John,
 
Thank you for the tip re. Firefox WiseStamp, works great, very useful.
 
By the way John, my VMC table has no more oil holes in it - yet.

Thread: milling machine power feed

Hi Dougie, ( you sound as if you could be Scottish ?)
 
You will find an article on fitting a home made power feed to a mill like yours ( I think ) on the following link.

Good luck, enjoy.

Hi all,
 
I have just received ME 4369 in the post this morning, Monday, 11th January.
 
It is once again, for the second month running, nice to get the actual mag in my hand and enjoy it, before seeing it listed as a back issue on the web.
 
Thank you David and all the ME staff.

Thread: Workshop Heating

Hi Engineers,
 
Thank you to all who are responding to this chilling question now. I'm sure many of us are very interested in how others heat their workshops, keep the info coming.
 
Regards to all.

Hi Les,
 
that is exactly the type of specific answer I was after (not hoping for though) you are a gentleman and a genius.

Thank you.

Hi Engineers,
 
thank you to all who responded to my general enquiry, I didn't however receive any answers to the specific question asked.
 
I am well aware of the H2O produced when burning propane.
 
I am wondering about these "new" type of catalytic propane heaters which apparently do not burn (with a flame) the gas, but instead spray it onto a chunk of platinum which in turn makes the heat by a chemical reaction rather than burning a flame. Are they any better/worse or just the same at the H2O production.
 
Anybody out there with one of these cat heaters could comment please.
 
I don't want the bother of installing and using a pot belly stove and I can't connect to the house central heating system, my workshop is at the bottom of the garden. I have made a small study of caravan type balanced flue heaters, which would seem to be very suitable except that they are expensive to buy unless via the dreaded eBay and I think I should be a bit scared to buy a gas appliance second hand from an unknown seller.
 
Thanks again.

Hi engineers,
 
The ongoing discussion under another topic about silver soldering inside workshops and the production of rust etc., as a by-product of burning propane has prompted me to ask this question:-
 
I am of course very well aware that for every pound of propane burned in a "conventional" superser type gas heater, you get rivers of water produced, making these types of heaters more or less useless in our workshops.
 
Does anyone out there know if the newer type of propane catalytic heaters produce the same or less water in their operation?
 
Any comment from the chemists among us, or anyone using a cat heater would be gratefully received.
 
Regards and a Happy New Year to all from a perishing Scottish workshop.

Thread: Model Engineer 4366
07/12/2009 21:56:54
Hi all, and David,
Just call me old-fashioned; I like to sit with my feet up in front of the fire with a glass of decent malt in hand and leaf through the pages of Model Engineer, looking to forward to whatever might be on the next page.
 
I do agree that the digital back issues on the website are a great idea and a very valuable and convenient way of looking up previous issues etc., but I really think that back issues should be just that. Surely issue 4366 being available as a back issue for near enough the best part of a fortnight before the real thing drops through my letterbox is a bit wonky.
 
When issue 4366 arrived today, I experienced no great urge to open the silver bag and to enjoy reading the mag manually. It is now filed on top of the pile of it's predecessors, un-thumbed - seems a bit of a waste.
 
Might it not be an idea, in future, not to digitally publish an issue as a back number until the next newer one is paper-published. (and delivered)
 
Anyway enough of my moaning, I've been reading and enjoying ME since about 1974 and I look forward to every issue.
 
David, thank you very much for your hard work in recent months, you have made ME better than ever.
 
Best wishes to all.

Donald Mitchell

Hi all,
I just received my copy of 4366 in the post today, Monday 7th.
I was always of the opinion that one of the main reasons we subscribe to a mag is so that we receive it before it generally goes on sale in the shops, I saw it on sale in Smiths in Carlisle last Sunday (not yesterday, ... the Sunday before) what's going on?
I also don't think that I'm well suited being able to read the mag in the "back issues" section of the web site for almost two weeks before receiving the hard copy in the post.
Yours,
A bit miffed subscriber; quite a bit miffed actually.
