For the Econoseal / junior power-timer/ Superseal style 2.8's you would need an open barrel 'F' type crimp tool with correct die set
The cheap ratchet tool on ebay looks like it has a die set that might 'be made to' work but is still a generic tool so possibly not....
You can get a cheap non ratchet open barrel crimp tool that you have to use in two hits, once for the insulation and once for the wire conductor
many thks
i have got one as per pic , but no good, terminal is too small
