Clarke CL430 Metal Lathe

[Les Jones 1Participant @lesjones1]

If you turn the manual feed handle at about the same speed as it rotated when set to auto does the saddle move at about the same speed as it was moving in auto ?

[Brian Davies 6Participant @briandavies6]

Hi Les, yes it does go about same speed

[Les Jones 1Participant @lesjones1]

With the lathe set to auto feed rotate the chuck exactly 10 turns by hand and measure how far the saddle has moved. Check that it moves the amount expected from the tables on page 21 of the manual for the way you have the chagewheels set up. If it is less than the expected movement from the tables then a gear is probably slipping on a shaft. (Possibly the gearing controlled by the two speed lever. Item 30 on page 14 of the manual.) If it moves the amount expected from the table then there is nothing wrong with your lathe.

Hi , I have put new belts on set to what I think is slowest speed then done a speed travel test it took 45 seconds to travel 3 inches it also traveled under load , it seems ok but fingers crossed

[mick70Participant @mick70]

it does move slower in auto.

is it geared for standard use?

mine always did never had prob with it.

where are you?

Hi Mick I’m in Pontefract West Yorkshire

[martin perman 1Participant @martinperman1]

Brian,

Dont forget that the lever half way up the headstock increases or decreases by half the feed rate of the leadscrew.

Mick could I ask a favour ,I have removed the belt pulley of the motor and like nob I have forgot which way it go back on ,could you send me a picture of yours please ,I have got it going now ,I tested it on full speed and the saddle fly over from tail to head stock in a flash but I’m struggling get it back to run at slowest speed I have 2 sets of belts 1 set is new but it’s as if the belts are to small but they are genuine belts

Thanks Brian ( should have said in early posts that I have had this lathe quite a while but never used it but now I would like to learn ,I have learnt a lot in the last few days )

[mick70Participant @mick70]

hi mine is in storage since events meant i lost workshop so can't do pic.

but on the pulley is a small one behind the big one that faces motor.

have you got right manual for it?

a lot were sold with wrong pulley diagrams.

[mick70Participant @mick70]

if you still stuck could come over but not this week.

i'm at jct26 m62

[Brian Davies 6Participant @briandavies6]

Thanks Mick I can work from that , we have had a big clear out at Home and I can’t find manual anywhere but I have a downloaded one and assuming I have the right one ,thanks again mate

[Brian Davies 6Participant @briandavies6]

Thanks for the offer mate I’m at junction 31 or 32 m62 ,I will let you know how it goes

[mick70Participant @mick70]

no probs

[Brian Davies 6Participant @briandavies6]

Well I have fixed it and it runs perfectly ,don’t ask me what was wrong with it cos I don’t know ,I took the advise of a chap on here and strip it down every screw nut bolt I could find cleaned and put it back together eventually ,if nothing else comes out of this I have learnt a lot about my lathe it’s workings ect and it’s had a good clean ,all I need to do now is replace the oil level sight glass but that had to be ordered 10 day delivery and make a pin for the collar on lead screw ,now I think it’s about time I started to use the lathe to make things instead of repairs for other things ,thanks for all the help tips and advise

Whoopee!

Good experience, and confidence building.

Maybe something in the drive train was slack

Now you can really start to enjoy yourself and reap a LOAD of satisfaction from what you can now make, mend or improve.

You may well gain lots of new friends "Can you just?". Again, the pleasure of turning a basket case into something that works, and will probably be more durable and reliable than the original.

Stating the blindingly obvious, the set up of the belts or change gears will alter the rate of auto travel.

Go for it!

A big whoopee, would have loved to seen the smile on my face when I put it all back together and it worked , every nut bolt cog belt etc removed clean and put back ,new belts on, now I know how my lathe is built and understand how it works ,it’s now back to how it was as it left the factory ,don’t really know what was up with it maybe something was slack out of adjustment or stuck but I now know how to deal with it in future , I have not touched set up for screw cutting YET ,just got to replace oil when new sight glass arrives , now I will start on a few simple projects and as I have not used the screw set up yet I think 1st project will be a fancy die holder with morse taper

the manual is available as a free pdf from machinemart.

Being a cautious, if not scaredy cat, I would suggest leaving cutting Morse tapers until you are more familiar with operating the machine. (Is the Tailstock correctly aligned with the Headstock? If not you are likely to cut tapers, whether you want them or not!)

Making a Centre Height Gauge will time well spent, allowing tools to be set up more quickly.

Next, perhaps, make up a Tangential Tool Holder, and sharpening jig, to use HSS toolbits.

Then you can make some of the tools that you want.

And then the world will start to be your oyster, and you can enter into the spooky world of thread cutting, although for a lot of what we do, Taps and Dies will suffice.
