Hello all,

I have an 8’ piece of 1.75” square 1/8” wall square tubing that i need to shave .3mm off each side so it will slide into a 2” square tube....

My idea is to get a blade for my table saw and make a jig to hold the pipe down. Then feed it throw slowly while spraying lube on the blade...

Is the right idea... or is there a better way?

I have cut some large pieces of aluminum on a table saw with a carbide blade. It worked fine and sliced thru relatively quickly. It did not require coolant/lube.

Trying to cut less than curf width might be the chalange. The blade will probably deflect making the surface choppy.

Might be worth contacting a local machine shop to see if they will mill it for you.

A variable speed plunge router will work as well.

It all depends on the tolerances you will accept. This sounds like a simple job for a milling machine. You will get a perfect job.

I am sure you could rig a grinder, but tolerance would vary. Routers are for wood. I have cross-cut aluminum with carbide tip saw blades, but I have never ripped aluminum.

Depends on the tolerances you need, I would use a sander. Any carbide or metal blades are going to gall something fierce.

I have cut large aluminum plate up to an inch and a quarter thick with a carbide blade on a table saw, you have to take your time and give the blade teeth time to clear the cuttings. Done slowly, it cuts as clean as cutting wood. If you make a jig that will hold your tubing securely, I don't think you will have any trouble doing what you want to do. Just go slow, so the blade isn't forced to deflect and it should cut even a thin slice and stay straight.

Be sure to wear safety glasses, aluminum chips in the eye will hurt a lot more than wood chips.

I always use a full face mask and ear protection. Those pesky aluminum chips seem to go every where, and they hurt. I wear a full face mask with ear protection and glasses.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Sorry to say that not any more than a tablesaw...but

...not too loud, please. All the CNC router owners might hear you and ruin their day.

I have used my VS router to mill ALU mounted to a table with a Jessem lift and a JoinTech fence for "precision". Unfortunately mine is MHC and not CNC. Plus the bits are cheaper than a blade.

Yes, even better. A sanding drum mounted to a variable speed drill press with a fence is much safer than power tools and even cheaper than blade or bits.

.3mm, I could even sand that much by hand in a few hours or less.

Always make friends with people that have tools. You should mentally catalog their power tools as you move through their shop. Then when you need something done... at least you know who to butter up. And their shop rates are usually pretty good if you offer something in return..

I usully ask for cash. Working for less is a bad idea, as sometimes things go wrong.

Never, ever....
Use a grinder on aluminum!!! Sander or flapping disk, yes, a grinder, definitely not. Aluminum is too soft, and will load up the wheel, causing an out of balance condition which sends vibrations and shock loads up through the stone of the wheel. The wheel could vibrate apart eventually(while spinning)unless it is dressed and the loaded aluminum removed. Trying to use the wheel on steel without redressing only makes the unbalance condition worse as now the steel will bump along the surface where the aluminum has bonded and dig deeper into the stone where it hasn't. Redressing will be tough as the dressing stone or wheel will do as the piece steel does and bump along as well. The only way to dress and rebalance the wheel accurately is to use a fixed diamond dresser and move the surface of the wheel across it.

So you want to shave off the equivalent of 3 sheets of paper ?

Cutting is only going to work on a milling machine
. . . then there's the 8ft length.

Maybe a belt sander ? . . . if you don't mind the lack of accuracy.

Why don't you think about pulling a mandrel through the larger piece ?

Or pull the smaller piece through a die.

I would use a bench grinder.

I would tape off where you will stop grinding so you have a reference point.

Clean it up with a hand file and or sandpaper depending on how visible said area will be

Its so small a dremel would as well

Accuracy is not critical.. i am trying to make a small travel trailer for my motorcycle to pull... see pics of the mock up below.

The tongue extends to give me just short of 7feet to sleep on.. and still have room for my tdr

Just use a long auto body block hand sander with variety grit long sand paper strips.

And measure with a caliper as you work the metal...if you just need it to fit ..

It doesn’t need to be within a thousandth of a inch from end to end

I would suggest to just make the body slide on a fixed tongue...
