Small Bending Roll Plan

So 10 posts ago I posted a article on the operation of a small slip roll. I also indicated I would upload some plans. It seems there was a lot of interest in the article, so I figured I should get a plan up. I'll start with the smallest plan I have.

Most people are familiar with "Model Engineer" the British magazine that has been around since 1896 (yes 1896 and still going strong). It contains many metalworking plans and projects covering shop tools, live steam and various other model making topics. One of the plans I have found circulating on the web is an edited version of a plan for a small bending roll from Oct. 1976 Model Engineer. Its a nice plan but the pictures are all dark and not very useful.

I have a large collection of Model Engineer mags. on my shelf. Great deal I got from a retired Brit at a flea market in Thunder Bay, many years ago. On a hunch I checked them, and sure enough I had the two issues the bending roll was published in.

So without further ado here is the original plan from "Model Engineer" magazine. First picture is the cover of the bi-weekly containing Part 1 of the plan for the bending roll.










This is a well designed good quality plan, difficulty leans toward advanced, and a metal lathe is required. I have easier larger plans, but the quality here is hard to beat.

So I got a couple of days to make my property presentable and then it's time to enjoy some summer, but I think it was Arnie who said "aawl be back".

Cheers

Operating A Small Slip Roll

If you like to work with sheet metal a slip roll is a very useful machine for forming circular and conical shapes out of sheet metal. Their are other ways of doing this with hand methods, but a slip roll makes for a easy, quick, and very neat job. Good quality rolls can be expensive, The import market has brought the price down quite a bit, with varied quality.

There are many plans around the web to make your own set of rolls, I have at least a couple I would like to upload in the future.

Following is a nice article on the operation of a small slip roll from the Winter 1954 PM Shop Notes.
