Table Saw Turning

I came across a 16” linear slide so I thought I’d try making a table turning fixture with it. I have bearings in the live centers but I need to add thrust bearings behind the stop collars so it spins easier. My intent was that it would turn itself as the 60T blade slaps the block but I don’t see that happening. I’m going to have to add a drive motor. Strike 1.

That is awesome. Leonard Bludworth built me one years ago that stood upright with 4 saw blades and CNC. Managed to shim the top two dead nuts, not so with bottum 2 so the bottum were used for bulk and top 2 for finish work.
 
Great concept Dan.
Why not a linear actuator so you have a lead screw in the middle ?
Add a pulley to drive the spinner ?

Something like that could make a full-on 30" taperer.
No overhang too if supported right.

I re-built a cnc taperer one time.
I used THK actuators.
I still have the long one. It's a monster THK. Got if for third of a price of a new one.

Thanks for sharing.

Wow, thats brilliant.
A great way to attach the saw and the slide.
Simple and solid, i like that.

Nice one Joey. I try not to look at things like that on Ebay, I could do some real damage to my Paypal account. I'm going back and look again, may you rot in Hell.

I actually have (2) very similar to that made by Tolomatic collecting dust. They only have 28" of travel though.

When i built my CNC inlay machine I used THK rails. If you want a direct THK replacement for only 60% of the cost, check out these guys. http://www.lintechmotion.com/

Very observant comment my friend.

That's what saw machines do and why saw machines are superior to routers for longitudinal tapering cuts on the X axis. Especially for shafts.

The push off and push on is much gentler and shocks the wood less. Very important concept for sensitive shaft wood processing. The taper is not compromised by the RMS finish. Very little sanding needed thus more consistent tapers on the cues.

Just curious, would it self rotate if the shaft was at a slight angle to the blade? Or at a more severe angle to the blade?
I'm assuming the taper is from a vertical difference end to end rather than an angle to the blade?

You want to have the fixture level as possible during the final passes by adjusting the blade elevation to match the final cut.

Dan, let us know how you re-do that short taperer.

lol Joey you could always get a loan I think that one was only like 1.2 MILLION lol but the crazy part is it paid for it self in about 5 months :grin-square: we have a new one now its a little smaller about 225x90 it was only 900K.:eek:

I miss my saw machine :sorry: it was a monster and even if you took a huge cut it always came out nice and smooth.
If I would have been working where i do now I would have kept it and just made a new taper bar out of aluminum every time I wanted a new taper. but instead I went CNC so i could have unlimited tapers.

Neat design im eager to see how this comes along.:thumbup:
