quickchange toolpost mod

[Mr blindbird]

Hi all,
Allready when i introduced myself,there were peeps anctious to see what i was gonne make first on the lathe...here it is;
quickchange toolpost mod
The toolpost that i bought sat only on a small diameter,not having enough support,it would make the cuttingbit wanting to slide under my piece when trying to part something  
quickchange toolpost mod
So i made a new rod with threads;

Connected it to the original nut and secured them with an internal hex bolt M5;
quickchange toolpost mod
Drilled 4 holes in the sled and spacer which i needed to make the toolpost stand high enough to be able to reach center with all possible tools,slipt the spacer over the new rod and secured it with 4 bolts M5(I made absolutely sure i wouldnt drill anywhere in the guides of the sled first);

Made a spacer so the handle to fasten the motherblock would face the right direction when tight;

Assembled everything and there!! a nice tight sitting toolpost;

Hope to be a help for anyone else with this.

A worth while Mod'.... You gotta have your tool held ridgidly! 



Looks like you're getting to grips with the new machinery too Danny?   



As Stew said..... What's next?  (We always ask that  )






Ralph.

P.S. You certainly got the picture thing sorted 

[Stilldrillin]

Very nicely done Danny!

Hi Danny

Sorry for the abrupt sign off.

I ment to ask if you screw cut those threads in the rod, very nicely done  threading up to a corner is never easy, looking forward to your next project.

Cheers

[Mr blindbird]

Yes,i did cut them,even in a strange way;backwards with an inside threadingtool mounted upside down
But i have to say;there is a button on the lathe that makes the engine spin a short way,that made it easyer to get back to the narrow groove,realy great help as i tend to cut my threads keeping the halfnuts closed to go forth and backworth on the same thread.

It was still in my fingers after all this time

Hi Danny

I would never have thought of cutting threads like that, working back from the shoulder, thanks for showing that ones filed away for future use.

 


Cheers

[Mr blindbird]

Glad to bring in some light but if you do it like this in the future...make ABSOLUTELY SURE your head is 100 percent clear because,you have to keep on mind;you have to start the chuck turning the other way to...one mistake and you can end up launching the threadingtool into the piece with a ruined work and broken threadcutter following...wouldnt wanne have that when you allready spend some hours on the piece right?

[Darren]

Certainly wouldn't.....

Interesting idea though. Did you make the plate as well.

I was thinking that this was maybe the only bit you made but it seems not.....

[John Hill]

Excellent example of work on that shaft Danny!

I too have a 'jog'  button but I am careful of using it because every 'start' puts a strain on the motor especially the starting capacitor and mine has already failed once.  It is a Chinese lathe.

[Mr blindbird]

Yes i did,i first made it to thicknes on the lathe,after that,because i dont have a millingmachine yet,i just cut it off with a small anglegrinder,folowing the lines i drew on it on the back when placed on the sled,so it would have the perfect(near) fit,then took off the burs with a lime and drilled the holes when fixed to the sled so they would fit perfect with the bolts.
And Thx for the warning about the jogg button john hill ,i'll keep it in mind next time,didnt know abouth the starter thingy,i just was pushing away happely.
The last thing i want is a lathe that breakes down in the midle of a project,would be a hairpulling event then

I think Bogs has just replaced his motor on a similar lathe due to failing caps.

Though I imagine it would be easy enough to replace the caps with better ones if/when they fail.

[Brass_Machine]

Nice work there Danny.

  Nice work Danny.  I too have used upside down and backwards to thread from a sholder and , Yes, your head must be in the right place or the next loud noise you hear will be expensive.  The threaded post looks very good and on top of that is does its entended job and, that makes life worth living. Now that it is finished, go to the pub and

Nice bit of fabrication all round me thinks! 

It's gonna be fun seeing what you produce when you've got the mill' and your 'shop sorted Danny 




Cliff,

I am a  nut

Shouldn't that be bean?
