Can anyone please help I have a old 9" Hercus which I have had a riser block made to lift the headstock so that I have now 13 1/4" diameter clearance
As It is now larger I have also purchased a second hand toolpost holder but I need to know at what height should the toolpost be as I have measured 6 lathes and all are different and the original single post is no use to measure so can anybody shed som light as I have a swag of old 9" Hercus Holders but will be using larger tool holders or a shimmed up carbided tool
I would gladly show you some photos but I am still not able to work that bit our but if Ken if you read this can you put the pictures up
I have for the last 11months been restoring all bare metal parts have been electroplated zinc colour and on buying new Chucks found the centre height to low so I found a toolmaker who made the riser so it sits on the bed flat and the Headstock sits on the riser
This height problem is the only Flaw I can see in the Hercus but as a hobby machine fine but I wanted to machine brake drums and discs and this 60 year old machine has no wear except the screws and nuts and I will reckon when finished will be a great improvement as Hercus overbuilt this small lathe so I am using the extra size of the machine to it's fullest
Am I crazy or do you think a good idea ?????
all the best Derek
