Jack, The top disc does have a guard!?
The lower one sure doesn't.

(I don't see rise and fall or table tilt on the line belt machines? Just like Wadkin to make small changes over time with big changes getting a new second letter.)

Both the bobbins appear to have tilt tables?
the adjustment would appear to be the near vertical rod with the locking handle.

stock wadkin only came with 3 size bobbins?so i rolled my own. Have a look here if your missing some sizes.

Here is a Catalog cut from a 1927 Wadkin catalog Jack, hey nice to see you posting this side of the pond too !
Not much unisaw stuff here I'm afraid...lol



Melbourne Matty.

Jack,

Thanks for you comments, and the link to your thread on bobbins and for dropping over this side of the pond to post. The J.U. was a reciprocating sander, and did cant 30 degrees below and 15 degrees above horizontal, it had a scale for registering the principal angles and plunger stop. It was either supplied with a fan like the ones in your picture, or hood and piping without the fan, like one of Matty's pictures (the JU is in my 1929 catalogue). The obvious changes were the motor drive and handwheel for tilt, but I always thought the other big change was the addition of a dust port in the table casting, so it was a big shock when I found this one was designed without the dust port. I am glad that Matty has confirmed the J.U. was the model before the JY, as the table is clearly not a JU table (the JU table top looks completely different to the JY, and everything matches in the casting, bolt holes etc with the new JY table), so obviously the JY was originally released with a dust collection attachment like the JU.

I think it's pretty cool if this is the 7th JY produced, it's interesting that you have also heard the same thing about the machines starting at 100, I don't suppose you remember where this theory originated, is it something that Phil discovered in his research??

So my one must be some time after 1929.

Cheers,

Camo

There is a post on the Canadian forum where one of the members has recently acquired a JY, and a similar story of searching for a long time before finding one. I have been looking at machine numbers and test numbers of machines to get an idea of how many JY's were made. This is what I have so far:

The machine just posted on the Canadian forum is machine number 569 and a 1954 machine, one of the guys in the UK (Mark) restored a 1965 machine and it was machine number 685, so 116 made in 11 years, another one listed for sale now, is a 1979 and machine number 876, so that's 307 in 25 years, if we assume machine numbers started at 100, that's 776 machines made by 1979, makes me wonder how many in total were made, then how many made it to Australia, and then ultimately how many survived until today.

There definitely out there, but I was thinking there would have been more made.

cheers,

Camo

The 100 thing was used by a number of makers and the seral numbers on machinery makers over at Vintage machinery wiki show many that used this starting point. I have yet to see a Wadkin number before 100 but not many tags have been listed yet. By you own number study its unlikely yours was 107 given how many were made over the years.

here is my tag for the study.


Not all maker used this and there is only speculation as to when the numbers start but there is proof that it is likely.

Now the question is does my Burrows and Green MZ start at 10 or 0

Jack,

I think your right about it being more likely to be machine number 7 than machine number 107 based on the information at hand at the moment. I will start keeping my eye out for sub 100 tags.

Thanks for the photo of the tag, just trying to make out the second number of the Serial number, is that JY 498??

Cheers,

Camo

P.S. I love that Burrows & Green bandsaw, had not picked up on how early an example it was until now

Cam, I'm back on but not sure if its all A OK yet so here is a sample pic from my stash.
H.

PS I have a bit on double discs etc , should I add them to this post or start a new one?

Cam,
This is from a 1936 cat. The previous one from the Aussie leaflet which is 1930, note the disc glue up clamp on that machine.
I will try to put up my earlier full cat stuff tonight, slight difference in machine but the stuff sanded and operators are the same as one of these.
Even without digital I guess they could mod the pics as they liked.

Henry,

Very interesting! So assuming the Bobbin side of the JT was the same as the individual Bobbin sander, then that means I can now narrow the build date for my machine to within 1930 (after the catalogue was released) and 1936 (before the catalogue was released).

Interesting concept with the built in glue clamps, how messy was the original glue process? Perhaps this is why they changed to an independent clamping stand?

As for posting the stuff on the double disc machine, I don't mind you posting it in this thread, if you would prefer not to start a new thread, it's up to you, but I would certainly love to see them.

One thing these pictures have taught me about pattern makers though, they were very messy, just throwing there patterns all over the floor.

cheers,
