Why Pivot the Way Tubes Both Ways

dusty · Post by **dusty** » Thu Jul 08, 2010 7:49 pm

I recognize that there is a lot of excitement over the new headstock with its increased power and speed and all but I am a bit uncertain as to why there is so much interest in being able to pivot at both ends.

I recognize that this could put the headstock below the table (maybe) and if so the headstock could function like a router or pin router but are there any other advantages.

I am trying to sell myself on more needing the upgrades than just wanting them. Please help me understand this.

Hey, SHOPSMITH - a really good, all inclusive marketing video is in order about now. You can quit teasing with these tidbit releases. They worked. You have our attention.

Dusty;
With the current SS when the unit is in dril press mode the table is always under the headstock. In a shaper machine the cutter comes up through the table. With the higher speed and torque there is an advantage to having the bit come up through the table. However this would require the table to tilt to the right a full 90 degrees which I suppose could be engineered.
Currently if you want to rout it is like having a conventional router mounted in a stationary position and passing the work under the cutter which some people don't like to do because the dust is also above the work and would be somewhat difficult to control. With the cutter below the table I believe that it easier to control the dust and with the cutter being covered by the project it would probably be safer. I think that I will stay with my 3 1/2 HP router and the router table for the present. When I get my Powerpro probably in late August I may rethink this issue.

The original Mark 7/VII did tilt both ways and the under the table headstock was function #6. That function was the reason for being able to run both directions. The table does tilt both ways. +- 90 degrees

Function #7 was the 'vacuum'.

Bill, I can see the concept of a router table but there has been no discussion about changing the table to accommodate either a router or a shaper. I do not see that concept as an attraction because it puts the table saw in competition for headstock time while routing/shaping. I spend a lot of time routing and I don't want to sacrifice table time to the router.

If these are the only features enabled by pivoting on the left side, I don't need it.

If you make a special water catch pan and mount a grinding wheel on a tall arbor and add a water drip you can run it on the lowest speed and do lapidary work on it...

You could also use it (same concept) for sharpening like this.

I don't mean to hi-jack this thread, but the original announcement said, "RUN FORWARD OR REVERSE: Upgrade now to enjoy the benefits of electronically controlled forward or reverse operation and you'll be able to perform bi-directional sanding, with-the-grain cuts and safer, under-the-workpiece shaping operations that were never before possible".

Wasn't under the workpiece shaping operations possible with the speed increaser? What is bi-directional sanding, and how does reverse make these operations possible anyway if they weren't possible before?

Sincerely,

To answer part of the questions: The reverse motor direction operation allows one to mount a shaper cutter upside down so as to cut on the underside of the workpiece rather than the top. In order for that to work, the spindle must also reverse direction. It also allows one to do under the table cutter mounting without any additional device(speed increaser), and also has the desired speed without it.

Reverse sanding - not sure?

With the grain cuts - Not a clue!

It's called "puffing"...
From The Free Dictionary:
Puffing is generally an expression or exaggeration made by a salesperson or found in an advertisement that concerns the quality of goods offered for sale. It presents opinions rather than facts and is usually not considered a legally binding promise. Such statements as "this car is in good shape" and "your wife will love this watch" constitute puffing.
=============
I first became aware of the legal definition of puffing through the real estate profession which if it used any more puffing everywhere would be "the windy city".

Lathe-turning articles sometimes cite the advantages of rotating the workpiece 2 different directions for final sanding.

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?
