Hello AzViper,
First I just want to thank you for sharing your awesome design! I have been interested in getting a gas powered vac for some time, but I haven't been impressed with what I've seen available commercially, and the prices... forget it!
So I am in the process of collecting the parts to build my own. I purchased an Echo PB251 off of Craigslist in brand new condition (only used one time for 30 minutes!) with two sets of spare parts for $100. And I ordered a bucket and lid from the link you provided. I have several questions I would like to ask you.
1) The bucket lid does not come with a gasket. Where did you get your gasket? Or did you make it?
2) I cannot find a 2-1/2" PVC elbow at my local Lowes or Home Depot. Where did you get yours?
3) Why don't you just glue the elbow to the 1/2 of the 2" coupler?
4) What is the part shown in these two pictures?
Thanks again for sharing this awesome build! Next I'm going to check out your other projects - in particular, the blue bowl. Although I'd
love to have a trommel...
Ron
