Thread: Spindle thread wont engage ml10...
11/04/2021 16:01:13

If it is the register that is tight be very careful about lubrication and not putting the hot chuck on the cold spindle or you will have a shrink fit. Rather than taking 'taking 2 thou off' it should be a case of very gentle application of fine sandpaper.

Thread: MS 'Edge' - Points and Pitfalls?
11/04/2021 14:08:48

I get annoyed by some of the other stuff pushed at me. Owing to the way the Company IT controls our computers I get the browser options I reset to default advertising every few days and a few similar things. On a similar vein every time I open Google search it wants to display the top ten trending searches. Like I care what other people are up to as I opened you for aspecific serch of my own.
But just now after reading this thread I had a look at the top ten the great unwashed are searching. Predictably lottery results are high, and C19 related items feature wrt holidays Along with some second rate politicians and celebrity names I've never heard of. But top of the list was a religious festival I didn't know was I assume imminent.
The list will have changed by the time you look but let me know if motor brushes searches have hit the big time frown Well maybe I don't need to enter the search now if Google have read my forum entry.

More and more sites are not working with IE, like Groups.io and HSM and I think one of the Federations of Model Engineers. On the other hand one of the services I use at work only functions with IE. My work computer under IT dept control has been gradually enabling parts of Edge, like the favourites bar only activated last week - yes it is designed to allow more control by corporate IT aswell. Added to that we have just gone to 365 and Teams is replacing Webex and Skype and a couple of other business applications in phases over the next year, just in time to complete re-learning as I retire.

Thread: "TINKER" tool & cutter grinder
10/04/2021 00:04:13

I have the castings and plans somewhere bought at our club auction when nobody else was dumb enough to show interest. Frankly I'd be ashamed to charge for fully printed copies of the poorly presented plans let alone a zero expense electronic copy. When I got them I did a bit of internet searching and found somewhere a picture that showed the advisable modification of making the horizontal micrometer adjustment work like the Quorn.

If you need drawings to make such a simple device without being able to understand enough about it not to need drawings then you could be in trouble as there are some design flaws from what I remember that prevent accuracy being maintained.

As per your request I won't mention the name of almost any other jig that would be a better alternative.

Thread: Elliot omnimill horizontal lead screw
06/04/2021 18:43:58

Have you asked on the Elliott group? Someone who has CNC'd their machine might have a spare unless you are also aiming to go that route. If you can get a spare you can remachine it to have an even 'wear' all aong and then make an anti-backlash nut.

Thread: Boxford Model C leadscrew half-nuts
05/04/2021 18:15:29

Certainly an interesting fix.
I notice the rotation of the bolt also applies some longitudinal movement so there is potential (with good nuts) for using this to take up backlash for anyone using the lathe and vertical slide for milling.

Re the screwdriver slot. Perhaps one at the front, ie threaded end, or a hex dilled in would be avantageous.

Thread: Solar panels for water heating
05/04/2021 12:42:13

If you want alternative energy advice search for the 'Navitron' forum. It is the equivalent for that topic of this site for ME and is likewise populated by more sensible contributors than the 'eco' forums. Last time I looked at it solar water heating by vacuum tube collectores was still not ecenomical payback/life of equipment unless you were already in need of a new plumbing makeover or new build house. Solar elctric > water is less efficient but the electricity is multiuse so works out a more ecenomically sensible choice.

Thread: Rocketronics Electronic Lead Screw
05/04/2021 09:17:32

You haven't said which lathe you have but below £3k adding an extra £1k to your budget will get you into the realms of a very good lathe for amateur use. This device, being specialised electronics will become virtually worthless the moment it is bought, and uness from a major supplier has no garuantee of long term support.
The link you have given seems to be a £500 CNC type controller.??? I haven't tried translating it.

Thread: Boxford Model C leadscrew half-nuts

just a general comment about the video. When cutting external threads, the school of thought is to set the top slide at 1/2 the thread angle, and here we have an ACME thread plunged in normal to the thread axis. Is that special to ACME threads ?

Bob

try drawing it on paper and you will see that teh angled approach doesn't provide the same advantage on this sort of thread.

NDIY - that's a really interesting suggestion.

Thread: Building a small bench
03/04/2021 13:29:07

I like the way you have incorprated the Bisley and teh space for the stool.
As the top is virtually impossible to remove perhaps you can lift up a piece of paving slab into the space under the lathe and hold it with battens at the sides that don't get in the way of your knees. Another good option would be to put a sheet of ply across the underside of this space and fill the cavity with dry sand. In fact you could experiment with small bags of dry sand positioned around the lathe.

Thread: Boxford Model C leadscrew half-nuts
03/04/2021 11:37:16

The tricky part is the way they are on an arm as a casting and there is not much meat in the bit surrounding the threaded part. Not sure how easy it will be to find a nut in the UK. Then make sure your silver soldering is up to scratch to attach the embryo nut as the residual wall once threaded won't be able to add much support leaving only the back wall of the thead to grip.

Given the number of SBs and Boxfords out there wearing out I wonder if anyone has tried a temporary 3D print nut and arm to enable the lathe to do it's own threading of the replacement.

Thread: Wire Gauge Drills
02/04/2021 22:59:11

One of the techniques in this stuation is to find the wire you want to use and make a D-bit out of it to ream the hole you drill just below size.

Thread: Chinese junk
31/03/2021 20:30:10

It's not just the Chinese themselves. We bought from the Korean's but after a year the Accountants said "ok but next year we want it 10% cheaper", or perhaps it was the new design but at the old price. So the Korean's had to go to a factory in China. Then after a while the Accountants played the game again so the production went to the Philippines.

Thread: Steel tube for sand muller
31/03/2021 11:53:23

As Les says rather than slavishly following a design see what is to hand. Eg saucepan with plate welded on, multiple discs eg weight lifting discs that turn out to be concrete not nice iron. I'm no expert but think a muller rather than a mixer is more for oil bonded sand that is caked in use.

Keep updated on what you make - I hope to need one too one day (due to need to use not due to debility).

Thread: Hi from Cambridgeshire
28/03/2021 10:07:51

Hello Mark. there are several members on here that are in and around Cambridgeshire. Are you a member of the Cambridge club? I vistited them a couple of years ago and was very impressed with their operation.

Thread: Replacement Chuck for Hobbymat MD65
28/03/2021 10:04:46

I have a 100mm low profile independant 4 jaw for mine but it is a little large. I would not fit a larger 3-jaw than the original, especially if you need to make a match plate becuae you can't find one withthe oringnal stud spacing. If you need to hold something bigger than the existing chuck will take it is a good indication that you need a bigger lathe.

Thread: Class 22 Diesel (next project)
26/03/2021 15:42:06

Enjoy seeing your updates - keep it coming with whatever is next.

On the electrics may I suggest a headphone socket, 1/4 in type, put in series with some part of the control circuit and attached to the driving trolley so in the event of a breakaway it is pulled out. Also don't make the lead for the control long enough for children to dangle it near the wheels when driving.

Thread: Are we being listened to on the phone

So you need to test it by chatting about lathes and machining, or cooking beetroot or whatever. Let us know the best beetroot recipes tomorrow.

Thread: LG TV ... updated webOS
25/03/2021 23:04:50

What do iplayer and Netflix have to say about these people blocking access and or profiting from the adverts linked.

BTW Philips did a TV download last week that is causing problems I think with HDMI connections but they have put their hands up to it and sorting it out. So far we've only had reports from Scotland so possibly they roll it out regionally and will have halted for the rest of the country.
