Thread: My First Stationary Engine
23/01/2020 13:09:38

I thought a brass piston in a brass cylinder would cause galling ?

Thread: Can we have a really clear distinction between Silver Soldering and Brazing
23/01/2020 00:57:44

I usually call it hard soldering (Australia) and sometimes silver soldering. Brazing always seems to mean many things to different people which is why I do not use it !

Thread: scratch built beam engine
19/09/2019 05:04:11

I would be very interested to see photos and diagrams of your beam engine if you have any.

Thread: boiler making
01/09/2019 11:01:37

.001'' gap : would you describe that as ''push fit'' ?

Thread: Serious question, What is a Mini Lathe?
06/08/2019 04:23:39

My Optimum TU 150 3V could accurately be described as a mini lathe. Anything bigger, I would simply call a lathe. I am currently looking for something bigger but we do not have the large range of brands available in the UK.

Thread: Removing felt lining from wooden boxes......not animal hide glue.
04/08/2019 01:45:40

A hairdryer first then white spirits if that does not work. The hairdryer would probably work as well as hot water if it was hide glue.

White sprits in the UK = mineral turpentine in Australia : is that correct ?

Thread: Does anybody know what this is ?
03/08/2019 13:41:13

....or find out what it is before selling it !

What ever I use will probably damage the timber so it is not worth trying. I wanted to see bare timber ; I always thought the felt linings looked very tacky...even when new. The boxes are not valuable antiques

Thanks Michael. I will remember that for next time.

Thread: Removing felt lining from wooden boxes......not animal hide glue.
03/08/2019 10:08:01

If the box were antique then the felt would probably be glued to the inside of the boxes and drawers with animal (hide) glue. This can be removed with hot water. But if somebody has used a modern glue then what is the best way to remove it ? I want to leave the bare timber exposed if I can get it clean enough.

I would try the hot water first to see how it went.

If the link does not work then try ''industrial machine in a wooden box'' on ebay.com.au

Thread: displacement lubricator
30/06/2019 02:07:45

1. How often should a displacement lubricator be cleaned ie. open the bottom plug and drop everything out then replace with fresh steam oil ? (I am running small stationary steam engines from PM Research and Bengs Modelbau.)

2. I have noticed that there is water that accumulates in the bottom of the lubricator. Should this be dropped out after each run ? Up until now I have been leaving it there with no problems.

Thread: Lathe Speed - What am I missing out on?
19/06/2019 01:49:58

Why do so many lathes (like mine) have speed dials that go up to 2000 RPM or 3000 RPM ? When would you ever use such high speeds ?

Thread: How often do you oil your lathe ways?
02/06/2019 02:49:49

And if your lathe does become rusty (through a combination of neglect and tropical humidity) then what is the best way to remove it from the ways, lead screw, tailstock and jaws ?

Thread: Rulers - my pet peeve
05/04/2019 01:06:22

Yes, I have a couple of those small rules too. I use them a lot...all spaced around the work room where I can easily find/lose them !

04/04/2019 10:04:31

I have to give a plug for Ozito : all my home and garden power tools are Ozito (except the bench drill) and I think they are exceptional value. They also come with a 3 year warranty. How many things come with a 3 year warranty now ? My brother is a sheet metal worker in Perth and Brisbane and he says he sees a lot of Ozito power tools on worksites even though there is no warranty for professional/tradesman use. The guys flog the daylights out of the tool for a couple of years and then go buy another one. For the price, Ozito are exceptional value.

I have always called it a ruler. I shall have to watch my language in the workshop from now on !

Thread: Is it a drone?
04/02/2019 00:14:55

I think that is brilliant but any airport officials watching would be horrified. How would they know if it was a bird or a drone ?

Thread: Parting off tool - straight or angled.
01/02/2019 13:01:07

Why should the rear tool post give a better result then the standard tool post ?

Thread: Round indexable tips.
27/01/2019 04:31:16

What are these round indexable tips for ? I don't think I have seen them before today. Photo #6 :

Why did that link not work for me ?
