Thread: Yeh I have my chuck VICMARC VM 100

Ian have a look at this a its whats called a Legacy Lathe but with indexing on a normal lathe there are ways to do much the same things.

NOVA CHUCKS: AN OVERVIEW

But still no indexing fixtures so why do all these different brands go to the trouble of drilling the holes and have no accessories for them

The vermec option is great as I have used mine a few times

I made one myself, not too hard to do.

I'll go one better, my indexing is built in to the headstock spindle

I like my Nova 3000 for it Fred haven't used it but will be soon.

Jim I am sure I said similar in another thread when rssr mentioned indexing on his chuck I asked to see to see his set up didn't have one i think.

Sturdee yes simple to make a index pin set up, still yet to do one for the Jet Mini I have the plate and the tongue just need to mount it.

Y'know, the forum still has a Search feature. Here's a simple, but effective, device for engaging the rim holes: https://www.woodworkforums.com/f8/index-jig-mc900-87645/

And speaking of cupcakes, I just eyeballed the index positions for scratching the flutes for a new batch of cupcake earrings. ( https://www.woodworkforums.com/f8/cup...rrings-113147/ ). Test marketing this coming Saturday.

Cheers,
Joe

Hi Wheelinround

that lathe looks very awsome but also so very high tech i think it will be a while before i do anything like that im just happy learning all that i can from you guys many thanks for the info

Cheers Nai

Hi Nai and others

attached is a pic of the indexing jig I made for my MC900 - it clamped down to the bed and had a pointed screw that wound up into the indexing holes around the outside of the Vicmark chuck.

it was made out of plywood - easy and effective, but a bit fiddly.

cheers,

Colin

Hi Colin

That jig looks very simple and easy to use compared to some i have seen. Now for the stupid questions again how do i use it and what are the benifents of this

Cheers Ian

Hi Ian

The jig is really only about being able to hold the chuck still in a known position while you do whatever to the workpiece.

The Vicmark chuck has 24 numbered indexing holes equally spaced around the outside edge, and another 24 on the back face. That means each hole is 15 degrees away from each of its neighbours, so as you rotate the chuck (and the workpiece) hole by hole you are stepping around the piece in 15 degree increments.

My jig clamped onto the bed right under the chuck, and I screwed the pointer up into one of the perimeter holes (say no. 1) and locked it with the wingnut. Then you do whatever you want to do to your workpiece at that point - maybe rout a flute along the outside, or drill a hole, or carve a feature, or just make a pencil mark along the top of the tool rest to locate something. Then undo the pointer screw, turn the chuck the number of holes (ie the number of 15 degree steps) you need to suit your pattern, lock it up and make your next feature. Keep going until finished.

Other systems use a springy or spring-loaded bar attached to the headstock to engage the holes and hold the chuck in place - the result is the same. The beauty of my jig was that I made it from scraps, plus a couple of hardware bolts and T nuts and it didn't involve drilling holes in the lathe. However it was bit slower to use than a springy bar would be.

One of the things I made with it was a raised cake stand in Jacaranda, with 8 (I think) pieces of 25mm diameter cedar set into it (at 45 degree spacings). From memory I think I used the jig to accurately mark out the hole centres which I then drilled with a 25mm forstner bit on the drill press.

One of the challenges is to make sure you keep count of how many holes you turn the piece each time - one step of one hole too many will mean you finish up one hole past where you started - tends to mess up the pattern.

This post ended up longer than I thought - sorry if I have been a bit long-winded, but I hope it helps.

cheers,
Colin

PS - I gave the jig to Ozkaban (Dave) when I moved from the MC900 to a Nova 3000 - he now has a Vicmark lathe so he might be pursuaded to pass it on if he still has it.

Hey Colin

Thanks heaps that makes me un derstand it a bit better and will do well in the future when i use it and its ok to be detailed sometime thats what people need i think i might make one and play around a little bit

Cheers Nai
