A question for VTL guys


Recommended Posts

Recently my forge broke down. I had to pull the fly wheel off and send it out to have remachined.

 

The wheel is 66" in diameter. What needed to be done is machine out the press fit brass bushing and clean out the bore in the casting minimal clean up. Remachine a new bushing Nitrogen freeze the new bushing to press fit it in the wheel and then rebore the bushing adding grease grooves and extending the preexisting grease lines through the new bushing and minimal cleanup on the shoulder of the wheel to make it perpendicular to the bore.

 

The dimensions of the bore in the flywheel are 8.5" diameter x 16" deep. The bushing with material I supplied had a 6.875" diameter ID with a H8 class fit. The shoulder that needed to be remachined was a 16" diameter.

 

Taking in setup and machining approxamitely how long do you guys feel this should have taken to set up and machine complete?
