What I did today .......... was to completely bugger-up a small crankcase I had been making for a new little diesel model airplane engine, due entirely to a lack of concentration. I was doing an internal operation to provide clearance for the connecting rod, and I made a hole right through the 'case. Oh well, machining keeps me happy!
Picture attached, and for scale the piece is just a tad under 2" tall.

Excellent quality work.
Is that a cam?
Would JB Weld work to fill the hole, or is the bore / crankcase under pressure.
What size thread is that. Very nice.
Thanks for sharing

Ken,

Very nice work!? Sorry about the hole... :-(

When I was much younger, I spent 10 years working for a hobby company.? Part of my job during one portion of my employment was repairing Enya and Weber brand model airplane engines, so I have a pretty good appreciation of how challenging they are to make!

Enya and Webra made some very nice engines. I have flown both makes and I still have a couple of Enyas somewhere.

Ken,

Yes, I realized this morning that it was "Webra", not "Weber".? Yes, they did make some very nice products.? I got to see how everyone misused them when they returned them for repair.? The most common problem seemed to be over-leaning the mixture.
