A Dremel tool with sanding drum makes short work of enlarging the cut-outs to fit a larger prop.
You used a FILE? Jeez; no wonder you're aggravated. That would take forever.
BTW, I would stay with DuBro. Now that Goldberg stuff is difficult to come by, the DuBro is the best plastic spinner available IMO. Stay away from the SIG on a powerful four-stroke. SIG spinner faces are held only by the two screws; these won't take the torque of a powerful four stroke. The Dubro, like the Goldberg, has four stout pins in addition to the 6-32 bolts/locknuts. Plus, you don't need a hammer to install it or a pry bar to get the face off, like you do with the Goldberg.
My pal broke a SIG plastic spinner on a YS 63, and I broke one on a YS 91; just by advancing the throttle.

Sure.
This a Dubro 2.5" spinner, cut to fit an APC 16x6. I had to remove a LOT of plastic. But if you're careful to enlarge the cut-outs equally on both sides, and only remove as much material as necessary, the structural integrrity of the spinner will not be affected.
I used a standard (15mm in diameter) Dremel sanding drum with coarse grit. You'll be there all day if you try to use the smaller one. They only come in two sizes, that I am aware of.

beatifully done !
Steve, your mod looks great! Very nicely done ! Thanks a lot for the pics and instructions. They give me a clear idea what to do. I don't have a Dremel but I have a RTX with the same size sanding drum. I'll go ahead and use it but wish me luck as I have only one go at it (no spare spinner).................

Bigbri, I heard of many horror stories of SIG spinner breaking up even during throttle up in this forum. Weak design based on two screws holding the nose and backplate whereas Dubro has four dowel pins and two bolt/lock nuts............

Well, how does one one INcorrectly tighten a spinner? Either it's properly fitted and lined up, or it's not, yes?
The two incidents I have personal knowledge of involved four-stroke engines; which have greater torque than a two-stroke. Is that the difference? I dunno.
But a hobby shop owner told me he stopped carrying the product because some of his customers were complaining that they were breaking the spinner with their electric starter.
Now, I know the kind of guy this is; the one who pushes the button, lets the starter wind up, and then jams it against the spinner. And they wonder why they have that ugly gouge groove around the spinner.
Still, DuBro and Goldberg spinners stand up to this abuse, so the point is made. And the simple fact is that the SIG does not have the additional supporting pins.
You pays your money, and you makes your choice...
