42F and cloudy @ 14:00, heading up to around 50F for the high at around 19:00 this evening. Under a Freeze Warning for tonight ... which is a good reminder of why one doesn't want to be planting things that are vulnerable until after 4/30.
Late night last night but productive day yesterday.
Started off by running down to the hardware to pick up that roll pin. Of course they didn't have one 1 1/8" long, 1 1/2" was the next closest size. So I installed that and then cut off the unnecessary portion with a zip disc in an angle grinder. Managed not to hit anything else ...
After that I got the masking tape pulled off the the 3 phase motor and the cord clamp installed:
Paint seemed dry so I went ahead and got the motor mounted in the cabinet, belts and fan installed, and power cord run to the motor:
Running the wiring ended up being quite a PITA and pretty time consuming.
First off, the junction box on the motor itself was facing the wrong direction - which I only realized after getting it mounted in the cabinet - and had to be rotated to face towards the front. Given that the opening on the junction box is more or less facing down and you can't see into it, the installation had to be done using a small mirror, kind of working in reverse and upside down.
In hindsight, it probably would have been better to construct some cribbing to set the motor on inside the cabinet and rotate the junction upwards to be able to see into it and hook things up. But I'm not sure I would have had enough strength to pick it up off the cribbing to hook it to the mounting bracket if I had done that.
In any event, I managed to reverse the mounting and get all the wires connected with wire nuts, except for the ground which had a ring terminal on it and was connected to one of the mounting screws for the junction box itself.
Close up of belts showing the sequential numbering, which I'm guessing shows they were all adjacent siblings from the same lot:
Next I got the fan shroud installed:
The attaching screws were soaked for about 30 seconds in acetone to soften up the paint and then wire brushed to bright metal.
View of interior showing wiring after all that was done:
There is sufficient wire length for clearance, other than fully tilting the blade when the blade is all the way down. Possibility that that can be resolved by clamping the two power cables to On/Off switch for the VFD to the cabinet to hold them out of the way. Will have to see.
Next up was wiring the motor and input power to the VFD. The ring terminals I had were slightly too wide to fit into the terminal block so I filed those down by hand.
The terminal block sits just above a plastic panel that is part of the VFD's case that separates the (high voltage) circuitry in the back of the case from the user accessible portions in the front when the cover is removed. Since I was using ring terminals rather than forked spade terminals I had to remove each of the five screws (two for 220v input power, three for 3 phase output power)
Of course, I managed to drop one of the screws behind the plastic panel while taking it out. Fortunately the screws were magnetic and I was able to retrieve it by using a magnetic pickup tool while tilting the cabinet to the rear and propping it up.
After getting that all hooked up I moved on to wiring up a plug on the input power cord and a corresponding receptacle on my 220v extension cord.
Once that was done I connected the input power cord to the receptacle and flipped the power switch on the saw, hit the "RUN" button on the VFD and was greeted by this at a bit past 03:00:
On the menu for today will be:
1. Programming the VFD so that the saw's motor can be turned on and off by an external switch so that it doesn't have to be started from the front panel of the VFD + getting the switch wired up and testing it.
2. Install the blade and the dust chute.
3. Some clean up in the shop and put tools away.
4. Measurements taken for mobile base and start cutting the steel for that.
5. Maybe continue working on cleaning up the table and and extensions if there is time.
Hope everyone is having a good day ...
