Don't try this at home.

[DavidA]

Thought I'd move my lathe across from it's base to a table top.

Didn't quite make it.




OOPS.

Dave.

Oh, BUGGA!    

As we say around here..........   

I'd stick it straight back together with sleevelock, or something similar. Though someone else probably has a better idea....... 

Good luck with the repairs Dave!

Hi Dave,
Why not just make a thick sleeve to go over the broken bits to hold them together. A dollop of JB weld and a few strategically spaced screws will make it as good as new.
You could get it welded but you would have to consider pre and post welding heat treatment to prevent distortion or cracking. You might also loose alignment of the bits if welded. All in all, better if you go the sleeving way. You might have to get someone with a decent size mill to use a back to front cutter in a boring head to machine the casting to round first, if it is "as cast".
The broken handle should be no problem to fix, just drill and tap for a short length of all thread.
Don't sit and mope, fix it!!
Good luck,
Ned
PS Re. dropping things, easily done isn't it! I had a similar problem with the leadscrew handwheel on my Myford, soon fixed though with no drama.

I was going to suggest brazing the parts, but Ned's idea is better.  If you make a sleeve and a dial for the handle it'll actually be an improvement not a repair

How long is that broken teardrop? I have one or two here I could send you if they are the same size (just drill out the old broken piece and thread in a replacement).

u have all the  parts why not cast a new one..      hate when that happens

[DavidA]

Yes,  I do recall saying "Gosh,  isn't that annoying" as the tail end of the lathe skidded down and smashed.

I had already decided on a sleeve type repair. Similar to Ned's idea.  The idea is to clean up the areas involved around the broken bit.  then after degreasing carefully I'll use some kind of metal glue to fix the broken piece back into place using a jubilee clip to keep it in place until it sets.
Next, carefully file the last couple of inch nice and round and make up a collar (with two new location holes for the grubscrews) and araldite it over the break.
Fortunately I can turn up the collar without use of the tailstock.
Should work well.

I'll post a few pics of the progress.

That's what we like to see!       It's called   

Break something. (On purpose, if you like)........ Think about it.    Post the solution on here! 

You're learning very quickly.

All that horrible silver paint removed.  The break cleaned up and the bits glued back together.

BillTodd,

Missed this bit earlier.  The teardrop had enough material to be threaded.  But it seems that the whole hand thing is one casting.  So I am going to braze it back on.
Thanks for the offer.

Dave.

[Jonny]

I doubt brazing will last long, sorry.

Tried silver solder on an ML7 tail stock after some abuse, that didnt last long either. When you drill it will be trying to break out towards the rear being load bearing.
V it out and use proper cast arc rods, trouble is it will distort. Heat up first then weld, allow to cool over several hours.

Look on the bright side it might give you cause for a new lathe.

[DavidA]

Jonny,

I'm only going to braze the little handle back on.  How much pressure do you think I am going to put on my tailstock centre ?

...Look on the bright side it might give you cause for a new lathe...

Spend money !!!!!  now then lad,  we'll have non of that kind of language here.

Dave.

[DavidA]

First select material,
A bit of old scaffold tube should do it.


Then machine  it to size.  That's not rust,  it's preservative.


Next,  use trusty grinderette to reduce tailstock outer diameter to fit.  Hoping that the glue will hold.


All ready for sleeve to be glued on using an epoxy metal.

I've just put some of my stuff on photobucket.  How do I link the pics from there  to here ?

I'm trying to avoid loading up the madmodder.net server.

This will flash copied...... Paste into your posting, as you write.

Much easier to do than to explain!

Dave,

Thanks,  I'll give it a try now.

Seems to work.  I've edited post No 11 above.  But can I get it to display the picture and not just the link ?

It's the HTML code, you need. The third one down!


Silly old fool.......

Any advance on 'it's the last one'

Going,  going,  gone.

I'm off to change them.

Looks like Rob beat me to it.

Thanks for that.

Some of you may have noticed that I'm turning the sleeve on a different machine to the broken one.

This is my Rufold.

It's another that has no identification.  And as it is a well used 'built to a price' machine I know it as the Rufold.  Simply because it is a rough old lathe.

But it still works well enough to do lots of jobs.

Dave.

[DavidA]

So,  all done.  Just need to fit it and then re - align the centre.

First completed job of 2011.




How do you like the new colour scheme ?  Almost Midland Red.

Dave.

[Stilldrillin]

Dave.
That looks really nice. Blummin well done! 


"Rufold", because...... Now, I really like that! Sounds like me, but much more efficient.......

Hi Dave,
As an old mate of mine would say "just like a store bought one".

PS it's meant as a compliment, by the way.
