RMweb Premium airnimal Posted February 2, 2021 Author RMweb Premium Share Posted February 2, 2021 (edited) First side done. I have soldered the brake shoes to the W-irons so that it all comes apart for painting but I haven't soldered the cross shaft in yet. The brake push rods are just folded over at the tumbler end and will be glue up solid after painting. Just the other side to do now before I start on interesting bit making the outside guards handle and connecting brackets. Now it is in you will not be able to see much of it with the footboards on.

Painting the rubbing faces of the blocks should sort it. Link to post Share on other sites More sharing options...
RMweb Premium airnimal Posted February 3, 2021 Author RMweb Premium Share Posted February 3, 2021 Guy, I think there is enough clearance even with the amount of up and down movement for me not to worry about shorts. I have used this method before and I havn't had any trouble. I have decided to solder up all one side of the brakegear and cut the brake shaft in half because trying to wiggle this in with the tumblers both side was beginning to get a little tricky. I will put a bit of tube over the brake shaft to join them together later. 11 1 Link to post Share on other sites More sharing options...
RMweb Premium airnimal Posted February 3, 2021 Author RMweb Premium Share Posted February 3, 2021 Here is a photograph of them seperated. This will make them so much easier to spray paint them. One of my pet hates is trying to paint in tiny crevices and behind wheels. 14 3 Link to post Share on other sites More sharing options...
RMweb Premium airnimal Posted February 3, 2021 Author RMweb Premium Share Posted February 3, 2021 I am pleased that this method has worked well and I have a free running underframe that all comes apart for easy painting. I am going to make a bracket that also will be mounted on one of the W-irons to support the crank arm from the brake standard. I think this is a job for tomorrow because we have had 2 of our young grandsons here today. They are 18 months and 3 years old with enough energy to run rings around me and my wife, they never stop. Both mum and dad are teachers so we have them every Wednesday as they are in our bubble. 6 6 Link to post Share on other sites More sharing options...

RMweb Premium airnimal Posted February 4, 2021 Author RMweb Premium Share Posted February 4, 2021 I have started on the brake handle and linkages. The handle is a length of .95mm brass tube with a 14 BA screw soldered in. The part that it screws into was made from 1.5mm square brass bar. I drilled and tapped it 14 BA before cutting a small section with a piecing saw. 6 5 Link to post Share on other sites More sharing options...
RMweb Premium airnimal Posted February 4, 2021 Author RMweb Premium Share Posted February 4, 2021 The sidetfames have been made and soldered to the brake shaft. Onwards to the L shaped operating bottom brackets before I make the handle and mounting plates. 9 4 Link to post Share on other sites More sharing options...
RMweb Premium Popular Post airnimal Posted February 4, 2021 Author RMweb Premium Popular Post Share Posted February 4, 2021 The bracket holding the brake shaft to the body has been made from a bit of tube and nickel strip. I cut the tube to size after soldering it to the strip and drilling for the Masterclub bolts. 9 1 11 Link to post Share on other sites More sharing options...
RMweb Premium Popular Post airnimal Posted February 4, 2021 Author RMweb Premium Popular Post Share Posted February 4, 2021 Still to make yet is the L shaped brackets underneath but I done the moving T handle. I am not going to solder this in so that I can move it to any position. 8 16 Link to post Share on other sites More sharing options...
Adam88 Posted February 4, 2021 Share Posted February 4, 2021 These models remind me of Norman Dale's EM models which had working hand brakes. At the Manchester show he used to park them on a short length of sloping track to show they really worked. To be fair, I think he only made a few just to prove that it could be done and thereafter sense prevailed. 4 Link to post Share on other sites More sharing options...
Mol_PMB Posted February 4, 2021 Share Posted February 4, 2021 I was also secretly hoping the handbrake would work! But the important thing is that it looks like it does. And it looks absolutely wonderful. When are we going to be able to buy little DCC humans that can wind on the brakes? 1 2 Link to post Share on other sites More sharing options...

A small motor could be activated via a small DCC decoder to wind the brakes on and off, and a figure could be mounted with suitable joints to appear to be doing the winding, but without some complex farting about with servos, etc, the figure would have to remain attached to the handle. Not a problem if the brake handle is inside the van, though! Link to post Share on other sites More sharing options...
RMweb Premium Popular Post airnimal Posted February 4, 2021 Author RMweb Premium Popular Post Share Posted February 4, 2021 Adam88, I remember Norman's Dale models at the Manchester exhibition, I have been to everyone for 60 years. I am sorry that there will not be any working brakes or moving brakesman. Even if I could I'm quite happy with what I've made. The L conecting brackets have finally been made. I soldered 2 pieces of nickel together and drilled the holes before cutting them out with a piecing saw. I have to work out if these brackets go inside of the handle frames or outside. The 4 drawings in the wagon book have 2 of each so which is the right way ? 15 6 1 Link to post Share on other sites More sharing options...
RMweb Premium Popular Post airnimal Posted February 5, 2021 Author RMweb Premium Popular Post Share Posted February 5, 2021 I have had to make a new pair of L shaped brackets because the first pair were not long enough. I finally finished all the brakegear and connecting pull rod. So it's back to making the lamp irons and completing the rest of the body details. 15 14 2 Link to post Share on other sites More sharing options...

RMweb Premium airnimal Posted February 6, 2021 Author RMweb Premium Share Posted February 6, 2021 I have cut the windows out of a CD case just to see how they will look. Close up work always looks worst than it is in real life. I am sure real glass would be better but everytime I try and cut microscope slides I nearly always end up breaking them. 17 Link to post Share on other sites More sharing options...
Mol_PMB Posted February 7, 2021 Share Posted February 7, 2021 Are you using microscope slides or cover-slips (the very thin small squares)? I find that cover-slips can be scored (as long as they are on a hard surface) and then snapped along the score line. Yes, there is a failure rate but it’s less than 50% and I have a big box of them. I could try doing a few for the size you need, if you like? 2 Link to post Share on other sites More sharing options...
Chrisbr Posted February 7, 2021 Share Posted February 7, 2021 Mike, Get a tungsten carbide scriber (I have this one) and it's really easy to cut cover slips accurately with little waste Chris 2 1 1 Link to post Share on other sites More sharing options...
