Ok so started on the gun a couple of days ago ( you probs have seen the pics)
the main barrel was easy long plastic reinforced tubing about 16" in diameter.
the hardest part was the drop at the end of the gun tried many things but none worked until recently . got 3 long tubes about 3/4 " in diameter cut two down and left one its full length then taped these together then placed the longer tube down the 16" tube and bolted into place , once this was done added the paper mache which has now set (see pic)
Still got alot of work to do the paper mache needs smoothing then painting also need to add the handle,end tube and the trigger part but hey wouldn't be fun if it wasn't challenging
