Sadly those T-Nuts appear to be US only. However, I could make some fairly easily.

I have used the Kreg Automaxx clamps for three years. I tried a clamp by Milescraft or Anchor (I do not recall which), but it does not automatically adjust for thickness. The Kreg clamps are a little fussy to use, but get the job done.

Thanks John, I’ve now watched his video and like his method of checking for run out - I have an excellent (very flat) level so can use my dial indicator and the level to check the slider.

David Best demonstrates a method of using a large and accurate square with a dial indicator. I use this method, and find it to be quick, easy, and accurate.

You can find this demonstration at the end of Mr. Best’s YouTube video “Sliding Table Alignment for Felder Equipment”. It is about 37 minutes into the video.

It does require a substantial and accurate square, which is not easy to get. I use one made by Lamb Tool Works.

For clamping, I use DeWalt track clamps. You can tip them into the slot instead of always going to the end.?

I also recommend a knurled nut on the handle on the slider. Makes it easier to move it to a more convenient position.

Larry,

That is a very interesting question to me. I looked up the disconnect switch on my K975 and it is rated for load breaking. So I would think that load breaking choice would be safer, however this type of switch is for change over and not for Emergency stop so may not be available with load switching. One would need to research.

Your question made me wonder how many cycles these are actually rated for. Many manufacturers did not even list cycles but I found an equivalent Schneider 32A switch for $287 that is rated for 100000 mechanical/electrical cycles but only for resistive loads. I imagine the $40 replacement switch for K975 is likely not as good.

I was told to not use Emergency stop switch on the machine to routinely switch off the machine as it will wear off. This EStop switch is only switching a 24VAC relay coil, which is nothing compared to switching a 5.5KW motor.

Also confirming what Imran has said, the machines have thermal overload protection internally. As its required by the EU, its safe to assume all machines will have some level of protection. From what I've seen most seem to have Schneider TeSys IEC Overload Relays. Unfortunatley its usually kept under the "Warranty Void if Removed" panel (Illegal in the US under Magnuson-Moss) so not check-able without opening that can of worms if your machines under warranty still.

Hi Larry,

I cannot say if this is 100% true but Felder machines I have helped with have overload protection. My KF700, Dual51 and K975 do have this protection. I am also not sure if my RL125 or FD250 have any such protection, will need to investigate.

I wired my shop myself and had it inspected. I went towards the safe side if I was not sure to avoid any issues during inspection. The CB is to protect the wire as a short could occur between the CB and the machine which would not be protected by the machine overload protection.

If your work is done by a licensed electrician then they should know best.

I recently helped someone with Hammer. If you open the switch box, you will see a 10-16A slide switch (or something similar depending upon motor size). Check label of your motor to determine FLA. Measure machine current during idle and then switch meter to max setting. Make a heavy cut to stall the motor. Check current on the meter. If it is under FLA+ 2A and total is under 16A then may adjust the slide switch to match the current. May help you avoid nuisance trips.

Imran,

Do you know what kind of/if any overload protection these machines have? I'm curious about the mention of fuses in the distribution box. If you were to just use a distribution block and go from say 8awg 3phase input (coming out of PTE010) to 10awg 3phase output to a 10hp machine without any fuses in the mix, are you aware of any issues with that set up?

?

I can only think of the machine being overloaded and drawing too much current over the 10awg but not enough to trip the breaker on the other side of the 8awg.

?

Do these machines have overload protection built in to prevent this from happening? I have had my hammer a3-31 turn itself off plenty of times when taking too big of a bite on a wide board, so I would imagine they have something.

Hi Doug,

You have a disconnect at the machine so, no issue with servicing the machine. I only shared because you asked but I personally would not use such device. It would be an absolute pain to switchover every time I switch machine.

I may have missed it, but if not mentioned already I would like to add. If a single run is made directly from PP to the machines then the wiring needs to be rated to the PP breaker size. If you add a subpanel or distribution box with fuses then the heavy cable is only between PP and the box or panel. Downstream circuits then are wired according to their fuse size. I have a 30A, 20A & 10A 3 phase run from my distribution box. Obviously, the run from the circuit breaker in main panel to the PP also is per breaker size.

I am not a licensed electrician and codes do change somewhat based upon location. Hopefully, someone will correct if I am mistaken.

They are very common and do offer one benefit. They will remove power from downstream circuits. Remember that single phase voltage will be provided by the phase perfect to the downstream circuits even when it is not running. My unit is old but I believe new ones work the same way.

This is what I was envisioning.

In the case of single phase voltage being passed through whether running the machine or not, what is the risk? ?Obviously, you have a live circuit, but is there something else?

I am going thru this Fusion 360 course available for $99 at Udemy. I did not do an exhaustive search but find it fine for a beginner. There is a 30 day refund option and you can preview 5 to 6 classes prior to purchase. Author speaks slowly, so I use 1.5X speed. PY attention as there is also a lower price like $14.99 but that is if you sign up for a monthly plan.
