If I stick with it I think I could put it togeather in about 8 hrs. But I spend a lot of time scoring glue spots and smoothing off the mold joints etc. so you may want to add an hour or so. It also depends on how good you are at putting in your radio gear etc..
By the way here's another hint: When smoothing off the mold joints I scrape them with a hobby knife then use a " Drywall Sanding pad " to smooth it out. I like them better then fine sand paper, they come in different grits. You can get them at most hardwares or Home Depot.
Another hint: I have had real good luck reforming some spots if I need too by using a heat gun. You have to be real carefull about how much heat you use and you will also want to wear gloves if you try it. On my Beavers ( with 46's ) I had to do a little reforming of the cowl to allow a little more air to the carb. JUST BE CAREFULL of your heat.
ENJOY !!! RED
