Could be pre-drilled to 7 mm, would make them lighter for shipping. Gathering your ideas before starting to sell them. We are based in Lao PDR so postage costs are something I have to work out carefully. Thank you for your thoughts, GuyNever really thought about it! I suppose the round ones give you a closer iepdea of what you will end up with but I usually start off square and the. work out which is the best angle of drilling to get the feature I want. Square gives you that choice provided you can drill straight and accurate enough.
Or am I missing something? do they come pre drilled, say 7mm to be opened out if necessary with a wider drill or. reamer?
Glad you like them, I'm impressed and I cast them! Hopefully I will be offering them for sale once I have worked out the logistics, thank you for your thoughts, GuyI prefer them round, depending on the price difference. They look fantastic and am interested in buying some!
