What did YOU do today?

FYI, not for steel, but for aluminum, use wd-40 or equivelant.

By about 7 it was a balmy 95 so I jumped on the tractor and started mowing the reed canary grass... was actually much cooler where it was so it wasn't bad with a drink and cigar... just got back in from that, annoying that it is dark by 8:30 already... the cheap LED lights I put on the tractor make radio interference on my 3M work tunes which is annoying...

Might head back to the shop after dinner and put epoxy of some form on the mini sledge from last weekend and do some tuning on one of my come-alongs...

So… I will say that o do really like Tap Magic for cutting threads… I just use regular oil for drilling though. I had some spray cans of some drilling stuff but apparently they are gone now because I can’t find any. Tap Magic gets pricy for drilling fluid.

I’ll also say that, @Blmpkn , check what speed it runs at. My benchtop HF drill press, the slowest speed is still waaayyy too fast for steel. It will drill, but it’s too fast. I’m considering ways to resolve that…

Any idea what the optimal RPM is for cutting steel? With a hole saw? Idk if it makes a difference hole saw/drill bit but I imagine it does..

Either way, it's actually pretty slow when it's set to its slowest speed.. like... mabey right around what an old 12v cordless drill would do wide open.. perhaps even a little slower. All I know is it's way slower than an 18v drill lol.

I'll have to see how fast the motor says it spins and then measure the pulleys and do some maths tomorrow.

So Ranger Sunday was.. dare I say.. an extreme success today

I didn't get to actually FINISH what I started.. but I'm DAMN CLOSE!

So incredibly happy to be as close as I am to being DONE with chassis repair ( for this year anyways)

Details in my build thread

So for twist drill bits:
1/16-3/16” bits - 3,000
1/4-3/8” bits - 1,000
7/16-5/8” - 600
11/16-1” - 350

Countersinks I saw anywhere from 50-560 rpm and there seemed to be a bit of disagreement over where it needed to be. I haven’t gotten around to pulling out my machinists books to see what they have to say.

These two showed up at my pull yard a few days ago and I can't get off the couch to go scavenge. An 87 and a 94 my year and XLT trim
There's also a black 93 xlt ppffpffpfphhhtht

More tractor work today, took the hydraulic pump all the way apart & cleaned everything, wire wheeled the hood pieces & patched the bad spot on the left side of the hood. Painted underside of hood and hood doglegs with eastwood encapsulator. Put the painted back fenders in the box trailer to get them out of the way & in a safe place.

You’re welcome.

This is super awesome, thank you.

Looks like a 2.5" hole saw wants a measely 130rpm for mild steel.

I'm betting my press is like yours then.. probably way too fast even running its slowest setting..

I'll have to get to math'n tomorrow.

I’m far from an expert, but I do remember from back in the day, that the oil/coolant is a huge part. If you can keep the bit and the steel cool, you can cut it faster, but the second you get it hot, you’ll ruin the whole saw and then you’re trying to burn the steel out.

I have a Sears home model drill press from my uncle from about 1950. It’s damn near as big as a commercial press. I’ve been wanting to put some kind of pan underneath it, with the little circulating pump so I could just keep cool stuff like that soaked and cool the whole time I’m doing it. I know it’s going to happen, I’ll get that done in a year or two after I actually accomplish everything else I want to do with the drill press! Ain’t that just the way it goes?

On your cutting fluid, if you cut your oil with some solvent, the solvent will do a much better job of keeping it cool. You just have to be careful you’ll burn your shop down when you’re doing it.

Good luck with it

The way I've heard to get the best cutting and life from the bit is to figure out the feet per minute at the cutting edge, then adjust your rpm to that. I don't have that info but I'm sure if you goggle it that there will be charts for all the different metals and types of bits.

Changed the bolt on the axle of one of my good come alongs since it was bent bad... then went floating the river on an innertube which was good. Did end up finding a couple agates. Don't have much more in me tonight...

Reserved some tickets for the re-imagining of The Toxic Avenger next Saturday.

Not a single theater within 2 hours from my house wants to show it apparently gotta drive out to some little bum-f lake town in NH to catch it. Oh well.

Productive day here - All that's left now is headers, plugs and wires, carb, radiator, grille and hood. Had to fight with the alternator bracket to get the belt aligned properly but we finally figured it out. NHRA Canadian Open starts Thursday so it looks like we'll be ready for it.

Looks like the alternator bracket is to the frame? So the engine is solid mounted? And the water pump is run off 12V electric?
Good luck!

Installed the super pro 6th gen ranger rear sway bar. This thing comes with nicely made brackets and really nice hardware. The end links are very cool, too
