James - I also noticed two washer stacks - was there some major sagging??

Paddle Switch for felder tools
#diy
I created this DIY paddle switch for the table saw several years ago and have found it very helpful. ?If this hasn't already been suggested, (couldn't find anything in the search) thought it might help others that also have the start/stop on the machine base.
best,? Anthony? |

¿ªÔÆÌåÓýSang Luu, very nice looking solution. Grizzly guard indeed looks just as good as any. As Mark said you do want to consider getting it out of the way. swinging is likely not an easy option for this design but the single horizontal member could be done with two that slide against each other. Maybe the guard is easy to remove and that is the solution you already have on hand. imran On Jul 15, 2020, at 3:24 PM, Sang Luu <sangluu@...> wrote:

It uses 1530 profile and attaches directly to the K700s mounting points and extends out enough to cut a 8' sheet at exactly 48". 1530 profiles have a decent deflection rating at the lengths required for the arm, so I chose them rather than the larger 3030 which would have weighed a lot more. There's some additional reinforcement using 80/20's 45 degree brackets and plates. Going with 80/20 made it easier to put together without the prep, and finish work needed with welded steel but with a bit of added cost.? There are several plates/brackets that will connect the Grizzly assemblies to the profile and for kicks, I've decided to add a simple linear actuator to raise/lower the head. There are other ways to do this using gas springs but decided the actuator was the simplest approach for me. The brackets ride on 80/20 linear bearings to allow for the movement.?

James - I suspect that pivot is very well made, with a beefy bearing. I'm trying to avoid as much custom machining as possible, but it might be unavoidable for this type of design. Thanks for sharing, will keep for reference.?

This is how the horizontal square?steel tube is secured on my 2016 KF700, very rigid.?It can be swung out to the right when using the shaper. The steel tube Felder uses is heavy duty, may not necessary.? James On Wed, Jul 15, 2020 at 4:18 PM Sang Luu <sangluu@...> wrote: I haven't decided on how best to implement a pivot.

The parts for the guard from Grizzly are:? P0764Z2034? ? ? DUST HOOD ASSY P0764Z2035? ? ? BLADE GUARD ASSY (WIDE) P0764Z2036? ? ? BLADE GUARD ASSY (NARROW) They came in at a reasonable $342.17 shipped -- but in hindsight I could have just ordered the narrow with only the wide poly carb window - I don't think it's necessary to have both, just more convenient.? |

¿ªÔÆÌåÓýNice job. ? Personally, I would not want an overhead guard that did not have the ability to swing out of the way, along with a quick release at the guard end. ????What did Grizzly charge you for the guard assembly? David Best https://www.instagram.com/davidpbest/

¿ªÔÆÌåÓýNice job Sang! Question can you swing it out of the way? I actually do that quite often for the clamps to clear on narrow parts or for odd ball tall stuff like the attached picRegards, Mark On Jul 15, 2020, at 3:24 PM, Sang Luu <sangluu@...> wrote:

Re: Need a new bandsaw
I used to have that saw as well. Mine was a lemon though. Had an erratic blade jumping problem we could never completely eliminate. When it worked it cut very well. Tempted to try another.
