9x20 Lathe repair....

(1/3) > >>

Divided he ad:
Also known as.... "Wondering why the drive belt fell off!!?"


I had a few hours to myself tonight, home early from work and no pool, snooker or cars to fix :thumbup:


So I thought I'd have a go at my finger engine designs..... Not if Murphy or Sod have anything to do with it!!!


My main toothed drive belt fell of my lathe  :scratch:  
After a minor investigation it was very obvious why..... My clutched main drive sprocket was wobbling like a jelly :jaw:


After a quick strip down it was clear why,


The spring loaded oil way (little brass bit next to the circlips and the washer) had a big lump of @%$! in it and had not allowed the oil to pass through to the rear of the assembly.... Can we all say "dry bearings are bad"?

A 14mm ID bush..... For the 11.95mm shaft!




I removed the bush with a few small taps using a drift through from the other side.


Then thought to myself "how the hell am I gonna make a new one?!"  

I thought about the mill and then was struck by a bolt of obviousness.... Use the lathe!





Not the 9x20.... This one  :D  (peatol/taig lathe)



My first personal lathe, he's been in storage for nearly 2 years..... Still purrs like a kitten  :)


So a bronze bush was made..... These little lathes are fun and super accurate I just had to remember how to work it!!



The difference between the two....





One final issue, getting the clutch mechanism back together.... compressing 5 springs and fitting a circlip.....

Well, a little thought and 5 min's later I had it sussed, a mini spring compressor. Hacked out of a piece of ali box section, it worked a treat  :thumbup:









All back together so that I can use it when next I get a few hour to myself....Not for the rest of this week, Pool trophy night, a landrover Diff' to replace, a gearbox out and in on a Vectra and a second hand door to fit for a foreigner on sunday!!  

I think I'll be lucky enough to get some rest let alone some "me time" ::)




Let this be a lesson, when you hear a squeek..... Investigate, don't leave it for a few months!!!!   :doh:

Hey nice fix Ralph.  :dremel:  :thumbup:

My 9 X 20 keeps throwing the skinny drive belt off because of the idler wheel that isn't running straight. Didn't know I'd used the lathe that much to wear it out.

My fix? Well I'm going to go for a drive out of a tread mill one of these days.  ::)

Stilldrillin:
Very nicely fixed, (and shown) Ralph!  :thumbup:

Good fix there Ralph.

As you know, if you get stuck, my shop is only is only a short drive away.

My heart sank when I realised it was the bush, not because of the fix required but because I'd set myself up to do some work on my projects  ::)

Still, fixed now though  :)


Glad you liked the little(?) post on this gents.

John, you were one of the thought processes.... But when the Peatol came into my head I had it sorted  :thumbup:


Bernd, from what I remember reading the tread mill motor is quite a common conversion over there.... Must be something about freely available treadmill bits?


David, it's remembering to take the pictures when your head is on the job and then not filling the post with them all (There's another 12 or so!!) that's the hard part  :thumbup:




Right, back on me head!  (obscure statement of the week?)






Ralph.
