This ring pattern is repeated top and bottom, with a depth from top face to bottom face of 60mm.
The top plate is 10mm plate steel, the bottom plate is about 4mm thick.
The top plate is one piece with the handle, so not a round plate ring, with a 380mm handle welded onto it.
Top and bottom ring shapes are welded together using square section 4mm plates, with 25mm holes through them.

It came with 4x M8 bolts(no nuts, so I added 4 to keep the bolts with the tool). Bolt lengths are 75mm overall, 70mm of thread and shank. 25mm of thread, but you don't really need that much thread.
Obviously the protruding thread is only about 10mm or so.
Can't remember how deep the threads in the balancer are, but when I did my flat bar bodge job, I don't think mine went in that deep, felt like about 4 or 5 turns on the two M8 bolts I used.

I kept my old worn harmonic balancer up until this tool got delivered, and it fit perfectly into the balancer, with a very slight protrusion of it's top ring from the face of the balancer.
How that affects the distance between the harmonic balancer to radiator distance, eg. for fitting a breaker bar without removing the rad!) I dunno yet. Have yet to actually use mine on the D1.
That is, I did mine without removing the rad, breaker bar and sokcet went on easily between the balancer and rad. With this tool fitted tho, that could be different, and rad may need to be removed to be able to fit the socket/bar to work the bolt.

ps. sorry about the dodgy hand drawn pic too .. I don't really have drawing/cad type software, and measurements were made with a ruler. They could be out by approx 0.5mm on the small measurements(ie. 9mm bolt holes could actually be 8.5mm or something) and maybe 0.5-1mm out on the larger diameter measurements.

Many thanks Arthur,
With those details I can make something ready for when I need to do the job again.
Just need to add it to the to-do list.....

Thanks again,


Colin
