Michael, a number of my ancestors were brass finishers, mainly in the Birmingham area.

Small world, Dave

Mine were in and around Birmingham too … one group [the Babbingtons] made bedstead fittings and 'coffin furniture' & the others [Huggins] were the 'tub casters' … On the other side of the family we had people in gun-making and wood-working. The woodworkers ended-up working at that new-fangled Austin car business.

Neil, At Vickers / BAC Weybridge, Coppersmiths worked tubes of tungum, stainless etc and tinsmiths worked flat sheet, Ali, SS and Titanium. Funny how metal working terms were used. Some of the tubes were rather large. I remember working 3" and 4" thin walled stainless and later Jet tubes for the RR Conway engines for the VC – 10. VC standing for Vickers Commercial number 10, and BAC 1-11 was the first aircraft for BAC but the 11 commercial aircraft for Vickers.

Finally installed my newly-turned swarf sampler, and put it to use. This allows swarf samples to be gathered directly from the cross slide before submission to the lab.

A subsidiary benefit is that I dont have to clean the cross slide screw every time I remove the topslide to bolt some other implement on.

Cheers, Colin

This must be in the interests of food quality control. I remember my friend Paul asking the new guy, "What do you want on your sandwich? Jam? Ketchup? Swarfega? You can guess why this was memorable

Had a good afternoon in my workshop only to discover that I'd failed to close a freezer door on Sunday morning and now have a soggy mess to clean up tomorrow.

In compensation I found this website which has some interesting stuff on boilers including how to detect a super-heated steam leak without losing a limb. Also, the accident on the USS Iwo Jima will make me think twice about choosing nuts and bolts more carefully in future!

I have a load of gravel to spread, and the last time I did a nasty to my back shovelling 5 tons around, so knocked up a scoop for the lawn tractor. The metal was mostly recovered from a Telephone Kiosk circa '82 which in turn we are making a book exchange for our tiny village in the 'sticks'.

tried to rotate on an Apple Mac, but couldn't get to anything for correcting the rotation.

I think George Thomas did something similar for Myford, but he used straight spur gears, so it just offset the handle. Radford did one where he offset the whole topslide to get it clear of the tailstock

[Micky TParticipant @mickyt]

I have a need to do some gear cutting so I have started to create a gear hob. I found plunge cutting very daunting but here is my effort so far.

[John OlsenParticipant @johnolsen79199]

I needed to take my Nissan Patrol and my steam launch trailer in for a six monthly inspection, so checked the lights. That's funny, both front indicators are not working, although the ones on the side and back are going fine, as well as the trailer ones. So after a lot of fault finding, I finally establish that there are three faults. Both of the front bulb holders have an internal fault in the ground connection, so the metal bayonet is no longer making contact with the wire that comes out of the plastic housing, and on the left side the earth wire itself is no longer earthing to the vehicle frame. So, not one common fault as one might expect, but three apparently independent ones.

So that was a very frustrating afternoon. Maybe a suitable follow-up to the day before, when a gear stripped in the gearbox on my ML7. This is a Hemingway gearbox, and the gear that stripped was a 35 tooth cast iron wheel that had been adapted from a set of old lathe change wheels. The 20 tooth steel gear that it meshed with is undamaged, so my conclusion is that the loading on these gears is such that cast iron is not up to it. Naturally the gear stripped when I was nearly finished on a tricky internal thread in a blind hole. So now I have to take the job out of the lathe, make a blank for a new gear, cut the gear, reassemble the gearbox, and then get the screw cutting job lined up again.

Open Photos. Select your piccie. Click on 'Image' in the top menu bar – hey presto, rotation options appear.

Today, I learned that 'John Rylands Library' had [yesterday] blogged one of my 'curious finds'.

**LINK** https://rylandscollections.wordpress.com/

This item is curious for two reasons:

• The actual geometry of the two attempts at describing a parabola
• The quite astonishing state of preservation of the artefact.

It seems reasonable to assume that the 'paste-over' was applied at publication of the book [1525], yet there is no sign of it lifting. … The adhesive was probably 'Sturgeon Glue' and I doubt we shall find anything better for such work.

Wow! Albrecht Durer! Parabola, 16th century book correcting technique? Is there no end to your talents? I'm reading 'Five on a Treasure Island'…

Dozer rotated – Had to come away from this site, rotate image clockwise, save it then rotate it anticlock (Back to original orientation) and re-upload to this site.

the talents, yes, but more so the breadth of Michael's interests.

Finally finished the throttle linkage and mounted the fuel tank and primer pump thingy in my brushcutter/whipper-snipper/strimmer/line trimmer (choose which one you relate to) -powered loco. Now to finish the drive train, then the bodywork, then pull it all apart to paint it……….and hope it all goes back together again!

[larry PhelanParticipant @larryphelan54019]

Re Perko 7,

It,s amzing what you can do with a strimmer !!

[J HancockParticipant @jhancock95746]

.Changed the bearings, seal and seat (!) on my '94 Hoover Ecologic washing machine.

It is running so quietly now,

[geoff walker 1Participant @geoffwalker1]

Finished the eccentric strap for my Jepson engine.

All surfaces are machine cut apart from the slit and the small end radius.

My granddaughter popped into the workshop and saw me working on it. "Oooo that's nice Grandad I could blow bubbles with that. She was right!!!! geoff

[Mark RandParticipant @markrand96270]

Does the slot create a reservoir for bubble mixture to allow larger bubbles to be blown? Expiring minds want to know!

 

I got the bridge crane in the shed working to the point that I could start moving all the stuff back to where it was before i moved it to erect the columns and crane rail:-

You've been busy, nice work, heavy duty stuff, phew!!!

Made a start on Brian Rupnows Rockerblock IC engine ,his plans for this engine are superb and are better than any I have used before.He is so helful with information,it gives one a lot of confidence.

Today I discovered that the Chinese have reinvented RS232 with their new breed of RS232 to USB adapters. It seems RS232 no longer requires at least +-3V and inverted TTL is good enough.

Sadly nobody told my Roland CAMM-3 mill that 0V was the new -12V and it is reading it slightly wrong. A definite meander from the desired toolpath.

So now I have to make an adapter for the adapter. Blooming marvellous innit

[Mark RandParticipant @markrand96270]

I thought we had enough problems when PC makers started using 9 or even 5 Volts, instead of the 20 Volts that was expected by older devices… Seem to recall that there were some Maxim integrated circuits that could deal with the voltage shift.

RS232 was always single ended, but ISTR that RS485 was differential voltage levels.

Gosh I thought things stopped being that fussy 40 years ago. Bring back 20mA current loop for machine interfaces
