I was reading the post about manual machines with ball screws to eliminate backlash and was slapped by a weird idea. Has anyone tried using Moglice or a similar product on a worn acme nut? I know...

Thanks guys for all your help. The amp is a Hartke model 7000. It is one of the old mosfet models. If I had to guess I'd say it's about 15 years old. It only has a tube preamp and is mostly solid...

I don't know what a cathode decoupling cap is so I'll just have to pray. I'm assuming it has something to do with that red hot tube so I'm wearing some safety gear in case something gets decoupled!

O.K. I read Al's post again 50wv does indeed = 50v.
They are all electrolytic type caps. Big difference in size though.

Thanks, Al_The_Man.
They have some capacitor type function in the audio preamp. I don't know what exactly. All I know is the amp is burning up preamp tubes and some of the caps look swollen. I am...

I am replacing some swollen caps on an old bass amplifier. I orderded the caps from 2 different places because the one ran out. The two batches I recieved look way different from each other. The...

I think you have unscrewed the ball screw from the ball nut. I have seen articles about how to reload a ball nut.

Looking at those sharp inside corners, I would say that piece is better cast.

I had the head on mine move on me once while I was pocketing in some pretty tough steel. I replaced the bolts and nuts that clamp the column with grade 8 fasteners. Then a thorough coat of grease on...

Thanks for your help. I am on the road alot with my band so I'll start with some of that stuff and work my way back to cnc. The first device I would like to run is a shure wireless mixer/transmitter...

Would using batteries in place of wall transformers on smaller devices also work without a regulator? Other than keeping the batteries charged, are there any other pitfalls when it comes to doing...

This is a cnc question as well as a general question so here goes. I was wondering what steps must be taken to get rid of power supplies and use d.c. directly from batteries on various electronic...

Is it possible to turn the workpiece or the spindle 90 degrees and use a keyseat cutter or a slitting saw? This would give you a larger dia cutter and many more teeth to do the work. I know this...

Thanks for all your replies. Where to get the power is not likely to be a problem considering what is available these days. My plan is to use Honda's cogenerating furnace and a large battery bank. I...

Wow, I just looked at the first post and realized this topic was from 2005.
Oh well maybe the info can help somebody.

I have an f1 and would be glad to help if I can.
There is a forum dedicated to the f1 over on yahoo groups.
I believe there is a copy of the manual in the files section.
There is also alot of good...

I'll post this here first, but it may move over to benchtop mills.

Dynosor, I don't know how much a yaris or corolla costs, but I will try to shed some light on your question. I'm assuming by break even you mean make up the difference between the price of the cars....

Mariss, I for one am boycotting the phrases "global warming" and "climate change" because they are broad and too far distant for most people to understand. If you can't see the consequences of...

The whole point of recycling the batteries is to keep the toxins out of the environment and the batteries will probably get to their destination by oil power. In case you have forgotten gasoline and...

Jhowelb, The electricity to charge the batteries in hybrid cars does come indirectly from oil, I won't argue that. The oil (gasoline) is used to get the car moving just like any other car. the prius...

I can appreciate what you are doing Mariss, I would never doubt the quality of your product or your responsibility to your employees. The kind of jobs your company keeps in the USA are priceless...

Wyld, To answer your questions. A Prius costs somwhere around $25,000 base for a new one. Alot cheaper than a Hummer last time I checked. My state no longer offers anything to anyone for buying a...

I think we should change the name of this forum to something like "environmental interests" or hopefully something way better. The words Global Warming have become politically incorrect. There is so...
