What a superb thread this has become. Thanks for all the great posts, I knew a lot of us had these tools but didnt realise quite how many! I still need to work out what i need for this one, but really the first job is a flat belt. Anyone got any experience with these? I have the joiners, just need the belt. I know this type of belt was everywhere in the old days but seems harder to locate now and some are crazy money. I did go through the box that came with it and cleaned up the 4 jaw chuck which is a Burnerd that is Made in England. No key/tool tho. Maybe I can make one? hmm.. I found a bunch of other things in there that I had no idea what they were and this weird thing which i finally worked out what it was when i looked at the original sales brochure (someone looks to have uploaded it to one of those manual sites). Its an American Tool post! Er... Its original I guess but not very useful, yet i expect like all the previous owners i'll keep it haha.  Used these a couple of times, might have what you need. Some of the parts are Chinese seams china makes everything. www.rdgtools.co.uk/acatalog/CHUCK_KEYS__SQUARE_HEAD_-1.htmlThose are cheap as chips! |

Is the linked belt not any good to you Seen on a lot of old lathes www.ebay.co.uk/itm/373472602551Steve Seen a few posts on Lathe forums where guys say that these linked belts are really for V belt applications, not flat. Then someone comes along and says they use it on a flat pulley and its great lol. forums... hahha! |

And as mutts said try imperial sizes in your chuck Ratchet extension bars may guide you 😉 As said it will be a standard size Got a 3 jaw and 4 jaw chuck, different makes and both are the same size chuck key Steve Mine are sadly different sizes, the 3 jaw has much larger 'grabby bits' (yeah Ive no idea what those bits are called the move and hold the work!) and hence larger key hole. Grabby Bits are "Jaws" the back thread is usually precision ground as a set so that they centre the work correctly on a 3 Jaw chuck, usually marked up on each jaw as 1, 2, 3 or A, B, C, not so important on a 4 jaw chuck where in most cases the jaws are set independantly but there are also 4 jaw chucks that the adjustment screw works as one on all 4 jaws. The jaws are fitted to the chuck in rotational order. The square's for the key are all individual to the chuck manufacturer & chuck size but do use regular imperial or metric sized keys. You'll be able to source a key for your Burnerd easily on e bay as they are a popular prescision chuck but I have made keys in the past by welding the correct size key steel to an old piece of bar which if you have key steel handy is easily done. Lots of options to make your own key though.  |

Big subject this.
If you need your work to be concentric with the bit held in the jaws of the chuck (to within a few thousands of an inch) you need to use a independent 4 jaw chuck and dial the work in.
If you need the work to be just concentric with itself, IE you're going to part it off outside the chuck, then a 3 jaw is fine, so long as you don't remove the work from start to finish.
Of course if you're just making a rear wheel spacer etc, it doesn't need to be super accurate & it doesn't really matter.
Best advice is to invest in a dial indicator and a dial test indicator on suitable bases for your lathe & have a play. The run out on scroll chucks will vary depending on the size of the bar they are holding.
As always more accuracy costs more money.

Cost me a few hundred quid a few years ago. Ideal for making spacers etc. I only use aluminium material.  private image hosting |

Some nice kit here!! I rarely used the lathe in the workshop until I purchased the RD! I had this old Drummond brothers unit that did ok, had it limits so updated a Chinese variable speed mini lathe at Christmas, seems good enough. Anyone know anything about the Drummond Brothers lathes?  Lathe by chris tring, on Flickr  cN lathe by chris tring, on Flickr |

I had to Google what a drawbar was the other day 😆
Oh and then which was the x and the y axis
Like being back at school
Biggest mistake I've made is pushing buttons on the dro which I don't have a manual for and feck knows what I've done 🤣

I need one of those pics for the whole lathe! haha. Im slowly reading the 'South Bend, How to run a lathe' manual from the 40s or 50s. Its all Saddles and Swings lol. An example page  If anyone wants to read this, it was a free download from one of those manual sites and i found a few options for it online. Sorry no link, but it should be easy to find. |

Tested a 1/4 socket bar in the 4 Jaw chuck and its a slightly loose, so maybe these are 7mm...? hmm...
Im trying to think of things that everyone has lying around in the garage (like the socket bars etc) that are square and 7mm to try in there now... ideas?

I had to make new pinions for one of my Burnard chucks. I went for 7mm and the chuck key fits OK. I guess 1/4" originally, but plenty of slop.

 These are what I play with on a daily basis so pretty much the same set up as muttsnuts. Don’t use the Harrison 450 much as the 300 does almost everything I need. Also got the slotting attachment on my Bridgeport which is useful at times. |

The thread title is hobby lathes. Is this really your hobby workshop and not a business?
If so, as said I’m super jealous.

On the subject of books (I'm ignoring that lovely workshop above) what do people like / use?
I have a few of those workshop practice series, I find them pretty good, the screwcutting one was useful for cutting a LH Acme thread, and I'm currently working my way through the gear cutting one.
However the book I couldn't be without is my 1955 edition of the Machinery's Handbook. 15th edition. One of the better ones, as it still has Whit and other Brit threads and sizes in it, as well as the new-fangled AF series. Does cover Metric stuff, although in 1955 there's at least 3 different standards, International, German & French.
You can get it as a PDF but at almost 2,000 pages of small type & tables, I find it fascinating to dip into now & again. Maybe I should get out more.
Had to cut a Morse taper a while back, all the info in the book.
