Fellow IAP members, I will be placing an order soon for one of the Hinze Tenon Cutters from Turners Warehouse but I could really use a couple of dimensions beforehand so that I can also order support tools.

Instead of using a Jacobs chuck or ER32 collet in my lathe to hold it, I am planning on using a dedicated size MT2 End Mill Tool Holder, kind of like these. I need to know the diameter of the mounting shaft on the tenon cutter so that I can order the correct size.

I would also like to know the actual diameter of the guide shaft. I have seen videos that state to use an "A" drill (0.2340" inches) and others that indicate a 6mm drill (0.2362" inches). I've been thinking maybe I should just plan on using a 15/64 drill which falls in between them at 0.2344" inches.

I'm hoping someone has one of Jim's tenon cutters that they can measure for me -- or better yet, a Jim Hinze Tenon Cutter that they don't use and would be willing to sell to me. šŸ˜

Thanks & Best Regards,
Dave

My Hinze tenon cutter is .496 and I use a 12-13mm collet for it. I use a 6mm drill bit with the shaft. Jim included the bit, so that is what I use. My tenon cutter is older from when Jim handmade them himself. I believe they are now outsourced, so you may want to verify this info is the same as the current version sold at Turners Warehouse.

Hello Dave,

My Hinze tenon cutter is from Turners Warehouse.

The mounting shaft is 0.4925 but I just use a Jacobs chuck for it. I also use a 6mm drill bit for the guide shaft.

I have the one from Turners as well and also hold it in my Jacob's chuck.
 
there have been some interesting postings showing possible holders for the Hinze Tenon Cutter here as well if you have a 3D printer. Storing all the pieces together is a bit of a challenge.
 
Dave - I'm curious why you want to use a tool holder instead of a Jacobs or collet chuck to hold the tenon cutter.

Part of it is laziness and another part is that an end mill holder will generally provide higher accuracy and repeatability with less runout because it has a more precise and greater contact surface area than a Jacobs chuck. And, although a collet chuck is typically a little more accurate than a tool holder, I started using tool holders long before I acquired a set of ER32 collets and chuck. So, I have simply become accustomed to just popping the already mounted tools in the headstock or tailstock without the need for using a chuck key or collet wrench, i.e. the laziness factor. - Dave

Thanks Dave, that makes sense to me.

Also... My inner engineer automatically dismisses the potential laziness factor in favor of the obvious results of a carefully conducted time and motion study. It is simply more efficient!

Wow, I haven't thought about time studies for a long time. At one time during my career I was the manager of all of the engineering services departments at our company which included our methods and standards, LEAN manufacturing and incentive pay program. Lots of scientific time studies of all of the processes out on the production floor. I'm sure that's where I got in the habit of having a place for everything and everything put back in its place with proper labeling and all kinds of other organization stuff. - Dave
 
Hello All,

I finally got around to uploading my 3D Model for the Hinze Tenon Cutter Kit Organizer that I designed.

Here is a link to it on Thingiverse.

Here is a picture of it:

Enjoy!

Thanks everyone. Between the original and the newer version it looks like it will be pretty safe for me to buy a 1/2" inch tool holder. - Dave

David,
Seeing that the tenon cutter shaft is .004" to .008" under 1/2" I would choose a 1/2" collet over an endmill holder. A collet will keep it centered where the set screws on the endmill holder will push it to one side and I don't think you want that.

I'm so glad that it worked out for you. It looks great, but then I'm a bit biased. :cool:

Just curious, how long did it take to print?

David - As you should be!! I struggled for hours trying to teach myself CAD to be able to replicate it, so I know how much time and effort each of these files requires from people. As for time, it seems everything takes hours...lol! I think it ran for 3 hours and a bit, but I am not really sure, as I started it off, let it run (keeping an eye on it remotely by camera) and came back to a finished project. One thing 3D printing is NOT is fast!!

Thank you again - and may I take the time here to wish you and all the ISP members a wonderful holiday season and happy, healthy New Year!

Very Cool storage stuff. I might have to have a go at building one for myself. Out of wood that is, but based on your design. I even have a laser so I can add the labels. - Dave

Dave -
That was my first take - I carefully drilled out a 8/4 piece of clear stock for each of the holes, did some organizing of how to place things, and used it for a bit. My issue was the height of the whole thing - due to the thickness of the wood, it would not fit vertically in my organizer draw, so I had to make some accommodations. Could have redone it, but.......The 3D printed one is thinner and less tall, so it makes it - barely! One thing I did do and you may have noticed is I hand engraved each bushing with the size so when I dropped them all, it made it easier to sort them out!

I've even made a few things including the "drilled" holes by stacking up a few layers of lasered out 1/8 inch Baltic birch plywood - it's about the maximum thickness I can laser out cleanly. - Dave

PS I did notice your engraved pieces and will likely do the same.
