Ok now for fixing the clamp set up, what's wrong with it ?,
1: The clamp area is too small to give a stable fix,
2: Its fixed with a dove tail arrangement, one half of which hooks over the back of the bed, whist the other is slotted and your supposed to press this into bed way vee and tighten it down, no way does this pull the steady tight.
3: The dove tail hooks are steel they will damaged to bed ways.
This is it
Quick rummage in my ally stash for some suitable material this is the first bit to increase the clamping area
Drill some and counter sink some 8mm holes in it for cap screws.
Then drill and tap the steady M8.
OK that's the first bit sorted.
Now for the clamps:- put a angle on two nice bits of 75 mm long ally.
Sorry the pics crap.
Then back to the base bit at a suitable position drill two more 8mm holes.
Then with a nice bit of packing clamp so that the angle will pull down on the bed, and with the other end is hooked over the bed with the old clamp, and mark position. (note to self get some transfer punches), drill and tap M8, repeat for the other side.
Thats it Job sorted: when you tighten the two clamps up they pull the steady down onto the bed and because they are ally they won't damage the bed.
All the wobble has gone I will be a lot more confident using the steady now
I can get back to the boiler build know.
Cheers
