Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.
Author Name is a required field.
Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.
Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.
You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!
Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

Yours is a very informative website. There are a few broken links to other sites, but your site is excellent. I have been programming for over 50 years now, as well as puttering around with much of the stuff you have done. Even if I had accomplished as much, I could not present it as well. congratulations.
And thanks,
Pete

Ian,
I've always wanted to build a 3D printer, it has been a long-time ambition. I probably have all the bits and pieces, one of these days I'll sit down and do it. I think it would be very handy to have a machine that can in principle construct any shape.
The output seems a bit rough in all but the most expensive commercial rapid fab machines, the surface finish is pretty horrible and needs lots of cleaning up, but I could live with that.
The basic X-Y platform and Z-axis tool holder would be very useful for things like milling, not just 3D printing. EDM would be something to try too, it is capable of very good dimensional accuracy.
Regards,
Alan

I'm pleased to have found your site.
I can't offer you anything as interesting from my own resources, as I am not a publisher, but I have found two sites which may interest you (assuming that you haven't found them already yourself.)
Have a look at 'reprap.org' and '[http://www.fabathome.org/ fabathome.org]' sometime and see what you think.
Regards,
Ian

Hello Mark,
My "fuels" coffee grinder mainly. FerroSilicon is a wonderful abrasive, and after about 20 seconds of comminution in the grinder the blades were but stubs.
I made some hot prime with it.
As an spark generator it is very boring, producing only dim red sparks. But as a heat carrier in a prime it works great.
Never did try the Japanese Minium and FerroSilicon prime (which is meant to be somewhat friction sensitive). I just added it to drossy BP-like compositions rich in Sulfur and Potassium Nitrate.
Regards,
Alan

G'day Alan.
So what did you blow up with the Ferro Silicon.
Cheers,
Mark.

G'day RZ, long time no hear!
You never know, my hobbies go in cycles. I get obsessed about something and work on it almost exclusively for ages, then swap to something else, eventually to come back again.
I don't think I'll ever be quite as active as I once was, but I have plans to do something with the Pyrotechniques DB in the near future. While the Pyrotechniques project itself kinda died, the code I developed for it shouldn't be dropped, it had great promise, the composition DB in particular.
To that end, I have recently registered a domain for the project. No ETA at this point, as it will take a little while to write the account management and a suitable UI, but it will happen eventually. I plan to make it a public site that any pyrotechnist can edit, comment, post media, etc. It will be composition-centric, at least at first, so it isn't looking to replace other great resources like the many forums and of course Passfire.

Will you ever get back into pyrotechnics.
