Thread: Problem with my downstairs ;)

They look like regular slotted round nuts to me.

Thread: Lathes as bling!

Perhaps the owners are getting on with their real business?

I have tools that haven't been used in years, and their cosmetic appearance shows that. But it doesn't affect their utility.

Indubitably they are doing something else but the damage on that lathe is not cosmetic.

As it sits, it's not a working machine. That machine's been brought in from being left outside and disregarded.

Rail preservation guys should know better. My dad ran a rail preservation workshop and the sight of that would have made him very sad knowing how difficult it was to get quality machines especially smaller ones like the HLV.

If it's being used, who cares what it looks like. It's a tool, not jewellery

I agree with the sentiment but that machine isn't in use. All of the handwheels are red with rust.

Meant to add - Lathejack's work is damn nice. Anyone would be proud to pull off repairs that good.

Difficult to understand why spare parts are so hard to get and so expensive for so many of these machines, and not just Colchesters .Would be enough to put anyone off trying to save them

Who would keep a gear change selector dial knocking around in case someone needs it? Space costs money.

A couple of years ago I called up Boxford for a part and the guy said 'you better be quick, next week we're clearing out everything that we haven't sold one of in the last 5 years.'

You could have a nice Hardinge copy from Grizzly complete with ELS for £29K

It is rather nice. Perhaps Boxford could copy it (I doubt it).

A bit of reverse bling.

Shame to see such a fine lathe in such a terrible condition. It could be saved but not without a huge amount of work. I'm nearly completed with a full rebuild of the exact same model. Bed grind, apron rebuild, new motor, new electrics, new spindle bearings all the sliding parts scraped.

Thread: Cutting teeth on a spur gear
17/01/2020 22:09:47

Eric the first thing I'd do is measure the OD and tooth count of the larger mating gear so you can get a proper idea of the tooth pitch. This thread claims that Hornby used 40DP.

This one

is from a UK source, so shouldn't attract import fees.

I bought a 3 axis kit (£224 delivered from UK source) last year - supplied in two cartons (one with individually boxed scales + mounting hardware, the other the readout & mounting arm) whaich came in under a week. Strangely the scales were delivered by Hermes & the readout by ParcelForce on the same day.

Had the whole lot connected up on the bench to check it all functioned (which it did), but still "ongoing" with the fitting to the mill, so no actual usage experience.

That seller is in China and he has dreadful feedback.

Thread: Biax Power Scraper
14/01/2020 17:53:43

I have a 7EL too. The chrome ring was stuck when I got it and I had to warm it up to get the motor off the gearbox to get at the fan. Even though it's old I use it a lot.

Which models did you get John?

Thread: Cut a transverse tapered hole (Unimat milling column)
11/01/2020 15:56:42

Actually Michael, that's a good idea. Make the spigot so that it has a fine thread to screw into the post.

11/01/2020 13:31:32

I agree Ian that's why I said leave it 1/16" short to begin with. Easy to fine-tune as a last op.

Thread: Biax Power Scraper
11/01/2020 12:51:54

The early Biax motors were made by Scintilla AG (who made the first 'Lesto' Jigsaw), a Swiss company, later bought by Bosch. This is why you can't get motors for them. The green Biax motors are Metabo and share parts with Metabo tools (jigsaws) than commonly appear on the used market. They all say 'made in Switzerland'.

Thread: Cut a transverse tapered hole (Unimat milling column)
11/01/2020 12:41:05

I would do what Clive suggests. Get the cone cutter and make a bolt to suit the taper it cuts.

It's unclear whether the cone bolt pulls the post down tight against the shoulder or if the 20mm diameter is a very close fit and the head of the cone bolt a close fit in it's hole too. I would suspect that the cone bolt bears only on the bottom of the taper to pull the post down hard. That would seem to be the most rigid setup.

First turn the 20mm diameter on the post but leave the shoulder 1/16" short or so for adjustment. Cross-drill the post using a crotch centre then use the cone cutter to make the taper. Once the taper is cut, turn a matching cone bolt and use blue to match the taper.

Thread: To use chuck or collets
11/01/2020 08:40:53

I'm a big fan of using collets but an ER adapter on a 3mt taper is probably going to be too limber for any kind of decent milling cut. If you're doing very light work then you'll get away with it. If for instance you use it to hold a piece horizontally to mill a key slot you'll probably need to put a jack under it to stop it deflecting.

Used within their limitations, they are great.

You'd have half a chance with a modified recip saw but those multi-tools aren't up to the down-pressure required for scraping.

Thread: Balzer relieving attachment working model
10/01/2020 22:25:11

Gary, thanks for that, I was a little concerned about the conversion file not having the ability to open it myself. If you could send me the modified STL I will exchange it for the one in the files section so that it doesn't go wrong for anyone else.

Why are they so expensive?

Big fish in a tiny pond. They are bought by industry and if you need one you have to pay what they want. That said, the mechanism that produces the variable-stroke reciprocating motion is beautifully designed, yet fundamentally simple and so very reliable.

Thread: Looking to pay for someone to finish an engine
08/01/2020 23:55:00

Simon I'm sorry to hear about your granddad's passing. My dad passed away leaving a part-built Jinty, but his work had deteriorated over his last 2 years due to medication. I couldn't bare to throw the engine away but didn't see it as viable to finish due to the re-work required so I donated it to the local steam model railway along with the drawings and remaining castings and told them to gift it to someone deserving who otherwise couldn't have afforded to buy them.

My point is, you might do well to find a local steam model society and visit them on a weekend or club night and find a likely candidate there. If you tell us your location you might get some suggestions.

Good luck.

If you're going to get a Biax get a green one. You can at least do something with them if you have motor problems as the motors are used in other tools. The blue ones are unique so you have no chance finding a rotor or armature. The fans have a habit of coming loose and I was lucky to rescue mine when it happened. Your options would be a rewind/repair or make an adapter plate to graft a later motor onto it.

They are super-reliable but worth thinking about.
