Dusty,
Thank you sir for another great idea. Now all I need is the aluminum angle iron and some time to play. I recently built a 6' long dolly to move my Shopsmith tools and work bench's with. It was a challange doing those long cross cuts. The extra T track will answer that very well. When I stocked up on extra T tracks and other assorted shopsmith parts my loving wife gave me one of those sideways looks. When I finish building your great idea she will begin to see a tiny bit of madness in my spending. Thanks again.

Jim

Looks great Dusty!
I can't make out how you attached the T Track to the floating tables.
And is this the 23-3/4 T-Track that SS is now selling?
Also what is the longer miter bar? SS is showing a steel miter bar #555895 and two Miter Gauge bars 516525 for the 500 (which appears longer in the picture) and 516619 for the 510/520.
Thanks, Hawk

I had to use two mitre slots on my router table, what is the number of a longer mitre slot?

hawk,
The t-track that I used was 30" long and has five (5) mounting holes. I think the part # is 515494, based on old receipts.
The miter bars are 516619/ I notice that these are on sale.

Yes, the T-Track is still listed on the site, so I'll call and ask.
But how are you attaching the track to the floating tables?

hawk,
I probably need to include some photos but for now I'll answer your question as best I can.
What you have seen so far was held together with small "C-clamps".
Originally, I intended to drill holes for four or five bolts with thumb nuts. When I got ready to do that, I became aware that the edges of my tables (all of them) are not straight. When I put a straight edge against them it became apparent that the castings are very wavey.
I don't want to put localized stress on those castings for free of cracking them. I have one that is cracked already (not caused by this).
When I attached the c-clamps I was careful not to locate a clamp where there was space between the aluminum rail and the casting. I did insert some washers to act as spacers where I felt I had no choice.
I plan to reassemble using two sided tape. I don't know just how much force will be required to hold this rail assembly in place. The tape just may do it. Vertical movement is the the only concern. Laterally, I slide a floating table up against the assembly so there will no movement in that plane.
I guess they call this design correction. Another word for kludge.

Kludge is good!
Clamps is good!:D
Whatever it takes to get the job done!
Thanks, Hawk

I hope the images will tell the story. If not, ask.

Dusty,
I'm not quite understanding how to attach the T-Track to the tables. Could you explain? Thanks.
