Hi everyone,
I just thought I'd share a neat little idea I've been working on for a while. What I've designed is an adapter plate to put your K&B bolt patterned powerhead on to an OS lower unit. This removes the necessity to have a complete new PTO to do the job.
It's made from 3mm 5052 Al plate. The plate fastens to the OS lower unit using M3 countersunk screws, then the powerhead fastens to the plate using M3 cap screws.
I've been successfully running my K&B powerhead on an OS lower unit using an 'ugly' prototype. What you see here is the neater version. It is fully 3D CAD designed. The profile and centre hole were CNC laser cut, and the hole centres were laser punched, then the normal drilling, tapping and countersinking methods were employed.
Take a look in my gallery:

I'm trying to gauge the interest in these to see whether it's worth making a few to sell. This really opens up possibilities if you've got K&B, MAC, CMB, Rossi etc powerheads but want to upgrade to the OS lower unit. I haven't finalized a price yet, as I have yet to decide whether to sell it on its own, or with the required longer flex shaft and M3 screws. But the final cost will be reasonable, to make this a viable alternative to getting a new PTO made.
Looking forward to your feedback.
Cheers,
Dave
