Hi Chaps

I decided this year to try and get all of my unfinished project out off the way before i start any more  :med: ,, so i thought i would start with this one ,, as i started it just over a year  ago  :coffee:  ,,, Well my plan did not last long ,, all off five minutes  :doh:  ,, i decided to make the  spindle ,,so i centred a length of 7/8  S/S bar ,cut a start and run out groove for the threading tool ,,, then went to set up the lathe for 16DP ,,,,,,,,,,,  :doh:  no can do ,,,,,,,,,,,,,,, need a different gear quadrant  ::)  , so i made one  :dremel:
 

Gets that all sorted  :ddb: :ddb: :ddb:  ,,,,,,,,,,,,,,,, then spent two hours looking for my swan neck tool holder ,,,,,,,  :doh: no idea whats happened to it  :scratch:

So made another  :dremel:




Great now i can get going  :ddb: :ddb: :ddb:  soi made a start on cutting the worm



Then just as i am nearly finished ,, just as the tool is leaving the end of the worm ,,,,,,,,,,,, crunch  :scratch:
oooooooops ,,,, stripped two teeth on the tumbler gears  :doh:


Luck no damage to the worm  ,,,,,,,,, so tomorrow night i will have to make a couple more gears  ::)

Hi Rob

Bad luck  :(  :( often wondered how those Tufnol gears survive .. must take a hammering when doing intermittent cuts .. I rounded some 1.67" AF hex last year. Abandoned the leadscrew, fed by apron handwheel instead ... terrifying.

What's the t'worm for anyway .. ??
