One step forward then two back with the Seal Flywheels!
I managed to get out into the workshop a couple of days ago and carried on with the manufacture of the two brass flywheels I am making for the pair of Seal engines. My session started well enough until I misread the dimensions and removed too much metal from the face! I decided however to carry on with making the flywheel so I could iron out any other problems and also make the tool for the flywheel starting cord. The pictures below show the progress and tool profile.
It is a big advantage to grind your own tools and the profile soon ground. I used the plan to get the correct profile. I took the cuts very carefully and got to depth but the next time I shall use the parting tool to remove more material and then turn to the profiled HSS tool. This should make the process even easier.
I will now have to prepare another blank. Fortunately I still have enough material but will have to be careful.
- Too much taken off – read the wrong label on the plan!
- Decided to carry on until completed. Learn more that way.
- Using the plan to check the profile for the tool tip.
- Flywheel starting cord profile cut to depth
