I am using a vision 1212, and want to use my featherlite/ezrider to help with consistent pressure while diamond drag engraving.
Do I need to use a solid collet? My engraver currently has a split collet.
Thanks!

The purpose of a featherlite adapter is to have the cutter "float" (on the adapter's spring) while engraving.
Using a collet, would lock the cutter in a stationary position, thereby, rendering the adapter useless.

So, I wouldn't use a collet at all? Not even a solid one?
Wouldn't this cause damage to the spindle?
I am engraving into soft metal (pure silver)... so I don't need a lot of pressure.
I'm not satisfied with the dragging results using the surface selecting ability of the 1212 itself (proximity sensors).
I have a different thread on my problems.

Let's make sure we're understanding the same definition of a "collet."
The cutter is still loaded through a spindle, but a collet is a means of clamping the shaft of a cutter, close to the business end.
You may be referring to a nose cone depth regulator, which can be made of steel or delrin and rides directly on the surface of the substrate, allowing the end of a cutter to protrude past its opening at a user-prescribed depth.

See attached image.
One is split, and one is solid. I assume the split one is made to "clamp down" on the cutter. Do they both "clamp down" on a cutter and hold it tight?
I wouldn't just use the featherlite with the draw bar in place, but not use a collet? If I do this, won't the spring action of the featherlite be useless, as it won't be screwed into anything solid?
I only have a split collet, and don't want to purchase a solid one unless it's necessary.

It appears that you can use it on the solid collet, non-compressible. This is assuming that the bit is long enough to make it through the bottom and still be grabbed by the adapter.

OK,
I've worked on a Vision machine, with that (split-collet) spindle configuration, although, I've never tried to use a featherlite adapter with it.
As you're discovering, they're not condusive for use with a burnishing adapter.
Have you tried finding a delicate balance, between barley tight and loose?
If that makes any sense.

The collet is nessisary to lock the draw bar into the spindle creatinga place for your spin in cutter. You need a split collet to lock routing cutters in place so that your machine controls the depth. You need a solid collet so that your machine can have limited travel while your cutter floats with a somewhat constant pressure across the engraving surface. The later of the two is for burnishing and diamnd drag engraving with a long cutter such as a rotating diamond. You may want to talk your cutter supplier about dragging a cutter of this type. I have been succesful doing silver belt buckles this way in the past. The machine doesn't have quite the finess and the featherweight gives you that extra soft touch.
