Re: Slider support leg question
#sawsetup
So I have the slider adjusted to .005 above the cast iron table during 75% of its travel.? But when the slider is as far to the front of the blade as it will travel, the slider is .018 above the cast iron.?
The same at the other full extension although not quite as much due to the support leg.? Is this the best that I can hope for with only 4 bolts for adjustment? |

Re: Langzauner Sander Delivery - Warning on Machinery Max Palletization
¿ªÔÆÌåÓýFelder isn¡¯t so great either. My CF531 was under-packed with boxes just chucked inside the outer plastic wrap which rubbed on the machine wearing through the paint. I¡¯ve been waiting since July to get the right color touch up paint from them, though they have sent me two cans of a lovely metallic silver in case I ever need to make a wooden sword for a theater production.? My machine hadn¡¯t broken through or loose from the pallet, but I had a bunch of little stuff that should have been done a lot better.? On Dec 17, 2020, at 12:37 PM, David Kumm <davekumm@...> wrote:

Re: Langzauner Sander Delivery - Warning on Machinery Max Palletization
That's really poor. Though good to see I wasn't overly unlucky with my recent pallet mishap. I had a Hammer N4400 delivered via the pallet network in the UK. It was shipped on a 1x1.2 pallet vertically and had fallen over in transit. Hit the fence bar and cracked the casting at the bottom (but remained attached, managed to bend it back, some serious casting to take that kind of hit and not shear, the M10 bolts were at 90degrees though hah). Filed off the grooves in the bar (looked like it hit concrete, sharp sand/concrete dust embedded, looked like it bounced a few times too...), fence bar was remarkably perfectly straight still. No bent sheet metal or marks to the paint.
But yes, above is particularly poor... |

Re: Motor plate experts
In Austria (where this is made) and western europe (main market) the 3 phase standard is 400V.? ?So the manual says 400V, because that's the default.? Your specific machine was configured for US market, where 480V is the parallel standard.? So this is a motor for 480V 3-Phase power.? It says 460V, because equipment is designed to a "utilization voltage", not the distribution voltage (it's just assumed there some loss within the facility from the point of power to the actual equipment, which is often hundreds of feet).? That's the same as the ubiquitous confusion between 115v (utilization rating) and 120v (distribution rating)
The other motors are dual-voltage, 230/400V.? ?They also say 218-242, which is just saying 230V +/-5% (5% is the standard allowed deviation from nominal voltage). Likewise, 380-420V is 400V +/- 5%.? Since 5% is the universal norm, putting 230V and 218-242V on the nameplate is purely redundant.? These motors will have 6 terminals, the start and end of three windings.? When the windings are connected in delta formation, the supply voltage must be 230V.? When the windings are connected in star/wye formation the voltage must be 400V. So two motors you just hook up to your 3P power (using correct motor terminals), and the motor needs a 240->480 transformer.?? |

The hum reminds me to turn it off and to be really careful.? High voltage is scary.? I had a 600v machine and spent a lot of money to convert it as all the controls were 600 as well and I'm absent minded and clumsy.? Dave

Joe, if that machine can be run on low voltage, you may need to boost your voltage.? 277v less 10% brings you down to the 250v minimum.? the motors will likely run warmer and may be fine but is it easy and cheap to
put two? buck boost 32v transformers, wired open delta on the machine to get within spec.? I did this with my Robinson.? Two 1 kva transformers handles a 7.5 hp motor.? I bet the motor is wired 480 so looking at the starter will tell you how complicated it
is to swap that for the lower voltage.? If you step up to 480, the preferred transformer would be a three phase 240 delta to 480 wye step up isolation unit.? Some transformers can be run in reverse but you need to understand the grounding issues when doing
so.? Generally if the plate on the transformer says " low and High " you shouldn't reverse.? If it says " primary and secondary" it may be OK but should be checked by the manufacturer.? An auto transformer will be delta to delta in your case and be a smaller
unit and cheaper but may not deliver quite as clean power as an isolation transformer.? Clean is my layman's term and not technically correct.? Lots of machines run fine with an autotransformer but they are more often used when the voltage spread is less.?
Buck boost transformers are autotransformers. ?

bar. I had read several message threads here about potential fixes but so far as I gathered no one had arrived at one. I had contacted Felder about it and was assured it was nothing abnormal, and there was no particular fix for it.
The squeal?only happened for me when taking sequential passes on boards, not on a rough surface, so my thought was that the drag of a smooth board on the pressure bar was leading vibration in the entire bent metal bar. I found that i could temporarily alleviate the problem but putting paste wax on inferior edge of the bar, but that only lasted so long.? So I did two things. First, I attached a thin layer of foam to the surfaces of that metal bar in areas where it wouldn't interfere with any moving parts. I used some left over shelf liner material to do it. Then I filled the little crevice created by the last bend in the metal plate with hot glue (the area circled in blue on the diagram). Those measures really dampened any vibration in the plate. As a final measure I put a piece of Low Friction tape that I got from Lee Valley along the bottom edge where the bar rides along the wood.? I'm not really sure which of these fixes was the one that did the trick, I'm guessing probably the low friction tape was the key given the paste wax experiment, but between all those measures the high pitched squeal is completely gone. What a relief, it was driving me nuts.? Anyway, thought I'd share in case anyone else out there is having the same issue.? Incidentally, just placed an order for a k700 slider, so i'm sure i'll be hitting you all up with questions in a few months when this thing arrives.? -Dave |
