How to check out a used Delta Uni?

[Ron Kanter]

Found an older Delta Unisaw for a reasonable price.
What should I look for when checking it out? It is an older cast iron base machine. That is very appealing, but I don't want to buy a project when I am looking to buy a tool to use on projects.

Any advice or referral to other other threads would be appreciated.

I found a thread on buying a used uni. It had lots of helpful comments and one suggestion that I need more guidance on. One poster suggested that " things that are not so easily repaired are deep wear marks from repetitive ripping, and wear on the elevation and tilt racks."

I get the deep wear marks, but what and where are the elevation and tilt racks?. If you can include a picture that would be super.
Thanks in advance,
Ron

Hi Ron, the mechanisms are rack and pinion assemblies.

The pinion is a small gear that goes on the elevation/tilt handwheel shaft.

The racks are the large partial gears that tilt or elevate the saw blade.

Check for worn, chipped or missing teeth.............regards, Rod.

Google "Saw Center".
They have lots of good Unisaw info.
