I had damp problems in my shed/workshop & I was getting some signs of rust on my machines so I installed a dehumidifier, this not only lifts the temp up a little and also cured the damp problem completely.

Often then grinding tools the Wheel gets glassed and will not cut if you clean to up with a carborunderum dresser or wheel dresser, there are different types about including diamonds, once this glazing has gone it wil cut ok

with your help this is the cutter, tool & results I got, I am pleased with the results.

Hi Greg, thats the type of tool I used first, and this gave an ok finish, this may have improved with altering speed & feed & this is what I would try first on Steel & cast iron. All in all the advice I have been given has been sound & useful. I am new to model engineering & still have a lot to...

I found a carbide tipped tool with a 1/4 shank & tried this, it looked a good finish but a little rough, so I ground a piece of 1/4 square cobalt toolsteel and put a big rad on it, this when used on my ally test piece gave me an almost a mirror finish, job sorted thanks all of you for the help...

Hi, I have just made the mini fly cutter from the plan posted by rake60 in 2007, I am pleased with the results & have found a piece of tool steel to fit, but I wonder if anyone can advise me on how to grind the tool please? Peter

Hi Romartin, I also have a prazimat & parts for them are hard to find, I managed to find a back plate for mine, so now have a 3 jaw, 4 jaw & face plate with back plates. I bought mine as I didn't feel confident enough to make my own as I am new to turning, I did turn the front to fit the...

Thank you all for the good feedback, & yes it dose run but & don't have a video clip sorry!

Hi All, this is my first attempt at a steam engine, I found some plans by searching for a simple steam engine & found this one that doesn't require any castings, there are a few faults & I can see the machining is not up to a lot of the standard I have seen on this site, but I have learned a lot...
