Topic tags/keywords: rockwell jointer

I found this machine on CL today. The seller wants $1000. Does anyone know which model this is and how much it’s worth? The seller claims it works and the knives are dull. What are the holes in the outfeed table for? Also: can it be converted to spiral head?

Since it’s US made, surf over to and look around.
There were many derivations of ‘Rockwell’ equipment, and that site would have largest resource to help.
Looks similar to this 37-315:

Best Luck.

PS – A new 8” jointer is only $1150 @ Grizzly. That used tool is overpriced, IMHO. Would sell for at most $600-$750 around here. The Grizzly 8” with spiral head is on sale till tomorrow.

I don’t know but I just saw that listing this morning. Looks interesting but maybe a little high as CaptainKlutz said.

It’s $500 too high. And that’s if it is near brand new

Thats the same machine as you see here under all that dust and dirt.

I started the rebuild a couple of years ago, got pulled away on a family emergency half way through and haven’t got back at it since, this year, I need it for the sawmill. I paid $270 at auction because it had a 3 phase motor and hadn’t been used in years so the rust was deep. Its cleaned and painted up to the edges of the tables and there is a 1.5 hp single phase ready to go in.

The threads in the table are for mounting a knife grinding accessory, which I have. Here is a picture of the grinding head, it mounts in a cast iron and slide tube assembly which bolts to the table. The one I have has a 20” capacity, So I am thinking of setting it up on its own base so I can do both jointer and planer knives on it.

As CaptainKlutz stated $1000 is way to high for a well used machine, even if it is a Rockwell/Delta. I would haggle for an end price between 5 and $600, which when I add the price of the new motor paint and time is where I will be.

If the spiral head is the same length and width as the regular head and it fits in the original bearings it should be ok. Bring your old head into the supplier and compare it to the spiral head. With all the knives in, it should be the same diameter at the knives edge as the original or you may not be able to adjust the tables for clearance. Theres a nasty article in FW that I posted on my blog about what could happen if the clearance isn’t there.

Have your say...
