I need a little help with a jointer I found at a local industrial auction. It is an import (Taiwan) but very clean. I don't think it is very old. It is medium olive green and the id tag reads; Northwood (in red letters) It is labeled model CT-150D and it is a six inch. Its a one horse and has the cabinet style base. I have already tried it out on some cedar 1x6 I had laying around and it cut great. I'm sure it will be more than adequate to get tops and backs ready to join and I want to get new knives/blades for it but I can't find any info on it so far. I can post a pic if needed. Anyone have any info for me?

Joe,
Do not use that on your tops and backs! It will destroy them.

Jointing the edge of top/back plates on a power jointer works just fine.
Now, if the OP had suggested putting backs through a thickness planer....

Joe-
There are a lot of machines out there with different nameplates, but most of them are knockoffs of Delta/Rockwell machines, made in Taiwan.
Unless the blades are quite unusual, you can probably find replacements by just using the dimensions of your existing blades.
If you use a sharpening service, a question to them might get you results quickly.

Cheers
John

Joe, I did a Google search on Northwood Jointer, and got a link to what was, apparently, one of Northwood Tools' more popular items, a 6" jointer.  They are an Australian Tool Company, and still have a website, but I couldn't find a jointer on the site.  Probably something they had in the past, that they had their name put on.  I noticed, that another site was selling blades that would fit Grizzly and Northwood jointers.  Apparently they also have a Store in the US now too.  Maybe they would have some answers for you.

Thanks guys! I messed around with it a little more and found that the old owners had the fence set up in such a way that the first one inch of the 6 inch blades weren't ever used. I set it up to make use of that and got a very clean and precise cut. I also removed one of the blades and measured so I can find replacements. Wouldn't sharpening these be pretty tricky? seems that they would have to be pretty accurate from one blade to the next. I do have a lot of Amish craftsmen and sharpening services in my area, maybe I could give that a try?


Steve, you really mean not to use a jointer to create a clean and straight edge to join the two sides of a back or top? I thought this was an acceptable ( and controversial?) method?

Joe-
You should be able to get several sharpenings out of a set of jointer blades- replacing them isn't necessary very often.
I just keep a second (sharp) set on hand and swap them out when needed.
Some jointers let you shift the blades sideways a bit; this can be handy if you get a 'nick' in the blades- shift one and you can get a reasonably smooth cut until you swap out the set.
There are also techniques/jigs for honing blades yourself, but I usually just get them sharpened professionally.

If you ask some of the local craftsmen, they should steer you to a good sharpening service.
Some of the 'sharpening' services can't be trusted with anything but lawnmower blades.
I found a bunch of CT-150 jointers on the web-perhaps like yours- they look like nice machines. I think the CT refers to the company in China that makes them.

Cheers
John

Evidently some are successful at doing that. That's great and perhaps you will be good at it.
I use a shooting board and block plane.
I have a nice 6" jointer and I wouldn't use it for that.
I'm not saying I'm right and they are wrong.
There are many ways to do it. Some use a straight block with sandpaper and are very successful. I think I saw one gut using a table saw.

if i was to choose between using a block plane or my jointer to join plates i would take the jointer any day. whilst i did try it once with a block plane it found it too short. the shortest plane i've been pleased with for the purpose was a no 4 smooth with the iron honed square, but my favourite is a no 5 jack. some prefer to use 6's and 7's. even read about a chap who used a no 8.
