Re: sliding table saw: parallel fence vs 2nd crosscut fence?
#k700s
¿ªÔÆÌåÓý
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.

Re: 3d models for shop layout
Kerry, Brett
?
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. |

Re: 3d models for shop layout
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. On Fri, Oct 18, 2024 at 1:29?PM Kerryj_smith via <kerry=[email protected]> wrote:

Re: sliding table saw: parallel fence vs 2nd crosscut fence?

¿ªÔÆÌåÓýHi 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.

¿ªÔÆÌåÓýHi Chris, Well I shared this on my FB page and there is interest for 16 pieces. Probably not enough but anyone willing to take up this project? Imran Malik On Oct 11, 2024, at 8:14?AM, chris connolly via groups.io <connollyack@...> wrote:
?Thanks David, beautiful work. My short crosscut fence is always going on and off my k700 and i¡¯m tired of having to fine tune it for square each time. I also notice that the fence gets pulled forward and away from the flip up stop slightly when tightening the outboard kip lever, but that is more controllable.? I would love to have your upgraded attachment design on my saw but I realize you aren¡¯t interested in fabricating more of these. Does anyone have any thoughts on the feasibility of getting a significant order together and hiring a machine shop to fabricate some of these? Chris Connolly?

? A first post with a simple question: How large an electrical circuit is required for this machine?

I should soon take possession and want to know if I need to add another circuit in my shop. My SawStop and 18" bandsaw share a 20A/240V circuit (only one machine runs at a time, of course). Will this 20A circuit be adequate for the AD 531 as well, or should I plan on a 30A circuit?

I tried calling Felder service, but their line hangs up after telling me my call will be answered in the order received.?

I appreciate any thoughts.

Many thanks,

Re: 3d models for shop layout
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.
