New customer job

[Stormin 9,983]

 That's some saw. Makes a lovely job. The threaded bar, or even round bar is a good idea for filling the gap.

[Pullstart 63,529]

So, when the blade goes dull, it goes dull right now.  I have a feeling that the scoring builds more heat than simply cutting through, so I’m not blaming the saw in any way.  The local pro-tools store only has 70 blades in stock... so I better hurry before they’re all gone!

You may have already said this above this posting somewhere but what is the corner going to look like? Standard rounded radius?

Yes... maybe... something?  After welding it up, I’ll smooth it somehow.  They will paint it, so it shouldn’t look welded when it’s finished.

Now  now, don't go off on a Tangent !

Let’s hope I don’t need all three of these... at 60 bucks a pop!

 Don't you have any cooling/cutting fluid? Should prolong the life of the blades.

[953 nut 56,742]

        You may want to try making three or four progressively deeper cuts to allow better blade cooling.     Works well with wood router bits.

From my Die Shop / CNC days, I recall that sometimes carbide loves full coolant, sometimes nothing at all.  There’s also such a thing as too little bite or feed rate.  I’ll get all the details figured out.  My second 10’ cut yesterday was sitting on top of 1/4” Formica wall panel stuff, I’m sure that didn’t do the blade any much good either.  I’ll get it figured out some day

Yes straight up carbide likes flood coolant but tin coated solid carbide(read "Exocarb") usually just air blowing out the chips will suffice (maybe an air line regulated down to 15-30 psi some hillbilly fashioned attached so to blow the chips out of the way and cool the blade at same time while cutting )... and again speed and feed and depth of cut all make a difference JMO.

When i must cut or drill things an didn‘t wanna contaminate with oil,

 i use sometimes simply Wax for cooling. Using an rest of a candle.

 

i know it sound strange, but it works, my drills or mills lasts longer since.

If the first blade goes quick dull, it‘s maybe worth a try.

 

[19richie66 17,542]

My son says they use wax on all thier blades and bits where he works. Started using it on my stuff too. I just got an old car paste wax and dip it. Seems to work good.

[Pullstart 63,529]

Even though the shop has A/C, it was just too darned hot to accomplish much but keeping a cold drink nearby and splashing in the water this weekend!  Now that it’s cooled off a bit, I received the feet for the job but he wants it as low to the floor as possible.  I trimmed the bottom adjustment “nut” off the shaft and used a 3/8-16 die to bottom out the threads.  

 

 

[Pullstart 63,529]

My bend points are all scored, now time to trim the edges to size.  Scoring the blank first gives me good reference points for where the edges will come together.  Due to the shape of the base, I’ll be forced to do a couple plunge cuts.  My plan is to clamp the saw base to the work piece, so I can just focus on the cut and not the alignment of the saw.

[Pullstart 63,529]

The front of the blade is entirely enclosed, but there’s a “front of blade” line in the saw base.  It helps to know where to stop in these instances.

[Pullstart 63,529]

My plunge cut worked!  I let the saw tell me how fast to lower it and I braced my arms against my knee for more control and accuaracy.

[Pullstart 63,529]

I’m looking for 46.4 degrees to call it bent!

 

 

[Pullstart 63,529]

Both first bends are done.  I need to pick up some threaded rod or drill rod, and fill in the cracks!

Sweet project Kevin  . Those metal saws are amazing. Sure made cutting a large air duct (round and rectangle) a breeze back in my HVAC days.

What about some hot rolled round stock? Comes in all sizes and cost less.

Me too!  It’s a bit behind schedule due to storms coming through this weekend knocking out their power.  They picked up a router table to plane the married slab to finished thickness and I’ll wait for final thickness before I finish my part.  He has a very specific final height in mind and I don’t want to stray from that if I can help it.

This has been a pretty awesome thread and I thank you for sharing it Kevin.

 

one of the customers I had at my old job was just outside of Boston Massachusetts. They used to be very very high-level specialist Carpenters. Very fine finish work. It was mind-boggling to me that those guys could make seams in tiger maple that you could barely, if at all, detect.

 

One of the projects that they did was for a guy down on Cape Cod who had a very large tree. Species, I don't remember. It was on old family land and it had gotten past its life expectancy and they began trimming it from the top down so as to save a piece from the middle that was three or four inches thick ... 4 feet wide and 10 feet tall. Of course that turned out to be his desk.

DESK? Sheesh!

[Pullstart 63,529]

Just to be clear Eric, I’ve never worked with 3/8” plate before, more have I married steel and wood in this manner.  A lot of the jobs that come my way are because people ask me if I CAN do something, to which I answer yes.  They don’t ask me if I’ve done it before!  I gain confidence in small things, like tractors or golf carts.  Then when it comes time for say roll cages or tables, I have the experience to understand the steps to take to find that finished product.  The next few days of work is going to be fun stuff, seeing it all come together!
