I have ordered some stuff to make a new handle for my Tsprof and I ordered these threaded insert's of of ebay.

I have never used these before and I was thinking about using a bolt threaded into the insert then using a lead shot bag and hammering them in,I don't have an arbor press or I would try using that.

The outside diameter s 10.3mm and I have a drill bit that size but I'm putting these in hardwood,I tried using a screw in type but they were so aggressive they just split the wood and then I found out later on they were for soft wood.

I was thinking about steaming or boiling the wooden handles I got first to soften the wood what do you guys suggest.

You say you have a drill bit 10.3 mm? Then it would slip in. I wouldn't steam it or boil it as that would probably distort the wood.Yes it would soften the wood but wouldn't it also cause it to swell? I'd be inclined to epoxy it in place since it's not really a stress part subject to twisting or load bearing.I'm sure more knowledgeable folks than me will chime in with better answers. lol
 
If you have a lathe, i just saw a video this week about someone making a round ball out of epoxy, put it into a lathe and made a very nice crystal clear ball.
 
A light press fit with wood glue. Epoxy is best but overkill for this application.
 
I've noticed different woods respond differently to drilling holes of a given bit size. Some will be a tighter fit for whatever's inserted, and others loose & sloppy after using the same exact bit to drill the hole. I'd at least try the 10.3 mm bit with a scrap of the same type wood, to see how the insert fits. It'll be much clearer what will/won't work, after first giving that a go.
 
I tried the ones you twist in and they won't work and they the same deal drill the hole at 10.3mm,I think the problem is the wood is hard.
 
I think with these ones they are 10.3mm deep at the valley between the splines and the tip are a bit more then that,I thinking the same thing about drilling the hole out a bit more and epoxying them into place if I have to.

I’d still want it tight enough to have to tap it in and barely any epoxy coating on the insert. Otherwise it will act like a plug and not let the insert go in all the way.
 
That's what I was thinking to that the glue may cause pressure and even if I do get them in all the way they may push out a bit or have some other problem to deal with.

For serious hard wood you can drill and tap it just like you would aluminum with a machine thread.
Cut the threads so they are a snug fit. You might want to look into :
  • Starting taps (to start the threads)
  • Bottoming tap (so you can get threads down to near the bottom of the hole if the hole is a blind hole).
Yes I have done this they hold well.

You can also install thereaded metal inserts into the wood similar to the ones tiguy7 posted but with machine threads and tap the wood with machine threads to fit those threads.
Here is the sort of thing. Push the pins in to lock it. It's an aircraft type fitting.

I may look into getting those if the splined ones I have don't work out.

Wowbagger Wowbagger do you know the brand name of the Helicoils you posted,I tried looking for them and I would like to get those with the 4 post's you drive in after you thread the part in as far as you want.

I have seen them before but have never gotten the name,also is there a certain name for that style of Helicoil.
