|Thread: 3 jaw runout problems|
If they are removable soft jaws on the chuck they should be turned in-situ to reduce run-out. A special plate should be used while machining the jaws so they are clamped in the normal working position. (do a Google/Youtube search for examples).
|Thread: Battery charger problem|
I was recently camping at a rally and a friend had a re-chargable light (one of the small ones on a head band that you wear) and he did not have the correct charger. Instead used one that had replacable blugs on the end of the power cord that suited the light. It explodes and sounded like a shot gun going off. Pieces of shrapnel everywhere. Luckily no one was close by.
|Thread: Mini Lathe - Chuck comes out of the MT|
I don't have one of the spring loaded tapping guides but use a centre in the tailstock and apply light pressure to the tap, adjusting the tailstock as you manually cut the thread. Once started just tap the hole without the tailstock as a guide.
|Thread: Water level indicator|
Not sure about your engine but some have a float that lifts a rod to indicate level. The full size Fowler TE that I drive just has a dip stick as do many others. On my model I made an external indicator for the water height by making banjo pipe fittings and some clear plastic hose.
|Thread: Cutting tools - what type is most suitable?|
If you are going to purchase a cutting tool, I would recommend the Diamond tool holder made by Eccentric Engineering (advertised on this site). It uses 6mm square and round tool blanks and has a jig for grinding, very easy to get the correct angles for cutting. Not the cheapest tool but well worth the money.
|Thread: collet block|
My mistake above . The 9" Southbend has an adaptor from 3MT to 3C collets.
There should be a serial number stamped on the RH side of the bed. My old Southbend is a model C with flat belt drive pulleys and with the spindle running in cast iron head stock (no bearings). It was build around 1938 and has a 3MT taper and a 1 1/2" x 8 tpi spindle nose.
The lathes.co.uk site does mention that Southbend also made some spindles with a non Morse type taper. My question again, what type of centre is used in the head stock ? Standard morse or something else ?
My old 9" Southbend has a 3MT taper in the spindle and uses an adaptor to accept the 5C collets. Also accepts a 3MT/ER32 collet chuck.
You have said that "its got a funny taper in the spindle". What type of dead centre do you use ? Are not most centres Morse taper. ?

Even the cheaper collets are more accurate than an older 3 jaw chuck. Jaws could be ground to make them run on centre but if the scroll is worn, it will only work for the specific diameter that you ground the jaws.
The Australian code for model steel boilers states that the water gauge shall be connected to the boiler independent of all other fittings, including the steam manifold. Reason being that any take-off of steam to a fitting attached to the water gauge will lower the pressure and will give a false reading in the gauge.
When I started work as a mechanical engineer draftsman (originally draughtsman, sorry draftperson), we used imperial units and a year later had to learn everything im metric. No problem I thought, 1/2" in metric is 0.5 inches. Wrong !
The metric measurement which I dislike is litres / 100 km instead of the old mpg for petrol consumption because 100 is not a base unit and the equivalent metric unit should be km / litre.
I have an ER32 3MT collet chuck along with numerous collets which were bought on ebay. They may not be toolroom standard but good enough for the work that I do and all at a price that will not break the bank.
My lathe, mill and rotary table all have 3MT spindles and the chuck can be used on all machines. Also very handy to take a job from lathe to rotary table without removing it from the chuck. The only problem being, if the collet chuck is being used to hold work in the RT, it is not available to hold a cutter in the mill and I have to resort to different methods. And why I am thinking about getting a second collet chuck.
|Thread: Where to source bronze or brass plate|
Your price for having castings made seems reasonable.
Why don't you make the patterns from wood which is the traditional way of making them. Use plywood, craft wood, plastic or any other material which you can cut and shape. Cost of a pattern could be zero.
|Thread: Any interesting lathe projects for beginners?|
Have a look on Harold Hall's website for projects.
Car accessory stores that sell engine oil also keep hydraulic oil.
|Thread: machine coolant pipe|
Lots available on ebay. Including some with a control valve and magnetic base
|Thread: wire bender|
Special pliers for forming round ends on wire are called "Looping pliers" which are similar to round nose pliers but have parallel jaws of different diameters. Lots of difefrent ones on ebay. And these ones called One step looping pliers. Not sure where you get them

|Thread: Metal Saw|
See prevouse posts about bandsaws
|Thread: wire bender|
Have not seen a cheap shop bought wire bender but lots of simple benders shown on Youtube.
|Thread: Cheapskate Sandblaster|
Sand should no longer be used for blast cleaning unless proper breathing aparatus is used, not just a mask. Sand contails silica and breathing it is bad for your health. Workers who breath in silica dust could develop chronbronchitis, emphysema or acute silicosis.
The latest health warnings in Australia are for stone masons and kitchen workers who cut and grind granite benchtops and breath in the dust. They have developed similar lung diseases like emphysema.
The wet blasters do not make as much dust while operation but when the slurry dries, fine dust is left on the ground. We had a full size engine blast cleaned outside of our club shed and although there was no dust while cleaning, when it dried the wind picked it up and blew it everywhere. Do the blasting on top of a plastic tarp and roll it up with the damp grit and dispose of it before it dries.
