Help

I have hit a brick wall doing the cam for this small part

I have 6 mm flat and bull nose

dito 3 mm 

I intend to drill the holes at 4 mm to start and bore to size 

its the slope that is messing up , and most other bits I have deleted my feeble attempts so not to muddy the water

its a crank arm for a beam engine

Did you model this part yourself, or was it provided to you? Is slight modification possible, simply to clean it up? Talking about adding fillets and smoothing out the surfaces:

[Stuart-H]

I modelled it up my self look like I made a duff job I will correct the points you mentioned

any mod are possible the only important bits are the two holes , crank throw 

thanks for looking
