    Hi All just joined your forum. My Hercus is a C model serial no.cr14271 Dont know year of man. maybe you can help with this. At the moment I am working out how to use this as I am a retired carpenter looking for somthing different to spend some time on. I havent done much metal machining. I have a small farm and like to maintain my own machinery. I probably wont post often but hope to learn by other postings

    SORRY I should have said this in my first post but if anyone is interested I have copy of Hercus Text book of turning second edition 1970 It is in PDF format. I think it covers all models of 9" lathe If any one needs one I will email to them.

    Hi Les,

    According to our records, your Hercus was made in 1972, making it about 27 years old.

    I'm sure Bitza 500 will ask for additional info etc to complete his records, so I will leave it up to him.

    Congratulations,

    Ken

    Default Congratulations Les you are No 50

    Hi Les, Congratulations as you are the 50th person to Register their lathe and Welcome to a distinguished group of Hercus fanatics.
    If you have any problems, just ask a question and if this lot cannot help well you are in trouble

    We have now 50 heads and probably hundreds of years experience between the lot of us
    we have 75% doing either rebuilds or like Gene's and Ken's Lathe a Musuem piece as a lot are restoring to their original condition

    If you have any problems or need any parts let us know as I have THE HIPPY a 70+ parts maker with Hercus gears and other parts I do the wrecing to keep the group with parts to finish their machine off
    So if you need parts email me at home otherwise it clogs up the Forum
    Congratulations and Welcome again

    all the best Derek [email protected]

    Hi guys, as a new owner of a Hercus AR on Vancouver Island in Canada I was really pleased to come across this list. I look forward to learning a lot from browsing your posts as I'm new to metalworking, and the Hercus is pretty much unknown in these parts. Funny though, Hercus must have shipped a bunch of the machines to western Canada at some point because there are at least 2 more here on the Island and another over in Vancouver.

    Anyway, mine is AR8312 V and has the RGE-in-an-oval stamped on the ways next to the serial number.

    Default A fourth canadian hercus

    Hi Greg, and welcome and congratulations on owning a Hercus the fourth one in Canada so far
    We have 2 other owners in Canada but why have 1 Hercus when you can have as much fun with 2 RIGHT Al???

    So far we have not discovered the reasoning as to why Canada Schools chose the Hercus in Australia to the South Bend in that other Country but am still trying to find out
    As In the very early years the Original MAN Fred Hercus offered British Migrants a cheaper price on a Hercus if they left their old lathe back in England

    How Canada was won over I have yet to find out but can you enlighten me on how or where you obtained the old girl from, as not having much information as to why the Hercus ended in Canada and not yet finding the right website to ask in the Education Department over there if anybody can still remember

    Main things between Hercus and South Bend is the Angle of the gears which I have been trying to discover the original facts
    As we know Fred was not impressed with the Gears on the South Bend which had a Pressure angle of 14.5 Fred increased the hercus to 20PA which made a stronger gear
    The one point if buying American parts
    All the gears interchange but when combined the gear train is noisier due to the 2 different angles and the South bend gear will wear out quicker than normal


    But welcome we now have 51 heads + more than able minds who will give you the best advice as to any question you want to ask as that is why I started this as I had a hercus and no one to ask well we all have our little prides of joy and we hope to maybe see a picture of the lathe and any History retaining to the lathe

    As for the RGE in a semi Circle that is the approval stamp from the person who tested the machine
    So Welcome to the group and ask all you like
    all the best Derek

    Default Hi fro PG Greg

    Hi Greg, Nice to have another "local" Hercus guy here! I inherited a Hercus a few years ago and recently bought a second one from a guy here in Pr. George. It was more like "rescued" one from the guy......some people shouldn't own machines!! I'm just putting all the pieces back together after a complete strip n paint with new bearings etc. Currently working on making some new gears ro replace the 5 with broken teeth.
    Would love to see some pics of yours, I guess it's original color would have been battleship grey? My first machine is from the 70's and is green but the one I just bought is older, early 60's, with the grey. Doing the restoration I wanted to match the original colors. Can you tell me about colors where the Hercus name is cast in at the tail stock end, is it all grey or is there some hi-lite color used?
    What kind of shape is yours in? What are your plans for it, will it be a workhorse or a putterers (is that a real word? lol) toy?
    I'm not sure what I will do with this second Hercus when it's done as space in the home shop is becoming a premium. It has the a factory cabinet which my doesn't but is the short bed (same as yours) but the 1at one is and 'ARL' which has a longer bed.
    Well enuf for now, look forward to hearing more from ya Greg.

    Remember if the ID exceeds the OD the hole will be on the outside!

    Default hercus 'O' mill owner

    Can you add my name to the list. I have a Hercus "O" milling machine with serial number OLM-478. It is complete with horizontal and vertical attachments and came with the dividing head. It is a metric machine and in good order. Currently getting mods to include star / delta wiring to motor and then a VSD for single phase input

    Default Another mill

    Hi mg, and welcome you being Number 52 on our slowly expanding list of Hercus owners
    You are the 4th Mill owner and probably half the owners would love to have a old Hercus Mill ME included
    Can you give us any history of the machine or what you use it mainly for pleasure or work as many a Hercus is still being used in the Machine shops of Australia

    How do you go chasing parts as with few on our list means that parts might be a bit scarce ????
    If you could post a picture of the old girl to show her off would be appreciated

    all the best and welcome again Derek

    Default Hercus 'O' Mill - #52 on the Hercus list of stars

    Hello Derek,
    From what I understand it was sold ne into a QLD State School and stayed there until a workshop refurbishment when it was upgraded. I purchased it from a dealer. The serial number OLM-478, which is stamped on just about everything indicates it is late 70's early 80's and a metric machine. The long travel leadscrew was quite damaged when I got it but has now been repaired. The machine has original paint and transfers and little if any wear on the slides. It is in my home workshop, current project is a clock and will be followed by a steam engine of some kind. I have a lathe and am a toolmaker by trade so I tend to make the unique stuff, even if it is a reverse engineer and make by others. So far, I have not had to send any work out but time is always an issue. I have a photo in another thread started by surfinev on his mill purchase. I will put an up to date photo in a few weeks on this thread when the mill is complete with motor and VSD.
    regards
    MG

    Default The vsd

    Hi mg, these VSD units are starting to become a common thing what are your experiences with making or buying parts to build or anything that can give us 240volt owners a insight to upgrade to 3 phase as the 3 lathes I have wrecked for selling spares all were 3 phase and as shortly the garage may get a few more added machines like 2 big lathes and a Milling Machine which I will get to see tommorow but any info on the Mills and the VSD units would be gladly welcome

    all the best Derek

    Default VSD things to watch

    Firstly, I am no electrical guru but the 3ph motor I have is star wound. First step is I am having it changed to delta wound and that will allow the VSD to work and convert the 240 input to 415 output. Some of the larger 3ph motors are star and delta wound to reduce starting current draw. The modification I am told is relatively easy to do if you know what you are doing. But it seems to be a case of if you know what you are doing you do not need to ask anyone. I would suggest in the interest of safety, that the work be carried out by a licenced electrical repairer, the cost is between $70-$100. The VSD you purchase needs to be sized to the motor and one size does not fit all. I will most probably use a Allan Bradley / Rockwell unit as I have access to support from some of my controls buddies. Do your homework with the supplier, look up the internet for local representatives. Buying off flea bay may not be the best value option, be careful. Again, unless you are licenced sparky, you then need to change the wiring on the machine and get a certificate of electrical compliance as I will be doing. I have access to a very good ex SEC electrical fitter who has the smarts to do more than just change light fittings. Always amend the wiring diagram to reflect any changes. Making mechanical parts are another matter, I will discuss in another post.

    Default A girl electrician??????????????

    Hi mg, My eldest daughter who is 26 is a fully qualified Sparky but amazingly she can do 3 phase blindfolded
    as she has only done 3 phase repair work for her Company she works for and only did 240 volt at trade school, and I asked her about the VSD and it was like talking another language My big mate his neighbour is the same as he just got retrenched after 22years and knows zilch about wiring 240 Volts or these VSD units as I am wondering if there is such a unit that can run 3-4 machines out of 1 VSD unit ???
    I have done 240 volts stuff for over 30 years but asa the lathes I have been buying to strip for parts they are all 3 phase ,plus as a Milling Machine is on the way and another bigger lathe,I have been asking about these units
    The Majority said just get 3phase from the street but cost wise is a problem for me at any time
    Can you ask you Electrical mates about just 1 VSD unit to run 3-4 machines as 3 phase is a foreign language to me and not had much luck in finding anything that says yes or No to a multi connected VSD

    all the best Derek

    Default one to do all ??

    Derek,
    The short answer is yes and also no. For background, the applications that I have worked with tend to have either -

    a) one drive for each motor such as steel rolling mills and moving industrial plant

    b) one drive for a number of identical motors that need control at the same time such as an extremely large gantry crane.

    The most number of drives and motors in combination that I have had to manage the engineering of is 120 drives for 120 motors and they all needed to talk to each other. The most number of motors with one drive has been 8 and they were all identical and all operated at the same time. My understanding is that you don't mix motor sizes with a common drive and that they all work at the same time, not individually or somewhere in between.

    Unfortunately there is no cheap way to do it, a VSD for a .37kw will start at about $240 + any mods to include delta wiring if it is not star and delta. A VSD for drives over 100kw can be up to$25k!!! Consider a single small VSD for each motor, it may be the cheapest option for the fractional sizes on most domestic scale equipment. I know of others who have found a 3ph generator is the best way to go and forget the single phase mods or wiring from the street.

    You need to engineer the most cost effective solution for you and what you have. I am not being cruel but you will have to spend money somewhere and time to work out what is best and I am not sure the required detail is easy to transfer to an interest group such as this forum. I have seen the 'cheap' capacitor start mods (where the phases are shifted) that do nothing but introduce vibration and are simply not worth the effort and potential damage to the workpiece.

    So in summary, I would strongly suggest unless you are able to engineer a solution it is highly unlikely that a single VSD to service many possible options would be cost competitive relative to a number of smaller lower cost VSD's used as individual drives. I would not mix, match or select a drive without using an applications specialist who knows the characteristics of the motors and possible drives.
    regards
    MG

    Anyone got an idea how much a single to 3 phase VSD for use on the 9" would cost?
