Paint does really seam to have got any better, and can still be scaped off with a finger nail. What a waste of 2 tins of hammerite!

Think im going to take the opertunity to repaint it now before I fully assembly the rest of the machine.
Any recomendations for paint?

Also just finishing off the design of some covers. Would some thin 0.7mm galvenised sheet steel be okay?
Little concerned about it rattling.
Plan is to print out some paper templates, cut with a jig saw or scroll saw when sandwhiched between some scrap MDF to stop it bending to much, then fold and pop rivit into shape.

...and covers?, for what?, belts?, etc? 3D-printer can be a friend here for complex shapes.

0.7mm a bit thin - they'll quickly attract, erm, character :) Stainless might be prettier (though altogether harder to work well). Why not standard MS and paint in sympathy with the machine?

I find Hammerite paint very good even without a primer but you have to clean any oil off with a solvent first.

I have never used the spray tin version

Paint?, I'd use some of the hard enamel paints used on the machines of old - check out Paragon paints for something as reassuringly expensive as hammerite, though altogether better!

Did you give it a good stir? I've never had any trouble with Hammerite.

Machinery enamle sounds like the right paint! Going with a tin and brush this time. Never have much luck with spray paints.

Cover on the Z axis will go over the whole thing, like this one on one of JazzCnc machines.

Looks like aluminium from the picture.

Moving onto final assembly at last. Total gave up with paint in the end. After 4 tests with the second tin of enamel paint that all went soft even after drying for over a month, im going for the bear metal look! Its bone dry in the garage so dont see it been a problem.

Y (forward - backwards) axis rails have been leveled and are parallel, and both ball screws are have been aligned with the axis.

Struggling with aligning the pulleys that connect both ball screws to my single stepper. Any tips for getting them aligned would be appreciated.

Thanks
