@martynclinton8092 thanks Marty, as for who I follow a few which are similar are. Two stroke stuffing, Rob Dahm, Alec Steele, This old Tony and another kiwi who does the same type of stuff. Ods and ends machining.
Thinking it would be a good time to establish datums, top and bottom, for repeatability of xyz, through subsequent setups. I’m looking forward to the machine work yet to come. What are you looking to use for camshaft cores, or did you pattern it after the OEM? Are you going to run the cam journals directly on the cam bores or incorporate bearing shells? On my own effort, I’m aiming to increase valve lift to .4~.45, valve diameter, with a 88% throat, as that is the point where the the “choke point” switches from the valve curtain area, to the throat. My goal being to achieve / maintain maximum port energy, rather then losing it for going the typical route of larger valves. Looks good, so far, and thanks for sharing.
@georgedreisch2662 Yes the datum points are definitely on my mind, thanks for the tip. Cam shafts will be made from scratch as well, chilled cast iron seems to be popular but thinking about using 4340 if it's possible. Straight on cam bores, not sure I'll have room for shells. Yep 88% throat is what I aimed for on the cad for the same reasons. I need to do some more research into cam profiles but I'd imagine a R6 profile would be a real decent starting point.
Looking good
What a fun journey, we'll done!!
@@KevinBan1 Cheers Kevin
Bloody hell. Top shelf!
Cool
Great series
Cant wait for each one.
Can i ask which other channels you follow?

Really inline with me then…
2strole stuffing

Odds and ends 👍👍
