Thanks everyone ... yes the legs are splayed about 2" too wide to get through a 'normal' door - I can get it through the front door which is a bit wider but it's the internal doors that cause the problem. They were not red originally - they were plain passivated steel but had surface rust at the bottom so I rubbed them down and resprayed them red to match the rest of the extractor. They are really heavy duty, not like the this pressed steel you get on a lot of extractors these day .. no chance of bending them.
Without the casters it's too heavy for me to move on my own - the only way it to 'walk' it along by pivoting on alternate legs - it's a bit of a beast.
There are also no hand holds to get hold of the thing when you want to lift it to tilt it ... My next job (perhaps not this week !!) is to design and fit some folding handles that will sit inside the U-channel of the legs when not in use and hinge out to a horizontal position when they are needed .. perhaps with some sort of simple (split pin ) arrangement to keep them in place when in use.
On a plus side ... with the casters on and frames in it it doesn't move very much when spinning, it's very stable .. it rotates slowly pivoting around its central access but I've seen extractors that are like untamed bulls when you set them going. I didn't make any effort to balance the frames out in the extractor they just went in in the order they came out of the supers ... I could probably reduce the 'travel' if I had thought of that.
I only had it up to full speed once and I blew one partially drawn but honey filled frame out - it had spun out but was obviously not that firmly attached .. It didn't really appear necesssary to push it to the limit as two thirds speed was enough to dry the frames. It has a reverse and I spun the frames both ways.
Apart from the slight disadvantage of having to partially dismantle it to get it through the door and the lack of handholds ... really pleased with it. Now ... phase 2 of extraction needs to be finished today or I fear it's going to be reasonable grounds for divorce in the household !
