|Thread: Damaged Sieg C0 lathe...what to do ?|
They will not accept another return.
I purchase a Sieg C0 lathe last month but when it arrived the base was badly damaged so it had to be sent back. The replacement arrived today and it has been damaged again although the damage this time is only minor.
1. The PCB board is attached to this damaged electricity fixed plate. I do not think I should be replacing this myself but I am not sure. Comments anybody ?
2. This plate is made of plastic ; had it been made of metal this would not have happened. Has it been made of plastic as a safety measure ?
3. Does anybody else own a Sieg C0 ? Did you have any problems with safe delivery ?
NOTE : I am trying to add some photos but I am having problems uploading.

|Thread: Mind the Gap ! How much play in an axle ?|
Should I be using a 1/4'' reamer or an adjustable reamer ?

|Thread: Who makes Steam pressure gauges reading up to 20 or 30 PSI ?|
I would like to fit the steam gauge to the boiler once I have built it. I want to have some idea of what pressure is being generated rather than just guessing.
The Reeves 30 PSI gauge looks good.
Yes, I know it is not necessary but I want one anyway.
I would like to purchase a steam pressure gauge that can read up to about 20 or 30 PSI. Most pressure gauges I have seen go up to about 100 or even 160 PSI. This is not much good if your boiler is only producing somewhere between 5 and 10 PSI.
|Thread: What metal is used for valves ?|
The plans have an exploded drawing with each part numbered. There is a chart on one side with a list of the numbered parts, their size and composition eg. part #10 1 X valve 1/4 dia. brass

I have constructed the PM Research 3BIM engine and will soon be starting on the 7BIM. The plans say that the valves are made of brass but they look more like steel to me.
1. What sort of steel would it be : stainless steel or silver steel ?
2. Could aluminium be used for valves when it comes time to machining my own engines ?
|Thread: Mind the Gap ! How much play in an axle ?|
I have a number of flywheels and stationary engines to be machined and constructed when my Sieg C0 lathe arrives. (The original had to be sent back as it was damaged in transit.) I am going to buy some 1/4'' silver steel and possible some stainless steel to use as axles.
1. If the hole in the flywheel has been drilled with a 1/4'' drill bit then what size should the axle be ? It must be less than 1/4'' otherwise it will not fit but how much less ?
2. Should I be buying 1/4'' bar stock for this or should I buy something larger and machine it down ?
3. What is the best way to put a flat section on the axle so that the flywheel grub screw will have something to sit on ? I do not have a milling machine.

|Thread: Shims for packing up cutting tools|
Why don't all tool posts come with height adjustment ?
|Thread: Does anybody own a Sieg Nano Lathe ?|
I have sold the C2 and bought the Sieg CO lathe. Somebody mentioned earlier that the lathe should be bolted to the workbench rather than use the rubber feet. What is wrong with using the rubber feet ?

Isn't that unusual screwing the chuck onto the headstock ? I thought they all bolted on ? Can you still run it in both directions ?
How does the face plate fit to the headstock ?
Ketan : Thanks for the information. I cannot argue with your evaluation.
Victor : Does the three jaw chuck screw screw onto the spindle ? I am a bit confused here.
Victor : yes, I like the Sieg C0. It does look a better buy and it is not much heavier either. I will find an Australian seller to see what they are worth here. The Sieg ebay seller does not have a C0 which is why I had not seen it before.
Looks good :
Even better with an accessory pack :
How do you fit a drill chuck to the tailstock ? Is this a thread unlike the other lathes which use an arbor ?

Ketan : Have you used one or owned one ? Those reviews are quite old and they may have fixed the problems by now.
Ady1 : I searched this site before posting a new thread but could not find anything otherwise I would have added to your posting.
Has anybody owned or used one of these Sieg Nano lathes ?
There are some old reviews on the internet which were not very favourable but things may have improved since then.
|Thread: How to machine a flywheel ?|
Is it tricky to machine the crown ? I do not really need it on my flywheels but it might be worth trying.
On the castings I have , the flywheel has a gradual slope from the centre of the outside surface down to the sides. I think that this is called the ''crown'' ? Should this be retained when machining the flywheel ? Does it serve any purpose other than for appearance ?
|Thread: Using a die to cut a thread on brass/copper pipe.|
UPDATE : I ordered some HSS dies from Tracy Tools and they arrived yesterday. I have just finished cutting a 3/16-40 thread on some brass pipe : no fuss, no problems, no drama ! The HSS die did the job in minutes.
Forget all about carbon steel dies and always buy HSS.

|Thread: Building a workbench|
Oddly enough, they do not sell the moisture resistant and exterior grades MDF here ; only the standard stuff which does not last long in the tropics !
My kitchen is quite old and I can see that it is made of chipboard. Another poor building choice in this climate !
