Thread: Propane gas adapter

Have you tried Camping Gaz bottles ?

Thread: Tool steel - Beginners guide ?
09/12/2019 00:04:10

Hi Dave

You could try making a key from EN16T, tough enough without hardening.


Thread: Micro Mill

Hi Paul, like you say could be a very low cost solution at £30 will certainly get you away from the DC controller problems.


08/12/2019 22:18:37

Hi Paul, if you have had many problems with the motor perhaps you are expecting too much from the power available, going smaller will make the situation worse, if replacing the motor and can use a larger physical size go for a .37kW but you then have to consider the strength of the drive system from motor to spindle.


Thread: Problems VFD with 3 phase motor - keeps tripping fuse
06/12/2019 13:59:45

Although all cable ID's are shrouded I agree looks like connected for 400v working, remove links and fit top to bottom as pictured.

What rating and type is the mcb ?


06/12/2019 13:28:55

Can you confirm if it is a fuse rupturing or an mcb tripping, also state size and type.

The rating of the fuse or mcb could be too low for the load or the motor may have an line to earth fault.

If supply is 240v to the VFD you will as a rule be getting 220v 3 phase output so your motor needs to be connected in Delta form for the lower voltage to function at rated power.


Thread: Help re: motor & Dewhurst switch wiring for Boxford lathe please?
05/12/2019 10:08:06

David, the switch wiring instructions are useless to you unless you know which terminals have the start and run windings.
I suggest you start by removing the 2 screws holding the paxolin connection plate, move this to see if there is a centrifugal switch fitted. If there is the connections to the switch will be live and 1 end of the start winding, the other end of the start winding can be found by removing 1 of the wires connected from the posts where 2 are connected, a low resistance meter will indicate the other end of the start winding.
You need to identify each cable on the terminal connection board before connecting to the Dewhurst.

If you don't feel confident working with the terminations then best find a local well informed electrician.


Thread: How should I check a milling machine?
03/12/2019 18:17:51

First impressions of machine appearance can tell you something about it's working life, if it has been in an industrial use all it's life there may be some wear issues, you can be sure it was a very well made machine and usually quality counts for a long working life.

It seems you have a pretty good idea of checking the machine over, you may want to check spindle drive and bearings, both horizontal and vertical.
It's important all accessories you are likely to need are included, failing that be prepared to pay excessive prices for them at a later date.


Thread: Breaking bandsaw blades

I seem to remember hearing somewhere that the biggest cause of breaking blades was over-tensioning them.

I've heard the opposite


Neil and Ian, don't worry too much it's only hearsay.


02/12/2019 17:50:59

Try a different make and type of blade, I had the same problem before changing supplier.
Like Jim I leave my blade tensioned.


Thread: Suggestions to pack round DC motor so bracket holds
02/12/2019 17:46:39

You could use 3 or 4 (120 or 90 degrees) packing pieces between the 2 diameters, wood should be OK for small motor,

Thanks for the Dividing head calculator link.


Thread: Those little screws for carbide inserts...
30/11/2019 10:08:17

BCPROF, simple to magnetise the torque driver, put 4 or 5 coils of insulated wire tightly around the tool and flash the ends of the wire across a 12volt battery a few times.

Thread: New Mill - Starter Tooling
29/11/2019 13:19:51

And another reason for not using R8 Collets is that when using small cutters it becomes hard to see what you are doing and any form of clamps have to be kept well away from the spindle.

That's the reason I can't understand why most users here go for ER32 chucks, they clearly don't do small work held in a chuck either on the table or on a dividing head, ER16 is suitable for much of the milling work done by smaller scale model engineers and allows working close to the chuck jaws.

I can only believe it is because they have ER32 collet chucks on a lathe so making greater use of the collets.


Thread: M24 x 2 arbour
27/11/2019 22:41:35

Carl, find an old used MT4 drill, 1" or bigger, cut it down and use that for the arbor, probably a good idea to thread for a drawbar for security in use.


27/11/2019 22:00:28


Get yourself a blank end MT2 arbor and thread it in the lathe.


Thread: VFD off the bay
26/11/2019 22:39:03

I conclude from the answers given some 12 VFD's have been sourced from imports and are working without problem, no negatives from the users.


Thread: Inside chuck jaws

it's only a matter of reversing them and remembering that jaw 1 becomes jaw 3 when putting it them in backwards to grip larger diameters.


I have just picked up a small lever 3 jaw SC chuck to go in a rotary table. It came with no instructions, but no problem - why would you need instructions - until I read the above.

Is this jaw reversal usual and necessary?



It is the case with Emco SL/DB and 3 models the chuck jaws act as inside and outside jaws by swapping jaws 1&3. Also the case with early 5 series chucks that used the chuck key type type key for adjusting the jaws.

I have used the feature on SL and 5 series chucks and found it useful and as accurate as having separate inside and outside jaws, definite advantage is you won't forget where you put the jaws when you want to change over.

Hi Ketan

I did message you via the on-site contact link asking why you don't have a PDF type catalogue to download ?
