Machining pipe trolley wheels --
« on: January 15, 2011, 05:45:50 PM »
You guys know that I've been looking for a pipe trolley for my Host rail that I built a few weeks ago. I was going to go with a pipe trolley system, but decided that this may be just the project to design my own trolley.

Here is the Hoist project from a few weeks ago --



The pipe needs a trolley to make the hoist glide. So I chucked up two of these old iron wheels that I used several years ago to make English Wheel anvils with. IIRC I got about 20 of them from Northern Tool at the time because they were on sale for $1.50 each on a closeout.



The plan is to install some good bearings, and then cut the concave radius so that the wheel will track on the pipe.



First I chucked the wheels up and used a small boring bar to cut the bores for the bearings.





After the bores were done, I used my trusty homemade radius cutter to form the 2-1/2" radius that I needed for the rail.







This cast iron cuts very difficult because it flakes, so every now and then I smoothed it out with some emory cloth to make the surface easier for the cutter to traverse.





After about 30 minutes I was able to get my radius completed with one final smooth cut.



The finished trolley wheels with bearings installed --



Next, I'll have to build a frame around those wheels. That's a job for next week.    :beerdude:

Not a bad idea AP, but I had a ton of these wheels sittin' around and I also have plenty of bearings. Besides, I just came up with this scheme last night and decided to hit it hard this morning. It was a good few hours spent in the machine shop -- not a bad Saturday.

As long as you're into this project, don't forget to install a self activating brake in the bottom of the trolley so you can leave it where you want to without the load following you. 


Good point!! hadn't thought of that.

I guess it is to late for this

I looked at that trolley system Heiny. I have a friend in Australia that could get a good deal on that trolley in New Zealand. For some reason it's much cheaper in NZ (must be the taxes). Anyway, I had a boat load of these cast wheels and also the bearings, so I just went ahead and decided to go DIY style. It's more fun that way; I really enjoy working in my warm machine shop -- a nice way to spend a Saturday afternoon.
