|Thread: colcehster bantam 1600 mk2|
hi all, so i got a spare hour yday (time is precious with 2 kids under 10 and full time job!)
i removed the top gear - which came away without too much hassle. the splined sleeve is a completely different matter. it will not come away. i modified a bearing pullers and i got maybe 1mm of movement but there was a lot of pressure on the pullers. i wasnt sure if this was normal so i didnt force it anymore.
can anyone who may have removed one before say if this is normal or should i apply enough force to pull it off?
i have attached a pic with the top gear off. you can see the top of the shear pin clearly.
im going to be in work until wednesday so hopefully by thursday i will remove the gear and have a better look at the shear pin, i really hope it is something simple like that...knowing my luck it is bunched
here are some pics of my bantam :-
Firstly, thanks to everyone for the replies, its good to know there is help.
right back to business - Tony,
When you switch your high / low switch does the third rod switch then allow you to run in the opposite direction ? no it still only runs in the direction which is set by the high / low switch (low is forward, high is reverse) and the apron lever will only work when you pull it up, pushing it down does nothing. i will post some pictures in the morning.
i do have a photocopied manual but it is only numbered to page 23 - after that it goes into a parts manual that is not labeled.
When you say "when i set the leadscrew lever to either forward, reverse or neutral it makes no difference." do you mean that the leadscrew does not rotate in any of the three positions or do you mean that the saddle does not move. i mean that the leadscrew doesnt move at all in forward or reverse but when i move the leadscrew selector on the headstock i do feel it 'click' into place, i can feel it mesh with gears in the box. Having read all of your replies it sounds like for whatever reason the powertrain to the leadscrew/screw cutting box has been disconnected. I will have a look tomorrow. I will also take some pictures.
I am not overly familiar with lathes or the electrical gear,,,,this is my second lathe, my first is an ML7 with imperial box. a nice little machine but as I am into building model steam traction engines I just find it harder to make some parts that I was hoping the colchester would make easier....
I have just broken a long time rule of mine and im afraid ive paid the price - i bought a lathe on the internet without viewing it first.
when i got it delivered i set it up and plugged it in - the seller told me it was single phase and that is one of the reasons i bought it. Plus i have felt that a bantam mk2 is the perfect size for my requirements and space available.
when i lift the apron lever up the chuck turns. however when i push it down nothing happens. as you know the apron lever should dictate the spindle direction. when i set the leadscrew lever to either forward, reverse or neutral it makes no difference. I have found out that the high/low switch is now infact set to control the spindle direction. low being forward and high being reverse.
it is a good lathe otherwise not too much wear on the beds and the spindle is relatively quiet. BUT to me this is a big issue as i really need to use the automatic feed / threading capabilities.
has anybody any ideas how i could fix this or do you think it is now simply a gearbox - less lathe??
any help appreciated
