Somewhere I remember a chart floating around that gave the tolerances, if not stated otherwise, for dimensions in fractions, 1 decimal place, 2 decimal places etc. Has anyone seen it? Bob.

Not to take you too far off into the weeds but how much pressure does it take to push the hot rubber into the mould and what kind of connector are you using for the top of the plug? Bob

How about a little more info on how you make those great spark plug boots?

I know vinegar will slow down the set time of plaster, it may work on the drywall compound as well. Bob

What causes aging in the back lot to make them better? Is it the daily relatively small heat cycle day to night or is there some change simply due to age? I have some castings that must be great by now!

With any glass product run the lowest air pressure that accomplishes the job at hand. The higher the air pressure the more dust and the shorter the abrasive life. Crushed glass is cheap and leaves a perfect finish for painting or powder coating, IMHO. I run 3 cabinets with different abrasives. Bob

I love that Idea. Is there somewhere I can get a higher resolution image to get printed at Staples and put on the wall? Bob

Somewhere I saw a similar system that used rectangular gutter down spouts pop riveted together. Less wasted space between the sections and the rectangles can be rotated horizontal or vertical to fit your space better. Bob

peter195124, do you just crop in a photo program or process it in another way? I was thinking poster board from the office supply might be useful for a back drop but what color so as to not mess with the cameras settings. White, gray or something else? Bob

The Gorillapod is definetly going on my christmas list. Any way to get an iPhone to focus closer than the 10 or so inches away that mine seem to bottom out at? Bob

Thanks everyone. What I'm getting so far is use diffuse lighting, uncluttered surroundings, get a tripod or camera mount for the phone and take lots of shots. I've never posted a build but am thinking about it. I suppose you all can tell me what to do better as I go along. Bob

Are there any threads here with tips on taking photographs to post of your build? I am NOT good at taking pictures in general and only have an iPhone to work with. As a build thread is no good without pictures I need helping that department. Any threads or help? Bob

Most of us have a cutter diameter that is our go to for most work. Pick the pulleys that you would use for that cutter with a normal 3 phase feed. Your motor will run at that speed at 60Hz on the VFD. Vary it up and down from there but as others have said, you're not married to that pulley. You...

I had a deaf cat that wasn't scared of anything. He would sit on top of the lathe and swat at the chips as they flew off. He would also get into the deep dish of the tractor wheels and walk inside them like a hamster in a wheel as I drove around. I miss him. Bob
