Hello everybody.
Brian H thank you for your feedback and I agree with you I was hoping for better response it would be nice to hear from a person or persons who has built points in aluminium for tips on what to do and in my mind just importantly things to avoid things I've learned the hard way save me doing the same thing. Thank you very much.
Paul Rushmer thank you for your feedback I have come across the existence of Dennis Monk work on this subject but I failed to get back issues but I did find drawings covering this topic from Dennis Monk I have not received them yet so can't comment on the suitability. I found them at Sarik Hobbies thank you very much.
Bazyle thank you for your feedback I viewed the Facebook pages and I'm hoping to find construction using 16mm aluminium thank you very much.
Ian T thank you for your feedback hopefully something will turn out thank you very much.
Martin Kyte thank you for your feedback the article by Martin Evans looks as if he's purchased the points off the shelf I'm hoping to build my own blur radius and angle that suits that particular point thank you very much.
Thank you all once again.
David Roberts.
