technics SP-25 armboard

I need to a adapt an Audioquest PT-5 tonearm to a Technics SP-25 turntable base. The round hole is pre-cut to 5 1/2" in diameter and 3/4" deep on the table base. I could buy the official, original armboard but it is designed especially for the EPA-500 tonearm assembly and would need to be adapted for the Audioquest arm. It might be cheaper to build one from scratch with all the correct measurements. Any suggestion will be appreciated.

Hi Stanwal:
The official Technics armboard is the black pre-drilled EPA-B500.
I have one installed in a SL-1015 with the EPA-A501H straight titanium tonearm and stem. It is a great arm but seems to be designed for light weight cartridges only as my Rondo Blue is too heavy. I currently have a Denon DL-160 mounted on it and it sounds great.
Rather than try to adapt the official Technics armboard for the SP-25, it may be easier to custom build an armboard out of maple or oak and use the EPA-B500 as a template for the outer dimensions and mounting holes only and position the stem hole to accept the Audioquest PT-5 arm.

Hey guys...thanks for all your suggestions! I solved all my problems by throwing more money at it. I broke down and purchased a used Technics EPA-B500 arm base with an EPA-250 tonearm from an analogue specialist based in Hong Kong. This arm is an "S" shaped and features a removable headshell (great for cartridge changing). I was able to sell my Audioquest PT-5 on ebay for a nice profit helping defray the cost of the Technics arm. Listening as I type this and it sounds great. Nothing like the real thing!
