POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

[Eyerelief]

John. I really like both of mine. I bought the smaller version with the 7.25 blade by Evolution and the large one is a Milwaukee . No carbide dust but a ****on of tine blu chips. I cut 30 pieces of oil field drill pipe with just over one blade with the little portable one.

That's pretty impressive, that's handheld, right? I'd expect the handheld blade to have a much shorter life with carbide teeth. I am actually unsure if the teeth are carbide, they have a silver color to them, they could be a tool steel. The blades are Japanese, for what it's worth.

I love routine, so Jack & I do pretty much the exact thing every Sunday (which is my only day in the shop).

He arrives on his bike at 8:00 AM & gets right on the knee mill making plate coupons. I makes us espressos that we drink together while he is executing a power feed of 3-12 ipm. Then I *sit* at a fixture stand (inside or out depending on the weather) just welding coupons. We listen to 80s-00s rock (e.g. AC/DC).

Right at noon, I take him out to lunch which is the only time during the week that I cheat on my diet. It is almost always Mexican food.

Lunch is about 50 minutes, & the afternoon is a repeat of the morning, but the last 30 minutes is cleanup. After exactly 8 hours paid, he rides away on his bike.

Same thing every week, but the next project is pipe coupons so he will learn to use the engine lathe.

Jack setting up an .045” (roughing) DOC 35° bevel cut in 5/8” mild steel plate with a 7/8” solid carbide endmill in an EMH. Feed rate is 11 ipm. Spindle RPM is 1200:



I am doing a SMAW horizontal edge weld on .125” mild steel sheet. 3/32” 6010, 70A on the 220V welder:





Stick welding is my very favorite thing to do in the whole world. After I weld up the plate & pipe coupons that Jack makes, he will torch cut & recycle them by machining them back to exactly how they were before!

No John it’s the mini me to yours.


It’s 10 amps. I like it because blades are around $25 bucks. And yes I believe they are carbide.

@Eyerelief
If I got the math right, that's about $1 per cut in blade wear. I don't know the dimensions or mechanical properties of specific material you cut, but at a dollar a cut, Yipes.
I'd appreciate more info about the drill pipe material, hoping to make the $1 per cut more palatable.
Do you intend to resharpen the blades or ???

I believe this pipe was x95 drill pipe 2-3/8” diameter .280 wall. Believe me it’s a bargain. The pipe is tough. To get that all cut for $30 was well worth it. The blades aren’t salvageable at least when I’m through with them they are not. They cut fantastic all the way up to catastrophic failure. Nothing left to resharpen. The 14” saw turns with less RPM and I have successful had a couple of those resharpened. The finish with a cold saw and a sharp blade is really good.

Thanks for the details.
It looks like X95 is minimum yield strength of 95,000 psi.

Rain day here so found a shop project. Have had this stereo microscope head for so long I can't remember where I acquired it. Guessing 10-20 power. Made the arms to hang it off the small lathe when I have to pick up a thread or find a shoulder. Mounts where the collet closer that I don't have would go. A quick powder coat then had to raise the tool rack 3 inches to let it fold out of the way,

Today, I finally got around to unboxing my Evolution toothy saw... I've been kinda on target lock with my Nardini, so no welding or chop sawing the last couple months.

Here it is next to the abrasive chop saw it's replacing. I won't get rid of ol' smoky, I don't think a tooth saw can completely replace an abrasive saw. I've just run this one hard on paying jobs and everything else for years and the bearings are shot, the brushes need replacing, and the armature needs to be turned. It is a USA made saw, after all, it just lived its life in abrasive dust and grit. Anyway, I'm pretty excited to put this new saw to work.

Just used mine today. Made two cuts, 4" x 1/2" A36 plate. I would say both cuts were under 4 minutes each.

That microscope head would drive me nuts, really seeing how bad my cuts were ......... :~(
Nice job on the arm, though :~)
