I have done some drawings - doodles and many parts are clear, BUT having a little trouble making my mind over interchangeable adaptor sleeves.
Very much considering using parallel MT1 and MT2 adaptor sleeves. Tempted to choose ONE diameter for MT sleeves and ER collets. Only trivial question seems to be choosing one inch diamter or 25 mm diameter, but looks like I have to split order over several shipments (which is no big deal in UK/US, but here if I order something from UK it is 20€ or so). I don't want to use MT2 to ER adapter, because I learned that mass here is not friend with small reamers.
1: Suggestions on shop that I can order all parallel sleeve adaptors (MT1, MT2, ER20 or ER25) on one go
2: Are the adaptor sleeves generally ground outside consentric with MT-cavity and end dimple? My cunning plan is to grind 1" MT adaptor outside straight and to 25 mm diameter between centres if I can't source 1" ER holder.
