Delph - Caprotti set back


Dave Holt

658 views

A problem has been identified with the right hand side of the tender for my Caprotti Black 5. The whole kit is a Comet product and the tender sides for this part welded type are very thin and rather flimsy, due to being half etched to provide the rivet pattern. During assembly of the second (RH) side, I pressed a bit too firmly to hold it against the internal structure for soldering. The result was a rippled effect where the lines of the framework showed through. Considerable time was spent trying to rectify this by "panel beating",so to speak, and the result didn't look too bad in raw metal. I thought I could live with the remaining marks, especially as the loco is to be heavily weathered.
However, once the tender was painted with a gloss finish (to help seat the lining transfers), it looked absolutely awful.

It was obviously pointless proceeding with full painting and lining, as no amount of weathering could possibly hide that amount of damage. So, David Clarke has stripped the paint from that side and returned the tender to me for rectification. To be honest, once stripped back to bare brass, it didn't look nearly so bad but a replacement side is to be fitted anyway. I'm not sure if Comet can supply replacement sides, but I bought a whole tender body kit as the easiest option.
The original intention was to trim away the damaged side close to the bulkheads, fire iron tunnel and front piece and then file off any remaining raised rivet or beading detail. However, on closer inspection and the discovery that the side was not well attached is certain areas, I change tack and decided to try and remove the existing, damaged side entirely. This proved not too difficult although it got quite hot whilst unsoldering some of the joints and asbestos fingers would have been an advantage. Once the side was off, the underlying structure was filed flat and any remaining bobbles of solder removed. Here is the resulting tender body with the now totally destroyed side lying in front.

Since the photo was taken this lunch time, I've prepared the new replacement side and fixed the two hand rails, ready for reattachment. The new side will be glued to the body, possibly with a few solder tacks for added security of attachment. Hopefully, I'll get this done later in the week so it can go back for painting sooner rather than later. Oh well........

I sympathise Dave. I find that it's always more difficult unsoldering stuff than it is soldering them in the first place. Today while finishing off the brake gear on a Rumney Models Grampus chassis, I spotted that I had the brake assemblies on the wrong sides of the chassis. Now, I know I checked and double checked which way round they went so how did I end up getting it wrong when I soldered them in place. So off came the push rod safety loops which are rather delicate before I attacked the brake assemblies themselves. These were not so easy as each end had to be heated and pushed out of its locating slot before the could the heat could be applied again so that they could be lifted vertically. Thank goodness they are relatively robust! Anyway, all cleaned up and reassembled now.

Ouch that looks painful. You have done a good job removing the side though and I'm sure you'll make a good job with the replacement side.

Some tenders etc. did get bashed around a bit, but probably not quite like that.  Anyway you have already made good progress with the repairs and the decision (probably the right one) made.  Good luck with finishing it off.
