Thread: Dehumidifiers
12/01/2016 15:33:39

Have a look at the Meaco website - plenty of info on humidifier types and appropriate applications.

I have a Meaco DD8L Junior running in a (poorly insulated) double garage with two (occasionally wet) cars, no significant problem with rust.

These are dessicant dehumidifiers (no volatile refrigerant or compressor). They are light, run fairly quietly (depends on fan speed), with a 4 stage humidistat, and work down to low temperatures. One side effect is that they emit warm, dry air. On the down side they have a small drainage tank considering the efficiency with which they extract water (about 20 litres/week on the medium setting in my garage), although they can be set up for continuous drainage (I use a 25l external tank).

Meaco have an online ordering system (other vendors are available) and a good delivery service (just a satisfied customer).

Hope this helps.

Gun oil or air tool oil might be possibilities.

I have not purchased from them but looks useful.

Also try looking at a thread entitled  'Raw Material Storage Methods'

Thread: MEW-169 Tool-post Grinder Article

Possibly a silly comment but I would have thought with the relative speeds involved it would not make a great deal of difference whether the grinder was rotating in the 'wrong' direction or not.
 
Also grinding from the front the dust would be directed mostly downwards.
 
However, I've absolutely no experience with grinding in the lathe.

Thread: Raw Material Storage Methods?
12/09/2010 21:01:04
I have used 65mm square section plastic downpipe (available in white,brown and black) stacked both horizontally and verically in two columns (one for round section and tubes, the other for square/rectangular section etc).
 
This is arranged so that the verical sections form the rear end of the horizontal and the horizontal sections form the floor of the veritical sections. In my case it's all stuck together with hot melt glue but upvc solvent glue would work.
 
The way the sections are arranged gives storage for lengths from about 24" down to approx 6".
 
I would take a photo but everything is tucked away between benches / cabinets.

Thread: Need for recomandations on cut off or parting tool
11/07/2010 21:07:36
I can recommend the Q-cut, speaking as a relative beginner.
 
I have recently performed several parting off operations (on a Warco WM240) on 35mm CI bar with no problems whatsoever (front toolpost).
 
I'm almost tempted to say it cuts cast iron like butter.
 
No problems with mild steel either.
 
Gives a very clean surface on the part remaining in the lathe.

My thanks to everyone for this informative thread - I shall get grinding!

My thanks to you both, Gordon for being braver than me asking the question and Terry for some very useful advice.
 
Terry - any chance of a close up side view to demonstrate any relief on the tool? (you see I really am a beginner - perpetual I'm afraid).
 
On another note:
 
I have found that the Diamond Tool holder (from an Australian company featured on this website) has been a revelation for me. Until I acquired it I was dependant on carbide tipped / replaceable tip lathe tools. Even I can grind a useable cutting edge on it and it appears to cut really well, easy to set up in the lathe (no shims required). This tool is now available in the UK, I believe, saving a fortune on postage and customs duty.

Further to my last post try:
 
for information on using stepper motors for electricity generation.

Sorry to arrive late.
 
Try looking in the direction of wind generator alternators - work well at 300 - 600 rpm.
 
Several designs on the internet - would need modifying / scaling down eg.
 
 
 
Stepper motors do work but produce relatively low frequency output and are prone to 'cogging' (try spinning one on load).
