HHA Little Pull - adjustment

[GeoffT]

Just got my delivery of a LP3 HHA Little Pull back tension release (the wrist type).

I have been adjusting it in the garage and I wondered if anyone else on here has any experience of adjusting one of these?

It would appear to be that it is necessary to pull not too hard into the stops until after the safety trigger is pressed, otherwise it will never go off. It says that the mechanisim should be partly open, but this is not easy to see as if resides under your right ear at the time.

All advice gratefully received.

Geoff, can I ask where you ordered it from.

I'm not sure if this helps, but the Loesch backtension has a safety that has to be pressed when in the valley. The main reason is, if you are pulling too hard into the stops, it will go as soon as the safety is pressed. It then becomes a triggered release. The HHA uses the safety to allow two separate parts to move independently of each other, I think. I guess that a large d-loop attached to a door handle, or similar strong fitting, could be used to pull against and you should be able to see what is going on. If you had fisherman's scales or bowscales you could compare your bow's holding weight with the HHA to see at what poundage things look as described in the instructions.

Hi Steve,

I got it from Keystone Country Store in USA. Shipping and duty were expensive.

If you want a look at it come along to Clayton on a Thursday night. I would be good to meet up again.

Trial and error is the only way I ever found of adjusting the HHA (or Loesch or Evolution for that matter). Its easy in principle, but made harder by two factors.

First, it takes more time and effort to get a consistent holding weight than many people realise - including myself at first. Sometimes the release will go as soon as the safety comes off and sometimes you feel like you're turning purple before it goes, but the release weight is just the same. This is just down to practice.

Secondly, all these releases are affected by temperature, and this is a real effect which I have measured. The Carter seems least affected, and the Loesch most, but all three become perceptibly slower as they warm up (expansion of the sear?), so either get used to it, or expect to do quite a bit of tweaking during a day's shooting.

Yeh - I've got one of these. As Quadratus says it is difficult to get a consistent holding weight. That goes for measuring the holding weight and when shooting So having set it up I did back it off a couple of marks.

In the early stages sometimes it would go off real easy and other times you haul and haul As the thing is quite big for my small hands I find it difficult to hold the safety lever and relax my hand enough to allow my arm to increase the tension to set it off.

The secret is consistency in only pulling enough to effect an steady anchor before pulling more to complete the shot as you have guessed. You can feel it pull open as you draw and then relax when you are setting up the shot.

I certainly couldn't shoot a tournament with one, but it certainly helps reminds your body and mind what it should be doing and therefore well worth working with to improve ones technique and using as a top up every now and then.

Hi Geoff,

I am keep trying to pop a long on a Thursday. I will try again soon. Cheers for the invite.
