Looking for info on factory complement of gears & threading combinations.....just brought in a lightly used Barnes 4 1/2 ( last patent date is 1887) minus most of velocipede gear & am very far down the learning curve on these little foot drive machines....two interesting things are a carriage longitudinal feed dial graduated in .050 for a 1/2 in. & t/stock index graduations ..strange for a 19th cent machine w/ no CROSS feed dial ..suspect aftermarket ..will be mounting a c/shaft & 1/3 hp motor , either on a frame behind or on the wall , & returning it to usefulness. hard to justify w/ 5 tooled up lathes , but need something to do to still keep me moving this winter...
Now , it is geared for an 8 pitch thrd, using a 16 T on spindle driving a 52/40 compound & 88 T idler to the l/screws......planning on cutting remaining gears ,along w/ a set for 15 in prentice ( also 16 pitch ) & hoping some one has info on which gears came from factory & various thrdg combinations ( from a chart maybe ?) .....reckon i can figure from what i have , but wud like to get what barnes considered "correct "# of gears & their threading combination....tnx for your help
