Something like this maybe?
Its very effective at lifting this 210 kg machine, like using a foot pump for a bicycle, no strain whatsoever.
Could be improved though.
That plate could be spring loaded instead of using a gravity induced hefty plate.
(if you have a suitable spring handy)
I would do this now, as you would hope to get an audible click.
I could either use 75mm castors, instead of those 55mm ones, which I believe might be the solution, must try that soon to see if it works better
or...
Moving the axle that is under the machine a bit closer to the end of the base,
(I was worried that the design might damage the chute of the machine and erred on the cautious side by placing the axle more towards the middle)
I think I can get away with a larger wheel as he chute is around 45 degrees, but it will lift the pedal higher, which is no problem if not in the way.
Why I'm saying so is to stop the feet bottoming out and damaging the floor, as
the height of the machine will depend on the swing of the swivel casters.
As it is, I have to retract the feet which is annoying.
Another one which may or may not be up for discussion...
Making the pedal on the front of the machine would be nicer if in a confined space...
That introduces a whole other kettle of fish to think about,
If the long arm was made of box metal, you could have another 90 degree
bend/joint to bring the pedal around the corner of the machine and put the latch there instead somehow, spring loaded of course.
I would save you having to walk or climb around the machine if you happen to have boxed your self out and share an outfeed table with another machine.
Some food for thought maybe?
