Confusing, frustrating, front rest problems.

Hi guys,
I will e-mail and call maker of rest and see if he can diagnose and help remedy problem.

But, I thought maybe some of you guys might have experienced this or similar scenario, and have some insight.
So, thought I'd run it by you first. Maybe, an idea or thought that will help me explain, communicate with the maker.

The rest is a D. R. Greenlaw Machining, style A, windage and elevation adj. std. top. Made by Dan Greenlaw.
He has a nice website, if you would like to look.

Now the problem is:

When dialing / adjusting the vertical, the cross hair travels in a serpentine motion, as with a wavy line left to right. This is as much as 5/8-3/4" back and forth from one side of the 25m World target to the other.
When the condition changes and you adj. your windage, then adj. the elev. it will move the windage clear to the other side of the 9 ring. I am using a Sinclair speed screw.

So now, I'm using the windage adj, but, adj fine elevation by squeezing the bag.

Of course, I've exhausted all possible ideas and remedys, I can think of.

Any thoughts you want to share, might be helpful.

Thanks,
Later,
Dwight

Hi Dwight,

It sounds like the elevation screw has a bend in it. That's the only reason I could come up with for it's Axl Rose impersonation during elevation.

I wonder how many people will understand that reference. :)

Put something slick under the rear screw and if the front two are well anchored, your problem should go away. If the point is ground off center to the threads, or the screw is bent, you can get what you have. I have a Hart rest that does something similar, and I use a delrin piece with a center drilled into its top under the rear leg, sitting on top of a home made super foot, that has a flat top. That fixed the problem. In a pinch you could put teflon stock tape on the bottom of a coin and rest the point in the center of its top. Letting the rear point be free to slide is the key. The front two are sufficient to secure the rest to the bench.
 
Hi Dwight,
If you take the speed screw out and put the regular adj screw it. Does it still do it?

Boyd, thanks for interesting response

I'll follow your instructions,and experiment some, and hope for the best.

Thanks Joe,

I'm not sure exactly what you mean.
But, if Boyd's suggestion doesn't work, I'll experiment with your idea in mind.

Dwight,
If the Model A has two brass rods going to the elevation adj. maybe one is bent? Are they the same as the Brass Rods going to the front feet? Take them off and roll them on a flat surface to see if one is bent? Or swap with the front brass rods and use the front rods for the back. Level the rest and try again?

Thanks to all who responded, and tried to help with my rest problem.

I experimented with all suggestions.
I left no stone unturned, that I could think of.

But now, I have given up. I'll simply revert to squeezing the bag for fine elevation.
I'll see how that goes for a while.

I'll probably end-up ordering one of the well known, popular rests that I should of ordered in the first place.

I just wasn't convinced that I needed to spend a grand on a rest.

I want to be satisfied and comfortable with the next one, and be able to have complete confidence that it will be reliable

Please advise. There are no BR matches or shooters anywhere around me that I can find.
The only thing I have to go on is the information, and education, I get here.

Thanks

Yes Steve, Dan returned my e-mail promptly.

You stated you would contact Dan Greenlaw. Have you received an answer from him?

He is as baffled as I am, and was unable to help.

He did offer to give me a full refund.

I do believe he is a good guy and has a good product. I just got one with a bug. I may discover what it is some-time down the road.

Dwight,

If you do ever decide to drop the bigger dollars, I have no doubt you would be surprised at how happy you will be if you choose a Randolph Machine rest, otherwise referred to as a Fulgram (sp.) rest. I have had mine since they first came out in 2000 and would never think of changing it. In fact, mine was only the 5th rest Ken had sold. And since I've had mine I have watched as more and more shooters have bought them making the rest basically the standard amongst BR shooters world wide. The newer models are built under the exact same principles, but are so much more refined then mine.

Another excellent rest that you may want to consider is the SEB coaxial rest. I have never used one, but of the shooters I know who have all love them. They are about as quick and easy at target acquisition as anything out there, plus can be easily fine-tuned to fit whatever your desires. The only thing I hope others will chime in on is their ability to cover the entire target at whatever the distance. The only shooter I know of who use one, and loves it, at the 25 Y/M World Target is DanB. And with his proven record: enough said! If I were to buy a second rest for whatever the reason, I would look long and hard at the SEB.
