Thread: Rotary encoder for spindle speed
08/03/2012 01:51:19

i've just (about) finished a speed display on my mill. I used a reflective style photo-interrupter
(ex some unknown piece of equipment). As a reflective device. I simply printed out a disk of 60
black-and-white segments, glued it to the top of the spindle pulley, and mounted the interrupter
over it.

This feeds a $20 digital frequency meter. 100 rpm = 6000 pulses per 60 seconds = 100 Hz on
the display.

(plan A was to produce a large disk with 60 holes overhanging the pulley, using a slot-type
interrupter. This way i dont have a sharp disk spinning around)

It works, but the display is a little unstable. I think i still need to adjust the position of the sensor.

Thread: Forgework of small parts .
06/02/2012 02:37:56
Hi Michael
 
I agree, one of my (former) hobbies was blacksmithing. It seems to me that many people spend a long time turning a big chunk of metal into a small chunk, when my immediate thought is to forge it. Cheaper, quicker, it would in many cases need finish machining to get the dimensions spot on, but not always.

Thread: Yet Another Digital Subscription gone AWOL
05/02/2012 06:25:43
i had this exact problem last year. because the 'last' magazine of your subscription has been delivered, you are turned off. Never mind you didnt have time to read it.
 
If you continue your subscription there is no problem. If you dont, then i'd think you have a case for non-delivery.
 
(the only official way of getting a copy to keep is of course print edition. They aren't really selling 'digital copies' - just online access)
 
 
edit: just checked my access - its gone too. No reminder, but it looks like i renewed last January.  nothing like great customer service to keep your customers. Whats EIM like these days?

Thread: Milling - what do i need
02/02/2012 02:15:06
thanks everybody for all the comments...although of course i did actually buy the mill quite some time ago now, the thread suddenly gained new life.
 
I have learnt a couple of things so far...
1. R8 tooling isn't as common is Oz as i expected..
2. A vise is definitely useful, i agree there are some cases where other approaches are better but the vise is quick where it can be used.
3. i will have to invest in some more tooling, ball nose, pointed end mills and a couple of slot mill.
 
i have managed a cylindrical square, my 1915 drummond lathe is more accurate than i expected!. Now to finish an old angle plate, then some parallels, boring head, and rotary table of some description.

Thread: drill stand
22/11/2011 01:11:39
I recently discovered a design 'feature' of a cheap set of taps...
They have no taper! a 60deg point, like a lather centre, then straight - like a bolt with grooves down the side!
really hard to start - in the end, i stuck it in the drill press, briefly hit the power switch to get it spinning then rammed it into the work. Sheer brute force got it to bite, but its obvious i have another 'investment' on the horizon. (actually, 2 sets, both metric, have the same 'feature' - maybe i could grind a taper onto 1 set?)

Thread: Milling - what do i need
16/09/2011 12:00:16
thanks all.
 
the machine i'm looking at is 3 phase, R8, with drill chuck, face mill arbour (i assume not the face mill), and a reasonable swivel vise, clamp kit, at a fair discount. Not sure if it is metric or imperial, i guess metric.
 
I'll get a 3phase VFD converter, and an R8 chuck for my ER25 collets.
 
 
I've been doing a lot of research, and am fairly comfortable that the style of mill (turret, knee) will meet my needs. Based on replies, i think i will be set to start work at least.

Thread: Hacksaw blade tension
12/09/2011 05:24:42
i usually set mine pretty much as tight as i can, by hand, and i try to release the tension when done.
 
haven't broken many...

Thread: Milling - what do i need
12/09/2011 05:22:56
Hi All
 
I am contemplating a mill purchase. Possibly a VMC type (6x26 in american parlance i think?) - see Standaco DM15. (any other Oz recommendations?)
 
Apart from the mill itself, what else should i consider as a minimum to be generally useful? A vise? clamp kit? face cutter? Rotary table?
 
I dont want to blow my budget and find i can't actually use it.. This is definitely at the upper end of my price range, but i have taken on board advice to get the most solid i can manage.
 
Consider the requirement to be for general hobbiest, including tool manufacture and components for small (non-railway) type engines.
 
I am also considering a 3-phase version, with a VFD like ebay 280735292600
any comments on that?
 
thanks!
Thread: Benches
09/09/2011 06:33:13
i used 8 x 3 redgum sleepers, with a leg frame of 4 x3 hardwood. Really hard wood, with a handsaw..
 
i was too impatient, and it warped after i first leveled it (and the glue joints split), i then drilled through horizontally and used all-thread to bolt it up. I can hammer on the middle, with no jumping. (and its almost impossible to move.
 
I should relevel the top and put a smooth top - laminate, masonite, etc.

Thread: Rust and how to remove it.
01/09/2011 06:55:30
Phil P: apologies, i should have read the entire thread before posting...

I've just been trying a product called 'Evapo-Rust' - it is apparently a chelation process, non acidic, entirely safe. It claims to not remove any metal, only what is already oxidised.
 
It appears to be very effective, cleaning up a small setsquare, some pieces of machine knitting accessory 'linker', and also some meccano. It leaves a slightly dull surface apparently suitable for painting.
 
Its a US product, available there and Australia at least, not sure where else.
 
hope this helps.

Thread: Motor wont start
01/06/2011 03:58:14
Its also possible that the motor is 'poling' (sp?), that is, the bearings have worn and the rotor is touching the stator. From (1) experience, the motor will run if given a push, but presumbly the combination of the increased friction and the disruption to the magnetic circuit/flux pattern means it cant self-start.

Thread: BBC TV show that might well appeal to ME readers
04/03/2011 01:51:05
For us colonials, would it be possible to share the name of this new program? A faint hope that it will ever appear this far south, but it is possible.

Thread: Digital Subscription renewal
03/03/2011 00:17:56
well, i still dont know what problem my referrer had, but i do have access to the archive again...

I have just attempted to resubscribe to MEW digital. My last expired last month, but i was very reluctant to renew because my access was actually removed about the 2 Jan, and subscriptions.co.uk refused to answer any further emails after explaining that 'my subscription expired with the Feb edition' - even though that hadn't been published at the time.
 
Anyway, since it appears that I just have to put up with their poor attitude to customer service if I want the excellent magazine, i decided to resubscribe. All appeared to go well, until this message:

Signup Complete

Sorry, there was a problem with your Referrer. Please contact Customer Services.
 
The link to customer services is actually to the 'about' page, on which i cant find a reference to customer services. So, I dont know whether all is well, or i somehow need to contact the mythical customer services to fix something.
 
(and then i need to hope that 12 months access means 12 months - in fact there will be no hope about it, i will pursue the matter vigorously if its even a day short of when i get granted access)
Thread: Cast Iron welding Sticks
21/01/2011 04:41:00
that sounds like the dillon/henrob torch. It's claimed to havea very hot, very fine flame that allows the weld to be made with very localised heating, hence no need to preheat etc. Also used to repair dies for injection moulding.

Thread: archive
17/01/2011 02:28:25
my MEW archive has also disappeared, appeared to expire about 3 weeks before it should have according to original subscription emails.  No invite to renew, either.
no response (other than the initial 'we'll look into it', a week ago) from subscriptions.co.uk,
 
regards
