As a result, I've reverted to using the paper dry but with the part not being soldered chemically blackened. So far, so good. Dave. To save the mess of chemically blackening, I use a Sharpie or similar felt pen, quicker and wipes off afterwards. Mike. 5 Link to post Share on other sites More sharing options...

Popular Post Killybegs Posted March 8, 2021 Author Popular Post Share Posted March 8, 2021 Nothing done on 2822 over the weekend but today I have drilled out the hornblocks and fitted the handrail knobs for the csb's. One frame was marked up for the handrail knobs that will carry the csb's. The two frames were then aligned using top hat bearings in the outer wheel blanks before drilling out to ensure that they were identical. You can see hoe close they are to the pivot positions for the brake hangers which have not yet been drilled out. It was for this reason that I had to use long handrail knobs on the hornblocks to avoid a clash. 14 1 6 Link to post Share on other sites More sharing options...
Dave Holt Posted March 8, 2021 Share Posted March 8, 2021 John, That's the sort of forward planning I admire. Although I do try to do lats of planning, there have been occasions when I've rushed in and then regretted it - like chopping out the horn slots and then wishing I left them in to locate axle centres or, as you have, align the frames for drilling. I commend your more organised approach. Dave. 1 1 Link to post Share on other sites More sharing options...

Duncan. Posted March 12, 2021 Share Posted March 12, 2021 Hi john, Nice work. What do the red and yellow dots on the frame signify? Cheers Duncan Link to post Share on other sites More sharing options...
Dave Holt Posted March 12, 2021 Share Posted March 12, 2021 Duncan. There's also white and blue - so i suspect the colours help avoid mixing up axleboxes/wheel sets, in due course. I'm sure John will explain the real purpose. I'm intrigued by the little "ape-hanger" handlebars sticking up from the top edge of the frames - or, perhaps, stylised reindeer antlers? Dave.

Killybegs Posted March 13, 2021 Author Share Posted March 13, 2021 You are quite correct Dave re the colours. The handlebars have me puzzled too. I have checked photos and the GA's (admittedly for the later Collett version) and can't find anything. The oil boxes are mounted on the rectangular frames further back. The best way of finding out what they are for would be to cut them off as I would then find the answer the following day! 1 Link to post Share on other sites More sharing options...

RMweb Premium Siberian Snooper Posted March 14, 2021 RMweb Premium Share Posted March 14, 2021 Are the springs supplied with the kit or were the sourced from elsewhere? Link to post Share on other sites More sharing options...
Killybegs Posted March 14, 2021 Author Share Posted March 14, 2021 The springs are supplied with the kit and comprise 3 etched laminations. They are designed to be soldered in place. I have modified them slightly so that the legs on the retainer can be soldered to the rear of the centre etch. This just involved cutting off one end of the inner etch. 1 1 Link to post Share on other sites More sharing options...

WRONG!! I have had another look at the pics and drawings and they are nothing to do with the sanding gear! I think Simon was quite right, they do appear to be mountings for the oil boxes to the front drivers. Why they are a different shape to those for the middle drivers, I don't know. There are six oil boxes in the kit but no info to confirm where they go. Sorry for earlier misinformation and apologies to Simon. 1 1 Link to post Share on other sites More sharing options...
Simond Posted March 15, 2021 Share Posted March 15, 2021 John please don't apologise, I should have put a "?" after my comment, because I had not looked at the drawings, I have a recollection, no more than that! I shall go have a look at my references tonight. See if I can shed any light atb Simon Link to post Share on other sites More sharing options...

When you say oil boxes do you mean the oil lubrication which was /is around the axleboxes or the separate oil boxes on the running plate which have to be topped up daily?
