Hi Richard,I have cast a number of grips now,I found YouTube to be helpful early on with ‘how to’ type clips. There is some misleading stuff on there to that you have to weed out but it’s good to jump in and learn. Mistakes will be made but it’s part of the learning curve. I am in no way an expert but if you have any questions feel free to ask. If it’s just a one off pair you are looking for I may already have a mould here. Happy to help if I can. Atb Phil
