To those of y’all talking about the epoxy, I totally agree. I thought for a while about solutions to that, and I think in the end I’m going to end up filing off or adding a radius to the current situation.
All the solutions that had to do with adding holes to both sides required a level of precision I don’t think we have in our school shop, especially with my skill level added on top of that. Also, that many dowels would have been hard to manage just with the compound errors alone. Thanks for the advice, though, and next time I’ll be wiser.
