Extension Table with a T-Track

[wdelliott]

Dusty,
This relates to my inquiry a bit earlier on the other feed. Could you elaborate on the parts (and parts number if convenient) for the longer T Track?

I did not realize that SS sells the longer t track. Also, how did you attached the T Track? Is there a fence underneath it?

Thanks.

Shopsmith has two different T-Tracks that might serve your purpose.

555897 which is 23 3/4" long and

515494 which is 29 11/16" long. (status is "May be on back order or built to order")

I will go into some additional detail on how I mounted this to the table. After the original project I had some problems which were resolved. I'll post that (to this thread) some.

PS 10/17/09

When I initially attached the t-track to the extension table, I had to use washers as spacers to get a smooth interface. The edge of the table was rough; caused by materials left after the casting process. I just got around to fixing that. Using the conical disk, I smoothed the edges of the table taking care to keep it straight and perpendicular to the front of the table (the bosses). Remember that eventually (in use) it shall become important that the track be parallel to the tracks on the main table (the blade).

If you do this, be patient and careful. Take a very small amount of material with each pass. I did not, to begin with, and the disk just about took the table right out of my hands to throw at me.

That done, I simply reattached the miter track assembly that I had created earlier and realigned the table. I measured just a while ago and found that after several reconfigurations of the Mark V I have lost a little of the initial parallelism of the tracks. The extension table is 1/32" off which I don't think would ever cause a problem. Initially, I had then within .006" of being perfectly parallel.

Dusty,
In a lot of cases, justified, but in this case not so. After all we are talking about extruded aluminum t-tracks here. Not machinery.

or footwear.
I'm wearing a pair of New Balance sneakers which I bought because I saw "MADE IN USA" inside 'em. After I wore them a while-- a short while-- and pieces started falling off I looked closer and saw "MADE IN USA from imported materials".
Three guesses...

Just unwrapped and inventoried my new "Lift-Assist".
One label on the upper mount= "Made in China".
I'm afraid to look at the high-pressure gas cylinder.

Yeah then there is a USA manufacturer of a rather interesting square sold by one of the woodworker outlets. My wife saw one and decided it would be a neat Birthday gift. Yes sir made in the ole USA, It wasn't made in China so couldn't possibly be anything but terrific. Terrific in every respect other than the plating begins peeling of before a fellow even unpacks it. Now the vendor has been really good about replacing them. number three was picked up by our local mail delivery lady today. I guess poor quality can happen anywhere. fjimp:(

Maybe that 'plating' is just a protective coating to prevent shipping damage?

I wish that were the case. Underneath the plating is rusty Steel.

Sneakers? Lift Assist? Rusty Parts? Defective Plating? Made in China?

Not my extension table or its t-track! They are made of aluminum and were assembled in my shop!

Base steel - Melted from recycled steel.....made in China and imported.
Cleaning and plating solutions - Reclaimed and repurified from disposed chemicals..... made in China.
Plating metal - Recycled zinc from sacrificial ship anodes that no longer function..... made in China.
Packaging materials - Recycled materials from overseas junk yard salvage which outgas formaldehyde, chlorine, and trichlorethylene.... made in China.Did the US manufacture stand a chance??
