Re: What options should I get on my machine?
¿ªÔÆÌåÓýChris, i probably make same decision on length compensation vs DRO on xcut unless your work involved a ton of std angled cuts. as for 3ph, IMHO, by all means go for it if you intend to have multiple machines with large HP. if you only intend to have one machine and your work can be done with single phase than that money could be used to do other upgrades like power drive or consider digidrive for shaper, assuming it is available on your machine. single phase machine generally is easier to resell and has higher resale price. Something else to be aware, take it with a grain of salt, as i am new to the overhead saw guard and outrigger.?while it is generally not an issue with ripping, xcutting on outrigger can result in tear out without a sacrificial fence. i am sure there are efficient and safe solutions but I have not yet had time to look into it. because i am familiar with short xcut fence (from my KF experience) I currently plan to just add a sacrificial fence extension to my short xcut fence on K975. for your other question most here use fritz & franz jig for material that is too small to safely cut.?keep in mind that besides the flipstop being on the left side,?with overhead sawguard the xcut fences are ~2¡± away from the blade.?so something else like F&F is needed to register/hold material that cannot be safely cut otherwise. that is another thing i need to make. if the material can be placed against the fence, a block of known length can be used to overcome the flipstop reach. imran?

Re: K975 under table dust extraction problem.
interesting, mine uses 125mm. maybe a usa vs eu difference or the yr of manufacture. my k975 is from 2006.

Imran - the 120mm diameter is the correct fit but I happened to have a length of the more compressible 4" and used adaptors.

And to Lucky too, I fear I have not been as successful as I had hoped.? Certainly the compressible hose stays put in all positions of the saw unit BUT unfortunately the modest S bend in the hose at the 0deg position will surely trap whatever offcuts get past the sawblade and need frequent clearing.

I contacted Felder in the UK and they did not shed any light on the situation.

Re: Another OCD question on 3 Phase wire convention
We should clarify terms "middle" and "B" and "high".
The "high" leg?by definition is?the 208v to ground leg.?? The NEC requires high leg to be Orange. There is no requirement for labeling (A, B, C, L1, L2, L3 etc) or positioning in diagrams or physical panels.? But there are conventions.?? The most common transformer diagram labels the phases A, B, C, like below, labeling the high leg as "B" tap on the transformer.? This also places it in the "middle", since it's a triangle. But again this is just a common convention, not a requirement.? So it's common to put the high leg as the "middle" of breakers and panel lugs.? ?You won't see people using ABC as labels and putting A or C as high.? No law against it, but no one does that.?? But this is not uncommon either, where L3 is the high leg. Note it's spatially in the "middle", but not numerically in the middle: Then there's Joe's question of how to map phases to NEMA plug blades, which typically label the blades X, Y, Z.? I think A-B-C -> X-Y-Z is common and intuitive, but nothing wrong with L1-L2-L3 > X-Y-Z. |

Re: Another OCD question on 3 Phase wire convention
¿ªÔÆÌåÓýI read that the high leg was supposed to be Leg ¡°B¡± in the panel and marked orange.? I have utility 3 phase and the panels were installed by a commercial electrician and the ¡°B¡± leg is indeed marked orange in my panels and in the service entrance. ?

I can report having resolved my under table K975 hose problem by using 4¡± diameter flexible hose that compresses along its length by 50%.? This contrasts markedly with the hose I have from Felder which is of the heavier type and which compresses very little along its length ¨C perhaps an inch per foot.? Without this feature there is much distortion of the hose when the saw is moved from 45deg to 0deg.? I cannot explain why others, Lucky excluded, seem not to share this problem which involves the hose separating from the saw unit when angled.? ? In Imran¡¯s case his pics show considerable longitudinal compression but how David Best has managed I know not. Perhaps the Felder hose specs have changed over time? I found that a 38¡± length of hose does the trick although with moderate ¡°S-bending¡± at 0deg which will no doubt hasten the decay of the plastic.? Phil? |

Another OCD question on 3 Phase wire convention
I have utility delta 3 phase with a high leg.? It's correctly connected to leg "B" in the panels and labeled orange.? I am pulling black, red, and orange conductors to the receptacle as well as ground.? The Hubbell receptacle has X, Y, and Z terminals.? I'd like to wire all the outlets the same.? Is there a standard for which terminal would be the high/wild leg or leg "B"?? My gut says "Z"
