Thanks Russ, I'd like to say it's all plain sailing (pun), but I had a hiccough this afternoon. I was drilling and tapping some of the screw-keys. I think it might have been Fred, on here, who called them "Po' boy keys". Very apt! Crankshaft (26) (600 x 450).jpg and suddenly found that the shaft wou...

Set the D.T.I to zero at Jaw No 1 Crankshaft (22) (600 x 450).jpg Rotate by hand and check the run-out as you turn. Mine is worst on N0 2 jaw, note 0.0015". This will be checked again at each intermediate stage as the chuck may not settle at exactly the same reading next time. The run-out here will ...

Sorry Guys, no I hadn't abandoned the project, just took a few days off. Though I do have to say progress has slowed, as I'm taking greatest care not to need a re-make, and it nearly happened! :o :o I made a drive flange and a thrust spacer and measured the shaft length and forgot to add in one web ...

"I just looked at the Harbor Freight web site and they will sell you a 3 h.p. engine for $130." In Pennsylvania they sell a 212cc 6 horsepower OHV Gasoline engine at $99 on sale. I have bought a few over the years, and they have always performed very well. Small steam plants, perhaps similar to the...

Nice!

You do realise that the full name of that tug is really "Hugo, where I go"!



Sorry, lock down is obviously getting to me!

One is now done! Crank Webs (17) (600 x 450).jpg Further to Dietrich's idea, I think in the vice, the curve for the boss would be difficult with a fly-cutter, meaning they would probably need to go on the Rotary table anyway for finishing off. The raised bosses would also make them difficult to grip...

Hello Mike, nice to see, but why you didn't span the four parts together in a vice and finish the surfaces in one step? So all parts would be equal i think. You can use a flycutter or a milling head to get a fine surface. --- Dietrich Nice thought Dietrich. Four together would be over 100mm thick. ...

Crank Webs (13) (600 x 450).jpg Too late now to change my mind. The bulk has been removed with the band-saw and the set up and method tried by giving a dry run-through using the laser centre/edge finder for the tool. It works! (or seems to!) Crank Webs (14) (600 x 450).jpg Set up ready to go when s...

Welcome Brian. Lots to look at on here!

Beautiful work as always. Really exciting seeing the whole thing come together. Very satisfying too Tom. Not a short term project for me, but then there are a lot of distractions. I would love to build a steel, or wood, hull for it, but that is unlikely due to space limitations. I have the technolg...
