Nice to see you posting videos again. Hope you are well.

[@nedgorski]

Thanks, Bruce. Yep, gettin' back in the saddle after a few slower winter months. A bit of hibernation never hurt anyone..

[@sibashishpaul6681]

Good wishes.. very bery happy to see you back! Infact I was little woried..looking forward to your next post.

[@BlisterHiker]

Always a good idea to keep metal away from metal in fireworking. Nice job. Pozdrowienia!

Neds back!

Good to see ya back, Ned. I look forward to seeing you in Gillette!

The Master at work!

[@louislucatelli4844]

Really nice. I've did hundreds that way

[@countryboompyro6746]

Nice job. Did you granulate your whistle comp? If so is it as simple as granulating bp?

[@FerretyWeasel]

No safety shield? I thought whistle was always supposed to be pressed behind a shield standard practice? Not claiming this is wrong, just curious. I only press BP in my unshielded harbor freight press, but if I could press whistle without spending the coin on a piece of Lexan safely I would do it

[@nedgorski]

I added a shield on that press just the other day, FW. I've only pressed BP endburners on that press 'til now, but decided that once the vid of pressing whistle was done, I needed a shield for insurance. Good point. Thanks.

[@samuelrspade]

Any thought of putting foot controls on your press?

[@vikashrawat1177]

Good job...

Like your club cherry bomb sign ;)

Sir I want girandola composition plss tell me sir

[@DaNiKzz]

Hi Ned , could you please make a video on how to make black powder firework rockets please?

[@nedgorski]

That is lesson 14 in Fireworking 201 on the website, Da...

@@nedgorski ok thank you

[@__djcruzer__8986]

i try these with 7:3 perchlorate and sodium benzoate, my motor was not whistling and didnt go up and it cato in the end of burning....what am i doing wrong?

[@nedgorski]

Any catalyst like copper oxychloride in the mix? That's typically required. And the chemicals need to be very fine, and intimately mixed. We also use a lubricant/phlegmatizer in the mix, such as vaseline or mineral oil, to desensitize the propellant. Whistle mix is very powerful, and static/friction sensitive. Be careful.

[@pyrotekmanfred6503]

Hello , your whistle mix is hard granulated,?it isn’t like rocket whistle mix ?Why? Thanks...

[@nedgorski]

It is a rocket motor whistle mix. Just like I'll use in rockets.

[@aztecworrior79]

Ned where can I purchase that p2f gauge pound reader that sits at the bottom that measures the pounds per square inch, and the clamp shell?

[@nedgorski]

Caleb at woodysrocks.com Certainly an indispensable tool in my work.

@@nedgorski thanks ned your a big help!..

[@timon8874]

What is the composition?

[@আলোরউৎসব-ম৫ঠ]

Sir plss tell me this composition &other wishtel composition

[@nedgorski]

Ranjan, all those details are in the website.I don't get into lengthy discussions of formulas or processes in KZbin.

[@আলোরউৎসব-ম৫ঠ]

Thak you sir....sir pls give your website link description

[@nedgorski]

@@আলোরউৎসব-ম৫ঠ Please see the first few seconds of the video for information, Ranjan.

[@kentherapy7022]

7500 PSI = 517.1 Bar...at diameter 25.4 mm ? = 1.27 x 1.27 x 3.14 = 5,06 cm2 x 517.1 Bar ..Should by total power 2616 Kg ? Is it right ?

[@joeydubbs763]

Why not use a hickory or cocabola (African hardwood, stuff snaps like granite & is absolutely beautiful when sanded & oiled...just an FYI buddy) wood ramrod? They're hard as shit & you take the metal outta the equation all together?...

[@nedgorski]

I have no issue with using metal tooling to make motors, but I just want to do everything I can to avoid pinching propellant between two metal parts.
