Rob, thanks. Mine is just a little Centec 2A. Pretty small capacity really but well made and could probably do some useful jobs, will need to have a think.  :scratch:

Hi Nick

The Centec is well made machine , do you have any cutters for it ? you never no it my come in handy one day , and if its not taking up to much room in your shop i would keep hold of it  :)

Well Lads i have made a bit more progress , the gear cutting is finished  :ddb: :ddb: :ddb: :ddb: but still lots to do .
Cutting the gear on the cross slide lead screw ,i was lucky the screw just went through the divding head spindle


I still have the wood ruff key to cut in the lead screw .

Next and last the clutch , as you can see the repair job on the clutch was not the best , the gears don't quite mess correctly  :scratch:
Photo shows them in the positon they would be in the apron

So i need to cut the 20T gear right up to the back of the cone , well 3mm ,1/8". from it ,and the gear needs to be longer as when i stripped it ,i found there had been a few washers added to take up the slack on the shaft .

So i decided i would have to use the shaper for the job . So i spent a few hours looking for my bracket i had made up to fit the dividing head to the shape , un-able to fined it i had to set about making up a new one  :bang: a quick bit of sawing and welding ,some 1/2" plate




The clutch set up for cutting the gear

A shot of the 3mm groove for the tool to run into at the end of the stroke

a few cut

The finished gear ,


i just have to finish the rest of the clutch and i can put the apron back together .

Cheers Rob

Just as an aside, when I first started cutting metal on big machines as a hobby.... I had no idea the amount of time I would spend 'getting ready' to cut metal. A bracket for the shaper to hold the RT, a mandrel to hold this casting etc etc etc an on it goes....

You did a lovely job on that table extension... nice welds...  :clap:

Rob

As usual, another outstanding job from your shop. I always look forward to seeing a new project from you because I know that I am going to see some first class work coming from your tools with your hands guiding them. I will be following along as it progresses.  :ddb: :ddb:

Cheers  :beer:

Hi Rob,

Yeah have got lots of cutters for the centec too.

That's an impressive bracket for the shaper - that would be a project in itself to me, the gear is even more impressive though, beautiful work.  :bow:

First rate work on that last gear, Rob.  Everything you've done here is top end. 
I always wonder what I'm going to see next when I check your latest post.  Never disappointed,
that's for sure.

Did you grind your own cutter for the gear on the shaper?

Hi Rob,
I've read this thread at least 5 times, it's on of my favorites on madmodder. Very impressive what your doing to this machine. Should make a very nice and accurate lathe by the time you get done with it. Look forward to more posts of how you progress with the repairs. Outstanding work!!!!!
