I guess You can use the guts of a PGM to hubstack an M1. ---

Also, this is one of those “extreme mods” that will void your warranty (if there is one) as well as possibly badly mess up the yoyo. First way: you push down to take the hex nuts out and break the metal or something. Second way: you get them out fine and then the new axle thing is horribly positioned. Other than that, have fun I guess. I would also say that (at least to me and a few others) an L3 feels almost identical to an M1, even though it has a slightly different shape for the rims and is a tiny bit bigger. If you get it from here ([http://www.yoyoz.co.uk/catalog/product\_info.php?products\_id=304](http://www.yoyoz.co.uk/catalog/product_info.php?products_id=304)) (which would be better because the bootlegged things have been taken off) you can get the YYF hubstacks and Dif-e-yo Konkave (C size) you can get it just how it was made, but the real parts. It plays like a beast too. ---

The people at One Drop don’t recommend that you hubstack an M1. This is because unlike the Project, (Which can be hubstacked) the M1 has a round nut (As opposed to the Project’s hex-nut). I believe the first run M1’s have hex-nuts, so you could possibly hubstack them. ---

M1 can be hubstacked but its not recomended because you can dammage it. > **[Page Not Found - One Drop YoYos](https://onedropyoyos.com/404.php)** > > One Drop YoYos is a high-end modern yoyo manufacturer based in Eugene, Oregon, USA.
