Re: A Real Dirty Job

Squaring the spring hanger cross beam slots. I used my Dore Westbury bench mill for this purpose as it has a rack and pinion lever operated quill (as well as a fine feed hand wheel). I have not described this method before so here it is. To begin with, the mill fought me all the way to the bitter en...

Re: Understanding types of copper?

Dianne,

Had a quick look on the internet. Did you try New West Metals Inc.in Winnipeg? Their toll free number is 1-800 665-7625 . They have no minimum and will cut to length and deliver to your door. They have hard drawn copper tubing in straight lengths, types K,L, M.

Dianne,

Any decent plumbing supply house (where the plumbers go) should have it.

Re: Machining Setup's with Few Comments

A semi universal multi angle square or round tool bit grinding fixture to grind miniature slotting tool bits and many other types of multi angled cutting tools in my surface grinder.

Re: Machining Setup's with Few Comments

Harold, The part which I was machining was half round so no matter how it was held lengthwise (and it needed to be held lengthwise to machine the sloped ends) in the vise there was only a line contact between the vise jaws which was not enough to resist the milling forces so it had to be mounted on ...

Re: A Real Dirty Job

Producing square ended miniature slots from rounded end slots. It is all about the setup and the tooling needed (and the tooling needed to produce the tooling). I have two separate ways of doing the above. One of which I pioneered (as I have never seen it described anywhere - other than in my Jossli...

Re: A Real Dirty Job

The next operation was to mill out the two internal spring hanger slots. One was 3/32" dia. by 3/16" long and the other was 1/8" dia. by 1/4" long. These slots need to be central. Do the layout work first. See the first photo. As the rough spring hanger blanks were left 1/32" oversize on length widt...

Re: A Real Dirty Job

Two new front leaf spring hangers roughed out for the four wheel trailing truck. Endless milling work here. In my previous posts where I referred to the "rear" spring hangers (on the truck rear leaf springs), it should be the "front" spring hangers (on the truck front leaf springs). There is a front...

Re: Burke #4 Questions

Glenn,

I have a custom adapted variable speed controller and electric motor (from a tread mill) on the Burke #4 mill which allows one to turn the motor at any speed (from 0 rpm up to maximum rpm).

Re: Machining Setup's with Few Comments

A difficult holding job. The part shown in the previous post was next setup for a 3/32" drilled/reamed cross hole and then both ends of the part were sloped at 45 degrees to finish the part. The cross drilling operation was not particularly difficult but holding the part to slope both ends of it was...

Re: A Real Dirty Job

As I mentioned previously, Murphy kept urging me to delve into the innards of the trailing truck to see what wonders lay there. All along, I could see that the rear leaf spring hangers were not in the best of shape so I finally took the rear of the trailing truck apart to have a good look at them. A...
