If you find a three phase equipment that suits your needs go ahead and just add a phase converter so you can plug a three phase equipment to a regular one phase power outlet. I've seen these gadgets in action and it is amazing the level of control you can achieve with them. They are not cheap...

The sticky material is polypropilene film with an adhesive covered side. It's usually sold at stationery stores, it's used to cover books and notebooks so they last longer. I'm not sure but I think that Home Depot may have a similar material.

The first picture shows my method to cut the ends of the paper strips with a 45° angle. The second picture shows the bellow's interior after folded. I covered this side with the same film, the paper strips are protected from moisture, oil, etc. If not protected this way the paper stripes will...

No long ago the bellows of my mini mill broke. I first though of ordering a new set but S&H charges are high, about 30.00 dollars for a small parcel sent to Mexico. Since I have previous experience making bellows for enlargers and other photographic equipment I decided to make my own bellows...

Congratulations for your sale. I must agree with Ian: it was really damn cheap. When I purchased my mini mill I had to pay almost USD 300.00 for shipping, taxes and import duties. It was cheaper than the same mill sold by Travers Mexico however, those guys put a USD 1,200.00 price tag, stand and...

Little Machine Shop sells a CNC mill for 5K. They usually invite potential customers to see the mill in action so they can have a good idea of the mill's performance, limits an so on. Sherline sells small CNC machines and I once saw a CNC conversion kit for a Proxxon mini mill that included...

Well, that's new and quite unusual. I worked at a jeweler's shop many years ago and I remember gold is a soft material that can be cut, hammered to shape with soft tools, it is a material very easy to work with. The engraving tools at the shop were not sharpened oftenly because of gold's...

I haven't calibrated this protractor so I'm not in the positition of making a statement about its accuracy but based only on its resolution I think this can be quite accurate since it has a Vernier scale with a 2 minute resolution. It may not have the accuracy of the sine bar but it's close and...

I purchased my mini mill at Micro Mark which is an upgraded Sieg machine with belt drive and a good spindle speed control. They carry both mill and lathe accesories fairly priced. You can consider their products as upgraded Sieg machines with quality according to price, of course they can't be...

Gus: I'm glad you enjoyed the mass in Mexican style, here in Puebla there's no reason to skip mass since there are 72 churches just in the old city. I don't currently work near the old downtown but it's hard to escape from God's ministers, I have two churches two blocks away from my office. At...

Zamak is zinc an alloy commonly used in the automotive industry, it's mostly zinc with Al and Cu as secondary components. The material has good mechanical characteristics but small variations in the casting process can produce a brittle material. Last year I had to make laboratory tests on...

One of the knobs in my protractor was badly bent so I used a small collet to straight it up and that was it. I also had to clean a lot of the protective grease. I also found a "how to" picture about the many measurements you can make with this particular instrument it turned out to be six or...

Good motto, I'm not a Latin expert myself but as a boy raised Catholic I had to know a bunch of Church's Latin mottos by hearth. I had a good laugh with your second line ... poor dog.

Thanks a lot for your advice, the mail order is a good idea. By the way Tin Falcon, what means your Latin motto? I know what the first sentence means but the second I can't get it.

My sister is going to visit some friends in Manassas VA by the end of this month, she also plans to go to Alexandria and Washihgton DC. She offered to bring back a few things I'd like to purchase at USA. I wonder if somebody knows about stores in that zone that carry supplies or kits for the...
