    Cutting rifling

    I have a carbide rifling broach, it goes from 0.351 on the lands to 0.358 on the groves. I used dark cutting oil. Seems to work well. Cuts out to groves to about 0.356'' in 2 passes. Dark cutting oil seems to work well. Should I continue using the dark cutting oil or should I switch to...

    The coolant I used to use is no longer available and my stash has ran dry.

    Last year I poured the last of my conventional, non dex-cool, nonorganic acid additive comparable Texaco coolant in my tractor. I'm pretty sure I can't get it any more. So it's time to pick a new coolant. Looking for something that is non organic hybrid acid tech, a non "global" coolant. I...

    Any multi weight non-detergent oils available?

    I can't recall seeing any before. I left my jug SAE30 ND oil outside over night where the temperature dropped to about 0F. If you have never seen it before SAE30 oil is hilariously thick at that temperature, I couldn't even pour it out of the jug. I think a non-detergent 0w-20 or 0w-30 would...

    1999 dodge Dakota battery replacement (resolved)

    December 2023 winter is about to finally arrive for real in new Mexico. On the last nice day for a while I figured I should test my battery. Old battery is a group 27, rated for 650cca, made in 2020 but was also leaking acid around both terminals so I was kinda looking for an excuse to replace...

    What's the smallest filtering oil filter on the market?

    I know this is a bit of a moving target. I'm looking for the highest efficiency oil, the smallest particle size filter on the market that I can get in 11/16-16 thread. I'm going to add a bypass oil filter to my yanmar diesel generator. It didn't come with a filter but I have seen factory...

    Best place to buy pup

    I have looked everywhere in town and the only place that sells pup is advanced auto parts. For $41 a jug. Regular Pennzoil platinum is about $26 per jug at Walmart.

    In search of air compressor oil

    I bought 3 jugs, 2.5 gallons each of tractor supply "traveler" ND 20wt and ND 30wt oil. Got 2 jugs of 20wt an 1 of 30wt. They were on clearance for $3 each back around 2015. Those 3 were all they had or I would have bought more. I change the oil about every other year because it's so cheap...

    Doyle cast steel anvil from harbor freight

    I got one of these for Christmas https://www.harborfreight.com/65-lb-cast-steel-anvil-58924.html So far I only used it to drive some rivets and stretch some battery hold down bolts but it seems to work fine. Beating on rivets and a bolt didn't seem to dent the anvil surface. I would like a...

    Don't use pre-measured 2-cycle oil bottles unless you filled them...

    Had this happen to me before more than once, a bottle of red armor didn't have enough oil and made my weed eater stall. But the first time it happened it was my fault I accidentally used enough oil to make 2 gallons problem was I was using a 2.5 gallon tank, didn't realize it was a 2.5 gallon...

    Is 260F too hot for oil?

    I have a Honda gx390 powered 4gpm pressure washer. At maximum power it runs 4,000rpm, has about 30 degrees of ignition timing advance and runs wide open throttle. Seemed like it ran pretty hot. So I found a oil temperature gauge that goes in the dipstick hole to see how hot. I ran it on a nice...

    Which hydraulic filter is better?

    Filter is a 1 inch 12tpi thread head, max length I could go is about 12 inches long, but I don't know of anything over about 9 inches for 1-12 thread. About 30% price difference, but doesn't really matter as I'm only changing the filter every 2 to 8 years. System is powered by a gasoline engine...

    My new favourite thing: k&n air filter spray

    Good old K&N air filter spary, I wrote it off years ago and I was wrong. I'm putting that shuff on everything. I never bought into the k&n high flow rock catcher school of thought, they're probably fine for boats, maybe. Having can of spray on air filter oil that I can apply to foam...

    How to improve air filters that appear to be made out of used clothes dryer sheets?

    Hyundai/kia newer echo, toro, redmax stuff. The newer generation of air filters appear to be made out of used dryer sheets or felt like material. For vehicles and yard equipment it doesn't matter if someone else makes the filter they all made out of similar materials after market don't appear to...

    Running 40:1 in a 50:1 world.

    I have been running 40:1 now for a while with regular ethanol free pump gas and red armor oil. My echo saws smoke a little bit more if I let them idle for say 20 seconds or more then I get back on the throttle. Biggest change I noticed is the 60cc echo pops on the first pull most of the time...

    Hyundai kia oil filter cut open at 6,600 miles and 13 months on filter, 40,000 miles engine.

    Hyundai 1.8gdi hybrid engine recommend oil is 5w-20 and to change it at 7,500mi which is a fantasy. There appears to be a little dirt or sludge around the bottom of the filter. Since I use PP and 6,600 miles and 13 months is the longest oil change by far fo time and miles. Usually I'm doing...

    Just how fast does Pennzoil ultra platinum clean?

    1998 Pennzoil 5w-30 sj oil

    I found and used what I'm sure is the last jug of Pennzoil 5w-30 oil bought back in 1998 or 1999 on clearance from Wal-Mart. The oil had something that looked like wax or vanish almost looked like oil buggers. I tried taking a picture of it but you can't see it in the pictures. Used it in my...

    Need to replace the front wheel bearings on my Dodge Dakota 2wd. What are the best bearings to look for and what should I avoid? Working heavy industrial my favorite bearings are skf and fag, but they probably don't make automotive size bearings. Looks like I have to buy the hub assembly with...

    When to change hydraulic filter on log splitter? Possibly solved?

    I bought my log splitter about a year ago and ran the heck out of it. Split all the wood from 3 huge four and five foot diameter trees plus a whole pile of knotted wood I was saving for later. I was going to change the hydraulic filter this year since it was new. Then I salvaged some pressure...

    STP filter "2 oil changes" unknown miles cut open with sludge deposits!!

    Got a 1999 Dodge 5.2l Dakota. Changed the oil, at unknown miles. But I think the oil filter has 2 oil changes on it. I say that because it looks like someone used channel locks to attempt unscrewing the oil filter, gave up, ran the filter with the channel lock scratches long enough for them to...
