My Prema Typ 02 shaper

[Trion]

I can only guess they were exported to the scandinavian countries and possibly other parts of north western europe.
From what I have heard, Prema and Sajo machines are still very popular in Sweeden, with quite a few still in use. Here in Norway the machining industry is mainly supplying the oil industy, so no place for old mills and shapers there

Cidrontmg: My Sajo mill was made in 1974 (err, I meant 1971). No idea when the shaper was made.

[Trion]

Small update. I snook out one evening after having studied the whole day for my coming exam, and got some actual work done!

Cleaned all the remaining parts that need to be painted


Quite a few..


And started sanding down the main door


While sanding down the letters I got some ideas. The background paint around the label has obviously been red at one time, and I'm thinking I'll paint it the same. But wouldn't it look nice with shiny letters painted with clear paint? Or am I just being fuzzy?

[AndreasL]

Afraid I can't help you regarding sources for parts etc more then what I already mentioned in my PM.

Din Maskin in Värnamo is the official supplier of Sajo-parts in these days I think.

One can also check out www.industritorget.se for spares etc. From that web site you find links to most every company doing business with machines and parts. Many (most?) of them located in Värnamo or nearby. Prices tend to differ though and adverted level maybe set a bit to the high end.

As to when the "hay days" of machine production in Värnamo took place I am not 100% sure, but at least from the -50: s to -late -80: s this business was big. Really big, I think.

Only downside about these brands if sought for in Sweden may bee there reputation as sturdy, accurate and "atom bomb proof" = you got to pay if the seller knows what he or she is selling. But when the iron is well in you’re shop, you have big chances that the machine will outlive a generation or two if given some TLC every now and then. ;)

@ The Prema sine I think you should paint it all red and then sand down the letters and frame to let it stand out. Yes I know, it may be a bit extreme, but having the opportunity and all, it’s nice to have nice locking stuff. 


Good luck at the exams! I'm 200% sure you doing the right thing taking some time to clear your head. Remembers me about the few times applying this method my self. Worked much better then trying to force information, 24/7, to an already full hard drive the last days befor a big exam. 

[Artie]

Hi again, witht reference to this quote "Or am I just being fuzzy?", this is YOUR machine.... I think you should be as 'fuzzy' as you want to be... 

[Trion]

I looked at industritorget. Prices are similar to bay prices elsewhere in europe. Thanks for the tip!

Will see what I deicide upon regarding the door emblem, it´s gonna be a bit extra work polishing the letters and painting them with clear paint to avoid rusting. But then again, it will look nice

But today I also spent the evening in the shop, now almost all parts have got their first coat of grey paint. I can probably make the second application this weekend, and finally start the assembly of the machine again

[slowcoach]

Hi Trion, Great looking machine  , Did you use any type of undercoat before painting the machine? I ask because i'm thinking of painting my little shaper (alba 10"), the paint I have is a floor paint (Johnstone's grey) which I believe will be ok to use.

Excellent thread by the way

Try Bondaprimer. Sticks to damn near anything, including aluminium. ... and fingers ...

[slowcoach]

Hi Dave

Bondaprimer, Is that availible at say Halford or specialist paint suppliers?

Cheers
Rob

[Bluechip]

Rob

Used to get it at Halfords, dunno now ...

Frost Auto Restoration may have it ..

Not in the sheds generally, but try a search online..

Dave BC

EDIT  Two guesses ... and neither have it ... story of my life .. however, first off the net at random

http://www.marinemegastore.com/product-product-AQU_Q05167.htm

So it does exist ..

If you want some, you could try some of the 'privateer' car accessory shops.

Better bet than the likes of Halfords for owt useful. But then Mothercare would be ... 

Cannot remember any time in the last 20 yrs. I've gone into any multi, and found what I want ... useless .. grump, grump, grump ... etc

Before painting, I only washed with ethanol and sanded the surfaces roughly. The paint I use is a one component cheap machine paint, same brand as I used on the head on the Sajo mill.

Now all the parts have gotten a first coat of paint. Still waiting for them to dry, in my -4deg. celsius shop


Painted the inside of the table as well


Door


Ram


Covers etc.


And some more covers


I also bought myself a pair of new belts for the shaper, as the old one was pretty worn!


I hope to make the first chips sometime by christmas

[Darren]

Crikey, are you getting the paint to dry at -4C?

I'm having trouble here at 1 or 2C with my car bits, had to leave it for now till it warms up a bit.


Love the thread (as always) ... 

[Trion]

Was just out in the shop applying the second layer. It was still -4 when I got there, but I let a heating gun heat the shaper casting for about an hour, until most of it was comfortably warm. Paint should be dry by the weekend

Glad you enjoy the read

[slowcoach]

cheers dave, Buurrrr -4 

[Trion]

Apparently paint dries at minus 5 too (don't know if I should laugh or cry..)


Removed all the paint masking on the casing. Here you also see the heating gun desperately trying to heat up the casting


Disassembled the clapper box, to make it clap again




I also noticed that the tool slide nut seems like a repair job


The tool slide and clapper box are all numbered 20


While the main casting and almost all other parts are numbered 10. This makes me believe the tool slide has seen some serious damage, and has been changed. Makes sense, as this machine comes from a school.



Then my camera decided that it needed to be charged, so a couple of hours work missing here..

Aand about here it started to work again




Main saddle ready to be mounted




This is how I left it today, the following pictures are just gloating




One of my HSS tool holders from the lathe seemed like a good start for a shaper tool



The current assembly is just to get things together, in order to make a test of the machine. After all, I still don't know if it runs..
There are a few things that need to be sorted, amongst others, a few brass bearings that need replacement, the feed selector which isn't working and upper bearing on the "arm" which is shot.

I have also noticed that the paint has not dried properly in places where I sanded down to the filler material. Here the paint has just stayed gummy and is absorbing every little piece of dirt I manage to get on it

[Trion]

I got some more shop time this morning, and all of a sudden the machine looked like this


I filled up the gearbox with some hydraulic oil


And bodged up a 3phase connection. Suddenly things started moving
Still quite a few things that need to be improved, but it works. It doesn't make too many weird noises either!


Interresting to see in the transparent gearbox cover while stuff is running. It also shows how easily the gears start spinning when the clutch is not in absolutely "open" position


That's all folks. Now the tedious job of improving all the small bits and bobs begins

[slowcoach]

lovely job you've done to that shaper, it looks fantastic 

Rob

[cidrontmg]

That´s one nice shaper! It will be spitting chips all over the place anytime   
With temps that low in the shop, how do you keep steel/iron things from getting rusty? I had my shop without heating one winter, in Portugal, where it seldom goes down even to 0^o (although it´s 0^o outside right now...). In the spring, everything possible was rusty. Mostly just surface rust, but there are still rust pits in some of my tools. And some I had to throw away and replace. I had long sessions sanding, scratching, oiling and cleaning that rust away.
 

[Davo J]

Once you have it finished you will have a useful tool their. I have 2 and wouldn't part with either.
We never get down to 0 in my part of Australia either, but still get rust in the winter. I use a 20/80 motor oil kero mix sprayed onto all bare metal surfaces and tools before putting away. The kero thins it so it can be sprayed in a cheap spray bottle then evaporates leaving a thin film of oil behind.

Dave

[Trion]

Thanks for the kind words. I´m quite pleased with the result too

Regarding rust, I haven't had too many problems with that yet. My shop is an ex military storage with wall thicknesses that surely would survive a nuclear blast. This also makes temperature changes very slow. As long as the temps are going down, the parts inside my shop should be warmer than the outside air, not making condensation a problem. But of course, when outside temperatures and humidity rise, the machines may suffer from condensation. To prevent this, I keep all bare steel surfaces oiled with hydraulic oil at any time, well I try at least
But it looks like the winter is going to be a long one this year too, so in order to make my shop usable I will try to make a small room around my workbench and machines, and keep this at a steady temperature higher than 0. It is going to be a big part of the electrical bill, but it should be worth it!

[Rob.Wilson]

Looking great Trion 

Sure is a nice bit of kit to have around the shop 


Rob

[Artie]

It does look great mate, Ive had this discussion with a friend and we both agreed to leave the shaper and the HZ mill in their natural state, the shaper is almost 60 years old and the mill is just under 50 years old, preserve the 'patina' so to speak.....

but.... now after seeing this, im not so sure......... 

[Artie]

and cut some bloody metal already! And show us pics.....

[Trion]

Thanks Artie! Now you know how I felt, when searching through other peoples shaper rebuilds before I got mine

Before I can start cutting, I need/want to sort out the feed mechanism which is useless at the moment. There are also a few other things requiring my attention, but you´ll see when I get around to do something about it. The plan for today is shopping for christmas gifts, and maybe read for the next exam

[Trion]

I got a bit of shop time yesterday. Now with constant heating on in the shop, there was a comfy +5 degrees

First up was the sideways feedscrew, which looked to have been modified at some stage


The axial thrust is taken up directly by the dial (this is not entirely true, as the dial support is very rigid, while the dial can slide back and forth on it)


And on the other end, only a pair of "interlocking" nuts provide the support


So I found one of my precious brass bits and started turning


I call them thrust bearings




When assembling, I noticed that this brass washer brought the whole feed mechanism outwards and would bend the "feed shaft", so I had to remove it.


Here it is in place and tightened up


For rapid table feed on a manual shaper, a battery drill and an inverted hex bit prooved good results


I adjusted the table gibs, but while doing so I heard a small "ping" noise from two of the gib screws. They snapped right of, although I was only applying torque with the short end of a allen key



This screw holds the feed mechanism to the "feed adjusting plate", and frankly the cylindrical part is too short. When fully tightened it binds the feed mechanism to the plate, making it unable to rotate. This looked like a bit difficult machining for me, but I decided to give it a go


Roughed out the shape in some steel. No matter what I tried, I did not manage to get a nicer surface finish than this


Then there was time for the thread. You might think, that's easy, a Sweedish machine should have regular metric threads. But noooo, inches seemed to be the way of measuring back in the days. Knowing nothing about inch threads, my thread gauge figured it had a pitch of 11,5 per inch, so I had to change the gears on the feed.


After a few small blunders, my first actual single point thread came out. I figure why you all think a swinging threading tool might be handy


A bit later, and I parted the piece of. I even tested it on the threads, and it fit!


So next time, I'll have to mill a head on it

[DavidA]

Just think of all the things you can make with the machine.  To paraphrase H G Wells,  it's ' the shaper of things to come'.

Sorry about that.  Couldn't resist it.
