IDOD neck turning tool?

[bozo699]

Exterior....NOT Interior!!

I thought it turned the inside and outside?... I thought that was there big selling point.... no donuts.

I love that it stops on the shoulder rather than the case mouth.

Yes!.... should be way more consistent huh?

Yep, the video clearly states it cuts both inside and outside.

Did you watch (and listen to) the video? What does the "ID" in "IDOD" stand for?

Everybody must have more money than me. I can't even THINK about buying one of these! Lol

Thanks for the interest. Yes the ID of the name IDod stands for Inner Diameter. The OD of the idOD stands for Outer Diameter. The machine was developed to cut the INSIDE and the OUTSIDE simultaneously. The only neck turner developed to do that. This ensures virtually zero case neck thickness variation. With a mandrel you will always battle having not enough clearance and creating a bunch of heat (friction) even with lube, or too much clearance and not getting a perfect thickness cut. If you measure the inside of a case neck after mandreling, you will not see a perfect round hole, it will vary. Sometimes a little, sometimes a lot. The speed at which we can cut with the IDOD is the second main benefit. 300 PCS an hour is what we can do. There are some cons to this though, and I will always be upfront with them. If your trying to take a couple/few tenths off, this isnt the machine because the neck and body will not run true enough to get a 100% cleanup cut. You can turn brass right out of the box though. Especially higher end brass lines like Lapua, Peterson, etc. If you run an expander only in your brass to go up in calibers you are probably going to have neck to body run-nout issues and in turn, not be able to get 100% cleanup on the necks. We always recommend if you are sizing up, say a 6.5-284 to 284 that you run it in a full length die to straighten the neck to the body. Must use a NON bushing die to do this, as bushing dies allow the bushing to float in the die and doesn't force the neck to go straight to the body. We are making 6-220 Russian dies now to straighten the neck out to the body after expanding.

Here is a couple videos showing types of methods used for brass prep and turning:

220 Russian expanded to 6mm

6.5-284 after expanded to 284

Heckuva machine for sure

That's a lot of quality machine for the money! Very impressive. I've always been leery of outside turning off a mandrel, knowing that the inside of the neck is never cylindrical, either before or after expanding the neck, due to springback. Kudos!

I do not own one.....yet....but saw it running at the SWN's this year and it is truly a thing of beauty. The speed at which it runs without creating heat is kind of a win..win! The cost is really the only downside

 

[RegionRat]

The demo they did for me at their table during the BSWN was very impressive. The blends at the neck shoulder junction were beautiful.

I had seen the videos prior to the match and was trying to imagine how the adjustments worked. They showed me how that is done and they were very simple to use. The brass came out beautiful.

I wonder if a fella could use a feeler gauge to set the cut?

I would like to thank everyone for their thoughts and Bryan for replying and adding the videos

That's what I do with my regular old hand held turner. Works great.

I use a feeler gauge, too.

The IDOD machine is a breakthrough in turning necks, however turning the ID only in this manner would be my ideal.
With the brass in a FL die during turning there should be no need to be concerned with the OD condition or not being concentric.

1000 cases in 4.5 hrs that are perfect and I’m a picky bastard! Fred B was here yesterday at the shop, showed him the machine... I turned a piece, ran it on a Concentricity Gage, measured it...... he’ll be getting one!

Wouldn't that be reaming using an RCBS reamer die?

[Bryan Blake]

A reamer will always follow some sort of hole and/or axis. I actually started my neck thinning process about 10 years ago this way. An rcbs die, push the case up in the die with the press, then use a drill and ream the case down from the top. The results were not great at all. So then I started boring the cases in a CNC lathe, then turning the OD. Well that required two tools and actually took a fair amount of time (old CNC lathe). Then I started turning the od and boring the id on a manual lathe with the case held in a 5C collet with the case taper bored into the collet. This was again done with two separate tools. Wasn't very consistent and still slow. So then I clamped a boring bar and a turning tool together in the same tool holder and just tapped around the tools to get the right thickness. Wasn't a precise way to get a desired thickness. But it did make a good consistent neck. I started to design a tool head to use in my lathe to do the turning with precise adjustments, but I always had to tie up my lathe to turn necks. What to do? Make a bench top model I can dedicate to the process, but at the same time make it just as precision as a precision industrial lathe. The IDOD was born. In September of 2019. Hundreds of hours (literally) in R&D and improvements. I did not want to out a gen one version out there that was not great quality and have all the first customers not have an excellent product. We spent months perfecting the process of manufacturing and keeping the cost as low as we could without sacrificing quality. The number two serial number all the way up to what is now 60+ serial number is all the same machine. No changes or improvements have been needed so the first guys who bought them have the same machine as the purchasers now.

Is it expensive? Definitely. But quality usually is. With over 150 parts and when dealing with .0001" resolution it just can't be made and sold for 700 dollars.

Thank you to all the customers and people of interest for your support.

Can email me at sales@fclassproducts.com with any questions if needed.

 

[bigbulls]

I wonder if fclass will ever consider turning necks commercially, I know a guy would have to buy/have made his own case holder, but then have them do it with there machine? At a cost of coarse.

 

[fatelvis]

If I bought one, do you think there'd be enough interest in me doing other people's brass on this site for around $.50 apiece? I want one, and I'm willing to work for it!
