If all you want is a different length of lever, why not take a stock item &
cut & shut it, fill with braze & re-chrome.
Sounds a lot easier to me.

I read another response commenting on the use of a broach. While a broach is used in production applications the cost in this case is of course extreme. The heating method will only find the part you desire to form to be quenched quickly when contact is made with the male part,unless of course the male part is preheated. In the case of heating to form ,a suitable part will be very hard if not impossible . You also stand a very good chance of destoying your casting. The way we would most likely undertake cutting the inside spline would be to use a cutter sharpend to conform with the desired profile. We would then center the workpiece mouted on a rotary table below the spindle of a vertical mill IE:"Bridgeport" . The work piece would be offset to correspond to the major diameter. The cutter would be driven slotter style thru the bore,retracted ,the rotary table would be rotated the appropriate nunber of degrees . The steps repeated till the spline was formed . This process could well be acheive with other machines by adapting the scheme . A lathe with a means to index the spindle would work as would a stout drill press or an arbor press. If you cannot find a local shop with these capabilities let me know . I can probably do the job for you.

A broach is pused thru ,from one side to the other dragging it backwards will only dull the cutting edges. Paul Linn wrote:> ============================================================
