Fixing a BEEPload of backlash

I like how methodical your approach is to every endeavor you take and that you make due with what you have on hand

That's amazing. I tolerate (pun intended) more and more back lash. You can deal with it to a certain point but gotta be fixed eventually. Thanks for the video!

Congratulations, Michel!!! I am from Brazil, have some Proxxon machines (Lathe, Milling) and enjoy your videos. Basically I face the same problems with my Proxxon here. Your contribution is inpiring!! Thank you.

elegant solution to the problem ! Ill keep it in mind when I get around to doing my mill, best regards, Steve

G'day Michel, bloody marvellous!

It is interesting that proxon had not used an adjustable bronze split nut to compensate for backlash as it wears. Nice video as always

The grey cells are coming up with some clever ways to get things done, good job!

Really nice tight tolerances now, what a great upgrade. Cheers 👍💪✌

Great workmanship once again.

Terrific upgrade Michel, Well done!!

Very impressive! I have the same machines, but couldn’t do that sort of accurate work on them.

Bloody nice job on that sir! I like it a lot. I'm going to revisit my X axis nut on my 25 year old Warco WMT300 lathe/mill combination machine. It has a very weird trapezoidal 20 mm X 0.1" ( 10 tpi) thread. I made a new nut in brass (which was my big mistake ) but due to a chipped tooth on a change wheel, I mucked the first one up and left it for a few months to ponder how I could do the job without ruining a second one. I decided to make a tap first and used a piece of steel from a Range Rover anti roll bar as this is good steel, a bit hard to machine but I managed it. The second nut was brass as well, (big mistake) and I managed to make a usable nut with only about ten thou of backlash. I also cut my leadscrew to swap it end for end using the unworn tailstock portion to even out the wear in it I made joining sections at either end to put the leadscew back together in its proper orientation with the machined bearing and driving potions back in their proper places.mi also cut 30 mm off of the very end of the unworn part of the thread as a go gauge and the tailstock joining piece was made 30 mm longer to restore the length of the screw. This has worked ok but after two years of hard work I have a lot of golden sheen glitter on the leadscrew and around 25-30 thou of play again. I'm not sure if I have enough room to do the half nut idea as you have, but I'm going to see what I can do to replicate your idea, this time in bronze if I can find it. We have now no engineering suppliers locally as all the engineering firms seem to have disappeared here on the London/Essex border. We used to have a brilliant engineering supplier about three miles from me but they closed their doors more than ten years ago now. A great pity that as they had been in business since before the Second World War. I'm going to watch this carefully again making notes and screenshots to replicate your half nut idea, if you don't mind. Sorry to be long winded lol

Excellent video. No need to further investigate, brass has the tendency to transfer to the mating surface, bronze does not.

I'm new to your channel--that was great! Real nice work.

The master at work, nice video, thanks

Ever a pleasure, Michel!

Very nice work sir

might be an idea to dril in an oilhole from the t nut slot in the tables surface down intoo the capture nut for the leadscrew to be able to drop a little oil in there once in a while using a siringe and a needle

It seems quite evident to me that from your hardness tester results, there can be no mistaking that proxxon used two different materials. Not something you'd expect for the price they want for it now! I have their miniature table saw and the die grinder.

Nice video 👍😀 Was that 0,7 mm backlash ?... that will ruin a part if you are not careful 😢. A bronze split nut is a good way to solve a problem like . Offcoarse there are different solutions or materials you can use. But bronze is self lubricating. Specially if you use bearing bronze .
