Router Jig

[nvreloader]

Well guys here is my first post,

I have a BP mill, J head, which is in need of some head rebuilding, (bearing going out,I think,
and I am looking for a good place to sent it for a check out/rebuild etc,
on the West coast if possible, so I can't use it at this time.

I have my eye on a Grizzy 0755 mill as a second mill, until I can get it.

For now, I have to use the router to hog out a couple of Blue laminated blanks for rear grip pistols actions,
for the bbl channel and action inletting etc.

Some where I seen a jig info, but can't find it now that I need that info,
that hold the blanks and allows the router to cut what is needed.

Does any member have any ideas/solutions on a jig of this type,
or where to find info on this jig?

The Dremel tool just not cut it with this laminate stuff.

Tia,
Don

This is a fixture I made for inletting on my BP cnc mill. It is essentially 2 self centering vises on a base that will slide from side to side via a dovetail gib. I had to make slide because I only have 18" of x travel, so it has one position for the receiver inlet and then is slid to the other end for the barrel channel.
One thing to consider in your circumstances, is to make a bracket to mount your router to the spindle of your mill. I have seen several versions that use a simple split clamp to mount the router motor off one side of the spindle. One thing is for sure, you need all the rpm you can get with these laminate blanks.

The drive system is pretty easy to rebuild, I think I paid about $50 for all new bearings in mine. The spindle is another matter. I had my spindle rebuild by a local spindle shop, about $900 with the 5 bearing upgrade, about $600 for a standard rebuild. Just pull the quill out and send it to a rebuilder. I used C-M Precision Spindle. http://cm-spindle.com/contact.html

Thanks for the info,
Any suggestions on where to find the router attachment info for the BP?

I just found the site that has the router jig for stock blanks,
see info here,

Thanks for that info,
I don't have the experience for that kind of work on a BP mill.

This mill was "Road hard and put away wet" as the saying goes,
so I would like to get a reliable shop to check,
replace any parts that may be needed or questionable.

I have found several places that have replacement heads, all used,
but not sure I would trust the info given with the prices from $1900-2500 range.

I would think that for that price, I could have my head rebuilt??
I just can't find a West coast source, so far.

These are the only guys I could find that specifically advertise machine rebuilds in the LA area. http://www.dansmachinetoolinc.com/rebuild-repair-bridgeport-milling-machine-tool.html I'm sure there are others. Looks like everybody else is on the east coast, nobody in Nevada that I could find.

Another option would be a new Acer head, http://www.aceronline.net/acergroup/em-3vk.htm They sell the head seperately. About $4500 if I recall correctly, but don't quote me on that. If I were going to replace my head, this is the way I would go.

There are several ways to mount the router, some will depend on the size of your router.
Here is just one example.

Thanks,
That photo gives me the basic idea on what to do.

I would think 3/4" to 1" thick alum would work,
with the double supports??

Thanks for that info,
I have an email sent to them.

I would settle for anything in the West half of the US,
just to keep the shipping down.

If you go with 2 supports, 1/2" would be sufficient about 1-1/2" apart. For a 1 piece mount I would go with 1-1/4. I went with 1-1/4" on my router mount on my duplicator because it was easier to make it swivel.
