Have you tried Camping Gaz bottles ?

|Thread: Tool steel - Beginners guide ?|
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.
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|
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 ?
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?|
David, the switch wiring instructions are useless to you unless you know which terminals have the start and run windings.
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?|
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.
|Thread: Breaking bandsaw blades|
Neil and Ian, don't worry too much it's only hearsay.
Try a different make and type of blade, I had the same problem before changing supplier.
|Thread: Suggestions to pack round DC motor so bracket holds|
You could use 3 or 4 (120 or 90 degrees) packing pieces between the 2 diameters, wood should be OK for small motor,
|Thread: Any users of the 'ModelEngineersUtilities here?|
From another topic thread, takes you to ME Utilities

|Thread: Does anyone know about this dividing head.|
Thanks for the Dividing head calculator link.
|Thread: Those little screws for carbide inserts...|
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|
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|
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.
Get yourself a blank end MT2 arbor and thread it in the lathe.
|Thread: VFD off the bay|
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 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.
|Thread: ARC Catalogue No.11|
I did message you via the on-site contact link asking why you don't have a PDF type catalogue to download ?
