Here is a list of all the postings Paul Lousick has made in our forums. Click on a thread name to jump to the thread.
|Thread: Boring Head|
The minimum hole diameter is normally governed by the size of the boring cutter. Yor could possibley go smaller by making your own cutters. Also, the boring head can make much bigger holes by mounting the cutter in the side hole instead of the one at the base. They are very useful and worth the investment. Lots of useful videos on Youtube.
|Thread: Steam powered RC aircraft|
We do not hear much about steam powered aircraft for obvious reasons but I found this article which appeared in ME Vol 194, No 424 in 2005 and a Youtube video of its first flight.
|Thread: Making from castings or scratch build.|
Building from purchased castings is quicker but making something ftrom scratch is definitely more rewarding. It all depends on what you want to achieve. I am building a 6" scale traction engines and would have prefered to make my own patterns and make my own castings but that would be too much of a task. Its been a 7 year build so far.
Most of the accessories, lubricator, valves etc. have been build from scratch. This allows you to modify existing designs and give it a personal touch. It is also much cheaper than paying someone else for their work and definitely more rewarding.
|Thread: Another "what is it lathe"|
Thanks Neil, gives me a starting point to look for info.
Our club was given this lathe, much in need of some TLC and is missing a few parts. Does anyone know what it is and where I can find a user manual, drawings, etc.

|Thread: Why are CNC lathes more expensive than a CNC Mill|
Not sure, but CNC mills are more common than CNC lathes. The higher price could simply be because of production costs for smaller quantities.
|Thread: How badly do I need a surface plate?|
You can make your own surface plate for little cost and a lot of elbow grease useing the 3-plate method of lapping the plates. See link below. (other examples of this method on the web)
|Thread: one tiny boiler to run several tiny engines ?|
Running more that 1 little engine could be possibe but would depend on how little they are and what volume of steam they require. It is only a little boiler and I would be surprised if it could run 4 engines. An option would be to make a manifold with an isolation valve on each port. Small valves are available from steam model suppliers if you do not want to make your own. You could then run each engine in turn or possibly more. Worth a try.
|Thread: Accessing Digital Issues|
I use Firefox on Windows 7 and can access the MEW archives. It did prompt me to update Adobe Flash but I clicked on the "-" icon to not update and it opened in my old Flash.
I do not like the way Adobe prompts you every month or so to update their software and normally ignore the message. There are also scam programs that use Flase updates to install viruses on your computer so check first where the message originates.

|Thread: A few newbie questions, sorry|
I am not a Myford expert but if one of your oilers is always full could mean that you have very good oil seals or the port to the bearings is blocked. If it is blocked there would be no oil getting to the bearings.
|Thread: Barrier Cream|
Bought Gloves in a Bottle from Repco, (the car spare parts supplier). Should be one near you somewhere.

Let me know what you think of the product
My hands are in oil & grease, etc every day and I have to wash often which leaves my hands dry and cracked therefore use barrier creams and moisturisers. Our chemists in Oz sell a great moisturiser called "Tough Hands" and is advertised as used by brick layers and concrete workers. It is very thick, dries quickly and is not greasy. One of the best barrier creams which I have used is sold by Repco automotive and called "Gloves in a Bottle". Not cheap but you only need a few drops. Advertising blurb says you can even put your hand in acid after applying. Have not tried this, but great for everything else.
|Thread: Different ways of boring a hole|
An interesting definition of DRILL and BORE (a hole)
In machining we refer to boring as an operation to enlarge an existing hole on a lathe with a boring bar or on a mill with a boring head, and drilling as using a bit (twist drill, etc) to cut a new hole. But in early days we used a brace and bit to bore a hole. Not to enlarge a hole but to make it in the first place.
We bore a hole in the ground to to get underground water with a drill. A single operation where the hole is not enlarged with another cutter. (Then a pipe inserted in the hole to extract the water.) On an oil rig, a hole is drilled in a similar operation to get oil.
What is your experience with the definition,
|Thread: Aldi bargain laser level|
I only had a home builders certificate and had to comply with the council inspectors request, otherwise they would not approve the completion of our house. Sometimes you have to do as they say and keep quiet. Fortunately I knew of a surveyor who lived nearby who did the job at a fair price.
Yes, the laser is a cheap and nasty piece of equipment but if used to its level of precision (pardon the pun) can be useful. I have also used it to set the heights for the boundary fences. Better that a string line which sags in the middle. One of its main faults is that it is hard to see the laser dot in bright light. OK on a white background if shaded from the sun.
Its a laser pointer with a bubble level and not a precision instrument if you only rely on the bubble.
I used one to determine the levels for the storm water drainage piping around my house and because it was on fairly flat land, could only achieve a fall of 1 in 100. Prior to using the laser, I used a length of clear plastic tube, filled with water to mark datum points at several positions around my house and used these points as targets for aligning the laser. Then I could swing the laser between the datum points and measure the depth to the trench for the water pipe.
After the pipes were installed, a council building inspector told me it had to be checked by a certified surveyor. Luckily the cheap laser level and water filled tube did their job and the project was passed.
|Thread: Unsolicited email from SOLIDWORKS|
Solidworks is only one of the professional CAD packages and most of them only include training tutorials if you pay for a licenced copy. The standard version costs $3995 with an annual maintenance fee of $1295. If you find a cheap or free tutorial, it is probably a pirate copy.
When I first started using Solidworks as a design draftsman, I was sent on a 1 week training course to learn the basics and later for another week to master the advanced features. Luckily work paid for the course.
Solidworks is not the only industry standard software. Inventor has been on par with it, as well as CATIA, Microstation and more. I started with Autocad 2D then ProEngineer then Solidworks. The best choice of CAD software depend on what type of industry you are in. I worked in mechanical engineering design and Solidworks was the best choice at the time. Since I hace spent many years using it, it is my preference now because I know how to use it.

|Thread: Bleed valve|
The one on our Fowler TE is like a tee with built in needle valve. I could design my own, just asking if anyone has an existing design first.
We have bleed valves on the lubricator on some of our full size engines which I operate and find that it is convenient for checking pump operation without having to break the supply line. Plus its another feature to add to the model.
I have completed the manufacture of a lubricator for my traction engine and would like to add an in line bleed valve to the oil feed pipe. Very handy for removing air from and for checking if the pump is working.
Does anyone have a drawing to suit a 1/8" OD tube ?
