My lathe won’t swing that diameter the throat being too small. If I had a big Harrison the picture would be different & so would the size of the workshop. Dividing the disc acutely I can do on my rotary table, although it is a little on the small side for a 280mm disc, I have successfully piloted this system on a scrap disc & the cooling whilst drilling is achieved by a crude but effective “suds system” made by my dad from an old oil can, dribble fed on to the workpiece.
Some might ask why not stump up & buy a system? Its the challenge which excites me; I didn’t need a miniature steam loco but my equipment & skills allowed me to build one (& start a second).
In comparison doing these modifications is small beer in comparison to other jobs, however as you quite correctly point out the same material care has to be considered in a small workshop as in a large engineering concern.
I’m blessed with this kit, being bequeathed it by my much more skilful dad, I’m just carrying on a tradition. And thanks for your comment.

Thank you both. If you were a little closer Cobber & I’d known you had a lathe that could swing a disc of that size (& other things that are of interest) you would be sick of the site of me.
One problem with starting with an original disc of a 160 etc is the positioning of the grooves & drilling. In effect you would be pushing those closer to the periphery where there effectiveness would be reduced unless further work were to be carried out on the calliper position.
I don’t know many of the answers around this & before I start any development I have an amount of research to be done.
There are others jobs in the offing for me to do before the car goes back on the road, so there’s no rush. However once all the workshop jobs are complete the fitting will be little more than a full brake service.
Thanks again chaps.
