Thread: Building a workbench
21/06/2014 05:13:08

Those frames from Masters look the same as the ''Rack It'' frames from Bunnings. I bought the Bunnings frames yesterday. They have gone together very well ; everything is very solid and square and there is no wobble at all.

HINT : make sure you have the diagonal bracing on the ends facing in opposite directions otherwise it will not be square. It took me a while to work out my mistake !

Thread: Which drill chuck to use for a Sieg C2 lathe ?
20/06/2014 13:20:19

But given a choice between 1-13mm and 1-16mm, why not choose the latter ?

The tail stock centre which came with the lathe is 78mm long over all.

Might this  this 1-13mm drill chuck be more suitable ?

So just putting planks of 19mm pine under the plywood is not going to do much unless they are screwed and glued to the plywood ?

No, I was worried about the opposite ie. that the arbor will be too long. As you pointed out on 14/6/2014 above, most of the arbors will be too long for the Sieg C2 lathe. But in view of what you have said, I think too long an arbor is better than too short.

I think I will go with the arbor without the tang ; the second one on my original posting. That way I can also use it on a milling attachment should I purchase one in the future.

Okay, I must admit that I am a bit confused here as I have not had a chance to use my lathe yet. I am currently building the workbench for it now.

1. Please explain the use of the drawbar and how it works ?

2. How do you get the drill chuck out of the tailstock when you are finished ? I should image that it would be jammed in there very tightly !

3. Are the drill chucks and live/dead centres only held in place by the friction of the taper and nothing else ?

Sorry for what seem like some very dumb questions.

John : I have been using the Estapol (gloss) one pack polyurethane for a few months now. I have been preparing wooden plinths for model steam engines, boilers etc. I usually brush on two or three coats, sanding lightly between coats as you suggested but I always finish off with one or two coats of polyurethane gloss spray as it is gives a much neater finish than hand brushing....well better than my hand brushing anyway !

Why do you glue the two sheets of plywood together when you screw them as well ? I would have thought that screwing them together would be enough.

19/06/2014 14:29:04

I am currently painting the plywood with numerous coats of gloss estapol.....in between showers of rain. It is always raining here !

19/06/2014 13:15:13

I might put some 19mm thick planks of pine timber under the plywood to give it extra support.

I have settled on a workbench from Bunnings Hardware to hold my Sieg C2 lathe which weighs 40 to 50 KG. Click on the middle photo to see it.

The top shelf is designed to take a piece of 900 X 400 mm MDF board but this stuff rots in the tropical climate of Cairns so I have had the hardware store cut a piece of 900 X 400 mm plywood which is 18mm thick and has 7 layers.

Will this piece of ply be strong enough to support the lathe ?

NOTE : The metal frame is very strong and does not wobble or move at all which is why I chose it over other workbench kits.

Thread: How to machine a flywheel ?
18/06/2014 14:07:13

Who sells 1/4 inch mandrels in the UK ? There are a few companies selling them in the US but their postage rates are exorbitant.

17/06/2014 07:03:25

Should the inside of the flywheel be machined or just leave that alone ? I usually clean up the inside of the flywheel and spokes with a hand file and then polish off with a wire brush in the rotary tool.

Yes, I do have a lathe but it is not set up yet. It is still sitting in its box on the living room floor. I am building a workbench for it which should be ready next week.

Little Machine Shop has a drill chuck (#1148) with a short abor but it does not list the Sieg C2 as compatible although many other mini lathes are listed. Do they sell the Sieg lathes in the US ?

Eric : Yes, I know. But even drilling at an angle of 45 degrees it is still a very tight fit on most of the flywheels that I have purchased.

Which drill chuck do I use for the Sieg C2 lathe ? I know it has a MT2 taper but there seem to be two different type of ends available and I am not sure what each is used for. I want to be able to drill holes in flywheels by mounting the drill chuck in the tailstock.

Here are the two types :

NOTE : I made a mistake in the main title of the question. How do I correct this ?

Is a dial gauge essential to all this ?

Which raise the question : How to drill the hole for the grub screw in the flywheels ? I do not have a drill press so can this job be done by hand or is this not advisable ? I notice that you do not get much room to manoeuvre as the drill bit, chuck, tap and tap wrench come up very close to the rim of the flywheel.

I need to buy some steel to make 1/4 inch axles for stationary steam engines.

1. What type of steel should be used for the axles ?

2. What do you call the flat machined part of the axle where the grub screws of the flywheel make contact ?

What about drilling a hole through the hub and holding the flywheel using a mandrel ? Has anybody tried this ?

Yes, that sounds good. Thank you for the idea. I hope the taps cut better than the dies !

AFTERTHOUGHT : the nut will end up so tight that getting it off may be difficult ?
