Threaded insert jig – HOW TO MAKE
How to get the dam thing straight in!
Ok, not a big problem, but a problem!

Here are the challange.

Idea! A jig so I can control the angel is 90 degree.
Solution a pice of scrap wood, some thread in a ‘nice’ size, and ofcourse the same thread as the inserts inside.
Draw up a hole that fits, the hight of the threathet insert and some extra for a nut.

Some cutting at the tablesaw.

Some more cutting, this could be done with a chisel… (Perhaps it’s starting to be borring, but hold on please)!

Some marking, remember to measure twice…
To find the center, make a line from corner to corner from both sides (no need to measure).

Choosing the right drill bit, just a little to big (if you will use the jig a lot, you might want to use a hollow insert of metal in the wood).

A hole are made (amazing).

Putting the pieces together.
Start with a wing nut, then a nut to hold the wing nut in place – then a washer, and stick it through the wood from the top – not put on a washer, then two nuts and leave enought threath free to mount in the threathed insert while mounting.

Ready to make a move.


Job done!

I did make a little change, I put a doubble nut since those locking ones are not staying…. (Learning by doing).

Hope it can be usefull, it helped me.

Very good idea. I was fighting with this very challenge just recently. Thanks for sharing. I will make one of these jigs for sure.

Thanks Mads. A great idea. And getting threaded inserts in is only a little problem until they don’t go in straight! I will definitely be making one of these soon.

Love this idea !!
I have ruined many inserts with the screw driver
turning over the slot for the screwdriver on the insert.
This is a fantastic idea : )

Mafe, that little fixture of yours is great and foolproof. Necessity is the mother of invention!! I love it.

I have used these inserts and they are hard to start square. I have a machine shop so I made a steel rod that fits inside the threads on the insert. Then I drilled a small hole through the center of the rod and inserted a small roll pin to fit in the screw driver slot in the insert. I put this rod in my cordless drill and line it up square and drive it home.

There is another kind of internally threaded insert I found that drives in with an allen wrench and I have since switched to them. they are easier to start and have a real thin head that burys into the wood I cannot put pictures on blogs because I could not down load the needed software. So, if anyone wants to see what they look like, send me your E mail address and I’ll send a picture to you….....Jim

Nice jig Mafe, well made and well explained.

Does the wing nut big enough to apply required tork to thread the insert? I think I would use a bolt instead of a threaded rod and use a wrench or a ratchet to thread the insert.

And about the [THIS IS NOT A FINISHED WOODWORKING PROJECT], don’t bother and let them express their opinion. It’s one of their rights. Meanwhile, let’s talk about woodworking and let’s share positive thoughts, projects, ideas and jigs of course.

Thanks for posting.

Thanks again,
Jim: please post your jig, so we can see it, at least here, I love to learn, and I’m as you know a beginner, so I eat all the words of your guys like as if it was candy – thank you.
Bricofleur: I think you are right, that the wing nut are not to strong, I put it into soft wood this time, but on some hard wood it might be a problem, so yes your idea will come in handy, I was thinking also to put my accudrill first, but even on slow speed it might be too fast… But perhaps if you have to put a lot in a short time… And now you are there: ‘I love all your jig posts’, so than you too.
