magswitch.

My Oakley H48 is less massive but still about 2000 lbs.?? In my world the keys to edge sanders are a stout flat table and a stout platen that doesn't have twist or can't be induced to deform under pressure.? The two also need to maintain 90 degrees without
fiddling. My Oakley has a 7" platen and I wish for 8" but life is a compromise.

If I were after a new edge sander, I would definitely buy a Ritter. ?I owned one for 15 years and loved it. Built like a tank - 700+ pounds. ?Made in Michigan. ?Here is the version that makes the most sense IMO, but they offer other models/sizes as well:

On both the HS950 and the Baleigh, the platen is made from a 1/2" thick piece of steel? (NOT sheet metal, lol).? I have found my HS950 to be super accurate for edge sanding as well as sanding 45 degree miter corners with the Felder miter gauge.
The Baleigh is not a 100% copy, though. There are several items where the Hammer HS-950 is better.
- Better table height adjustment - only one clamp to loosen and table remains perfectly level as you adjust up and down (this is important when the platen is adjusted down at an angle). Baileigh requires two clamp knobs and you need to make sure to keep the table perfectly level when adjusting up and down.
- Better dust collection. Hammer essentially has a 5" dust port (120mm). Baileigh has 4" dust port.
- Better motor. Hammer has a 3HP 2.2kw 12.4A (based on motor plate). Beileigh specifications say 2HP 1.5kw 9.5A.
- More stable stand? Hammer base/stand extends to the full width/length of the machine. Baileigh stand is smaller.
- Better miter gauge (although you have to buy this extra, the miter gauge is much better than what comes with the Baileigh).
There may be several other things on the Hammer that just "feel" better, but I haven't used the Baileigh so I can't comment. So, Hammer is a better machine, but you are going to spend about a $1,000 more (especially when you add in the accessory miter gauge).
That being said, a couple of points for the Baileigh:
- Has an edge support shoe that can be mounted to the table for edge support when using the sander fully 0 degrees flat
- Has a bit of storage available in the base (although you could build your own storage base on the Hammer.
One of the big advantages of the HS950 / Baleigh is the angle adjustment.? Most edge sanders will allow you to adjust the angle of the table down to a max of 45 degrees.? On the HS950/Baleigh machines, the platen is adjusted down instead.? This allows you to sand an angle that is more extreme than 45 degrees.? The platen on these machines will actually lay down flat to where it is parallel with the cast iron table.?

Re: Riff sawn / slip match oak ply
I¡¯m in the northeast (probably should have mentioned that), I¡¯ve tried a few local places but have come up empty so far. I¡¯be got some feelers out and hope to hear back after people get back into work from the holiday.?
I¡¯ve got a call into Atlantic plywood as well.?
I might have to get some shipped in - I¡¯ll give Amy a call if I get stuck.? ?

Re: Crosscut scale issues
This is amazing information, I'm fairly certain this piece is missing. Thank you all!?

Scott, how does it start the RL? ?The start button is supposed to be depressed until the unit comes to speed ¡ª is their control designed to do the same?

I did have one Nordfab gate that was sticky. It didn't open and close like the others. This one also happened to be new. GRIT instructs you to lightly file the edges and I gave them a coat of dry bike lubricant and it worked perfectly.

This is the mother of all edge sanders. It's the one you want if you have room and it's not going in a basement LoL. Probably the most used machine in my shop.

Re: Riff sawn / slip match oak ply
If you are in north east try Atlantic Plywood. Just made wall panels from this product, mdf core but they might have same in veneer core.?

In my last shop I had the Grissly version at about the same price point. I bought the HS950 when I moved. I had no issues with the Grizz, and see no real advantage to the Hammer. In fact the Grizzly had handy storage underneath that I will have to build for the Hammer.

Quite a long time ago, I purchased the original Ecogate with vibration sensors. ?Then I upgraded to the Greenbox 12. ?The gates changed to be more beefy and enclosed with time, and then the wire used changed. ?At one point, you had to run a wire from the Greenbox to the gate and a separate wire from the Greenbox to the machine. With the current gates, you can run 1 wire to the gate and from the gate to the machine... better.
Last week, I had a problem with my jointer gate and to troubleshoot, you can't use an app. ?You have to own a PC with the software installed and connect with a USB - serial cable.. ?I am a Mac guy, and so this is what is needed.
EcoGate is local to me and they sent someone to troubleshoot. ?Problem with bad motor and that was replaced. ?There was another very old gate that was making terrible noice and it just needs to be replaced --- over $500 for a 5 inch gate.
For me, I have overall had good success with EcoGate, and at this point I am locked into their system as I see no compelling reason to start over with another brand. ?I started with EcoGate when to my knowledge, that was the 1 system to get. ?However, if I did not have the EcoGate, I wonder if I would have selected GRIT instead. ?Not sure of the pros-cons of each system.

Thanks, Scott! I probably should have done that as well but when I searched for Grit, I saw so little activity on the topic, I flipped a coin and decided to go back to an earlier thread to ask my question rather than start a new thread.
?Question: You mentioned Norfab gates with solenoid-operated switches. Were these gates you already had and integrated them into your new Grit system? Thanks.

Scott,
Agreed!
I used the e-stop triggers for the 3ph machines.? Really simple actually.??
Joel was awesome to me also, as was Jaclyn.? They were available to help via face time at one point.? Joel pushed me firmware updates also and decided to send me updated e-stops with an internal change they preformed.
I had an issue when the table saw was going through star-delta start and when the third phase would kick in then the DC would spool down.? He showed me how to change settings to eliminate the issue with no downside to performance.
It isn't cheap, but I think it is less than the competition and really flexible to use.

Starting a new topic here to avoid hijacking other threads and allow a more focused discussion.
I've had bits and pieces of automation in my shop for several years. The pieces were mostly iVac. A couple blast gates, and an IVac Pro Switch to control my RL160. They worked fine most of the time. It seemed sort of piecemeal, but it worked. One aspect that kept me from adding more blast gates was that I was spending money to buy the automated gate to replace an already pricey Nordfab gate. The iVac gates were so-so IMO.
Over the past several days I did a full install of a GRIT automation system. It was pretty easy to do and the individual pieces are real quality. One thing I hadn't expected was the exceptional service from GRIT. I have literally never had friendly, helpful service like this. Joel and Jaclyn made it even more a pleasure to install everything.
One thing I wasn't expecting to do was integrate my two dust collectors. I have the RL160 that serves the AD941, the tablesaw, bandsaw, and floor sweep. Earlier this year I added a Harvey Gyro 700. I'm using my CNC a lot now and it was really overkill using the RL160 for hours to keep the CNC jobs clean. I just switched hoses to each collector when I was doing a different type of job. When I was discussing the system with Joel at Grit he suggested adding branches to each collector. I hesitated for a while because of the added costs involved (Nordfab and GRIT), but decided to make the whole system work as a unit.
Long story short, the system is working really well. For the GYRO and RL160 Joel had to add a functionality to my collector switches which he did in a day and pushed them over to my system for automatic updates. Now, when I turn on the CNC, it triggers the CNC blast gate, the Gyro 700 blast gate, turns on the Gyro 700 and closes the RL160 blast gate (another functionality Joel added in a day and pushed over). It's a great system.
A few aspects I hadn't counted on but love:
1) GRIT support. Mentioned above, but they are amazing.
2) The software makes it so easy to understand how the whole system is set up, and is easy to customize instantly, No more dip switches. I can also turn on/off pieces in my shop from in my house.?
3) All the pieces are heavy duty. The 3 phase switch for the AD941 looks like it belongs in a factory. The gates are Nordfab gates, with solenoid operated switches. The 220V triggers for tablesaw, bandsaw, etc. are really heavy duty with L6-30 plugs.
I'd do it again in a heartbeat.
