Threading mill, Simon Hope

[Tinyjames]

So I've been doing some research on threading Jigs and found the Simon Hope threading jig.

so I was wondering if anyone could recommend the system. now my lathe only runs at 2000rpm

I have a collet holder for the cutter and pen jaws on my chuck so i'm sorted to hold bit and pen blank

link for the Hope system

While I suspect threading pens could be done with a similar jig, that one wouldn't be able to cut small enough threads for a pen.

Pierre--- has mastered it on wood pens so he is one of the men to ask.

Desert Ironwood burl kitless

I wanted to make a fp with this wood for a long time, but I could not find a burl that met my expectations. Patience paid, I recently laid hands on a very nice piece! :) It really takes threads nicely. Thanks for your comments.

The other being Bruce BRobbins629. https://www.penturners.org/threads/square-multistart-threads-on-wood-lathe.131087/ Unfortunately you will have to wait for Bruce to recover from his recent accident before asking him.

 

[Tinyjames]

Curly If I used a smaller cutter on the Hope Mill/Jig would that make it suitable for pen threading

 

[Curly]

It isn't so much a function of cutter size but of the thread pitch his tool has to work with. If you wanted to make a 12 x 1mm pitch thread equivalent you would be cutting 25 teeth per inch (TPI). The pitch he was using, sorry didn't watch all of it, was 10 TPI. If he makes finer pitch spindles that would be different but as his market is aimed at box makers. If you are wanting to do multi start threads then you might be able to work with the Hope jig or one of the others on the market doing the same, if there is provision for indexing or you know a way to do it. Bruce's jig obviously does it but you'll need to make one of your own. If you also plan on making threaded boxes then you have it for that if the pen threading doesn't work.

 

[Tinyjames]

Curly Thank you for you reply I have written to Simon Hope so I will wait for his answer

The Simon Hope jig uses a master thread to duplicate the thread on the item being threaded so , provided you have a fine enough master thread to use in it you could do it BUT the system is basically for box making. I have talked with Simon in person about it when he was demonstrating it.

The cost of a custom set of cutters would be prohibitive. To cut the inside threads would take a micro cutter, never saw one so it would either have to be made by you, or you would have to have someone make it. It would be one of kind, not like the group buys where a lot of people buying them brings down the cost for everybody.

That is why most threads on custom pens are made with tap and dies.

 

[FGarbrecht]

@Pierre--- uses a shop-made custom standalone threading jig using a home made cutter. I use a jig that attaches to my metal lathe and uses a dremel to turn a high speed thread mill. Tiny thread mills are available (I use Micro 100 thread mills from Amazon; they cost anywhere from $45 to $80 or so). This way you can cut tiny threads in any pitch that the change gears on your lathe will allow.

so I have in my Amazon basket some items for the start of my jig.

I'm going to use a 1/4" router as My lathe only has a top speed of 2000 rpm

My lathe chuck has a thread of 1"x8tpi so the next thing I need to source is a adapter from chuck to threaded lead screw but I don't know where to start looking any idea where I should start.

I would really like to see @FGarbrecht and @Pierre--- home made Jigs would it be too much of a ask for you to post a photo of your finished Jigs

Have you seen the article in the library here, called the 'Incredible Threading Machine ' ?

 

[Tinyjames]

yes I have and down loaded thank you @Ironwood

If I am reading that correctly you want to make an adaptor to effectively screw into the back of your chuck on the 1" x 8tpi and then fit the brass lead screw flange on your threaded portion? If that is correct you could make an adaptor or maybe one of the carving attachments you go an get to attach chucks for work holding ? instead of attaching it to your workbench attach it to the brass flange.

Sure - pics of my setup:

that's very clever, using the lathe head gearing you have a vast range of longitudinal feeds to generate the desired tpi !

Nice set up.

Thanks. It was a major pain in the a** to put together but in the end turned out to work very well.

I have seen Peter Herod use acrylic resin inserted into the ends of softwood blanks ( box making) then hollowing and thread chasing into the acrylic . Using your set up you could make some beautiful small lidded containers ? Just a thought. I mean it never hurts to keep SWMBO supplied with desirable items does it?

Smallest a friend ( Tony Kitchen an expert professional turner ) has hand chased was a 3/8" wide by 3/4"tall threaded box . Then he showed me the wine goblet hand turned with tools made from nails which fitted inside it !

oh forgot to say that( Tony's box) was threaded either 40 or 48 tpi , by hand on a variable speed wood lathe.

I can do 20 and got away with some 28 tpi threads but as yet matching them up is proving challenging for a screw fit lid.

keep experimenting and hope all goes well

I made one a few years ago, it was basically based on the various commercial units.
I used a camera 4 way rail for a cross slide https://www.ebay.com/itm/2X-Rail-4-...201085?hash=item3b58e0d8fd:g:AesAAOSwKThgRZ3Z
I used HDPE blocks instead of aluminum to construct the parts. I also used a mounted Foredom handpiece as my cutting power source.

The had part was the cutting blade, I never found one small enough for pen making. But I did use it for making boxes.
