nice work Bob What kind of tool do you use for the V grooves ? I used a cut off tool in the Armstrong holder , but have problems with digging in and it's a slow process for me. I made some V section pullies for a Industrial sewing machine in order to slow it down ... it worked out great . I used aluminuim stock. Mike

I use HSS bits for the grooves. I start with a 1/4" wide bit and plunge it straight in the full 1/2" depth. Then with the compound at 15 degrees i take some off either side until the vee is centered and the right width at the top. When i make most of the cuts my lathe is in back gear and the gib screws are pretty tight on the cross slide...Bob

Hello Mike,
What specification of aluminium did you use for the pulleys?

As far as I know it was proper spec. turning aluminium... I bought it from that place in Greens road Dandenong ...
I need some more , a length of 1" stuff as I'm planning on making some core plugs for a old Land Rover engine . They used a weird British thread on the plugs . The old LR motors use them each end of the block as well as normal hit in welch plugs . The alloy threaded ones tend to corrode away . The motor has a alloy inlet manifold and the coolant flows through it into the block . The inlet valve is in the head and the exhaust valve is in the motor block :C Its actualy a crossflow design , advanced in some ways for its time
