A little Help please!

Postby robertyb » Sat Aug 12, 2017 11:37 am

I just mounted one of the Trophy Ridge 525 scopes on an original 2 stage Trigger Tech mount and can't get it quite back far enough for proper eye relief. I have one more space on the back of the mount but no cut outs in the middle to seat the rings in. Thus, I need to cut out a new slot on the TT mount.
What is the best way to go about this. I am not very good with tools at all but I do have a few files around I can use. Might be able to borrow a dremel tool also if needed.

I would scribe a couple of lines where you want your slots and then cut the aluminum with a hack saw as if you're cutting a dado in a 2X4 with a circular saw. Then dress the bottom of the slot with a coarse file.

Alternatively, bring it to a machine shop to have the slot milled.

I started a slot with a fine triangle file (using the point) then went to a small round file for the depth .The thru bolt is round so it fits good at the bottom of the slot.just take your time.

And then clamp a block onto the base to use as a guide for your file. Go ahead and spend a few bucks and buy a new file. That way you can pick width that is correct and it will work faster as well .

You might need a file card or fine wire brush while you're at it. Aluminum has a nasty habit of filling a file up.

I did an extra slot on an aluminum Weaver rail with a table saw and carbide tipped blade. Width was perfect and it came out extremely smooth in about 5 minutes total. Just set your depth where you need it and clamp it in a small vice that you use against the fence. I bet you could screw it to a board to use as a guide against the fence if you don't have a small machinist vice.

It turns out that I do not need another slot. When I put this short scope on I tried to use my regular low rings which would not work so I used the high rings that came with the scope and was getting what seemed to be parallax distortion from insufficient eye relief. I have a Munch mount on this bow and it turns out that the small black screw cap nuts which hold the quiver mount in place were partially blocking the scopes view causing the distortion. I removed them and the scope cleared up and I can get by with the current eye relief. I ditched the cap style nuts and put small washers under the bolts to raise them a little and used regular flat nuts to tighten back down. It worked and I now have a clear view.
Thanks for the suggestions guys as they might come in handy later.
