Re: Dado Help Needed Please
Bill,
A different way to explain is that the arbor length is fixed. You basically need to add spacers on the arbor so that your total stack is wide enough for the flange to apply securing force.
I was told that if the blade clears the rip side then you may add all spacers in front. I still prefer adding some on both sides.
The exploded diagram for my K975 shows the shim set needed for dado (3, 6 & 9mm). If you are not sure that you have the full set you may check your saw book.
Happy Dado-ing ?
Imran

I have removed the saw blade and the spacer behind the blade. ?I only have the 12-19 dado set.? I have 1 each of 2, 3, and 4mm spacers.? I wish to cut a 12mm slot so I am not adding any spacers between the cutters since that is the smallest

Re: Dado Help Needed Please
Bill,

My KF700 has an interior spacer when the saw blade is installed, but I must take it out when using the dado set.? No interior spacer is needed as the dado clears the saw without one.

There is a spacer inside too. Whatever size allows the dado blade to clear. I have a Kappa 400 and I need to remove another piece that is part of the blade opening so my setup I’m sure is different. Sorry I can’t help more

I believe you should also have a spacer to move the blade out further on the arbor - I can’t remember the size but some one I am sure will chime in.? That may tighten it up for you
The setup on the left us for a regular blade, the one on the right is for the dado set.

No problem, like Michael said you may need one on the inside to push the stack out a little depending so check your clearance?

Jason (et al if there are any useful thoughts out there)
I just got back from a near final design meeting for a big (for me) cabinet job. ?kerfdesign.com style. ?I think we’ve agreed on mitigation for warping (frameless doors) but it remains a concern. ?I’m going to use 3/4” for carcass back, biggest doors are 22 1/2” wide and 34 tall and they’ll each have a fixed shelf. ?Bringing it up lest you’ve discovered/experienced anything new on the subject. ?Aside, I’ve bought a Mafell 26cc to cut dados (I’ve got an older KF700sp so no dado arbor). ?I’ve played with it and it does a great job. ?The blade has scoring cutters on each side so does a real nice job without tear out on the rebates.
Thanks, ?Mike

Re: What air compressor for Mac's clamps?
Hi, Mike – ? I have a similar California Systems compressor (the 10-gallon CAT-10020C) and use that not only for my Big Squeeze clamps, which are similar to Mac’s, but also to operate my Nordfab automatic blast gates.?? Works fine, though the compressor kicks in about every 15 minutes or so while I’m at the slider. ? -Rob

I do not have one but certainly there are ways to reduce the noise from a given portable compressor.

Re: VFD issue with 3 Phase power supply
Update. Another utility trouble shooter tech came by last night. This one was much more knowledgeable. He did not have a power quality meter or oscilloscope but he escalate to have a power quality tech come to test. More importantly he told me that “I didn’t
tell you this but we’ve had a ton of
Issues with the transformer we installed here”. He also told me that the power line behind my property where my transformers connect is scheduled for replacement and that they would only do that if there was an issue with being able to balance it. Also
learned that if you have more than 40mV of drop across fuses in a panel the fuse is bad and will fail.?

I am also going to lower the current limit in the programming to see what happens as it’s a really easy test.? The new VFD is rated for like 19.6A output

Some more background.? I brought the idea of variable speed to increase suction on small ports to Robert founder of Oneida at the Vegas show like 10
years ago.? We traded a ton of emails and he swore me to secrecy and the idea became the Oneida Smart collector which won innovation of the year at either Vegas or Atlanta.? In appreciation for the idea Oneida upgraded my collector to a 5HP Smart collector,
single phase input.
?
Lately I was having some issues with the 10 year old VFD shutting down and Oneida was very helpful and we found that for some reason some of the parameters
were corrupted in the old single phase VFD.? Through this process I learned a lot about programming VFDs and I realized that the programming of the VFD was set to limit output current (the current limit of the original VFD) to 8.9A. The 5HP Baldor high efficiency
motor is rated at 11.8A.? In running the VFD and watching parameters I realized that the motor was never even getting to 60 HZ due to the current limit.
?
So I decided to upgrade the VFD to a 3 phase input. Same series ABB but at least with the ABB ACS310 series they are built as single phase input or
3 phase input.? So I ordered an ACS310 5HP 3 phase input VFD.? Super easy install as the programming just copies over.

But the new VFD faults.? Last week it would fault after a few minutes.? When measuring the input currents the delta then was about 30%.? Over the weekend
it didn’t fault at all and the current deltas were 20% or so. ?ABB sent a replacement VFD and it did not solve the issue.? Last night would get faults in less than a minute and the current delta was over 40%.
?
More background:
-
I have 600A of Utility 240V Delta 3 phase power.? Two transformers in my front yard.? New install one year ago with new buried lines from front yard to workshop.
-
The workshop has a 5 Ton AC, 1.5HP pool pump, and sometimes an AC and water heater on for the guest house, plus 2,200w of LED lighting.? I doubt I’d ever see more than 100A or load at
one time.
-
I have a 3 phase shaper and a 3 phase bandsaw running in the shop with no VFD and the currents are pretty consistent on all lines.
-
Voltage at the panel and at the VFD for all three legs is very similar.
-
When the utility came out this week to test I started as many loads in the shop as I could and we had 0.2V difference for the two transformer legs measuring 121.3V and 121.1V.? Leg B
being lower
-
It seems like the average current across the three legs is the same each time I measure even though the delta between legs can be quite different each time.
?
Can a phase error between the phases cause lower current in one leg?
?

More thoughts after rereading your post.
You mention original VFD as single phase and new as 3 phase input. This could be important if you are running with single phase input.
At first I thought you were running new VFD with single phase input but you report 3 input currents. Just curious, why are you using a VFD with 3 phase input on a dust collector with a 3 phase motor?
Another thought. I am sure you know this, on a VFD, the single or 3 phase input is used to create a DC power supply. This to me means that there should not be a repeatable phase relationship between input and output currents. A resolution
to your problem can help further our understanding of how these things work.
?
I had to replace the VFD on my dust collector. It was an ABB ACS310 single phase input feeding a 3 phase 5 HP motor. This was from Oneida and because of the single phase supply they set the max current at the limit of the drive which is below the amperage
of the motor. Anyway the new drive, an ABB ACS310 5HP 3 phase input VFD, faults with my utility delta 3 phase supply. The fault is due to uneven current on the input. I’ve spent hours measuring and testing and worked with ABB tech support several times. The
key test ABB had me do was to swap two wires to see if the low current moves. It does not so ABB said not the drive. But they did approve a warranty swap. With the replacement I see the same problem. With leg A I get 20A leg B 15A and leg C 19A. Leg C is the
wild leg. The voltages under load for legs A and B are within 0.2V. I also had the utility out and then measured and said all good on their side. They did not put a scope on the lines to see is I have phase shift issues. Could a phase different between the
lines cause a 20-25% current difference when the voltages are the same? ?Also I have notices that the current difference changes. Worst was tonight with 22A, 14A, and 20A.?
also I have two other 3 phase machines that run and the currents measure the same on all three legs for those machines. I also tried running the VFD with a new breaker and also on a different line. ABB agreed to swap the drive because the currents are the same
on all legs with non-VFD machines. ?
the only thing I can think of is the phase angles between the three legs is not 120 degrees. HELP

Re: What air compressor for Mac's clamps?
I have the small California air.?? Had it for a couple of years now and works well.? I have it connected to and use it for my Felder clamps, RL 160 and CNC (uses air to assist the lift of the three heads) and have not had any problems other than some leaky connections. ?

Re: What air compressor for Mac's clamps?
Had the same thought in mind recently when I noticed this at Harbor freight when expanding my blue toolbox collection. For this price they are accessories for the clamps.

Clamps don't need a lot of CFM? unless your hoses leak? like sieves.? I be? one of those portable ones would do fine

Forgot to mention that the frequency of sound is also much lower.
