    Default Another ACME Triumph build.

    We recently started a Triumph build for a customer, So we decided to post some in progress pics.
    We're going to try to keep updating these as we go, until the bike is done.

    The bike started as a '68 T120R. The motor was pulled and completely pulled apart, and blasted to start fresh. The frame was also stripped and everything we didn't want or need was cut off. We also got started on our loop tail hardtail.

    We added a Timken bearing conversion kit with our own internal forkstop.

    The idea was to run a Sporty front end on the bike and Jay also wanted to run a Triumph front drum, which he felt was a much better looking wheel. That way you can run the drum brake and still have the newer suspension.

    If you are interested in running the Triumph wheel on your Sportster front end, give the shop a call or email us.

    The Sportster Trees had to be modified to use the internal stop, as well as fit right on the Triumph frame.
    The old fork stops had to come off and the suface smoothed, drilled and tapped to fit the rest of the stop.

    The top tree gets cleaned up by removing all the unnecessary stuff.

    Trees are looking real nice and clean. Love your guys work. Can't wait to see this project step by step. Do you sell the internal fork stop as a kit?

    Pete, We do sell them. They're not currently on our website because it's being updated, but you can contact us either by phone (603) 524 2263 or email Orders@acmechoppers.net.

    DeadMansluck, We do the blasting in house as well as any polishing, we send out any chroming, painting or powdercoating.

    The donor bike for this project came from a lot we purchased from a guy in Louisiana, casualties of hurricane Katrina, So you can bet things started off with no where to go but up.

    But these proved to be a minor inconvenience in Robert's capable hands.

    In reality, He wanted me to point out that the cylinder was unusable, hopelessly seized. The cylinder had to be unbolted and separated from the cases as far as the rods would allow. The cases were then split and the cylinder, rods and crank assembly removed altogether.
    He was able to get everything apart to salvage the crank and rods, but the water damage to the rods may be too severe for them to be usable.
    Everything was cleaned and blasted and the reassembly is underway.

    Default Looks Great!

    Those cases look great, what are you using to blast them with? Did you mask off the cam bushings or press those in after?

    We use plugs to protect the bearings when media blasting, and after that they get cleaned over and over again with super hot water .Sometimes they get a few tripes through the dishwasher too !

    Those internal fork stops are sweet.

    Wish my old lady would let me use the dishwasher to clean cases.

    Thank you for documenting this build.
    I love the look of the Loop Tail/Axle Plate.

    I'm curious about the internal fork stop, my apologies in advance if I sound completely dumb, but I have two questions about their installation:

    How do you manage to have the bearing cup perfectly in line?
    Photobucket

    How do you drill the holes to hold the other part?
    Photobucket

    Do you have pictures of these processes? (sometimes due to my english level, I miss some part of explanations, when too many technical words are used)

    On a stock configuration, does it give you lenght/hight problem due to the new material being added?

    Here are some updated pics from our Triumph build. In this update you'll see us get our rear wheel centered in our frame and get our fender mounted.











    Taking measurements for the rear wheel alignment.







    Laying out the chain for proper spacing of the fender





    Fender in sitting on the tire,the side skirt is way too long so we marked it and took about 1.250" off the skirt on both sides.



    Here's our fender clamped to the table so we can trim the skirt with a cut-off wheel .





    We clamp spacer with the radius we want on the corners of the fender blank, then sand up to the spacer to get a nice clean edge treatment. Simple and very effective.











    Here are the mounting bungs being turned down in our lathe.





    The mount lugs are .750" diameter ,and .250" thick with a turned section .500" in diameter and .125" long. This will pass through the fender and make the mount look like it's only .125" thick on the outside. The mount and threads are actually .250" with 5/16 - 18 threads.



    We are getting ready to mark out and drill the fender for the fender strut mounts we just made .We use the mounts and transfer punch that fits the I.D. snug .









    Then position the mounts and punch .250" form the edge of the fender









    Fender mounts finish welded in our fender.



    Here are the mounts we fab'd up for where our fender mounts directly to our frame.











    We waited till this step to install the top wishbone cross bar, it's easier to let the cross bar "float" and weld it in a position the works best for the fender mount .



    Here's our front fender mount again.











    Fender trimmed for proper chain clearance.

    Here is Wayne bending up a pair of fender struts for our Triumph build. He does them together in the vice and levels them for a perfect bend.















    Wayne uses this block to assure our struts are perfectly level.







    Wayne uses the digital level to assure they're perfect!





    DONE
