He he he - Hi yah all.....don't buy just yet as RudeBits will have a full adjustable weight sitting just there that could of course do the same job but with the importance of weight and adjustment.
All measured up and with Dave at the engineers......you all knew it wouldn't be long

ETA 10 days but maybe sooner.
Let me know if you're all interested.
ps -it will be 2.5 thick strips with the hole for adjustment all x4 if I rememeber right
