GOOD NEWS: Hipshot links to a dimensional drawing of the roller nut on the website.

BAD NEWS: The drawing doesn't match with the actual dimensions of the two roller nuts I've purchased.

I received a reply from Josh Borisoff (Hipshot).  They have republished the roller nut dimensional drawing with the correct dimensions.  The new drawing matches the parts I have:

Thanks for hounding this.  You did many future shoppers a huge favor, whether they realize it or not.

Just to be clear, they hadn't actually changed the design of the roller nut, correct?  They simply had an incorrect drawing posted up until your emails prompted this correction?  That's the way I read this.

I'm about to purchase another myself...

Jamie:  That is correct.  The current and past roller nuts match the new drawing.

Roger that, thanks!!

Thanks everyone for the information, DoubleShot is a great thing, I can’t imagine my dobro without it.

If anyone is interested, here is a copy of my answer at the Jerry Douglas mmmlearn.com forum regarding the installation and using DoubleShot:

Hipshot DoubleShot has been on the market for a relatively long time, but there is still not much information, especially regarding the setup and long-term operation of this device.

Of course, if you have the opportunity, it is best to install and maintain the DoubleShot at the Paul Beard workshop. I had to go through trial and error myself, but it was a rewarding experience. 

Here are a few of my observations:

1. The roller nut has a fixed roller height, and it is not suitable for some wire gauges. I use John Pearse 16-59 and in order to achieve a uniform string height, I had to order replacement rollers from a turner. Although it seems that Jerry is not at all bothered by the uneven height of the strings, judging by the video with Jerry and Paul Beard here at the site =) 

2. The Fishman Nashville pickup in my dobro survived 10 years of use with the DoubleShot without any problems. I came across a mention that the upper part of this pickup (I mean the second version) is made of GraphTech material, and this explains a lot.

3. When installing, it is very important to fix the base of the DoubleShot firmly on the body so that there is no gap between the guitar back side and the DoubleShot. Otherwise, the system will be unstable, and in a closed position, the tuning may be inaccurate every time.

4. The same is with the location of the cone in the well - the whole system should make a straight line. In my case, the neck was set slightly at an angle, so the strings pressed and shifted the spider and cone to the side over time. This, of course, affected tuning.

5. Check all bolts and connections every once in a while, this is important. On my system bought from eBay in the UK, the screws were not tight and this led to poor lever locking in the closed position. Finding and solving the problem took quite a long time. 

6. The part with the rubber roller under the back of the "bridge" should be slightly angled to the left. It's hard to explain without a photo, I'll try to attach photos later.

I'm a little late this thread, but I wanted to add info for anyone installing on a Wechter Scheerhorn. I bought the double shot and roller nut and installed successfully with the issues mentioned here, but I bought different locking tuners. I figured out that the stock tuners are Jin Ho tuners. I searched for Jin Ho locking tuners and found them on ebay. They fit perfectly without drilling or filling any holes. So far so good. Probably not the best quality but I'm happy with them.
Cheers,
Dave
