Adding inexpensive DRO to older equipment

If you decide to go with this brand, be sure to get the “EZ-VIEW” model. There are still a lot of their previous models available and they’re not nearly as functional and have much less capabilities. These really did change my world as far as milling and using the machine.

It was on eBay and the sellers handle is taylortoolworksllc.

If I remember correctly, I bought a 6” for Z (the quill) a 24” for X and a 12” for Y. As I said in another reply – you can cut the scales to any length you want. I welded up a “very” sturdy mount that had some rotation for perfect viewing.

WTF is a Franzinator?

Sometimes the most useful things have the oddest names. Take the Franzinator, for instance. Named after Franz©, its curmudgeonly inventor, the Franzinator is a device used to separate moisture from compressed air. Having moisture in compressed air is not a a good thing, especially in painting where it contaminates the painted surface, or in media blasting where it causes the media to clump and not work as well. As well as causing rust in the air tanks and air tools, moisture is best removed. A number of methods have been developed from expensive refrigerated driers used to pre-condition air before it gets to the compressor, to simple mechanical separators that sit in the air line between the tanks and the air tool. Here is a tank that uses a chemical desiccant to dry the air. There are also ways to install the air lines that are intended to either cause moisture to condense or collect before it is sent to the air tool. A non-mechanical separator causes the moisture in the hotte

A Heat Insulation Spray-on Coating Alternative to Lizard Skin.

One of the well-known spray-on heat-shield products is Lizard Skin. From their website, “LizardSkin Ceramic Insulation (CI) is an advanced spray on thermal coating that consists of a water-based composition of high-grade acrylic binders with ceramic insulation particles to create a thermal barrier.” The Material Safety Data Sheet (commonly referred to as the MSDS) can be found here . This sheet shows the composition of Lizard Skin as: 1 - Water 7732-18-5 40-50% 2 - Resin Polymer 00-00-00 20-30% 3 - Trade Secret Insulation Media 10-20% 4 - Carbon Black 1333-86-4 5-10% 5 - Extender Pigment 1317-65-3 1-5% It’s relatively expensive at $200 for two gallons. They sell a special gun ($120) to spray it on although it can be applied with a brush or roller. Substitutes It's possible to make your own for much less cost. 1 – High solids white latex ceiling paint. 2 - Acrylic Polymer Resin - increases paint flow and durability. One source is Acri-Flow

O-Ringing the Block and Heads for Higher Compression Engines HOWTO

I found some useful advice in this forum thread from user AK's REX. "To my understanding o-ringing the block or the head prove to be about equally effective. That said I would say it depends if you want to have receiver grooves machined. The most conventional method is to machine and o-ring the block, then machine receiver grooves opposite the o-rings in the heads. I guess it can probably be done in reverse fashion as well. As far as the receiver grooves are concerned, it not only helps in high compression and or boosted applications, but helps wet motors from losing fluid which is a common problem with copper head gaskets. It allows the o-ring to literally push the gasket into the receiver groove to provide a better seal. Speaking of copper gaskets here is a bit of info from SCE regarding this stuff; O-ring grooves may be cut in either the block or cylinder head. When using copper head gaskets thinner than .050, O-ring height should be no more than 25% of gasket thickness
