Re: Hammer saw height adjustment seizing

 

I'm thinking from memory the tight spot on the Hammer K3's is the brass block # 88 and the shaft # 91. It is located right in the front of the opening in the saw showing the angle of cut. The block can be seen easily and lubricated right there with a fine oil ( not sure of the best one though)
Re: blade compatibility

 

Does your saw table have these three holes bored through it which are a requirement for the scoring blade?
Re: Hammer saw height adjustment seizing

Bram,

My C3-31 was delivered in 2017. Over the years, a number of FOG members have posted about lubrication of the saw elevation mechanism. Not too long ago, one of the posts mentioned the brass block as part of the issue. Before that post, I had not recognized the importance of the brass block.

After reading that post, and adding lubricant to the threads behind the brass block, the mechanism for elevating the blade has functioned more smoothly. In the environment of my shop, this must be done about once a month.

With the sliding table pushed to the back of the saw, and the blade tilted to something over 30 degrees, the brass block can be seen just below the threaded rod that is part of the tilting mechanism. From this angle, it is possible to apply lubricant to the threads just to the rear of the brass block.

Hopefully, more experienced members of the forum will let us know if this is a reasonable approach, or if there is a better way to lubricate the elevation mechanism.

Hi,

Lately I've been experiencing issues with adjusting the height of the saw on a C3-31. It is becoming really difficult to raise up and it makes and feels like metal parts rubbing on each other without lubrication (seizing). I've already completely opened up the saw and cleared any dust from the moving surfaces and lubricating them with dry lube. It did make it slightly better but didn't fix the issue. My current idea is that something is wrong in the brass block indicated in the picture below. I haven't been able to get either the shaft or the block free from the machine to try and spin it "without load" as that would be a real undertaking.

Did anybody experience something similar and if so how did you fix it?

Re: Hammer saw height adjustment seizing

 

Hi,

Completely opening up is perhaps overstated. I removed the blade, the dust catcher (#7 in the attached drawing) and the sliding panel to get access to the insides. If you then move the sliding table back and forth and twist your arm a bit you can get to most parts. Tilting the blade 45¡ã gives you nice access to the shaft and suspected block, through the holes of the angle gauge en height adjustment wheel.?

What parts/surfaces did you then lubricate with the Supergleit? Cause like you I am a bit skeptical about it :)

Brian,

To what surface did you apply the Supergleit? How did you access the proper surface?

Thanks,
Steve

I had the same issue and same results until I used the expensive Supergleit from Felder. I was skeptical about that product until I tried it, but I've had no issue raising the blade after using it.

Re: blade compatibility

 

Hi Nathan -
- I purchased the C3-31 with the scoring blade, so I have never tried to disassemble the scoring unit.? To Imran's point, when I rotate the saw blade, the scoring unit counter-rotates, it may well be same belt driven.
- The Felder grooving cutter and the Forrest dado king are both good, like both, use both.? (I realize that does not answer your question).
- I got the Forrest DK because the Felder grooving cutter minimum width is 8mm.? For nominal 1/4" (6.1mm) Baltic Birch ply, I was looking for a dedicated 6mm grooving blade.?
- Turns out the Dado King was not much more in cost, so I just got the DK instead.? It cuts beautifully, does dados for the 1/4 ply really well.? For larger dados/rebates I use the Felder grooving cutter.
- Note that the Hammer is restricted to 180mm max on grooving/dado cutters.
? ? ? ?? good luck w your decision, cheers...

Nathan,

The FB instance of someone installing a scoring unit in field was on a 2018 CF741 - link below. This was a independent scorer vs one driven by the belt from saw motor.?I do not know if same is true for Hammer.?

Re: A3-31 setup and calibration

 

Hi Richard?

I first tighten them by hand about 5 degrees out (higher) w.r.t. where I want them to finish. After that I tighten them with a normal size wrench to a moderate force.?

I determined the amount I put them too high before tighting by obsering the rotation while tighting. So i guess it is a balancing act.

Note that these definetly don't need that much force as they are a pretty large thread size with near to no lateral or rotational forces on them.

Just when I thought I was done, I find myself struggling to get this right. I seem to get things aligned within .003-.005¡± between the infeed and outfeed tables. So I¡¯ll joint something then plane it, and when I return the infeed and outfeed tables down, one of them is sitting lower. It is very clearly the bolts at the front that are too low, but it is inconsistent between infeed and outfeed and they seem to be fine before I raise the tables for planing.

is this just a case of not tightening the nuts sufficiently? I try not to lay into them too much because that tends to throw things out of alignment as well.

If the machine is a Felder 700 series or higher, then push the sliding able all the way forward. ?That will give you maximum access to the scoring saw.

blade compatibility

 

I was hoping someone can help me verify dimensions of my C3 31 combo. I¡¯m looking for the arbor length needed to run the dado blade from Felder. ?Then also what makes a saw compatible or not for the scriber blade assembly?

From Felder I have been told the scriber blade isn¡¯t something you can add after purchase but I don¡¯t know what specifically prevents the compatibility as I have read in the Facebook Felder group that other members have bought the assembly and fitted it themselves


I was hoping to measure my arbor length to compare to someone so I know once and for all if mine can run it and same goes for scriber blade before I place the order with Felder.?


Thanks in advance

Re: New solution to adapt 140mm port to 6¡± flex hose

 

Not a hose solution but I purchased a large roll of floor matting, unused,? at a flea market, the kind that is used in trucks that haul cattle. It's about 1 inch thick indestructable very comfortable to stand on. Works really well in front of benches and tools. bought a long time ago maybe 20 years, still have plenty left.

New solution to adapt 140mm port to 6¡± flex hose

 

¿ªÔÆÌåÓý

?I have been rebuilding the Langzauner edge sander that was badly damaged in shipping a couple years ago. Detailed post to come later. Anyway here is the simple way I adapted the metric dust port to 6¡± flex.
I bought a roll of black rubber floor pad from Home Depot??to use as tool mats on top of tool chests. The mat is about 6mm thick. I cut a 2¡± wide strip and glued it to the port on the machine. The end size is slightly under 6¡±, just enough for the flex hose to easily slip on. $48 for the mat would be a bit much for this use only but it¡¯s awesome on to of tool boxes. I¡¯ve also used it for anti vibration pads.
