Just a quick note to say you were the talk of our model railway club this week concerning the mazak rot. I have a T9 and my motor was found to have this rot, on phoning Hornby and spoke to a guy called Matt who to his credit was absolutely 1st class and said he was totally aware of the situation and offered to fix it if I posted my loco to him or would send me the part free of charge.Congratulations Hornby, I cant thank you enough. 1st class service from a 1st class company.

Sam the tender can be repaired. I just fitted some hornby spoked wheels straight in. It's a bit tricky getting the pinpoint axles into the axle boxes but there are holes ready to accept them. This also means the pick ups can be put back too. The more common fault, especially with the super detail tender drive variant is for loco chassis rot. I managed to buy a chassis on eBay and replace. But be warned... although the "S####" part number is the same, the casting isn't. It took a lot of milling to get the body to sit right. This is same problem for loco drive too. What's more complete rebuild of the 9f is quite tricky. In fact if I had known how much trouble it would have caused me I wouldn't have bothered. Finally I just want to say that mazak pest affects ALL manufacturers, not just Hornby. One of the online forums has put together a while spreadsheet of models and their problems. Typically it affects batches, so as you say your T9 may have a bad motor mount, mine have all been fine. So the list online is specific to loco running number. Hope this all helps.

I did stuff like that back in my model railway days, but with a pocket knife and a bit of scrap wood! Alternatively, their non-rotting parts could be used to repair other locomotives, either for yourself, or your friends, or randos on ebay ;)

Hi Sam, yes, but probably not the Hornby loco you were expecting - it's in the range of (Hornby) Dinky Toys 1935 Silver Jubilee streamlined articulated set No16. Most of the pre-war trains - carriages and locos - the ones with the cut-out windows - suffer from Mazac rot. Very few still have all their couplings and wheels intact. They were still made post war, with garter blue A4 and teak coaches, and later still in BR Green, with "blood and custard" coaches. You don't often see a good silver and grey pre-war set. The Hornby Dublo pre-war clockwork locos (yes, 00 gauge clockwork) are also very difficult to find now in good condition. Thanks for your cheerful and interesting videos, which are always a treat to watch now we are still confined to our homes. Cheers, Peter T.

My experience with Mazak rot wasn't model railway related, but it is Mazak rot nonetheless. Last Christmas, I got a beautiful triang minic model of my favourite ship. It was lovely and I played with it every day and took it to every occasion. It all started when I picked it up last week and noticed pitting and cracks in the rear funnel. I had seen this video and told my dad. My new triang minic Queen Elizabeth comes this Monday.

I took it to my local model shop to see if it could be fixed and unfortunately it was dead.

And I had this issue with a Roco SBB C5/6 steam loco. They used zamac (or mazac) for the whole tender interior. It blocked all moving parts on this tender driven loco. Luckily there was a recall so I got the whole tender replaced FOC. And mine was actually second hand bought at a rallye... (good warranty conditions ;-) )

I've had a Mantua 4-6-2 locomotive that is absolutely riddled with the stuff, the whole body is a few big castings that have all got zinc pest and it has most of the bits dumped into its box. Believe it or not, the thing actually went back to the manufacturer's headquarters in New York and came back worse mechanically.

Morning Sam, I've had Mazak rot problems on the Hornby Rebuilt Merchant Navy. Got R2268 35027 Port Line out for a run and the front bogie wasn't spinning, was seized up completely. So I attempted to unscrew it and it just crumbled away... Fortunately though I have a spare dead Merchant Navy being gradually cannibalised for spares so was able to replace the front bogie and now Port Line runs good as new. Worryingly though I can see some cracks in another of my Merchants.

Some of the older MNs/BBs/WCs since about 2006 are a real pain especially when Hornby will currently not accept any loco over 10years old for repair, these are expensive items and shouldn’t happen even when stored carefully.

I had an even worse Mazak rot issue with my Hornby Gordon where after getting him out for the first time in over a decade the tender chassis was badly warped, but still usesable, untill I tried my luck to far. I've kept some of the disintergrated bits to use as freight/tuck ballast but the motor wires were beyond repair. However I was able to keep the same loco running by swapping the tender casing with my second 9F which had just had the loco's power wires snap forcing me to get a third. (Loco drive at last. Third time lucky!)

Mixing up a solution of isopropyl alcohol, acetic acid and citric acid, 8:1:1, applying it to the Mazak and then leaving for 15 minutes, before neutralising with sodium bicarbonate is a very good way of stopping Mazak dead in its tracks.

Outstanding vid. I had heard of this happening with a certain Hot Wheel car and certain old toys. I also have heard this could be a problem with certain Lionel Engines from the 40's-60's. Extremely informative. I just discovered some of my collectibles (not trains) recently had some shelf-life issues. VERY distressing considering what I paid for them......I know how you feel. I discovered it yesterday and I"m still damn upset....and I mean damn upset. Things could always be worse however.....

@dancalmpeaceful3903 3 жыл бұрын

@@SamsTrains - I think the warning is this - EVERY collector should know that there is a possibility (but often rare) that CERTAIN collectibles are subject to deterioration- regardless of how you take care of them. I think with newer trains (post 1980's - say this date to play it safe), there is very little fear....although Sam you showed us - VERY clearly - that it can happen even with trains/collectibles made in the 2000's. Your video is quite fascinating frankly. I say this....because I used to be in manufacturing...and you are right - there MUST absolutely be a high LEVEL of QUALITY control when casting is done. The trouble is - us collectors (and even the manufacturer) unfortunately DON'T find out until YEARS later that the material used to make the train....or ANY collectible for that matter....was faulty. I think overall, most of us have nothing to fear. (and as I said earlier, I think, it is a bit somewhat rare) ..but it is something to be aware of . What IS great is that in some cases...there ARE replacement parts. Lastly, I KNOW exactly (as I'm SURE MANY others do) how you feel about an old loco that you've had for years.l......and have thoroughly enjoyed....but now...start to fail. You alluded to this in your video...and I felt your "pain". No ONE wants to "lose" an "old friend"! (This is WHY I don't have pets...I get TOO damn attached..and my heart breaks when they pass!) I was ...well, upset myself....until I saw the damn thing run again after you replaced the faulty part. Hurray! It was great to see "her" running around the track "kicking ass" and "taking names" (this is an American saying by the way). The fact that you ACTUALLY could FIND a replacement part IS the sign of a good manufacturer. One last question though - have you ever seen something similar with ANY Bachmann stuff? I'm just a bit curious........ As I said..a VERY good video...about a serious topic. Ps- the image of the broken airplane broke my heart...but IT SAID a million words and made the point quite well....
