Here is another one of my “Sneak Previews”. You can read the previous posts that hinted at this concept. The post before this showed where I was going.

You can see assembly is not complete but this reveals the complete design. The only part I had to make was the conversion mounting plate between the Taig lathe and the Taig mill table. The base plate of the mill is 3/8 thick and so is the adapter plate. A 3/4 inch 10-30 bolt works perfectly with the existing holes and doesn’t… Continue reading

Design Study

Hmm...

Hmm…

I have the design of my Taig CNC mill to CNC lathe conversion further along. I have the few scraps of the non-Taig material in hand and I placed an order for all new Taig components I will be using. I had an eight year old spindle and a 3,000 rpm Dayton motor but I decided to design with current parts and slower motor so there would be no surprises if I put together a kit. I also have a new idea for the tool mount that will be much easier and probably cheaper to implement.

The CNC lathe… Continue reading

Machining Job for Roboboat

I just ordered a couple (2) 6-18 Volt Johnson 9167AK electric motors for the Roboboat project. I do not yet know if they are suitable. I’ll discover that once I receive them. This is part of the problem when buying something you can’t first touch and feel. Especially if it something you have never owned in the past.

The specifications seem to be OK and the cost was very low (about $7.00 each on eBay) so I figured it was worth the risk. That is all part of the cost when creating a prototype. If anything the motor’s physical… Continue reading

…and a cast of thousands.


That’s a famous movie intro tag from when I was a kid. (Ben Hur, Moses and The Ten Commandments, etc.) In this case the “cast” is a bit different. No Charleston Heston. Yes, a pun.

The process here is casting pewter into a mold. Perhaps thousands could be made given enough time. What I find interesting is the use of a rubber mold. When I was much younger I remember toy soldiers cast in metal molds. (The metal ones are still available.)

The mold shown here looks like it was made with hot vulcanized rubber but hot… Continue reading

What Will It Cost Me?

I receive such requests from designers or just people with ideas, asking if I can make something complicated for them. Most of the time I say no, because I have enough projects of my own on which I would like to be working. There are also some designs that are beyond my means, usually because it is too large or requires special tooling and materials. (I wish I could charge the designer for the new tools!!)  Some of the designs also suffer from knowledge of how things are made on machine tools. The sketches and drawings show holes where they… Continue reading
