Realizing that I'll be pretty busy for the next few weeks,

I decided to build my homebrew key for use in the May WES well in advance.

Here's a picture:

Used a bunch of hardware on hand, including the bearings (which have been sitting around for a good 40 years).

One trip to Lowe's was sufficient for some various pieces.

No spring - used two magnets in the back.

It feels pretty good, but the knob winds up being quite high.

We'll see how my arm does during the WES.

Given that the contest is on Mother's Day weekend, there are some limitations to my operating time.
If anyone else wants to post shots in advance, it would be neat tore the other guy is going through during the WES QSOs.

Home Brew key pics?

Mine is a 3d printed key which features....
Built in pixie radio @7.110, 8 AAA Batteries. 12v, So-239 connector, A single roller skate bearing.
Only one partially visible wire, Sidetone fed back into lm386, 22lr rifle shell contact points, A single pen spring.
Bonus equipment is... matching powered speaker and matching dummy load.
I'm going to send the whole thing to my friend in Florida when I'm done playing with it this weekend.
I've made the key project public.

If you would like to tinker with the model here is a link.

Here are some photos... Please share photos of yours!

I, for one, appreciate the use of rifle shells in your key I'll #metoo this.

Bakelite for bug paddles #Bug

*** Just Google Bakelite substitutes which I just did and you will find Tufnol is the material.

Bakelite is a thermoset plastic material.
*** If you don't mind it coming from China, eBay lists: Bakelite Phenolic Flat Plate Sheet 300 mm x 300mm x 5mm Black For CNC
*** Pour your squares in black/brown pigmented polyester or epoxy, both are thermosets, like bakelite.

If needing multiples, machine a negative shape in polyethylene or teflon and cast the needed squares as above but already milled.
*** I'd recommend Delrin.

It machines beautifully, strong and stiff, completely opaque, and the surface is really low friction.

For this application, if you need a final thickness of 1/4" I'd recommend starting with a piece 3/8" or 1/2" thick and milling it dead flat:

*** Garolite would probably be most similar to bakelite.

It has fiber such as cotton or sometime fiberglass in it.

Sometimes you see gears made from it. 
Delrin is very machinable but not as hard and rigid as bakelite.

It is harder than nylon but not a lot harder.

It was basically formulated for machinablilty.

Comes up on the McMaster-Carr website when you search "bakelite sheet."

PB213 key by Phil Boyle G0NVY

Hello Everyone,
I;ve tried to like this key, but its just not my cup of tea...Its a fantastic quality built copy of the Marconi 213 by Phil Boyle G0NVT ... More info at this link;

I just find that I really prefer my cooties or Bunnell Triumph style keys for daily use ... Mine literally has only had 2 or 3 QSOs made with it and Phil is always backlogged on orders .. So if anyone is interested I;d let it go for $200 + 12.65 shipping ... ( Original cable is included although not pictured)
I'd consider trade/cash deal as well ...

73 , DR, N1EA

I'm slowly getting better with my sending arm after surgery and have been using a Bencher iambic paddle,,,,,,,,,

gizmo since my arm goes spastic using a straight key.
I'd like to try using a cootie as some here have recommended.

Does anyone here know of an inexpensive cootie, could even be second-hand/homebrew?

VIZ cootie is $110 plus shipping, more than I'd like to invest in case it doesn't work out.
