Hello to all!
I realise that I was spending much time thinking in all the stuff in the "I must make" list (rotary table, dividing head, tool & cutter grinder, measuring tools etc etc..) and I was getting a little stress, and no making chips at all! so I send all to hell, get some plans on the internet and give it a try!
The engine I selected no need a rotary table or indexing cuts (except for the flywell) and I really like the looking, its a vertical single cylinder engine.
I take my time to study the plans, and found some errors in measures and stuff but nothing critical and I make some adjustment to correct them.
get all my money and buy the brass (laton really, but anyways ultra-expensive!)
Finally align my lathe and mini-mill the best I could and go!
The plans call for a solid block of 10 mm thick brass for the columns that sustain the cylinder, but too expensive, I decided to make my own columns using a Assembly of sheet brass and then soldering with emmm pewter?? ??? (the stuff to solder circuits) because I don't have silver solder jaja
to be able to solder the column assembly in place I make a jig to put all the pieces together:
The two parts will be arc-welded, and I make a very emmm messy setup with 1-2-3 block to try to weld the two pieces square
but don't work very well.......but I will still use it because the error in squareness is tolerable :
here is the finished jig:
Now I will start with the brass!
(it will never go where you want to.......)
here is the jig and the 2mm brass sheet in place, now I will made the principal piece
and a little (a lot really) sand paper and got the first column Assembly ready for soldering ;D looking good!
that's all for now, I'm becoming a real model-engine-machinist!! yeah!! 8)
