Pin adapters. Crimp on your fine strand and gives you a nice solid. Here is an example: https://www.ilsco.com/Ilsco/ccrz__ProductDetails?sku=F2C-1%2F0-1%2F0-ILSM-ILS&cclcl=en_US
Otherwise you need to get proper ferrule crimpers to do the big size ferrules. Something like this: https://www.ferrulesdirect.com/collections/hand-crimping-tools/products/vag240 (interestingly, the above company does have cheap pin adapters as well. Perfect for going with cheap inverters?)
