Re: Core Boxes: Why were they usually made before the pattern?

I rarely use core boxes because I have no need, I made the patterns in Styrofoam, and stuffed sodium silicate treated sand in every crevice and opening and then hardened it. All the castings in the first photo required only one core box. The place I had to make the core box for was the two long hole...

Here is an interesting article on tractor repair. It deserves comment. Do we already have such a situation with automobles? I used to be a "Shade Tree Mechanic", but got too old to "get out and get under"!

Re: Machining Cylinders - How to Do?

Back in the 70's I bored a Little Engines cylinder casting on our Bridgeport using a Bridgeport boring head.

No DRO's in those days, had to carfully count each dial revolution; things are much easier today!

Re: Considering a DRO

Here is a site for the "Rolls" of DRO's, they have lots of good information. They also own ACU-RITE. I have an ACU-RITE DRO that came with my lathe, and a Heidenhain I installed on my rebuild of the B&S #2 Mill. Here is their current device for la...

Re: Rail spacing for 7-1/2” gauge Equipment

I have made my own track gauges out of steel bar, but I just noticed Precision Steel Car Co. has aluminum gauge bars for sale: I use 7-9/16 for Straight Track, and 7-5/8 for Curved Track also, and it's easy to misplace a bar. My steel bars, 1-1/2" ...

Re: older milling machines

Spro, I have two older B&S Mills, a 1908 #1-1/2, and a 1924 #1 they were both installed at the older school building where all shops had line shafts powered by one single electric motor near each shop. When they were transferred to the new school building, in the middle 1930's, electrical distributi...

Re: Show us your milling machine!

It is interesting to start back at the beginning of these posts, 2010, and see that many photos are now missing. This is one of the problems of storing photos, etc., on another site, it may go POOF! Yahoo did this to all its Groups this December, and left only a shell of email addresses, which is ab...

Re: Kit Iron Castings

Speaking of "Tilting at Windmills", I tried to do my own Ductile Iron at the school were I taught. They had an old Rotary Arc Furnace, but no way to accurately measure temperature, it was done by watching the Watt-Hour Meter, and calculating for the weight of Pig Iron at what input energy it should ...

Re: Cylinder Borning

Here I am in 1971 using a relatively new (1968) Bridgeport and a Bridgeport Boring Head to bore all four cylinders of a cast iron casting purchased from Little Engines for their 0-6-0. A DRO would have helped in locating each center, but there was no such thing in 1971, that I knew of; had to just c...

Electronic Leadscrew

Here is a post that was put on the new Harrison Group that migrated from the ye olde Yahoo site that will die in a few weeks. I ran it by Harold to see what he thought before I posted, and it is below. My Harrison VS330TR has almost every kinda thread imaginable on it already, I would not need such ...
