A little update.
Been busy with a lot of things, so progress has been slow, but I have slowly been upgrading my little mill to make the aluminum parts easier, faster, and have a better finish. The brackets were too big to do in one step with my original set up, I would have to cut one half and them re position the bracket to cut the other side. For the fronts, since its a angled bracket, instead of cutting a block of aluminum until I had the angled bracket left, I bought an angled piece of aluminum that had to be 6''x6" to get the need thickness of 3/4". This was so less material was wasted, but it was mainly that it would take too much time to take off all that material with my old set up. It also made a mess when I was done with my first aluminum front bracket, the chips would fly all over the room.
There were some errors made in first front bracket made out of aluminum, having to re-position the front bracket while cutting made it a challenge, so I decided to upgrade the mill before cutting the final pieces, this was a few months ago. I upgrade the y travel from 3.5 inches to 5 inches of travel by getting a longer base that allowed for more travel, then modified it more to get up to 7 inches. I also bought a longer x table that allowed for more travel, went from 8 inches to 11.8, and again modified the table even more to get 17 inches of travel out of it. I pushed the z column back 2 inches , hence getting the extra 2 inches of y travel previously mentioned, and also raise the z column up 3 inches. I built a flood enclosure, got a big pump and was ready for heavy cuts with flood coolant.
Well my home made power draw bar didn't have enough tension to hold the tools under heavy cuts so my tools were slipping. Also my belt would slip trying to take deeper cuts, it was a pulley that used a v-belt. I had had enough with not having reliable cuts so I upgraded the little 1/2 motor to a 1 hp treadmill motor with an upgraded power supply board as well, I also added a timing pulley to drive the spindle instead of the v pulley set up I previously had that would slip. Next was upgrading the power draw bar, I made taller plates to add more bellevile spring washers and added a larger piston to actuate the lever. This gave me more tension on the tool holders so they would not slip out anymore. Last was tramming everything back which took a little while, the z modification left it out of tram and it took me some work to get everything align when tightening the modifications down.
So basically I cut the aluminum brackets a while back, but it took to long and to make everything easier, I spent a few months upgrading the previously upgraded parts even more to get this little monster that I am pretty happy with now.
Now for the brakes......
I ordered a different hat for the rotor last week with different offset. The first one I bought last year was too shallow and cause the caliper to hit the rim so I had to use a 3.30 mm wheel spacer to clear. I decided I didn't want to use extra hardware, why not make a set up that fits correctly, so this time I measured everything up and I bought a hat with higher offset. Great news, the higher offset allowed for the caliper to clear the wheel and not hit, but the offset turned out to be 3.30 mm to high and it hit on a part of the suspension now. So having barely finished up all the upgrades to the mill last week, I decided to cut the rear of the hat down by 3.30 mm so I could clear the suspension instead of buying another hat, either way they don't make a hat with the proper offset. i cut down the hat and little mill did not disappoint, I was very happy with the results. Flood enclosure, flood coolant and a bigger motor, this thing was cutting deeper than my old set up would which was great to see. I cut the hat, mounted it to the ls, it cleared the suspension on the back side, and the caliper cleared the wheel, great results! So this will be my rear set up now: brembo caliper, wilwood 14" rotor 1.1" thick, no spacers need, perfect fit! My previous rear hat will now be used as my front hat to not let that hat go to waste.
Enough with all the yapping, now for some pics.
The huge piece of aluminum I needed to cut to get the angled front bracket. No enclosure,no flood, just a mist set up which made a mess and took forever to just cut it to size to be able to cut the actual bracket.
The upgrade went from this little gal
To this.... Made a flood enclosure and added the longer y travel base, but I still had the stock motor, weak power draw bar, v-pulley that slipped, stock x table with 8" of travel, stock z travel too.
Finally to big bertha! Its not a big mill but it has come a long way and is more than capable for my projects. This was right before finishing the new flood coolant set up so its a little messy but you get the idea. I also have my own 2 cars garage all to myself which great and I can actually work on my projects with room to spare.
Big bertha churning away, cutting like butter with the flood coolant.
Rear and front set up. The black is just an electro coating they put on for protection. The parts where the pads touch will get grinded down to the metal but the parts that don't will stay black and protected.
Rear set up installed, perfect fit and it fills in the wheels so much better than my dinky stock calipers and rotors. I also order a custom parking brake calipers made for vipers, yes vipers, they will be on the opposite side of the brembo, its just for the parking function, not for braking. These were the only calipers that would open enough to fit my 1.1" rotors, besides maybe brembos calipers but those are like 1100 bucks a pair, no thank you. I guy makes these and a few other custom parts for vipers and some other car that is no longer in production, always glad to help small businesses especially those in the custom parts field.
If you price this whole set up vs other BBK, I estimate about 4k for everything, 2k for fronts and 2k for the rears, which isn't too bad considering stop tech's runs like 2900 for the fronts and 2900 for the rears, that 5800. Its still a lot of money,too much money for most to consider dropping on their ls, but I'm already deep in the hole, whats a little more going to hurt. I know no one will follow with this , but its one more step for my ls to be unique
More progress to come on the fronts. I also need to design the parking caliper brackets which will use the dust shield mounting location to bolt on. I will post pictures when those arrive next week, I'm very excited to see them.
