Re: Replacement of internal dust hose is K3 Hammer slider
As for the hose, I have shared this before. This is a flexible (expands and contracts easily) hose and does not put as much strain on the plastic transitional piece (that it attaches to) on my K975.
I have had it since 2020 with no issues.

Hello Imran, sorry for the delayed response, my girlfriend had a car accident and I had to focus on that for the last little while.?
I¡¯ll try a different approach with the schematic, I¡¯ve scanned as a pdf and I¡¯ll attach that, hopefully that¡¯ll fix the resolution issues. I feel it¡¯s an important piece of information.
I do believe those two black upper wires are the primary legs, however reviewing the schematic has me confused.. 1F2 (primary leg) and 1F3 (secondary load) are spec¡¯d for a 400ma fuse, 1F4 (the other primary leg on the diagram) is spec¡¯d for a 2 amp fuse. On my transformer all 3 of the upper fuse connections are 400ma, and the lower one connected to the red wire is 2 amp. I know that I put the fuses back right where I found them when i was inspecting them. Not sure if they were put in wrong before I got the machine, the seal was broken so someone has been in the electrical box before me. Or perhaps the red wire is the second primary? Doesn¡¯t line up with the diagram on top of the transformer though. Either way, results of the continuity test have no continuity from the top black wires to ground.. and the red wires do have continuity to ground, but that seems intentional as they¡¯re bridged at the bus bar to ground by a jumped wire, looks like from the factory.?
Not sure if you caught it in one of my previous messages, but I noticed the thermal overload relay (1F1) wasn¡¯t functioning at all when trying to trigger the test switch, and the reset button has no feedback. So I¡¯ve ordered a replacement for that anyways, should be here in a few days. Do you reckon that could be part of the issue??
Thank you for your help so far,
Andrew

Actually, I¡¯ve been doing some test prints with carbon fiber reinforced PETG and Nylon recently, and I¡¯ve been really impressed how well it compares to aluminum in some applications. ? This stuff in particular has really impressed me: ?
https://www.amazon.com/dp/B0BDFBPDKP?ref=ppx_yo2ov_dt_b_product_details&th=1
This stuff is even stronger, but it is 4X the price and requires well regulated high temp enclosure (which I have but I don¡¯t like the off-gas in my office):
https://www.prusa3d.com/en/product/prusament-pa11-carbon-fiber-black-800g/ Over the weekend I¡¯ll print up my bridge clamp design in that PETG-CF and give it an AB test with Cocobolo using Mac¡¯s clamps at 150 PSI. ? ? Some background on what started me down this path is here:

Re: Replacement of internal dust hose is K3 Hammer slider
Chris and Imran, my measurement is that the bottom edge of the port/dust chute on my K3 is 1" from the cabinet wall when the trunnion is angled to full 45 degree tilt.? I got that my measuring down the tilted port to the, subtracting the length of the port and converting the 1.5" hypotenuse to the horizontal distance.??
The bottom edge of my port has protruding flat tabs on either end and protruding pin 1/2" up on the left (blade slot) side.? That allows the use of the 1/2" hose clamp in the original setup.? If the pin were cut or filed off, a wider band could perhaps be used.? You can see the pin in the photo attached.

Re: Replacement of internal dust hose is K3 Hammer slider
I have had to recently replace my internal hose due to original disintegrating also, I was surprised to hear felder didnt have this kind of fitting like yours at the printables url you provided.? Thanks for this thread id very much like to try out that model on my saw. It was an absolute pain to try and adapt the 100mm hose around that rectangle, had to cut the wire in a couple areas for it to fit.
Ill get this model printed and also fit my zero clearance insert to see how that improves collection.
Thanks, Nathan

Imran - your schematic, # 25, is exactly the kind of transition I was thinking of. Not sure if that would clear the side wall ( when saw blade is tilted to 45) in the Hammer K3 and C3-31 machines, but it looks promising.?
Thanks for sharing.
I have been wondering if a pivoting rectangular to round adapter could be configured? So that as the saw blade is tilted to 45 degrees, the adapter swings down so the round connector for the hose is always pointing downward.
I'd been thinking along similar lines. Option 1 being to adapt from rectangular to circular, with the port on the side (as per Imran's drawing), and then running the hose to a new port on the machine's side. Option 2 being an adapter with a pivoting section in the way that you describe. I suspect the problem with both would be more tendency clog, but option 1 gives lots of scope for a big "plenum", perhaps with a door for clearing it. In the short term I made an adapter out of scrap plywood and a section of plastic pipe that I softened and reshaped with a heat gun - it looks cr*p but has worked for quite a while, although it sometimes falls off on the rare times I have to go to 45 degrees.
