Repairing damaged back gear teeth?

Hi All,I'm still messing around slowly putting my Marlow miller back together.On advice from Pat Martindale I took the damaged back gear along to mylocal precision engineers shop to see what they could do. Answernothing - joy! Here's the problem: you can see there are two missing teeth on the smaller gear. Thenearest gear cutter/maker place I can find is over 40 miles away and Idon't have the capapbilities (or know how) to cut gears at home.My thoughts so far are vaguely rubbish, one being build up the damagedarea by welding it, then having new teeth cut, I can do the welding butdon't know if I have to worry about the heat affecting temper or suchcomplications, but I can't do the cutting.Two, find another 28T gear of the same diameter. Spin the old teeth offon the lathe, bore the new gear to create an interference fit on thegear cluster, bosh it on and pin it with dowels. Likely hood of findinga suitable size 28T gear, zero.Three, find a replacement cluster, unlikely but you never know. Anyideas on where to start asking?Four, ask you guys for advice!!Cheers,Rob
