Nichrome wire distribution lengths

[Sandy H.]

I have 2 spools (around 250ft each) of 34 and 40ga nichrome I want to post for free (+ shipping) in the yardsale forum, but I want to get a good amount to as many people as possible. I have made a handful of igniters myself and know that you use more than you think, but at the same time you probably launch fewer rockets than you plan. So, the poll is to get a feel for the right denomination for spooling this stuff off and posting it for free in the yardsale forum.

Thanks for your input.

Sandy.

@25ft each, 10 people out of each spool can get 34 or 40 ga wire. Might be hard to get 20 people total.

I was thinking the same.

At 3" per starter, 20 feet will make 80 starters. 10 feet, 40 starters. How many rocket flights are being planned for this year? My guess: 40 starters will be more than enough for almost anyone. Except <you know who you are!>

You also don't want to have to ship out more than 20 packages either.

I'm thinking if I just wrap it around a piece of cardboard, I could probably just put it in a regular envelope, so it should be cheap to ship and I won't even have to go to the post office.

Can you wrap it on something like this,

Probably. I was assuming cut up cereal box, but those card things could work too.

Something like a 4" diameter coil would possibly have less kinks thank the cards.

Would be thin in the envelope too.

It would probably need to be taped to a card to avoid the USPS machines turning it into nichrome wool.

I actually did a test of spooling it on a cereal-box card with notches cut to hold the ends and it seemed to work well, so instead of waiting to ship to people because I ordered pre-made cards, I will use random boxes we have here. I think it should fit in an envelope very well, even if 25ft wins the day.

So, pseudo-bump, but new information. Please vote and I'll post in the yard sale forum Sunday.

Thanks!!!

Well, 25ft won and apparently either I'm bad at measuring or Doug used a good bit of it over the years. Either way, I've posted in the yardsale forum, so if you're interested, there are limited quantities available for FREE!

Thanks for the votes and posts.
