Record CL3 Help please

[johnny5]

Hi,
Since my move my CL3 does not turn at its maximum speed when turned on, feels restricted .
When i drop down one speed it works fine and after 5 minutes i change speed back to full and it works fine ??

Any help please , it appears to be running square and true but for some reason wont run at full speed initially.

i would check the head bearing is it lubricated or is it running to tight starting in a lower speed has more torque so it sounds as if the bearing is running tight

Thanks, will have a look in the morning. The lathe has been idle for 2 months ? could that be an issue. I thought maybe it could be the capacitor.

 

[Alanp]

being idle shouldn't be an issue but the bearing may have dried out which would be an issue

Is it making more noise than normal Johnny

 

[Jimjam66]

If it were the capacitor it wouldn't start at all, would be my guess. Tight bearing sounds feasible - did you oil the head bearing after the layoff? CL3's like a drop of oil pretty much every day.

When i start up initially in top gear yes, but then returns to normal when i drop a gear and back to normal when i put it back into top gear.
Yes i did oil it but only 4 drops before starting. will give it a good oiling tomorrow and start up in lower gear and un it for a while.

 

[GeordieB]

oil ya bearing anyways and check your belt isn,t to tight my bandsaw wont run if belts to tight

You will know when the head stock gets hot real quick if the bearings are ok ( or need oiling ) but also turning it by hand before you start there is a preload on bearings as a rule to keep them in place and to avoid shaft travel when you cut with the lathe lots of stresses in the lathe. A capacitor in a single phase motor can be for capacitor start or capacitor run. If its for starting and is faulty turning by hand will allow the motor to run under no load and will hum. By now in the scheme of things you will have a solution trust you do. Even in my drill press I use an overkill sized motor a one HP.. 2 hp in my VL150 three phase.

Had a look this morning. Noticed that the tailstock was out of alignment by 5 mm to the headstock????
this was putting pressure on the bearing and making it slow to start under high speed lower torque.
Lucky i have 2 CL3 lathes and just swapped the tailstock over to the one i use regular and now it works, however the lathe still has to be started with no tailstock pressure on the bearing and once started only then can i tighten the tailstock to the blanks and start to turn.

How can the tailstock be out of alignment ??, when i tightened banjo the tailstock moved out of alignment even more, putting more presssure on the bearing.

I assume the lathe is sitting flat?
has one of the bars come lose?

did u dismantle it to move it? if so did you put bars back in same place?
slacken a bar and give it a twist...can u do this on the cl3?

may be a slightly bent bar...could have been like this from new I guess
but rotated the correct way might possibly fix this

Steve

if you lay 2 straight edges across the bars one each end
can you look down them from the end and see if that are lvel

a bit like using winding sticks

 

[johnny5]

Checked the lathe again , the motor is now sticking even under no pressure, give it half a turn manually and then it starts, ??
Will give record a ring in the morning, methinks a new motor is needed,
Still got my old blue CL3 that works well,
Been looking at a small DML305 recently , this may make the decision easier to make..

 

[Twister]

more likely the bearings where they have been under sideways pressure

I don't have a record lathe and have little experience of them. A 5 mm misalignment is a large discrepancy. Some lathes are "handed" in that the banjo clamp is sided and also some castings are offset and clearly reversing it could cause a misalignment. My other concern is that the extra stress suffered by the head stock may have flat spotted the bearings. You should be able to diagnose this by hand rotation of the stock if the bearings are damaged I would expect you to feel a less than smooth rotation. A simple way of truing up the head stock and tail stock is to mount chucks on each insert a tool steel rod or even true drill bit in the head stock chuck and attempt to grip the other end with the tail stock chuck if successful the lathe will be reasonable true albeit fine adjustment will probably be needed. Hope this helps

Fit a dead centre in the head and tail stock for alignment check bring the two points close together using a thinnish feeler guage between bring the points softly together an accurate idea of whats happening in 360 degrees is then obvious. Now this is only the first of a few things to do to check your lathe. The main problem so far remains to be solved. If you have a metal lathe user consult with them these things are far more critical for them and close attention for a metal worker is vital.

Sloppy tail stocks in wood lathes are often the norm unfortunately as they slide down the bed and you lock them in position another chance of misalignment. I always felt using a metal lathe before a wood lathe can be a distinct help cause wood lathes are dearer than metal lathes as far as quality goes the same applies.

Have success mate look for friendly help belonging to a wood group most all members have been through these things and the cure is at hand.

Take the bearing out of the equation - try running the motor without the belt on, make sure it spins up ok.

I had a problem with my bearing when I first got my lathe - the shoulder of the spindle didn't extend past the end of the bearing, and the thread saver was binding on the end of the bearing. This was a manufacturing fault, as the spindle shoulder couldn't actually fit through the hole in the bearing! Record were great, sent me a complete bearing kit. It was annoying though!

 

[johnny5]

Spoke to Record, New capacitor arrived just now, fitted and all working fine again.
Swapped tail stocks over and both are in allignment ??
Mix and match got 2 blue and green lathes now

Great news simplifies problems finding the solution ends all conjecture life goes on. Cheers Johnny.
