does anyone see any problems with that?
also on a general note.
why does SS have different type of hubs. One 5 groove for the SPT and the other 4 groove for the the headstock.
please don't say to fit their coupler, because in looking at it, the coupler doesn't have to have a 5/4 groove if the headstock/spt didn't.
inquiring minds want to know.
Personally from a safety standpoint, I would not drive the bandsaw and sander at the same time. That said a concern with welding the hubs together relates to misalignment of the shafts. If the shafts are misaligned and you connect them with a solid coupling (welded hubs) you may experience some vibrbrbrbrbrbration.]

I saw over on the Yahoo group a post by someone saying they had mounted a dado arbor on the tool and then added a hub to it and then the coupler.

I am not planning on ever running both at the same time, especially for the seconds to slide the headstock over, not worth the risk.
I think the points of the vibrbrbrbrbrbration ;-) make sense and as suggested earlier, I'll try the hose idea. Should work.
Thanks for the insight of why a coupler and 5/4 groove.
Dusty I want to mount my belt sander also.
With the spider couplings---is there a little give so there isn't that possibility of welded metal to metal misalignment?

There is a rubber like insert that fits between the 2 halfs that really dampens any vibration when aligned. You still want to align the half couplers as best you can. I use these Love Joy couplers for many of my fun projects as they do not break like the Shopsmith plastic couplers when slightly misaligned. Plus you can get the ID of either coupler in many different sizes which used the same insert.
problem solved

Haven't gotten around getting the love joy and star washer yet.
A rigid coupler was too much vibration as suggested.
Couldn't easy find a rubber hose size.
So I cut up a SS coupler, used one side for each tool. Used the correct hub, one accessory style for one tool, one headstock for the other.
Put in taller allen screws to prevent movement of the coupler. There is enough grab of the coupler to run both tools. These tools do run at the lower speed so that good. There is enough space so when I slide the headstock from one tool to another there is a space so both tools don't run at the same time.

Interesting innovation. Curious how it will 'hold up'. I would still check out the lovejoy couplers. Another 'choice' is the OLD 10E/ER jig saw coupler.

I thought that regular garden hose was either 1/2" or 5/8" ID.

My guess would be he couldn't find a short 'piece'.

no, don't you guys know thicker is better
I was looking for a ID that would fit over the hubs. I thought it would be more secure than over the shaft which is beveled flat for the allen screw.
also I was looking for a woven type hose for more strength.

Hoses that are used on washing machines and dish washers are high strength and should withstand the torque nicely. The supply line on my dishwasher even has a metal brade around it. Maybe you could find a used one at an appliance store that sells washers. Good luck Lee
