Axminster bottle opener question

While in the Axminster store yesterday I picked a bottle opener kit.
Craftprokits Bottle Opener Kit - Project Kits - Project Kits - Woodturning - Woodturning & Crafts | Axminster Tools & Machinery
I think I was expecting something like the bottle stopper which has a threaded piece which mounts the blank on a special mandrel. Not sure how to do the bottle opener. I think it's a 3/8 thread on the opener itself. Any youtube videos I can find show a special mandrel used which I cannot find. Some show an insert screwed into the blank threaded ti accept a mandrel and the opener when the handle has been turned. Lacking either of these options what would be the best way. I am thinking getting hold of and equivalent bolt and cut the head off. Screw this into a hole in the blank and hold in a jacobs chuck. Is that the best way.

I was thinking of drilling a hole for the bolt and then a hole big enough to recess a nut to fit it into the wood and glue it in with epoxy. Then hold some threaded bar in my Chuck and screw it on.

Thats something along the lines I was thinking. Chap in the shop seemed to think the thread which I think is 3/8 16tpi will just screw direct into the wood. Epoxy it in when finished. Not totally convinced thats the best way.

You could imagine its a chisel and your making a handle for it how would you affix the handle and there you have the answer (so many ways). How long? what type of handle? Thimple your choice I do like the illustrations Dan provided.

If you use a threaded bolt or bar then cut a slot lengthways along the thread just through the pitch of the thread for the first 5 or 6mm ish.

The reason for that is it will help cut the thread in the wood as its screwed in to it.

Use it like a thread tap, working it in two threads and then turn it back one thread.

It's a tool used to open beer bottles - overengineering is not appropriate!

The web site helpfully DOES NOT describe the thread:sob: But you can easily measure it.

My guess is that it is the same as a wine stopper (3/8x16tpi) - if I were the manufacturer of the kit, that would make the most sense to me. Drill a 5/16" hole in the blank, thread the hole with a 3/8x16 tap, and mount on a stopper mandrel (or a short length of 2/8x16 threaded rod held in a Jacobs chuck) and turn and finish the handle. Then, screw the stopper into the hold. If you are concerned about the strength of the thread, add a little epoxy, thick CA or polyurethane glue (eg Gorilla glue) on the threads before screwing it in.

The strength of the bond bottle opener comes from the bond between the metal and the wood (hence, the glue), the length of the stud buried in the wood (longer is better), and the strength of the wood at the end where the hole is. You could put a metal ferrule at that end (just like a turning tool handle), but that's probably overkill for something used to open beer bottles. Another option is to just make that end of the handle thicker - provides the additional strength with essentially no additional work or cost. And a making the end thicker is a nice design element.

Thank's Louie. I had come to a similar conclusion. Measuring the thread it is a 3/8 UNC which is 16tpi. I found a 3 inch bolt on Ebay with the same thread that I will cut the head off and use as a mandrel. I have a 3/8 tap so that part is easy too.
