I was having a look at the training aid called Pure Swing that has been mentioned here.

This reminded me of a post on another forum (Single Axis Forum) made by someone who went by the handler "Dognut". (Perhaps he is lurking around here?) I bookmarked that post and looking it up again. It was made on November 9 2003. He and I were discussing various ways to use a training aid called Swingyde.

He came up with a way of using it that made it function very similar to the Pure Swing device. I wasn't aware of the Pure Swing back then, but here is a transcript of my post that summarise Dognut's ideas.

I vote dognut's post as the "post of the year", and his idea of using the Swingyde as the "idea of the year".
Dognut's Swingyde idea will help EVERYONE. Not just conventional golfers or SA golfers but anyone who plays golf. It's brilliant. Whilst I have been criticized for calling someone else's work a waste of time, I can't say enough good things about this idea of using the Swingyde. I would strongly urge everyone to buy/steal/borrow a Swingyde and try this.
I have drawn a couple of diagrams to make it clearer. Dognut may want to add or correct anything that may be different to his way of doing it.
Install the Swingyde upside down so that it fits onto the butt end of the club. Here is a diagram.
The Swingyde should be rotated 15 to 30 degrees clockwise from the leading edge so that if you looked down the shaft from the butt end of the club, it would look something like this:
You'll find that the butt end of the grip is a bit too thick for the Swingyde. You won't be able to put the nut and bolt on. Just use a piece of string or one of those cables with teeth on it to secure the Swingyde.
Start with some gentle half to three quarter shots. Take the club back until the hands are around chest/shoulder height. The Swingyde should be barely touching the inside of the left forearm where the wrist watch band is. (BTW, you may want to wear the sweat band that came with the Swingyde over the wrist watch).
Now swing slowly down to the impact position and feel the pressure of the Swingyde on the inside of the left forearm INCREASING. Do whatever the hands need to do to feel this increase in pressure. If you look in the mirror, you'll notice that the back of the left wrist is becoming BOWED. (See picture of Hogan's raised wristbone in his book "Five Lessons" page 102)
Now swing gently through to the mirror shoulder high position on the followthrough. The pressure should have eased off somewhat, but the Swingyde should still touch the inside of the left forearm. You'll notice that the back of the left wrist may be slightly cupped but is still relatively flat. The palm of the left hand should now look somewhat towards the sky (i.e. the left forearm supinated and the left hand turned over).
When you are comfortable with this, try hitting some gentle 9 iron shots, feeling the same solid hand action through impact. You'll find that the contact is crisp.
Just to finish off, let me add that I think dognut's way of using the Swingyde is better than any other training aid or method that teaches you to keep the left wrist flat through impact. The tactile feedback from the Swingyde and the fact that you have to use the correct muscle action in order to achieve the pressure from the SG on the left forearm makes this ideal for learning. No verbal thoughts. Just feel the pressure and observe what you have to do.
This is definitely one for the archives. Well done, dognut.
Jono.
PS. When you really get good at this, you can introduce some fades and draws but rotating the SG a little bit counter-clockwise and clockwise respectively.

I haven't really used this device since then, but after reading about Pure Swing and how Brian uses it in his teaching, I brought it back out again. Here are some pics of the Swingyde installed in this manner on a mini training club.
If you already have the Swingyde, it's worthwhile trying this. I think it's a better way of using it than how it was originally designed to be used. The good thing about it is that you can use it on your own club, however, because you have to use something like a cable tie to attach it to the club, it's a bit fiddly to get it on and off.
