The TLDR was A dont do it, B, buy a kit if you do.
1st - I'll probably do it despite the negative - its not for me, its for a friend.
2nd- I like to do everything the hard...
I'd like 400 rpm or so. Straight, reversable, and high torque. I'd like to be able to tap up to half inch. Was thinking of pulling whatever chuck off and replacing it with an ER collet system. Would grip the tap plenty tight, and I already have a set. Thank you for brand suggestions!
I agree. Breaking taps *****. They seem to become indestructible once broken in a hole. Most of the time I find they break because they did not go in straight to begin with.
The flex arm I am setting up should help with that.
Not sure what low rpm high toque tool would be appropriate, and not to heavy for the arm. Thought about adapting a 18v cordless tool... could use the clutch then..
Looking for a low rpm straight handle reversing drill. Anyone know of one other than the SIOUX that I've attached? Will be used for tapping with a flex arm
Were you happy with how it ran 1/4 inch alloy? Looking for a mig to weld up a 22 foot aluminum boat and this welder seems to be the best fit to do that. How was it with pulse on thinner aluminum.

Its bearings / not bushings ... still probably offshore. but one of the higher amp grinders for the price. I've got one and no complaints so far.. but if I did it again.. I'd likely step up to the 10...
JBWeld might be fine for Diesel.. Not sure....
Theres misleading information out there because you USED to be able to repair a gas tank with epoxy.. however most gas now CONTAINS ETHANOL. Ethanol eats most epoxy. So test the glue first with something small and submerg it in the fuel and see...
I would buy oversized diameter tube instead, and thread the inside of it. Get some rod ends threaded in and you are good to go! I find it easier to tap things than to run a die on them. You end up with a stiffer product that way too. Thats how I made strut bars for cars in the past...
I looked for a while before settling on a 8" king canada model.. Its 7 amps and ball bearings.. Seems decent enough for the price.. Only think I wish is that I payed a little more and went to the 10" model. Not sure of a better grinder for the price though.. For reference the dewalt model...
