Self-Levelling-Epoxy availability downunder in Australia?

The beams holding the rails were then made accurately co-planar using shims on one corner. You only ever have to adjust one out of four corners! I sat the other 3 up on fixed,12mm shims to give me wriggle room in both directions. Making the end result more rigid with epoxy putty makes sense. Thanks for the links to Milliput, I would have tried to use Knead-It which is on the shelf of every Bunnings but sets in only 10 minutes.

Thanks Kit,

In your posts 15 & 16 you have raised a number of welding and alignment techniques that a novice like me can use to great effect.

I particularly like your explanation that you only ever have to adjust ONE out of four corners to get the rails co-planar.

Btw, looking at the scenic background in one of your images, it looks like you guys have moved down to a patch of heaven in Van Diemen's Land. . . . . .

Andy,
As you will no doubt have learned in school, the three corners of a triangle MUST be in the same plane. Therefore when you add a fourth corner to make a rectangle, only the fourth corner needs adjusting to bring it into the same plane. I was so glad I realised that before I started the adjustment. I knew that going to school would come in useful one day!

When I made the gantry I covered the crappy welding with body filler and paint. This time round I decided not to bother. I'm not ashamed of it! It works!


Yes we have indeed forsaken the baked iddyl of Exmouth, WA for the cooler, greener climes accross the Bass Strait. It's a bit of a slope but being on 2 acres means there's nobody going to complain if I run the router, complete with dust extraction, late into the night. Or do my occasional and very poor Jimmy Page impersonation.
