The plastic calipers are definitely a good idea Marv. I had to measure some rare earth magnets once 2" square and 1/2" thick, nerve wracking experience even with the plastic calipers.
The large 6V lantern batteries are also made up of an array of smaller cells, depending on the brand it can...
An older couple were being interviewed at our church, and when asked the secret of their
55 year marriage he replied with "I try and make sure we go out at least one night a week,
I go out Tuesday nights ,she goes out Wednesday nights."
Hi Chuck
This is my take on the german engine on the john-tom page. I think the plans actually show a steel cylinder pressed into an aluminium finned housing. I changed the valve to be more like the poppins, and made the bearing standards vertical rather than inclined. It wasn't much of a build...
Hi Mike
6/10 is right, but if you leave it as 30/50 it tells you how many holes to move on your 50 hole plate.
So as Marv said, counting the current hole as 0, you move to the 30th hole and that is the required position.
hope this helps, I am a visual learner so sometimes my descriptions are...
Hi all,
Now that my flame eater is up and running, I was hoping to give either a stirling or lamina flow engine a go. It seems that graphite rod is the way to go for the pistons. Does anyone know of a supplier in Australia? preferably in Sydney.
All my searches keep directing me to fishing...
First up apologies for a very poorly kept build log, trying to find time to build let alone photograph
has been very difficult.
Secondly and more importantly a big thankyou to everyone who contributes to and
helps run this site. It is such a wealth of information and an inspiration. Without HMEM...
Another thing I found worthwhile to check on a new machine vice is that the fixed jaw
is perpendicular to the base. After the head is trammed attach a dial indicator to the spindle nose
and run it down the face of the fixed jaw. I had a vice that was running out 0.05 over 50mm, makes it
hard to...
Well I sent in the archaeological team and they unearthed this from page three.
Flu and work don't mix well with trying to build an engine, no matter how simple it is.
Nothing very exciting to show, just the crank and cam
The crank was built up using mild steel rod and brass, silver soldered...
Hi Alan
What size machine are you looking at using the ER40 on?
At my work our mill uses ER32 mainly and we have an ER40 chuck for one operation and it is a very bulky holder compared to the ER32 and the 5/8 clarkson holder.

In a number of other posts I have seen powdered graphite recommended for lubricating flame lickers.
I am hoping someone can tell me where it would be available in Australia?
Or is it possible to use the 'lead' from a good quality artists pencil, maybe a 12B as that would have less binding agent...
Hi Arnold
Nice work so far, I enjoy seeing the mods/improvements you have been making to your machines.
On your last pic I noticed the thread table underneath has British cycle thread on it. Just wondering where you got that table as it looks useful
Cheers

My dad tells the story of when King George V or VI was touring Southern Africa and visited a foundry in Southern Rhodesia.
Seeing some men operating the steam hammer he asked them how accurately they could work it. They in turn asked him for his pocket watch, placed it on the anvil and brought...
