Can G110 became rotary?

[orion613719]

This is my idea, can it work?
I don't want to buy one more machine for cutting...
Just want to make an adapter, let G110 had two function...

Re: Can G110 became rotary?

Looks like your design might work.

Don't know if the motor is heavy duty enough to act as a rotary buffer however.

Re: Can G110 became rotary?

Even if you could get it to spin, or even spin more than it does now, I don't think the power is there to do rotary correction...

Re: Can G110 became rotary?

My opinion is the real rotary use 7" or 8" pad, so it need more power.
But G110 use 6" pad, so... Is it possible?

Re: Can G110 became rotary?

Rotaries can use the same 6.5in pads the the PC uses.

In my opinion, it could work - at a lower speed. A rotary is able to spin a pad at a high rpm. Plus, it is able to maintain that speed under load. When it makes contact, it doesn't stop or slow down drastically.

So, while it may work in the lower rpm range, I would be worried about burning up the motor. The stock motor is a 3.7 amp version. The Dewalt DW849 has 8 amps and even the Metabo Mini rotary has a 10 amp motor.

Better question is: Is it worth it?

Re: Can G110 became rotary?

Well Since the G110 is more powerful then the G100 you should be able to make more paint correction thenbefore. How much more? I don't have that answer.

If you are just a weekend warrior I would get the 29.99 Chicago electric rotary. It is a pretty decent machine for occasional use.

Re: Can G110 became rotary?

I already send the drawing to a factory yesterday, I can get the parts next week.
I will post the result here...
(Because the parts is free, so I can try it...,
if it's not free...due to your suggestion, I will give up...)

Thanks for your suggestion!!!

Re: Can G110 became rotary?

I can’t really tell from the drawings you show, and I haven’t taken apart a G110 so I don’t know how it’s actually built.

But it looks like you’re basically extending the drive shaft. In that case I have to assume that you’ve figured out how to remove the eccentric mechanism and counterweight assembly so you can access the drive shaft.

Assuming that all works, now you have an underpowered rotary machine (the G110 has a 4.2 Amp motor, professional rotaries have 6-10 Amp motors) that runs too fast.

The G110's final drive runs 2560 to 6700 rpm. You want a rotary to run at least half that speed, preferably a third. That means you’d need to redesign the gear drive mechanism as well.

Unless you do that by adding on something like a planetary gear reduction after the stock drive (bevel gears like the G100 I presume?) you won’t be able to change it back and forth between DA and rotary.

I would also think that the bearings of a G110, being intended to support DA polishing (i.e. flat on the finish), would be designed primarily for coaxial thrust loads, not for the sort of off-axis loads rotary buffers are subjected too. Cantilevering the plate/pad out on your drive shaft extension multiplies any off-axis loading and may lead to premature bearing failure.

Keep in mind, once you tear apart the machine, the warranty is no longer valid.

Sweet! No sound in the videos but great documentation. Thanks for sharing.
