Stuff you have made today

[Hood]

Indeed, Churchill precision machines made weapons for Saddam under some dodgy deal with the Major government...

Mine predates that quite a bit, think it is a 1985 machine. It is actually a Polish lathe, Tarnow SN.
Churhill bought the base machines and fitted ballscrews etc and a CNC control, GE1050 was on mine when I got it. It was like new and it was reckoned it had done about 40hrs work.

Made a lot of changes to it since then including making a few different turrets, the latest being the VDI one in my avatar.

I would not like to rewire that!

I would not like to rewire that!

It wasn't that hard, the control and HiAks were not there when I got it as I bought it in conjunction with a friend who wanted the HiAks for spares for his machines. Cost me £300 for the lathe Here it is on the trailer.

This is a pic I like, gives an idea of the scale of the machine, it is a Colchester Triumph 4 way tool post sitting atop the Computurns 4 way toolpost

Remember this?

I made this today (well yesterday but I fitted it today). Just a bit of 12mm thick flat bar with a bit of pipe welded on the end and a bolt hole in the other, a rubber bung down the pipe to hold the jet tube to dampen vibrations and hooked it up to a diesel jetwash bowser.

It's for keeping the dust to a minimum when breaking out concrete. Site were so impressed with it they gave me a voucher for a free breakfast

Well, the site team got to hear of it and were so impressed they gave me man of the month award and a £100 voucher

Finished a trammel I've been on with past few Saturdays. Top knurled bits rotate with your hand, held with circlips. A trivial addition maybe but the whole thing has been an exercise in turning which I've just gotten into

Lovely job!

 

[God mode restorations]

Am trying to make stuff today...bolted bits back on temporary just to see how bits line up...all good at the moment.

 

[God mode restorations]

But there is one little mistake I didn't notice and it bugs me...it's on the new arch...you guys might spot it...

Made a front bumper bracket...

Do you not think the impressive (and it is very impressive) work you are doing would be better suited as a project thread of it's own in the automobiles section, I fear it gets diluted here and not as easy to follow from start to finish.

Just a suggestion and your choice of course.

 

[Seadog]

Can you tell what it is yet?

Now?

Warm?

Come on...

Surely you've got it? No?

3 hours work, but at least I got to use my new Boxford dividing head. Very bouncy, small lathe, lots of flex, too much feed, hence the dodgy hex. But it does the job and my mate's chuffed
Oh, and it's an adaptor for a Transit jack if you can't tell from the last picture. I just thought it was about time I posted something useful

Good work.
Bet it was fun.
Beats my method of welding on a old 19mm/ 3/4af socket onto the end.

You are correct...I forget sometimes to put pics in other thred

That could have been a possibility, and well spotted that it was 19mm However, you haven't seen the state my welder is in at the moment. If I get it back together it will be presented as a thread. Watch this space, but don't hold your breath

That jack adapter puts my one bit of machining today to shame: a 100mm length of 10mm dia. raw aluminium rod, drilled and tapped M6 x 20mm deep both ends.
It's an extension to allow a digital DTI, hanging off a height gauge, to reach into the bore of a 155mm artillery shell to measure some spark-eroded simulated defects.
The defects are (supposedly) 0.2mm deep and 0.2mm wide by 20mm long, longitudinal and circumferential.
Tolerance on depth is 20 microns - trouble is, spark erosion leaves a surface finish like the dark side of the moon so the DTI stylus can find the highest or lowest points that are themselves more than 20 microns apart!

 

[gordon stephenson]

20 microns heh, Ian, off the top of my head that is around four fifths of a thou, Good going,

Can I ask.....why?

Made this OTT flywheel puller for the old Dolmar having failed miserably with an old weaker cobbled together version when the M10 center bolt sheared.

It's definitely rough and ready - I need plenty more practice on the lathe but it's functional and that's the important bit for me. With no suitable stock to hand I welded a 10mm plate to a section of 25mm round bar before turning. It took more time tapping the 1/2" BSW thread (just happened to be the only half decent bolt I had to hand) than the rest of the job put together. Bolted it to the flywheel and got prepared to give it some welly with a 15mm ring spanner and 1/2 drive socket with what happened to the old puller in mind. I hardly had it even nipped up and it popped off as it should - a bit of an anti-climax really but I'm happy that it's off and I can no tackle the repairs to the flakey Bosch Ignition Module.

That is what it is all about, good job well done I say

 

[gordon stephenson]

Good job man, Solid,funcional, does the job required,

Can I ask.....why?

Of course you can

One of our clients is a manufacturer of ammunition; the process of making each shell is quite involved and there is scope for stress fracturing of the casing. So after forging and some initial machining work the shell is put through an ultrasonic and eddy current inspection process that looks for surface-breaking and sub-surface defects. Obviously the smaller the defect you can find, the more dud shells you can reject.
In order to know whether the inspection system can actually 'see' the defects they periodically (about every 10 shells) run a calibration pass whereby a shell with known faults is checked. If it fails then the next batch of shells can be processed; if it passes then production stops and the last batch must be suspect.
This is an older system so it's all done with rollers, belt drives, proxy switches etc. but our last system uses a Fanuc robot about the size of your arm that can trace the outline of the shell (smaller ones, 4", 105mm etc.) while the shell rotates on a spindle. The whole line is automated and runs 24 hours a day making lovely projectiles that we can lob at those who offend our Sovereign - and not many fail. Ideally you want them to fail at this stage rather than when it's in the breech and Johnny Gunner presses the tit, or mid-flight when Achmed Al-Gunner is throwing the same things back at you from his Russian-built main battle tank...
