Eric MacNeil Version

  • 1/2"x12" pipe with welded flange

Base multimachine.jpg

Improvements:

  • Use square tube so it has a flat surface for mounting vertical slide

//Since solidworks is currently in a state of semi constant crashing I'm going to upload as much of the information that I have used in designing what I have designed bill of materials.


solidworks is working again I Will try to upload models of the spindle in the next couple days and designs for the slides as well. I have started making production drawings and writing steps for manufacturing each of the parts.


bearings for spindle

33012/Q 60mm by 95mm by 27mm tapered roller bearings 2X ~100$ each


spindle pipe

2 ½” XXHY pipe 18”? 2.375 nom O.D. ~30$

3 ½” sch 80 pipe 12”? ~30$

2 x 1 ½ x 12” steel flat bar ~20$


pipe XXHY for nut on end of spindle

v-belt pulley

spacer/seat for rear seal (could be v-belt pulley)

seals 70mm by 95mm by 12mm (seats on pulley or spacer)

seal seat for front of spindle



part sources

SKF for bearings and seals but equivalent avalible from most major bearing companies (price check through mcmaster.com or internet)

west marine for resin epoxy system (523.98 for 5.29 gallons, mixed with 85% aggregate yields 35.25 gallons of E/G concrete, 4.715 cubic feet

landscaping supply for aggregate (I bought river stone 3/8in size for $4 for a five gallon bucket or some such, $6-7 per cubic foot, and play sand can be bought for ~$6 per cubic foot)

steel prices based off of discount steel (http://discountsteel.com/)


books / resources

workshop practices book series

compilation of E/G thread from practical machinist (link Tips and Tricks for castig) (you may have to be logged in as a member of the group to look at the file, I'll ask if i can copy the file onto our wiki)
