Burnerd ec collets...dismantling

just out of interest I made a backstop for my EC collets as trying to find one was nigh on impossible. well worth the little work and have used it numerous times.

Ah, I think I see now, I need to squash the main collet body to allow the retaining ring to come off. A 6-jaw chuck would be handy for that. Which I don't have so I'll have to make something.

I think that the larger sizes have room to take the blades out by pushing them into the middle but not the smaller sizes since each would collide with the opposing blade.

Does anyone have any other suggestions of how to store these things without risking corrosion? I think I like the idea above of sealing them in plastic bags with some sort of corrosion inhibitor, slide oil or WD40.

Camphor or moth bxlls (orbs) are supposed to stop corrosion. Have one in tool box.

Would it be possible to place some kind of hose clamp around the front diameter of the collet?

It should (just) not touch the spring ring so that the latter can be moved out of the groove all around.

Then remove the hose clamp and push ring further off.

But perhaps the clamping height is to short for this.

I'm pretty sure I dismantled all of mine without removing the ring off any of them. The springs come out easily enough with long nose pliers and a slim flat blade screw driver.

Thanks all, I might investigate those ideas.

Unfortunately, the reason I'm asking is because I bought a set of these on ebay (for a considerable amount of money), listed as excellent condition which are, of course, covered in corrosion on the outside of the blades. I wonder if there's any point in doing anything since I don't know of a way of treating the corrosion that wouldn't ruin the accuracy of the collets, which is their entire point.

Why do I never learn not to trust people on ebay?!

If you've only just bought them then raise a dispute ASAP. Excellent is a pretty strong word to use, if it said good then its going to be subjective, but excellent doesnt leave them much room. Either get refund or a discount. Its tool steel so rust will pit the surface, although if it is light you'll probably be OK if you chose to opt for discount and some evaporust.

Dog, if the item was incorrectly described raise a dispute, as for rust prevention do a forum or Google search and there will be thousands of answers to a perennial question.
