I reviewed this product previously at the following link. ?Perhaps this would help you understand its function and if it fits the t-slot of the Hammer slider. ?The Kappa 550 version is longer and has different slot positions because the sliding table on that machine is wider and has two t-slots.

Someone on this group surely knows better than i do, but it comes in two variants… one for Kappa machines, and one for X-Roll machines, which I believe are fitted on some hammer models.

I have a full mortising setup for the AD741, a full mobility carriage w/bar, the outrigger transport thingie, and felder's fritz and Franz - the sawing and clamping jig.
All of these items are new in boxes.
?
I am located in the south San Francisco Bay Area.
?
I would sell any of these items at 60% of the current sale prices. No idea how to handle the shipping of some of the larger pieces however. ?Any suggestions would be appreciated!
I have found that 3 points of fixing of the short cross cut fence provides perfect stability, even when heavy tenoning on the spindle moulder.? And even with Felder's "sloppy" work.
Here I show my short fence afixed to 4"x2"x1/4" aluminium angle and bolted to the slider at 3 points.
The short fence used for tenoning on the moulder is mounted to 70mm x 30mm x 20mm aluminium plate and this too is afixed at 3 points to the slider.? The plate is drilled and tapped to take air clamps.
And for parallel cutting, I use neither fixed fence but x2 parallel fences, which I would not be without.
The detailed drawings are not well organized or presented, and is missing some information . I recently was checking that I could actually get my new Kappa 450X into my shop, and had to contact Felder to get the missing information. I am fairly certain that some of the information they gave me is incorrect.

These ideas will work for lay out ideas. While a proper 3d model would make it over the top for space and work flow guess it is not really needed.
Maybe someday Felder will release models for this purpose. We don't need the super detailed info that they have. Just the basic dimension and slide movement for sliders.

I couldn't spend too much time on properly appealing modelling and geometries in Fusion, so I used some generic simple extrusion geometries? to the nearest couple inches tolerance, but made sure my working "bench" heights were proper so I could share machine tables where they needed to be coplanar, or make sure one surface was high enough to clear obstacles. For example, the?frame clamping press isn't fully defined except with a taper extrusion?for the angle as it sits. The slider saw has a big block where the carriage and cross fence need clearance. Anyways, I made each machine its own file for future sophistications as needed, then inserted them into the main shop file. If I want to add machines later or trade out, it's not cumbersome and keeps the main file from getting too complex. This iteration is from 2021.
A neat feature of modeling this way is the ability to make 2x4 sticks and 4x8 sheets and move them about to test fit.
At this point my shop has reconfigured nearly every year, it's always a work in progress.

David:
I have been on the same journey and looked everywhere for models. Finally, I got the dimensional drawings of most of the equipment I have, along with the equipment I will order. Then I drew the footprint of my shop building in Fusion (you can do in Sketchup too) and drew the outlines of each of the machines; pallet racks, etc. and extruded them to roughly their heights. While they are not true representations of the machines, etc., they are proportionally accurate representations in terms of size. I created each extruded cube as a separate body and labeled each one so I can move them around and determine accurate clearances, workflows, etc.? Not as pretty has having accurate models of my actual equipment, but I was more concerned in how to organize it efficiently to optimize placement in my shop.
?
Here is a link to my shop model in Fusion:
?
Attached is a screenshot w/the floorplan, machines in position, and the "naming tree" identifying the equipment.?
I hope this is helpful.

You guys are kidding yourself. ?+/-1.0 mm would be more sloppy than the original Felder unit. ?The required spec is +/- 0.01mm or better. ?What I produced was +/-0.0003-inches or +/- 0.008mm otherwise I scrapped them - a lot of them. ?The narrow distance between the pivot point and the point of 90° registration is woefully inadequate and a flawed design IMO. I did the best I could to work with the existing design and the tolerances is required with the existing Felder design are extreme. ?And like I said before, there’s more to this than machining T-nut and mating bushing. ?
If you really want to put energy into finding a solution here I suggest you focus on a new design that uses the P-channel (angled top prism feature) for registration with two points of contact via mating saddles to provide the 90° registration - similar to how the outrigger table attaches to the slider. ?If you want something that does angled miters a new approach similar to the following is the right strategy, or use the EGL/DGL. ?

Hi Nate,
David be the best to tell us if it is worthwhile to relax the 1/2 mil spec (between the bushing and the counterbore in t-nut), which is hard to meet. I would be worthwhile to know the effect on accuracy if the bushing OD tolerance is changed to +0/-1 mil. Which I hope more machine shops can meet.

Are we familiar with any metal show that is willing to produce something with a tolerance of 0.01mm?
If it is the same motor as my Hammer J/P, it should be 4HP and 3KW. A 20A breaker should be sufficient (Felder told me I can use either 20 or 30A breaker)
Yes, it is single phase. I don't know the size of the motor. I assume (perhaps erroneously) that the 531s all came with the same size motor. (Unfortunately, the unit itself is in storage and I won't be able to access it for a bit.)
