Hi Mike,
It looks like you are well equipped to persuade steel into shape and keep it there with those serious looking clamps :clap: :clap:

John

smiffy:
The teeth are cut from 45 x 45 steel bar  . The angle is 30 degrees one side and 90 the other
This is a singe direction gear so only the 30 degree  needs any attention
As I described in post 8 I cut the gears in  a donkey saw

When this is all made and fitted against the pit gear i might have to shape the teeth with a angle grinder , it will depend on how the teeth have worn but it cant be any worse than the one that I am replacing as it was jumping out of mesh due to missing teeth
Photo is the pit gear I will take some better photos this week

hermetic:
Right, gotcha, are you getting two teeth out of one cut?

smiffy:
Yes 2 teeth per piece  but still had to cut over 2 meters of bar . Unfortunately the 45 sq was the only material I did not have and had to buy a 6 meter length . That was a big lump to handle
Apart from consumables ,mig gas and wire etc this is all I have had to buy .

By the time I have finished I will have used about 15 kgs of mig wire and 150 kgs of steel
 Only money spent £80 on the 45 sq bar  and about 30 hours workshop time  A bit different from the £3000 to £4000 quote for a new casting
 
 

smiffy:
Finished the last piece of the cone . The easiest way I find to measure a curved distance is to use a traveller . Blacksmiths and wheel wrights would use this tool to calculate the distance around a wheel and transfer the measurement to a tyre so it could be made to the correct size . I used it to measure the last piece of cone so that I cut the right length
A traveller is a disc with a center pivot held in a frame  , A chalk mark is made on the the wheel were it touches the object to be measured .Count the revolutions and mark the part revolution with a second chalk mark

Transfer this measurement to the piece of metal to be cut . I know most of you will know of this means of transferring measurements but it surprises me how many people do not . 
 
The other photo is just a small selection of G clamps . I dont use them very often now but when you need them they are invaluable .
I often wonder what will happen to all my tools when I no longer need them . The amount of younger people interested in getting involved in this type of work seems to be very small
