Hi Everybody
Any opinions as to whether anti-surge baffles are worthwhile in the sidetanks?

Hi Ron,
I've never come across a design that uses them. I would think in our sizes they are probably not necessary due to the relatively small volumes of water involved ?

Hi John
I'm using roundhead rivets to make up the tank and the sides look a bit bare with just a row of rivets round the edge so I was going to do a couple of rivet runs vertically about a third and two thirds of the way along the side and thought I may as well use them to fit baffles while I was at it, but if it's not necessary I'll just put in dummy rivets.
Cheers,
Ron
PS What do you think of fitting the emergency hand pump somewhere other than inside the tank, ie in the cab or the driving truck? it seems a bit permanent in the tank if there's any problems with it in the future.

Gone crazy with brass cutting with your new bandsaw?  I think John is right - for all you can get in a side tank on a Simplex - unless you're doing rollercoasters, not worth the hassle. Plod PS - Fix the hand pump with bolts soldered to the base of the pump and a gasket underneath, then you can take it out any time you want. PPS - I'll count your rivets if you post a pic! |

Hi Ron,
they are certainly useful onboard ships, & are usually known as wash plates, if my memory serves me. It may be useful to fit them onto the tank covers, projecting downwards if that is practical. Locos don't move quite as much as ships, but they could be useful mounted across the tank, from left to right. They would break up the water surface to prevent surges, but it does seem like a lot of extra work,
regards,
George

PcPlod I'll post a pic when I've finished the first side, then you can count the rivets and let me know how many I need for the second side  Ron ;D |

Hi Ron, WHEN I get started on Simplex, my thoughts are to put the hand pump in the cab somewhere, possibly in an enlarged rear bunker, as I did for Helen. I'm not keen on putting them in the side tanks due to the necessity to make all, or part, of the tank top removable to get at them if (When!) they go wrong. That usually involves exposed screw heads to hold the top on, which, to my mind, usually look pretty dreadful on such a prominent feature. Another possibility is under the cab floor with the operating lever poking through a slot in the floor. I haven't thought about the solution yet though as painting Helen seems to be taking a lot longer than I expected it to, plus I'm spending a lot of time in the garden at the moment  John (just back from sunny Rugby after a super run with half painted Helen. 3 miles non stop and running very nicely ;D ) |

Haven't had much experience of soldering platework, I'm going to make a small test piece and see how I get on sealing it, if it isn't successful or it's untidy I'll seal them with petrol tank sealer.

That's a good point about getting to filters etc and I agree it would be better and neater if the whole top can be taken off for cleaning etc. I always use filtered rain water rather than tap water so I don't get much scale etc building up inside the tanks. Hopefully they won't need cleaning out very often.

Why not make the filter screw in from the bottom - then you can easily clean it (them?)
