need a bullgear for myford ml4 lathe

The gear would not have to be made from the original cast iron, unhardened steel, or even aluminium would work. The bull gear on the Atlas 12 x 24 we are working on at the museum is made of zamak, a zinc alloy like the mazak we have here in Blighty.

Hello Tim,

Just looked up Lea Francis on Wicki. As I thought the modern company was founded by Barry Price, in the 1980s to provide spares for the old Lea Francis cars. Somewhat similar to the company supplying Bentley spares for the pre RR Bentleys.

Hardly the same as a company in continuous production, supplying spares for a product which ceased manufacture 75 years ago..

I'm here to confess to a less than perfect memory, though the main substance of my post about Myford correspondence was correct. I dug out Dad's old paperwork and found that they had a larger range of spares than I remembered, though they warned that they were only available 'subject to being unsold at the time your order is received' which pretty much proves that they were no longer manufacturing them but only selling existing stock.

The 65 tooth backgear, 1" bore, was available for 16/9d, the 30 tooth backgear, also 1" bore, was a mere 9/= .

Given that (as far as I know) all remaining Myford stock was auctioned off when the original firm closed, well, good luck to anybody who is considering asking the present owners of the name for ML4 spares.

I've copied the letter and associated price lists and put them in my album for anybody who wants to read further.

Anyway; back to the original post. John, I hope that you have been able to sort something out, and I'm sorry that my post led to the thread being derailed somewhat. If you need more help, keep asking.

That would seem to confirm my 65 tooth tooth bull gear. If the diameter of the damaged one is posted, then a possible donor gear might be possible.

The bore of the ml4 bullgear is 1".

So, put us out of our misery!

Did you get together with Brian Wood so that you can restore the back hear facility on youML4?

Hi all I have now sourced a bull wheel for my ml4, Thanks for the interest I will now look forward to continuing my restoration of the lathe.
