Re: Resistance Soldering

I hope this will be forgiven as a bit of diversion, but are any of you users the proud possessor of a heart pacemaker? I have rebuilt my late father’s car battery charger into an RSU, quite successfully, but have since then had to have a pacemaker fitted, and have been warned by the technicians to a...

Re: Singles and suspension

In MRJ 21 page 55 Allan Sibley described how he arranged the drive for a GWR Dean single. The drive was on the trailing wheel via an intermediate shaft geared to the motor and the "driving" wheel was weighted and allowed to go along for the ride. This arrangement had the advantages of 1) ...

Re: Singles and suspension

Slight diversion - do you have a .pdf you could send me of the instructions of your now withdrawn carriage set couplings? Lost mine Mike You mean the cast brass ones? I don't think there were ever any instructions for them. You just bolted them on one coach and hoped for the best. I am working on s...

Re: Singles and suspension

Not done one myself, but faced with the design challenge, I would be tempted to look at driving all three tender axles via spur gears using an adapted diesel loco mechanism - there are planty of them out there. The biggest challenge would be hiding it from view within a pretty sparse tender underfr...

Re: Singles and suspension

I have all but ruled out CSBs, as a solitary driven axle doesn’t bode well with them... Why? I know that conventional wisdom on CSBs has suggested in the past that you need the centre of three axles slightly softer than the outer two to prevent porpoising (rocking around the centre axle) but experi...

Re: Singles and suspension

Can't see how hanging the tender on the back will help adhesion as it only increases weight on trailing axle. You'd need a strange cantilever to reach the centre. You want loco as heavy as poss so motor goes in tender with thin wire shaft across cab floor. Spring loco like full size with wire leaf ...

Re: Singles and suspension

Can I point you to Barry Luck's seminal articles in MRJs 18 & 19 on split frames wherein he described his solution to the traction problems in building, if memory serves, a Brighton G 2-2-2. As for the Chatham H I use twin beams on the drivers and have the bogie pivot as the third leg. The bogi...

Singles and suspension

I don’t quite know where there is any reference to Single driver locos in these threads, so I am posting one to ask. Is there anyone out there who has gone through the thorny issue of how to ‘suspend’ a 2-2-2? I am an LB&SCR modeller, and have to produce at least 3 2-2-2s. I have all but ruled o...

Re: Fine sanding

Why not glue wet and dry paper to Coffee shop wooden mixer sticks? They’re free, especially if you are recycling them after stirring your coffe! You can choose the grade needed. Then you can choose the shape by clipping the end with your Xurons to the shape you need. Always trim the wet-and-dry with...

Re: High Level Gearbox range - improvements

I know this is a bit late coming, as I have only just read the postings about the old style of High Level gearboxes - of which I have some myself - but can't a brass 1/8" adaptor with a screw in the side be used - from Branchlines or whoever it was that supplied them? Simply thread both on to a...
