Well, that's good that you have qualified help, and that you want to read to increase your knowledge. We just don't want you to get hurt, nor get too frustrated with your project, but everyone has to learn at some point to accomplish what they want to do. I am glad to see people of your age have the inclination to do something like this. We are here to help. Just note that sometimes I am away from the computer for days at a time, as I will be next week. I will answer any questions when I get back.
Meanwhile, take a look at post number 18 on this thread:

Carr Precision used to make parts for Homelite conversions, and a phone call to him might set you up with a prop hub. I am sorry that I am just so overwhelmingly busy at this time that I can't offer to make you one. Anyone else out there???
Good luck and be careful,
