in a club i once belonged to there was a fellow that built a box to hold a car batt then he rigged up a starter on a pivot that tripped a switch when you pushed the spinner into it- very well done but -very -awkward- heavy- in the end impractical
get a small flight box -dont over load- it the basic tools are all you need -go back to the pic of my plan-es this flight box so far has been the best for ME as far as starters go -buy someones (sullivan ) heavy duty starter it will last you a lifetime -sorry to hear about your dad life is to darn short take him wth you flying enjoy life while your here
