No hole saw for SAB, no problem. Heat gun tek.

Just came up with a cool idea that worked well and thought I would share as I didn't see any old posts referring to heat guns. I know people have done blow dryers and coffee cans, but I didn't have a coffee can that fit my desired hole exactly and a heat gun is about 1000x faster anyway.
I am following Frank's 12 step program and constructed by SAB tonight. I didn't want to spend $25 on a hole saw for the arm holes, and while I was looking around my garage for what I could use instead I found my heat gun (actually cheaper than a 4" hole saw) and came up with a plan. I realize this will only apply to a select few who own a heatgun, but alternative techniques are always fun, right?
Step 1: Set up a work area outside or in your garage with the door open, we will be melting plastic here. Lay your tote down so the side you want the armholes to be on is facing up. Use a sharpie to trace around the skinny and fat side of your PVC cleanout adapters in concentric circles.
Step 2: Find a partner, a heat gun, and a knife. I used a shitty utility knife, something sharper or stronger would have made this even easier.
Step 3: Put some newspaper down on the bottom of the tub to catch the hot plastic if looks are important to you. Turn the heat gun to high (1000 degrees F on mine) and spend about 30 seconds going all around the inner circle to soften the plastic up.
Step 4: Put the heat gun within an inch or two of your tub, with the edge of the gun on the inner circle. The middle of your gun should be towards the middle of the tote to avoid melting away more of the plastic than you need to.
Step 5: Have your partner follow your heat gun around with the knife. Go as slowly as you need to for your partner to stay an inch or two behind you and have the knife slide in very easily and almost literally be like a hot knife going through butter. I thought about flaming the knife, but it turned out to be very unnecessary.
Step 6: Immediately insert cleanout into each hole as you cut away the plastic, twisting as you insert. Let dry.
This took about five minutes total, and another 20 minutes later the plastic was completely dried, making a solid seal around my ports. I'm adding a layer of silicone to the inside and outside as well to completely block airflow and provide a stronger seal, but it looks pretty airtight as is. I was able to lift by the ports with no slippage. If you work quickly, you can cut a little inside of the inner circle, the plastic will be soft enough that you can still force the cleanout through. There is also no risk of cracking your tote with this method.
If you don't have a partner it's definitely possible to do by yourself, I did the first hole myself before thinking of having my wife help. Having an extra set of hands lets one person operate the gun and hold the tote still (can be accomplished by putting weights on the bottom of tub) while the other operates the knife and is free to move around. Makes things much easier. I tried just using the heatgun to melt the plastic. It was working, but was going to be hard to get it to stop exactly on my inner circle.
Sorry if this has been covered before, but like I said, I didn't see anything like it after doing a quick search. Happy growing all!

Haha sounds legit! Muda does a soldering iron. For me I like to take a blow torch to some 1" or so impact sockets, and press it on the places I want holes at.
Spade bits for drills are fuckin legit too. They cost like $2 around here lol.

I like it...somewhat complicated, but I bet the seal is legit af, even before silicone.

If they make 4" spade bits, I haven't seen them 
Soldering iron is a good idea, I have one of them and didn't even consider it. Love the ingenuity this board shows though. There are a hundred solutions for every potential problem!

Oh wait sab not monotubs LOL. Yeah I just straight coffee can that shit lol
Check out the improve your sterile techniques link in my SIG. It has a 2 minute video on making the sab

That's a good vid, I like the offset arm holes for pouring, but I haven't gotten into agar yet. My plan is to do that after I have success with monotubs. I've grown with PF Tek Done Right several times and done fine, but with small yields. Hoping Frank's 12 steps will help me out there. I'm excited to get into cloning and want to eventually work on genetics and have some shrooms I can really be proud of, but for now I just want to get my technique down for high yields 
The link in your sig is great for demonstrating agar transfers by the way, everyone talks about them a lot but I haven't seen many pictures of it. Why do you recommend 6" holes for your SAB? Frank's thread said 4-6" holes and I found 4.5" PVC cleanout adapters, tested to make sure my arms would fit easily and figured I would be good to go and that smaller holes would mean less airflow.

I thought I explained it well haha. Basically as you put your arms in and out, and just move around in general, the arm holes will equalise pressure if they're small and restricted.. Creating an air flow of contams near the arm holes. And the contam spores just fly around so easily..
You're pulling your arms out every transfer or inoc because you need to flame the tool outside the box. Don't flame in the box.
As long as the air outside the box is still, you putting your arms into less restricted arm holes is much better for air pressure. Make sense? It really helps if you don't bump the box at all as you enter it too lol

I'm a dummy, you explained very well. I was reading quickly while watching TV and thinking about my own grow and just missed it. Since you don't have cleanout adapters, you also don't have tyvek sleeves though, I would think that with them, the size of the hole would be irrelevant, as your arms are still just going through the sleeves and their size wouldn't change at all. I will borrow the idea of lighting an incense to test air movement though.
Since I have a willing partner, my plan is to only remove the arm with the needle, have my wife flame sterilize and rewipe my glove with alcohol, then reinsert into SAB. Having a second person in the room seems risky, but I think it's worth it to only have to remove one hand instead of both.
Frank also doesn't mention sterilizing between each injection for MS, but most other people say it's a necessity so I assume he just left it out because it is common knowledge. In my very inexperienced view, it seems like I'm more likely to force contaminants into the SAB by removing and reinserting my arm between each inoculation than I am to get a contaminant from one PCed jar and transfer it to another by not sterilizing the needle. I will defer to the experts though, and also know not to sterilize inside of a contained box with a lot of alcohol in it

It's that and its also because flame moves air around A LOT. Not only does the heat make an air current, but it requires clean air to burn as well. You really have to think of the ways to make the air completely still. Once that is achieved the only thing you have to worry about is your hands or arms accidentally going over shit. Think of them as just constantly raining bacteria lol
Also I don't use sleeves haha. I don't even wear anything. Just naked arms.
You've got a nice girl if she's actually willing to do that for you.. My girl couldn't stick around long enough to even watch a transfer. She just took the dish and wanted to poke the myc lol
