Hello all,

I have been studying plans for about a month and just recently started a build everything pack. I am going to be working on the [Cyclotron](https://www.gbfans.com/wiki/equipment/proton-pack/cyclotron) & [Synchronous Generator](https://www.gbfans.com/wiki/equipment/proton-pack/synchronous-generator) this weekend and realized Stefans plans were missing a couple measurements.

[N-filter](https://www.gbfans.com/wiki/equipment/proton-pack/n-filter) measurements are almost complete and there is a template for the holes that I found. But i don’t know where the placement is. I could figure it out based on the placement of the cyclotron windows but I am way more likely to screw it up.

[Ribbon Cable Clamp](https://www.gbfans.com/shop/ribbon-cable-clamp) dimensions I have not been able to find as well as placement on the synchronous generator. Again I could probably scale based on other dimensions but I am assuming someone already has all the details I could ever want.

Thanks

Note: I know Stefans plans aren’t perfect but they seem to be the most complete/easily available and I am not shooting for 100% accuracy here.

Well I guess I answered part of my own question this weekend. I drew the [cyclotron](https://www.gbfans.com/wiki/equipment/proton-pack/cyclotron) full size on my mdf and cutout a piece of paper for the [N-filter](https://www.gbfans.com/wiki/equipment/proton-pack/n-filter). Then I did some scaling based on the printout of Stefans plan. From what I can tell the Nfilter sits on the 4.5" radius cirle that creates the upper section of the cyclotron and is located 1.75" from the center line.

Hopefully that makes sense and maybe helps someone in the future. I am still looking for dimensions and placement for the cable clamp so if somebody know that it would be great.

From GBfans shop, I like to know what is the correct size of the [ribbon cable clamp](https://www.gbfans.com/shop/ribbon-cable-clamp) that I need to buy, for an accurate GB1 [proton pack](https://www.gbfans.com/wiki/equipment/proton-pack)?

7/8 inch, 1 inch or 1-1/4 inch?? thank you
