Cheers Rob

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.

Rob.Wilson · « **Reply #56 on:** March 02, 2010, 03:00:16 PM »

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

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

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

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...

Darren · « **Reply #60 on:** March 02, 2010, 05:56:02 PM »

Lovely job as usual Rob, I'm always finding myself in awe of your many tallents ..... but please answer me this... where is the swarf, how come you don't have any

dsquire · « **Reply #61 on:** March 02, 2010, 07:13:06 PM »

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.

Cheers

Just went back and read this thread again. Realized I never said anything... holy cr@p Rob... some serious skills there. Great reading and great pictures.

NickG · « **Reply #63 on:** March 04, 2010, 07:24:23 AM »

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.

Just, wow.

I notice there's a lot of these

in this thread. Well, here's a few more from me:

I hope one day to be able to produce work that looks as crisp as yours.

Dean W · « **Reply #65 on:** March 05, 2010, 02:03:04 AM »

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?

Dean

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!!!!!

The lathe has been on hold for the passed mounth or so ,, i have been working on the 626 mill and Boxford shaper , just need to do the wiring on both, then i may leave the lathe for a few weeks, as i have been repairing machines for what seems forever ,,,,,,,,i will probably dust of one of my engine projects

Cheers Rob
