A Major Design Error

In this quick update I cover my Home made V twin engines critical design error and how I am going to use Fusion 360 and my CNC milling machine to rectify this fault in a coming video.

That is frustrating, and hard to motivate to strip it again, but probably only a couple hours to strip, a couple to machine and couple to reassemble. You are doing an awesome project here.

[@OddsandEndsMachining]

Thanks, I know from past experience sometimes taking what seems like a shortcut can take longer than doing things properly and/or lead to half arsed results.

[@RotarySMP]

@@OddsandEndsMachining Yeah, I get that as well. When I do just back up a few steps with a disassembly, I am often surprised how quick and easy it was to do the right thing :)

[@rolanddube2169]

Sorry to hear, such is the way it goes when you are the engineer and builder, there is always something. I know you will find a good solution and it will be a great video.

[@OddsandEndsMachining]

Thanks, I’ve already got the solution sorted, not the most convenient but probably the best long term.

Just landed on this channel. A' V twin super cub', looking cool

[@OddsandEndsMachining]

Thanks, the next project will be even cooler

[@metalmessiahmetal]

Even a different chain? Idk if a hapf link or something be thinner

[@Rozycup16]

Beautiful engine 😊

[@OddsandEndsMachining]

Thank you

space out the sprocket.

[@pipereed1]

simple solution.. Make an offset sprocket. you'll need to space the rear sprocket, but its better than machining away crucial material from the engine cases.

[@OddsandEndsMachining]

The case is 12mm thick in that area so 1mm won’t make a massive difference. But that is definitely an option.

[@kwaka140]

Surely stepping both sprockets out 2mm would be feasible? Also, it's not obvious, but are you pressing the sprocket onto the shaft as far as it goes, or are you putting on the washer and bolting it up as this will position the sprocket further out? The "rough bastard" in me says what about just running it and letting it make it's own clearance.

[@OddsandEndsMachining]

Haha, I thought about the rough solutions but It’ll only take an hour or five and it’ll be a forever solution hopefully. The sprocket is retained with a bolt and splined washer that sits in the groove

[@cucumbersonfire]

@@OddsandEndsMachining that's the way to go mate, glad you slept on it rather than attacking the fully assembled motor with the mill... that way lays madness

[@cedley1969]

Or just buy an offset sprocket and space the rear sprocket to suit.

[@OddsandEndsMachining]

I’ve already disassembled it . . . That was an option but then I need a bunch of offset sprockets. Or this is *free and I should have it back together on Saturday fingers crossed.

[@MrJermbob]

Thats not very major. Could be sorted by hand with a die grinder easy az.

[@OddsandEndsMachining]

That was the first thing that ran through my mind . . . Then I stopped and thought that’ll look a bit rough.
