Please don't ask me why I have so many gears. I bought these over time, always intending to find a use for them but never have! I believe they are all metal lathe changewheels, but might have another purpose

DP here is Diametral Pitch. To calculate the approx DP of a gear, count the number of teeth, +2, then divide by the outside width of the gear in decimal inches. eg 20 tooth gear 1.57 inches wide: 22/1.57 = 14.012, approx 14DP

If you know what machines any of these gears are from, please let me know! If each set of gears does not sell, I will consider splitting them if people need only specific ones. Note that prices quoted above include UK insured postage, which is significant as some of the gear sets are approaching 20kg.

I can accept Paypal or cash on collection from Letchworth Garden City UK (Near Stevenage)

On further research I think the 8DP gears are actually from a screwcutting gearbox, as they are labelled with letters, and only a few of them have the toothcounts on them. I also have not seen any lathes that have 8DP changewheels, the teeth are very big.

The spoked ones look very like the ones on my Boley, if they are they will be desirable for someone.
