Hi Sean,
I use the same thing on my Colchester Studen 6", mines a T2……… on fleebay………….
eBay item number:
331640818430
worth a look, bit more money than you want to spend….sometimes they come up used but anything decent is not CHEAP..
..you won't regret spending the money……….what ever you buy make sure you can get used tool holders that fit……some suppliers make them so that you can only buy from them……..they are not interchangeable…………someone else will advise if you need a T3 for your machine…..
good luck Clogs
