I made a 1:10 model of this Ottoman bombard a few years ago. This one was made in 1465, and is thought to be a copy of the bombards which brought down the walls of Constantinople in 1453. This one resides in the Royal Armories Museum at Portsmouth, UK, and I photographed and measured it in 2019. It has a bore of over 600mm, and fired stone balls of over 350kg.
Last used in anger against the Brits in 1807, where it and others like it, were instrumental in preventing a British fleet from invading Istanbul (renamed from Constantinople). How many weapons have an active life of ~350 years?
So I am contemplating making a model at the same 1:10 scale, like the original, in BRONZE. It will have the same shape and size, but will look like and feel like BRONZE.
I still have my original measurements and drawings of the model. So my plan is to print the cannon parts in PLA, taking into account my extra information from the 2019 visit, then to cast it in BRONZE.
I had planned to stop this blog after finishing the Armstrong RML, but maybe , if there is enough interest, I will keep it going for the next project. You will need to let me know if this project will be of interest. Because lately, comments and likes are few, and numbers have been discouraging. And the renewal date for WordPress is approaching. I get it that people prefer videos, but that is not my style. If this written plus photographs style is not wanted then I will not persist.
Sounds like yet another interesting project for your shop John. Your work is impressive in quality and quantity and I always enjoy reading about your exploits.
Thanks for the feedback John.
The “likes” button has been missing from your blog for a while. Comments on your RML project from me would become tedious being full of awe and amazement at your persistence and ingenuity. Please don’t stop blogging.

Thanks Robert. The communications from readers are what keeps me going with the blog. John
Please continue with these John. I really enjoy the photo style
Thanks Clayton. I appreciate the feedback. John
John you are a great Inspiration to us all ,I for one Enjoy your very well documented projects Cheers Bernie N
Thanks Bernie, I do look for and appreciate the feedback. John
Sounds like an exciting next project. What is the function of the rear half of the bombard?
I don’t comment often but I really enjoy seeing/reading about your solutions to tackle hard to hold or tricky to machine parts.
Hi John, I believe that the cannon was made in 2 parts to facilitate the bronze pours, and transport, because total weight was 17 tons. The rear part is the very thick walled explosion section and the front part of course the barrel. They screw together. I imagine that levers were inserted into the crenellations at the front and rear of the sections to accomplish the screwing. And thanks for the feedback! John
I read every post I look forward to each episode keep going. I do not comment much but love to read everything..You have a way with words which I do not so please keep going. Every post is saved so if I need to recheck anything they are all together.
Thanks for that very nice comment John. ps How do you save the posts?
Keep going John, I read, but don’t often comment, as you’re in a league I’m not. Also, having read the blog, it makes a better understanding of what you show on Zoom.
Thanks for the feedback Munro. The curse of podcasters is that they feed on comments and likes. John
Yeah well you know (I hope) that this little duck likes reading your blog.
And as Munro says we get more info than possible via Zoom. Also, videos might be good but one cannot get the detailed info even using pause and rewind from them.
SO! Please keep blogging.
Thanks John. I get the message.
Well John I for one follow all your adventures with much interest and perhaps should press “like” more often.
Videos are fine but you’re picture plus commentary is a conversational style which lets me into your personal world of successes and failures, trials and triumphs, and so my world too.
BTW my condolences to SHMBO on the outcome of the Grand Final. As you know it was probably your fault so buy her some flowers.
I’m a vote for “keep Going”
Love cannons or not, it’s still history and model engineering so I’m in.
Great feedback, thanks Tim. We are both feeling low today, but there was no doubt that the best team won last night. Sad for Ablett, but he had courage to play with a fracture. Martin was awesome. Like Ablett senior in the 90’s.
I really enjoy reading about your projects. Especially the cannons since you’ve taken the modeling to a completely different level than I did. It’s been informative seeing your casting progress and gives me ideas of my own. I also enjoy your steam engines, my first metalworking project was a simple oscillating engine. I hope you keep posting and I’ll definitely be following whatever you build!
Thanks for the nice feedback Jeff.
