i have it for more than 1 year i guess..sturdy in term of stability,yes. portability, yes. strong grip, yes. but if to thread the pipe, it can't hold the pipe strong enough to prevent it twisting that's why im using the pipe clamp ( the red tool ).

When tapping the pipe, the pipe have to get nearer as possible to the clamp side.

Your pipe threading pic remind me back when I tapping alot of GI pipe with the pipe clamp similar to your pic. But different stand.

you should have invested in a pipe threading machine instead if got big volume of pipe to thread  biggrin.gif  brows.gif

last time, some hardware shop do offer pipe threading services...but nowadays, want to find 1 also hard... sweat.gif  sweat.gif

Have the threading kit same as your wan. But don't no where is go.

Operate before those threading pipe machine. Very convenient and fast.

I know some hardware shop still provide such service around my area and further a bit. Did brought from them before for custom length with treading.

Probably not much people use GI pipe nowaday. All want use PVC.

Last 2 yrs when ask a plumber to install a filter outside my house. He take more than 1/2 aday to do. A simple GI pipe modify at the meter.

ya wo...many years back, plumber quoted me quite a high price to do some gi pipe modification ( to install water filter ) can't remember how much exactly ( definitely more than rm200 ) and need almost a whole day to do it  ranting.gif  end up i diy myself with pvc pipe instead.

now with the tools at my disposal, nothing is impossible d  biggrin.gif

Regret ask him to do. Not sure why I ask plumber to do. bangwall.gif I think got to do with the underground pipe which I cannot access. hmm.gif

Should just DIY. Get the pipe from hardware with thread.

Probably only take 2hr to complete.

You need to calculate the feeding speed. Too fast definitely will broken the cutter.

And if the cutter is blunt, the speed need to slow down some more.

Search for the feed rate fomula calculation.

I forget the math.

But normally I will use the cutting sound and the surface finishing as the general guide to dertermine the feedrate is too fast or slow. (for metal machining)

Made a crosscut sled over the long weekend.
Surprisingly nice to use.
The accuracy is about 0.2mm variance on straight line cut.

Crosscut capacity is 12 inch with the saw cover on. With saw cover off can crosscut up to 22 inch.
Miter saw can go to storeroom soon.

Hi, where did you get your Makita Cutter? I've been looking for the same item, but yours have different coolant bottle. That brass pipe/tube look better than most plastic I encounter..
*
Amazon. During black friday.

That coolant bottle is for cutting tile or wall to cool down the blade.

But the bracket is for the old model. Need to modify for this new model.

Yes. From amazon too.

Coolant bottle is an option part.

That brass is a valve to control the water flow rate.

I have been looking for a master/slave trigger switch ever since I finish building my dust collector. Those available in amazon works at 110v and freaking expensive.
Don't even know where to find it in Malaysia, then I found this circuit board that has the master/slave function in taobao. Bought it and build my own master/slave switch, it works. biggrin.gif

Its to use with my dust collector.

Master = Table saw/ band saw/ things that make dust
Slave = dust collector / vacuum

When I turn on the master, salve will turn on too.
When I power off the master, slave will turn off about 10 seconds later.

Very useful as I dont need to walk to the dust collector turn it on, walk back to table saw, walk to dust collector to turn it off...
Gets tired when I need to make many cuts, also reduce noise especially the vacuum.
*
Why not direct wired the master to slave?

For the delay timer, just wait another 10sec and off the master.

I need to let the dust collector runs for extra 10-30 seconds after machine turn off to clear the residue dusts.
Anyway a jig to turn off the DC after some delay sounds more cool.  tongue.gif

But this board need a DC to run ?

Need a DC power supply ?

Nope, the power for the chip and relay is already supplied by the circuit build into the board.

Understand. I can see the switching power supply there.

There is a few way to do it. 1 is your way.

Easy way and standard available --> https://forum.lowyat.net/index.php?showtopi...post&p=65006671 or https://www.aliexpress.com/item/Free-Shippi...f6-fff8b63f2dd6

Another way is a AC delay timer. This timer can find at any eletrical shop or pasar road. https://www.aliexpress.com/item/AC-250V-5A-...d0-c4ddec92d7fc

Or can use any normal AC timer as above (not delay) with can get it at any electrical shop. Use a 2 way switch to make a circuit.

The lighting control switch is not suitable, some machines are more than 1500w so it will blow the switch.

The AC delay timer thing is more suitable I think but I wonder how the timer starts counting? Not really familiar with electronics.
The master machine can operate from short 5 minutes (table saw) or 30 minutes++ (sander/bandsaw), if the AC delay timer can start countdown after the master machine is power off then it will be a good alternative. Looks more robust too.

Btw thanks for pointing out that grey color thing is the power supply. I keep thinking that is a capacitor.
*
The circuit can be wired in this way (pic) for the delay timer. Once you off the switch, the timer will run. Once time up, the timer will switch over and off the dust collector.

It reset by switch ON again.

The machinery doesn't go through the timer. I think you don't want a timer to control your machinery. Only the dust collector is go through the delay timer.

Once you off the master, all your machinery will OFF. The dust collector still running till the timer time up.

Yes. DC starts whenever I power on my table saw or machines that connect to the master socket.

Here is the link to the product. Its in chinese.

Can you explain what that I highlight mean.

Sorry. I don't no mandarin.

The

1st - timer control output
2nd - Live from source
3rd - ??
4rd - Neutral

All your machinery and dust collector go through the timer?

My connection is a bit different, here is my connection  sweat.gif
1 - slave live (DC)
2 - live for wall socket & Master (table saw & machines)
3 - neutral for master & slave
4 - neutral for wall socket

The connection in the chinese diagram should be
1 - slave live (DC)
2 - live from wall socket & Master (table saw etc)
3 - neutral for slave(DC) & wall socket
4 - neutral for master (table saw etc)
*
Thanks. Understand.

The relay is ON/OFF control the Live. The neutral (3) is pass through I guess. (from your pic)

For your connection, the machinery (table saw & machines) is not go through the timer delay. I guess you need to ON/OFF 2 switch ? When you done and go out, you OFF the switch 1 and 3.

From your pic wiring and explain, should be this way probably
1 - Timer delay switch for dust collector
2 - To dust collector (timer delay)
3 - switch for Master machinery. (table saw & machines)

I uploaded a diagram I draw.
1) The main wall socket controls the power to everything, so make sure total power draw can handle by the socket.
2) The slave mode toggle controls whether the slave socket will be triggered by master or always on. Lets say I want to use the duct collector to suck wood chip on workbench then i just toggle the switch to turn on the DC.
3) master socket goes to the machines, the machines has individual on/off switch on them to start. So the master socket is always on power.
4) the slave socket behavior you can refer to item 2.

I use the sockets with power switch coz hardware store only sells that. The on/off switch on the socket also acts as another layer of protection just in case, I hope.

[attachmentid=8864496]

That's ok. Wiring how to control is depend individual.

I mistaken your master/slave meaning. Cause I thought Master switch is to ON/OFF everything. (Only 1 switch)

No more power to all your equipment when you walk out.

Sorry I draw the wrong diagram above. blush.gif The dust collector which control by the delay timer will not run if the master switch is OFF.

It should be in this way the wiring. Another wire need to be pass the master switch to the delay timer. (Red). Once you off the master switch, everything will be off. DC will be off after the times up.

I draw another diagram to represent the difference in the design.
1) The main switch does not turn on the dust collector when the main switch is turned on.
2) The dust collector (slave circuit) is turn on when current sensor on the master circuit sense a current draw. The current sensor also set the time to stop the dc when no current draw is detected.
3) The switch inside the table saw is responsible to turn on/off the slave circuit by increase/stop current draw on master circuit.
4) When the main switch if off all power to DC & table saw is cut off immediately.

With this design I don't need to walk to the main switch to turn off the dust collector, just turn off the machine and the DC will turn off later.

This ? https://www.aliexpress.com/item/Free-shippi...0a-5ae662f03933

You need each of this to connect to DC if more than 1 machinery.

Probably I will use timer and relay circuit for such switching. More reliable.

That current detect in aliexpress would work but it will require additional companents.
I will stick to the current one I have as I not good in electronics.
Durability... well, see how down the road lor.  smile.gif

The aliexpress wan is same as what you want. Require DC power supply. But I think don't have delay timer function.

If talk about durability, I will go for hard wire. Like timer and relay circuit. There can last guarantee at least 5yrs. 10yrs is no problem if using jpn parts.

Only go for electronic if no choice.
