zcar63 Posted December 23, 2013 Posted December 23, 2013 Hi I thought that i would post some photos of my rear control arms and the jig i made ,i couldn't afford to buy them.Using Chromoly tube and the best rose joints i could find.The jig was the most time consuming job.I have made custom spindle pins from 4140 hitensile steel as they have to be a bit shorter than the standard ones. I made a jig to fit in the lathe to notch the tube,the tube is held in a jig on the tool post, and i use a 1" holesaw on a mandrel in the chuck.Sorry i haven"t got any photos of the lathe jig. Quote
Riceburner Posted December 23, 2013 Posted December 23, 2013 Nice skills I take it they are for 240/260Z, are you going to produce anymore? Quote
KatoKid Posted December 23, 2013 Posted December 23, 2013 Nice skills I take it they are for 240/260Z, are you going to produce anymore? What he said ^^^^^ skills and production Quote
luvemfast Posted December 23, 2013 Posted December 23, 2013 Great work Now the question is.......... Now you have the jig and development work. How much are the sets going to cost us? Quote
Moderators PB260Z Posted December 23, 2013 Moderators Posted December 23, 2013 Great work Now the question is.......... Now you have the jig and development work. How much are the sets going to cost us? If you have to ask, you can't afford it Quote
luvemfast Posted December 23, 2013 Posted December 23, 2013 If you have to ask, you can't afford it Dude. I don't even have an S30 Z, but collecting parts...... Just in case Quote
dat2kman Posted December 23, 2013 Posted December 23, 2013 You could run a nice little hobby business knocking those out? Have you done the calcs on material costings, your labour, a bit extra per unit for IP/development? Based on, say 10 pairs ? The more youu make the less your costs! These look very good, well done!

pauly_adams Posted December 23, 2013 Posted December 23, 2013 im in for a pair at the right price they look mint and the craftsmanship looks really good Quote
zcar63 Posted December 24, 2013 Author Posted December 24, 2013 It was quite a bit of work to set up.Once the jigs were made the rest came together in between other jobs. I have made this style as i think it is the most effective design for strength and adjustability. i am trying to encourage someone i know to do some stress analysis for me but is could be a long process, If any one is interested in knowing the costs please send a Private message Quote
dazzed Posted December 24, 2013 Posted December 24, 2013 They are the best rear control arm sets ive seen so far, I did have plans to fabricate my own but ,for affordability of the tecno toy arms and the time it would take to make I just purched a set out right, well done tho very nice workmanship.

Scoota G Posted December 24, 2013 Posted December 24, 2013 Now look what you have gone and done. Looks like you will have to go into business now. Very Nice Work! Quote
d3c0y Posted December 24, 2013 Posted December 24, 2013 The design looks the same as these ones, but yours are missing the rear sway bar mount. If you run an LSD you really want to run a rear sway bar from what i have read. I have a friend that is an engineer and can do the analysis on them. I was actually considering making a batch myself of exactly the same design. Quote
44014 Posted December 24, 2013 Posted December 24, 2013 Yeah they look good. Sway bar mounting point and a price and I may be interested! Quote
zcar63 Posted December 26, 2013 Author Posted December 26, 2013 Hi All Jake they picture you posted of some control arms has a striking resemblance to the one's i have made ,nothing is sacred !!! (Ha Ha).I am waiting for prices to come back form O/S for the rod ends.If anyone can help procure chromoly tube i would love to hear from you ,i brought my last length from Sydney.The cost of tube and freight to Brisbane is a bit steep .I run an LSD and took the swaybar off a long time ago i prefer it that way when racing,so i haven't added the swaybar mount to the set you see.It can be added if required. Cheers David Quote

Cheers David Yes just let others add the sway bar mount and then they can plate them, paint them or whatever. Quote
44014 Posted December 26, 2013 Posted December 26, 2013 Any idea on time ? I'm about to order those ones that jake posted but if you can do them cheaper even better! Quote
zcar63 Posted December 28, 2013 Author Posted December 28, 2013 Hi All I made enquires about rod ends a few days before Christmas,but had no reply as yet.The rod ends are expensive,a bulk buy would make quite a difference to price.If i can order them in a week or so ,add another week for freight and then manufacture which will only take few days.this is the best estimate i can give at the moment. Cheers David Quote
Moderators Zedman240® Posted December 28, 2013 Moderators Posted December 28, 2013 Would they be able to be ordered without rod ends? As they can be sourced locally and be easier to send. Quote
luvemfast Posted December 28, 2013 Posted December 28, 2013 Contact Hypertrev on this forum for rod ends. He works at a bearing supplier here in Melbourne and is an ex NDSOC committee member. Quote
nat0_240_chevZ Posted December 28, 2013 Posted December 28, 2013 PM'd, would like to see these go large!! Quote
dat2kman Posted December 28, 2013 Posted December 28, 2013 I recently bought two sperical ball ends to go into front lower control arms, sheesh, yes, they are pricey, but they are very very good! No altering of geometry settings with these things! Quote
PeterAllen Posted December 28, 2013 Posted December 28, 2013 Do you have a weight, with or without rod-ends? Thanks Quote
zcar63 Posted January 27, 2014 Author Posted January 27, 2014 Hi Guys Sorry i haven't been very active on the forum .I am busy getting busy making control arms. I am adding gussets to the corners and a swaybar mounting point. The drawing for stress analysis is coming along.Communication will rod end suppliers is slow.As soon as i have completed the next pair i will get some mood lighting going and get some snaps of the sexy things Clarky93 1 Quote
