Hi again,
I did consider tube, that would be an ideal solution, but it seems 2" tube with 1/4" wall does not exist, seems suppliers go 2" tube (3.6mm wall) and the next size up is 2.5" x 1/4" wall, unfortunately the 2.5" inner diameter is too wide I.E. 63.5mm od x 6.35mm wall this leaves me with a 50.8 ID, I need a 48.8 ID
I was only able to figure I would need to machine from solid to get the needed diameter, unless anyone knows another method? as I am still pretty novice at this.
Essentially I need to mate two pieces together, first is 2" tube machined to 48.8mm finish, I then need a bezel with a OD finish of 53.8 (from 2 1/4" rod) and ID of 48.8 so this part will be a friction fit over the first part, unfortunately I'm stuck with the 48.8mm of the first part as this is dictated by the part's use.
I have a mate who does casting and he has offered to cast me some rings, in an effort to avoid so much material removal for me, but I understand castings will not anodise properly, I already have my issues with the alloy I'm using and anodising, but finding 6063 - t6, which I am advised is much more suited to anodising, is not avaialabe in anything like the sizes I need. Haha, life is so tough. Shame I can't make the parts out of plastic or something, but as the part as a role to play in heatsinking this too is a no no. I welcome myself to the world of engineering & design, fun but challenging - a top hobby  |
