  • Building Custom Mini Wheel Tubs for Pile House

    One thing a lot of longterm builds have in common is that the builder or owner tend to change their minds throughout the build. This has definitely been the case with Project Pile House. Over the past two years I've changed Pile House from being a "thrown-together" type build to something a bit more thought out and nicer. Even small items like wheel and tire combo have changed and caused me to go back and adjust things as needed.  Click Here To Read Full Post...
  • Building a Fuel Cell Cradle and Feeding Pile House with Fuel

    Lately I've changed gears on Pile House and I've decided to start working on getting Pile House moving under its own power. I decided to order up a plastic fuel cell from Jegs first. Once I began test fitting it at a few different spots on the chassis it was obvious that the only place I could fit it under the bed was behind the rear axle.  Click Here To Read Full Post...
  • How to Build Custom Cafe Racer Motorcycle Handlebars

    I've had my hands full with my four wheeled projects lately and I haven't been giving my little "cafe" motorcycle; a DKW RT125 much attention. I recently decided to build a set of clubman style drop bars for it. My problem with off the shelf parts are that I usually end up modifying them or they just aren't quite exactly what I want for my projects. I decided rather than wasting $100 or more on a set of bars I may not like the dimensions of, I'd build my own from scratch. Below is the cliff-notes version of the build. Hopefully this can give you some guidelines to follow on your own build.

    Above you can see the riding position on the bike with the original handlebars and the custom seat we made in the last tech series.

    I started by taking some 1/2" round steel bar and bending two identical halves into a rough shape that I liked and welding them together in the center. I took dimensions from some other bars that I liked and tweaked them to my liking. I decided that I wanted a pretty aggressive drop and a slight sweep forward to get into a sportier riding positon. This concept is the same basic way I'd be building the real bars.

    We started with 7/8" DOM tubing for the bars. DOM tubing is a seamless piece of tubing and is the strongest option for making something structural like a set of bars for your bike. DO NOT skimp and try to use thin conduit or anything like that, you're putting yourself and others at risk! We then took a piece of TIG filler wire and recreated the first bend in the tubing we needed from our round bar template. This allowed us to use the filler rod as a guide when we were making the first bend. We marked out the length of material the bend would take up and set the tubing with the starting line at the center point of the bottom roller in the Eastwood Pro Former Tubing Bender. We then pumped and bent the tubing until it was just a little further than the bend we needed on the TIG rod guide to combat the spring-back of the metal when the pressure was relieved.

    Once we had our first bend we slide the tubing into the stem and checked to make sure that it had the drop I wanted. Here you can put the tubing back in the bender to tweak it a little further if need be. We then marked out the length and center of the next bend to give us the first half of the bars. Depending how close your next bend is to the first you may need to spin the tubing around and come from the opposite direction as the first bend (just remember which way you want to bend!). At this point you also need to make sure that the tubing is set so that your next bend is parallel to the first bend. If you want some slight forward or backwards rake to the bars you could make this second bend just a little off from parallel, but it's tough to replicate multiple times. Again I bent the tubing to match our guide and we test fit it again to make sure that the we had the shape we were looking for. This is where you can stand back, squint your one eye shut and get an idea of what your bars will look like. Take a break, grab a snack, crack open a drink and get ready for the tricky part of this project next.

    This is where it gets tricky and I'll admit I ruined some material and had to start over a couple times. When you begin marking out your next bends they need to be perfect to allow for them to match AND you need to make sure all bends are parallel. With a good measurements, a helper to keep it all straight, and a little bit of luck, you could make a set of bars out of one piece of material. I decided after a couple attempts to make the bars out of 2 separate pieces and then sleeve, and weld them together. This also allowed me to keep my bends as close to the side of the forks as possible since I could trim them to size. I chose to shave down a piece of tubing that slipped inside the 2 pieces we bent and used the MIG 175 to join them with a plug welds, followed by butt welds with the TIG 200 DC . I left a gap so that I could get the TIG torch into the gap and melt the inner sleeve to the bars and also enough room to add filler to make it a seamless joint.

    After I had the pieces welded together I test fit them on the bike and marked out where the levers, throttle, and grips would sit. With everything marked out I could cut the extra length off of the bars. For most modern bikes the throttle is all one piece and you can just slip it over the bars and fix it in place. On my bike I needed to cut a seat for the throttle slide to sit in (the little aluminum parts seen in the pics above).

    With the bars welded and cut to length, I installed my throttle, grips and levers. The final look is exactly as I wanted and the riding position is how I wanted it. The bars still allow for full turning radius and fit me pretty well, so I'm pretty happy with them. Now that the bike is just about how I want it to look I can button up some mechanical repairs the bike needs and then make a small rear bobbed fender and the bike is ready for the road! Stay tuned, I'll show you how to build a simple rear fender for your bobber or cafe racer from scratch with Eastwood Tools next!

  • Building Door Frames to Match the Chop

    It's been a while since we talked about the roof chop on Pilehouse, but I've been doing a lot of boring work on the smashed up old roof getting it satisfactory. Since then I decided to finally finish building the doors to match the roof. I took some pictures as I did the drivers side to show one way to do it, and I did the passenger side an alternative way to show another way you can tackle this project. We shot the video on the passenger side, but in the photos here you can see the other way to go about it.

    Just like chopping the roof down, we needed to take out some height from the top of the door, split it in half, and add some width to it. That's why it's extremely handy to keep original metal that you cut off of the truck. I started by splitting the top of the door in half so we could mock up the two pieces so that they sat where we wanted them to in the door jamb.

    I started with the rear portion and held it in place in the door opening and closed the door until the post met the top of the door I was holding in place. From there I made a mark on the pillar where the 2 parts overlapped. From there I could cut the excess off of the door. In the front of the door I needed to take the extra material out of the top of the door since that was the straightest part of the upper front portion of the door. If at all possibly you always want to take material out of the pillars, doors, etc where the pieces are straight and the most uniform. Cutting them on a curve makes it VERY difficult to piece things back together smoothly and get your angles correct.

    Once the pieces were cut I temporarily tack welded them to the edge of the roof to get them sitting about where I wanted. With the tack welds I could still adjust the parts without them being permanently mounted. This way I could shut the door and line everything up how I wanted.

    Once the front and rear sections of the door were about where I wanted them I grabbed the piece of the door I cut out of the front. This portion of the door was very close in size to the center and only required minor tweaking to get the backside contours to match up.

    From there I was able to tack weld and adjust everything how I wanted and I could weld the seams all together. On the drivers side I hadn't fully cut and ground the drip rail off so I went about mocking up the door pieces. Either one will work, just be sure to use paint stir sticks or similar as spacers to leave room for seals in the door jam. With the doors welded back together the full effect of chopping the roof is visible. I think this mild chop really made Pilehouse look better. My next plans are to customize the hood and build a custom tailgate, so stay tuned for more updates.

  • How to build a Custom Motorcycle Seat

    The custom motorcycle hobby is HUGE, it isn't just Harley Davidsons that are being modified these days. Enthusiasts are building custom motorcycles out of anything they can get their hands on. One thing that everyone seems to have an opinion on is what their seat should look AND feel like. Some are ok with buying a seat out of a catalog, slapping it on and calling it a day, but if you're anything like me, the satisfaction comes from the process of building something custom myself.

    I recently shared the story about my adventure to get myself my first motorcycle project; a 1952 DKW RT125 and hinted at my plans for the bike. The other week I finally got some time between my other projects to do something about the "beach cruiser" seat on the DKW. After staring at the bike for a while, I decided that the seat that came on the bike was far too large for the bike and sat too high. I think the German designers may have had a rider in mind that had one-too-many servings of schnitzel and needed an extra large seat to hold them. Aesthetically speaking I think it really looked out of place. I plan to keep the majority of my modifications on the bike reversible, so I opted to remove the stock seat and make my own from scratch (using Eastwood Tools of course!). I liked the general shape of the stock seat, but not the size, so I decided to use the original seat as a pattern when making the seat frame up.

    I know some take a piece of sheet metal and bend it over their knee, drill some holes, attach some springs, and call it day when they make seat pans, but I wanted something a little more like the original. The old seat used round steel bar stock and some small diameter tubing to make up the frame. I started by stripping off the rubber seat cover and taking some measurements. I decided that the seat mainly needed some width taken out of the rear portion to make it the same width as the tank to look more proportional. I drew up a pattern for the seat pan and began the project.

    I used some 1/8" round bar to make the frame of the seat. I first tried to make the entire frame out of one piece, but it was extremely difficult to get the bends to all line up the same. So instead I opted to make each bend separate and TIG weld them all together to make the frame. I started by making the front "nose" of the seat first. I decided to use the bar grooves in the Eastwood Slip Roll to make the bends I needed for the seat frame.

    After a few passes through the slip roll I had my first piece matching the nose of the original seat. I repeated that process as I started working my way back on the seat. I like to bend with a piece of bar stock that's longer than what I need so I can cut the excess off to make the bends land in the same spot. As I made my pieces I laid them out on the pattern to make sure I was keeping the correct shape.

    Once I got all of the pieces made up to form the frame I taped them in place. I then worked around the frame and fusion welded each joint together with the Eastwood TIG 200. Once I had the frame welded into the shape I needed, I found I needed to put a slight curve into the center of the seat to get the overall curve shape I wanted. I ended up using a torch to heat the center and bend it a little to get the gentle curve needed.

    Next I cut out the pan for the seat using my manilla folder as a pattern. I purposely cut the 18 gauge metal a little larger than the pattern so I had some room for error. I then centered the pan over the frame and clamped it in place using a set of Eastwood Mini Weld Clamps. Once the pan was clamped I used the TIG 200 to lay a number of small welds to connect the frame and pan together.

    With the pan welded to the seat frame it finally started to look like what I had envisioned. I removed the excess metal off of the seat pan so that it was flush with the frame with a flap disc and an angle grinder. I then welded mounting tabs with studs on the bottom of the seat and attached the seat to the original seat bracket. With the seat mounted up, I decided to move the seat back. I used the front hole on the seat bracket and mated it to the rear hole in the frame. I then dropped the back of the seat bracket down to get the seat position a little lower. After mounting it all up I have made a custom seat that sits lower and looks more proportional without modifying the bike in a way that it would be difficult to return it back to stock.

    With the seat mounted up I checked my seating position and it feels a lot less like a bicycle and more like a motorcycle. I definitely will need to make a bobbed rear fender that will keep my rear end from getting caught in the tire, so that's one of the next projects. I plan to make a new set of bars with the help of the Eastwood Tubing Bender next. The new seat and the bars I plan to build should get the riding position more how I want. Slowly this old bike is taking shape. Watch this space for future updates.
