Default My Table Saw Crosscut Fence Project

General-
Been asking about parts of this here in different threads. Now I'm getting ready to put this together. This will follow up from planning to construction. In the meantime, I plan to do some review type info to help others weed through some of the things I learned along the way on this.


Background-
I am planning on buying a European Sliding Half-Table Cabinet Saw... My dream. My Goal. Been saving for a long while, but partial funding for that is also hinged on back-pay from the VA. Still waiting. Still saving. Thought maybe sooner, but being patient.

Work goes on. In the meantime, I have a 40+ year old Rockwell Shop Saw. I have 2 miter slots to the Left and 1 miter slot to the Right. Been getting by with it, adding on the left and right extension tables, infeed and outfeed tables with miter slot extensions and an assorted regiment of table saw sleds and table saw jigs.

Wanted to add function by building a Crosscut Fence, closer to something that would be on what I am shooting for in my dream saw, but have whatever I build, re-usable on that saw when I get it.


Requirements:
- Will replicate a sliding table, without having to spend money I don't have to buy an accessory sliding table.
- Implies that this must be affordable.
- Most be accurate and be able to provide precision results.
- Must be able to hang jigs I have and use.
- Most be able to use material stops and have an adjustable scale to be able to set those material stops.
- Must be strong and have little fence flex.
- Must be able to do accurate miters.
- Must have some type of material hold-downs, with a quick-release/clamp type of arrangement.
- Must be adaptable.
- Must be easy to use.
- Must be able to put on saw or take off at a moments notice, but remain zeroed and square to be ready for use when needed.


Continuing-
Sounds ambitious doesn't it? Let's see how this goes.


Materials collected so far-
- 4 foot Aluminum Extrusion, 1530 series, HD? I don't know just how to describe this. Got this from a friend who salvaged this from a ceiling joust framework that supported very heavy medical diagnostics equipment. It is very heavy-walled, precision and true. Machinist straight.

- Craftsman Digital Miter Gauge, 320.29939. I've had this a while and I love it. Will review this here later.

- Delta 36-946 Heavy Duty Precision Miter Gauge. Will review this here later. Is a rebranded Osborne along the lines of the Osborne EB-3 and Dewalt DW7470. There are minor differences between them. I will review this here, the reasons I chose this and describe the branding differences.

- Incra 48" T-Track Plus with adjustable scale.

- Assort t-nuts, t-bolts, alternative fittings, assorted scraps and such.


Continuing-
I have to pace myself with this... Time, rotating shift work and other responsibilities. Money, major goal is to save for my saw. Trying not to spend too much, that would detract from my goals.

Will try to post pictures.

Thought of just doing this as an article. But I like how your feedback helps me get things worked out when things get rough or sidetracked.

Am going to reserve some of the next posts to continue this, organize it and keep things together. That way I can post as it comes together. But also keep it upfront and together for others coming in to this later down the road.

Miter Gauges.


Craftsman Digital Miter Gauge, 320.29939.

Mario and Tia Salazar invented and hold the patent on this precision digital miter gauge. At the 2006 International Woodworking Machine & Furniture Supply Fair, Salazar’s digital instrument was being displayed. The miter gauge caught the eye of a supplier of the Sears and Craftsman line of tools. They entered into a licensing and royalty agreement together.

This miter gauge has been reviewed with praise from Woodworkers' Journal, Wood magazine, American Woodworker and Popular Mechanics. Popular Mechanics gave the digital miter gauge an Editor's Choice Award.

I think this miter gauge, even though praised, is under-rated. Sad, but as far as I know, the inventor's licensing upfront money and 8% royalties have yet to recoup their initial investment.

I love it. More accurate than I could ever want. Accurate to 0.1 degree, which I tend to get near and leave at that as acceptable. I don't make parts for rockets, but I do want accuracy to be there. It accepts 80/20 styled 10 series aluminum extrusions without any modifications or adapters. It came with a 15-1/4" aluminum 1020 fence. I usually use it with a 1020 36" or 48" fence. The miter bar is adjustable to snug into miter slots. It zeroes easily.

It comes with an accessory extrusion that makes it double as an accurate digital blade bevel gauge. This requires taking off the blade insert to do this. i find the Wixey or Cen-Tech Digital Angle Gauge easier and faster to use than this gauge for that purpose as those don't require you to remove the blade insert. (Note on the Cen-Tech- Glue the magnets to the base of the gauge before using. It's low cost must have been from cutting back on things like glue-cost. Otherwise a great gauge.)

I got this gauge at $30 from a local Sears store who was clearing their shelves and had it on closeout. I got more value in that purchase than I had imagined. If I had the chance to buy another (even used) at that price, I would jump on it without thinking twice and consider myself blessed!!! Even at it's regular price... It's a good deal.



Delta 36-946 Heavy Duty Precision Miter Gauge.
This is a rebranded Osborne along the lines of the Osborne EB-3 and Dewalt DW7470. It is not as polished as the Osborne EB-3, but has a few pluses over the Dewalt DW7470. All three use the same tri-braced miter mechanism and basic Osborne fence extrusion. Regularly, the standard retail pricing is that same for all three(!?!), but they have differences.

Osborne Miter gauge owner's here had good things to say about their miter gauges and are very loyal to this product. The Osborne EB-3 is a finished quality compared to it's 2 rebranded products (Delta and Dewalt). All the bells and whistles. The EB-2 includes a stuck-on measuring tape scale, a fence that extends from 24 to 31", a stick on sand paper face, a sliding adjustable stop, a tall user handle, A shinny adjustable miter bar.

The Dewalt DW7470 has the basic 24" fence extrusion without the fence extension. It uses the same black miter bar as the Delta (described below). There is no measuring scale for the fence. No sand paper. It has a short user handle.

The Delta 36-946 is that same as the Dewalt plus a quick release, heavy duty material hold-down clamp. Like the Dewalt, it has has a miter bar that includes a boss for mounting that hold-down clamp.

Rockler had it on sale at 50% off...

In another thread, I asked about Incra and Osborne head-to-fence measurements, from the table to the slot... To see which , if any aluminum extrusions they would fit.

Incra was 1-1/4". Osborne was 3/4"

Incra fence mounting bolts holes in their head's are a vertical slot. Their fence-to-head mounting t-slots center at 1-1/4". All their fence extrusions fit all their heads. They are interchangeable. From their "pictures" (not verified yet by owners), I figured those slots might extend up to 1-1/2"... or with a little mod'ing they might. Important to this measurement, is that that is where the center of the second slot up for a 10 series aluminum extrusion... If so then any Incra miter head could mount to a 10 series extrusion with very little modifications.

Osborne styled fence mounting holes are just that. They center at 3/4" from the bottom of the fence to the center of the extrusion t-slot. This is a "good-news" kind of measurement. Why is this good-news? Well, the only bad thing people had mentioned about the Osborne styled fences is that the stock fence extrusion has nothing on it to be able to mount a sacrificial face or to be able to mount jigs, such as for making finger joints... With that 3/4" mounting hole, the Osborne styled miter heads can mount directly to any 15 series extrusion without any modifications.

I guess I should say something here about aluminum extrusion slot measurements. On 10 series extrusions the first slot up from the corner is 1/2" to the center of the slot. All slots up from that are an additional 1" from center to center. On 15 series extrusions the first slot up from the corner is 3/4" to the center of the slot. Each Slot up from that is an additional 1-1/2" from center to center. These measurements are handy if you plan to make things with aluminum extrusions.

On to assembly-

The Delta Fence Mounts directly to the 15 series extrusion, if you use different bolts and nuts. The hold-down clamp is tall enough and long enough to reach over a 1530 extrusion.

My digital miter fence has it's mounting holes 1-1/2" from the bottom of the fence to the mounting bolt holes. The first slot up from a 1530 extrusion is 3/4" up. The second extrusion up from a 1530 is 2-1/4" up. The holes don't mate up yet. I need to make an adapter plate to mate it to the extrusion. I figured I'd make a prototype out of wood. That way if it needs to be changed... Then later make one out of aluminum plate.
