Thread: Have You considered getting a 3D printer
11/12/2020 23:28:46

I've thought abouIt it, but having seen the output of professonal machines at work am not convinced by the quality. From listening to others they also seem to be capable of consuming large amounts of time and filament plus a fair bit of money and space.

I'd get more use out of a small CNC mill

Robert G8RPI.

Once you learn the limitations you'll find it easy to work within them and discover that there's a world of stuff you can make which isn't possible to the home machinist. Here's a small sample of stuff I have made:

Cable clips for my computer desk to hold my phone charger leads

Cable clips for my DRO install

Coil bobbin for ignition pickup

Door sliders for metal garden shed

Model intercooler for RC drift car

Coolant drain nozzle for surface grinder table

Square nut with built-in lugs for lathe E-stop button & 1mm pitch thread

New tap handle for the burco boiler at work which you push with your mug instead of pulling the lever with your hand. This was to stop them from removing the hot water boiler from the site canteen as a covid measure back in the spring.

That's just a few examples. It's true, you won't get injection-mould quality but that doesn't make them useless.

P.S. I'd love a small cnc mill too, but you're not getting one of those new in the box ready to go for £200.

and a 3d printer needs a superclean environment

It does? Why?

I had to blow the dust off mine last time I used it :D

11/12/2020 13:35:49

Yes - I got mine last Christmas time. It doesn't see much use but when it does get used it's invaluable. Yesterday I printed and e-stop nut with 22mm x 1.0mm pitch internal thread and a pair of lugs for clipping the stitch onto. I wasn't expecting it to screw on the thread at the first attempt, but after trimming a little chamfer in the lead and cleaning the burrs off with an internal thread file - it did!

I would be interested to know which way the teeth are facing on saws purchased from third part suppliers for this saw.


Mmm.... Do the Bandsaw Blade suppliers know which way round to weld these very stiff blades blades? As Keith said, having to turn the blade inside out might damage it.

If you're worried about it breaking at the weld just grip the blade across the weld with mole grips then flip it inside-out.

Thread: Type identification of a endmill tool holder (Hauser)

Posted by Alexander Smith 1 on 14/09/2020 13:11:58:

I have a Hauser mill which takes the Shaublin P9 collet and looks suspiciously like ypurs( 9mm diameter and 2BA internal thread. If it is, then hen's teeth are common in comparison. I managed to find a couple from a French dealer. If anyone would like to dispose of any, let me know.


Shame that it's not P10 you're looking for Sandy as I have several dozen of those.

Thread: Worn nut ACME 10 TPI Thread by 0.500 in.

You don't have to move anyhting Howard. Just look at the male thread. The handing isn't affected by which part turns.

07/12/2020 18:33:04

Look at the screw. If it was laid flat and the threads were angled like a row of keyboard back-slashes thus \\\\\\\\, it's a right hand thread. If they look like a row of forward-slashes //////// it's a left hand thread.

Thread: Stand in wheel dressing tool
07/12/2020 17:49:04
Posted by Martin Connelly on 07/12/2020 12:56:27:

I needed to grind a piece of HSS today and as I started my grinding wheel started to clog up. I stopped the grinder and found a wide streak of metal firmly embedded on the surface. I think I have ground something that had zinc plating or similar on it without realising. No problem, just get the mounted point diamond dresser and give it a quick skim. Half an hour later still hadn't found the dressing tool (it is a rarely used thing as I use inserts most of the time and have a CBN wheel for HSS touching up purposes).

In the process of searching for it I came across an old segmented diamond edged stone cutting disc that stopped working when the edge wore down. Since the sides still had some diamonds embedded I thought I'd give it a try. Laying it flat on the rest and sliding it across the wheel gave me a beautifully fresh and open face on the wheel with no sign of embedded metal. I will have to cut a segment out to make a more sensible tool now.

They work wonderfully don't they. I've made several of those, often end up giving them away. I have a ready supply of broken/thrown segments from work but the little 4" discs are so cheap if you bought one it would last an a lifetime of dressing in the home shop.

Thread: Is this Gold?

Isn't a Tam O' Shanter a Scotsman's bobble-topped cap.

Can't see the need for sharpening one of those :D

Thread: How does this rotary table bolt down?
06/12/2020 13:28:45

I'd knock up a small toe clamp to fix that down. Saves messing about trying to find just the right length bolt and fiddling with a thin nut in the slot.

Thread: Workshop temperature - cold
29/11/2020 16:18:31

The temperature is pretty stable in my workshop so I have a 2kw infra-red heater on the ceiling that I use for 20 mins to warm it up a bit then my own body heat is usually enough. Whilst I'm waiting for the heater to do it's stuff I might run the twin-motor shop vac around the floor and chip trays which is also a pretty good heater plus it pushes the air about.

Thread: Myford Lathe Identification
29/11/2020 15:25:59
Posted by Angela Smith 10 on 29/11/2020 10:47:04:

Hi, I'm trying to help my Mum sell my Dad's old Myford Lathe but have been struggling to identify it. The number Mum has written down from the Lathe which I presume is the model number is VSB544SR3B175BG. Please can someone help me to identify it? Sorry I've tried to add a picture, but couldn't get it to upload. Any help would be most appreciated, thank you.


As people have said it's a Myford ML7. It looks to be a nicely kept example on the cabinet so should attract the higher end of the price range for it's age and type. It's an older model so it's value does depend on the condition and the number of accessories that come with it. There seems to be some items in the cabinet and depending on what they are could add significantly to it's worth.

If you could take better photos, perhaps close the curtains and use flash or supplement the lighting. Get a good photo of what's inside the cabinet or even perhaps spread it about on the mat and take a photo of it all there. That would help you get a decent appraisal and perhaps a good idea on price. Definitely don't use that photo for a sale advert if you hope to attract decent offers - it just doesn't show enough detail to tempt people.

All the best


Thread: Viceroy 280 VS Inverter

Your e-stop and safety switches can be wired together in series and used to make the RUN enable connection on the VFD.

The suds pump will almost certainly be happy to run on single phase with just a capacitor on the spare leg.

The tacho is probably single phase already, but only investigation will find that out.

You are what you think you are Jon.

Your small-minded colleague sounds like a person with no imagination and precious little charm.

Thread: Help with lathe speed
21/11/2020 06:06:08
Posted by Neil Mccarthy 1 on 21/11/2020 00:13:56:

I am in the middle of restoring my Drummond b lathe and I was wondering if you can have a speed controller on a 240volt single phase ac motor at all as I use to use a cj18a mini lathe and you could control the speed on that one

thank you in advance

Your Drummond's motor's speed is fixed by the 50Hz frequency of mains electricity. Whilst it is possible, it's not practical to alter the way you can with a 3-phase motor.

Your mini-lathe will have a DC motor which is why you can use a speed controller.

Thread: How to Adjust Old Breaker
19/11/2020 23:33:00

I didn't know about them being able to detect a lost phase but they will certainly trip the bar if any one of the heaters cooks the strip too much. It might have inadvertently been 'adjusted' during the re-wire. If it worked before it should work again, I would inspect it to see if any of the components got bent slightly from working in the cramped enclosure.

Thread: Eagle Surface Grinder - weight of parts
19/11/2020 23:02:07

I did say it was a guess - mustn't know my own strength :D

Good to have a figure put against it, as you say it will be handy for future enquiring minds.

Thread: How to Adjust Old Breaker
19/11/2020 21:13:21

I see conductors for a single phase motor. The original was probably 3 phase and therefore drawing far less current..

You might find that the switch doesn't have the adjustment capacity for the extra current draw. To get around this you could remove the neutral line from the contactor and split the live phase between two of them to share the load and if it still tripped you could share between all three. If you have the room to fit one, you could even fit a modern overload and remove the heating coils altogether to turn the overload switch into just a switch.

Thread: Whitworth v UNC
17/11/2020 18:53:34

The two threads have different flank angles. 55 degrees vs 60 degrees. They also have different profiles, Whitworth having rounded crests.

Thread: Chipmaster variator
17/11/2020 06:33:02

It may just need adjusting. If you can adjust the play out and it quietens it down you can fill it with new oil and you should be good for years to come.
