Hello to the 'pair of W's' Rob and Dean.... thanks mates, loads of fun,.... Rob, updates on your casting of the RSW engine? |
| Bogstandard:
Rob, I haven't been following this post, purely because of the heading. I drool over being able to cast things myself, but not having the room or bodily temperament, I just can't. I do cast up the odd lead hammer now and again. So I thought I had better have a look see, because casting posts don't usually go on for this long, and what do I find, most of it isn't about casting at all, but building an engine. Now that is something I can follow. Great post, keep it coming. Bogs |

Hi John, thanks for your kind words, the thread simply evolved from the casting stuff. I had thought about making a dedicated engine build thread but just didnt. If anyone wants it moved, or the moderators think it should, no problem, just let me know... only too happy.... Tonight! I have one half of a crankshaft...... but first some sunny bling.... for no other reason than it looks pretty in the sunshine..... Now for more serious stuff... the crank. It has been machined up for some time, just now the linkages are finished the time seemed right.... it was an exercise in jigging or more accurately just clamping, and silver soldering..... Looking rather 'busy' now.. FINALLY! The shafts were left very long to allow easy alignment and then cut and filed afterwards. Originally I was going to press fit the thing together, after I changed my mind and decided to braise it I had to relieve the clearances a little to allow solder penetration. Thats it for now, I have more shop time this weekend and hope to produce the plug for casting the entire engine room floor.. this will have raised bosses to mount everything to... its a simple thing so I might even get it cast up... we will see.... Cheers all.. Rob |

Now, with it all together, it looks like it really means business, Rob! Doing great! |

Yes Dean, Im highly motivated... damn the lawns..... I also have a site manager who is on my case quite regularly... Gentlemen... Meet Vespa.... Im surface grinding plate right now... she doesnt like the noise...... So I had to stop..she told me so...... I was doing this... And seriously... I think the pitch wasnt comfortbale cause she was really quite pissed off... until I turned it off... It a flywheel grinder which I use to surface steel and cast iron... Tonight was supposed to be finish the second crank half....but I left the crank cheeks at home..... So I started making the reversing links... but I needed 5mm plate and only had 6mm in stock...soooo out came the grinder and the magnetic chuck....... damn useful thing... Cheap too... she only cost just under $10,000 au, of course during the week she actually DOES grind flywheels for a living.... under sufferance of course, til the weekend arrives and I use her for useful stuff..... So Im making the plates which the Stevenson linkage rods attach. More pics of the design later it all fits here... And thats it... the shop is about 3kms from home so I cant just drop out and do stuff... it has to be planned to some degree.... it also ajoins to a mates business workshop, we have an arrangement... tonight his wife grabbed me and told me I was joining them for dinner... so not much actually happened as a result... Vespa enjoyed the pork chop bones though..... anyway, shes tired and has clocked off, so I have to go...... Much more to come over the next few days.... Cheers all Rob |
