Hi all
This is a tool I made from a good quality pair of old adjustable mole grips
With addition of a 1/2 inch smooth steel bush welded on then split after.

Maybe its around in UK? Not seen here in Australia .

Was created after seeing a larger pipe version on WWW

Is bloody great for working with soft copper pipe that gets out of round.
Cost to me was free  ie old grips free bush I lathed up free and welding free by me

To get a machine shop to do it maybe 20 + bucks?
The best copper tool you will ever use in your life.

Have seen a plumber friend do similar with a shifting spanner closed up to 1'2 inch gap and spun around but this works way better.
Resurrects wobbly pipe to a degree and gets pipe round for sliding fittings etc over.
Plus is great to hold copper in awkward places for bending, thread locking up etc
Excellent for close tank work aroung HW cylinders..

In UK it may be common. Probably been made a million times in past .
Not rocket science, but just not available in shops here.

anyone else have a good tool ideas for working with
copper , sheetmatal around solar tanks etc?

I'm a toolmaker by trade and have done  mods for similar uses over years and have  accumulated
useful time saving tools in my kit over the years..

Basic tool ideas can be some of the most useful time savers from my experience..

Bdooly good idea mate,

Nice one! I haven't seen anything like it in the uk.
Here's a few tool ideas:

Sump Plug tool
I always seem to lose my sump plug tool when I drain my car oil, so usually make one up using a bench grinder. the best one I made was from a bicycle crank (very hard material) but I've made them out of all sorts of things including allen keys. Simply grind into a rough pentagon/hexagon or whatever shape the sump plug is.

Circle cutter
If you ever need to cut out circles of  soft material (in my case, I needed to cut out felt circles): Use s piece of copper pipe, or better still a pipe fitting of appropriate size. Again, using a bench grinder, taper the outer edge to the inner edge to create a sharp point. Cut felt by placing felt on a block of softwood. Hit die with hammer to cut circle. Repeat until blunt (not long, when using copper!). You would be better using steel, but the nice thing about copper, is that a variety of sizes are usually close to hand.

Rotating sanding drum for woodlathe.
Some oil filters are the same thread as the shaft on cheap woodlathes. So for a rotating sanding drum, simply find an oil filter of the correct thread, Glue ali oxide paper or similar to outer surface of oil filter
