    What are some of the tools manufacturers could make, but don't make?

    Milwaukee would make a rear handle cordless 8 1/4 circular saw. Axe manufactures make diy kits. A head, handle wedges and file all in a kit. Would be a great gift. All they would have to do is slightly rebrand the component they already sell. So if the user poorly fits the peices together it...

    Old school residential HVAC tools

    Anyone else remember open drive vacuum pumps? Used an analog scale at one point. Charging cylinder to weight in very small quantities of refrigerant. Don’t forget the Simpson 260 MM. With the leather case

    My father’s on his 5th Snapon auto body hammer handle under warranty. He’s gotten more $$$ in replacement handles than the tool cost new.

    Speed Handles --- What They Good For?

    I’ve got at least 4 of them. All were free. Which should tell you something about they’re perceived usefulness today. My two 3/8. A Koken and a proto. It’s amazing how similar the two tools are. Yet how much more usable the proto is. The specs on paper and the real world ergonomics are two very...

    Snap-on 1/2" Drive x 36" SN36 Breaker Bar?

    I’ve got the 24” Snapon version. For the work I do it is typically sufficient. When the 24” gets flexy I move up to 3/4” drive.

    What material for filter box

    You are going to find that the inherent problem you are trying to solve. Is that your pressurization medium is contaminated. Also you will need a post charcoal pleated filter to catch the dust that comes off it.

    What material for filter box

    I’ve used these to pressurize spaces. They work well for pressurization. But with pressurization comes wild thermodynamic changes. No idea on the cost of one of these. Where I’ve installed them budgets are a suggestion. https://www.cleanairfilter.com/products/filtration-protection-systems

    Saw a 7mm wrench for sale. Where would you use one?

    A off brand Chinese air conditioner I recently installed has hex head/phillips screws on it. The hex was 7mm. The thing was werid. Like the indoor unit had service valves. But not a pre charged coil or line sets. Danfoss pressure controls use a 6mm hex/ Phillips for the adjustment.

    Radiant in floor heat system help

    For the pump. It really depends on the model of boiler you go with. A low loss header could be installed to decouple the flow rates between the boiler and the slab. This would require two pumps Boiler sizing is a tricky one. As the efficiency generally starts at 80% and goes up over the length...

    Radiant in floor heat system help

    Talk to your local viessman rep. I used to install them in bc. Parts and manufacture support was great on the west coast. Nice units. Timers or not. Your hwt is only 6000w. That’s not enough energy to heat your space all year round. It may barely keep up above 0*c. Then there’s insurance...

    Angle Grinder PPE

    You’re looking for a ppe solution to a tool selection issue. Yes for decades an angle grinder and zip cut was the tool for cutting metal. But carbide blades have advanced so much. A metal cutting circular saw is a much better tool for cutting stock. The blade guarding is so much better on a...

    Awesome tools you have but never use

    I hate Allen wrenches. Despise them. Couldn’t design a tool that values cheapness over usability. Bought an entire set of fractions sizes. .50 to 3/8 Snapon hard handles found them on eBay after weeks of looking. Used the 1/8 a couple of times. The 5/16 once. But generally don’t have use for...

    Flex Head Ratchets - Which type do you prefer and why?

    I have generally switched to flex heads. A big reason for this is how much better they fit in my pocket with extension and socket. Locking dual 80 1/4 is my favourite If I ever need another 1/4” or 3/8” drive ratchet it be this or its successor. Not sure how this could be meaningfully improved...

    Rotary Hammer Drill with Core bit

    Depending on how many several is and the finished tolerances. Using a small SDS drill with a 3/8l bit following a drawn circle can get the penetrations done. Generally this leaves a rougher finish than the core bits.

    Has anyone EVER used a 16mm or 18mm wrench/socket?

    Used 18 or a cat or Deere loader. Can’t recall the brand. But it was well thought out. All welded on threaded inserts on the plates, no through bolting. 16mm/ 5/8. Used on flare fittings. Edit. I bought the 5/8” socket for my 1/4” drive set. Only to learn that 1/4 sets do not come with 5/8...

    HVAC Improvements over the years?

    The industrial plant I work at makes its own power. Efficiency isn’t our concern heating or cooling wise. In some places we run compressors 24/7/365 and cycle on heaters to temper the air to maintain setpoint. How many of you would choose a new efficient unit over a nos 15 year old design...

    who trains these service techs? wild diagnostics here

    That’s true. But the business side the technician job gets in the way of this. Let’s say he puts gauges on. It’s low on charge or has a plugged metering device. The practical solution is the same, change the unit. A lot of small units calls are basically informing the customer to buy a...

    Let's Talk Flare Nut Wrenches!

    I have both the Snapon and Williams USA. They are made from the same forging. The Williams have rougher forged chrome finish. The snapon is the typical high chrome finish. I find 6 point crowfoot sockets a good companion to the wrenches. The two plane offset on the wrenches can be challenging...
