I just picked up a new 3/8 drill bit to go with the 1/4-20 rivnuts.

It's a winner. First try and it came out great. Super tight.
The rivet threads are a little sloppy, but locking the eye in place with the nut will do the trick.
Nice clean look when its done too. I'll bet you could bolt two tubes together with these. Maybe use a little blue or red thread lock.
Wish I had this when I was doing the ridge vent.

Its easy to do.
The drill bit has to be just big enough for the rivet to fit in the hole.
Drill the hole in the tube and screw a new rivet on to the puller with the arms all the way open.
Put the rivnut in the hole and close the arms.
The puller plus the rivnut so it crimps on the backside (inside) of the tube.
Unscrew the puller from the rivnut with the nob between the arms.
Done. It takes more time to drill the hole than pulling the rivnut.

I got the 37 buck puller for two reasons.
It was 12 bucks cheaper.
The replacement mandrels are easy to identify because they come in color coded boxes.
I got a spare 1/4" mandrel.

This one.

I like it. In putting it on my list of shit to get.

Get yourself a spring loaded center punch off Amazon for like 8$. and a few good cobalt bits.

Mark your spot with the punch so the bit doesn't walk when you are trying to drill. Drill a pilot hole with a tiny bit. Then go through it again with whatever size u want the hole to be.

Your holes will be perfect and they will be FAST.

So.. I'm using a swamp cooler in a veg greenhouse to dry my weed. Because it is so dry and hot here, it's able to keep 50%rh and 70f.
The swamp cooler was an old POS that was sitting at my neighbors for years. I just used the frame and replaced everything else internal. Pads, pump, float, water distribution tubing.
I put some pvc hoops over the greenhouse so there is an air gap between the layers of plastic. Way better insulation

No need to automate it.. I only black it out once a year. It will stay blacked out until my veg for next year starts around jan or feb

I figured i would share these heaters with you. They run of diesel or kerosene. They are VENTED. Super cheap. About 120$ a heater. For small greenhouses they are great. The one in the picture is just ghetto rigged temporally so i can dry weed in this greenhouse. It's set up to bring in cold moist outside air and heat it instead of recirculating. Normaly i would just have it recirculating. It has an intake and exhaust pipe at the bottom like any other furnace. They are meant to heat RVs and stuff. I know people using them to heat cabins and small houses.
They are dc 12v or 24v. Extremely efficient. Can easily be run off a small solar panel and 12v battery. The blower in it is great. Not sure on cfm but for the energy it uses its amazing. Only 3" duct but it seems to move as much air as a 4" inline. Can push through some pretty long duct runs without any loss.
Extremely efficient on diesel.
I think they put out about 20,000btu.

Thanks

Thank you for this thread
At this part of the world, a beautiful steel hoop greenhouse of about the same size of the first post would cost 3500u$s and this is luxury only large vegetable producers can afford
Here the only kind of plants that will grow well are sativas, and the only way to finnish them here is light dep.

A greenhouse for home using the cheapest material around here is eucaliptus wood and this is the kind of construction which is common at this part of the world and by far, the cheapest available, bases have been fixed with concrete so it will be strong to stand against tough winds


The materials used for 3 walls is transparent nylon 150 microns, white shadow mesh for the roof and for this wall a triple folded shadow mesh. The white shadow mesh allows ventilation and allows me to make rain inside to cool the greenhouse when too hot. It is very windy here, it is an area of eolic energy generators so I feel to have enough ventilation just with the mesh in the roof

This is the triple folded shadow mesh wall, on top the wire to hang the light dep nylon


I am really interested in light dep
Nobody ever heard of light dep here, people think I am crazy and maybe they are right
Master CrushnYuba, I think I am using the same nylon I see on your last post. The one I am using is 150 micron and I use it as curtain which I pull up and down with a simple rope and a sheave
What I have seen in videos and pictures seems to be very heavy, like 30-50 kilos to pull on the light dep nylon cover
To pull up and down a wall of the nylon is very light and simple to do, I thought I would have to divide the light dep wall curtain in 2 so it would be lighter, but I am surprised it is so light

I am discovering I have a very wide thermal amplitude. It goes at this time of the year 13-15C at dawn with 99% humidity up to 35C and about 45-40% humidity on the same day.

Thank you very much and have a nice day

This is the wire for the curtain, from the sides I wont be able to completely bring up but I still have plenty of light and is not noted


And today we just made the first side wall curtain and we finnish the next two days I think, hopefully tomorrow
