Vee pullies

If it needs a keyway, it can be done with a hacksaw ! Noel.

Hi have you thought of just turning your own. I needed a new double pully for the motor on my M Type so just looked up dimensions on the web, made a V shaped form tool and turned it with correct bore for motor and correct pully sizes.

The small double one on motor.

Hi, I made one from a piece cut out from an old lorry engine piston, it is a three step one, the largest being 44mm diameter and the smallest being 30mm and the overall length is 34mm. The vee's in my case though. didn't have to be absolutely critical, as they drive a round belt on an old Bonds Maximus Drill. It's held onto a 10mm motor shaft, with a small grub screw in the large and middle Vee, and has never come loose. Like Dave, I used a form tool to cut the Vees.

Regards Nick.

Good morning Nigel,

For this job, the dia would be 60mm, give or take, A section belt, bore 5/8" but not a problem since I can bore out to suit. I never found any problem with grub screws, so that would be fine.

I was just totally surprised at how little was on offer and at the price of those that were, so much so that I am thinking about taking the same road as Andrew and making my own as required.

One time, you just went in and bought whatever size you needed, over the counter. Not anymore, times change.

Should be an interesting project.

Very little showed up from Machine Mart, to my surprise.

Thge mention of pressed steel, mpuleys reminded me that in the automotive world, it was notb unknown the adjust belt mtension by removing or adding shims betweenn the two mhalves to move the pitch line outwards or ineareds. (The original VW Beetle, and i think the Renault 4 used this technique for belt btensioning., so there were probably other examples. )

So you copuld turn up pairs of flanges, with appropriate bores, and face the central area so that when paired the 12 mm width for an A secrion belt results.

For a multi sheave pulley, pairs of flanges can be bolted together. Once this has been done, the bore can be fiunished to size, and a keyway cut.

..any good? - you'll have to bore the middle a bit..
