Hi guys...I’m looking at my first blaster build and want to go down the pipe route rather than the full Doopys kit. I’ve been researching for a while now and thought I was ready to start gathering the various parts I needed to get started, until....I read a thread stating the use of 38.1mm pipe rather than the 40mm I thought was the standard? Clearly I need to research some more but have a few questions. Firstly which diameter pipe do the Doopys parts and Tino’s finishing kit fit? I have seen that other parts are available from other members too, but again, I’m unsure whether these are suitable for a pipe build or just a Doopys full kit? It’s my first build but I want to make it fairly accurate with a view to another in future with sound/light etc once I’ve got the hang of it. Any help is appreciated...please forgive me if this seems a dumb enquiry but I’m a total noob! Please be gentle:)
