Zero Clearance Inserts for Hammer K-3
开云体育Hey gang...I’m new to the forum, but thought I’d share my ZCI’s. As you all know, most sliding table saws have much to be desired when it comes to the saw blade insert. Small off-cuts are constantly getting jammed or flung across the shop! There is simply too much space around the blade, or even with other zero clearance inserts, once the blade plunges through it, there is only a small amount of insert material remaining to the left of the blade. Weak!?Mine are superb!?
These quality ZCI’s will minimize tear out, eliminate small off-cuts from getting wedged, and make cutting on your Hammer K-3 so much safer!??Made of Baltic Birch and covered on both sides with high pressure laminate (Formica) that is adhered with epoxy (rather than contact cement)...this creates a smooth, strong and very rigid insert.
I’ve shipped over 70 of these with hugely positive feedback. So far these fit:?
Hammer K-3 Felder CF-531 Hammer C3 31 Felder K500P and K500S (please check! The length of mine are 22 13/16” or 579 mm)?
The first link/video (scroll down to see video) shows the inserts in action...the second link is a vid that shows an easy and safe way to elongate the saw kerf to accommodate the riving knife. ?And how I cut the slot for the scoring blade. ?Thanks a ton, Ramon

I can vouch for Ramon.. he's the real deal and a great guy.. posts really great woodworking tips and tricks and stuff on Instagram

I have not found one for my K975.. they are a bit complicated to make and Ramon does not make one for our saw..I really wished someone would though..I'd buy it in a heartbeat

I have the same question as Imran Randy. I’d love to have a zci for my saw Bill Belanger? On Tue, Jul 28, 2020 at 23:00 imranindiana via <imranindiana=[email protected]> wrote:

you have a Kappa 400 right Bill?

开云体育Didn’t I see a video where David B made one for his saw? Not sure which one but it was the 3 piece which I think is on the 900 series and the Kappa although not sure if they are all the same geometry.David? Poke,poke...

If I remember correctly, the space between the blade and cast iron top was larger on my K915 than the Kappa... Bill Belanger? On Wed, Jul 29, 2020 at 8:04 AM Randy Child via <strongman_one=[email protected]> wrote:

开云体育I make Zero-Clearance throat plate kits that fit the Kappa 40 and Kappa 400. ? DM me if interested (david @ bestservices . biz). ? Details are here including a dimensioned drawing if you want to attempt making your own - it isn’t simple: ??I owned a K975 for 10 years and pondered making ZCI’s for it several times, but it is very complex because of the trunion components that attach to the side of the cast iron top. ? So I never attempted a ZCI for the K975. David Best https://www.instagram.com/davidpbest/

I bought a pair of these back in early June, which means I didn't get the extra screws noted in the video.? That's no big deal though.? I used a 1/8" brad point bit followed by a 1/8" router bit (on a router table) to extend my insert for the riving knife.? I might have to extend it a little further though, as there's barely any room to install the riving knife when dealing with a 12" blade.? I haven't had the need to run with my scoring blade lately, so that section is still covered.
I've installed one insert so far, and the only problem I had was that I had to remove a tiny section on the underside near the front in order to get it to fit properly.? It wouldn't seat correctly otherwise as it was pushing against the little bits they have there on the K3.? That was easily done with a beater chisel.? I haven't looked at the other insert to see if it has the same problem. Separately, I found that I can only remove or install the insert with the sliding table pushed all the way to the rear.? This of course is the opposite of where you put the table when changing the blade.? So if I'm switching out the blade for a dado or for a home-made 45 degree insert then I have to move the table back and forth to go between dealing with the blade and the insert.? That's not the fault of the insert; it's due to the tightness of the space there coupled with the extra "meat" of the insert.? But it's a small inconvenience and easily overlooked thanks to the size and strength of the insert.? I've already broken the little sliver to the left of the blade off an OEM insert; I'll stick with Ramon's inserts from now on. |
Hey Steve
I'm glad you figured out how to cut and extend the saw kerf...your way is a good solution. ?The reason I didn't cut saw kerfs to begin with is because...after talking with a Felder/Hammer rep, he suggested NOT to cut the kerfs. ?He stated that they can be in slightly different locations latterly (or left & right). ?Factory ZCI's are never sold with a saw blade kerf. ? So, that's when I decided to make the "how to" video that shows how I safely created the kerf on mine and started supplying the two wood screws.? It's interesting that your slider part has to be rearward to install the insert. ?Mine must be forward...so this tells me that there are some slight differences with the machines. ?As far as the fitment of the insert, I only had one other report (besides yours) related to that slight adjustment that needed to be made for proper fitment. ?I've since adjusted my jigs to make the accommodations. ?Strange thing is...the inserts fit my K-3 with or without that modification. ? ?And yes, the tiny 4mm sliver that is created to the left of the factory ZCI and their regular insert is weak. ?Mine broke after only two days! ?I knew there had to be a better way. ?I'm super pleased with my version. ?Especially when cutting small parts. ? Anyway, thanks a ton for your support! ?Ramon |
Felder must have changed their inserts from the fine ply phenolic. I've got 3 and never had an issue with them. Scoring pretty well eliminates their use on the slider because of the table slider height difference and I don't work from the fence side so of?no use to me. No matter how tight to the blade is too the?insert there is always cutoffs that will jamb and create issues. I've got 2 nicks in my slider because of extreme blade deflection cause?by ZCI. The howling?from the balde they can create is another issue. Sorry for the negative comments about ZCI but reality is such.

开云体育John, Don’t understand your comment that a zci won’t work with scoring, maybe I am misunderstanding your comment but I have no issues with my 20min Prototype build of one, I also have no howling like you describe. I could see the potential for the jamming like you describe but haven’t had that yet and kickback from small cutoffs is gone Regards, Mark On Jul 30, 2020, at 11:22 AM, jmkserv@... wrote:

开云体育I didn't say that it doesn't work I said it not needed with scoring. I had a nice one like you are showing until it got blown to rat shit with a tapered cutoff. Now I use this when necessary. But as always whatever works for you, my experience dictates otherwise. The other inserts are 10 years old and only used for support when doing dados. No blowouts on the thin material but dados really don't create that issue.?
