Re: Electro-magnetic chuck control

You need to get a small Variac to control the current into the chuck. Wire the Variac to the incoming line and connect the output to your 110 to 220V transformer. Then wire a bridge rectifier to the output of the transformer to convert the AC to DC for the chuck. It may even be possible to just use ...

Turn-Pro 7x10-1/2 swivel head bandsaw?

Hi I am thinking of getting one of these, Enco has them on sale. Enco 127-3200 Does anyone out there have one and can tell me how wide the unit is? Need to know the minimum door width it will go through for my storage location. Mainly just the chip tray width. The Enco web site is really lacking on ...

Re: shop lighting

For those thinking of using LED's, I would plan on using 25 to 50% more fixtures than the lumen calculations would indicate. There is a lot of "Locked Rotor Horse Power" calculations happening with LED's these days. For those who don't know there is no such thing as a white LED. LED's chips all outp...

Re: DIY high pressure air compressor (3000PSI and more)

Hi, I have an old Corneilus 3000PSi portable compressor that I would guess was built in the early 50's or just after WWII. It only puts out 1.5cuft per minute but runs like the day it was built. Can't seem to find a photo but on top is a 3400 RPM single phase motor with the shaft running vertical do...

Re: shop lighting

About 8 months back I updated the lighting in my 24 x 30 shop that has an 11' ceiling. Initially I wanted to use LED's at least for the bragging, but I just could not get them to pencil out. Even built a prototype 2'x2' troffer based on a CREE application note, an LSI industires commercial troffer I...

Re: The cost of stuff...

There is one other measure of affluence/poverty that no one seems to talk about. Its on par if not better than equating things to the hours of labor and that is the energy content of things. Every thing one does, makes, eats, sells, uses has an inherent energy content. A society that has access to a...

Re: Witness mark engraving

Hi, I built several of these guage parts, they all came out fairly nice. I ended up engraving before anodizing then we filled the line with a white wax marker. This was my first attempt at DIY anodizing, did a couple in red, this one in violet and anohter in gold. Found the pre anodizing finish to b...

Re: Making a home brew printed circuit board

Carbide bits are the way to go but they are very brittle, if you look at them wrong they snap. You need a good high speed drill press with minimal run out. Even then just a little movement holding down the board and the carbide bit it toast. My recommendation is to use a hand held tool and HSS bits....

Re: Looking for a Rolling Tool Cabinet

Speaking of tool boxes. Anyone ever replace the metal on metal drawer slides with something better. I have some Craftsman and a couple of Kennedy's that don't slide all that well. Possibly mill something from UHMD or Delrin.

Witness mark engraving

Hi, I need to build a small gauge from some aluminum that will be red anodized. The part is fairly small about 1.5" square and will have two inch long witness marks engraved on the sruface. I really want the witness marks to be visable and stand out against the red background. The question is, do I ...

Re: Today's Project - Logan 1875 Apron

I have 4 copper and 3 steel disks. The odd thing is the steel ones are fine except on one disk. One of the 3 anit rotation bumps is also corroded a little and half missing. Also the whorm wheel teeth are fairly corroded. My clutch stacks stack: Cu-Fe-Cu-Fe-Cu-Fe-Cu The strange thing, even though it ...

Re: Today's Project - Logan 1875 Apron

Very interesting, I am not the only one cleaning up a Logan apron, nice job. I been working on my Logan model 1955H apron for a couple of days now it was really bad with about an inch of grunge on the bottom of the case. Also looked like someone had filled it with grease. This is part of a total res...
