I'm thinking of brazing up a new aluminium sub chassis out of 30mm sq box section for the ply base, then simply bolt the Y frame to the underside thru the sub chassis. A job for winter.
Is it possible to convert an 8 speed 11-32T to 10-32T?

That sounds like a fun project - are you intending to use an even bigger board? Or is it to keep your existing larger than normal board completely straight, when loaded with your heavy "The Honey Beesness" stock?
I'm thinking of making a big wooden box for the CF, but instead of bolts to secure it - thick round wooden circular wood plates/cyclinders bolted to the box underside, to fit into the existing board holes. Then straps would be sufficient to keep very heavy loads in place. It'd be a stronger solution than those nubs that CF sell, which you have to drill shallow holes into the CF board to secure. Pumpkins are bloody heavy, also big, even the large plastic boxes are not large or strong enough.
The box sides could then go right to the edge of the board, as they do on the Homcom.
With a bit of luck 18-20 mph the legal 48v 250watt is max current locked via the firmware at 12 amps
can over pedal the top speed
, On the flat but get a hill and it runs out of puff with the 36t on the front it will spin faster

Use the existing base board I made as it is the perfect size for two of my 462mm bee boxes in tandem, the sub chassis wiil as you alluded keep the base board from flexing.
CF XL is now available with uprated chassis and larger base but it still 100mm short for my needs so I will simply mod my one some more.
Mentioning bee's, very sad news today to learn of the passing of Bill Turnball.
You manage to get 18-20mph assisted? That's great! I got about that when I briefly removed the 25kph limit. Two years after resumption of cyling, I can now pedal at 29kph/18mph on the flats after assistance ceases at 25kph. A bad workman blames his tools - the real problem is my weak legs... which are steadily growing stronger (must ask where Lance Armstrong buys his steroids lol). Once my cadence gets too frantic, I may indeed reach for my ebay bookmarks and try the 58T.With a bit of luck 18-20 mph the legal 48v 250watt is max current locked via the firmware at 12 amps

Locating roundalls on the box base to sit in the holes is perfect to prevent box movement, esp for pumps that could move.I'm thinking of making a big wooden box for the CF, but instead of bolts to secure it - thick round wooden circular wood plates/cyclinders bolted to the box underside, to fit into the existing board holes.

The assistance is out at about 17mph even with the speed limiter programmed to max 99kph

He was one of your bee keeping fraternity wasn't he? Bill suffered quite a long illness. Cancer probability used to be 1 in 3 twenty years ago, it's now 1 in 2. I had a tumour in 2000, hoping that'll be all - but random isn't even. Randomness is clumpy. It could strike any of us at any time, and more than once.
Peter which mode do use for the tsdz pas ?
Also even if set to street mode do you find cut off speed is approx. 17mph ?

Oh no, that'll upset the Bafang fanbase! Is it just the bbs01 48v controllers made by Bafang which have locked down firmware, or are third party compatible controllers more amenable to change?
Have given up with the tsdz2 might have tried every trick apart from 52v found not worth the trouble
BT was as he described himself a very bad beekeeper but with his wry sense of homour I expect he wasn't. He developed prostate cancer , Mike Burrows also succumbed to cancer.
I myself am in a high risk category as I lost my mum, sister and mums brother to secondary bowel cancer. I have been DNA tested and carry the faulty cancer gene in my chromosone make up, inherited from my maternal side.

Making the box strong enough without adding too much weight is the next problem - I'm presently thinking dovetail interlocking joints at the sides, reinforced with three galvanised steel bands bolted through all round. Not dovetails exactly, they'll be square. Or I could save a lot of work and simply use the Homcom for pumpkin transportation. To match the Homcom + bike hauling capability, the box can't weigh more than 9.9kg.

The tumour type I had can return even after decades, but it's been 22 years - about 10 more and recurrence is highly unlikely... by which time risks of other tumour types will have risen considerably. It's a matter of blind chance that a random mutation results in a cancer cell which doesn't get killed by the immune system, and managing risk factors. At the moment, gene therapy is in it's infancy, but development appears to be rapid - here's the most expensive gene therapy treatment in the world @$2.8 million:

Making my own plywood using 1mm layers of Balsa with crisscrossing grain, glued together with fiibreglass resin, would withstand force applied from any direction, but will get too pricey - I'll try cheap 6mm plywood first (a tad over 10kg for the box, won't sacrifice too much weight carrying capacity), or just use the steel framed Homcom to transport pumpkins. A few are absolutely enormous.

I might even be able to get away with plywood thinner than 6mm - the breaking strain of these steel bands is bound to be high enough, considering their usual use:

Big aluminium L bars on the side edges, bolted through holding the sides and box base together, plus 6 or so galvanised steel bands wrapped around and bolted through, should form a box strong enough.

A big bespoke box with sides which go right to the edges of the plaform, with longish round feet which fit and secure through the four plaform holes (they could have rotating round discs on feet ends, to secure after insertion - would also reduce noise of flexing platform hitting the underside of the box, by restricting platform movement), could remove the need for a sub-frame?
Depending on the length of the feet - flexing of the base, even by a lot, won't be a problem. Even if the platform flexes and breaks to disengage a leg, the box base should remain attached by the other three securing points, held down by straps passing under the CF frame.
The likelyhood of the plaform breaking at all four points that legs go through it, and/or at the four bolts which secure the platform to the frame, is very low imho.

The best load trailer in the world just got better. The Y Trailer from Carry Freedom has been carrying stuff since 2003. Now available: The new 2.1 Version.

...the box could be made pretty darn tall, capable of carrying very heavy cargo. I recall you found the weight limit of your Carry Freedom Large Y trailer some months ago, while too many carying compost bags, but can't remember at what point your CF's axles worried you.
I'm almost intrigued enough to make such a box, but I have a Homcom and I don't have the time at the moment. Certainly not in time for this harvest anyway. Plus I'm a bity lazy when it comes to making things like that - involves stepping away from the computers...
