Things left to do

Time to step back and put my thoughts in order. Here are the tasks I have left to do and some rough estimates on how long it's going to take me. These estimates are pretty rough, but I'm getting better at estimating my time.

  • Fit headtube - 4 hours
    1. Rough cut frame with Dremel cutoff wheel
    2. smooth out frame with Dremel drum
    3. Final fit with die grinder and possibly file
    4. Cut HT to length with lathe (2 cuts)
    5. Mark HT for placement
    6. Braze in HT
    7. cleanup
  • Fit FD mount - 5 hours
    1. Design miter on DeltaCad
    2. Mark tube
    3. Cut tube & test fit
    4. mount AL box tube alignment piece
    5. Final fit tube
    6. make end-cap
    7. cut tube to length
    8. braze end-cap

    11. finish braze
    12. cleanup
  • Align tube on jig - 1/2 hour

    1. make clamp from scraps of tubing, angle and rods
    2. test fit alignment
    3. make spacer piece
    4. tack
    5. finish braze
    6. cleanup
  • make rear-stay connecting pieces - 2 hours
    1. mark out
    2. drill
    3. rough cut
    4. finish grind/file
    5. tap(?)
  • make lower seat stays - 3 hours
    1. drill relief hole
    2. drill out stay
    3. cut to length
    4. cut end slot for dropout
    5. fit dropout
    6. braze dropout
    7. fit pinch bolt
    8. braze pinch bolt
    9. cut slot
    10. cleanup braze
  • finish chainstays - 4 hours
    1. clamp to maintube
    2. fit lower seat stay connecting piece
    3. braze lower SS connecting piece
    4. tack braze to maintube
    5. finish braze to maintube
    6. cleanup
  • Fit brake bosses - 3 hours
    1. make jig
    2. mount bosses in jig
    3. braze
    4. cleanup
  • Fit cable guides - 4 hours
    1. make helper clamp
    2. plan out cable runs
    3. locate and mark locations
    4. clamp and braze for each
    5. cleanup
That should be about it for the frame. There are a few other tasks like the seat mounting plates and the tops of the seat stays. Not to mention paint. But that gets me pretty much done with the steel work. Total estimate is 28.5 hours remaining. I should be able to get this done by around Christmas, which would be a good thing. I should have it on the road, weather and finances permitting, sometime in February.
