Another post, this time a partial about my chamber build. It's going to be a 4" schedule 40 PVC tubular pipe with a cap on one end and a fitting that has the threaded female cap on it. My plan was to cut a 2" wide piece, then super glue it on a 4 1/2" square. That worked out great as after cutting it in half at 2 3/16" x 4 1/2" pieces. My next step would be to heat each piece only across the highest point, then apply downward pressure with the pipe to get the legs to conform to the OD of the pipe. HUGE failure as the whole piece heated heated to where it looked like a thick slice of bologna in my hand. It was still hot and I did everything I could think of to get to to look good, but the first leg won the battle.
I went to the second one, and heated it a little differently, but still had bologna issues. I got it looking better than the first one and decided I was going to use both, so get my sander ready to sand the PVC before applying the primes. No go with the small Ryobi as the plug was missing one of the blades on the plug. So grabbed one of my trustworthy Rockwell 505's, and did the sanding.
Got both legs attached with the glue, and will be 3-4 hours before I pick it up and install the 2 end caps. Then it's attaching the air supply. I haven't really decided where I want the connector to go. I also must figure out how to attach a diffuser so the air doesn't blast out the resin in the boxes when I'm pressurizing the chamber.

This shows the leg. I'm only going to use the cut on the right for the two legs, and the piece on the left was going to be used to bend the legs to conform to the body of the chamber.

This shows the legs after being heated and bent. Pretty bad job on my part.

I set the legs up on it to mark the area for sanding.

Got the chamber and legs primed and glued. I used a couple lead castings, about 15 pounds each inside the chamber that I normally use to hold down my tarp on the saw. I positioned them just above the legs to get the pressure I need.



I almost had a problem with my cursor, but as you can see, it worked today. More posts coming as I progress.
Later today I might get the ends secured. Not sure about that just yet. I might wait 24 hours before I mess with anything more. ................. Nubs

I didn't mention the disgusting look of my saw table. I blame it on the weather report that stated no rain for the next 10 days. About 15 minutes later, we had a pretty good sprinkle. ................ Nubs

Today I completed the pressure chamber build. Got the regulator, gauge and shutoff valve installed.

This is a 1/2-14 NPS tap for the bushing I'm using for reducing from 1/2 to 1/4" fittings for getting air pressure inside the chamber. It tapped easier than I though and was a whole lot cleaner than I expected. When I screwed it on, I expected that to be the location of air leaks if I was gonna have any. Nope, not there.




Here is my set up. Valve, pressure gauge and regulator.


This picture is a pair of legs in the box full of resin ready to be sealed and put under pressure.




Well, I put it under pressure and noticed a small leak coming from the threads of the chamber closure at about the 3 o'clock position, but it was a small leak. I don't think the compressor came on more than once in 3 hours to top off the line pressure.



After 3 plus hours, I released the pressure, opened the chamber, and was pretty disappointed at what I saw. The resin was still tacky, and most of the resin was gone. Fortunately, it did not leak out of the box. It found all kinds of places to fill that I suppose I didn't know were there. Anyway, I set the box of legs on a table in the sun and let it sit for another couple hours. It set up like it's supposed to. When I mixed the resin, I did approximately 21 ounces. & hardener, and 14 ounces of resin. I should have waited at least 5 more minutes before sealing the chamber in order to see if there was plenty of resin used. The container to the left has about 8-9 ounces left in it and I used it in the other box of legs, but when moving away from the area, my tape measure caught the second box and pulled it off the table. I lost most of the resin, but it didn't hurt the box of loosen the legs.



This picture shows the absence of resin, even though I filled the box to the rim. Anyway, tomorrow will get that pair of legs done, and will cast the second pair, then cast to apron parts. The resin is being used only to solidify all the wood because there are a lot of cracks that I want to fill. I don't think they would be a problem using putty, but I'm gonna use resin.
I had no problems inserting pictures until this last one. ............. Nubs

Cool setup. I've been following along and thinking how I'd do it if ever necessary. Wouldn't have thought PVC took threads that well that they wouldn't leak. My thought was drilling through one of the caps, using a NPT to SAE thread adapter and using rubber washers on both sides to seal. Your method is much cleaner of an install. Curious how much pressure you used?
