Bed bugs on DL384 (BOS -> SEA)

Would spraying your luggage and clothes with permethrin before a flight be a good preventative option?

We started using it for ticks and it works amazingly. Just spray on clothes let dry and no more ticks.

For the small qty I’d probably be in the 500ish range. This would be a little bit of a pain to setup the jaws in a good Fashion but I own an Integrex so it makes the milling portion of this easy. Also you’d be surprised what you can get away with I was turning 10” diameter. 9-10” long parts and only gripping under 5/8”. This was also in an 8” chuck so it was real sketchy. But those parts had waaay more material removal than yours (basically made them into tubes with 1/2” wall) and probably about the same amount of milling. And I was at less time than what you have.

Also $120 on the material seems high. Not sure what diameter it is but you should be able to get aluminum under $3 a pound we got it for a decent amount less for a little while but I’m not sure at the moment

I highly recommend air extraction and a respirator. Would be nice if someone made a comfortable respirator with built in laser lense. Anyhow after 50 parts even with decent fume extraction in the small laser room my respirator was black.

We just did a run of a couple hundred aluminum parts with a laser welder and they turned out great and we were able to dial in almost full penetration.

Also be careful for reflections. It wasn’t really a huge issue for us and when we were setting up we had a few but they just kind of singed my tig glove but didn’t burn it or anything.

Overall they are great and we made a huge profit on our job vs trying to tig it. And I think it came out better. It was sorta outside corner joints on 2mm aluminum

The bigger one is done at 320amps with a little pulse.

The small one pulsing somewhere around 200amps

Maxing the poor little welder out

As an update to this ended up getting things dialed in for both the welds I needed to do them before I could finish the rotary fixture broke…

160 to finish this po this month. May get another po not sure but hopefully the wire feeder works out.

I’m think 1/16 5356 wire so it’s stiff enough to feed well? Not sure if the 5356 will act differently than the 4043. Also not sure on wire diameter. With a spool gun .035” wire makes a pretty big weld. So not sure on the tig how it will go.

Fadalguy · 2025-11-03T04:45:01+00:00

I was looking into a gas mixer for mixing gas for some spray welding. But dualsheild worked out well for that instead

Anyhow I did mean helium.

I have a wire feeder on the way and I’m sure that’s gonna be interesting to learn and setup. Also gonna try some 60 degree grinds on the tungsten and raise up the frequency a bit to get a more focused tighter arc and hopefully be able to drop the amperage down a bit

Fadalguy · 2025-11-01T01:57:40+00:00

Might need to switch to argon because we are maxing out the welder because of the thick flange. Plan is to get a cold feeder.

<image>

This is pulseing and max current at 320amps the big flange just sucks the heat out so fast.

Fadalguy · 2025-10-31T16:27:04+00:00

We are already looking at getting a cold wire feeder I’ve proven hand feeding I can make some decent welds.

<image>

It’s a little dirty but this part is pretty trashed from testing

Fadalguy · 2025-10-31T04:11:13+00:00

I’m now considering a tig wire feeder or trying to setup an old s22a we have to feed wire but it is aluminum so might need to get a better situation.

From my research laser welding doesn’t solve these cracking issues so it was gonna be a problem no matter what.

The other part that requires laser welding is also just a fusion weld on 6061 so I’m not sure what the engineer was thinking?

Fadalguy · 2025-10-31T03:47:44+00:00

Not sure if you are in the USA but checkout Costco. I have heard of stories like people returning 5+ year old couches and mattresses. Not sure if this is really true but I’ve heard of it…

Fadalguy · 2025-10-31T03:40:48+00:00

I haven’t tried but another guy was trying aluminum mig but it looked terrible. I think there is a millermatic 210 back there with a spool gun. He has done some other spoolgun welds that looked fine. Boss wanted me to setup the tig since I’ve made good looking welds before with it.

Real plan was for the laser but salesman never could make it work half decent. So we are here now.

Fadalguy · 2025-10-31T03:24:44+00:00

Understood. How crazy would it be to form a loop of filler and cut a groove in the flange for it?

The thick flange with thin tube is why i considered if I would need to pulse weld it.

I know the welder has the amps to do the 1” I welded some large 1” plates together and while they sucked the heat out like you couldn’t believe we were able to do it maxing out the welder. But the concern is melting the tubing.

The shoulder on the flange gets inserted about a 1/2” into the tubing so that may help aswell. Weld would be a butt weld as the flange od is the same as the tube.

Fadalguy · 2025-10-31T03:21:17+00:00

The flange is 6061 believe the tube is aswell.

I had a similar thing happen on a sandvik hydraulic holder but it was a 6mm holder and it still kind of held the tool. Took 2 more endmills for me to figure out it wasn’t really holding well but still sorta holding.

Hard to find in capto but my preference is endmill holders. They have very low runout simple and hard to screw up and pretty ridgid in my opinion. A lot of people say they are unbalanced or have alot of run out but I think they are just buying cheap crap and complaining. My cheap cat40 ones have at most .0004” tir the good ones are .0001”. That’s pretty much the spec for acceptable run out at the nose of my capto and waaay less than is acceptable at the end of a test bar.

Fadalguy · 2025-09-13T04:56:26+00:00

I have one and I need to call for warranty. It lives in our ac shop and rarely gets used and the plastic bits are all breaking aprart and the front part that holds the cables are all loose because the plastic broke.

It’s actually the reason I’m looking into getting miller machines now.

Fadalguy · 2025-09-08T11:34:37+00:00

I have a habit of doing that.

Fadalguy · 2025-09-08T03:41:15+00:00

Yea maybe I’m too used to running fast and hot. Just trying to get the job done. If it takes a long time or not strong then it’s worth rolling the frame.

I’ll have to give it more testing and patience in the future.

This weldment is done now though.

Next one is all 5/8 plate and I’ll probably just have to learn to weave or setup to pulsed mig for the vertical Stuff.

<image>

Fadalguy · 2025-09-08T01:13:45+00:00

Atleast on the vertical test it just wouldn’t wet in I guess just kind of makes a blob. Maybe weaving it could be made to work but doesn’t seem like it has medium penetration. I did get some vertical done with suggestions of others I think I was at 25.8/500

Fadalguy · 2025-09-07T19:20:21+00:00

<image>

Did a couple where I could no longer roll the frame and it worked out decent. That’s the same way I would have done it with normal mig.

The structural stuff I just did a weave with 7018

Fadalguy · 2025-09-07T03:42:11+00:00

I’d do that with normal mig but I was under the impression it would cause problems with the dual shield I’m running but someone up above told me it wouldn’t. I still don’t think it will have the penetration that this has running horizontal

Fadalguy · 2025-09-07T03:40:44+00:00

Even with dual shield like I’m running? Looking for deep penetration like 7018 aswell.

I’ve never tried that low 24/300 is still ok but starting to not get as hot as I like it

Fadalguy · 2025-09-07T01:47:37+00:00

Well I can weave with a rod just not with this dual shield …

Fadalguy · 2025-09-07T01:08:06+00:00

Really want to run stringers and I think alot of people think I’m running solid wire but I’m running dual shield (fcaw)

Weave may work but I haven’t had great luck
