In preparing for RRB-BO#14 I have been modifying some of my tools...
First off was my drill press, I got it for free, but it was a little gutless, it would stall out trying to drill a 1/4" (6mm) hole...
The stock motor was 360 watts and I had a large hand drill that was not doing anything rated to 1100 watts, it has a magnesium body with full roller bearings to handle big side loads too, so the answer seemed pretty simple to me...
Remove the pulley from the motor and TIG weld it to some 1/2" round stock:
Weld up a solid little mount to convert the motor mount to hold the drill solidly by the accessory handle and then clamp the body:
Weld it to the motor mount on the drill press:
Only thing left to do is wire it to the original switch, but I have tested it and it will drill a 1" hole through 1/2" plate with no issues!
The other tool that has been giving me issues was my little lathe, it is a great little thing, but you have to take tiny little cuts at a time because it will easily stall out. It had a 110 watt motor, I now had a spare 360 watt motor, I think you can see where this is going...
The old motor had a 11/32" (8.7mm) shaft, the new one had one a bit over 1/2" (a really weird size, something like 67/128" or 13.3mm) I didn't want to take all the material out of either the pulley boss or the motor shaft so I split the difference.
Drilled the pulley on my now over powered drill press to 29/64" (11.5mm) and then ground, sanded and filed the motor shaft with it spinning to the same size, the result was better than I could have hoped, perfect fit and runs dead straight and true!
TIG welded up a sandwich plate to sit between the lathe bed and the base plate and extend out to mount the bigger motor:
(Getting much better on the TIG with more practice!)
Then assembled it all back together after modifying the gearbox cover to clear:
Had to modify the storage crate for clearance though:
It runs really well now, better than it ever has. Can actually take decent cuts without stalling! The new motor is not reversible though, but I never used it in reverse anyway, that is more for cutting threads and the like, where as I am usually making shafts or modifying washers to make hubs.
Because the lathe had sat for so long the belts have seen better days though:
So I have some on order, hopefully they get here before May 1st, not sure how much longer they will last and I need to use the lathe for the first part I need to make...
Typically, they are not available in Australia, I had to order from the USA...
