|Thread: Stuart S50|
OK as mentioned elsewhere I have taken up the challenge of building this machine from plans only, mainly for financial reasons. I already have about a million questions so I better have a thread for them.
First off I have a small lathe, a pillar drill, a bench grinder and a hacksaw. I'm not great on terminology yet so may need some things explaining that you chaps will all know about.
OK so far I have made the piston and piston rod, the piston gland (terminology??) and one end of the cylinder. My next plan is to make the other end through which the piston rod will pass and the gland will screw into. So far I have managed to use all the correct materials. The plans dictate that I put some kind of packing into this part but don't tell me what it is! And what do I use as a gasket?
Is this a good place to start?
Having a number of engineering contacts I can scrounge odd bits of rod and bar fairly easily but living out here anything special like 'silver steel' (is this stainless steel???) I have to get mail order. But I do have a chunk of cast iron. I went to a local scrap man I know and begged it. They cut me off a piece of farming tackle they were recycling.
Thing is its huge. About 6" x 5" and 2" thick. How the hell am I going to make the cylinder out of it cos thats not just round, it has a rectangular piece on it too.
OK more questions later
|Thread: Making lathe tools|
Hi all. I'm Chris from Ryedale and although I have been a plastic model maker for many many years I am just turning my hand to a steam engine.
Dictated by the fact that I'm skint and dependant on someone elses garage that I can't really fill up, I have a very small lathe (Axminster Micro) and I'm struggling to cut lathe tools that work. I have joined my local SME (PEEMS, Pickering) and a chap there told me for a nice finish to grind a tool with a fair radiused point on it.
This hasn't worked, it binds and chatters and generally cuts like a dog and the more I radius it the worse it gets. It was lovely too all honed and graceful
And as for parting off tool don't go there, I'm finding it easier to hacksaw the piece off and clean it up after I've looked at loads of web sites and books but its not working for me.
I have 2 sets of Stuart plans, the S50 and a beam engine. Its the beam engine I really want to make but I thought the S50 would be a good place to start and get all the mistakes out the way. I'm making them from scratch too as I can't afford the castings.
