Reaming depth (sierra uprights)

[squbti]

hey andy, thanks for the tip . sounds like an easy job , did you use any cutting oil or something like that? for the mushrooms i´m planing to use stinless steel do you think the reamer is up for the job considering that its a harded metal?
thanks

i used a few drops of 3in1 oil whilst cutting, not alot but enough to just "help" the reamer.
as for stainless steel, i honestly don,t know, sorry.

cheers

hmmm you got me thinking there andy , maybe i shouldnt use stainless then i know from working with stainless that its harder to drill & cut so i dont want to risk braking the reamer & i was also thinking rust building up between the two metals. so what did others use for the mushrooms?
thanks

i was lucky with finding my mushrooms, £5 for the pair off centered hole too.

they look like they are made from high grade steel .

Can anyone tell me what taper the ball joint is? Because I am using a BMW upright I will have to have a part made due to lack of me having access to milling machines etc. May as well get who ever makes the part put the taper in as well.

hi there,. i made mine from stainless cut a treat in the milling machine with some rochol cutting compound nice slow spindle speed

did the bottom of the uprights in the same way worked beutifully

used the handy reamer from axminster shortened it so i could get it in on the Z axis and stuck it in a 5 - 20mm chuck as it wont fit in a standard 13mm chuck
