For some reason Patreon sent me an email about this video today - good timing as I've just 3d printed a pair of snatch blocks. Needed some pulleys to make it easier to open the big garage door for the kids (we don't usually have automatic or motorised opening in the UK) and got carried away down the pulley rabbit hole. So now have a big pile of pulleys and related items, like snatch blocks, to play with and to teach the kids. Think I'll show them this video too.

2020-02-15 19:47:38 +0000 UTCSNATCH BLOCKS! Used them 2 weekends in a row, my Dad and I went snowmobiling the first weekend we got stuck in the slushy snow, and the second weekend some water got into the fuel tank and the snowmobile wouldn't run, imagine that ;), So we double snatch blocked it back onto the trailer. Luckily it died at the trailer...
2020-02-12 20:36:04 +0000 UTCDo you ave any recommendations for the brand or type of snatch block one should by if they just want to have one handy?
2019-12-26 23:01:25 +0000 UTCStop being amateur and get a 3rd snatch block. You'll be able to pull that jeep backwards.
2019-12-12 19:51:26 +0000 UTCI'm getting the husband a snatch block for Christmas. :D
2019-12-12 16:33:01 +0000 UTCNice! I didn't know about snatch blocks.

2019-12-07 05:13:33 +0000 UTCSo i've always kinda known how pulleys work, but now I Really know, and now im thinking back to all the overhead cranes i've ever used and they all have a block and tackle setup to them... Not knowing exactly what was going on, I figured the extra cables were for strength, especially on the 150 ton crane... Now I realize they were for mechanical advantage. I need to get me some snatch blocks...

2019-12-06 23:22:23 +0000 UTCHe needs to link every video he wants to make money from on here since he's selected to be paid per video rather than per month. Wouldn't be surprised if this is automated too.
2019-12-06 02:38:16 +0000 UTCI hope to one day have as much wonder about the things of this world as you do.
2019-12-05 21:38:20 +0000 UTCPrinter is warming up now, can't wait to share this with the kids.
2019-12-05 20:39:11 +0000 UTCGood video. I like how you had your kids do the heavy lifting (literally) lol. I can think of so many applications where snatch blocks and advanced pulley systems are used.

2019-12-05 18:17:58 +0000 UTCCoincidentally, just last evening, I watched this vid: https://www.youtube.com/watch?v=nbMSBw-rzEg ...and although those guys are bonkers, the lightweight snatch block system they demonstrated looks quite compulling. See what I did there? Yeah, I'm not proud.
