Roll it on with Cyano!

I use "wet & dry" rather than sandpaper, wrapping it around pencils, marking pens etc, with med cyano... great for the wing fillets

Well started Pat!!

Fantastic soldering jig Pat! I have used clothespins for a couple years now, and never thought of how to get them aligned and standing up easily. I have wedged and taped and stuck them in my vice, all to unsatisfactory result.

I also really like the Coaming cutter. Straightforward and effective.

Thanks so much for this thread.
I have a little thing for cutting foamy bevels that went around here on the threads about a year ago... Basically just a single edged razor blade screwed to a peice iof triangle stock so the blade sticks down about the thickness of the foam you are cutting. line it up with a ruler and drag the jig along the ruler. perfect straight cuts at a very usable angle. I'll look for mine and shoot a pic or find the old thread.

Pat,

Great thread!

I can only expand on your clothes peg idea by using one to hold 4mm connectors vertical whilst soldering on the battery cables.

Ooops! Nearly forgot this pic of the correct tools to use when tightening a propnut..........

i like the soldering idea pat, i use a similar idea using a popsicle stick and 2 clothespins, then the clothespins hold down the wire flat om the popsicle stick while i solder away..

Tim, better to push the male connector in a female one, to act as a heatsink and prevent the leaves losing their springiness. I prefer to clamp it directly in the vise for the same reason.
Now show us that specially prepared crowbar you use to block the S400 while tightening that propnut......

Plastic Sandwich Bags and C-Clips

Put that GWS gearbox in a plastic bag while removing the C-clip, the C-clip won't "de-materialize".

Attach a length of wire to the radio antenna when you are trying to pull it through the fuselage and out the tail.

You can easily make your own pull-pull connectors out of small cotter pins and Dubro e-z connectors and Kevlar thread. I install brass eyelets in thin ply sheet control horns so that the Kevlar won't saw into the ply.

A little CYA holds the tiny Phillips screw to your jewler's screwdriver while you attact the tiny servo arm to the servo.

I use my vise grips as a vise to hold Deans Ultra connectors while soldering wires to them.

Gents,

The most vital tool that no one of us can do without is a head-full of smarts. The older I get, the more I realize I have much, much more to learn about how to do the right things the right way!

Here's another variation on the triangular stock cutter. Can't remember where I originally saw it but it is good!

Maybe I am using the wrong word. I meant the springy parts of the male plug that provide positive electrical contact to the female plug. Too much heat from soldering, and they become "heat treated", taking away the internal stresses but unfortunately also their springing quality, which will result in a poor electrical contact.

Why waste time and effort? A 1/2" drive air/impact tool can be adjusted to around 150 ft/lbs, and the spinner banged back on like an old hub-cap...

then there's always that old, cold chisel.....fits anything

A notch cutter can be made by gluing a piece of ply the thickness of the desired notch edge on to the back side of a piece of sandpaper. Trim the paper even with the edges of the wood and you can sand notches in trailing edges and formers in a heartbeat.
