Why Pivot the Way Tubes Both Ways

[SDSSmith]

...
Reverse sanding - not sure?

With the grain cuts - Not a clue!

Think it might have to do with turning, lathe work......

While trying not to be a nag, can we return to the original question, please.

Why do we (Mark V Users) want to be able to pivot the Way Tubes both ways (from the left and from the right).

Pivoting on the users left is what will be the new configuration and I can see that this places the drive shaft on top of the headstock. Now it could be used as an under the table router/shaper but only if something is done to the table set up. Has anyone heard that this is in the works?

Furthermore as I said before, I am NOT KEEN on sacrificing table saw time to the router tasks. Doing so would radically increase the number of change overs (at least for me).

What other reasons make me want to pivot on the left?

If I am not going to configure for routing and shaping, are there any other reasons why I might want to run in reverse?

Methinks the deafening silence re your question(is that all) is your answer!

I cannot think of any other advantage to the double tilt 'feature'.

Regarding the table tilting, SOMETHING has to change to accomplish the under table/left tilt objective. The original Mark VII had a 180 degree trunion range. Either the trunion is redesigned, or as has been 'suggested' the rack has been duplicated on the back side. My prognostication is the trunion redesign.

From slightly out from the main trunk of this threads tree, that reverse sanding 'feature' that apparently appeals to lathe folks.

Sorry I could not come up with any further 'justification'!;)

I'm just a bit concerned about unintended consequences. If the unit lifts from either end I think I would not be able to keep my bandsaw mounted on the left. It remains there almost all the time and is used often. Also without the lift-assist I would have a difficult time reconfiguring my SS.
Just my two cents.

JPG, Creating a rack on the opposite side of the vertical would allow the table to be mounted at 180° from normal but that won't work. The table, with respect to the trunnions is not symmetric.

kalynzoo, I have spent considerable time staring at and comparing the Base Arm (24) and the Headrest (13) along with all the associated hardware and I do not believe there will be a problem there. I wish I had a Base Arm...I would install it instead of the Headrest just to see. I am much like you in that I have an SPT resident on the Mark V almost constantly. For me it is the jointer.

SDSSmith and nuhobby, I can see that being reversible is great for sanding some items. I do that some using the Crafters Station (my main sanding station as well).

If these are the only reasons for a dual pivot configuration, all I can say is that it would be a cool feature in a new unit but I am not yet convinced that I would pay much to upgrade.

Now, it would be a really nice gesture if Shopsmith would just throw that in (in exchange of course) when someone buys a new PowerPro or Power Pro Upgrade.:):)

Having the ability to bring the quill and cutter up from below the reference surface is an advantage. With the Shopsmith in it's normal (tilted right/table tilted left) vertical position the machine is kind of like the over arm router (cutter comes from above the reference surface). With the Shopsmith in it's new Abby Normal (tilted left/table tilted right) vertical position it would be like a normal router table with the cutter coming from below the reference surface. As far as the table goes, I would prefer that it tilts 90 degrees each way as opposed to having to pull the table and reverse it. As far as tool storage goes, an upgrade to the headrest will yield the old headrest to store your tool.

I do not think 'storage' is their issue, taking/putting it off/on is! Especially the jointer. Sure would be nice to see a 'lift assist' for that operation!:D

Yes I HAVE seen the hoist solution!;)

Dusty, I think that your logic is on course and quite frankly I personally would not pay extra for that feature. As you say, "cool feature" but as we are always saying, everybody works differently and have different needs / wants. That feature means even less to me since I already have some Mark VII's and when I do eventually order a PowerPro headstock or conversion I might try it on both a Mark V (my 510) and a Mark VII. I do like a shaper function.
-
On the old Mark VII (and I suspect the new one as well) you can release the latches at both ends and just lift the complete upper assembly (upper and lower tubes are both attached to solidly mounted ends at both ends kind of like a big rigid box on the old one) and sit it aside on the floor or a table or saw horses. It has been crossing my mind lately to either attach that assembly vertically to a wall, post or custom designed base in the position where the headstock is under the table as a dedicated shaper. I can gain the cutter speed needed by just removing the upper belt and replacing it with a belt drive on a set of external pulleys of the proper size combination mounted on the two stub shafts. Perhaps even a set of cone pulleys.
-
I am afraid that I can't give you any really compelling reasons why you would want to add the cost of the whole unit to your shop...
I guess at this point you are stuck with it all just being cool and maybe "wanted".

If I was ten(10) years younger I might not be thinking this way. But I am 71 and believe that I can count on maybe ten(10) more years in the shop. I need to sorta feel like I can get my monies worth in that remaining time.

The kids and grand kids are already spoiled rotten. It is time for them to learn to deal with a few used items. Given the state of the economy, I think they are going to get their chances.

Dusty;
I am with you on your last post!! I just joked with my kids as to changing my trust book so they would not fight over the power pro headstock when I kick off. I am ready to turn 70 this month and I am planning on twenty years more anyhow.

Well, what do you know. I was just doing a drill-press job with my Shopsmith 510. I wanted my 2 opposing holes each 22.5 degrees away from perpendicular to the (somewhat wide) board. I got by with some flipping and extending and such, but if I had a 180-degree trunnion I would have been happier....
