Re: My latest Project - Part Two

Great work Mark!

And thanks Joe! Sounds like quite a trip. The guys offered me very low, and were quite rude about it, so I passed and will keep looking

Re: My latest Project - Part Two

Wow!!!


Really really cool!!


I was wondering where the giant round plates were going to fit in.
What are the dimensions of them?
Looks like about 1- 1/2", I hope you have had that in stock for the last 10 - 15 years.
I'd have to pay about $100 each for those two pieces at today's rate.


Looks like a great setup.

Re: My latest Project - Part Two

Mikey, you've better opportunities that won't cause a compromise,
I think your values are higher than theirs.


A zillion more around the corner that are bigger, better.


No hurry.
It will find you.

Re: My latest Project - Part Two

Thanks guys;
The round plates are from a nearby scrapyard, I pay for the weight. He's getting a little more reasonable with me now, I pay a little less than I pay for new steel. 60 cents instead of 85 per kilo.
They're 20mm, 3/4".
The H beam is a small one, 100mm [4"] I was trying hard to maintain the head clearance, and have as much lift height as possible. And I wanted the arm to be able to protrude out the door, which is why I made it with an arm.
The pivot bearings are leftovers; top one is a used wheel bearing from my car.
The winch I got at auction 12 years ago for $20.

I tested it by lifting my massive drill press, which I guess weighs at least 350kg.
The flex in the arm was as expected, 10 or 20mm. Rotation on the arm is fine, but the wheels wouldn't roll; I couldn't push it forward or back with the load.
With the lever force, the load on the front wheels is about 3x the weight of the lift, and 2x the weight forcing the rear wheels upwards. I didn't think it would be a problem.
I'll probably add a light rope and pulley[s] to pull the cross beams forward and back when under load.
It moves easily by hand without load.
I should have used bigger channel for the wall tracks and bigger diameter wheels.

Mikey, low starting pay might be acceptable, but with rudeness attached? Definitely not!
A sure sign that they treat their people badly and won't ever pay or treat you right.

You could put a floor jack under it to assist.



Counter balance?


Your metal prices beat my 95 per pound for new.
Great pictures, looked twice as large.

This I just don't understand; we pay 23% tax!!!
Steel is a competitively produced commodity; even with tariffs [I don't know if that story is still ongoing], there's no way you should be paying double what I pay.

We had a few days of rain [Yay!]
So I asked the fire department if I can burn my wood pile tomorrow; they said I can.
It's got a couple of tons of pine logs in there. It will be a biggy.

The Mercedes has a leak at the top of the fuel tank, so I have the rear up and stands. It seems I have to take the rear end out, as well as the drive shaft + exhaust system.
If I'm going that far, I figure I should do the clutch too [it slips just a tiny bit when hot].
But for that I need another pair of jackstands; being a cheapo SOB, I didn't want to pay 60 Euros.
They're not getting 60 Euros out of me!
So I made them yesterday. Only 20 Euros worth of material and 4 hours work.
And they aren't painted yet.

Re: My latest Project - Part Two

Yeah, the tariff thing is still ongoing. And it also depends on the business environment as well, such as local regulations & taxes, wages, land costs. Lots of reasons why there can be significant price differences across the USA, let alone between different countries...

Re: My latest Project - Part Two

All those things could add up to 10%, maybe 20%.
I think the main difference is that I'm buying from a steel yard; they sell tons and tons every day.
They will only sell whole lengths [6 meters, 20'].
Most of their weight is rebar.
I used to buy a couple of tons at a time when I was working [biggest score was 8 tons]. Then I'd shop around for the best price each time.
FOr the 8 ton purchase, I specified a delivery vehicle with a crane; they sent t without one.
"Crane truck is broken" the guy said.
I told him to come back when it was fixed. The bigger plates weighed 1000 lbs each. The small ones 450.
No, you will not dump my cold rolled ship plates onto the ground!
That was maybe 1999 or 1998. I paid a Dutch guilder a kilo, around 20 US cents a pound.
Ah, those were the days.
Chinese and Russian steel dumping made money for me.

Re: My latest Project - Part Two

Nice hoist Mark.




So ironic, losing my job cause they are not making money, we have so many orders right now, we won't be able to fulfill them all when we officially shut the doors in June.





I maybe going against my best judgement since i do not like green and yellow,.....I was given a JD L110 hydro, going to use it to mow my lawn. We will see how long the Tuff Torq K40 tranny lasts on my steep hills

Many orders but not making profit?
Something's gone wrong there.

Anyway, such things are beyond our control; whatever you decide to do next, I hope it works out for you.

Re: My latest Project - Part Two

Not really, it's pretty common for a small business that is successful at one size, then expands and goes bust, not because it is no longer successful, but because of cash flow problems, or even management problems.

For example, say you expand into say, Walmart. You suddenly have to produce a whole lot more units to go on their shelves across the country (or worldwide), but you don't get paid for any product for months, and (this also makes getting loans more difficult) you have to take back any product they don't sell or is returned(including anything Walmart themselves damage).

I think it's more the fact our customers do not have backup pigments they can use in their ink formulas, they depended on us as their only supplier. Everyone is scrambling to build as much inventory as they can until they can search for other manufacturers, they are giving themselves a buffer.



We were told that our company has always been an "ink company", not a pigment company and also from my position I am in, I can see they are going to be buying their pigments from India or China, probably cheaper than we can make in the US. These new tariffs are killing us on our the foreign raw materials we use to make our products. It's cheaper to bring it a usable finished good than the combined tariffs on all the raws.

Re: My latest Project - Part Two

Hey guys, how is everyone doing?

So, here is my new project. An homemade indexing head to use with the milling machine.

I've had this worm drive box hanging around from an old big milling machine that was used to move the quill up and down, by either a hand or by a crank handle for fine feed.

All I needed to do to it was adding bearings on top and bottom of the worm wheel shaft. So here are some of the parts I've made, minus the worm drive.

I machined the top and bottom of the box so I can have reference surfaces to align everything. I also need to machine one of the sides as I plan to use this indexing head in either vertical or horizontal position.

Here is the chuck and chuck backplate. Both saved from the older lathe I used to have. This 8" chuck is massive for this project but we will see how it goes. Maybe I can get a cheap 5" one or something later on. I machined the threads on the backplate to match the ones I did on the indexer spindle.

So the plan with this, is using a stepper motor along with it's driver and a Arduino with the LCD 1602 Keypad Shield and a program to run this thing. This should allow me to get very accurate divisions. Therefore allowing me to make accurate gears and bolt hole patterns.

Here is a video showing what I'm trying to explain:

Re: My latest Project - Part Two

Awesome hoist Mark! Maybe a sliding counterweight would help with rolling the trolley.

Mikey, good for you. You'll find the right employer with the right offer. I agree with Mark and Don. If they are rude now, imagine how they will be when you are their employee. Run, don't walk!

Pedro, that indexer is great! I was never good enough to cut gears, but we had guys that were good enough. I loved to watch them set up, when I could. They only had a manual indexer to use. I should make a video to show you how I was taught to tin wires by a lady that used to make cable harnesses for Sikorsky helicopters. You hold the wire between the middle finger and ring finger and hold the solder between the thumb and index finger. The soldering iron is in the other hand. You bring the iron to the wire and advance the solder. Done right, you could push up to an inch of solder. The wires you were tinning wouldn't need even an eighth of an inch of solder.
