Electronics solder was always 60/40 - not sure if 70/30 would be that much different  :scratch:
Anyways, I order one cheap 38 mm dia model.

Solder pot appeared today. Crusty chinesesium, but price was righ. Came with an australian? three prong cable and two prong adapter that does not fit into socket, neither to cable :lol: Some adpter.

Anyways, it feels like need to check inside before powering up, change the cable and check grounding/insulation resistance.

Second thing: Which solder for pot? No rosin for sure, but would auto body 30% Tin, 70% Lead bar stuff work?

So after an exhausting day the shed is finished except for refitting the glass in the windows - thank goodness  :thumbup:

I started by fitting a panel of oiled hardboard to the small panel next to the door - the objective being to stiffen up this end of the shed. The majority of this end is door so the whole structure tends to rack. But this panel is only 12" wide - just putting the shiplap on it wouldn't be stiff enough. So hardboard followed by shiplap on top. Seems to have worked  :ddb:

Then I needed to make the door. Frankly I've been putting this off - it's bigger than my woodworking bench so difficult to keep it flat. But it occurred to me - put the old door on the bench and use it as a template - simples  :ddb:

Having hung the door the sky started to darken, need to get it all creosoted before the rain starts and the new wood get wet. I cut some 3/4" corner trims, gave the end grain of the ship lap a good dose of Creosote, then fitted the trims and sprayed the outside of the shed. It then started raining - never mind I'm now inside spraying that !

I now just need to remount the various electrical fittings and put the glass back in the windows and I can then get on resurrecting the Portakabin  :thumbup:

Another one in the history books was a great show and attendees looked to be enjoying themselves for the weekend.

Re capital cost.  We just went through the process. For lights that are on 9-5 5 days a week, payback was 6 months.
Your numbers may vary this by a bit I suppose, but for us it worked out like this:

2000lm LED tube (there are many, many cheap, crap, low output tubes out there, avoid them) $20
Measured power saving per tube 30W
Price of electricity $0.38 / Kw hr

That's assuming that you do it all at once. if you wait for the old tubes to fail then your effective cost is a little less because you were going to buy a replacement tube anyway.
We went the whole hog and removed the ballast and starter from the lights to scavenge a few extra mW

We've backed this up with our energy monitoring system which shows us saving about (but just under) the amount we expected.

From the title, I thought you wanted a fluorescent handle on the starter :bow:

So where does Methyl Hydrate fall into the alcohols discussion? I've been mixing shellac with this for a few years now with success. It's available pretty much everywhere in Canada. Gotta keep our fishing huts warm in the winter ya know!  :thumbup:

You can color shellac pretty easily with a variety of different dyes that are commonly available. TransTint is one brand name that comes to mind, it can be bought in liquid form. I'm sure that I've also used powered dyes from Lee Valley in the past also. I think with the correct amount of dye to shellac to alcohol, it would make a durable layout fluid as the OP suggests.

Very good Andrew.  :thumbup:

Last time I changed mine I bit the bullet and bought electronic starters for them all.  I've not had to replace any yet.

 - pig ark sheets are not only too curved, but have insufficient reach - I have a couple here unused at the moment. No grain silos unfortunately - the nearest one has been converted into a letting holiday home  :clap:

Presumably stress cracks, but whether from original casting or the repeated heating and cooling in use I wouldn't want to say  :scratch:
