A very quick and cheap little project. My lathe does not have an indexing system, because it is a really cheap and nasty lathe. This little projects has two main components; 1. a piece of MDF and 2. a horizontal toggle clamp.

start with a square of MDF, find the centre and mark it (DO NOT DRILL IT OUT YET), next mark out the index holes you want, this one has 32 (11.25° increments), 1, 2, 4, 8 & 16 increments are also possible with equal spacings . Drill out the index holes ( the size depends upon the tip of the rubber pad), then drill out the centre hole, I used a forstner bit close (slightly smaller) than the diameter of the spindle thread.

I then threaded on the MDF to the spindle (the steel thread cuts into the MDF really easily) – I then screwed on the chuck to lock the MDF into place. I then turned the square plate into a perfect circle and softened the edges.

Next come the fitting of the toggle clamp, this must be positioned so then when it is engaged, the soft rubber tip engages the holes centrally – A little shimming with a Ply wood block fixed to the housing of the pulley assembly.

That is it – I have used the lathe with the indexing wheel attached, whilst turning at high speeds without any problems. When using the indexing wheel, I always remove the power from the motor, to avoid any accidents.

You can make any number of wheels with the required increments for your project – I hope you like it.

Update: About a year ago I said I would post the project I made with this jig, well better late than never I suppose, also find attached e few photographs here of the legs.

Took me some searching to realize what one would do with an indexing wheel. After a bit of looking the light bulb has come on. Fabulous idea, I like it!

What sort of projects are you making with this jig? I like MDF, I used Lexan polycarbonate for an indexing wheel against a stationary Lexan reference point on a recent project, but MDF would have been a good choice too. I’ve never tried threading MDF, that’s an interesting idea! Good work!

Nice solution. Well done. I recommend numbering or referencing degrees at each hole. I brain lapse on stuff that I haven’t dummy proofed. I would find myself missing by one hole from not paying attention.

Nicely done.
What do you use the indexing wheel for?
I have looked at some Jet Mini Lathe’s that have indexing avaliablity but no clue what they are used for.

An index wheel fixes the lathe headstock in one position, it also enables you to rotate the headstock (by hand) a fixed number of degrees (defined by the holes in the wheel) and again hold the headstock in that position whilst you work on an object mounted in a chuck or held between centres.

An example of this would be carving or routing the flutes on a Sheraton leg, I’ll post a project tomorrow.

Tony,
This is great, very ingenious and seems easy to make.
I’m keeping this one…

Thanks Tony, Just what I need. My lathe does have indexing but 24 pin.
I have a project that will only take a max of 16 holes, so your idea suits well.

Tony:

You didn’t say what you used to make the index mark. What we have used in the toy workshop for a drilling jig. We use a saw blade and use the tips of the blades to give the points. A 40 tooth blade would give 8, 16, 24, 32 and 40 along with 2’s 4’s, 5’s 10’s etc. a 60 tool blade has additional possibilities.

Just good old fashioned trigonometry, compass, pencil, ruler, bradall/punch and a sharp drill. lets face it – does not have that accurate.
