Welcome Jeff - paddle wheels! - there is not a great range available - Graupner make a 1:40 scale plastic
kit [but of feathering design] - search through GOOGLE for Graupner, but go to the PD photos folder
PS Reliant - Stuart Badger shows his method of brass & wheel construction
PS Pevensey - Dai Powell has posted some excellent fabrication shots of wooden construction
PS Decoy - thats mine - a basic copy of Stuarts version although non feathering
Now we do not advertise, but one of our members [Mike Mayhew UK] manufactures marine model
fittings and I am sure brass wheel sets are available - regards Derek in Australia
