Ying Tong track bender

Well, Jun Ying anyway

 

Wanting to bend some rail, I searched the internet and found this:

 

https://model-railroad-hobbyist.com/node/15932?page=1

 

The basic watch repair tool is pretty cheap, so I bought one:

The design of the tool has changed from the article on Model Railroad Hobbyist. Rather than use the long screws and bits of tube, I turned the three pegs down in the lathe to fit some 8mm bore bearings:

I used snap ring bearings with the snap ring removed:

That makes the clearance groove for the rail flange

 

And it works!:

Would it be possible to show a photo of the finished machining on one of the pegs please?

Does that help? When it comes to units, I'm ambidextrous...

Many thanks for the photo and dimensions :)

I've found an alternative supplier on Ebay for the Jaxa Wrench, this time in the UK (so faster delivery) plus a bit cheaper (but no storage box).

Unfortunately the bearings are out of stock at present, so I'll either have to check when they'll be back in stock or find an alternative supplier.  Many thanks for posting this - I quite like the idea of making one for myself.

You'll probably find they have one or two bearings, but not three. I tried to order three of those particular ones and found they were out of stock

 

Instead, I bought three of these: https://simplybearings.co.uk/shop/p152878/6082RSNR-Deep-Groove-Bearing-with-Snap-Ring-8x22x7mm/product_info.html

 

Blow the expense!

I received a reply from Simply Bearings - they had a website glitch (now fixed) which showed the cheaper bearing as being out of stock, even though they weren't.  So 3 bearings plus the watch case tool from ebay are duly ordered - cost about 15 quid total.

Now to wait for postie.....
