Spider for Lathe

[Hammerhead]

I have seen some previous post on the bolts used for spiders on the lathes, front and back. I see most people have drilled and inserted copper into the head of bolt.
Would it be okay to use aluminum bolts instead?

You would be better off with setscrews and not cap screws.

I use Nylon screws set into the setscrews, don't know as I want copper or aluminum
marking the barrel....

I've used copper for years. It doesn't mar the barrel even if it slips.

If aluminum was used against the barrel and it should slip, I would fully expect that would mar the barrel. Aluminum is an abrasive. I'll stay with copper.

+1 for copper inserted into the bolt or you can actually get copper bolts.

I guess I am just too lazy. I use split copper pipe arround the barrel, under steel screws. Been doing it this way for many years.

Rustystud, now you are talking.
My father in law is a retired plumbing contractor.
I know where there are lots of scrap pipe laying around.
Thanks for all of your post guys.
