    Butyl rubbersealant cleanup recommendations?

    I am using C.R. LAURENCE 777BL CRL Black 777 Butyl Rubber to seal an aluminum window frame to the fiberglass siding of an RV. As i tighten the frame excess will ooze out which I need to clean. Looking at the tube it has no clean up instructions. I called the manufacturer and talked to a lady...

    Can anyone help me ID/source this seal type?

    Best I can find is it's an Tee seal but I know there has to be a more common (and easier query-able) trade name or term to try to source the size I need? This sits in the channels of my rv windows to prevent water intrusion.. The channel it sits inis about 5/16" and the top part is ~3/8" but I...

    Quick electrical wiring question, derating break for Level 2 charger

    I'm not going to run this as I cannot easily bend 1" EMT so i'll leave it to the pros. Anyway the run is less than 40'. I am having them run 4AWG THHN to a service disconnect. THHN is rated at 95A derated to 76A for continuous use. I am only running 3 current conductors and have no thermal...

    Who knows the thread pitch of a 5 qt synthetic jug ?

    I have a class A RV that has the oil fill in a nearly impossible place to get to. I have a funnel that will screw onto a standard quart synthetic bottle and or a coolant bottle but not what I need most, the 5 qt mobil 1 jug. I am going to 3D print an adapter as I cannot seem to find one so I...

    Grundfos comfort PM 10-16 auto adapt DHW recirc. pump question.

    This hot water recirc. pump has an internal and an external temp sensor for the auto adapt and temperature readings. I have a 1/2" return line from the furthest fixture that sends that hot water back to the tank via this pump. I plan to use the temperature control option because my usage...

    How to flood your basement in one simple step

    I've never seen such a failure in my life. I'm lucky I happened to wake up and hear not on only my sump going off but water gushing everywhere. Luckily I have a utility sump/basin that was catching SOME of the water and pumping it out. Hopefully I can get this fitting/adapter withiest having...

    Suggestions for a local company or chain that can mix a paint code (2 stage)

    I haven't bought any paint or supplies in 10 plus years and have since moved from where i used to get supplies but I want to buy a pint of an OEM paint code as well as the clear I will need and some clear blending solvent. Who do you guys use? I think NAPA does but I feel they'd be super...

    Amp clamp and DC current measurement on multiple conductors?

    I have a battery that I am measuring current to. It has 3 conductors. I assume I would have to total the sum of all 3 conductors to the + side of battery to measure total current correct? I also noticed that the sum of those is fairly close to putting the amp clamp around all 3. I have...

    Suspension guys step inside please.

    I had to put wifeys car on the lift to fix an oil cooler leak and noticed the inside of the FL tire was showing cords. We just got new tires put on late 2019 at firestone and had the alignment done since we have a lifetime alignment. She hasn't put many miles on the car and the tread on all...

    Anyone good w/ LiPo protection board PCBs? Need to ID a part

    This is for a 1S LiPo I am using for a project in the shed. First let me apologize for my schematic, I've never really drawn one and I know looking at it will trigger a good many of you. The component is a SOT-26 and the marking was y1ig. I didn't draw in all of those 6 other chips (Also not...

    How much efficiency is lost in a solar panel if you were to use a 2 stage clear?

    Basically I have some cheaper LED lights w/ solar charging tops that highly oxidize due to UV rays and I feel it has to inhibit charging. I have buffed the plastic and would like to put an automotive clear i have left over from a project some time ago over it to prevent UV degradation. Will...

    trying to source a lockset, cannot seem to find this form factory anywhere

    My neighbor has a lockset that the ID of the square recess in the handles that the square shaft goes though has worn to the point it flops around quite a bit. I have no easy way to build up the brass material inside of the handles to fix this so I need to replace them. The locksets have zero...

    Solar charging lithium batteries, EEs have a sec?

    I had a ton of spare 18650s, spare LEDs, a 3D printer, a passion for designing stuff and some time on my hands. I have a solar panel that puts out 5V/500mA that I am charging a 3S2P config. I went with a boost convertor that uses an XL6009. I am using two BMS' that do 3S balancing. They...

    Anyone use an M18 milwaukee string trimmer. Have line jamming issues in mechanism?

    It seems to jam and bind in the mechanism itself. Perhaps I am putting too much in? I have tried a few different types of string (perfectly round, serrated, etc.) and they all do it. I am using the correct OD string and I believe it's actually from Milwaukee since I was having so many issues...

    Well THAT'S not good.. Ever see an AGM battery self destruct?

    I've never seen anything like this. It's for a lawn mower. The battery is less than 2 years old, never sits in cold and sits on an AGM compatible trickle charger on a wooden bench in the cold months. When i put it in a month ago it was NOT like this. Very strange.

    12Vdc guys, have a wiring diagram question for you (Turn signal stalk)

    I've included a turn signal stalk wiring diagram for a mid 90s ford F53 series RV. I'm focusing on the turn signals. When the left signal is activated 12V is fed along the LT GRN/WHT wire via the flasher. What confuses me here is you can see the hot feed for both the L and R (WHT/LT BLU) are...

    Ryobi 3100 psi pressure washer, cannot get the high pressure hose orings not to leak to save my life

    I swapped new o rings in, inspected the bores the orings ride in and even swapped the hoses side to side and no matter what I do I get a leak. I'm out of ideas. I initially figured that since the orings didn't resolve it it had to be the ID but the ID is smooth. One side is a copper fitting...

    Need opinions on reattaching a pressed in thermactor air tube

    This is in an RV w/ a 460 ford. The Thermactor air tube appears to be pressed into a flange which bolts directly to the exhaust manifold. The bolts for the flange are very hard to get at w/ little abilityto get any leverage on them. I fear they will break if I could even get the leverage...
