My New Shopsmith Mark V Model 530

[reible]

Hi,

I like the idea of a 530 design, that being a few modifications over the 520 but not a total redesign or something that will cost me $3500.

I like to thing about an updated design, maybe calling it a 600 with lots of new features, like maybe the new motor, electronic controls etc.

And maybe a radical design calling it a 700 series. Here would be the ultimate that would break the bounds of being tied to the old days and old attachments.

So if I might, here are a few things I'd like to see in a 530.
1) new/better dust collection for the table saw
2) new design for the lift
3) new self adjusting out feed that is tip proof
4) active power factor control
5) safety dropout power switch
6) secondary power switch plug in
7)

For the 600 series
1) dynamic braking
2) larger speed range (say 100 to 8000 rpm)
3) selectable "clutched" outputs (so you could have the jointer mounted but not spinning while using the saw etc)
4) detectable coupling that would limit speed of shopsmith depending on what is attached
5) hour meter to track usage for PM
6) optional "legs" to make shopsmith shorter or taller
7)

Well I'm going shopping but you keep going without me.

What is needed now is an engineering tech to mock this thing up and run some "real world" tests.

If I would put this beast in my table saw and found that it slowed even just a little bit, even just momentarily, I would go back to what I have now.

Someone may have already done this, I seem to remember a post. Maybe not on this forum.

Yes it HAS been TRIED.

There are several good reasons why AC induction motors are used almost universally(pun intended)!

They work, they are efficient, they endure(with good bearings), they have a good load range...........

The economics just are not there for small DC motors. AC induction motors work better at less cost.

All it takes to 'start' an induction motor is either a start winding/centrifical switch(high starting torque) or capacitor start/run design(lower starting torque). Even less if you have 3 phase power source.

DC motors require all sorts of extra gadgets to start and control them and keep them from self destructing.

In short. What we have IS better tho not as EXOTIC/S--Y!;)

Sorry but I'm against the electronic controls. To prone to failure and the cost to replace would be greater. But I like the idea of the hour meter, but have a resettable, and total display.
