Thread: 45 fin buick drum

Tweet

Don,

I read somewhere that there is a company on the east coast somewhere that does it. If I could get the CI I thought I would turn it for a press fit and then pin it or key it, I think keying would work best. So far the only the only short pieces I can find are ductile cast iron and of course that won't work. I now have the 90 fins on the front with good liners but the rest of my drums need liners.

One thing to keep in mind is cost vs value. In today's market the good, useable 45 fin typically sell for $200-250 a pair. 90 fin on the other hand go for about $100 a pair. That may change over time, but the ratio has been pretty consistent over the last decade or so. Repair, if possible, will cost the same for either.

Hi Bob,

I have two 45s and three more 90s and I will do the work myself so all I need is the CI at a reasonable (to me) price. Haven't worked at finding the CI for over a year and just thought I would see if there were some other avenues to explore.

Joe,

I at first thought I would reline with steel if I couldn't find the CI. When I mentioned that to my engine re-builder (for the 461) he told me not to do it because steel has a different friction coefficient and would not work like CI. I haven't explored that any further so don't know how true that is but until I do I will stick with CI. If I can't find any at a decent price maybe I should explore the steel angle further.

He may have said cast steel, but who know that was about 10 or so years ago.
I'm doing good to remember what happened yesterday .

Joe,

What happened yesterday, oh well, what ever it was it must not have been important.
