Hercus Parts
Hi There,
Nice job on the forum guys, very informative.
Ya hav'nt lived til you've owned a Hercus.
Anyway getting back to the serious stuff, would any of you guys be able to tell me what change gears came with the Hercus craftsman model lathe if any?
I purchased this lathe about a year ago and it did not come with any extra change gears and I was wondering what gears are needed if any to cut the range of threads displayed on chart or plate attached to the lathe.
Regards Marc.

Hi marc
I dont know what gears are standard but if you have the plate that tells you speeds and feeds it will list the gear trains needed for the different thread pitches and feeds. If you are lucky it will have a diagram showing you what it looks like. My little myford uses change gears and once youve done it a couple of times its pretty straight foward. Decide what thread pitches you would like to be able to cut and you will have an idea what gears you need to start collecting.

Hi Darrell,
Thanks for the advice, no diagrams, but found gear sizes on one of the attached plates [bit hard to see].
All I have to do is find out what size gears are currently on the machine and purchase the others as required.
Sounds easy, but I bet their like hens teeth.
I trust your Myford has served you well, great little lathe.
Anyway thanks again
Regards Marc.

Hi Marc,
Be aware that if you source change gears from the States for say a South Bend lathe, to use on your Hercus Craftsman, the pressure angle is different. From memory, Hercus use 20 degrees, South Bend 15 degrees.

G'Day Ken,
Thanks for the info, I recall [now that you mention it] hearing about the 2 different angles and I will definitely double ckeck before purchasing.
I have heard of people running the different angles together resulting in a noisey gear chain and premature wearing of the gears, not something I want to get involved with, sounds a tad rough to me not to mention mechanically incorrect.
Cheers Mate Thx Again.
Regards Marc.

Hi Marc
Looks like you need to download
Lathe-Tutorial.pdf the classic 'text book of turning'
(www.bbssystem.com/manuals)
