Re: Need recommendation on a Automatic Battery 24 charger.

Assuming that the 4 batteries will be wired in series that gives a 24 volt 250 aH battery. After some online searching it seems as if golf cart battery chargers are your best bet. Example: https://www.batterystuff.com/battery-chargers/24-volt/10-20amps/eagle-performance-series-charger-i2420.html If ...

Re: OT: Building in isolated location

In peripheral nerves (a nerve which is not in the brain or spinal column) the regeneration of the axon occurs at about 1mm per day or 1” per month. I’m a dentist not a neurologist so take this with a grain of salt. It’s also been 30 years since I last studied this and new info has been developed sin...

Re: Amazing machine work

Wow! That is absolutely beautiful. The highly polished Aluminum speaks to an incredible to effort to achieve and even more to maintain. What was the original octane rating during WWII for the fuel required in a Packard Merlin? Are there any limitations on the engine while burning 100LL?

Warped cast iron

I have a a cast iron piece which is a transverse equalizer bar. It will be machined flat to 0.25" thick. However, it is warped and if machined in the current state will be too thin in the middle. The metal I believe is cast iron and when I draw a file across it the file barley scratches the metal. I...

Re: Amazing machine work

Glenn, How many hours do the engines accrue before overhaul? What determines when overhaul is necessary? Also what parts typically require replacement or refurbishment. My aircraft engine is a 6 cylinder horizontally opposed air cooled apparatus and I’m well familiar with its potential failure modes...

Re: Spinning bearings with

My aircraft mechanic friend is zealous about air and spinning a bearing. He claims that it doesn’t take much movement with a dry bearing to cause damage. After cleaning in solvent they will blow the bearing out but restrict any moment in the bearing. He said that is standard practice in the aircraft...

"Mounting a square piece between centers

OK, I have to mount a 1/2" square shaft 6" long in the lathe between centers. 1) Assuming one starts with a 4 jaw chuck how does one center a square piece in the 4 jaw chuck especially one that is only 1/2"? 2) Most of the shaft is to be turned down to 1/4" round except for one end which will be lef...

Re: Softjaw question

Since I have no machining experience or anywhere locally to gain experience, this board has become my apprenticeship. It's awesome to have ...
