|Thread: Boxford AUD motor drive wheel plus reverse switch issue|
This might be useful link
Taking the motor out may be the best way to solve the key issue.
There are variations in the switch gear and a picture of just what you have may be useful.
As for an inverter not sure that would be worth the expense as you'd need to change the motor as well.
My AUD has been faultless for a number of years and it has done a fair bit of work.
|Thread: 3 phase cable for a VFD|
I used SY cable and also have a RF filter on mine all fitted in a cabinet
|Thread: DRO Flashing|
Or the new battery is past it's best.
|Thread: Central heating woes.|
As I found out when it tripped the RCBO on the boiler feed with water in the motor.

Rad sealer will not work where parts move like diverter valves.
I'd be inclined to investigate just where the leak is, it could be something like the diverter valve if it's a combi boiler.
Once the location of the leak is identified and the faulty part found, you should be able to order the part online. Then get a few tools out and replace it having drained down the boiler first.
There are many videos on line that show how to replace parts so not that difficult to do and before there is the outcry of gas safe, it's not a gas issue just water side.

|Thread: Boxford C Lathe|
If you look at the two pictures I posted it shows the gears set in either direction, as I have a AUD the forward and reverse probably gets used more for saddle or cross feeds rather than cutting threads. Feed options are not available on a CUD.
Why would you want too reverse the lead screw unless you were cutting a LH thread?
I usually just quickley wind the tool out (noting the depth of cut) and stop the lathe, then depending on the length of thread either, leaving the lead screw engaged, wind back by hand or carefully reverse the machine taking noting that the chuck is screwed on.
If we are talking about reversing the lead screw then the reversing system is quite simple.
The double gear drive on the lever pivot about the shaft that shows two gears, there are three positions fwd, neutral and reverse. In its current position the headstock shaft drives through the left gear and then to the right and down the gear train. In the opposite direction the left hand gear becomes redundant and drive is direct from the right hand gear.

|Thread: Soft jaws|
How many here use soft jaws to hold parts in a lathe?
I've used them in to machine multiple parts as it means there is repeatability.
|Thread: Holding End Mill on small lathe|
Some mini lathes do not have a full depth morse taper in the headstock but if yours has I'd opt for a MT1 ER 25 as the range of collets is larger than ER 16. My Boxford has an ER40 on a back plate but it is a bigger lathe.
|Thread: New lathe|
Ask away, owning a 5" AUD for quite a few years I know it fairly well.
I have a late 5" metric AUD so my answer would be go with the Boxford.
|Thread: Speedometer Ratios|
It might be worth speaking to Speedy cables as they can recalibrate speedometers **LINK**
|Thread: Cylinder bore measuring|
|Thread: Basic battery charger|
Just place a good battery in parallel for around 1 hour.
Compressor output is usually quoted as x cfm but often miss the last bit "free air delivered" or running at atmospheric pressure.
|Thread: To use chuck or collets|
You can get a collet chuck with a Myford thread as I have one on my Dore Westbury milling machine Also have an ER40 on a back plate on my Boxford which I tend to use over a 3 jaw chuck with round bar.
