Help identifying which tool holders i need

[Woody.v8]

I could do with some more tool holders for my quick change tool post but I don't know which type I need?, I've borrowed a couple of different ones off people but they didn't fit.

looks like a T2 tool holder but the dimensions are a few mil off

As said, looks like T2 same as mine but don't want to get it wrong, send your sketch and photos to RDG tools and they will tell you. Thats what I did.

Avoid rdg tools, useless chinese junk.

Bison make quality european copies

It doesn't match the t2 measurements

What's the toolpost make? Dimensions for that, especially the Vs. My Rapid one differs slightly from the Dickson dimensions, the tool holders overall width is slightly wider, the Vs are the same, but more importantly the cam locking is slightly more recessed into the tool post and every aftermarket tool holder I have bought have had to be ground out there to make fit.

Did the toolpost come with the lathe? What lathe is it? Have you measured the post and other holders and checked the dimensions against the pdf? It maybe that you have a knock off version, possible if it came with an Asian lathe.

...but they didn't fit.

In what way did they not fit?

Remove the eccentric clamping bolt/cam and the top hat part that pulls the holder into the post. If the holder fits the vees in the post, but does not clamp up, as above, you can make modifications to cure this.

If you have two holders already and want to buy ten more, it would be better to modify the ones you have to match the new ones (i.e. pick whichever route is shorter).

It is a gate lathe which as you say is a Colchester copy and the toolpost may be unique to them, looks like I'm buying a new toolpost

I can't remember now but I think the vs didn't line up, I'll see if I can get it again to see what exactly it is.

Yes it's on my tomorrow todo list

The only measurement that is desperately critical is the measurement of the Vees to each other

I didn't say buy from them.

Those gate machine look very like the many far east machines from warco etc, so tool posts will be a copy too.

This is the lathe ,it's well built with no play anywhere and accurate for repeatability

Right, emailed Gate and they are specifically for that lathe/tool post and they are £105+vat each.
So it looks like A, I'm making a few or B Get a new tool post and start again

This might give you an idea of how to make some.
May be worth checking with @Dr.Al as I think he changed the toolpost on his Harrison m250 for something else, possibly because it easier to replicate the holders
