Hi, i have been given a non working CL350, I’ve been told the only thing that needs replacing is circuit board. Knowing most of these machines are all built using similar components, does the 350 share the same control board as the C3?
It may be a few weeks before it lands with me so I have time to do my research. From what I gather the lathe was bought around 2010, but has only see light use, till the board went bang.

I assume that you mean Clarke CL300 lathe, there are plenty of posts on here about these circuit boards, keep us posted. Regards Pat

I’ve been told it’s a CL350, an upgraded version to the 300, with larger motor and digital speed readout. This is what printed the question. The circuit board I think is the same used in the C3 with the 350W motor which I am told this lathe has.

Jon,

Looking in the most recent Machine Mart Catalogue they only sell the CL300, a search of the internet only brings up your post on this forum.

Well that’s one for the Google bots .Interesting, this is what posed my question, as I couldn’t find any info on a CL350. Did Clark sell a rebadged C3 at some point around 8years ago.

Jon,

I've had my CL500 for over ten years and the CL300 was around then, what I dont know is what it was a clone of.

The 300 I believe is very similar to the sieg C2 lathe in features and size. I am assuming if mine is a CL350 which I’m now having doubts, wether it is a clone of the Sieg C3 and if the parts are compatible especially the mother board.

The sorry looking state of the lathe.

Maybe if you could get a picture of the lathe it would help, you will need to read the previous posts which clearly explain the methods to test the electrics before doing anything else. Pat

Beat me to it, I don't recognise that lathe.

Must admiy ive never seen one…but clearly it exists. Unfortunately the manufacturers are prone to fitting different circuit boards depending on what they can source, your best bet it to call the machinemart dedicated parts centre and ask them to identify it, if you get the right chap they are very helpful. I have a lathe and a mill with blown circuit boards which I wont be repairing any time soon.

Having a closer look at your photo it does seem to be a lathe made up from other lathes bits, I would guess that the grey parts could be from an Amadeal CJ18 or similar and the yellow bits do indeed look as though they are from a CL300, some of the mechanical parts are interchangeable but the electrics are not. My CL300 before I sold it had a sticker on the circuit board showing the part number, could you get a photo of the circuit board? I am sure that it could be identified very quickly. Pat

I dont know if i can get another photo, feel cheeky to ask since its all for nowt. All I've been told is that the board says 2335. When I have a Google it sends me to arc Euro for a C3 lathe. After not getting a definative answer by googling all I can surmise is that the board is the same as the C3 but just wanted to double check if someone knew for certain on here.

Is this any good, the picture has a supplier name https://www.google.co.uk/search?q=PCB+2335&rlz=1C1CHBF_en-GBGB780GB781&tbm=isch&source=iu&ictx=1&fir=ZRVvTlpLU0gCWM%253A%252ClviXj5cmQE7XHM%252C_&usg=__AI8VIwvOcycXU64TYH3tjfEZ2Bg%3D&sa=X&ved=0ahUKEwiG37H4q6_aAhUHxoMKHSv_DLEQ9QEIODAD#imgrc=ZRVvTlpLU0gCWM:

If you enter CL300 into the search keyword box at the top of the column then everything that you need to know is in there going back 9 years or so, I used it myself and found it very helpful. Pat

The 2335 number I suspect could be the Sieg XMT 2335 board which is available from Arc.

This board features a pair of thyristors in a bridge arrangement to provide the dc drive to the motor. These boards are more reliable than the earlier boards used on the CL300 machines that featured a pair of mosfets to drive the motor, would fail at the drop of a hat…

The Lathe is (almost certainly) a Chester Conquest Super, essentially a SIEG C3 (not to be confused with the SC3)

It isn't the Clarke badged version.

400W brushed motor, so a C3 controller board (NOT an SC3 brushless controller board) should work.

Hi Neil, I'll ask if the cover has a "C" in the castle on the front electronics box, as that seems to be the only desernable difference. The tailstock design is different have these changed much over time?

Yes, you have the old nut-fixed tailstock, the Chester photo shows the lever locking one (lever just visible at the back)

Presumably no-one finds it interesting that Clarke uses the 'brand' Metalworker

… as does Bellmex, for a 350W lathe of this style.

ok thanks Neil, So its a chester mini lathe then.

Is it easy to change that to a quick release such as using a nut with a handle attached, similar to the toolpost. or is it better to look at redesigning and make a camlock type?

As i said i'm doing my research, I found a wonderful website which the link is on my phone, which shows a lot of the mods that can be done with these lathes. Will post the link later on.

Once i have my hands on it i will be checking for wear and making any minor improvements to the bed. I have seen these turned into nice capable machines, which would be a benefit. As the ML4 is definately on last legs before some major refit is required.

Sorry Michael missed your post.

Is metalworker a brand name to another company? I have never heard of this Bellmex company.

Jon,

I know nothing of Bellmex either

I stumbled across that listing when searching for 'CL350 lathe'

Noticing the 'Metalworker' branding, I thought there may be some association with Clarke

… but it's circumstantial evidence at best.
