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: Holding screw-end end-mills/slot-drills|
I always take the ER chuck out of the mill and hold it in a bench vice to tighten. And as noted earlier, use an extension on the spanner to apply enough torque to tighten.
|Thread: Muncaster's Simple Entablature Engine|
The bottom photo shows the job supported at the tailstock by your live centre (I assume in the offset position) but the headstock end in a collet instead of a centre. Did the work piece just flex as it was rotated ?
|Thread: Aldi Metal Bandsaw|
Even on a hand saw, either metal or wod, a biit of wax on the blade makes cutting so much easier.
Lubricating Bandsaw Blades
My bandsaw (not Aldi) also has rubber on the drive wheels and I use bees wax to lubricate the blade which helps cutting and extends the life of the blade. The wax stick which I use is about 60mm dia x 300mm long and was purchased from a supplier of the blades. I run the blade thru the end of the wax stick prior to cutting. The saw is 5 years old and has done heaps of work. The rubber tyre is still good and has not broken down.
I would advise that you use bi-metal blades on your saw. They cost a bit more but last longer.
|Thread: Rake angle on Cutting Tools.....memory tips???|
As the years pass by, I find it harder and harder to remember things but a text book or computer helps me remember things like rake angles.
John, They should shut off completely. But there are some cheap clones about. Good luck making a repair.
|Thread: Using the Maplin (Dremel clone) for cutting tool steel|
If you are referring to a 1/4" lathe tool blank in a hardened state, it can be cut with an angle grinder (or Dremel) with a thin cut-off grinding disc. Tool steel is a general term for carbon steel that can be used for making tools, etc (eg. silver steel, + ) and is normally supplied in a soft, annealed state and can be easily machined prior to hardening.

Use the oilers that are used on steam engines. These are fitted with a shut-off valve and have an adjustable oil feed rate. The small glass window in the base is used to observe the rate at which the oil drips thru the oiler.
Available with 1/8" and 1/4" BSP thread.

|Thread: valve gear simulators|
This is a link to DON ASHTON'S STEAM LOCOMOTIVE VALVE GEARS.
which has links to simulators including one on Excel format. You will need a program that reads MS Excel files.
I'm not a Mac user but can't a Mack simulate a PC and run PC programs, even at a reduced efficiency ?
I don't know of a Stephenson's simulator for a computer but modelled my engine in 3D CAD and can manipulate the model to check any scenario. I can raise/lower the Stephenson's link, rotate the crankshaft to any angle and check slide valve position.
Welcome Hoss, from Sydney, Australia. Lots of helpful members on this site from all over the world.
|Thread: 3 phase motor|
You are replacing a 1 hp motor with one that is 3/4 hp, which as stated should be OK for anything except heavy cutting. But as you slow the motor speed down with the VFD, the power/torque of the motor will also reduce.
|Thread: Fusible plugs for model loco boilers|
Similar in Australia. Fusible plug body should not be less than 1/4" BSP.
Our code in Australia for model boilers over 4" diameter with a design pressure over 250kps (36psi) states that it should be fitted with a fusible plug. The plug should be filled with tin, not lead or solder as it has a lower melting point. A fusible plug is not only a safety feature to prevent a possible explosion but will help to prevent a costly repair in case the water gets too low.
|Thread: Traction Talk Forum|
I tried logging into TT earlier today and got the same warning message. Clicked onto the button to continue and could get in. There were no mention of a log in problem on the discussion posts.
I use Mozilla Firefox as a browser and it has been prompting me to upgrade to the latest version but have been puttinig it off for a couple of weeks. Did the upgrade and found that I could get into TT without any warning message. Not sure if TT have fixed the problem or a coincidence, but it works as normal. (keeping my finger crossed for the future).
I was on TT earlier today and did not have a problem but lloks like something is wrong now. A similar thing happened earlier this year.
|Thread: piston rings|
Is there a misprint in the original question for "a 1/2 size barn engine". Should it have been a beam engine instead.
In which case it is a steam engine and not an IC engine. Rubber O-rings are used in model steam engines but I am not sure of suitable size and material.
|Thread: 2-4-6 block woes|
If you do not have an accurate square and have access to a lathe, you could make a cylindrical square
|Thread: Reaming - depth of cut|
I only have a standard set of drills and for 12mm reamer use a 11.5mm drill (20 thou = 0.508mm) which will produce a hole slightly bigger 11.5mm.
