content: Not personally, but it shouldn't be difficult. You already have the quill stop, so mounting an additional ring with set screw underneath it on the column could be a solution.

content: Quote from: German_EE on September 29, 2018, 08:26:36 amWhen using a drill press, the vertical movement of the bit is controlled by the lever. Release the lever and the drill bit/chuck rises to its highest position under spring control.A quill lock is a mechanism to lock this vertical movement at a fixed position.It's the sort of thing you might need for doing something like this:Fit the sanding drum, lower the spindle to the height required and then apply the quill lock. This saves raising and lowering the table over and over.

content: Hmm. I'm not sure what you mean. Do you have an example of this?

content: An example of what? How it works?There will be several ways to implement the function. Which can be used will depend on the specific construction of the press.The unit you have indicated does not even have a quill, but the function of holding the drill in a lowered position - which is what a quill lock does - is still possible. How you can do this, though, will depend on how the lowering mechanism actually works ... as in the detail of the mechanism.

content: @Brumby I was trying to reply to @Benta not you, when he said " You already have the quill stop, so mounting an additional ring with set screw underneath it on the column could be a solution." It seems he knows of a solution and I was asking for more details.It seems clicking "reply" does not include a reference to the person who you're replying to.

content: To expand on the idea:The 28606 does not have a quill, so talking about a "lock" here makes little sense.What it does have is a column stop, this one:https://www.fluidonline.de/proxxon-28606-16-federdruckteil-ersatzteil-fuer-bohrstaender-mb140-s/a-5002/?ReferrerID=23Seeing how inexpensive it is, I'd just buy this part and mount it on the column below the head assembly. You can slide it down when not in use, and slide it up against the head when needed. In that case, the lower part of the head is sandwiched between the normal column stop and the new part, and won't be able to move.
