Can you send some pictures? And what bits do you use?
I bought a used radial arm saw and the chain mortise attachment and was thinking about removing the post, arm and saw from the table to rig up some sort of portable unit but then I thought about the wright of that and all the constant adjusting and resetting and I just can't see this idea getting easier.
So I like the idea of some alternative home fabricated rig. Had you thought about building a plunge rack assembly with similar to what the big money buys but using a small electric chainsaw?
Let me know if you can send photos of your creation.
Thanks,
Terry
