Member postings for Hacksaw

The friend was based in Southampton , I assumed Vospers were there too.  We were actually talking about  thread cutting on a lathe , 2 start threads and stuff .. Disappearing indoors , he came out with a 1" dia bolt and nut , in bronze .. "I made this as a test piece when i was at Vospers"    says he  

It was a   4 start, one turn, over about 4" length  acme threaded  bolt .

"When it's oiled and clean , the nut will descend slowly down the thread under gravity ...."

I'll avoid using my lathe then ,if the river is bursting it's banks in the valley down below . It is most likely why bits i make on it are a bit rubbish

Seeing the seismic thread reminded me ...I was talking to a friend of mine , he had a decent apprenticeship with Vospers in the 70's . Their long bed lathes , really big stuff here , he said, only turned (say a propshaft for example ) accurately either when the tide was in or out ? And certain jobs would have to be fitted in around the tide .. Is that true ?

Quite right Neil , and also utterly off topic , I found this on youtoob.. Rod Stewart & Dennis Law , Angel.

They do look alike ? Jeff beck lives in the next village from me and drives a blue 32 hotrod

The Faces and The Who were renowned for wrecking hotel rooms.. but that's ok ,its rock n roll

Funny thing i've just read ! . On another forum I frequent , a member was wondering what became of his fathers " 5 speed hacksaw " .

It was just an ordinary hacksaw , but the wooden handle had broken ...so it was replaced with the gear knob from an Austin Maxi...

Thanks chaps , i know you'd have milled out a perfect flange to slide and lock the battery pack on .

I'm a cowboy, so i made it from wood, polymorph ,banana skins and bogies...but it works

M.B , D.W . and F .I. thanks for the info on the constant current requirement ..

I have , (by re - using the circuit board bit ) and reconnecting the wires , hooked it up to a 16v drill battery ....And it works !! .. And the drill battery recharges in only an hour !

I've chucked the old battery pack on the bonfire...as its nearly Guy Fawkes night anyway

But the light only runs for an hour or so on the cells and then it's 8 hrs charge ! A 12 v lead acid would run it for ages..

They are bright , no doubt about it , but it's a horrible cold light .. The warm white gu10 led in my kitchen is a much nicer light . I want ideally , to have it on a lead , with croc clips to attach to a 12v lead acid , Just not sure what voltage the bulb would be ..I didn't want to pop it trying !

I took it apart a while ago..having had a rummage i've found the battery ..cells are 3.7v ,i don,t know if they are in parallel or series ...and it unwrapping it reveals yet another i.c.!

And the other end !

Evening gents . A couple of years ago i bought 2 of those yellow portable rechargeable led work lights . A cheap one from Screwfix , and a fifty quid one from the newly opened Led lighting shop.. Guess which one still works ? Yep ,the cheap one !! The other one doesn't charge properly , or runs out of juice quickly anyway.. So rather than chucking it away , and assuming the "bulb" is ok , I thought maybe i could run it on a cable, to another battery ..but what voltage ? About 3v innit for leds ?? After a little dismantling , there's a circuit board in it too.

There's a red wire and a black going to the "bulb" , but connecting them to two AA cells doesn't make it work !! ? Does it need "special electric" from that board bit ? I'll take some photos in a minute .

Also great for when you go out to the dustbin ...and the door slams shut in the wind.. and the keys are in the lock the other side.. Ask me how i know

One of my favorite drawings from "Keep your VW alive"

And kids shoes...

If it tastes mouldy it probably is

I pulled a carpet size piece of "wet and dry " type abrasive 100 grit out of a skip ! Barely used too. 15 ft x 4 ft I guess its for one of those door sanders , where the whole door goes through under the sanding belt... It had a small nick in it ,so i suppose it wouldn't be any good to use .. What to do with it ? Flatting cylinder heads ? Good score though eh ? I did ask before i took it

Slightly off topic , what are those lathe tools that are bent downwards for ? You see them on secondhand tool stalls , usually the last thing to sell , as they're massive industrial size .. They look like they have huge negative rake and would just scrape metal away

If you run out of inserts you can just grind an edge on the holder ,if it's a hardened one , and carry on....

I wouldn't ever do that though.
