Hyco Lathe

[Leef]

Hi Guys, Hoping for help.
I am the Treasurer of the Dumbleyung & District Men's Shed and we have purchased some gear from the local Ag College.
One is an old Hyco Wood Lathe and I am trying to determine the spindle size, because we want to purchase some new faceplates. I am getting a number of differing answers, and it is confusing the hell out of me. I thought it was 1inch by 8 tpi, someone else said 3/4 BSW and now the guy from the engineering works thinks it is 22mm 2.5mm, although the lathe seems to be way before metric.

It is 3 phase.

Can you help.

PS I haven't found any model no's, merely the embossing on the headstock cover.

I don't know the exact answer, but havng experienced this problem with old lathes at my men's Shed, I will bet it is 3/4 BSP. Take along a garden hose fitting and see if it screws on.

You can thank me later - or not...

Thanks for the reply. I'll try that.

Get set to be confused more.:D Most lathe of that era were 1"x 8tpi. This was the standard on most Australian lathes until the mid 70's when it changed to 1"x 10tpi

Does it look like this one?

If so it's a 1" x 10tpi spindle.

I looks similar to that photo. I'll have to go to the shed and confirm a couple of details. Thanks guys

Did what I should have done, before I got flustered on the advice. Both ends of the spindle appear the same size.
The outer has 10 threads/ inch; the inner about 8 in 3/4. So I'll go with 1 inch 10tpi

Thanks for all your help

My Hyco is also 1" X 10tpi

But, you never know if yours has been modified.

my Hyco is 1 inch 10 BSF it has the oil pots on the bearings, if getting teknatool chucks you will need a C insert! my lathe was dated around 1950s. not sure how spot on that date is tho!? can't remember what brand the faceplate is I bought at wood show but they had inserts to fit!

Thanks guys for all the help. Next step will be to decide what size to adapt to -
Common sizes over here appear to be 1 1/4 8tpi or M30 3.5 for faceplates. Nova chucks have an insert for theirs.

Those two sizes are common for larger swing lathes. My Hegner 350mm swing uses M33 X 3.5, and my 1995 Woodfast 20 inch swing is 1 1/4 X 8. Most common for "normal" size lathes in the US is 1 inch X 8 tpi.

The M30 3.5 seems to be fairly standard in AU.

If you have several lathes and want to use chucks and face plates in common, adapt to the largest one. Keep in mind the larger thread face plates will be more expensive.

Also the more connections and the further you are from the spindle nose, the more likely you are to have wobble of face plate or chuck.

This can be gotten around bu carefully marking the piece if removed and putting back in the same position, or once chucked or mounted on the face plate, completely finishing the piece.

I just bought this exact model for $100, just in the process of getting it up and running. Your input here has helped me so much, thank you.

Hi

I have the same HYCO lathe as the pic. I have stuffed it somehow and the pulley is turning on the shaft - do you happen to know how to remove the shaft? It would have to be done to change belts so it can't be too difficult - I just thought you might have experienced something like it and can tell me if there is a simple method or do I need a real big hammer!!!!! I need to put in some grub screws or something similar and taking the whole shebang up to the local engineer is a bit drastic I think.

ciao
