Mudski GU Build Thread

I just had a look at my drill press circa 1995 or so. Mine disent even have nuts mate. Mine has 3 pulley stacks for gearing. The main one on top of the chuck looks like it might have a keyway but the other 2 look like they are on a taper. The main Chuck is likely just a Taper up into the drill head too. They fall out occasionally. Pain in the ass when they do. Give it a tap to get the taper to bite.

Go in and flip the lid on one of the floor stock drill presses on display. Evolution has not really arrived yet mate. They will likely be the same.

I actually did that yesterday at the Total Tool near work. All the nuts on those were smaller, this one has a 25mm thread. Anyhow, I don't have the luxury of time, getting a mere 10 minute lunch break at work is unheard of. So I just welded the pulley on. I've never even lifted the lid on mine in the 10-15 years I've had it, so I doubt it will never be lifted again.

Anyhow. I’ve plug welded the first half. Came up ok for a novice welder. I had my little 135amp welder running at its highest level with max wire speed and things got pretty hot. But it worked out in the end.

I won’t be doing anymore until next week now as the wife and I are heading down to Wilson’s Prom for the weekend. I need to recharge the batteries by doing sweet FA for a weekend and I can’t do this at home.

Looking good mate. And welding will work just as well as a left hand thread. Lol. Does your drill press bot have stage pulley on top to change drill speed ratios?

[Mickhead]

Your front pulley looks like a taper with a left hand thread nut. Clean both tapers and give it a tap when it's back on and tighten the nut. Do you have the nut? If not it should be relatively easy to find one at a specialist bolt or tool store.

It would need to be a farking incredibly good bolt store to pull a nut like that off the shelf…no chance at all .. or get an old school fitter who can use a lathe to make one. Or green loctite the pulley.😂😂

Yeah I does mate.

So I get home from my weekend off and I get stuck into it.IMG_5368.jpg

It’s not perfect, I’m a bit heavy handed on the flappy disc so there’s a few imperfections but it’s come up pretty good and is strong as hell…

Nah not at all mate. Left Hand thread is a pretty common concept. You won't find them in a 25pc unipac but you'd have no trouble finding one.

Not even trying



It is probably an imperial from that era. But readily available.



I had my own Cabinet Making business with 20 blokes in the 1990s and would not even miss a step finding that nut to be honest.

Mark, looks original to the untrained eye

Thanks to you John. A bit more work than running the angle on the outside but it has come up a lot better.

Mate.. I have shitloads of Left hand taps and dies, all in common metric format like M8 x1.25 etc… looking at the nut on the drill press its gotta be at least an inch in diameter with 14 to 16 tpi left hand thread. Find that at the bolt bloke or aliexpress and impress the audience….������

So I managed to get the jerry swing away on today. Bitta mucking around, drilling and tapping holes. Last hole I was on, I was running a 6mm tap through it and I put a little too much sideways pressure on it and snapped the fucker off in the hole. Ugh! No chance of drilling it out so out came a centre punch and heavy mallet and I punched the broken piece out.

I also put a hole on the carrier so the tap for the water jerry can sit through.
