JADIES AND LENTLEMEN. HEAR YE HEAR YE!
Pray gather round and hear the latest episode of the Great Deans Fittings Saga!
Herewith the promised (threatened🙄) report on the fittings, especially the running gear, of my Deans HMS Manxman kit. First the Deans blurb-
"Propshafts in stainless steel are cased in brass proptubes with fitted oilers and replaceable bearings along with rudder and tiller arm."
Props aren't mentioned, they didn't dare!
First two pics show why. Crudely cast, in what I choose to call 'muck metal'.
Even if you took the trouble to fettle them up and balance them, the blade shape is all wrong and if you tried to bend / hammer them into a decent pitch they'd most likely snap. Heating wouldn't help either, they'd melt😭 Sooo
Pair (left and right hand) Raboesch type 156 30mm on order. Cost; circa €36.

The rudder and tiller arm-
Both also made of muck metal. Rudder is embossed with what looks like a flattened cat! Reminiscent of the Irfan view graphics SW logo. It's probably usable fettled up, slimmed down and polished.
At least the shape is right and the stock at the right angle according to my Abdiel class plans, which incidentally are much better than the Deans plan, but it's HEAVY at 50gm. Stock is 2.35mm steel which is OK would have preferred 3mm though.
The tiller arm (pic 5) is weird and would need a bit of work! The indent for drilling out for the stock is 3mm not 2.35 and a miniature PK screw is supplied as fastener!!!
I will replace that with a home brew from brass plate and a split collet to clamp it to the stock good and hard.
Patterned on the plastic version I used on my Sea Scout. Or I could use my mini mill to machine indents in the stock for a grub screw. Tending more towards the clamp though.
Stock tube is rough cut brass tube. I will add a flange to the lower end as a seat for the washer I always put between the rudder and the hull.
Now to the real villains! The shafts and tubes!! Where to start!🤔
OK - the shaft, now I know where the expression 'You've been shafted' comes from😠
Advertised as stainless steel they look more like ordinary carbon steel to me. Maybe there was a nickel shortage? First inspection under a spot lamp indicated that at least one was either bent at the end or the thread was not concentric. Testing on a glass plate confirmed this. A guarantee for 'shake rattle and roll'😠 Junk.
The toobs-
Shaft is 4mm Ø, running tube is 6mm Ø. Leaving 0.5mm for the 'replaceable bearings'. These turn out to be short roughly cut lengths of 5mm tube. The outer tube has been 'crimped' using a centre punch to stop the 'bearings' vanishing into the interior. Crude to say the least.
Bear in mind that these ships were capable of 40+ knots so I don't want it tootling around like a Clyde Puffer.
My Manxman will be fitted with a pair of Trackstar 550 21 turn motors, half a kilo of brute power😁, running on 3S batteries. With these shafts and props it'd probably shake the stern off. At best it would sound like Steptoe's cart on a cobbled street🤔
The finishing of these parts is appalling. The so called bearings are not de-burred, or even cut square! Literally hacked off with a junior hacksaw by the look of them.
(PS Even I possess a mini electric side cutter (a few dollars from China - where else?🙄) which guarantees a clean square cut in seconds!)
The outer toobs look to have been de-burred with a countersink bit, leaving a sharp outer edge which is guaranteed to chew through the plastic end washers supplied☹️
Conclusion: chuck the Deans toobs and shafts into the bits box for use on non-critical odds and ends and make my own from stock silver steel and an 8 or 10mm brass tube fitted with sintered phosphor-bronze bearings.
I will fit stainless steel thrust washers at both ends as usual, with a locking collet at the inboard end and adjust for max 10thou play.
Could at least use bits of the Deans junk to make oilers for the the new toobs😁
The rest of the fittings are not toooo bad, just needing mucho fettling up, flash removal etc. The 'modeller' has to have something to do - otherwise just wait for Trumpeter or Tamiya to produce kits at a reasonable large scale😉
Summary: If I'd known all this beforehand I would have just bought the hull, which is superb, and used my plans (better than Deans😉) and Shapeways for the rest.
Two positives😉:
1 The hull is excellent, well detailed and not flimsy like the vac-formed stuff. Once the transverse beams are in it should be no problem at all.
2 An excellent etched brass fret is included, although I strongly suspect that they may be 'bought in' possibly Eduard? This greatly simplifies building the massive mine/cargo handling cranes these ships carried. The fret also provides a considerable source of 0.5mm brass strip for all sorts of odds and ends. I often use this for replacing over-scale thick splinter shields and the like on plastic kits.😊
Gripe over😉 Will I buy another complete (🙄) kit from Deans? NO! Maybe a hull though - IF I can't get what I want from Fleetscale!
Cheers All, Stay safe and enjoy whatever it is you're fiddling with during Lockdown👍

Sorry for blogging up your clog Nerys😔😁
