I don't know what your budget is but for this sort of thing I use roof batten from a roofing supplies company. The last lot I got was 2" x 1" x 3.6m @ 45p a metre and its already treated. I think the blue stuff is cheaper than the red. Smaller sections are available for even less.

My workshop is brick and timber 5m x 2.5m with no permanent heating.

I put 100mm of Celotex under the concrete floor and 70mm on the brick walls. The walls were then lined with 1/2" ply. The ceiling has loft type rollled insulation blanket from Wickes. I haven't worried at all about all the thermal bridging, vapour barriers and all the other stuff you hear.

It is a nice cool temp in the heat of summer and cold in winter (as it had no heating).

I bought a Firefly 2Kw 3 bar quartz electric outdoor patio heater and stuck it on the wall over the bench.

When I go into the workshop I get instant heat on me and in only a few minutes I am turning the bars down to just 1 and then it stays quite comfortable in there. I have tried 2kw fan heaters and I think they are useless as they take an age to feel any noticeable difference. If you get one or two of these quartz heaters you really will feel the benefit instantly.

I never had any damp problems but I now also run a small Ebac dehumidifier over the winter on a permanent drain and I have never had any damp, condensation rust or any problems at all.

I personally would not get a wood burner unless you are lucky enough to spend the day in there because of the time it will take to get going etc.

Hope this has been of some help.

Target Fixation at its best. "Dont hit the cherry picker, Dont hit the cherry picker, Damn"

I also love the round of applause at the end for being a total retard.

Regards Safety. If your worried someone might mess about with a a machine show them this sort of thing. Its not nasty in any way but does show well not to mess with machinery.

Last week I stepped into my sandals just to go and lock up my workshop. I couldn't help doing a few more cuts on my big Harrison lathe. I then did a very silly hot swarf between the toes dance, which is a bit like tap dancing but with more swearing.

Joe thanks for the info, that seems like really good advice which I will probably try. I'm not really sure why you would need a relay isolated from the mains to switch it on and off. What is wrong with just a normal foot switch, switching the power to the primary side? I'm sure as long as all the electrics on the mains side are safely concealed the only danger as far as I can see is getting burnt by the secondary side and not shocked as its an isolated transformer and only a couple of volts. or am I missing something?

Michael That is exactly the thing I had in mind. Gerald Wingrove emailed me this morning and told me he used a variable transformer on his but it has very recently died in a puff of smoke. So he is getting an American Beauty but they are very expensive.

Thanks

Hi

I already have a microwave transformer and have taken out the secondary winding.

I don't know what current I need so cant answer that one I'm afraid. I am guessing a power output of 200-300 Watts.

I wanted to do this after seeing the Gas Turbine Builders Association stand at the Warwick Model Engineering show. They had a spot welder on their stand that was being demonstrated welding stainless steel. It was made from a microwave transformer. It used a timer from Maplin to control the on/off time of the weld. I have the plans for this welder from the GTBA but i would like to use this to just heat brass for soldering and not welding. Hence my question about controlling the output so I dont melt my brass.

Thanks for your advice above

Thanks. When i used the search in the top right corner it looked to me as if nothing came up but I now see it does.

Hi

I want to make a resisitance soldering unit for building my tender bodywork and other projects. I was trying to do something similar to Gerald Wingrove as described in his book. I know about using an isolation transformer and don't stick your finger on the mains etc

The advice I was looking for is what is the best or simplest method to control the primary side of the transformer in order to vary the heating on the secondary side. I have just read an old article in MEW about a band saw welder but the control method is a bit sketchy.

I know some people may be a bit reluctant to give this sort of advice as there are a lot of plonkers out here but I am not really doing anything different than making an instant heat soldering iron but with a variable heat control.

Thanks for any help.

I am going to put on progressive rifling or gain twist. Thats one reason why I want the hole drilled to the end.

I will put a progressive spiral of rod around a larger rod and then pull this through a die to spin the cutter as it comes up the tube.

Thanks

Going back to your previous post, this would make a nice little model all by itself!

Its a 12.5 inch in Hurst Castle near Isle of Wight. Its got wood work lathe work, it would be great.

How do you chill iron
