I’ve always prefered using Stefans Plans for the pack and Venk71’s plans for the Gun. However, this was before Venks introduced his own plans for the Proton Pack. Either set of plans will do just the trick. I’ve built two packs from wood myself, I already know you’ll enjoy it!
I used stefens plans and venkmans plans your best bet is gather all the info you can and do what you think looks best venkmans molding tutorial is very helpful I made my gun from steel here is some pics 8)
