Re: Cole's Worthington pup question?

I have a legal copy of CAD software compatible with Autodesk CAD. I lost my legal access to Autodesk when I retired. NP317 - that's a neat idea! I don't think it would be a free-bee considering how much work I have put into this drawing - probably 4 full days so far. The work of redrawing in CAD is ...

Re: Cole's Worthington pup question?

I think I may just offer paper copies (with a Coles copyright) just to keep things under control. Have already found a couple of measurement errors on the original drawings - one obviously wrong and another "just a little bit wrong" but not enough to effect function. I just may hang on to the drawin...

Re: Cole's Worthington pup question?

Dianne, Looks like you are duplicating the 2D drawings That's what I am doing - duplicating 2D and doing 3 views of each part. I have worked in 3D to make some relatively simple parts on my 3D printer and investment castings but nothing even remotely this complicated! That is a "learning curve" I d...

Re: Cole's Worthington pup question?

Sure Russ, I will share. Cole's is out of business so it isn't hurting them any.

Cole's Worthington pup question?

I have been transcribing the drawings for Cole's Worthington pump to AutoCAD to get everything straight in my mind before I start building one, particularly the porting. I am good on everything EXCEPT the front passage from the water cylinder to the vertical 1/8" passage that joins the inlet and dis...

Re: Brass v.s. Bronze?

The bronze I bought 20 or more years ago for a completely different use with potable water purification, a 4" diameter bar of which I have about 8" left. I don't remember the alloy but it machines beautifully on the lathe. I will test it with drilling & tapping small holes and if handles that easily...

Brass v.s. Bronze?

I am preparing to build a VanBrocklin pump from Bill S. plans.

I have a large piece of bronze surplus to my needs but no brass.

Is there any reason to buy brass or can bronze be substituted in making the brass parts?

(I have very little experience machining small parts!)

Re: Semaphores explained?

I have been playing with the same thing for an HO railroad so I have dabbled in semaphores for awhile. You said "stepper motor" so that's a good start but forget fail-safe - that complicates things considerably! With a stepper motor and lead screw, you can figure out how many steps from the most res...
