What am I doing wrong?

[fergie35]

I have had to put new spindle bushes in my MF65. However they are the unfinished type, as thats all you can get as far as i'm aware for a 65. However, I seam to be having to ream a lot of material out to fit the spindle (the spindle measures 31.6mm).

I have an adjustable reamer with centre, however you can only cut out about 0.003" at a time, and I need to remove about 1/32" I would think. At this rate it will take ages to ream, I've been at it 2 hours and hardly got halfway to one bush being reamed correctly.

What am I doing wrong? Are my bushes faulty? they are sparex ones i bought years ago.

Anyone know of an easier solution for the 65?

Now Then..
I know it's of no help, but it is a horrible job and you're doing it exactly how I have done it. I've also tried a honing tool,,,, it's no faster though.
The reamer leaves an undesirable finish I've found so usually hone when it's nearly right..

Tedious job. Churchill made dedicated reamers for spindle and centre vertical shaft bushes with a tapered bush to go in the opposite end to keep the reamer square.

An unfortunate leftover from when fitters made things fit
Fine when people only got paid just enough to stop them from starving

Never use any abrasive in reducing a bush as the grit sticks in the metal and becomes a grinding paste. Cutting tools are the only way.

I've sorted it. I borrowed another reamer and that was sharp and it cut the material away in minutes.
