yep..from local auction. Has been a good summer for me & auctions :)
This is a portable OSS discontinued hand power tool. I was thinking of installing it in my Delta Unisaw extension wing. Long ago, I snagged one of those ‘ol dinky desktop shaper for pennies. Everything was tossed except the cast iron top. I think I can use the top for this application as a insert. Of course, modification of the cast iron top is needed. I am unsure how (even if possible) go go about it! I would like to have this tool slide into place when in use, slide back out along rabbets to remove. Just looking for ideas….

or maybe…spindle sanders do not require a table insert like router & shapers do. Hmm…. if that was a case, a simple 2” hole and a couple rabbet pieces..whalla.

void… this tool will not slide horizontally due to the spindle shaft sticking up.
time for a plan B…

1. Ask for a solution.
2.Take a popcorn sit back and relax watching how others sweat trying to bring it to you.
3.Never respond.

A lot of sweat and tears went into that picture you drew?

Since he didn’t give you the pat on the back you were hoping for, I’ll do it….

“Good job Plain, that’s a revolutionary yet simple fix to a problem. Your ingenuity is astounding and you’re a true asset to this forum.”

That better?

Sorry Plain..I have things going on (saw blade sharpening, g/f going to europe, swamp cooler issues, etc). Haven’t had time to check on replies.
Any “single” hole application will not work as this OSS has the spindle sticking up around 4-5” height for easy removal to become portable. I was researching router inserts on cabinet table saws to see how they are done but it’s like comparing apples to oranges because I would need this to to removed at times. Which lead me to building router table insert..which lead me to DIY or ProMaxRT…which lead me back to the OSS. Maybe a quick action lever lift (like in JayCreations youtube video) for this OSS…
Thanks for your time reply though. Not many have this portable machine so I’ll have to engineer something that most likely will not work but will be fun to attempt :)

But that is exactly what you need to take it out without having to slide it to the side. Loosen the bolts and turn without any lateral movements so the sicking spindle does not matter.

Plain… removing the shaft is an actual assembly. Not a solution. The sand paper drum around the spindle is easy to remove by a single bolt, but not the actual oscillating spindle.
This prevents the horizontal slide in/out. It would have to drop or raise like a router lift would. I have ideas such as I mentioned above.
If anything…this little handy tool has led me to research router stuff. Ordered my Bench Dog cast iron cabinet saw insert yesterday :)

I don’t understand why Plain’s solution won’t work. The downside is you permanently have the circle doodad attached to your OSS but that wasn’t your objection. Maybe you misunderstood how it works?

Simpler solution is use metal clips to hold the OSS in place. Look up jig saws mounted upside down in tables, that’s similar to this.
