70s Ludwig Bearing Edge Advice

[drumco1547]

Hello-

I have some ragged 70s (mid 70s) shells that I am practicing edge cutting with.

Does anyone know what those mid 70s bearing edges are angled at?

I believe it is a 3-ply drum, it has re-rings. Granitone interior. With a clear re-ring.

I can post images if needed, but thought I'd ask if 70s Ludwigs are known for any particular angle.

I am trying to determine what router bit to purchase.

Thanks all,

Will

The edges are 30 degrees, so you will need a 60 degree router bit.

I use this Amana bit... https://www.amazon.com/Amana-Tool-Carbide-Chamfer-Bearing/dp/B073F87WC4/

But I've also heard good things about this less expensive Yonico bit... https://www.amazon.com/Yonico-Degree-Forming-Router-2-Inch/dp/B07GZW5VCQ/

You'll also need a radius bit for the round over.

Thanks- Is there a particular radius bit you guys are partial to for cutting roundovers?

1/4" usually works
