Well the Blowfly manual arrived from A.M.E. It's pretty much just direct copies of the original articles though (including the old ad's on the pages, and some errors in the drawings), but at least it saves damaging the old magazines. Currently waiting to hear back from a steel distributor who's trying to hunt down some BMS for the coupling/connecting rods for me, I'm likely just going to end up using black steel. Also the lathe needs a new belt, and I'd like to get some new jaws for the 3 jaw chuck, unfortunately there's no belts in stock, so I'm waiting on those as well. It looks like the Hobby Mechanics' A10 brake blocks will work nicely though, so I'll probably order those along with a few other bits and pieces (stainless steel rod, maybe bushing materials, various sundries) from them this (next) week.

I dug out an old set of frames for a 5" gauge Blowfly that had been sitting under a bench for over a decade; this had been started just before dad sold most of the workshop machinery, and thus never got finished. 5 inch gauge blowfly chassis The rolling chassis as it was left years ago, I had to clean it up a fair bit as, aside from some spider's making a home of it, there was a lot of rust. The hornways had rusted so bad that one of the axle boxes had to be knocked out with a hammer and drift. 5 inch gauge blowfly chassis Another view of the chassis, the rust on the front axle is plain to see. After much cleaning, degreasing, and a bit of polishing it's now in a much better shape; and some fresh oil should keep it that way. Here there's some temporary adjustable coupling rods in place, and the valve gear - what little of it there is with slip eccentrics - is also visible. some of the break linkages for a 5 inch gauge blowfly Some of the brake linkages after cleaning, as there's no drawings for brakes these were designed by me. The cylinder will allow for steam brakes, hence the elongated lifting link with spring inside, The hand brake standard is fitted to the foot/running plates, which I don't have a picture of at the moment. The two pins at the bottom of the image are for the couplers.
