Pete J. Posted October 21, 2016 Posted October 21, 2016 (edited) Ok, this is a follow up for Chris and Tim. I got the rotary table back from Sherline a couple of days ago and I am very pleased with there modifications. I can now get a bit within .5" of the top of a piece and almost flush with the end of the jaw with a collet used to hold the bit. The head contactling the Rotary table is still the limiting factor but it is much less of an issue. The first picture is the after and the second is before. You can clearly see the clearance difference. Edited October 21, 2016 by Pete J.
iBorg Posted October 22, 2016 Posted October 22, 2016 I've built a few brass chassis and have to say the challenge of getting the two sides congruent has defeated me more than once. What an idea with fantastic results to prove the quality of the concept. I will save this idea as one of must tries. Curious question concerning the rotary table.....did Sherline do that to a table you already owned or modify their typical production? It seems so obvious, you have to question why they're doing it the way they're currently doing it.

You have to call and order it. They haven't had much call for them, but then, if no one knows you have it, then I wouldn't expect much in the way of sales. I strongly urged them to put it on the web site.
comp1839 Posted October 22, 2016 Posted October 22, 2016 (edited) pete, feel free to bore me with the details. how did rotating the handle in any way fix the relationship between the rotary table face / chuck and the edge of the head to the spindle centerline? edit: forgot to mention, it would be best if when you show something like this you put the same mini carbide drill in the collet at the exact same depth and not change to a longer shank and larger diameter end mill to show your relationship change. the tooling change makes it look like extremely different.

Codi Posted October 22, 2016 Author Posted October 22, 2016 Thanks for the comments guys regarding the mock-up and where the chassis sits at this point. cheers, Tim
futurattraction Posted October 23, 2016 Posted October 23, 2016 Haven't been on the forum much recently, so am catching up. Tim, your chassis assemblies are out of this world - and such a simple, but effective way to align and hold them. Your front wheels came out super, too...!

Dave, I really don't want to hijack Tim's thread with this subject. I will send you a private message with photos that explain it better. Anyone else who wants information can pm me and I will answer questions.
Art Laski Posted October 25, 2016 Posted October 25, 2016 You're continuing to amaze me, Tim! The brass work is bringing back memories, and reminding me I have some unfinished business somewhere...
Codi Posted October 29, 2016 Author Posted October 29, 2016 Hey Art, would love to see you back at that one. Got the 2 halves of the chassis combined. In the 1st pic you can see 3 brackets I made to support the chassis for the remainder of the project. 2 machined, 1 made of brass to support the rear when lining it up to the engine. The aluminum one will be the primary and used to do the brakes / hubs etc. The front bracket I machined so it would line up the frame rails and a connecting rail that will limit back and forth on the chassis during fabrication. cheers
cobraman Posted October 29, 2016 Posted October 29, 2016 Beautiful work ! Very impressive ! You da man !
iBorg Posted October 29, 2016 Posted October 29, 2016 There's more craftsmanship in your jig than most finished models. I can learn a lot looking at your in progress shots.
Mooneyzs Posted October 29, 2016 Posted October 29, 2016 Tim.... That chassis is one fine piece of Work. Top Notch stuff right there. Love that you have gotten the half's together. I also love the Jig you fabricated up to hold the chassis. NO better way than having a Jig to keep things all lined up a square. You are making me want to build a brass chassis really bad....lol. I can't wait until your next update. Nice Job Tim. keep up with the great work.
John Teresi Posted October 30, 2016 Posted October 30, 2016 Tim......OUSTANDING!!!!!......you are just to good man.......love your work Tim
Nytrozilla Posted October 30, 2016 Posted October 30, 2016 Good Grief !!Even the jig is a work of art.
DrKerry Posted October 31, 2016 Posted October 31, 2016 Hey Tim, do you build real cars as well??? I only ask for the reason of how well you detail the smaller scale stuff. It looks just like the real deal!!!!!!!! Keep up the great work!!!!!!!
Codi Posted November 2, 2016 Author Posted November 2, 2016 Many thanks everyone. Started the headers on Monday and wrapped them up this morning. 40 degree swept back shorties. Scale about 16" in length. They aren't attached to the heads permanently yet as I have to add the bolts and will probably paint them flat black or white. cheers, tim I wanted them up and away so that the bottom end of the block & girdle would be more visible.
Nytrozilla Posted November 2, 2016 Posted November 2, 2016 This, to me Tim, is amazing. I knew we had "something" in common that linked us together in the Greater Design of the Cosmos and Humanity in general. We have the same exact ruler !!!!!!! I'm serious Dude. Mine is Exactly like yours. That's a total mind blower. Nice start on the headers. That's all the progress so far, huh? 8 pieces of bent tubing. WW !!!!!! Sorry, I'm medicated.
Codi Posted November 3, 2016 Author Posted November 3, 2016 Thank you Dave! Joe, oh Joe. Yes, we have the same ruler, but I'm still trying to figure out how to use it. There was a lot of brass tubing that "died" to make those buggers. Each one was annealed about 10 times to get the bends without crimping and I found a quick method to fix those that did a. You should see the burn on my stomach where I dropped the pliers during one torch session and it melted the top, and my skin, almost instantaneously. Learned a quick lesson there my friend. ALWAYS wear my smock, somehow I forgot to put it on that time. So, yeah, 8 little pieces of bent tubing is all I got to show for it. Cheers, Tim
John Teresi Posted November 3, 2016 Posted November 3, 2016 Tim......amazing headers.......you make everything so perfect and correct.......looking goooooooood!!!!!!!!
