The various goings on in my workshop
Back in July of 2014 I bought a Boxford morse taper 2 chuck adapter. The Boxford lathe uses a 1 1/2″ 8TPI BSF thread, whereas my Mellor uses 1 1/4″ 9TPI BSF, the crests of which are smaller than the valleys of the Boxford thread. The first step was to machine off the existing threads…
I finally decided to start making all of the gears that were missing from my lathe change gear set. The full set is supposed to be something like: 20, 25, 30, 35, 38, 40, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 127. However I am going to make…
My Lathe has a 4 teeth per inch (tpi) lead screw, and the chuck thread is 1 1/4″ 9tpi BSF. According to the screw threading data, I can cut this thread using a 40 tooth drive gear on the spindle, an idler and a 90 tooth gear on the lead screw. There are other combinations…
To date I have not had my Mellor lathe running under power, the motor works and I could turn the lathe by hand, however I was missing a suitable belt to connect the motor to the lay shaft. I have plenty of ‘fan belts’ unfortunately they are all of a similar length, of around 850-950mm,…
Following on from my previous post, I decided to have a go at making a new lead screw nut for my Mellor lathe. I purchased a piece 300mm length of 36mm round Acetal bar from ebay seller diamondengineeringsupplies for £5.99 along with a few other pieces of Acetal that I intend to use for some other…
Everyone expects a certain amount of wear in an older machine, and I was expecting all sorts of issues with my Mellor Lathe, but in most areas have been pleasantly surprised. The tailstock has a 2 morse taper fitting, is smooth in operation and ejects tooling without the need for a tang, which is an…
A while ago I finally moved my Mellor lathe from where it has been sat at the back of the garage since I bought it. Now the bed alone weighs over 200lbs (90kg) even without the saddle and tailstock, so this was not a simple task, especially without any help. First I needed to move…
