I have a Harbor Freight Heavy Duty Flexible Shaft Grinder/Carver on order and am planning to build a router base for it like the one Shipwright built here.

I have a couple questions that I hope someone here can answer.
1. I’d like to work up the dimensions of the base. What is the the diameter of the hand piece?
2. I also want to order some router bits for inlay work. What is the size range of the chuck?

Diameter of the hand piece = 63/64” with a micrometer (The thickness of a piece of paper under 1”)
Chuck capacity = 5/32”

Dremel router bits fit fine. Drill a 1” hole for the handpiece and then cut the (wood) piece in half. The kerf removed will allow you to clamp the handpiece tightly.

Thanks. You never know when Harbor Freight will change stuff, but I took a chance on it fitting and went ahead and made the pieces.

I am anxious to get the HF order, but I’ll have to wait until it arrives. I can’t begin to count all the little jobs where this setup would have been super handy in my luthier work and I am anxious to try using it for inlay work.

I came close to springing for the Fordham tool and the Stewart MacDonald router base, but the price is pretty steep (~$400 vs about $40 and some stuff I already had around with a 25% off super coupon for this setup). This setup will be cheap enough that if I wind up still wanting the Fordham/Stewmac setup, I can chalk it up to experience and not have any regrets. That said I really expect this tool will be plenty adequate and besides I can envision possibly wanting to have more than one set up for different functions, since I often am working in a semi production environment.

On a related note…
Anyone have suggestions on a source for 1/8” shaft up cut and down cut spiral router bits between 1/16” and 3/16” or so. Stewart MacDonald has a nice selection of down cut but they are a little pricey. Are there cheaper sources that have decent quality? It seems a bit high to pay $20 for a 1/8” bit. I’d buy a set of various bits to have a variety of functions, but for these bits individual bits may make more sense for my needs.

I was surprised just how poor the selection was at the local Lowes.

My HF flexible shaft grinder finally arrived. I was happy to find it fit the router base that I made for it just fine.

I ran it a little and it seems like a nice tool. I guess time will tell how well it holds up but for my first testing it works well for the sort of routing I plan to use it for. It seems to have plenty of torque and the variable speed foot control woks well. I am very happy with it so far and can think of a million little jobs it will be hand for. So far I just have the small dremel set of router bits and some other dremel stuff that fits it.

Have your say...
