I am looking for ideas!
I wanted to make a ball joint taper reamer. I believe the taper angle is
7.15 degrees. 1:8.I need to go up to around 19 or 20 mm diameter from about 11 mm.
I have wondered about trying to get a reamer ground for the job or trying to do it myself.
I do not have a taper turning device but could offset the tail stock to turn a bar down to match the taper.
I have thought about grinding down a pin reamer or other standard reamer to the size, but unfortunately would also loose and have to grind back the cutting rakes and I do not have a tool grinder.
Searching on Google, (ball joint taper reamer automotive -hip) I get lots of answers, but many point to basic taper reamers to sort out miss-matched holes and repairs to sheet metal but many never specify the taper used. One that do say 8 degrees.
I have managed to find one company that actually sells what I want but thought postage from Portsmouth, New Hampshire may be a bit excessive.
Can anyone fabricate me a taper reamer or suggest how I may grind back the rakes without the tool grinder set-up, just normal and basic lathe and milling machine set up.
Perhaps if anyone knows of a supplier in the UK I would be grateful of the information.
