The smaller scales are more fun than a barrel of anything larger.

Cleaning rust without warning the metal.

I have seen varieties used for rough sharpening or breaking sharp edges.

Re: Anyone up for a game of name that machining accessory?

In many case, special tools are created for a specific job. I have dozens for building steam pumps...but if you had never built one, you would have no idea regarding their use.

The last picture reminds me of what is called pumice -> but without holding it, probably a WAG.

Re: Clausing 8520

Probably more than the dials.

I would offer that the cross screw itself and lift shaft (crank to gear) are bent.

The lift shaft is a straightforward turning project.

The cross screw might be repaired by cutting off the bent end and stubbing a new section on it.

Re: Did I buy a milling machine or a mistake?

or put a big strap on the pulley?

years ago i had a similar situation -> I put a LONG V-BELT between the pulleys so that I could clamp the belt together between them with a Jergens parallel jaw (wood) clamp.

Re: Did I buy a milling machine or a mistake?

Amazing that all of you have similar mills purchased by your father in the 1980's Making me feel old -> since I have one it these mills that I purchased in the early 1980's when I was in my early 20's. They are not bad mills, as long as you go slow and understand their limitations. I built my first ...

Silicone on O-rings is a sure sign of inexperience.

Re: tractor engine top end rebuild

Nyle is correct -> in had completely forgotten about that aspect (getting old and has been 40 years since ripped a gas turbine apart). Does the manufacturer list a nominal length -> beyond which you toss the stud? I seem to remember that Mitsubishi also used to specify a minimum diameter of the turn...

Re: tractor engine top end rebuild

The bottom of the sleeve will not leak because there is no pressure there, as opposed to the top. My BMW air cooled cycles had nothing between the cylinder and the crankcase except a nice finished surface. It is little more than an overgrown air cooled VW engine -> a tried and true design. Didn't De...

Re: tractor engine top end rebuild

I wondered about the history of head gaskets on this engine. Seems like a lot of stacking of components and one long bolt to secure them. If you are looking for a minimum of 350 PSI compression with heads, cylinders and bolts potentially going from 0C to maybe 100C+, the expansion and contraction o...

Re: tractor engine top end rebuild

ever put 3 or 4 hose clamps together? :shock: Question: the tool was made in the same country as the tractor? the ship problem was a lot of all you suggest. They even had one crack in two in drydock before ever hitting the water...that's when they finally acknowledged that they had a problem (duh......
