Bridgeport Cherrying Head. Joined Dec 30, Messages The Bridgeport mill I purchased has a cherrying head hanging on the back. I purchased an instruction manual from feeBay and have a basic understanding of what it is supposed to do. YouTube videos are lacking in content and was just wondering if any of our members have experience with this device.

John, I would love to have one for "just in case". But the shipping alone would probably exceed my interest level for what little use I would have What is "cherrying"? What exactly would it be used for? Thank you for the video. I've heard of them but never had seen one. Without CNC I guess they would be quite handy for clearing out molds, etc. I wonder how they came to be called "Cherrying" heads?

Any info. Best regards, Stan-. Quote: "I wonder how they came to be called "Cherrying" heads? The cutters originally used in these attachments were similar to what we now would call a ball end mill.

If you imagine a ball end mill with more than four flutes and a shank smaller than the ball, you can see the resemblance to a size and shape of cherry. Just needs the wiring sorting before I can try it out. I have some keyways to cut in some gears that I cut on the same Bridgeport. Now the question: What is the correct direction of rotation?

I realise that the ram will reciprocate whatever the motor direction is but there are thrust bearings on the worm shaft which mean that the direction is important. There should be a small plate attached near the stroke adjusting dial showing the correct direction, but it is missing! Tags: None. I am going to guess that it works no differently than a crank shaper. If so, the travel in the cutting direction should be slower than the "retract" motion Comment Post Cancel.

On looking at the drawings and parts list in the Bridgeport manual, it doesn't appear to have a quick return motion as is utilised on a regular shaper. It uses a worm drive. I think it should work in either direction, but the motor drives the pulley clockwise, whon you look at it from the top. I have mine in pieces on my workbench, if you want pictures of the insides.
