Another modified Joe's 2006 CNC
Reply with QuoteThis is how I made my own Bearing retainer nuts. Got the 1/2" x 10" Acme tapered tap at Enco, drilled my tap handle to take a 1/2" dia. solid shaft of brass. Then made shaft holders and bearing holder on my old CNC mill out of PVC scraps that I have. Attached the whole mess to a junk counter top I had, clamped it in a wood vice and started tapping!!The PVC plugs were cut from a junk chunk of 1-1/4" dia. PVC rod with a hacksaw, turned and drilled on my HF lathe to size then counter sunk, drilled and milled on my HF mini mill. I think they will work just fine and the price of em was free, even tho the tap cost around 65 dollars. I plan to tap my own floating nuts for acme rod so tap will get used again!! You MUST use a tap fixture to tap these things, I tried it without and it wobbles on acme rod, just hard to get a straight tap by hand. And be sure to run tap all the way thru and out the bottom, DO NOT reverse tap to remove.

Y-Axis pipes
and now that I'm ready for Y-axis building phase, wouldn't you know it, no nice stuff around like I found before 
, so bought the normal badly painted 36"x3/4 gas pipe, with plans of smoothing it up some. The plan is to use end caps with a 5/16" hole drilled in the center and skate bearings mounted on em and rotated with a sewing machine motor I have. So far have got one gas pipe end cap done, plan looks good!! Had to turn a flat spot on end cap in my small 9x10 HF lathe, chuck was bearly large enough to hold it using outside jaws, and drill a 5/16" hole dead center. This weekend will do the other one, make the skate bearing holders and alum pully for motor belt, time permitting.
I tighten it up the last time but this time is a lost cause, my bad design on the Y-axis
. The bolts that hold the bearings are too long and keep bending, even at 5/16" bolts, and it won't handle the power, weight of the router. Just way too much vibration going on with it. So will go manual on cutting out parts for Joes 2005. The PipeDream crashed while I was making the PVC bearing holders for the pipe rotator, so had to come up with another idea. Will use the bearings I bought for Joes 2005 which have a 1/2" ID, because I made extra PVC bearing holders that where too big, all I have to do is make sleeves for the 5/16" threaded rod to fit inside the bearings. That way I don't have to redrill everything to 1/2" and buy 1/2" threaded rod. Have some 5/16" threaded rod already on hand. So found some 1/2" rod and did some lathe work on it...presto!! 2 each sleeves complete. All this, just to clean up two 36"-3/4" gas pipes...what a pain!! Just need to drill bearing holder blocks, cut some rod and mount all the parts on a board unless something else goes wrong.
