The steady doesn't have to be accurate but does need rigidity. Don't be 'greedy: and make it too big   .  If you need to support the centre of a long bar,  consider how you get it on and off .

Project Logs / Steady for Harrison
« Last post by shipto on March 14, 2024, 03:01:48 PM »
I find myself in need of a steady for my lathe and looking around was 1) not able to find anything suitable 2)  :bugeye: shocked at the prices. So whats a Madmodder to do?
I am making one, I started by making something to sit on the bed from some channel (pic1) this bit is complete. did not have phone in shed so actual pictures will come later.
Next bit is the make the guide ring? and so far I have bored out the holes for the guides themselves.
Will post more as I go along.

The knurls never bit down hard enough, what is your material and has it work hardened ?

Another point, were the knurls clean of swarf, metal particles.

I ran slow with tool on centre and added pressure by tightening adjuster with oil.

I don't think it matters which way around the knurls are.

I start with the knurl quite loose to establish a bit of a pattern and then tighten the clamp up to make the pattern deeper.  The clamp has to be properly on top and bottom of the work otherwise it'll be pushed away from the work.  Oil helps.  Some people say you have to get the diameter right so there's an exact number of knurl patterns.  I haven't found that to be the case.

Tools / Knurling
« Last post by Dell on March 12, 2024, 11:50:03 AM »
I made a couple of knurled knobs but when knurling them I couldn’t get a very nice knurl , I couldn’t get knurling very deep and it was better on both outer edges but the middle of the knurl was rubbish , I have a scissors type tool in the rear tool post on my Myford 10, the shorter one I am very happy with and was done some time ago from the front but the longer one I made today using same tool but from the rear, I thought maybe the knurles were the wrong way round so turned then over but I didn’t try moving bottom one up top and top on bottom could that be the problem?

Hello Folks,
I am back on the Holbrook and feeling much better, thanks to all the well wishers, really appreciate your concern!
Week two (or rather three days) of work on the Holbrook lathe some bits arrive, and we find signs of tailstock abuse, but as usual it is press on and fix them all!
Phil, in bitterly cold East Yorkshire,
Tell Greta I want a refund!!

Heat and especially direct sun kills anything and everything.

Sails on sailboats last about 2 years, charter, here in Spain.
And 10Y+ -- forever in the UK, partly due to being covered and or not in use part of the time.

Air-con units in Roatan, Honduras, last about 6 months, due to the heat and sunshine.
According to the guy who knows, and operates, lots of them, when I was there ..
