I am building a home made index head from a new 40:1 gear box i bought off ebay for 29 bucks. Mine is an English made David Brown for a piece of surveying equip but any Boston or eq GB will work. I wanted a smaller indexer and this one has a 2 1/2" spindle hole centerline. I am gathering up metal for a spindle with a 1 1/2x8 thread turned down to 3/4" to fit the hollow shaft in the out put side of the box. The imput end will have a keyed 7/8" shaft that will hold my little index plates i bought from an ebay seller in England pretty cheap. I need to make the sector arms and misc parts. Pics to come...Bob
