630 forum posts 12 photos	Hi all, looking for a supplier of Helical gears....prefer from stock.... I need a matched pair between 75-100mm about 20-25mm tooth thickness and hardened ... these are to run in mesh one above the other to reverse the direction of the driven gear.....to transmit 2-5hp at varying speeds.....constant load..... this is to drive a camshaft (4 cylinder petrol) in the past they were driven by ally or even fiber gears meshed with a steel one... any ideas...many thanks Clogs
