Ognib Posted September 28, 2015 Author Posted September 28, 2015 Eyeball engineering in motion.While I'm hand shaping on the belt sander & getting it too hot to handle, I've got another one hanging on the fan cooling.It cools slower than it gets hot & the fan helps to accelerate the cycle.
Twokidsnosleep Posted September 28, 2015 Posted September 28, 2015 I just love this No digital this with computerized that on a multi axis cutting whatzit.....you just make a jig, set it up old school and mill away Very impressive
Ognib Posted September 28, 2015 Author Posted September 28, 2015 Thanks Scott, appreciate that. There is a certain "charm" in working by hand & I enjoy the challenges & the results when I get it right. But it's hard to match the absolute precision of the digital age with hand work as witnessed by the fact that I have had to do multiple takes on some parts in order to achieve my desired results. Getting there.They are in 50 grit from the big belt sander & only semi finished.Hard to do finish work on it as the area being cut is facing down & I can't see the contact area...but it's quick for rough in.True up the lines & eliminate the scratches by hand.Couldn't resist going a bit boutique ish on the design...a little out of character for me, but what the heck.
Ognib Posted September 28, 2015 Author Posted September 28, 2015 Still got to do an oil pan & at that point, engine will be pretty much all roughed in & I can start dressing it all down together...make it fit.Need a plug of epoxy under the corner of the rocker box for it to set on.
futurattraction Posted September 30, 2015 Posted September 30, 2015 I'm totally stoked about this build, Ray. Hand fabrication at its finest...
Ognib Posted October 1, 2015 Author Posted October 1, 2015 Thank you, Scott...always good to see you. Been watching your parts going on 10 thumbs project...very nice stuff, kudos!!!! I think these are Winters QC units.See what I can do about carving one of these with my current equipment.
Ognib Posted October 1, 2015 Author Posted October 1, 2015 We got chips. Roughed in the shape on the band saw & final shaping on the spindle sander.
Ognib Posted October 3, 2015 Author Posted October 3, 2015 Thanks for looking, guys. Building side covers for the rear end.Here's my procedure.Having neither mill or lathe, I'm forced to be innovative & think outside the box to achieve my desired results.Rough in on the band saw.Button head on bolt is the dia I want for the outside end.Big washer is correct for where it bolts to the center section.I'll work to these as my size templates.Jam nut keeps everything tight in the spinning drill press.Jigged a coarse rasp in the vice to hold it steady as the spinning aluminum plug is lowered on to it.Slow going.But I'm getting the result I want.On to the next step.
Ognib Posted October 3, 2015 Author Posted October 3, 2015 Beginning the layout for the stiffening vanes & bolt hole bosses.
Twokidsnosleep Posted October 4, 2015 Posted October 4, 2015 That's just super. You are incredibly resourcefulI bet you would be scary-good with a lathe and a mill
Ognib Posted October 4, 2015 Author Posted October 4, 2015 Thanks, Scott.Squared a line off of the degree line & set the square on it for doing layout up the side that's centered on the bore.
Ognib Posted October 6, 2015 Author Posted October 6, 2015 Draw a few lines to help me visualize how it all fits.
10thumbs Posted October 6, 2015 Posted October 6, 2015 Very impressive Ray! Looking good. Very skillful. Nothing looks more like metal than metal, and the stuff looks great on a model.
Ognib Posted October 7, 2015 Author Posted October 7, 2015 Thanks, Michael. Nothing looks more like metal than metal... Couldn't resist...love my mock ups.
Ognib Posted October 8, 2015 Author Posted October 8, 2015 More procedure.My solution to not having a rotary table.Washer keeps the aluminum work piece slightly off the vice.Nuts are in the vice.Everything is solid & plumb.Accounted for the thickness of the washer with a piece of .092...used a piece of .062 & set the depth stop loosely to it.This will give me a 1/16"...1/2" @ 1:1... base for this side of the side cover where it bolts to the center section.Centered the lay out mark in the vice opening & with the bit centered on that mark it will run with the axis up the ramp to the center of the piece.I'm employing trippple quadruple redundancy in this set up...I've got an entire sunday invested in the side covers at this point...got to get this right, the first time!!!
Ognib Posted October 9, 2015 Author Posted October 9, 2015 Since this is an independent rear suspension, I'm leaving plenty of material here so I can bolt up a bearing hub to support the inner u joint on the axle shaft.Start big & whittle it down to fit...eyeball engineering...
Ognib Posted October 9, 2015 Author Posted October 9, 2015 Waiting on a cutter bit so I can proceed on the side covers.In the interim start roughing these in.
Ognib Posted October 9, 2015 Author Posted October 9, 2015 Thanks for looking, Bo. Appreciate the comment!
Ognib Posted October 11, 2015 Author Posted October 11, 2015 Doing some studying this morning & found this.Some of you may find it helpful & informative. http://www.csgnetwork.com/screwinfo.html
jeff f Posted October 13, 2015 Posted October 13, 2015 Wow Ray , quite an undertaking . Impressive . You asked me about tooling and its not really an issue in my situation .But I would look at McMASTER-CARR for your machining needs .Jeff.
