Background:

In Jul 2012 I purchased a 150mm or 6” Jointer from Hare & Forbes

Why is it called a Jointer? well it partly prepares timber for jointing, along with its team mate the Thicknesser
another odd name as a thicknesser actually makes timber thinner!

This jointer has what seems to be a series of look a likes and re badged relatives :-
Jet JJ6, Grizzly GO490x Hare & Forbes PT6 and a Carba Tec JN 150c.
All are fundamentally the same in regard to jointing however legs and cabinets may be different.
The jointer has a primary job of flattening one edge and one surface, and then its job is done.
Well not quite it can do a series of other tasks
1. Rabbeting, not that I do a lot in Queensland as rabbits are prohibited animals, (don’t mention the cane toads)
2. Making Octagonal shapes
3. Making Tapered legs
4. Trimming your finger nails or fingers quick as a flash. (just check with Sam Maloof)

To complete the job after one side and one surface is done the thicknesser is then used to obtain the exact thickness of the timber you need, closely followed by the table saw to obtain parallel edges and we are at last finished and ready to use the timber.
It requires a special check of the timber for, grain direction and also cupping and bowing.

A few basic considerations are needed though before introducing timber to the Jointer.

1 Grain direction
The general rule is joint with the grain (See 3)

2. Cupping and bowing

2. cupping and bowing should be facing the cutter for the first cut.

3. Considerations for end grain jointing. Now to suggest end grain jointing sounds like a plan for disaster, however using some skills it can be done
Introduce the end grain and make a small short pass then reverse the timber and continue taking care to hold the material firmly on the outfeed table.

The upgrade:-

After returning home and being traumatised by my little mate the turtle having done a runner I decided as therapy to buy a spiral cutter head for my jointer.

I purchased it from Hare and Forbes fully understanding the jointer i have has since been superseeded and no longer available but is a exact model of the current PT6.

The spiral head cost about $ 500 AUD and I bought spare index cutter for another $77 AUD so this has almost doubled the cost of my Jointer as its purchase price was about $500 AUD.

Who makes the cutter? ...CTS do…that being Cater Tool Supplies

How I did it:-

Rolled out the unit ensured it was powered down and un pluged it.

I then removed the dust port backed the in and out feed tables off.
removed the fence and associated parts.
Disconnected the drive belt.

Under the Jointer and out of sight are three bolts holding the Jointer onto the cabinet.

I removed these, along with both cranks on the table height adjusting wheels.

Then with the use of a second table tilted the jointer over on its side.

Next using the gear puller removed the drive pulley and undid the two bearing mounting bolts.

Using a gear puller I removed the bearing mounts and then with a rubber hammer reinstalled the bearing mounts on the new spiral cutter.

Reassembled all the parts basically the reverse of the dismantle procedure.

The whole process took about 2 hours to complete.

The jointer was manually spun for any unusual noises (bumping and grinding) and then the drive belt refitted and powered up for a second noise check.

All was good so I spent the remainder of the afternoon preparing timber and continued on Sunday without drawing the crabs from other homes.

Conclusion:-
An amazing up grade in finish, ease of use and a massive reduction in noise resulted.
Is it cost effective? I personally would have to say yes it is.
Mainly because of the above and along with the laborious time consuming activity of changing three blades and getting them all set parallel across the tables.

Try not to notice the new cutter some how transported itself into the Jointer at the first image!

The spiral cutterhead will make a difference in long term use but I’m betting you already know that

welcome to the club rc i did mine last year,it’s the only way to go as far as quality of cut and yes noise reduction.i wanna do my 15” planer too but from what ive read a much bigger job.

i assume this operation was, ”duck” approved ?

Pottzy,

I had reservations in regard to posting this activity as its not something that has never been done before and didn’t want to bore everybody with repeat processes.
But while I was discussing nuts with LBD he was of the opinion I should do it anyway and if anybody was interested they would read it, so here it is.

I should get some before and after shots showing the results,

BTW the dust port flange has after market nutserts in the cabinet, a bit hard to see but they are there.

Having a Jet Combo with the helix, I was a tad more concerned about that poor tutel...

However, on behalf of those struggling to make up their minds for an upgrade and dig their hands into their lobster pot wallets (money goes in, but doesn’t come out), I thank you…
The more coverage members provide, the more informative this forum becomes…

Well done… for a cane-toad farmer.

Wuz gonna abuse shit out of you about the sideways photo², but then realised, from your explanation, that it was tilted.

Whats with that brown blood streaks? Did you sacrifice a few cannies to your gods on that table when they let you back into the state?

PS. I wasn’t interested, so I didn’t read it… as I advised.

For the man who has everything !!

The brown skid marks.

Before I go away all my WW tools get preserved with MX4 before I leave, and after every use also actually
Being a poor no income person I cannot afford to leave my jointer out in the yard like some people.
In fact I look after my gear better than Mark Wilsons dogs.

You may have noticed the all have the bare cast iron surfaces look almost as good as a show room model.

Sideways

legend has it the anatomy of some human species is actually sideways, my Dad told me about it when I was very young, I am yet to confirm this is actually correct but there is no place for it on LJs.

And BTW its turtle if you mind !

Some promised “Before and After” shots

Nothing to see here actually or that’s what it looks like.

Hey HOTP

The long piece I am going to turn into some dentil, that might give you something to get your teeth into.

Duck... and I don’t mean bob (and I’m not using your name in vane) your head, who has everything!

The brown skid marks…

Just reminded me of non-lumber jocks.

For this duck, it’s after a cask or two of vino.

And BTW its turtle if you mind !

Go ask your TUTEL what he wants to be called… other than for a mellon. Wot… you can’t… can’t be found?
