The Forums will be down, Friday, November 24th starting 8 AM PST for upgrade.We'll probably be down until 1PM PST, but it might be longer. I'm doing a major forum software upgrade, so I expect the forums to operate somewhat differently when we come back online.
yes - the photo of the soldering on balsa should have come with a warning - something like "don't try this at home" there are better, safer soldering pads available - but I seem to be stuck in my ways - as you know ..... and about the rear suspension - yes - excellent and thorough hx - I oversold this Cooper's innovations Ferry Porsche has to be considered the Father of the modern race car J Cooper would have seen - and studied - the Germans at the pre-war British Grand Prix races and like Chapman - he was anxious to try his own designs after the war .... anyhow - I've got a U joint fetish - let's keep this a secret ..
some more shots to explain the process my first attempts used U joints made from solid brass rod but I wasn't satisfied with the plastic yokes - which had to be made in halves so I then made the joints fr tubing - which had to be filed and sawed to tiny joints that would fit into the yokes as close as I will come to brain surgery on this project ...
"three little pigs"... time for some U joints this Cooper was one of the first race cars with indep rear suspension - using U joints they are relatively compact - they don't have to be as hefty as later U joints on car w larger engines So I tried several different methods of construction - using U joints soldered from brass my first attempts were too large - and a re-check of my photos led to some construction changes I will use the top one in the photo - the U joint is made from 1/32 brass tube - soldered and drilled - with .019 brass pins through the yokes the yokes are filed drilled and sanded from .60 x 1.00 evergreen stock, with some discs from round stock
Aber Chains : sold out on the BNA Model World site (Australia) have a look around - I purchased these w/in the last yr - can't recall which internet seller check the major model sellers catering to military modelers photo: current model assembly bench it takes one of two events to force me to clean my work bench first: an act of Congress second: a major hurricane this time it was the hurricane ..... Merit kits: got any un-builts left ?? which ones ??
post-Irma ........ note that there is a small bike chain sprocket in the picture of the crank case shown above the chain travels to the transmission - alongside its casing - and then runs back to a sort of transaxle casing difficult to machine these - so an internet hunt before the storm turned up ETSY - which sells old watch parts in bulk some of the parts will be used for the sprockets -which are different sizes on the crank case and the trans case some of the smaller gears will turn up in a later Bugatti project ..... the chain will be simulated with photo-etched "chain" links made by Aber they don't match perfectly with the watch gears but it should look okay - will probably try to solder this together
some more detail - including some structural webbing cast into the crankcase - added w bits and pieces of evergreen strip the head removed for some more mods and the crankcase sides lacked the cast fins or slots added with sections of evergreen railroad siding sheet
have you ordered your Resin Jag D yet fr Profil 24 ?????? oh, the storm ... luxuriating in air conditioning 100 miles north of Miami - house will be fine - whenever we get back - florida "gold coast' did much better than the Naples ft Myers area ...
so the casting did not include the bottom of the crank case - which I am adding - it will poke out of the bottom of the engine bay - just some evergreen strip and liquid glue - then sanded and filed to shape and some initial crank case details - again fr bits of evergreen stock
hunkered down in Jupiter and still w power so here's an update w some work that was actually done a couple months ago the kit engine casting - a Norton Manx - is a two piece affair that shows its age but it's a start ...
