Plunge Cutting on a TS


Coop

Recommended Posts

I asked this of Kev via pm but should have posted it here if anyone was interested and could receive benefit. Question was, is it safe to plunge cut a groove into the edge of a board on the ts to receive a panel. I thought it risky and took the slow route, using the router table, a little bit at a time. Has anyone taken the ts route?

Should have included Kev’s response in that he thought the same. 

Leave it out for now..  I'm interested in the unbiased responses as well..  

I have no issues with anyone knowing my response either.

Just a single pass with the TS?  You mean the face edge of a board and not the end grain edge, right?

As an anecdote; the very first cut I made with my TS, an angle cut on the Modified Ship's Ladder stringer, I approached the cut after plunging and the damn thing jumped out of the cut and nearly off the table and I was sure I had damaged either the guide rail or the saw or both.

I damaged neither.  But, from that time to now I make sure the TS is more FIRMLY in hand (I slowly plunge to depth) and the Kick-Back accessory is in place!

I'll help where I can.

Regards,

The cut I am referring to would be a groove along the edge of a board (stiles) to capture a panel. The rails and stiles are joined by dominos and I didn’t want the groove to extend the length of the stile so it would be a stopped groove, ending prior to the first Domino. A plunge cut, similar to what you would do with a router. Hope that makes sense?

Another down side to performing this operation at the TS is the fact that your ends would need a lot of hand work to clean up and get flat.

The safety factor alone would make this a pure NO GO for me!

That is a difficult cut to make with any hand-held tool.  Especially making multiple passes with a circular saw of any sort.  My Thought Process Machine instantly envisions disaster, to the material and/or the material handler! 😲

You've a dangerous mind, brother! 😉 😆

I can't think of any process that would make me want to plunge cut on a TS, it just seems like a process that would do nothing but create an open opportunity for a kick back.  My choices, in order of preference, would be hand held router with my two fences, plunge on the router table or a rabbet and then a fill strip on  the inside like you did with your bathroom door project.

I have done it but the last time it cost me the tip of my finger. Use a Festool plunge saw (I thought of this while getting stitched up in the emergency room 🤦‍♂️) or a router not worth the risk. Fwiw I was making custom grates for my office desk to vent the computer cabinet.

I ended up doing it on the router table. The only reason for asking is that I had 4 ea. 6’ pieces and wondered if there was a faster way to do it safely and the groove was only 3/8” deep.

They are plunge saws, respectfully.

Plunge cuts can be made more safely with one (or two) of these...

The *(or two)* was in referencing using 2 of them as stops.  You can make a stopped groove with 2 of Kickback Stops.

I'm just not sold on doing that on the edge of a board. 🤪 😁
