I am in the market for an electric chainsaw. What do you have and what are the pros and cons?
-
I got two drills from an estate plus a saw , Dewalt 14.4, with six batteries and two chargers. One drill sparks so it is not worth any effort. One battery seems fine and one I would say a step below that. No others want to give a good spin to the drills. Looked at replacement costs and thinking NiMH but what I read said that using NiCad charger for those will cause battery failure. Question is has anyone tried this? By the way ain't no cheap batteries out there , but cheaper to buy new on Amazon than rebuilt.

I saw some new Lithium batteries on Amazon, rated 6kAh (my other ones are 1.2 and 4). These are about $50 for a pair (so get a pair!), roughly half the price of the 4's from Ryo. I cannot speak to longevity, but after several uses, they sure do extend the use time. I was tiring out before the juice ran out, but then I'm more derated every day! I've only looked for the Ryo ONe+ thing, but I assume other compatibilities are available or coming soon. https://smile.amazon.com/gp/product/B08LPP48M1/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

First of all, who decided "Pyrography" would be a good name for wood burning. I can't even spell it, at least as far as the spell checker is concerned. Anyway I have been futzing around in the basement shop supposedly cleaning and reorganizing, well, at least until something to play with catches my attention. I came across a battery charger I was given for parts because it didn't work and I thought someday maybe I could use it to build a wood burning machine. Well that day or I should say days finally came. I opened it up and found the transformer still worked and that is the heart of the machine. The malfunction of the charger happened in the circuit board but I found online that I could eliminate it so I did. The diodes are there to make a correct DC voltage and they are still good but decided just to eliminate the board all together. Here is that circuit board I removed. I noticed the store bought machines had plug in pens and used plugs that appeared to be the same as audio connectors. I didn't want to go out to the store if I didn't have to. Being the pack rat I am I looked around and found what I needed. I drilled the needed holes and installed a jack I had removed from God knows what and hooked the transformer wires to them. To control the heat a standard dimmer switch is connected to the AC power in wire on the hot side. A dimmer switch that powers on as the knob is turned would be preferred over the push on push off style. The heat is adjusted by "slowly" turning the knob and the push type can be inadvertently turned to the highest heat before it is pushed on and blow the fuse. Yep, you know how I know that. Here is a picture of the front with dimmer switch. I put the audio jacks on the back due to space restraints. To make the pens I took some brass rod and used the Unimat hobby lathe to make connectors. I had some small fiberglass pop up tent poles that I cut in pieces for the hand hold. Soldered some audio cables to the tips. I used both available conductors in the wire to carry the current. In use the wires get quite warm and I may have to go to larger wires. I am going to use it as is and see what happens. I'll keep an eye on it and it is not high voltage. 12v. For making the burning tips Nichrome wire is needed. Nichrome wire is what is used for making heating elements. I used a piece from a small space heater. I saved the wire for this purpose when I had a heater I was discarding. Just bend it to what ever shape you want. Comes in different diameters if you choose to buy it. This is just a 6-Amp charger but is more than enough power. I can melt the wire with it. I have played with it a little and found the wire does not need to be red hot for burning but the continuous power is there and holds an even heat. The tip was hot but not red hot when I did this. I'm sure I will need to practice some. Any questions? Ask away.

Recent purchase of hearing aids made me think I needed a box to carry extra batteries. I have always wanted to make one of these slide top boxes so that was the answer.

Ordering a battery for camera online
Smallpatch posted a topic in Machinery, Tools, Research, Reviews and Safety
I needed to order a battery for a camera my daughter gave me over ten years ago needed a battery so I got online and found a great buy much cheaper than the 35.50 for an exact replacement battery. After about ten pictures the battery needed recharging...It was a no name battery from ?? Same thing happened today only now you gotta watch for they now have the almost exact numbers and the picture of the battery is the original picture of a canon battery that came with the camera... The exact battery is still 35.46 from walmart... This is almost exactly what I went through ten years ago or longer and it is still going on today. Then I found the same battery picture with almost the same numbers for 7.99 and freight paid through the walmart site. This is what I ordered or something like this and when I got the battery it was not a canon battery and had to be recharged way too often.. And like then it was too big of a hassle to bring it up with someone and I still have that battery as a back up...The 7.99 battery is not being shipped from walmart and this is what I have run into going through Amazon . I think I order one thing and got something close so guys be aware....I quit using the fake battery for I was afraid it might start leaking acid inside the camera and cost a bundle to put back right. Even the serial numbers is close enough maybe most people stop reading the numbers before they get to the end ...The serial number is not showing on the battery but all the writing is exactly on both batteries. Just take your time when ordering on line and make sure everything is what you think you are getting...

when making a clock should remember when having to change the battery don't mess with the hands..After installing a new battery the hands will automatically go to 12 and stop. Then in a few minutes the hands will start moving again sometimes a full 12 hours without stopping then will stop on the right time. And sometimes they will start again and go directly to the right time..Its good to maybe add a little glue on each corner of the movement for when changing the battery if the movement slips the hands will be off a tad..and like always the movement will advance an hour in spring and fall back in the winter without little hands helping so don't touch the hands... Dave, I'm talking to you!?!?!?

What did you do with your old cordless tools when you replaced it by purchasing a new one because it was cheaper than to replace the battery on the old one, which would no longer hold a charge and the batteries were Ni-cad? Danl

Picked up a 20 volt drill yesterday off of Craigslist. It was still sealed in the box. Paid $40.00 for it because I paid that much for a replacement 19V battery a while back. He had another one that was opened and charged up. It features a pulse mode instead of a hammer mode. I left it in the box, thinking I might give it as a Christmas gift. I though it was made in Germany, but it was from China.

I lost a lot of my hearing during my stint in the Navy, working around jet aircraft. Now I wear hearing aids. The batteries tend to die when you need them most. I turned this little holder for my key chain. Made from Walnut and Maple.
