What sort of performance are you getting out of your vacuum set ups?
My first go doesnt seem quite there.
If I run it to 8", the pump switches on every 40 seconds, but only for about 3 seconds. Does that sound right?
The vacuum pump set up by itself will hold whatever setting for a long time, so I think it’s the bag, which is just plastic sheet taped together. I can’t hear any leaks.
I fought with the sheet plastic/tape method too. I wasted alot of time and hair trying to get a decent seal. I finally ordered some bagging tube-4mil-from fiberglass supply. The stuff is cheap and works very well. I have bagged four boards with the same bag and so far no drama.
I also made some bag seals similar to the ones that acp sells. I used a 3/4 poplar dowel and some thin pvc pipe. I cut the pipe lenght wise on the band saw and deburred the edges, snap togther at the bag ends and walla…
1.None or too small vacuum resevior.2. Check system prior to bag hook up. Holds vacuum? If yes then it is your bag. If no find the leak in the system and try again.
I used 4 mil from Home Depot and cheap masking tape (a lot- maybe one whole 2" roll). My pump was rated for continuous duty with a bleeder valve. Worked like a charm. Maybe I had beginner’s luck?
