Hi Scaffy,
The problem is not with the excallibur, we can test them no problem, it's the Appollo ties which are 350mm long. Our test rig will just not screw out to take it and I have never seen one that can but there must be a simple solution like you say, even some sort of attachment would be fine. I actually wondered if we would get away without testing these as substrate is new and uniformed in strenth and other properties, long shot I know but worth a go.

Hi aom, you are only testing the pull out load between the thread of the screw eye and the timber, you need to install the shortest possible eye (normally 90mm long) and pull test that. The length of the eye is irrelevent in terms of tensile load.
Hi addisupply,
I know I am being dumb here but as it's one piece 350mm in total, we will be testing a 90mm tie that we are not using.
That was as clear as mud.
So what you are saying is we install and test a 90mm long tie, remove it and install the 350mm tie? Surely that would compromise the timber.

The information we gave before was the method required to gain or prove load capability from a base material.i.e. you test with a short eye version without the expense or time wasted kitting out for a long pull test.
The answer you need, depends on the type of installation. Please see as follows.
If you have an existing "outer" skin that is capable of taking the load, you can place the tester on the "outer" skin and pull across the cavity from the "inner" timber frame. If you have a decorative facing, then a metal or timber plate of size larger than the testers leg diameter should be used to avoid surface damage and spread the load. Please note that any movement or destruction of the "outer" skin will invalidate your test result.
If there is no "outer" skin or structure to pull from you would have to use a number of leg extensions to "pack" out the tester from the timber structure, along with a wide plate or use packing pieces that are solid and cannot compromise the test by bending or compressing, once again invalidating your test result.

Has anyone got any technical specifications for the screw in timber frame ties , we bought some a couple of years ago for a job , just gonna use them again on another job but the agent wants to see some tech spec on paper for them
bought them from generation hire an sales an the rep from there said he thinks they got them from apollo fastenings

Hello
Hydrajaws do not supply Ties just the Testers to test them.Suggest you try ADI Supply 01384 483657 or Hilti 0800 886 100 who may be able to give you a spec sheet for this type of threaded tie.
Apollo were forced into liquidation by a court order recently, owing us and other Companies considerable sums of money so you may not be able to get info from them.

Just re-read your thread AOM,
From the training we have received you dont test the actual tie that is in place, you need to do a 'test tie' adjacent to the area of the tie to be installed, test that, then if passed, install the actual tie. Like already said, just use a short tie to test. What your testing is the substrate which the tie is going to rely on. The apollo inserts are single use only hence the need for a sacrificial test. For timber applications you obviously wouldnt use the plug insert.
I stand to be corrected on this if wrong. But this is how I see it.
