FLOATING REAMER

[oneshot 66]

Anyone have experience with this https://www.ebay.com/itm/123331431551

It doesn't appear to have any axially alignment function. Only radial. Consider how many surfaces from the tailstock forward that have to align.

Edit Just read their description. They say it does compensate axially. BUT......

The description says it has axially.

Have you considered a simple pusher?

I used one years ago, seemed to work fine. I used it with a dead center insert installed in that tool, then used that to push the reamer, and held the reamer with a handheld holder to keep it from spinning. At the time that was how I could get complete reamer movement freedom. That tool is just two plates held together with two bolts. You loosen the two bolts up to get and pitch or yaw, but I was never happy with it's affect on the reamer. That's why I used the setup described above. Currently use a JGS holder for a floating holder.

I bought one of those years ago and never used it. After seeing how it’s made I realized like Dave said, it only allows radial alignment.

A simple pusher is regarded as all a person needs. Being new at this at that time, I was concerned about my ability to hold the reamer w/o imparting side forces. So I bought a floating holder that allows both radial and axial alignment. I’ve since tried a pusher and using it was a non issue

The holder I use is from PTG. They use the terms horizontal, vertical, and angular. Their webpage used to have drawing showing how it’s made but I didn’t see that just now.

I have this one and it is great. Floats on all axes just like a pusher, but has a spring to put a bit of tension on it and a drive plate so you can keep your hands away from the rotating bits.

The PTG holder really is a nice piece of equipment.

The hold shown allows some radial float but the reality is, when it is under load, it moves to center, but not necessarily to true center. A good friend of mine uses the tailstock center and holds the reamer with vice grips. Another holds the reamer solidly. Both produce good results.
I used a floating holder like this when I first started out, fifty years ago, I quit using it forty years ago and don't miss it. WH

I bought one and never used it. I’ll send it to you if you want to try it.

I currently use a Soma floating holder on my Prototrak. It floats radially and axially and the tension and amount of float can be adjusted. It also returns to center so I don’t worry about dragging when power feeding in or out of the chamber.

Thanks for offer, but Dave Tooley has beed a great help and I'm going to try his push method.
