I hate to do this but with moving to SE AZ soon I have to rent a place for awhile. The landlord said I can put up a shed but I cannot pour a concrete floor or put up anything permanent. Would there...

i've been reading up on the Tormach and it seems like it will fit the bill for learning CNC. Looks like a nice way to have a machine to learn on and have around for some small production work later....

Has anyone been able to come up with a safe and reliable bar feeder for the CNC conversions. I looked at the one Haas has for the SL10 series and it doesn't appear to be more than a piece of pipe...

That last on looks nice. Too bad I can't read German anymore. Anyone have a translator?

I figure you all get asked this alot but I need to learn CNC. It seems all the machinist jobs have or are going to CNC. I downloaded the CNCsimulator software and I have been playing with it for...

Ok everyone I need the procedure for machining a single point thread. The last one I did was about 8 years ago and for the life of me I cannot remember how to do it. Even if you could point to a site...

Al,

Sorry I didn't mention it earlier, but I do have a pretty good understanding of basic electricity. I work off and on with a journeyman electrician for some extra cash. I used to tinker with...

Hey all,

I'm trying to understand the whole concept of electronics, but I am having some difficulty understanding some of it. Could anyone suggest some good books to teach myself some theary and...

I might just do that Al. I wanted to have AC capabilities but this is supposed to be a "on the cheap" project. I know anything that can be welded with AC can be welded with DC and DC has the...

I took a good look at the generator this morning and here is what I could find out. It is rated at 300 amps continuous duty at 28.5 volts DC. I also talked to my father-in-law who gave it to me and...

I need some help on how to convert 300 amps DC to AC current. I was given a 300 amp DC generator and would like to build a portable welder with both AC and DC welding capabilities. Any help would be...

I've never ran an EDM so I'm not sure how the wire EDM's work. I Think I understand from roysol's post now though. There has to be a hole in the material and the wire threaded through the hole and...

I read here that Die-sinker and wire EDM's work on the same principle. Has anyone thought of using a set-up using a MIG welder set-up? Maybe use the controls from the book available on the die sinker...

Yes steel must be protected from oxygen and can be quite difficult to cast due to the amount of heat needed to melt it. The ITC line of coatings only reflect heat back into the melt making the...

Here's a trick we used when I worked at a local foundry. Make your riser a little larger than normal and have a second person pour into the riser when it becomes about half to three-quarters full....

Most aluminum used in automotive applications is A356 which casts easy and also responses well to a T5 or T6 heat treatment process. A356 is an excellent material for casting.

Also on the...

I seem to recall reading somewhere that if you put a few small drops of distilled white vinegar on magnesium it will bubble furiously while aluminum will do nothing. I'll have to check to be sure.

JRoque,
Thanks for the info on the Miniark controllers. I looked at them before and didn't think to much of them. But they should be worth a shot.

ViperTX,
I actually do know quite a bit about...

I am in the process of building the Gingery series of lathes and would like to add a variable speed dc drive. However, I can't find one for a decent price, so can anyone tell me how to build one or...

sounds like something i would be interested in. if things don't work out for building them are you goin to put them up as shareware or just let it die? summer is about the time i am looking at for...

When one uses a gear reduction to increase torque, wouldn't you in essence also get a microstepping effect too? For example if one uses a 4:1 reduction the drive gear would have to move four times...

This is exactly what I am talking about. I am a certified all position welder. I know more about hydraulics than any one person should. I am able to look at a machine and figure out how to duplicate...

Actually, some of it can be blamed on our education system. Many stuedents are simply passed on to the next grade or level simply because the teachers don't want to deal with those who need a little...

check out this site www.backyardmetalcasting.com

he has alot of info on melting iron and has links to other sites with even more info. for melting stell they make a 3500 degree F refractory but it...

Don't get me wrong, formal education is a good thing if the person paying for it actually pays attention to what is going on. In my experience, however, in dealing with college educated people they...

I jope no one takes this personally, but I think college is overrated. I spent five years as a machinist and found many problems with the designs of mechanical parts designed by mechanical engineers...

thank you to you guys. i was reading up on some of the components and was having some confusion over the low and high frequqncy filter. the way it was explained in the text i was reading the...

I been looking around in a few text books and have not been able sort out some of the component explanations, so I have a few questions.

1. I know resistors resist the flow of electricity in...

I was also looking into this and found the following site www.eminebea.com/content/html/en/motor_list/pm_motor/index.shtml.

From what i have found the PM55L is the biggest PM motor used in the...

found this in mytravels: http://cscott.net/Projects/FabClass/final/edesign1.html

maybe the gurus here could take a look at this and enlighten us as to what type of power supply this is and whether...
