Thread: Watchmakers / Jewellers Drill
04/05/2021 18:14:33

Thanks.

I've just finished stripping it down and removing the old paint. Judging by the way it's been made, which is rather crude and almost like it was put together in a hurry. I am starting to believe it might have been a kit of parts finished by an enthusiastic amateur or as an apprentice piece?

Hi guys.

I picked up this little watchmakers drill at a bootsale at the weekend. It's a abit crudely made but it's a charming little thing. I intend to strip it and refurb it. But before I do I would like to know if anyone knows anything about it? I've sesrched the web but cannot find another the same, nor any brand that looks similar?

Thread: Quick change tool post and parting tool for a lathe

I use the "T51" size toolpost on my Boxford. If you buy the set it comes with a parting tool and holder.

Thread: Machining titanium.
25/04/2021 09:10:13

I'm not an expert with titanium by any means but have done some work with it.

The thing to remember is that it work hardens very quickly if you don't keep the cutting temps down. Incidentally it heats up very fast and seems to hold heat. Therefore sharp tooling, slow speeds and coolant are a must. Expect to ruin plenty of tooling if it is too hot!

IMO turning doesn't present much of a problem, drilling and tapping on the other hand can be difficult. It is sometimes easier to bore holes in titanium than drill in my experience. With tapping you might find the tap has a tendency to get stuck often, again if you can "single point" screw cut that can be an advantage.

Thread: New EBay payment regime
23/04/2021 09:38:08

Had a bit of a nightmare with this new payment thing. But that's a story for another day.

Anyway..

Firstly you need to choose whether you want to be paid (into you bank account) daily or weekly. The payments are then "processed" which takes about a day, before being sent to your account. This usually takes another day but reading their terms it can take upto 4 days!

For me I am usually paid very early morning and then the funds appear in my account about 1pm

Sherlines are nice machines and they seem to punch well above their weight considering their small size.

It's frankly unbelievable that their presence in the UK and Europe is almost non existent! The market over here is very strong.

Quite well-known in the UK with a good reputation, and there's a dealer too. Unfortunately the machines are Price on Application, which often signals high cost and long delays over here.

As a general rule importing anything from the USA is expensive and what's delightfully affordable in New York causes British purchasers to blow a gasket when they see the price over here. Quite a good way of buying american gear is to take a holiday in the US and bring it back as hand-luggage.

Another problem might be more competition. Europeans have reasonable access to second-hand watchmaking lathes and - for serious players - Cowells can be bought new. Also Taig/Peatol and Chinese micro-lathes.

Perhaps the biggest problem is UK lathe buyers have bigger machines for general work and don't have room for a little one as well. Many of us have cramped workshops because land is so expensive.

Whatever the reason, it's not because Sherline kit is considered unreliable or inaccurate. Just relatively pricey, small, and a little awkward to buy. I think of buying a Sherline once or twice a year because my other machines make intricate work harder than it should be. Don't do enough delicate turning to justify it though. Maybe one day...

Though I am aware of Millhill, Well known is not words I would use to describe them.

It's basically one obscure website with no online shop to pretty much serve the whole of Europe? A job that IMO they don't do particularly well. I emailed them about 6 months ago and I am still waiting for a reply. 🙄 I mean they don't even advertise on forums or in the magazines. I imagine most people have no idea who Millhill are or even that they exist.

It may seem a little brutal of me but IMO Sherline should dump Millhill and partner up with some of the bigger boys, Chronos, Warco, Arceuro, Axminster etc to really get their products out there. I am convinced Sherline have the products that fill a gap in the market over here. I collet micro lathes and the choices available new are basically a cheap Chinese c0 an overpriced Proxxon or a very expensive Cowells. Everything else secondhand (Emco) commands a premium because of demand and the watchmakers stuff isn't really suitable for model engineering.

Second to that some of their range of chucks would fly off the shelves over here. A very nice quality American made precision chuck for example costs about $100 which is a bit of a bargain when compared with similar offerings over here which are crudely made usually in China yet cost almost as much?

Sandwich the metal sheet between 2 pieces of wood and then you can just cut through the whole lot with a scroll saw. 😉

Thread: Loctite or Draper? Much difference?

While we are on the subject, it's worth noting there is a LOT of fake loctite around at the minute. I'd be wary of buying from ebay or amazon!

With that in mind what other brands do people prefer?

I agree. There do seem to be too many variations on eBay and Amazon. One reason I thought the Draper might be safer.

Oddly enough, the last threadlock I bought was "Loxeal" brand. Made in Italy. Might be worth a look.

While it's in bits spray some WD40 down the hole and let it sit for a while. Re assemble and then just wind the quill all the way back. The chuck taper should be self ejecting.

Thread: Electric motors
06/04/2021 10:42:24

Your choice of motors is almost endless. You probably just want something reasonably small say 100 to 300w AC

Brand wise I don't really think it matters. Parvalux make good small motors. But I think even a Chinese machine mart special would be fine.

Thread: Milling machines - western-made s/h recommendations up to £2k
06/04/2021 10:33:04

William

I was in the same position as you not too long ago. Similar budget looking for a mill of similar size and like you I prefer British made stuff. I try to avoid Chinese machines if possible because in general I've had bad experience with them.

However in the end I bought a Myford VMC which I believe is Taiwanese made. The overall quality of the machine isn't bad at all. If the Chinese versions are as good I wouldn't hesitate to buy one. Infact I actually plan to buy another in the future.

So that leads us on to 2 more options. The warco VMC and the Chester 626. if you could get the chance to inspect either of these machines you might satisfy your concerns over build quality.

Considering they are just over £2k new with warranty, delivery and you get to choose spindle, phase and metric or imperial versions they begin to look pretty favourable.

Worth investigating.

Thread: Buying advice sought re Milling Machines: e.g. Proxxon: FF230 vs. BFW40/E vs. MF70
31/03/2021 19:58:33

I've had a few small mills and used quite a few more. Imo the sieg sx1lp would make most sense for your applications. I would just put up with the weight.

You see the problem with most of the very small machines is the round column. Trust me it soon gets tiresome loosing position when making adjustments.

The Sherline is not a bad second choice, its a nice machine (regretted selling mine) and it could be modified quite easily to better suit your needs. The motor for example would be fairly easy to swap and you could buy a "sensitive drilling attachment" to make drilling easier.

The only other options are an Emco 5 mill or Cowells mill. Unfortunately both of these are quite rare/uncommon so finding one might be a challenge.

Thread: Component Suppliers - Recommendations?

I use these frequently:

CPC

RS

Switchelectronics.co.uk

Also you might be surprised to find screwfix sell momentary push button switches in several NO / NC configurations.

Thread: Gluing Aluminium
31/03/2021 08:47:14

I've used arldite 2 part epoxy to glue aluminium endcaps into aluminium tubes many times. The joint is very strong. In fact the chances of pulling them apart is almost none existent.

Thread: 12V Motor for a Top Slide Drilling Attachment
18/03/2021 16:09:48

Thinking about this why not construct a belt and pulley arrangement?

You could use a slightly higher speed motor and use a 3 pulley arrangement to give you a range of speeds and torques. Maybe something like 1:1 ratio for small drills and maybe 4:1 ratio for bigger drills and cutters? It wouldn't be difficult to make.

Thread: That little elf under the workbench again
18/03/2021 16:00:55

I remember once dropping a small part I had just finished turning on the lathe, I couldn't find it anywhere even after about an hour of searching where I saw it land. I was kinda annoyed considering the part took about 2 hours to make. I did eventually find the part about 6 months later. It had bounced up inside a cabinet drawer and landed perfectly balanced on top of the door hinge! The odds of that happening again must be a billion to one!

Thread: 12V Motor for a Top Slide Drilling Attachment
18/03/2021 10:10:52

A DC scooter motor would be ok, preferably 24v

A "spindle motor" (the type used in diy cnc routers) might also be ok. Though they tend to be high speed rather than high torque.
