We are starting a new build diary here. Its going to be a very simple drag bike style frame. But its going to be tough enough for dry lakes or salt racing. The tubing is going to be a little thicker than drag racing. Nothing exotic. Its 1 1/8 inch .125 wall d.o.m. Its a double down tube single tube backbone. Your typical harley frame. Although any motor and transmission could fit into it. Its simple. Its inexpensive. And its something that probably half the people here could build.
The first step is making some type of fixture to hold your parts in place. It could be done with angle iron and some threaded rod. Some scrap tubing.
The first thing to do is build the neck. This particular bike I made my own neck on the lathe. It takes a bearing race and a timken bearing, one on the top and one on the bottom. If you can't make the neck a local machine shop would be happy to do it. Or I will do it for a small fee. The rear axle castings are off a harley davidson softail swing arm I like to use them because they have that 50's look. You can actually make them out of 1/4 inch cold roll plate, but on this bike I'm going to use these. The backbone and the seat post will be 1 1/2 in .125 wall d.o.m. Its going to have a 75 inch wheelbase with a 30 in long frontend and 45 degrees of neck angle(rake).
Enjoy the pics.

The first four pics were pretty much of the frame jig setup and the neck in place on the jig.
The next four pics will be the frame jig with the neck the axle castings and the front frame tubes bent but not fit.

its been cold this winter so im a little slow when the weather warms up i will be able to work longer days the bike in this build will just be a frame for a customer --it a very simple frame styled after the 57 harley frame --ive seen a lot of junk aftermarket frames and thought if someone watching wanted to build one they could just follow along --it doesnt take a lot a frame jig that can be made from just about anything --a bender although tubing can be bent around just about anything --and a good welder either a tig or a wire feed and some one that knows how to run it --the bender i use is a jd squared it works really will the bender is about 250 dollars then the dyes are a couple hundred each depending on size it will bend 1 in to 2 in round they also make dyes for square tube im not sure of the sizes i think they have a web site iv had the bender for about 14 years and would reccomend it highly thanks willie buchta

Well it is the first time in years that we have had a winter like this. Last couple years it was rain when it should have been snow. Besides you wouldn't have to live here all of the year. Go to AZ in the winter 8-).

.....................and this picture wasn't taken in Utah, but at my Mom's house 35 miles south of your place in the banana belt :evil:, and how many days were you without elect. last year in that ice storm. Maybe Blanding doesn't look that bad :lol:.
Willie sorry to mess up your new build. You are doing some really nice work and I'm watching and learning. Thanks.

Wille it appears you are going to run a belt for the final drive. Did you offset the motor to accomadate the width of the belt, if so how much?
Frame looks great!
Scott
-
i had to go back and look at the pics --the owner will run a chain the trans i used for setup just had the belt sprocket on it but i think the frame could run a belt --if someone wants to run a belt i would make the back of the frame wide enough for the belt --i would never offset the motor and trans ---maybe if it was a sidecar bike--funny that you mention it but i dont think a belt would last land speed racing and its way to hard to change gear ratios how is the frame coming on your bike how much rake did you decide on willie buchta
-
I am going to figure everything out tomorrow.
Looking forward to seeing your bike finished.

Never worry about putting in too many pictures Willie. Those of us who are builders can never have too many details shown. It expands our idea bank as we go through them.
You do nice work, generally in a very simple and straight forward manner.
