I don't think anyone has tried both epoxy products side by side but it seemed to me that if there was a difference then I would not be able to tell. I tried marking it with a scriber and used a centre punch on it and both times it was as hard you could wish for.

It wasn't shrinkage, it was the fastened down rail compressing the epoxy slightly.

Maybe nobody has removed their rails to see if the epoxy has moved ? maybe everyone else let it cure longer than I did ? maybe I torqued the rails down harder ? maybe my environmental conditions meant it had to cure longer ?. There are so many variables it's not possible to compare two situations. All I know is it should be left as long as possible after 3 days before fitting the rails, I seem to remember seeing 9 days somewhere but can't find the reference again.

Also I do not see it as a bit of a disaster, this is a DIY solution, it would not be used in a commercial machine (I hope !). The amount of sinking I'm talking about is less than 10 thou. , the sinking was uniform along the length, it only occured along the 'feet' of the rail, not in the middle so was easy to repair using the 5 minute epoxy and an old credit card , even if I had not repaired it it would have been fine because both rails were still in the same plane.

Don't talk daft any sinkage is Bad news and complete disaster.!! . . . Plus if they have sank so how do you know they are on the same plane.? Impossible to say that without some way to measure.

All this said for wood use then this will still be plenty good enough so it wouldn't bother me.

Regards the Epoxy then I agree West is Good and market leader but I've used other Infusion resin Epoxy's with no problems. Believe Rushing was your problem.!!

Over the years I've not had many 'disasters' that could not be recovered from, in fact working in Engineering Maintenance it's not even an option. In this case one method would have been to remove the epoxy and start again but I chose the method I did because that was fine for me, anyone else should choose their own recovery method.

I measured using a DTI from the face of the surrounding epoxy that had not been touched, I have 10mm each side of the rail 'spare'

Same here

I'm sure there are other resins that can do the job as you say.
Yes, rushing was most likely the problem.
