Hi I'm seriously thinking of reshafting my Apex 99s, currently apex 4s in them. I have a pulled set of TM R11 fujikura motore graphite stiff shafts which I'm thinking of putting in. Anybody using the TM shafts any advice

It's easy to ream a hosel to .370 with the proper tools.  I'd recommend using a drill press, so you can set the depth, with a .370 reaming bit.  I purchase my reaming bits from Golfworks. When using a reamer bit properly you will not increase the depth of the hosel; the hosel will only be "widened" to .370.  If you use a regular drill,  you could easily increase the depth of the hosel because regular bits are designed to "drill".  Reamers have a blunt point and are designed to "widen".  That said it's still possible to increase depth with a reamer IF you don't use a drill press with a "depth setting".

One tricky procedure when reaming the hosel is maintaining the club in the precise position.

Unless you have a Reaming Vise setup on a drill press, then I suggest an alternate method.

 

Using a drill press is without a club holder setup.

 

1. First find the drill bit which is the size of the exiting bore.

2. Place this bit in the drill press, then slide the club onto this bit.

3. Use this as your alignment procedure to clamp club.

4. Now clamp the club which you intend to bore.

5. Change drill bit to ream bit and use cutting oils.

 

Note: when boring clubs, they become very hot.

 

One inexpensive item which most hardware stores carry is a "pipe flaring tool"

These are useful to hold the hosel in a drill press, precisely and firmly and also protect the club from vise jaws when clamping in position.

Great idea for holding the hosel is it reamed to exactly .370 what's that ?3/8 works out as. 375 almost which 9.4 mm, are the hostel actually .370 it seems an irregular size in both inch and mm

Iron hosel width is either .355 (taper) or .370 (parallel).  Reamer bits which are specifically designed for reaming .355 to .370 are available at Golfworks and a few other companies that sell golf specific tools. 

 

Here is a link to reaming bits at Golfworks: http://www.golfworks.com/product.asp_Q_pn_E_GW0115

 

I use a vise which is designed to hold the clubhead while reamining.  I have fixed this vise to my drill press and lined it up so all I have to do is lower the reaming bit into the hosel.  I have the depth preset on my drill press.  Here is a link to the vise I use.
