Steel backplates for chucks

| 113 forum posts 2 photos | Hello I have a Myford s7 and I bought pre machined steel back plate
for my chuck.after drilling and fitting it on my new chuck
someone told me that using steel backplates can cause excessive wear
to the mandrel and it is much better to use a cast iron backplate
is this true? or is it ok for me to continue
to use the steel one
Thanks in advance Best wishes Martin

I have been using steel backing plates on all of my chucks for years & the screwed spindle nose is still in excellent condition. The important points to remember when fitting chucks are that both threads are spotlessly clean & well lubricated & that the chuck is not excessively tightened. I only tighten the chuck hand tight & have not had any problems.
I use cheap toothbrushes to remove any swarf from both threads & then wipe both with clean cotton rag moistened with kerosene. Then lubricate well before fitting.
Don.
