They are getting big
It won't be long and the next two will be poured. By the time the outer mantle is done they are going to be huge compared to any I have done.bigbells.jpg

You won't be throwing that on the shoulder to move it about, will be good to see it when it comes out of the sand.

Looking good Vin.
I have no experience with it but that looks like a large casting for the investment process.
Have you posted anything on the patterns and making the wax models? I'm interested in seeing the full process if you have time to show it.Cheers, Bob the labrat
Measure once and.... the phone rings!

The process goes like this, design the bell and make a sweep for the inner core and outer final shape. first use the inner sweep and make a loam mould. Once the core/inner is dry coat it with graphite, them with a weaker loam mix apply the false bell using the outer sweep. Allow that to dry and then apply wax using the same sweep. then you add your wax art work and give it several coats of fire clay before applying a thick loam mud over the clay. Allow a time for it to all dry out about 1week in summer. then you fire the whole mould in a wood fire, this totally dries it and melts out the wax. Once firing is done the mould mantel/outer will separate, you then knock the false bell off, replace the mantel, bury in the ground and pour your metal. Simple

And I only have one bell to go and I start building the carillon frame.

Those bells look fantastic, great work vin.
These films show the whole process from beginning to end and just how much work is involved. The voiceover is in German but you can see everything that’s going on.

There’s a few channels with similar content to this that I’ve been watching for a long time. They show a lot of old craft clips from a wide range of fields. Unfortunately I don’t understand a lot of German but that’s never been a problem.
Cheers,
Greg.

The last and biggest
Today I poured the last and biggest bell for the carillon, I was a naughty boy because I felt I went beyond safe level with the A120 crucible making sure I never ran short on metal. I had 122kg of bell metal in the ladle, it turned out I had maybe 10kgs over. I will do some weighing later.
