    Default Hercus model "O"

    Hi

    I have been reading a lot of threads here as a guest but eventually had something to post. I'll start by saying I have limited experience, go easy on me

    For a while I have been wanting to learn how to use a mill and maybe getting one for my workshop. My dad lives nearby and has a large lathe and the skills so thought a small mill would compliment that. I am only a hobbyist but would love to get to the point where I can make small parts for other projects.

    I recently picked up a Hercus model "O" mill, the 3 slot model. It seems in ok condition and works but I don't have all the parts. It is set up as a horizontal mill currently (I believe this was standard?) and came with the dividing head, a vice and some tooling. Looking through the manuals I think I would also like the vertical head and obviously the tail stock to at least get started learning. How much pain am I in for tracking these down and is there anything else I should be chasing? Are the parts different between the earlier and later models?

    The actual mill itself seems complete.

    Reading through another thread I saw a picture of the gear that is put on when attaching the vertical head, I found that gear amongst the tooling. Is that all that is needed apart from the head itself?

    Sorry for the vague questions, stems from a lack of knowledge. I'll have to take some pics.

    Thanks for any advice, I wanted to ask here before I start chasing (possibly the wrong) parts.

    Just need the vertical head, dowel pins and bolts if you have the gear attached to the taper shank
    You will need a draw bar for the vertical tools, but that is nothing too special. Note that you may need 12 mm and or 1/2 inch thread depending on your tooling

    Maybe someone else can shed light on this, but I think I've heard there are 2 gear sizes to fit into the horizontal spindle, depending on the head attachment (slotter, vertical head...)

    While you've got a small mill, it is built like a tank. Enjoy!

    From what I understand the vertical head was an option. So it may not be 'missing', it may have never been purchased for the machine in the first place. If this is the case I recall reading that some of the holes that the vertical head fits to may need to be reamed or tapped to fit. Cant remember where I read this. Cant find my manual at the moment... There will be others on this forum that will know the answer to this.

    I went through the set up of my mill a few years back and was lucky that most things were there when I collected the machine. I only needed to find some bolts. If you need to see a pic or size of any of the parts you dont have, I may to able to help.

    If you are looking for any tooling for the vertical head it is a MT3.

    Good luck with getting the machine up and running!

    I think that the vertical head is different on the three slot table mills than the earlier two slot machines, not sure what they are but something to do a bit of research on, Check the AMH website, there may have been information on there about the head for the 3 slot table.

    I have been /am going through a same conversion. The vertical head for the three slot table does differ from the 2 slot.

    If the mandril/tapered shaft is not with the gear for the head then I have a drawing (courtesy of Mal at AMH) that I could forward to you. That is if I can work out how to attach the blessed file. Its a MT3 taper and presses into the gear. Good practice

    Regards

    Ulfr,

    You were fortunate to have the dividing head accompany the mill and you may be lucky enough to find an orphaned tailstock. If not you could make your own.

    Tommy thank you for the reply. Not sure if all that is among the pile of stuff that came with it, I'll look at pics and try to find it. Alot is hercus lathe stuff that may help someone here once I figure it all out.

    NHO thank you and Interesting. I got two different manuals with it, the orange demonstration one and two operator instruction books. I'll look through them for that info.

    Tinkerer thanks for that. I had to google AMH haha, looks like a great resource.

    Terry thank you for the confirmation regarding it being a different head. If you have that drawing that would be fantastic (in the event that it is missing).

    Bob thank you so much for the diagram! May indeed come in handy

    Found the instructions for fitting the vertical head. Not sure if this what you have?

    Thank you so much Terry for the pic and thank you NHO for those instructions.

    The mill is wrapped up in storage until I get the workshop finished but I took some pictures of what I had assumed was the gear (I may be wrong, would love clarification) and the dividing head. unfortunately the taper is not in the box of bits but there are a lot of bolts off Hercus machines so hoping the bolts might be there.
