More Progress on the Mitre Gauge
First off, a couple of photos that might suggest why I'm going to the trouble.

I imagine at some stage the gauge has been jammed in the table slot and belted out mutilating the ring-in handle and pivot pin. The end of the guide bar was mushroomed and the pivot hole in both the cast iron gauge and the bar were badly worn out of round. If 3/8" x 3/4" bright bar was available I would have replaced the bar. Unfortunately it's not. I was disappointed to find that Woodfast didn't bother to centre the holes in the bar.

I used 'Rust-Off" ( a BobL recommendation and avaiable from Bunnings ) which contains 62.5% phosphoric acid, to remove the rust from the bar after wire brushing. It leaves a protective phosphate finish which hopefully will keep the rust at bay. The replacement pin is 4140 and is pressed into the bar and is a good sliding fit in the cast iron. The end of the bar has been radiused to remove the damage.

Spruced Up.
I had some spraying enamel colour matched by Global Coatings in Bentley and airbrushed it on. Not certain about the handle. The die-cast handle is from the Universal's lathe's tailstock and the thread is too short for it to become an interchangeable donor. The Kipp lever works well but seems a bit alien and the German made Lanker handle looks like a foreigner.
There is a possible alternative, cold cast aluminium, a process I know just a bit more than nothing about. Might be well worth pursuing.....

Have a look at the range of knobs that Festool use on their equipment. On some of them the bolt is replaceable so you can easily match your thread and length requirement.
They are all available as a spare part from any Festool dealer or from Festool themselves.

And now there is more.....
A young fellow drove up from Cowaramup this morning and we swapped bandsaws. We both came out in front.

Did he have any other bits and pieces for your machine?

No Bob,
It was an orphan purchased on Gumtree. I think the only bits missing from the Universal are the pair of 1 1/2" x 4 foot tubes. Oh, and the jigsaw.

Mounting the Saw
The saw sits on a spigoted cast iron base. Fortunately the base and the drive pulley were among the accessories Bob gave me with the machine. Strangely the spigots would not slide home in the corresponding sockets in the machine. They would go probably half way then bind. The machining of the spigots was poor. Rough as guts would be a more accurate description.
IMG_20201116_094810794.jpg IMG_20201116_094729573.jpg IMG_20201116_094746748.jpg
To achieve a good fit took me about four hours of filing, buing and test fitting. I was tempted to cut the spigots off and bolt on more accurate fitting replacements.
This leads me to wonder whether the original saw Bob sold to Bueller was ever actually used. Bueller said there were scratches inside the wheel guard but these could easily be made if someone turned the wheels by hand. The printed instructions were also still taped to the inside of the wheel guard....
With the baseplate installed it quickly became apparent that the drive and driven pulleys would not align. Woodfast mounted the driven pulley with the hub facing outwards on the stand alone Junior but for use on the Universal the pulley required reverse mounting. Bueller's photos of the saw's drive shaft showed an additional flat to facilitate the reverse mounting. It was a simple job to mill a flat.

Another strange thing I encountered when reinstalling the drive shaft was a 1.5mm gap between the bearing inner race and the inner circlip. Woodfast used two pairs of circlips, one pair to retain the bearings and the others to position the pulley and the wheel. I turned up a spacer to remove the possibility of endplay occuring.

Using a linked belt I was able to determine that an A21 belt was required.

The saw cut through a piece of sheoak that I have had sitting around for 35 years, like it was balsa.
Bob.

Extended.
When Dave and I swapped saws last weekend I mentioned that I was having little success locating 1 1/2" diameter steel tube to replace the missing 4 foot long tubes that would have originally accompanied the Universal. The tubes enable the machine to function as a wood lathe as well as providing outboard support for sawing panels.
I had found some 3mm thick walled tube in Melbourne which may well have been perfect but getting it here was going to be a problem. Then Dave sent me a message yesterday informing me that a local motorsport firm, Go Gear Racing Services in Mount Hawthorn, stocked 38.1 x 2.6WT mild steel tube. I had looked at their website previously because I knew they sold 4340 chrome moly tube but it took Dave's sharper eyes to find the mild steel.
Fitted, there are a couple of issues. I'm not a woodturner, last time I turned any wood was at WAIT in 1981, and from memory the cutting tool would normally be used at centre height. The tool rest sits too high in my uneducated opinion. Also the tailstock will require the addition of a spacing sleeve to provide some chance of ensuring alignment.
Mike posted images of the Universal's sales brochure in his refurbishment thread but unfortunately there is insufficient definition when enlarged to make out what Woodfast intended when setting up the lathe. It Followed Me Home, Can I Keep It? - Woodfast Universal Woodworker
Any suggestions regarding setup would be welcome.

Can you swap the sliding tailstock base with the banjo base?

Bob,
All 4 two way clamps are identical. The banjo can be inverted but then it collides with the rail if you were trying to work in close. Mike's brochure might hold a clue.
Bob.

Flip the clamp holding the banjo then you can lower the banjo.

Sorry for taking so long to get back to you Bob, been tied up with family & friends visiting.
I had a look at the brochure with a magnifying lamp, but it's still not real clear. It looks like the saddle for the tool rest is mounted up the other way & the tube for the tool rest is quite long, to enable it to come up high enough.
I does clearly show that the tailstock is just clamped in the correct vertical position, so your idea of a sleeve would ensure it stays in the correct place.

No worries Mike.
I was going to take some photos of the toolrest then I sidetracked myself...

There is a plan hatching here...

Wood Lathe Toolrest
Mike,
The only way clearance can be achieved is with the 3 way clamp and the banjo inverted. Seems too weird to think that is what Woodfast intended.
