Talk to the people who cut the tooling

An engineer reads every enquiry. Send a drawing, a photo with a ruler, or just describe the problem — you will get a real answer within one working day, not an auto-reply asking you to book a call.

One last thing

If you only have a photo, send the photo.

Half of our first replies are “that part will not feed in a bowl, here is what will work instead.” That answer is free, and it saves both of us a project.
