Chucks for the WW lathe

You can never have too many chucks so I have made several over the past year. These include:

A dog driving center chuck with a brass counter balance

The brass counter balance is riveted in place and then turned flush. You can see the rivets on the back side. The center point is removable and employs a standard taper so that I can swap in male and female centers.

The drive leg is adjustable in and out from the center (and boy has that come in handy). This is beefier than the typical Watchmakers lathe dog chuck as I'm not making watch parts and need the greater strength for steel parts and parts of great diameter. It works beautifully and I like the marriage of brass and steel.

kk I found a set of split leg lathe dogs of the right sizes on eBay for a very reasonable price (largest is show in photo). These too look really terrific and are the right solution for the chuck.

3 inch diameter clamping face plate for oddly shaped parts.

The tiny clamping fingers were designed in CAD and printed in metal through shape ways. They work so very well and the cost was quite low. I can print more any time I need them.

Drill chuck centering collet

I purchased a nice little jacobs chuck for use in the WW lathe as well as an adapter collet from a chinese supplier. The chuck was fine but the collet was badly made having both radial inconsistencies as well as angular deviation. This rendered the drill chuck unusable when mounted. 

I decided to make a custom adjustable mount that I could carefully mount and center the chuck with. This worked so well, I'm making a full set for all the other chucks. The threaded adapter is a separate part and the collet has slightly oversized holes in it for adjustment. I lightly attach the two together and carefully tap the chuck into perfect alignment (testing it with my dial indicator as I go). Once it's right on, I remove the collet holding the chuck and really cinch the cap screws down.

Back onto the lathe it goes for a concentric dressing cut and it looks good and has tremendous accuracy now.

Indexing tool for watchmakers lathe

Hello friends
Today I completed the indexing tool for the watchmakers lathe. I've had on my wish list making some very fine rope knurl wheels and in order to do this I needed to be able to very accurately index the chuck. Having recently completed the new stands for the lathe with the accessory mounting t-slots, it seemed a perfect opportunity to design the indexing set up around just that. Below are the results

I had used the indexing pin and holes that come stock on the back of the headstock phenolic pulley. It's very hard to get light into there to insure a visual confirmation of inserting the pin into the right hole. I designed this new unit to put the pin on the back of the indexing plate and I put the pin support arm out far enough for good light and good visual line of sight.

I designed and 3D modeled the mounting tabs that use a 1/4-20 bolt to slide into the T-slots. You can see the mounting here.

I also developed the indexing pin as a spring loaded assembly. The insid…

Step #1: Imagining the WW lathe Steady rest

After weeks of creating temporary solutions for holding longer pieces of stock and after an equal number of weeks searching online for a micro-adjustable steady rest (ebay included), I came to the conclusion that the vast majority of what was available for my beautiful little WW lathe were steady rests with much more basic functionality. Additionally, the vintage steady rests were regularly selling for astronomical numbers on Ebay. I resolved to design exactly what I wanted and make it! (Below is the completed result of what began as this wish to have something better than what was available). It is now working so well, I decided to do more than post the fun of making it. I'll be offering the main parts as a kit for anyone who is interested and I'll do my best in this blog to detail all the specific process insights I learned while making this wonderful tool .

Step #2: Designing and Modeling the Steady Rest

I have a lot of experience in going from concept to prototype as I am inventor with an industrial design degree and am fully trained in drafting and modeling my designs in a 3D program, and have had many of them rapid prototyped using today's cutting edge services available online.
I had also been experimenting with making parts from bronze infused stainless steel from shapeways rapid prototyping service and had been extremely impressed with how detailed, dimensionally accurate and functionally strong the parts made from this material and process were.

Diving in, I developed a micro-adjuster system that was low profile and could be adjusted with finger pressure yet lock down rock solid once dialed in. I also wanted the steady rest to pivot open like on the big boy lathes for the ability to perform multiple machining operations on a part and replace it into the lathe with extreme accuracy. It's also great for multiple parts in small runs.

It was also important to me to make th…
