How do you cut keyways into pulleys for example?
I've found a site that sells broach's and bushings and understand that you can use a press but how do you attach the broach to the press?

Any decent machine shop should have a broaching machine, just make sure you give them the bits you want to fit to gether so they can make sure they fit *wink*

I love the way he says that the broach is very brittle on several occasions and then bangs it on the work bench to get the swarf out of the teeth :)

He's putting together a list of tools for me to invest in, including a CNC milling machine :(

I want to retire before I reach 60 - no chance.

You need to add a shaper to your shopping list.

A nice hydraulic press would suit the broach kit you (Paul) are about to buy perfectly.

Preferably a motorised pump, so much easier to control than the manual pump ones.

Well I was looking at a arbor press and was going to purchase it myself but he decided that a larger hydraulic press was more suitable because we can use it for more things.

Matty, where does a shaper come into it?

I used a shaper to cut my keyways out. We used it to cut the keyway to size then finished off with a file to get a good fit with the key...thats where a shaper comes into it. *wink* A shaper has soo many uses. lol

I utilised what tools I had (read as my mate had) and worked well.
