Introduction: $10 DIY Flexible Soldering Helping Hand

Picture of $10 DIY Flexible Soldering Helping Hand

Soldering can be Frustrating if you don't have a pair of extra hands to hold the job while you are soldering it ,Here comes into play the job of third hand also soldering helping hand.They help a lot in doing a great job . When I started my journey I had the metal one it helped a lot but it was getting old and also some case it lack flexibility which I need for some projects. I think you will agree to that extra pairs of hands can make a lot of difference.In this Instructables I will show how I mad this awesome Flexible Four Arm Soldering Helping Hand, This is my first woodworking project , so am sorry could not be in details. Thanks to Instructables classes I learned a lot about woodworking.

This project is made for the build a tool contest , so if you like it do vote for it

Step 1: Cutting the MDF

Now I know many would come and shout, "you should use a heavier base ."

I had used MDF 7.5 mm in width because I had it lying in the space and I don't like the stone base.

You can really modify the project to what you have access with.
I had attached a rough template of the dimension of the cut I did in this project, or you can use ur on dimensions.

This was my first time with a jigsaw so it was not perfect, I will try to be better next time :P

Step 2: Smoothing the Cut

Picture of Smoothing the Cut

The cuts that came out of the Jigsaw were not smooth, so I sanded the edges first with a 220 grit sandpaper then I repeated the same with a 320 Grit fine sanding sandpaper.This process takes a bit of time but you will eventually end up with a very smooth surface.
Tip Join the both piece with a C clamp and then sand the time will take short and will be more even .

Step 3: Join the Both Piece

Picture of Join the Both Piece

After finishing with the sanding process join the both piece together with some wood glue and keep it in place with clamps I had used 2 2" Clamps to keep the things in place. Now depending on the glue cure time varies but my one took roughly 25 mins to cure.

Step 4: Final Smoothing

Picture of Final Smoothing

After the glue cured I did a final sanding to make all stuffs clear before going for the painting .

This time I used only the 320 grit sandpaper.

The sanding also removes any type of glue that came out of the joint. Any glue left in this position will not make the paint smooth.

Step 5: Drill Four Holes

Now to attach the Hose flexible water coolant with the MDF you need to first to Drill Four holes. You will need to use a 12 mm spade Drill for these. You can also use Forstner bit also bor made the job done .Since MDF is soft material it is easily drilled without tear out . If you use plywood it will have tear out .

Here is the video showing how to use a spade video.

Step 6: Painting the Block

I have alot of pizza box lying so I used it to paint the block .Btw do you what else can you do with a pizza box .

anyways let come back to the painting

How to spray paint properly

  • Shake the can
  • Press the nozzle
  • Uniformly apply the paint
  • let it dry
  • After some time apply a second coat
  • dry again

Step 7: Preparing the Glue

Picture of Preparing the Glue

The arm can go through a lot of wear and tear so I decided to use epoxy double agent glue.
Epoxy is a two-part formula that requires equal parts of resin and hardener mixed together for activation. For best strength results, mix a 1-to-1 ratio of resin and hardener

Epoxy adhesives are a major part of the class of adhesives called "structural adhesives" or "engineering adhesives" (that includes polyurethane, acrylic, cyanoacrylate, and other chemistries.) These high-performance adhesives are used in the construction of aircraft, automobiles, bicycles, boats, golf clubs, skis, snowboards, and other applications where high strength bonds are required. Epoxy adhesives can be developed to suit almost any application. They can be used as adhesives for wood, metal, glass, stone, and some plastics. They can be made flexible or rigid, transparent or opaque/colored, fast setting or slow setting. Epoxy adhesives are better in heat and chemical resistance than other common adhesives. In general, epoxy adhesives cured with heat will be more heat- and chemical-resistant than those cured at room temperature. The strength of epoxy adhesives is degraded at temperatures above 350 °F (177 °C).
Some epoxies are cured by exposure to ultraviolet light. Such epoxies are commonly used in optics, fiber optics, and optoelectronics.

Step 8: Applying the Glue

Picture of Applying the Glue

Now gently apply the glue on the bottom thread and press it snugly with bottom base . Repeat this Step for all the four Arms. Let the glue cure for overnight .you can also apply a small layer of epoxy glue around the joint to give extra strength to the system.
The epoxy bond will show its magic the next day you wake up .

Step 9: Comparison and Future Imporvement

Picture of Comparison and Future Imporvement

Look at my old helping hand and the newer one it is a Gaint in comparison . Four arms help in additional holding capability. I can easily solder now, keeping the led straight with these.I hope you guys liked it .

I made it using a metal cadbury chocolate box and I have added a fume extractor and soldering iron holder to it also!

KeithG56 made it! (author)2017-08-10

Made it - awesome Instructable, thank you! A slight difference was that I had a spare lamp base (from an Ikea LED lamp I wall mounted) so I used that instead of the MDF blocks.

Can you give another link(Indian) for the alligator clips.The product seems to be discontinued.

Good Idea!

But what if you wanted to make it even simpler?

No drilling with a huge drill bit, and no gluing!

I found that if you remove the orange screw-in part of the hose completely and toss it, you can then remove the lowest blue segment and screw it directly into your base. Choose a screw (or bolt) with a head that is a bit larger than the hole in the bulb end of the segment. Not too big, otherwise when you snap the rest of the hose back onto this bulb, it won't fit well. I can't believe how simple this solution was! I'd seen so many of these tutorials and everyone was always having to come up with solutions for those damn threads -- Never again!

Very handy!

Nuonaton (author)2017-03-21

This is great! Much better than the old style helping hands!

Srijal97 (author)2017-02-14

Great I'ble!

I feel that some parts of the video could have been fast forwarded and made shorter, but thats just my opinion! :)

Mihsin (author)2017-02-10

Good idea

H. DeanR (author)2017-02-09

A mask when cutting and drilling the MDF is certainly in order. The dust from it is different than with plywood or solid lumber; particularly nasty stuff. Great Instructable. Making this is definitely on my to-do list! Thanks

woodlouse (author)2017-02-07

Where do you get the flexible arms. as they seem to be the most important part of the build?

geekrex (author)woodlouse2017-02-09

see the links , i have listed it

lightweight1206 (author)2017-02-08

that base is so small, are you sure its stable enough?

geekrex (author)lightweight12062017-02-09

Ya it is pretty stable

ACdB (author)2017-02-07

Top, great ideer, i have items ordered at Allieexpress.

Thanks

MattP9 (author)2017-02-07

i love this and is it just me or does this make anyone else think of dr. octopus ? AWESOME

RADCOMj1 (author)2017-02-07

Well done great idea.i could see ot was your first time with a jig saw...you need to get the liece to be cut stabke on a surface..o also thought you were going to drill into your hand. Massive thank you for sharing with us ?

Elwynn (author)2017-02-07

Some of your links are not correct and there is no picture of the assembled product.

geekrex (author)Elwynn2017-02-07

Sorry There was some issues which I have correct thanks for informing mate

geekrex (author)Elwynn2017-02-07

Can u say which link i will correct it as of now i guess its the clip .
Btw i have the pic have a look properly .

batfastard made it! (author)2017-02-07

I made a set of these a couple of years ago. Best 'helping hands' tools I've ever had.

Surajit Majumdar (author)2017-02-06

Great built :) voted for u

wqk (author)2017-02-06

Look, bared his teeth like a dragon!

RoguePirin (author)2017-02-05

I guess I spoke too soon. However, the link to the alligator clips goes to the arms.

RoguePirin (author)2017-02-05

This looks great. However, all of your links point to the same thing: the flexable arms.
