Nik, do yourself a favor and fab a decent guard for that toolpost grinder, if not for the obvious safety while running then to protect the wheel when going to/from storage. A few careless bumps on that wheel and you’ve got a ticking bomb, unless you remove and ring test every wheel before every use. Take care. ☝️🤞🤙
G'day Mr Nik, A very interesting video. I'm looking forward to part 2. But hey I think its time for a new jacket. Looks like you've burnt that one. So thanks for sharing ✌️ Peace from Melbourne Australia.
Nik another great video. What surprised me is when you just touched the shaft with heat how much the shaft moved instantly about 30 thou. I never stop learning thanks
Curious to know what size motor you are using on your home brew tool post grinder, and, if you think it is adequate. I've got ideas on making one of my own, but I have no clue as to the HP rating of the motors used on the commercially made grinders. I've got a 1/3 horse and a 3/4 horse available to me at the moment. Next size up is 2 horse (absolute overkill in my opinion, and too heavy for this old f@&t).
TPGs aren’t typically used for roughing, just finish work. The determining factors then are diameter and effective width of wheels used. If you stick to wheels 3” - 4” and do a good dress the smallest motor will likely suffice. But you may want to use the 3/4 in order to run appropriate pulleys to get a high enough cutting speed (sfm). I’ve never found myself wishing I had less power.
Nik, I have a dumb question, how did you convert the measurement (X) you took over the original taper distance (Y) and come up with the angle in degrees (Z) to set the compound at? Thanks, also a very interesting video, I was also amazed at how much you could move the shaft with very little heat, I've never seen that before. The heat gives you much better control than smacking it with a hammer.
@@Neilukuk Sorry, I jumped the gun., #2 will be posted tuesday. I found the angle by running an indicator across the existing taper then adjusting my compound until the indicator read zero from one end the the other. I'm sure there is a calculation, unfortunately I was never good at math so I always answer these kind of problems mechanically.
@@NikColyerMachineWorks I found him, and watched some of his stuff. I find it hard to believe the machinist community would let him get away with such a claim. Straightening shafts with heat predates him by decades. What's with his creepy intro? Something off about that guy.
@@ShainAndrews I agree. I think he joined the MAGA crowd lately. You might find some of his older youtubes like 5 years ago or so. He really knows his stuff and has filmed some interesting projects. Try "American Crane"

NICE WORK NIK
Looks good so far Nik.
G'day Mr Nik,
A very interesting video.

Plus One for the jacket 🙂
Great video nik, keep'um coming.
Keith Fenner work here. 2:30 looks like it was spinning when that happened
Yes, you may be right.
Nik another great video. What surprised me is when you just touched the shaft with heat how much the shaft moved instantly about 30 thou. I never stop learning thanks
It always amazes me too.
Nik, if it's not a daft question, why did you not cut 1 inch off the other end. No taper machining needed. Regards from Australia.
Yes, but it would not have been as interesting to make a video about?
@@davidschwartz5127 It's also teaching people the wrong way.
Hope you have a spider to support the other end of the shaft.
good job on the taper

Watch #2 video. and it gets explained. I just posted #2 this morning.
@@NikColyerMachineWorks I don't see #2?

6:25 Who? Somebody find the source of shaft straightening?
Keith Fenner on youtube. Look him up.
