The EU RoHS had mandated the use of non-toxic solder which does not contain lead. The result is solder mostly containing tin. This is weaker than the previously used lead-tin solder and stress cracking is common. For example, a particular graphics processor unit that my friend had used to stop working from failed solders. This was known problem and he managed to fix it twice by actually baking the board in the kitchen oven!

In addition, tin has the strange tendency to grow "whiskers". These can touch whiskers growing from adjacent solder joints and cause short circuits. This is a big problem in surface mounted device boards where gaps between solder joints are very small.

Dremel is advertising their 'not just for professionals' 3D printer, and laser cutter/ engraver. In this forum you are the person most likely to get your hands on one. If so, pls. give your feedback.

I was talking to a couple of model building fanatics this very morning at an event in Rotterdam. Their model club is investing in one of these.

I am very tempted. But a long list of stuff I need to spend money on when it comes to my cars, house, photography first. My wife has not forgotten I already invested in a 3D printer with friends some years ago. The rules of a happy marriage, you can not win when they ask “what is wrong with the one you have got”. So I am not even going there at the moment.

What is very interesting is 3D printer service. Which means you do not invest in the printer yourself, but your 3D designs get printed on some very professional machines and send to you overnight.

So much stuff to explore and try and so little time!

What is the street price of these two systems? In US and EU.

In my neck of the woods laser cutting and laser marking services are available. Not so for 3D printing. Maybe with the industrial downturn some organisations which used it inhouse will start offering it as a service.

Rough idea for European prices:

3D45: approx. Euro 1700
3D40: approx. Euro 1200

So that is the price of a good bicycle.

Or you can go second hand. UKP 800 will get you this:

I have always wanted a cordless impact wrench, and finally it happened. The small one has 285NM of max fastening torque and the big one has 1000NM of max fastening torque. Unfastening torque is not mentioned but is usually higher than fastening torque. Has three torque settings.





Best deals can be found offline (like for most power tools) do not buy online in India.

We use Bosch cordless impact wrenches at work. In my experience, the smaller one can only properly tighten fasteners upto M8. Anything larger requires final hand tightening with a spanner.

I don't have any experience with Makita but they should be similar to Bosch in performance.

The stated torque is enormous! 1000 Nm is the equivalent of a 100 kg force on a 1 m long bar. This is very difficult to do manually.

This is for DTW285 (small one).
Standard bolt M10-M20
High tensile bolt M10-M16
Max fastening torque 280Nm

This is for the DTW1002
Standard bolt M12-M30
High tensile bolt M10-M24
Max fastening torque 1,000Nm

Small one is good enough to properly tighten the lug nuts of my innova (tested) though its not recommended practice.

That's nice. What is the reasoning for buying two?

Just wanted to have the DTW1002 and there is no other reason, honestly its overkill for my use.

Oh, fine. Tool Acquisition Syndrome. I know it well.

Enjoy! :D

Wow Nice!! The smaller one would be useful to handle in tight areas. The bigger one would be brute force:)

How much did it cost you from from where did you purchase it?

Nice ones, always good to have two!

As it so happens, I am in Dallas, USA this week on business. I got up at 0400am this morning as that is 11.00am my time. Of to the Starbucks and by 0600am the Home Depot opens. Love roaming around these huge DIY stores. Got very good selection of tools and just about every gadget you can imagine and then some more. Just a few piccies to give an impression





I can never ever not buy anything in these shops. Got myself a new pair of leather working gloves and this set of three LED Headlights. Both were on special $ 10 each.

I also managed to find mole poison. Can not get that in the Netherlands. I tried traps, (carbide) gas but the mole just laughs at me. But with this stuff he is going down!



I am planning a visit to my favourite tool Harbour Freight later this week. I also need to get a new iPhone and I will be buying some clothes! I might do some work too!

This is what we use: https://www.bosch-pt.co.in/in/en/pro...250-06019D81F0

Same torque as the Makita.

The biggest benefit is the speed of tightening fasteners in production. That makes a big difference when there are hundreds of fasteners to tighten. We always check M10 and larger fasteners for tightness after one bad experience.

Wheel nuts world not be a problem for tightness since they have fine threads, not the usual coarse threads of standard fasteners. They tighten with less torque.
