That has to be nne of the nicest knurlers I have seen.

[Dave J]

I agree BobL,

Bob can you tell me the story behind the 2 piece handle arrangement?

Thank you Boys.

The castellated adjuster came about due to a desire to have a handle that could acheive considerable leverage along with being positionable away from the work or chuck. I could have used a spanner with the same result but the adjustable nut seemed a bit neater.

The tool works well on 4140 but I have to really wrench on the handle to get a nice deep cut. Some people use knurled handwheels on their adjusters. I think they would be struggling with something tough like 4140.

In reality I think most of the tool is 1020. If I had used leaded steel the thing would be covered in a rusty haze by now.

Bob.

Thanks Bob,
I did do a search through your posts but came up with nothing either I did find many other things to keep me occupied though. The toolbox made by the piano maker is fantastic!
LiveLeak.com - Best tool chest ever! for those who missed it.

I was thinking about making a few drop handles for Freddies's table support, but ones like you have made would be better, but i will probably add a spring as gravity doesn't work so well sideways......

Now you know why I bought a woodie's lathe.

Thanks Bob, I thought thats what it was for, but wasn't 100% sure as sometimes you slip in a little trick or two, LOL

Mine works easy as I have the thread on the end with the knurls in the centre, more leverage that way.
Also what size will it do, the one I just made will do 0 to around 55mm.
I looked all over the net last week looking for something simple, but most rely off the pivot points which could get sloppy. I went with a block type design something along the lines of what you have done, which stops any side way movement..

I forgot to add, you really did a nice job on that, mine doesn't look as pretty as it was a rush job just to do these adjusters. I see you have a Dickson style tool post as well, I have just finished 46 holders and am waiting for the grub screws as they are much cheaper than buying 184 square headed bolts.
The metric 8 where $177+ post per 100.

For $110 AU I got 1500 grade 14.9 grub screws from the UK posted as they where $50 a box of 100 here.

Hi Bob,
Hey, while you have it in pieces, re drill the Indexing holes in the Cast Iron Pulley.
The Spring Holder on the outside, has a Small Pin. I replaced mine, with a 1/4in. Pin.
I am now able to lock the head, to tighten up my Nova Chuck, with a piece of wood in it. Works a dream. I realise, you are not supposed to do that, but mine has never let me down yet, & that was done years ago.
Most likely try to tell you how to suck eggs, but the 2 x 3in Red Plates of course hold the Bearings. Mine have a Plastic Cap, that is removable, & I use Molycote to grease them.
Hoping this helps a little.

A knurling tool Log. Here it is ready for play.

Thanks for the pic and the others you posted. It's a nice robust knurler and the arms are located very well.

My purchased, relatively cheap, scissor knurler that I use ocassionally on my 9x20 has fairly loose arms that push over to the side when traversing along the job.. On the bigger lathes of course I use conventional knurls, but a nice robust scissor knurl like yours would be real good on the bigger lathes when one has to knurl a slender job.

I've stored the pics of yours in my vault of worthwhile and interesting do-dads, gismos, thingamabobs, dooverlackies and nice shiny things.

Cheers.

Hello Issatree,

The indexing plunger on my Tough has had the point ground off. I imagine this was done to prevent accidental engagement by some disinterested schoolkid. There were two other Toughs at the place where I bought mine, both had their indexers removed.

I will have to make an entire new assembly because I reckon the point and the knurled handle have been pressed together. I did think the indexing holes in the pulley seemed a bit small. How were you meant to lock the spindle for chuck removal if didn't use the indexer?

The bearings in mine seem to be in good nick. They have plastic shields. I'll pop one off and have a look inside.

Bob.

How did you find it Stu?

I searched for Knurl, Knurler, Scissor... then started wading through 57 pages of my posts before I chucked it in. Would have saved me a lot of rooting around resizing photos last night. As it was, it was past my bedtime whenended up posting a reply.

You posting that just shows how much I have forgotten.

I have 6 and am sick of having to change them over all the time. I had a piece of 32mm plate here for years that I was going to make them from, and after cutting them up thats how many I got out of it.
I made 10 blanks for those one off jobs etc, but about 4 of those are destined to boring bar holders, 1 a dial indicator, and one a threading tool holder.

I remember you knurler now (I even commented on it, LOL) but had forgotten about it.
