Doesn't the IPA get sticky when it dries?
|Thread: Is CNC cheating|
The problem with attitudes to CNC is that those who don't use it cannot understand the time and effort which goes into learning all the skills one needs to "automatically" make parts, or the work required in CAM to generate tool paths which do exactly what you wish them to do.
I think that a manual machinist who is sniffy about CNC (as once I was) should learn CAD, CAM and CNC Operation to the point where they are competent enough to generate tool paths for complex parts and only then cast aspersions at those who have climbed this particular set of quite steep learning curves.
|Thread: Thread Milling|
Having read this I'm thanking the powers that be that my CAM just works :D
|Thread: Windows 10 forced upgrade|
What CAD/CAM do you use?
I've not found a good multi-axis CAM package for Linux yet.
|Thread: FLORID SCRIPT|
That would do fine if you're not trying to reproduce the original, if you were then there are so many fairly obvious differences that it would be more work to modify the font that's "almost right" than to create new artwork from a good scan of the original.
|Thread: Coventry die head question|
Definitely two teeth short of a Die Set
|Thread: Windows 10...more worries so listen...|
They know if they get people onto the new software distribution model they've got customers (and revenue stream) for life.
Additionally some things which were in with Windows no longer are, Media Centre, DVD Player, probably other stuff, you either have to find something to do the job which W10 will run or visit the Windows app store and buy (Rent?) something to regain the functionality you had prior to "Upgrading"
|Thread: Thinking aloud... reduce diameter of glass filter|
|Thread: One Man and His Lathe Articles Sought|
I have a long bed Super 7 with a 30.5mm through capacity and native ER40 spindle nose
|Thread: Dead Sino DRO|
Allendale Electronics /Machine DRO can supply replacement PSUs for the SINO DRO units
Take the cover off the PSU and check the electrolytic capacators, if the top is split or even just bulged it's probably toast.
I just repaired a dead SINO DRO with £0.85 worth of replacement capacators from Maplin
|Thread: Insulated Garage Doors|
I filled in the back of my up & over door with 2" insulation foam bonded in place with building foam, all gaps, voids & corners then filled with building foam and trimmed flush. Brush draught strip sides & bottom with rubber draught strip at the top.
The garage now requires just a small fan heater on thermostatic setting for comfortable working on very cold days, the door is much stiffer, noise reduction was an unexpected bonus, you used to be able to hear my radio 25 yards away at the top of the drive, now you can't hear it with your ear against the garage door.
|Thread: Mach 3 DRO question|
It doesn't, Mach3 depends upon the stepper system being correctly set up and not losing steps, there is no feedback.
You can use inputs and scales to display positional data in Mach3 DROs (not the active ones under progrm control) but the software will not reference the data in real time or use it for positional correction
|Thread: EMCO FB2 vertical Milling Machine|
Emco FB-2 -
Remove the 4 top cover fasteners, remove the bolts on the inside which retain the motor and then drill the right holes to fit a flange mount alternative or even drill & tap a non flange mount front cover and bolt that on.
The FB-2 is a 6 speed head, the earlier 4 speed milling heads (MM1?) appear to have the motor front/gearbox top as an integrated casting -
I'm only referring to the FB-2.
The FB-2 motor is bolted to the top cover of the gearbox, it's a small diameter motor frame for it's power output but that's all that's wierd about it, it's spindle has a standard nose for it's shaft size, I just machined my new motor's spindle nose to match in size and screwed the parts on.
If you were to go with slightly less power than I did then frame size wouldn't be an issue and the motor could easily be replaced. After all, it's just a motor and "Where There's An Engineer There's A Way", conversely I suppose "Where There's No Engineer There's No Way"
I've fitted a 4 pole compact frame 0.55kW motor and 240V Omron inverter to my FB-2 head,
The standard motor shaft was a size smaller so I stripped the new motor and re-machined the shaft nose in the lathe.
The flywheel, primary drive gear and gearbox oil lift screw all attach to the shaft via the internal thread in the motor shaft nose.
The plastic gearbox oil lift screw shaft is easily broken if the motor isn't carefully lifted out vertically but it's also easily repaired with a section of speedo cable inner and epoxy if you do break it and once you repair it this way it's no longer sensitive to handling or alignment.
Measure your proposed motor carefully, even the compact frame motor I used required a spacer ring to move the mill head 8mm further out from the column, I could have removed a couple of fins and slotted the fan cover but I fancied the additional 8mm throat.

|Thread: electric motor for the quorn.|
How cheap is cheaper? If you gave price, rough dimensions, power output and speed it would be a big help.
I'm using a (new) 0.18 Kw 3 phase motor and (ebay) VFD (for my engraving cutter grinder) that cost me £110 in total, how cheap do you need the solution to be?
|Thread: Gauge Blocks|
It ensures the surfaces are free of dirt, you could use water but it would promote corrosion, you could use a degreaser but that would remove any surface corrosion protection.
The assumption that the presence of oil will affect dimensions is bunk, if the metal has close enough contact to "wring" it will do so, if something is preventing intimate contact it will not "wring"
I spent an entire Summer Holiday calibrating micrometers to ISO 9002 for IMI Leeds
|Thread: How close does a thread pitch need to be?|
The reverse should be possible.
