I am thinking about trading up to a k700p with the 2500mm slider.? Is cutting a sheet of melamine which is 2460 long do able on the saw including the scoring blade.? I currently have a k3 winner which has been a great saw.

Re: Used KF700 year 200 price check
Thanks Patrick & Imran for your thoughts. I was excited to see this saw come up in the Seattle market local to me, but then found it to be so-so in person.
It's missing an eccentric clamp, table saw blade guard, and anything for the shaper beyond a fence: no hold downs or other safety feature items, which I would have thought an original shaper user would have thought necessary (even my Rojek has a bundle of different helpers for the shaper). The current owner only used it as a saw. It seems like the under the table shaper dust collector "basket" is half broken, unless it's normal that half the sphere is missing. Only the half connected to the dust tube leading to the exterior is there, so a lot of chips would fall down onto the spindle/belt, that seems wrong. Although the exterior of the body says it can take a high speed spindle, the E-shop part numbers suggest only more modern ones are stocked. I will have to contact my Felder salesperson. It's a pretty expensive part, I think I would probably just work a router table into an outfeed table extension (to utilize the slider) and keep the shaper for shaper sized cutters. That's what I did with the Rojek.
The outrigger table is all fine and present. Just no eccentric hold down.
The 3 phase is the problem - due to limited power at my subpanel, I talked to an electrician today. He advised me I should turn off my heat when using the saw and RPC, or I might blow the main under initial motor loading. No other tool in the shop exceeds 4.8hp (3.5KW) single phase, and most are less, so up until now my panel was always ok. It's 80' of difficult conduit pull, mostly underground, so I won't be upgrading. I know because I did it all myself when I was younger and more energetic.
I agree about the 80"¡I was really searching for 98", to just squeak by with sheet goods. I'm already annoyed on enough occasions with the limits of my 5' saw, and 80" isn't much better. 10' is really common as a used saw, even 5' is somewhat common on the used saw-shaper or 5-in-1 market. But 8' seems really rare. I think this length issue (along with the RPC) will keep me looking for a used 8' while I save for another year or so to purchase new. My used budget is $5-6k at present, and I know new is $8-12k, depending on make and manuf. So I'm halfway to new.
Great site (and so many more users than the tiny Minimax iogroups!).

I am looking at selling my k3 winner 2000mm slider and purchasing a k700p with the 2500 mm slider.? Would the 2500mm slider on the thee k700p by able to cut the untire length for a 2460mm long sheet of melamine.

Re: Adding fence to bandsaw?
Joe,
I mounted Aigner rails on my bandsaw for Aigner pressure wheels following Aigner directions. Later I realize that my felder cast iron extension tables don¡¯t fit. Maybe, I could have mounted the rails differently to make both work.

Re: 20¡± Northfield bandsaw
Guys, you mention an Iturra spring. What makes it good? My Wadkin DR36 needs a new tensioning spring as the original is either worn out or was never stiff enough. But I have no idea how to buy springs.?
Can you give me any guidance on a suitable spring purchase for a large cast iron saw from the 1940s. ?
Length? ¡°°Õ³ó¾±³¦°ì²Ô±ð²õ²õ¡±? ID and OD?
Coil pitch? Compressibility?

Those higher resaw heights is where tension is a lot better than relying on guides to hold blades.? Is it possible to buy a 3/4" blade and try the machine before delivery?? The NF will be a sweet second saw, I'm just not sure about the 12" resaw.? My ACM 18"

Elliot,
This ebay machine was posted earlier on this forum. The seller is delusional as he thinks this machine is worth over $20K.
If you look at picks you can tell this has dovetail (S) coupling
which, I gather from posts, is less desirable than F (Flat) coupling
because accessory are still available.

Something like this already exists in the form of "light-field" cameras (). Software allows you to choose focal length and depth-of-field for an image any time after the scene is recorded.
Lytro's light-field camera was the first consumer-market version that I saw. (My next-door neighbor and a former colleague were involved in developing it.) Unfortunately, it wasn't a commercial success.
I'm told that large-scale versions of this technology are used heavily in the movie industry.

Well, I put "AI" in scare quotes to convey that's it's just a loose term, it's not a technology.? The point was that the iPhone is combining two distinct concepts -- binocular vision and facial/object recognition.? The first is arguably "just math" and that latter is "AI" (where AI just means machine learning/neural nets)
My other point is about "simulating bokeh".? ?Bokeh isn't a standard of physics, it's an aesthetic thing.? Here's a typical definition:
In photography, bokeh is the aesthetic quality of the blur produced in out-of-focus parts of an image. Bokeh has also been defined as "the way the lens renders out-of-focus points of light". Differences in lens aberrations and aperture shape cause very different bokeh effects. Some lens designs blur the image in a way that is pleasing to the eye, while others produce distracting or unpleasant blurring.
Obviously you know this, but the phrase "simulating bokeh" could easily be misinterpreted as implying there there is?some optical standard of bokeh that the iPhone is trying to simulate, which isn't really the case.? A Canon and a Nikon of identical optical specs will produce different bokeh.? Even two instances of the same lens can produce different bokeh.? Photographers debate bokeh quality ad infinitum, but it's an aesthetic debate.? It is not a scientific debate about whether a Nikon or a Canon or a Sony produces the most "correct" bokeh, because there is no such thing as "correct bokeh".

I'm looking for a used CF631. I'm hoping to find someone on this forum who is either selling one or has a friend that will sell one. If you know of one, please let me know! You can email me at elliot.consigny@...Also, during my research I've seen the importance of having the F coupling of the S coupling. How can you tell from pictures which is which? There is this one on ebay- What do people think of this machine? I'm weary of having to do a lot of restoration/work on a well-worn machine.

Re: 20¡± Northfield bandsaw
Sounds like a plan.? Delivery is worth 500 at least.? The spring will cost about $25 worst case.? Start with a decent bi metal 3/4" blade and get to know the quirks of the machine.? If you decide on carbide but the tension is iffy, the laguna Resaw King has
a thinner band than the Lenox so it might be an option.? I prefer the lenox but the .035 band will be at the high end of what the saw can handle, even with the new spring.? On my Yates, the spring sits on the casting but you want to check that whatever supports
the spring can also handle the additional load.? 2-3 varitooth should be good.? My Olivers run at 6750 fpm which is fast but works for me as I'm not very patient so feed rate can be greater with the extra speed.? Dave

?Thanks Dave, does not include the power feed but he said he could deliver it as he is only about 15min away. Northfield got back to me and below is what he said. Pretty cool to get all the history, the guy selling is the one who bought it!?
I am looking at this as a under 12-14¡± resaw to replace the laguna 14/12 which actually isn¡¯t that bad as long as its under 7¡±. I would eventually get a larger saw but for now I don¡¯t have the space then use the 20¡± for ¡°scroll¡± work.?
As far as blade selection i was thinking carbide but I think there was a recent discussion on non carbide blades that dis a great job at a lower cost, what your opinion?
Reply from NorthField below,
S/N 612332-I is a 20" Bandsaw that was shipped as a "motor Base at Side No Electrics" Machine.? That means that it had no motor, belts, pulleys, belt guard or motor starting equipment.? Those items
installed at the time of sale by either the distributor or customer.? It also had SZ#0 Carter Guides.
?
It left our Plant on 10/03/1961 and shipped to Enterprise Machinery, one of our Distributors in NY State.
In?2019, Adam Geraldson in Essex Junction, VT?bought it . It sold for $475.00 in 1961.?
In 2019, We shipped tires and a new #0 Carter Guide.
?
A.? $2K is Fair.
B. ?Don't know what's on it for motor HP or Blade Speed.? You want to be under 5600 feet per minute to resaw effectively. 5,600 fpm on a 20" wheel equals approximately 1,070 rpm. Shoot for 900 rpm.
C.? None of these saws can provide the tensions the blade people ask for.? The Guides hold the blade.? Don't worry so much about tension.

If condition is good, a decent deal without the feeder and a great one with it.? As a resaw it will be OK but not in the same world as a heavy ACM or Centauro 24" or a NF 27 or32".? It will likely handle a steel blade but I doubt it will tension a carbide blade
if that is what you intend.? The cast iron saws in the 20" range had larger tables and were more of a scroll type saw with occasional resawing.? The 30" saws were built for both and the 36" could resaw most anything up to 20" wide.? Dave
A 20¡± 1961 northfield bandsaw came up for 2k, is that a fair price? Not sure if the power feeder is included, waiting on a reply. Appears to be in good condition, new tires, 2 hp 3p.?
I will be looking to use this as a resaw at least for now, shopsawn veneers and general resaw

Re: 20¡± Northfield bandsaw
I put an Iturra spring on my Y20 as well and it is a worthwhile upgrade.? Dave

If you¡¯re interested, I bought and refurbished a Northfield 20 last fall and made a YouTube video series about the project.

I also contacted Northfield and added both the single roller resaw fence plus the regular double-sided fence. I also added the Iturra heavy spring, as the standard Northfield spring is really wimpy.? I¡¯m able to tension a ?¡± blade to 25000 psi.? The saw MIGHT
be able to handle a 1¡±, but there are some clearance issues with guides and wheel width where I wasn¡¯t sure if it was worth it, and Iturra said the difference between ?¡± and 1¡± isn¡¯t likely to be huge.
?
I haven¡¯t done a massive amount of resawing, but it¡¯s working OK. I may still have alignment issues with the single roller resaw fence; I¡¯m having arguably better results with the standard fence as long as my board is short enough that I can control it that
way.
