Pentax K-5 D-BG4 Battery Grip on a K-3, really possible?

Hello all,

I recently found this very interesting hack. If I can save $229, I will be very happy.

Before I hack at my D-BG4 and lessen its value (BTW, my K-5 with <4000 actuations and 2 years left on its Canadian warranty is for sale), I wanted to get some opinions about this hack.

Let me know what you think of this:
Where I found out about the hack: D.I.Y. K3 battery grip

Sounds risky to me. Why not just sell your BG4 grip and use the coin to help fund your BG5?

Well, there's always frugalism, and the natural suspicion which appears when on close inspection a new thing looks identical to an old thing

If the electrical pin outs are nearly identical (seems that there might be one reversed connection), and all I need to do is diminish the diameter of one stabilizing pin (I wouldn't cut it off as suggested), I don't see the risk. What possible risk are you referring to? I have just the right sort of background and skills to take on this as a one evening project. The reason for my post is to find out if anyone has already tried this.

The resale value of the BG4 is probably ridiculously low... it's not like there is a large market for this item, especially when the clone version is just as good as the real Pentax model. YES, it is just as good because I also have one to compare to the OEM version. They are nearly or exactly the same in quality and fit/finish and the clone is only $59.00 (available here: DSTE Battery Grip for Pentax K 7 K 5 D BG4 2 x D LI90 | eBay).

Unfortunately, there are no immediate plans to make a clone version of the K-3 battery grip.

Oh, I didn't realize the clone grips were just as good as the Pentax ones. I thought they were junk.

I mentioned selling the BG4 on here because in a current for sale thread, about 5 people posted in the same day wanting to buy someone's used BG4 grip, myself being one of them.

Granted it was only selling for $70 (including shipping) but I don't see why you couldn't get $100 for it.

The clone grips are good but I wouldn't call it as good as the original.

I have the clone grips for ~2 yrs, the paint on the buttons start to fade within a year a so and the wheel are now no longer working properly. Pretty sure its also not weather sealed.

I've had clone grips that are weather sealed, but the construction quality IS somewhat lower on the clones I've had.
