Today in the shop (Another oh no! Shopsmith v120 Miter Gauge Adapter Plate

[reible]

A while back I picked one of these up, yes, even before I had the V120 miter gauge.

So I now have a V120 so I dug out my adapter plate to see how it works. Sorry it doesn't!

First off it sounds like something that I could use, I have a lot of homemade jigs and parts that mount to the old shopsmith miter gauge. I didn't even get to them as the very first thing I tried didn't work. Some odd thing I built? No, something that I got from shopsmith.... The old hardwood miter gauge extension.

So lets start with some pictures.

So far so good.

Again looking good, the two are now attached.

Now things start going wrong. The hardwood extension bolts can not go where they should....

Lets ignore the elephant in the room and keep going. So now I can get the the screws to show up at the back. Never mind that the nuts are going to only have a little dab of metal to hold on to....

More to come.

Just so you get the full picture, here is a picture of the parts put together.

Oh yea you also have to deal with the extension now being up off the table.

Now it could be I'm not understand how this should work, so please help me out here.

I would have to give this a bl-aha or how ever that is spelled.

Maybe someone else with one of these adapters on a v120 and will pipe up and surprise me, but it seems pretty clear that they don't play nice together.

The work around would be to drill a new set of holes at the other end of the hardwood extension fence spaced use the outer (longer) slots in the adaptor plate and move the bolts to the new holes.

[joshh]

I'll bet the wood extension was designed in the era before the adapter plate or the incra gauge. I do think you could flip it around, and use longer bolts.

Does anyone know if the aluminum extensions (shown here) have the same problem?

[BuckeyeDennis]

So I've been seeing Incra ads and promos or a while now, and they seem to have a solid reputation. I like the nice extruded Incra fences. But the miter gage always had me puzzled. The SS gage has a nice thick aluminum casting, with the surfaces that matter machined, presumably with precision. The way that God intended it .

The Incra miter gage is a basically piece of cut and formed sheet metal. In the old days, that was an adequate, low-cost solution. Until the recent threads, I had assumed that Incra had somehow elevated sheet-metal forming to a higher level of precision. But with all the tuning going on, now I must wonder. Why, again, is the Incra miter gage better than my nice cast and machined SS gage?

Edit: "It's a lot shinier!" is not an acceptable answer.

On E, you should expect a similar problem as the holes are drilled with the same spacing for the original miter gauge.



On F, you should be fine because the mounting bolts fit into a slot in the back of the extrusion and you should be able to use the outer holes on the Incra adapter to receive them.

"No need to modify your fixtures... or drill holes / cut slots into the steel face of your new Incra v120 Miter Gauge. Just attach the threaded adapter plate to your gauge face through the existing face holes, using the included hardware. Once the precision machined, high-tensile polymer adapter plate is mounted, you can quickly and easily attach your fixtures -- or any Shopsmith miter gauge mounted accessories -- by simply dropping their mounting bolts into the open-top slots... just as you were accustomed to doing with your original Shopsmith miter gauge."


Somebody either lied or doesn't have a clue!:rolleyes:

I don't have this accessory, but "E" looks like the holes are up higher from the saw-table, and should work. A homemade wood fence could be made this way, too, but you'd have to accustom yourself to flipping it around the 'yaw' direction rather than the 'pitch' direction when you change miter slots.

If they were higher, they would not work with the ss miter gauge.


The miter gauge extension has the holes centered top to bottom. When changing slots, the extension is flipped making what was the top the bottom. The mounting bolts are counter sunk into the face so it needs to remain 'the face'. To me that motion is a 'roll'. Changing the angle would be a 'yaw'.
