Did you ever end up welding PP without a shielding gas? I've been told the same thing recently (that you need shielding gas), but could've sworn I've done it before. I know I've done a ton of ABS which is easy, some PVC which was less easy. Maybe I'm remembering wrong and I did HDPE, but I'd...

I haven't seen anything affordable that works OK. I usually get my exhaust pipe from a local exhaust shop, and it's a decent wall thickness. Maybe that's my problem? Perhaps cheap Chinese pipe from the parts store would stretch easier? I've broken them too. I dip them in oil before use. It...

I did some more digging. It looks like the Sikaflex 1C SL is a polyurethane base. They list a Shore A hardness of 45 +/- 5 tested to ASTM D2240 standards. The Rapid Set silane polyether is tested to a Shore A hardness of 15, tested to ASTM C661 standards. From what I can tell, C661 just has...

Anyone want to keep talking about filling their cracks? I have hand-troweled control joints in my slab, so they're more generously sized than saw-cut. I filled a couple of them with sand leaving 1/2" in depth for some of the Rapidset self leveling hybrid silane polyether. It self leveled...

With prices climbing, even Supertech has been $3+ in the PNW. I went to Autozone and bought a 5 gallon bucket of their brake cleaner (acetone/heptane/methanol/toulene) for $81 after 10% veteran's discount. I haven't used it yet. Just got my Sure Shot from Amazon today, and filled it with dead...

Does anyone happen to know what type of plastic is used for these? I have a V20 drill I need to attempt repairing for a friend. I've tried searching for general power tool materials, but it seems there's a lot of variety. I would assume ABS since that's cheaper than some of the nylon mixes, but...

I got a sample. Framing nailer works just fine, if anyone was wondering. I'm still a little torn, but leaning toward giving them a try.

I'm not sure if they have anything similar. Mostly what I see there is SIPs with a skin on both sides rather than one.

Thanks for the info, that was really helpful. I'll be in the same town as the seller tomorrow, so I'll buy one or two to play around with. I think I'd like the exposed aggregate look and the durability/flame resistance. Fastening may indeed be the big issue. I was imagining a consistency like...

I found them for sale locally, and they may help me out. I've been searching, and looking at SIPS panels, and haven't found anything like it with the thicker concrete layer on one side like this. They were described as being used for constructing green buildings. They're supposedly 2'x4'x2"...

Ever rewound your slinky the wrong way? I wouldn't be surprised if these springs are wound on the same machine, and then one of them is "reversed". Why have twice the tooling? Manufacturers have all kinds of tricks to save a buck. As mentioned before, the axial tension on a torsion spring...

Sorry the city was no help. Those ARE indeed stick built rafters, not trusses. As mentioned, the face-nailing isn't ideal. It puts all your nails in single-shear loading. I hope you don't have much snow load. With they way they're built, those rafters just aren't a good candidate for...

Anyone ever heat up their crack sticks with a flame? :lol: https://www.homedepot.com/p/Crack-Stix-125-ft-Medium-Gray-Permanent-Concrete-Joint-and-Crack-Filler-2051/203658275#product-overview

Honestly, it's a huge blessing that it happened on the lift, assuming no one got squashed. Better there than 60 mph somewhere on the road!

I feel your pain. We just bought a house next to a river in a Cascade Foothills rainforest. This location gets about 80 inches a year, and the river is about 200 feet away. The sun is too low in the sky in the winter to ever make it over the ridge or through the trees (assuming the sun is even...
