If Slic3r has an equivalent to Cura's "Z Hop When Retracted" option it might be worth trying as it may stop the print nozzle banging across the infill whilst travelling.

A search for Bluetooth ear defenders throws up a lot of suggestions. I wonder if they also work the other way, protecting commuters from the wearer's choice of music?

Perhaps the part to be pulled has three (or six) round holes? The pegs could be inserted from outside and wired to hold them in place.

Why change? The principle applied by the Meridian Conference in choosing Greenwich as the prime meridian because it was most widely used on charts could also be said to apply to CE and BCE dates. It is bad enough having to allow for OS (Julian) dates of historic events without adding a third and equally arbitary system.

Looking for stepper motors I found this on Amazon. Funnily enough, it is a feature I was rather hoping to avoid.

I've been using Mymemory for years, quick service and never had any problems (unlike 32GB SD cards dredged up from a certain South American river, rejected because they were 2GB cards with altered firmware).

I like the all metal Kingston drives, £13.99 for 64 GB.

As far a super cheap terabyte memory cards are concerned, this video just about nails it https://youtu.be/J-D6tYBX8vE

The water gauge shown in David's photo appears similar to that drawn by Martin Evans. Perhaps, like LBSC before him, he considered its simplicity outweighed its disadvantages. As drawn, Simplex doesn't have any draincocks either, removing any need for tapered cocks on "A simple powerful engine that is suitable for the beginner who requires ease of construction".

Or try online. Click on the link, click on the picture, print and cut out...

Ideally take your time over this, perhaps paste it to some card or use it as a template to cut one out of aluminium sheet. Stamp on the numbers and finally polish it. Almost certainly the one you bought will be found lurking just behind the metal polish

I don't see a problem with the use of the screws to align the vice, it evidently works well on conventional dual screw vices. What bothers me is the near impossibility of getting equal clamping pressure at both ends of a large workpiece. Almost certainly one screw will tighten more than the other. Perhaps the simplest answer (other than ditching the chain and fitting dual handwheels like most other dual screw vices) is to give the vice a floating face, pivoted at the centre. This could be a separate timber component, dropped in when needed.

Those suggesting violent actions forget that they would also affect a good neighbour who tries to take the parcel in until the recipient returns home. In our street this would be much more likely than theft.

Hi Andy

This is on my "to do" list should I be able to use my SL (I must first print a set of guards so I don't fall onto the pulleys or chuck, which I suspect would hurt) although I would probably go for ER11 as I already have the collets.

**LINK**

Each of the stages in making an ER16 collet chuck on the Unimat SL is illustrated, and each photo has a text description. The screwcutting is done by an ingenious method that takes advantage of the headstock quill movement, which removes the need for the rare and expensive Unimat thread chaser and masters.

Coincidentally, I got curious about my e-mail account this morning as my host permits "unlimited" forwarders within a domain. With 26 letters and 0-10 there are 36 possible characters, and you are allowed 64 characters before the @. This suggests (if my vague memories of 1970s stats classes are correct) that there could be 36^64 + 36^63 + 36^62+.....+36 permissible e-mail addresses on a single domain!

Whilst I suspect the sun would be long dead before I could set them all up, effectively it means my "catch all" forwarder can pass on e-mails sent to more addresses than there are atoms in the universe... I don't think I have ever typed the word "freaky" before, but I think this might deserve it.

Has anybody ever had the plastic gears wear out rather than just substitute for a shear pin?

Surge protectors for ADSL seem readily available (Kenable list one at £2.44 **LINK**  ) which together with a surge protected extension lead might help protect your modem. Protection for telephones seems a bit less easy to find, but Masterplug make a BT plug adaptor (currently £3.49 on eBay **LINK** )

Brian

(No connection to either vendor except as a satisfied Kenable customer)

The 2.5 inch association say they can provide copies of the build series. I don't know if joining might be cheaper than buying the magazines, and of course if you aren't a member of a local club they might be able to help with boiler testing and advice. **LINK**

I found a fluorescent out in our clubroom the other day. Decided to try changing the starter and found it had been so hot the casing melted (to my surprise the tube lit as soon as the starter was removed - I didn't have a torch so had left the lights on). To be honest, I had thought it a one-off but this thread is worrying.

You could point her at SketchUp which does the job without much of the functionality and attendant complexity of 3D CAD packages. As well as there being plenty of tutorial exercises online, the are converters both ways between .skp and .stl files, so it is easy to modify (remix) downloaded models.

Personally, even after 20 years of 2D CAD I cannot get to grips with 3D CAD, but find SketchUp intuitive as it is closer to modelling software like 3dsMax and Blender.

Assuming it is the 9.5mm wide 1.5x 70 belt, Amadeal, who also sell the Real Bull machines list them. Incidentally, the picture under "Bed for the mini lathe" on the Amadeal website shows the two slots by which the motor is mounted.

Brian

It sounds like your belt is way too slack (especially if you can fit it without adjusting the motor position). My son's machine had the same issue, with the belt slipping on deep cuts or parting off.

Unless anything dramatic has changed between Warco's mini lathe and super mini lathe, there won't be any adjustment mechanism visible when the motor cover is removed, as the motor slides up and down, rather than pivots. Remove the four screws holding the control box on the front of the lathe and move it to one side so you can see the motor bolts in their vertical slots. It is a couple of years since I did it but I am pretty sure I removed the motor cover at the rear as well in order to hold the motor when adjusting.

It is important to ensure that when you tension the belt the motor remains level or the belt will not run true on the pulleys. In the absence of any tensioning instructions I tightened it until I could just turn it 90 degrees, at which point there was no more resistance than turning the motor without the belt. Since then there has been no sign of bearing wear and no slipping, so that is probably about right.

Brian

Personally, I would contact the supplier first if the machine is still in warranty, as they could consider that attempting to fix it voids the warranty.
