roymattblack Posted July 7, 2015 Author Share Posted July 7, 2015 No developments to show regarding the body shell parts just yet... I've re-shaped the cam covers somewhat, as the Eaglemoss parts are laughable. The timing chain end has been thinned, the cam cover rounded and the bolt recesses cut in. They are now cast in resin. The odd resin 'patches' in the pictures are castings of small acorn nuts. Each one needs cutting out and then fitting to the cam covers after painting. Roy.

Codger Posted July 7, 2015 Share Posted July 7, 2015 A huge amount of work, cutting and casting. But a fantastic transformation. Great and dedicated work Roy. Link to comment Share on other sites More sharing options...
roymattblack Posted July 7, 2015 Author Share Posted July 7, 2015 Many thanks mr C... A little update: I've reshaped the front end of the cylinder head, altered the oil filler neck, removed the 6 plugs but left the blanking caps - as per the real DBR1 - all ready to fit 6 x 2 sets of new plugs. (12 in all) The cam covers fit nicely, but still 32 acorn nuts to add. I've repeated a previous picture to compare the parts 'before-after'... Roy. ...and how the bits were originally...

roymattblack Posted July 7, 2015 Author Share Posted July 7, 2015 (edited) Shame, shame on Eaglemoss... Roy, what's best way to remove those tiny nuts from the casting sprue? I'm still working on that - maybe just cutting them out with a sharp blade. I'm testing a piece of sharpened small bore brass tube though, pressed down hard over each nut. It cuts a round circle with the nut in the centre, so it looks like a nut and washer... Push it out of the tube with a piece of rod. Roy.

roymattblack Posted July 8, 2015 Author Share Posted July 8, 2015 Thanks KP... In answer to Mr C's question about the acorn nuts: I decided to go with the 'tube' idea as it seems to work fairly well. I used a short length of small-bore metal tube, sharpened one end using a needle file inside, and a flat file outside. Put the tube over the resin nut and give a tube a tap with a pin hammer. A short length of metal rod pushed down the other end of the tube ejects the nut, complete with its 'washer'. I had a small bag of real miniature acorn nuts left over from my Pocher Rolls Royce Torpedo. They were just stuck to a piece of plastic, a small wall built up around them and silicone poured in. Once set, peel the rubber off and just a drop of resin 'scraped' over the surface. 10 minutes later, peel off a little sheet with 7 nuts on it. Spray chrome silver, cut out - done. FAR cheaper than buying the 50-60 acorn nuts I'm going to need for this one, and I'll no doubt use umpteen more in other builds in the future. The 5p piece in the picture is to give scale to the size of the nuts. Roy. 2 Link to comment Share on other sites More sharing options...
roymattblack Posted July 8, 2015 Author Share Posted July 8, 2015 Just a quick update on the acorn nuts. Whilst cutting some out, I remembered that I have an assortment of hole-cutting pliers for making gauges etc. I fished out the smallest I have - 1.5mm - and hey presto. A perfect fit! Chopping the nuts out now is a doddle, miles quicker and far neater. Roy. Link to comment Share on other sites More sharing options...

roymattblack Posted July 9, 2015 Author Share Posted July 9, 2015 (edited) I've made the distributors - two of them, driven directly from the camshafts. They were made from bits of plastic tube and oddments, then cast in resin so I could get two the same. Some detail painting is still needed on them. Wires are now attached, ready to go to the coils and the plug lead tubes that will eventually run along each side of the head. Roy.

Codger Posted July 9, 2015 Share Posted July 9, 2015 Beautiful details on the distributor bodies. Making those and then casting them perfectly - you're a wiz at that now. Link to comment Share on other sites More sharing options...
roymattblack Posted July 9, 2015 Author Share Posted July 9, 2015 Many thanks Mr C. As a slight add-on - I've taken all of the ignition leads off. They just look too thin. A bit of re-wiring to do now... Roy. Link to comment Share on other sites More sharing options...
roymattblack Posted July 10, 2015 Author Share Posted July 10, 2015 Two engines on the go now... I'm going to build another as a 'stand alone' piece. So far: Roy. Link to comment Share on other sites More sharing options...
toms111s Posted July 10, 2015 Share Posted July 10, 2015 Roy, how do you manage to position and glue parts as small as those acorn nuts? I would have serious problems trying something that fiddly, the glue would be everywhere and the nuts would be all over the place. Link to comment Share on other sites More sharing options...
Codger Posted July 10, 2015 Share Posted July 10, 2015 (edited) Two engines on the go now... I'm going to build another as a 'stand alone' piece. And you do all this while strumming a few notes with the other hand??? You have a beautiful as-cast finish on the parts as opposed to 3D printing. Those engines are beautiful kits by themselves...

I would have serious problems trying something that fiddly, the glue would be everywhere and the nuts would be all over the place. A good old magnifying lens/lamp... A dot of Cyano on the cam cover where the nut will go, and then drop it in place with tweezers. Not too difficult really. Just a tad eyeball-straining. And Mr C... I don't think I'll be making DBR1 engine kits in the near future. These two are already causing hair loss... Roy. 1 Link to comment Share on other sites More sharing options...
roymattblack Posted July 11, 2015 Author Share Posted July 11, 2015 The second engine is now catching up with the first. Also, new ignition leads as the original black ones were too thin, the second set in yellow were too modern, so now they are a nice drab '50's brown. (But I've kept the coil lead yellow just for a bit of variety.) Roy. 1 Link to comment Share on other sites More sharing options...
S5 modeller Posted July 11, 2015 Share Posted July 11, 2015 Roy you're doing some serious reworking on that engine. To me the engine looked fune, but now you pount out the inaccuracies, it really is a bad job. Can't wait to see more progress, definitely a silk purse from a sows ear moment Matt Link to comment Share on other sites More sharing options...
imster Posted July 11, 2015 Share Posted July 11, 2015 good idea to cast the engine for a standalone! Link to comment Share on other sites More sharing options...
roymattblack Posted July 11, 2015 Author Share Posted July 11, 2015 I'm doing a second engine as for the vast majority of the time after a model is built and in a case, the engine cover isn't opened so the 'innards' are never seen. This time, it WILL be seen! So far, one head has the distributors, leads, plugs and cable tubes. I've only placed the head on the engine to see how it looks. It won't be attached for quite some time yet. Roy. 1 Link to comment Share on other sites More sharing options...
Spookytooth Posted July 12, 2015 Share Posted July 12, 2015 Coming together nicely Roy. The older looking plug leads are the part. Also I like the home made distributors. Simon. Link to comment Share on other sites More sharing options...
