About Time There’s a Sherline & Taig Headstock Alternative
by Jeff Harrison
From hobby guys to watchmakers, everybody in mini machining knows Sherline and Taig. While they are good little machines, there are always those things that bothered me. For one, why can’t we get different collet sizes? Take a look at the Sherline lathe. You can get MT1, ER16 or 3C with a tiny through-hole in the spindle. For the really small stuff, that’s fine. Or even the WW collet system for very tiny stock. But, if you have anything bigger than the ER16 or 3C will handle, then you’re out of luck. Not that long ago I came across a company called GlockCNC.com. I say I came across it, but it was actually recommended by a watchmaker I know. He loves their products. Anyway, they offer ER25 up to ER50 collet size spindles. The smart thing they did was change the headstock and bearings too. Frankly, the bearings in the Sherline and Taig, mill or lathe, are pretty wimpy compared to the GlockCNC bearings. After all, if you’re looking to chuck bigger parts and use a bigger spindle arbor, you need bigger bearings. Here’s the thing though, not only did they have the foresight to use bigger bearings, but also offer better bearings.
The stock bearings for Taig or Sherline are probably ABEC1 or at best, ABEC3. GlockCNC uses ABEC5 deep groove bearings as a standard. They offer ABEC7 and even the crazy precise ABEC9. Both can be had in deep groove or angular contact. Personally, I prefer angular contact. It’s what you get in any super precision spindles that operate in commercial settings. Here is why I like the use of biggering bearings with higher accuracy. When you apply a load to bearings, it will deform the balls to some degree. If you’re going to use a more meaty spindle, you will have more rotating mass. Plus rotating mass of the cutter for a mill or stock for a lathe. The tiny bearings with tiny balls in them will deform to a greater degree than bearings with larger balls. This means under load, you can achieve better accuracy.
Obviously, these bigger bearings require a larger headstock. Which these guys have made and made it well. Take a look at the side flanges for mounting. The off a ton more rigidity than the Sherline mounting pin. For the Taig, it does require an adapter plate, which initially I didn’t like the idea. But then I watched a video about it. It’s actually quite smart. You see, the Taig mill uses a dovetail system and it’s pretty weak looking. The GlockCNC adapter will move the lateral loads to the entire Z axis carriage far far better than the stock dovetail system. So, it makes perfect sense.
There you have it…just a little take a much better Sherline and Taig through upgrades.

Now they we’ve spoken about shingle roofing systems, here is some information on metal roofing systems. Steel roofings can be an excellent choice for areas where there are high winds. They metal roofings can hold up against far greater mile per hour winds than regular shingle roofs. Metal roofing product weighs one seventh exactly what a shingle roofing weighs and put less tension on the structure. These roofs are fire evidence and have a lower insurance premium. If you have a brick home with a metal roofing, your possibilities of enduring a fire are extremely high.

There are lots of low end shingles such as plain or flat shingles. Some people may want to invest a bit more and get a slightly more pricey shingle, one that integrates a three dimensional look which is more appealing. One manufacturer calls this the “shadow”. These composition shingles have more of a sturdy appearance, reminiscent of the cedar shake shingles of old. Shingle roofings are susceptible to algae development. This is a stain-looking light streak which is seen on many roofings today. They can likewise include an anti-algae coating, nevertheless are more pricey however deserve every penny if curb appeal is a problem for you.
The most popular roofing system right now is a shingle roofing system this is due to the economy and all of the options offered. Now they we’ve talked about shingle roofs, here is some information on metal roofing systems. They metal roofs can withstand far greater mile per hour winds than routine shingle roofing systems. Metal roofing systems normally cost more, in the long run it is actually more affordable because metal roofings do last a very long time. You can likewise discover metal roofs to look like traditional shingles or cedar shake shingles these being ideal for all steel structures.
When installing a new roofing system or existing roofing, you have to consider metal roofings or shingle roofing systems. Listed below you will discover the pros and cons of both of these building products.

I’ve decided to start listing some heavy machinery photos. Most of them will be of industrial manufacturing, such as metal stamping presses, plastic injection machines, forklifts, die handlers and related equipment. Much of it will be larger stuff. For some reason I really like the heavy duty big machines and equipment. Even the railway and ocean going equipment is pretty good to photography. Old warehouses and factories are some of my other favorites to capture.
Heavy lifts with hydraulic gantry cranes, overhead bridge cranes, mobile cranes and track types are pretty interesting as well (maybe even throw in a few photo’s of lifts gone bad, those are always interesting). It seems that the manufacturing industry is on it’s way up. From what companies are telling me, orders are up and they are buying machines. Of course, there are a handful owners that have said they are slow, but not many. It looks like the tough thing for them to now find is used machinery for sale. So much of it was scraped during the last several years, that its made them hard to come by. Especially large stamping presses. With the price of scrap steel so high at the time, many were destroyed. The funny thing is, those same machines are worth huge dollars now.
