I've been wanting to cut up my Sportster for a while, but are the walls too thin to cut silicone grooves?
Anyone who has had success with this, help would be greatly appreciated.

It has been done, Luke siliconed my sportster a while back.

most of the older Dif's (without existing recesses) are thick enough for silicone, just be sure to measure before cutting...the old rule of thumb is measure twice, cut once...
also, you'll need to drop the bearing seats by a couple thousandths of an inch just to make sure the edges of the bearing are not exposed since there wont be a sticker there any more to keep the string from slipping into the gap between the yoyo and the bearing...

With Calipers, you need to use a short post or something to reach into the open/outside of the half ... and then subtract the lenngth of the post to get the remaining thickness of the yoyo.
Some calipers come with little posts/extensions for this purpose.
If it's over 0.060" you are good. I suggest not making the walls thinner than 0.025"... and THAT is risky as well.
I don't make silicone grooves shallower than 0.035"... and prefer doing them over 0.040".
Thickness of wall : Depth of groove : Resulting wall thickness
0.060" : 0.035" : 0.025" - super thin!
0.070" : 0.040" : 0.030" - very thin!
0.080" : 0.045" : 0.035" - getting better
If I can, I also dove-tail shallow silicone grooves (bottom wider than the top
Careful! The resulting yoyo will not be as strong as it originally was!
