Toolmac Woodlathe

[woodhenge]

G'day all,

I am new to these forums and because of viral encephalitis have forgotten most of what I know about working with timber. I have decided to try to get back into it as I used to really love it, but I keep finding I have forgotten things. I have acquired a Toolmac woodlathe Model 87-531592 to replace my former gear - a Durden(long story involving divorce). What I can't work out is, what thread is on the drive spline thingy. I think it is 1" x 1:8 or 1" x 1:10. Does anyone have a manual for this type of Lathe?

Regards

Neville

Hey Neville,

couldn't find anything on the net about your particular model of lathe. However just picking up an old second hand lathe myself, I've just been through the same process of identifying the spindle size. This thread here is pretty helpful, but more so the link Skew provided here. Check it out and use some calipers to measure your spindle and find the appropriate spindle size.

hope it helps

Cheers,

Will

wish i could help but i know nothing of that lathe.
but you could either count the threads or press a lump of blue tack or plastasine onto the thread or take a rubbing with a piece of paper and take it to some where that can tell you what it is

Well best guess from measurement is 1:10 x1" However it could be metric as it is closer to 25mm than 25.4 and the distance between threads is around 2.5 giving pretty close to 10 per inch.

I notice the inside of the spindle is set up for morse taper, has anyone got any idea what morse taper would be likely to fit this spindle?

Regards

Neville

most probably a number 2

Most likely will be Imperial going on your last post, so it'll be 1" x 10 TPI as there isn't any Metric threads at 25mm on the wood lathes usually

Morse Taper Shank Sizes

All common woodworker's lathes and drill presses use a tapered spindle for mounting your tooling. They are designed for a male ended, slightly tapered shank that fits into the machine's hollow housing. The action of the tooling forces the collet farther into the housing, increasing the surface pressure between the two metal plates and the resulting friction prevents slippage. The design provides accurate centering and quick installaton of drill chuck arbors and lathe centers.
In order to simplify the fitting of these two pieces a number of standards were developed and adopted in the industry, the most well know being the "Morse Taper" (MT) developed in the late 1800's.
There are 8 sizes ranging from MT-0 to MT-7, each with a given size as outlined in the table below:

These folks sell Toolmac things, no lathe listed, but they might know something.

Hi Guys and thank you for your help and guidance. The solution has been found! The ToolMac Lathe is the precursor to the Toolex 900mm lathe. The main thing that has changed is that they have changed the thread from 1" x 10:1 to 1"x 8:1 in the toolex. The Toolmac is 10:1 imperial thread with a No 2 Morse taper, 6 speed, geared head which will rotate 90 Deg.

Thanks for all of your help
