Some properly old school heavy metal

[fastdruid]

Oi my lathe weighs at least 200kg!:smt098

Lightweight! I think mine is ~400Kg! (and is still just a tiddler).

piff this is old school heavy metal my friends

Scariest Pic ever...

I understood the concept of DP with a gun, well after all the stories (which could have just been stories) you kind of figure that maybe once he has at least seen one...

But to see him there, looking about 15 rocking an AK....

[Berlin]

have you bolted on the Voodoo inector yet? :) I hear that takes a bit of doing and you need at leat three people to hold it down to get the nuts on, Its a violent beast!

And I expect to see a full formula 2 sidecar machined from a solid billet before the season starts too! :D

[andrewsmith]

Oi my lathe weighs at least 200kg!:smt098

And the rest!!!

That pic of DP with a AK47 is just a tad unnerving

[yorkie_chris]

Don't worry about Dave, you're perfectly safe if you're directly in front of him.

Weapons like that at 15?
He really is from Northern Ireland then!



Some government officials will be around shortly to discuss from whom you got those weapons and their current location..

Judging by the state of them you've been doing quite a bit of dynamite fishing then. Them's well used.

Should've gone to Spec savers! Whoever sold you those sunnies, robbed you! ;)

[Sean_C]

Must be nice to have your own lathe handy.

I want a universal grinder, they're such brilliant machines.

[yorkie_chris]

Why a universal grinder? They're 'orrible dusty things and AFAIK only meant for finishing operations of couple of (very accurate) thou.

Given choice of tools, hmmm.
Lathe, miller (no room!), AC/DC TIG set (ker-ching!), I think grinder would be pretty far down the list.

One of plans in the pipeline is my own toolpost grinder for grinding tapers and stuff. Pain in the *rse though because you have to guard all the ways against the dust.


Progress update, my toolpost is now at my mate's place getting a couple of mm milled off it so I can hold tools without having to grind half the buggers off.

[Sean_C]

Because I can access manual or CNC lathes 5 days a week and I spend all week on 5 axis machining centres, a universal grinder is the only thing I can't get access to except for at college.

There's just something about them I like- really easy to use, I like setting them up and clocking everything in, then to top it all off I can achieve sky high accuracy and a fantastic finish.

[yorkie_chris]

Fair one, ever used a shaper?

[Sean_C]

Nope. What's that?
Unless you mean profiling the grinding wheel?

[yorkie_chris]

They cut with a scraping action, like broaching a keyway in lathe. Hypnotic to watch as they chuck smoking shavings all over the place lol.

[Sean_C]

I've heard about them. Don't do any of it at my place though.

To be honest I find pretty much every way of changing a material from stock to any sort of part interesting or mesmerizing.

[yorkie_chris]

Ah buggerance.

The missing carriage direction gubbins mean I will only be able to cut left handed threads without a load of buggering about and using a double gear in the middle of the changewheels.

[fastdruid]

Bumholes :-(

Druid

[yorkie_chris]

Not to worry, I will fashion a replacement

P.S big thanks to embee and his knowledge of the dark arts of imperial gearing for making that a possibility

[Sid Squid]

Have you got that piece of junk spinning then?

Very good!!!

[yorkie_chris]

Oi stop insulting my scrap collection

[hardhat_harry]

My motors arrived and a 3" pulley now need to fork out £130 for a 3 phase invertor with speed controller built in and I'll be running. DOh!!!

[hardhat_harry]

Btw got a 5 DVD set of lathe instruction if anyone is interested PM me.

[yorkie_chris]

Right got a DTI (finally...)

Absolutely zero detectable play in the headstock bearings either end, any direction. Carriage has about 3 tenths play in it. Little more upwards on the saddle side, nearly a thou, but since cutting forces here are downwards will it be an issue?

Tailstock has no droop in it that I can see and seems to extend bang in line with carriage (OD of tailstock ram that is, hopefully taper inside is nice and concentric with that).

Having a look down bed with a bit of bar it's not straight, twisted by couple thou over 12". But I reckon this is base not being level and a couple of shims will sort it.

[yorkie_chris]

Heh, welcome to lathe ownership!

What is it btw?

Now you find that the lathe is the cheap thing, tooling adds up rapidly.

You may find http://www.lathes.co.uk/ and then http://www.aluminiumwarehouse.co.uk/ useful. :-)

Druid

Tooling god don't mention tooling

"hmmm could do with a set of collets and chuck, I wonder... :pale:"

That aluminium warehouse place... f*** a duck HOW MUCH shipping charge? It's not bloody depleted uranium.
Local guy has a big bin full of inch ish bits of bar about 3-4" long. 50p each, think I'll grab a bag of those to get me started.

[hardhat_harry]

Well the brackets have been fabricated and the motor is hitched to the lathe

[fastdruid]

I bought an MT3 ER32 collet holder and set of ER32 collets from ctc tooling - http://www.ctctools.biz

Yep, aluminium warehouse not cheap postage especially for small bits but cheap for large bits of aluminium, ebay is good for small pieces but gets expensive if you want more than a small amount. For larger dia stuff I worked out for most things I could buy a 2m+ length from aluminium warehouse, make what I wanted and sell most of the remainder for a profit on ebay (assuming I got the same prices as everyone seems to be selling bits at)....

I presume you've seen http://www.chronos.ltd.uk/ ? They're pretty reasonable for stuff, I bought a replacement 3-jaw chuck from them (when I got sick of the burr on the original meaning it never clamped anything the same twice and damaged things).

Have you decided what size tooling you're going to use? I'm going with 12mm / 0.5" myself. Larger is cheaper second hand as the hobby users can't use it. You typically run into centre height issues with 1" stuff though but if you're grinding them yourself that's not a problem. You *do* have a bench grinder don't you? ;-)

Druid

[yorkie_chris]

I don't like MT collet chucks, threw one at myself at work at 1500rpm or something. When the rest is sorted I'll crack on and make a collet chuck and just by the collet nut and collets.

Chronos is OK, got some measuring kit from them that is alright, some other stuff can be a bit of a lottery.

[fastdruid]

I thought about doing that but was cheaper to buy the collet chuck than try and make one, although I have a nice chunk of cast iron now I could do one from. Plus you'll have to get your screw cutting sorted first! ;-)

Druid

[yorkie_chris]

I'm on with that, just need some bits.* Really don't want to have to reassemble it only to dissassemble it again so hoping I can get away with boring the gears, broaching a keyway and turning a couple of spacers up manually.

*Need 2 sets of 16DP 20t and 30t. Have a big 20 that I can cut in half, and one 30t from a harrison. So just short another 30 and a slug of steel to make the spacer out of and a little bit of brass to make the shifting peg out of.

Can make the spacer and shifting peg at work if you like.

[yorkie_chris]

Hmmm. Turns out I can't actually find gears for it because mine are likely 14.5* pressure angle not 20* as is the usual standard these days.

[embee]

If you can halve that long 20T it'll give matching pairs, then get 2 new 30T ones which will mesh together OK, they don't need to mesh with anything else so presure angle doesn't matter.

They don't even need to be 16DP necessarily, as long as you can get 1.875" centres (e.g. 24DP and 45T if such things exist). Unfortunately 20DP (as on Myfords) won't work, 38T gives 1.9" centres, a bit tight!

Found this thread (http://www.modelgeeks.com/Uwe/Forum.aspx/uk-model/2794/16DP-lathe-gears-needed) , it's a few years old but might be worth a call

Quote - "Do I get a prize for answering my own question ...

I phoned GMB Associates in Tamworth (they are one of the Boston gear
distributors) and they can do 20tooth, 16DP, 14.5PA, 3/4 inch bore in
steel for £11.89, 30T for £15.19 plus UK delivery VAT etc. They have
to be shipped from the US, but they are stock items out there.

Not bad - should get me going OK. They also do 20DP, 14.5PA - 20 to 120
teeth (and 8, 10 and 12 DP for serious lathes)".

[yorkie_chris]

Right I've got that big 20t to split and one 30t from a colchester bantam and a line on another the same, so hopefully tomorrow I can get that gear and machine it.

Cutting the keyway could be interesting, not done one before :)

[xXBADGERXx]

Cutting the keyway could be interesting, not done one before :)

In the bore or in a shaft ?

[yorkie_chris]

In bore.

Basically I'm making a sandwich, 30T-spacer-20T (spacer right size for a selector pin to fit in). But the 20 and 30 need to have keyway to drive the shaft.

Lower gears are same 30-spacer-20 but plain bore to spin on shaft, just a collar to hold them in place laterally.

[yorkie_chris]

Ah BUGGERANCE!

Add a new TIG welder to the ever expanding list of stuff I need :(

[fastdruid]

I want a TIG but can't justify it, why do you *need* one?

[yorkie_chris]

Druid

Making odd bits out of stainless mostly.
To be honest it's only such a "need" because it also does my stick welding duties as I don't have MIG for general purpose use.

Of course it has gone pop when I have a load of crap I need to do with it and the paltry 55amps my little cheapie AC buzzbox puts out isn't going to cut it.

welder trouble;

Any electrical geniuses care to offer an insight other than "it's f***ed that is"

[Icanopit]

Failure = dampness/old age.

Cost effective try this http://www.maplin.co.uk/metallised-paper-rfi-class-x2-capacitors-98166

[embee]

Self destruction of older caps is pretty much to be expected from what I understand, when rather than if. With luck it's not taken anything else out, try a new one, £1.24 from the Maplins link, hang the expense.

[hardhat_harry]

You may be lucky and the cap has gone through old age (not usual for a paper one).

I suspect the diode or power transistor whatever is behind the heat sink has popped and taken the cap out too.

I used to fix tellys years ago and that was the common senario.

[yorkie_chris]

It looks like a diode pack behind it but who knows, I am not good with electronics.
I will hopefully get cap today and see if that cures it. Fingers crossed.

I took the electrics of my lathe apart last night to cut a gert big hole in the cabinet and remount the 'lectrics inside[1].

Decided not to get the angle grinder out at 2am though, for some reason people get all shirty when you do that!

Any of you guys got a use for an indexing head off a milling machine ?

Hi Phil, what size, definately interested.

John I'll take a pic in a bit if I can get it out the cupboard without removing 2 bikes ;)
It's approx 10-12 inches in diameter, I've never used it so not sure it's fully working tbh, should be though as the guy I bought it from was a mate I used to work with, it's proper industrial , weighs a lot .

[Icanopit]

Thanks Phil :p

Having just spent half an hour shifting some 6x3 rsj's over enough to get it out from under my bench.
It's actually better than I thought, whole top part of table turns, obviously indexed, if I'm honest I've never used one to any extent so not fully sure how they work.
Anyway heres a pic, I'm trying to work through my garage trying to find stuff to sell to pay towards my many hobbies and make room :)

Druid

[1] 400 and something Kg.

[Spanner Man]

Good afternoon all.


It's a Colchester Triumph 2000. Made around 1973.

It has a 7.5 inch centre height, but can swing up to 23 inches diameter with the gap piece out. it has 16 speeds from 25-2000 rpm. It'll cut somewhere over 100 various threads, straight from the gearbox, & has more feed rates than an infant nursery.:D

The downside is that with a 5.5kw motor it isn't exactly cheap to run, & the tooling for it isn't cheap.

I sort of 'nicked' it off the idiot who owned it, & gave him £900 for it. including lots of tooling, & several holders for the quick change tool post. Mind you, the £300 for the Hiab lorry that delivered it kinda hurt!:D


Cheers.

There are is a note on lathes.co.uk
An ex-Harrison employee told me that great care was taken to assemble and shim the lathes onto their stands - and that it would be a Very Bad Idea Indeed to disturb this cosy relationship.
Certainly more grief than I'd like to go through in re-aligning the headstock if I was to remove that.

As for the rest of mine it had sat for some years and everything was gummed up solid.

I spent well over a day servicing, & cleaning mine when I got it. One of the most important things is to have a Lathe sitting dead level. I have an engineers level (damned expensive spirit level), & mine has 8 adjustable feet. As my workshop floor is more warehouse than machine shop, I cut some plates from 10mm steel, to go under the feet, & spent a couple of hours levelling it, & then did it again after the Lathe had been run for several hours, & again since.
It didn't half make a difference to the accuracy, One wouldn't think that any machine that size could twist, but they can & do.

On my Colchester the headstock can be adjusted laterally as it pivots on a dowel. This is a DTI & test bar excercise, & again takes a while, but was well worth doing. It now turns over long distances at high speed & feed with barely negligble differences in the diameter of the workpiece.


Cheers.

[fastdruid]

Mine had sat for some while so took a fair amount of cleaning/fettling but for the money I paid was a bargain.

I have some M24 bolts[1], nuts and washers to stick into the levelling holes in mine, I just need some thick metal to stick under them and then some way to lift it (apart from re-assembling the engine crane!) I need a bigger crowbar. :-)

Did you need to do the DTI and test bar bit for checking for twist in the bed after setting it with the level?

[Spanner Man]

Did you need to do the DTI and test bar bit for checking for twist in the bed after setting it with the level?



No, the DTI/test bar excercise comes into it's own when bolting the Lathe to it's stand. Do this first, before levelling the beast.


Cheers.
