I, too, have built no less than THREE receivers here in my 40 year tenure as a Ham. Allow me to share my experiences along these lines with you & the group:
(1) A regenerative receiver may look easy to be build, but it can drive you to drink very quickly making it work right!
(2) IF transformers CAN be homebrewed---I have seen at least two links on-line with information on exactly how this can be done. Google it.
(3) A hand-wound enamel wire coil on a plastic pill container sealed with clear fingernail polish works just as well as a piece of B&W coil stock.
(4) Do NOT start "BIG" & overly ambitious in the making of a receiver---you'll quickly become overwhelmed, & disillusioned. Start small first, & learn from your mistakes (a good beginner's project this way is "A MATE FOR THE MIGHTY MIDGET", ref. 1969 ARRL HANDBOOK, & April 1966 QST).
(5) THERE IS NO FEELING OF ACCOMPLISHMENT IN HAM RADIO AS THE JOY & SATISFACTION THAT YOU'LL DERIVE WHEN YOU MAKE TWO-WAY COMMUNICATIONS WIITH YOUR FELLOW HAMS USING A STATION THAT WAS 100% CRAFTED BY YOUR OWN HANDS!!!
Don't be intimidated to start, don't give up---remember, THE LONGEST JOURNEY BEGINS WITH THE FIRST SMALL STEP...!
