BSA Red Dot RD3022SB Gummy Sticky problem

Recently I happened across my BSA Red Dot  RD3022SB site which I had not used in many years. It was stuck in a drawer in my work room. I went to pick it up and it was horribly sticky. It seems it was coated with some kind of non slip compound that for unknown reasons had turned gooey.

Using my googlefu I found many forums with people reporting the same issue. most of them just got rid of the site saying it was impossible to clean. Other people reported it could be cleaned with alcohol but that was very laborious. Many people reported that Acetone did not work.

Here is what I did to clean mine.

You will need:
Real Acetone (your wife or girlfriends fingernail polish remove is NOT acetone).
Denatured Alcohol.
Thick Nitrile or Rubber gloves (5 mil or thicker).
rough paper towels.
q-tips.
a respirator or work outside.
Patience.

Put on the gloves and respirator (acetone is not good to breath or have on your skin).
If you have the lens caps put those on so you don't get acetone on the lenses.
Pour a liberal amount of acetone on a folded up paper towel and begin soaking and scrubbing the goo off. It will take several passes to remove it. You will know the gunk is removed when you see the greenish black anodizing under it. I was able to go over all the surfaces and no paint or anything was removed that I did not want removed.

Now go over all the cracks and crevices with q-tips until no more black stuff comes off on to the q-tips.

Remove the lens caps and using q-tips carefully clean around the area that was covered by the lens caps and around the lenses (avoiding contact with the lenses).

Next put the lens caps back on and drench everything with the alcohol and wipe that off. clean the lenses with soap and water. You are done.

The Worst Car Radio/Stereo in the World

I have a 1989 Chevrolet c2500 that someone took out the original stereo and head unit and replaced it with (what I would describe as) the worst radio I have ever used.

The radio was a Pioneer DEH P400UB I hate this thing with the hate of a thousand suns. Attempting to do anything with it while driving results in nearly wrecking the truck.

Replacing the OEM unit appears to be more trouble than it would be worth.

After lots and lots of searching I finally found a good simple to use stereo.

I got a used stereo from a 1998 Subaru Legacy. It was one of the few stereos I could find that also had lots of information online. 20 watts per channel, 4 channels, cassette tape, lcd display and simple easy to use controls.

The unit looks brand new inside and out, mounted it this morning and was able to drive around manipulate the controls with out hardly looking at it and never once came close to wrecking as with the Pioneer.

Also sound real good not quite as sensitive as the one in my 2015 forester. Made by Panasonic.

I have a cassette tape that can connect to an external device, a cassette that can do bluetooth, and a cassette that can play mp3's.

I took the Pioneer radio and put it on my bench to mess with it. Even sitting on my bench where I can give it my full attention I cannot control it easily. It has a single knob that is also a joy stick and a button. It has a remote control but that still does not make it easier.

It works like this when in tuner mode:
the knob is rotated for volume
you move the knob left and right to tune a station
moving the knob up and down selects presets.
the problem is when you try to do this while driving you have to remember what does what and the slightest wrong movement will result in changing the station or moving it off frequency.

Then there is the problem of mistakenly enabling demo mode. if that happens the radio can't be turned off and you have to consult the manual to do that but the manual skips steps and is badly written.

then the other buttons on the radio have multiple functions which change depending on what you are doing. The Pioneer DEH P400UB is a $200 driving hazard distraction radio from hell. Though it does sound good it does not belong in a car.

Don't get me started on the trouble it is just to change balance, fader, and tone controls.

Makita to Skil/Bosch Battery Adapter build

I had a bunch of Skill cordless tools but no battery for them, instead of buying batteries and a charger I found a way to make an adapter to connect my Makita battery to these tools


There are USB adapters for other manufacturers that you could do this with.
Milwaukee
Dewalt
Ridgid
You could make many combinations of adapters.
