I've picked up quite old sport bench and weight stands from local recycling centre (two quid for whole lot!!)
After some time I discover that stands are completely useless for me, so I decided to keep the bench
and make bicycle repair stand from the stands.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: At First of All Project.
I made couple sketches/measurements some of them you can see. (sorry about quality I haven't got time to draw them in Autocad of so I scanned some)
The original weight stands are made from square steel pipes/profiles 40mm diameter.
What I used:
some old front hub with skewer (actually only axle with cones/nuts and skewer)
piece of 5mm thick plastic
Some 10/8/6mm screws, washers and nuts
10/8/6mm drill bits
Step 2: Stand
Basically I've took apart the stands completely, and made "fresh start".
I cut the main tube (vertical) so the bottom bracket will be on about 75cm just enough to work comfortably. I'm not a giant ;-)
Basically nothing to explain you can see on the picture how it's made.
The design of the feet might look strange but the point was to keep the stand folded and hang on the wall when is not used.
Step 3: Horizontal Tube (bicycle Rack)
Bike on stand is clamped by skewer to 100mm axle and also from the other side supported under bottom bracket.
I've measured all 4 bikes I have (frame sizes vary from small to medium: Mongoose M trekking, specialized S road, Giant M road, Giant S MTB ) and is more less similar distance ~60-65cm between bottom bracket and fork axle. Fortunately the weight stands had adjustable height so I've made the horizontal pipe adjustable for future flexibility.
details of the axle and skewer you can see on the picture and sketch.
Because the smaller pipe was slightly wobbly I attached pieces of plastic at the end.
On the other side I screwed two pieces of thick plastic to support under bottom bracket and make a gap to prevent cables touching the rack (see photo)
Step 4: Joining Two Pieces (stand and Rack)
The only part I've made (apart from cutting and drilling) was bolt for joining
bottom piece and horizontal tube. Sketch showing the idea and on the photo you can see how I've actually made it.
I've used piece of C shaped aluminium profile (see picture), but it can be made from strip of metal (alu/steel) bended around the screw head to prevent rotating during fastening nut.
The other thing is to figure out where approximately will be the centre of gravity.
Obviously that will be different for a different bike but you won't need that accuracy just roughly idea. Finally I've made a hanger for a front wheel (see pictures)
Step 5: Final Thoughts
It's quite handy to have all necessary tools on the stand, so you can attach small bucket/box/tin and also a piece of plastic gutter underneath chain will prevent grease, degreaser etc... dropping on the floor.
