Wheeee… here I go displaying my ignorance yet again!
I am new to “doing” WW but I’ve been fantasizing about it and I’ve been studying it for a while. I am jumping into “child rocker manufacturing” because the opportunity fell into my lap and it seemed like a good way to jump start my career change at age 60. I bought pre-cut parts for 375 rockers from the estate of a retired and recently deceased owner of a furniture factory. But, of course, I stumble repeatedly, finding I cannot figure out how to do something that I am quite sure must be pretty easy. The subject of this post is an example… I have rougly 2,000 wood pieces (shown below) that have the round tenon circumference pre-cut but the shoulders remain uncut. That’s 4,000 shoulders to cut. So I want to be efficient. Since they must have been ordered pre-cut this way, there must be a reason. And there must be a way to easily cut the shoulders. But it sure baffles me!
- Note there are two types of stock –
- one is square stock
- one is rectangular stock (the round tenons are the same size)
- the depth of cut required varies too much to simply rotate the piece over a table saw pushing against a shop block…
- unless I make a jig that uses the tenon as a pivot, suspending it over the saw blade [that seems doable but too complicated – like there must be a simpler answer]
Any suggestions? Thanks! View Image View Image View Image

Hi,
If I had to cut the shoulders of this many tenons, I'd build a router jig that did one thing only.....rotating this over a table saw blade sounds scary at best.
I'd build a router jig with a plunge router and 1/2" or so spiral cutter and, perhaps a guide bearing that would accept the tenon end of the stock...like the Leigh M&T jig....that would let me trim the un-cut portion of the shoulders but not cut into the tenon. I'd set the router up and leave it in place until all were cut...use a good bit and not to do too many changeovers.
Good luck!

I might think about inserting the stock into a length of PVC pipe leaving the end protruding. This should work to center the tenon for both square and rectangular parts (different pipe diameters required of course). Next, I would go to the bandsaw. I'd use a v-block to support the pipe and allow the workpiece to be rotated against the blade. I'd clamp a stop block to the table perpendicular to the blade to set the depth of cut and I'd use the fence to set the distance of the cut from the end of the workpiece. Then I'd slowly feed the workpiece and v-block into the blade until it hit the stop block and rotate the piece to cut the shoulder.
Good luck, Mike
