Just get some second hand ones.
They’re an interesting material and with a tough job to do where failure can be bad, it’s not worth bodging/guessing.
If you’re fabricating the setup pretty much any fork configuration will work for you so you’ve plenty to choose from.
Err not so fast.
Is this the hydraulic pump - in which case don’t get it wrong and send pressurised oil the wrong way, or suck air and run it dry and destroy it.
If it’s purely the direction of which way the wheel turns that shouldn’t matter, in the sense that it shouldn’t do any harm to...
It’s dead simple.
As weld metal cools it contracts which we see whenever we’re trying to weld something square and it pulls towards the weld as it cools.
Do that inside a circular object and that contraction is enough to shrink it considerably.
As an extra, the heat would be enough to undo...
I’d rather avoid lifting weights for a backplate - would you want to be stood next to a spinning chuck held on by the cheapest, poorest quality material available that only had to be strong enough to hold itself together for a weight block?
Cast iron is supposed to be better - both for the...
Weld a slide hammer on
Or
Pick the race apart so you can extract the inner race then all you have to do is run a bead of weld round the outer race and it’ll want to fall out on its own.
That’s without needing any fancy tools.
Being a welding forum, I don’t think a welder counts as a fancy...
I do plenty of fabrication with 2.5 and sometimes 3mm box, 1mm wire all the time. Can weld thinner.
If that was all I was doing I’d maybe drop to 0.8 but don’t see any actual need, and in my case I could be welding 10 or 20mm the next day so like an all rounder.
Old Cebora, quality machine...
Using a vfd is good because it gets you variable speed control.
I can choose whatever speed I want when threading and reverse at the flick of a switch, speed up on long threads etc.
I think they’re also a bit smoother running as well, less clutch rattle.
Builders are just as bad!
Expect the swivel bushes to be worn out on all four corners, pins/bushes worn everywhere. Brakes will be seized (don’t really use them so being external callipers they stick).
Oil leaks are to be expected, on the whole it’s not usually too bad fixing most things but...
Snap on do well. There’s a funny shaped one (not the hook, right angle or straight one) which you’ll probably use 90% of the time and this can be broken but they’re pretty good. New blades are a quid or two I think so not eye watering, though my guy doesn’t tend to charge good customers.
Just remember that they pretty much want to fall over and that there’s a lot of weight at the headstock end.
3/4 ton isn’t massive but it’s quite enough to go very wrong and you don’t want to wreck your lathe.
Take time to think, assess and double check everything and move slowly. Don’t let...
Can be done but for 9m+ reach you're at the limit of your budget and it'll be in a bit of a state - running, but only just, if you know what I mean.
6/7m machines can be had and fixed for within the 10k budget if you take your time finding one.
Don't rate Manitou at all, poorly built.
Merlo...
I've seen enough engine compressors set up like that to think it must be fine...
At the end of the day, the pump should be designed/built to provide air at its rated pressure, what difference does it make if it's blown out through a valve or being taken by a windy gun, spray gun etc as in normal...
You could just keep it nice and basic and have it blow off a safety valve when it gets too pressure. Valve dumps air, when the pressure drops again valve shuts. About £2/3 on eBay from memory, or rob an old compressor.
